9d24e906a8 text_area: fix interplay of shift with selection
Without this patch, the text area would mistakenly delete the characters
types after placing the cursor with the mouse as soon as shift is used
as modifier.

ab5770c492 sculpt: improve USB hotplug handling
- Don't reset sculpt partition on USB changes whenever ram fs is
  selected for use.

- Reconfigure runtime immediately when plugging USB devices.
  This prevents the usb-block driver and part_block from
  dangling in the graph. They disappear immediately now.

e54e4dd532 sculpt: anchor popup position at '+' button
This patch restores the anchoring of the popup menu to the original
behavior, placing the popup to the right of the '+' button. The
anchoring got lost due to the recent structural changes of the GUI,
which affect the hover XML structure.

net:
* increase queue size to 1024 (more stable on Linux)
* use mac address from Nic session instead of random one
* handle data that is larger than rx descriptor correctly (copy less)
* clear descriptor header (12 bytes) on rx

generic:
* always use 'avail_idx' (tx and rx)

60f5d0e34a gems/animated_geometry.h: increase value range
The value range supported by the 'Animated_rect' utility is constrained
to 2^11 by the used 32-bit integer type. The interpolation is performed
on fixpoint numbers with a fractional precision of 10 bits. The
non-linear interpolation as performed by the 'Lazy_value' utility
involves squaring the values. Hence, the interpolated integral values
must not exceed 2^11 (2*11 bits for the square plus 10 bit for the
fractional part require 32 bits). This range is too small for
high-resolution displays. Hence this patch replaces the 32-bit integer
type by a 64-bit integer type.

3a2895af19 wm: reset pointer position on leave event
The wm used to remember the last pointer position when observing a leave
event. With such a stale pointer position, the wm would eventually
wrongly create an artifical motion event when a supposedly hovered
window changes its position (during an animated move). This can lead to
the propagation of the stale pointer position to the wm client, which,
in turn, may interpret the outdated position (e.g., the menu view would
report a wrong hover state).

This patch removes the stale state by resetting the '_pointer_pos' when
observing a leave event.

52e582132f os/vfs.h: handle corner case in join function
When specifying "/" or "" as rel_path to the 'Directory' constructor,
the constructed directory should refer to the same directory. The
implementation of the join utility did not consider this corner case. It
occurred during the attempt to use fs_query with "/" given as path.

This patch also adds a Directory::Entry::dir accessor that returns true
if the entry is a directory.

9d7a58f6a7 dde_bsd: update audio driver to OpenBSD 6.6
Besides updating to a newer version the update adds the AC97 ICH driver
and addresses shortcomings with the OpenBSD emulation environment:

* Fix 'delay(9)' implementation - it now properly uses 'us' as unit,
  which results on faster initialization of the drivers.

* Fix LOG output that got lost during commit f23579532 and bring over
  the printf implementation from dde_linux for more structured
  printing.

* As said the driver now recognizes the AUICH devices. So far it was
  only tested with the device model in VirtualBox where it produces
  stuttering audio, investigating the cause is still ongoing.

8a7deae238 ahci: switch to request stream API + structural changes
- Remove dated 'Block::Driver' front end and implement
  'Block::Request_stream' front end
- Remove all dynamic memory allocations but DMA memory allocations
- Remove 'Platform_hba' and implement platform specific functions in
  'spec/<platform>/*'
- Ata and Atapi don't inherit from 'Port' any more, but are a member of
  'Port' as a protocol implementation
- Use platform driver for MMIO mappings (x86)
- Exchange stateful initialization of Ata/Atapi with a sequential
  initialization using 'wait_for_any' and 'retry' patterns
- Fix Atapi initialization by setting the byte count limit
- Set FIS receive base only when Cmd::FRE is disabled and Cmd::FR is 0
- Put everything in namespaces ('Ahci', 'Ata', or 'Atapi')
- Ata decides during read/write operations to use native-command queuing
  or normal DMA requests
- Remove port claiming logic (is now done via 'Constructibles')

ff5175ec76 libc: synchronization primitives based on monitor
The libc monitor facility enables the execution of monitor jobs by the
main thread when the monitor pool was charged. In comparison to the
current suspend/resume_all mechanism the main thread iterates over all
job functions in contrast to waking up all threads to check their
conditions by themselves. Threads are only woken up if the completion
condition was met.

This commit is the result of a collaboration with Christian Prochaska.

96cde52838 vfs: make <rom> fs robust against invalid ROMs
An invalid ROM dataspace can occur, for example, when requesting a ROM
from the report_rom service before the first report was posted. Such a

Hence, the corner case of an invalid ROM dataspace should be gracefully
handled instead of causing an abort.

f82e7df0ba os/buffered_xml.h: support for generating XML

The patch also add a deprecation mark to the original 'xml' accessor
because copying 'Xml_node' objects (here as return value) is dangerous.
The new 'with_xml_node' method should instead be used to access the XML
content stored in the buffer.

cd92b32622 libc: close all open FDs on exit
This is important to issue sync requests for written-to files.

As the closing must be performed by an atexit handler, it happens at a
time _after_ libc plugins are destructed. Consequently an FD allocated
by such a plugin results in a close error, which in turn, does not
destruct the FD. We ultimatedly end up in an infinte loop of
re-attempting the close. For this reason, the patch changes 'close' to
be robust against this special case.

This is generally not a problem because libc plugins are phased out.
However, at present, the libc_noux plugin is still important. With the
changed 'close' in place, there occurred an error message "Error: close:
close not implemented" at the exit of each noux program. This patch
removes the error printing from the libc plugin mechansim to avoid this
noise. The error messages are not important anyway because the
deprecation of the libc plugin interface.

3897ddea03 cxx: don't rely on global ctors
This patch removes the global variable 'blocker', which was expected to
be constructed via the global ctors. This mechanism, however, is not
used for the base library, which resulted in the use of an unconstructed
object. Specifically, the spinlock of the 'Lock' of the 'Registry'
defaulted to the LOCKED state (value 0), which eventually would lead to
a deadlock in the contention case of the cxa guard.

I could observe this deadlock once on during the component startup on
base-linux during the construction of the 'startup_lock'.

This patch fixes the problem by explicitly initializing the registry
of blockers via an init function.

b7fbe65ff2 libc: fork/execve improvements
- Close FDs marked with the close-on-execve flag
  (needed for 'make', which sets the flag for the pipe-in
  FD of forked children)
- Update binary name on execve to use as ROM for subsequent fork
- Enable vfork as an alias for fork (needed by make)
- Purge line buffers for output streams during execve because they
  may be allocated at the allocation heap, which does not survive
  the execve call.
- Consider short-lived processes that may exit while the parent still
  blocks in the fork call.

With these changes, the website generator of genodians.org works without
the need for the Noux runtime.

6b6915e304 ttf_font: fix artifacts with large font sizes
This patch is a follow-up fix for "ttf_font: prevent out-of-bounds
access", which produced sporadic single-pixel artifacts with large font
sizes, e.g., with the monospaced font set to 24px in Sculpt.

The artifacts occurred only for some horizontal sub-pixel positions, in
combination with the font cache, and after the rendering of '>'
characters. They were ultimately caused by the missed clearning of the
first pixel of a glyph where x0 is 1 (e.g., the character 'd'). In this
case, a pixel from the previously evicted cache entry (the '>') shined
through. The patch fixes the problem by clearing the glyph starting from
the first, not the x0's, pixel.

* Use memcmp, memcpy, memmove instead of the former character-wise operations.
* Sanitizing of log input and log patterns now works more generic through the
  new Filter class for all replacements/removals.
* Sanitizing is done as soon as a string is available and remains for the
  lifetime of the test.
* Sanitizing doesn't interfer with the matching algorithm.
* Decomposing into small clearly named functions.

4622ddb46f nitpicker: add version attribute in clicked report
This patch addresses a corner case where the nitpicker focus is not
solely defined by mouse clicks or (exclusively) by a window manager, but
by a policy component that takes mouse clicks and other policy (e.g.,
a lock screen) into account. It ensures that each click that follows a
focus change (however initiated) results in a new "clicked" report even
when the report looks the same. To allow the policy component to
uniquely distiguish subsequent reports, the report features a new
'version' attribute.

c51b4b5742 New VFS plugin for emulating POSIX pipes
Add a new plugin for creating pipes between pairs of VFS handles. It is
intended to replace the libc_pipe plugin, one of the last remaining libc
plugins.

In contrast to the libc_pipe plugin, this plugin defers cross-handle
notification until I/O signal handling rather than block and unblock
readers using a semaphore. This is a performance regression in the case
of multiple threads blocking on a pipe, but shall be an intermediate
mechanism pending renovations within the libc VFS and threading layers.
As a side effect, threads blocked on a pipe might not be resumed until
the main thread suspends and dispatches I/O signals.

The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin
and tests both local pipes and pipes hosted remotely in the VFS server.

Merge adaptations (such as EOF handling, adjustment to VFS/libc
interface changes) by Norman Feske.

9b7915facb vfs server: redesigned internal control flow
This patch reworks the VFS server to become easier to understand.

- The packet-stream handling is hidden from the node types.

- Introduced the notion of a "job" as an abstraction from the raw packet
  stream.

- The processing of requests is split into three phases:
  (1) accepting new jobs,
  (2) the execution of jobs, and
  (3) the delivery of acknowledgements.

- There is no longer a global fifo of pending nodes. Instead, each
  session has a fifo of "active" nodes, which are nodes that wait
  for the completion of jobs.

- The Io_node type no longer uses virtual functions as hooks for
  the derrived classes. Instead, it provides a number of utility
  functions.

- The control flow of the 'Io_progress_handler' is now the same as
  for the session-local packet-stream handler.

- Removed dependency from 'file_system/node.h', which is a relic
  from the ram_fs.

While reworking the code, the following semantic changes were made
additionally.

- The handling of SEEK_TAIL no longer overwrites the file content at the
  end of the file.

- Removed diagnostic message at session-creation time.

- Write loop for continuous files

60d37f690c packet_stream_*: fix missing dissolve on exception
When the construction of a member of Packet_stream_*::Rpc_object after
the _cap member threw an exception, the object was not dissolved from
the entrypoint although the Rpc_object vanished at this point. This was
because the call to 'manage()' happened in the initializer list (for the
_cap member instantiation). The destruction of the _cap member then did
not dissolve the object.

This first fix moves the call to 'manage()' into the constructor body
after the instantiation of all other members. A more sophisticated fix
would use some kind of 'Managed_object' life-time guard that manages an
object on construction and dissolves on destruction.

7ac32ea60c libc: support for ioctls via ioctl directory
This patch introduces a new scheme of handling ioctl operations that
maps ioctls to pseudo-file accesses, similar to how the libc maps socket
calls to socket-fs operations.

A device file can be accompanied with a (hidden) directory that is named
after the device file and hosts pseudo files for triggering the various
device operations. For example, for accessing a terminal, the directory
structure looks like this:

  /dev/terminal
  /dev/.terminal/info

The 'info' file contains device information in XML format. The type of
the XML node corresponds to the device type. E.g., If the libc receives
a 'TIOCGWINSZ' ioctl for /dev/terminal, it reads the content of
/dev/.terminal/info to obtain the terminal-size information. In this
case, the 'info' file looks as follows:

  <terminal rows="25" columns="80/>

Following this scheme, VFS plugins can support ioctl operations by
providing an ioctl directory in addition to the actual device file.

Internally, the mechanism uses the 'os/vfs.h' API to access pseudo
files. Hence, we need to propagate the Vfs::Env to 'vfs_plugin.cc' to
create an instance of a 'Directory' for the root for the VFS.

5ab1505d43 file system: enhanced file status info
This patch extends the 'File_system::Status',
'File_system::Directory_entry', and the related 'Vfs' types with
the following additional information:

- Distinction between continuous and transactional files (Node_type)
  (issue #3507)
- Readable, writeable, and executable attributes (Node_rwx),
  replacing the former 'mode' bits
  (issue #3030)

The types 'Node_rwx', 'Node_type' are defined twice,
once for the VFS (vfs/types.h) and once for the 'File_system'
session (file_system_session/file_system_session.h).
Similarly, there is a direct correspondance between
'Vfs::Directory_service::Dirent' and 'File_system::Directory_entry'.

This duplication of types follows the existing pattern of keeping the
VFS and file-system session independent from each other.

eefe91ee41 depot_download_manager: no mtime update in extract
With the added modification-time support in the libc, the extract tool
requires a timer session, which is not plausible for the purpose of the
program.

This behavior stems from the fact that the libc implicitly writes the
mtime when closing a written file. For this update, it implicitly calls
'clock_gettime', which in turn initializes the timer subsystem within
the libc (creating a timer session).

For the extract tool, the implicitly updated mtime is useless because
the extract tool overwrites this modification time with the mtime stored
in the archive anyway. However, the dependency from a timer service
remains.

This patch explicitly disables the libc's implicit updating of the
file-modification when closing a written file.

94b63924ed noux: add time modification
... and set initial time by using RTC session.

Up to now Noux used a monotic clock whose initial start value always
was '0' (which correlates to the start of the UNIX epoch) to provide
a notion of time. In addition it is now possible to use the RTC
session to set the initial value for use cases where having a proper
real-world time matters.

To use the RTC session the 'rtc' attribute of the '<config>' node
must be set to 'yes'. Thereby the session becomes a mandatory
dependency as Noux will not start without it.

648bcd1505 libc: unify use of namespaces
This patch unifies the patterns of using the 'Genode' and 'Libc'
namespaces.

Types defined in the 'internal/' headers reside in the 'Libc'
namespace. The code in the headers does not need to use the
'Libc::' prefix.

Compilation units import the 'Libc' namespace after the definition of
local types. Local types reside in the 'Libc' namespace (and should
eventually move to an 'internal/' header).

Since the 'Libc' namespace imports the 'Genode' namespace, there is
no need to use the 'Genode::' prefix. Consequently, code in the
compilation units rarely need to qualify the 'Genode' or 'Libc'
namespaces.

There are a few cases where the 'Libc', the 'Genode', and the global
(libc) namespaces are ambigious. In these cases, an explicit
clarification is needed:

- 'Genode::Allocator' differs from 'Libc::Allocator'.
- 'Genode::Env' differs from 'Libc::Env'.
- Genode's string functions (strcmp, memcpy, strcpy) conflict
  with the names of the (global) libc functions.
- There exist both 'Genode::uint64_t' and the libc'c 'uint64_t'.

bf92232698 libc: split task.cc into multiple files
This patch is the first step of re-organizing the internal structure of
the libc. The original version involved many direct calls of global
functions (often with side effects) across compilation units, which
made the control flow (e.g., the initialization sequence) hard to
follow.

The new version replaces those ad-hoc interactions with dedicated
interfaces (like suspend.h, resume.h, select.h, current_time.h). The
underlying facilities are provided by the central Libc::Kernel and
selectively propagated to the various compilation units. The latter is
done by a sequence of 'init_*' calls, which eventually will be replaced
by constructor calls.

The addition of new headers increases the chance for name clashes with
existing (public) headers. To disambiguate libc-internal header files
from public headers, this patch moves the former into a new 'internal/'
subdirectory. This makes the include directives easier to follow and the
libc's source-tree structure more tidy.

There are still a few legacies left, which cannot easily be removed
right now (e.g., because noux relies on them). However, the patch moves
those bad apples to legacy.h and legacy.cc, which highlights the
deprecation of those functions.

6894ced63b libc: execve
This patch implements 'execve' in Genode's libc.

The mechanism relies on the dynamic linker's ability to replace the
loaded binary while keeping crucial libraries - in particular the libc -
intact. The state outside the libc is wiped. For this reason, all libc
internal state needed beyond the 'execve' call must be allocated on a
heap separate from the application-owned malloc heap. E.g.,
libc-internal file-descriptor objects must not be allocated or refer to
any memory object allocated from the malloc heap.

66d5359d75 ldso: heuristics for libs needed during execve
The allocation of regions within the linker area is normally left to the
best-fit 'Allocator_avl', which happens to populate the linker area
starting with the binary followed by all loaded libraried with no gaps
in between.

When replacing the binary during execve, however, we need to ensure that
the new binary does not conflict with any library that stays resident
during execve. This patch tweaks the linker's region allocation scheme
such that these libraries are placed at the end of the linker area.

fa48054959 ldso: Dynamic_linker::respawn mechanism
This patch extends the interface of the dynamic linker with the ability
to replace the running binary executable by another one. It is
designated for the implementation of execve. The interface consists of
two new functions.

'Dynamic_linker::keep' marks the specified shared object as unloadable.
This can be used to pin a set of libraries (i.e., the libc) within the
local address space while replacing the binary and other higher-level
libraries.

'Dynamic_linker::respawn' unloads the current binary, loads the one
specifed as first argument, and looks up the entry point symbol of the
new binary, which would be "main" for POSIX programs.

In addition to implementing the new interface, the patch adjusts the
linker at various places that previously assumed the binary to be
constant over runtime.

3c6fe6e741 ldso: statically allocate initial heap block
This patch enables the fork.run script to run on base-linux. It should
be regarded as an interim solution, however, because the randomization
performed by the Linux kernel may still - by chance - produce a
situation where one of the libc's malloc heap regions intersects with
another dataspace dynamically attached to the child.

The better solution would be to make the 'Region_map_mmap'
implementation not depend on the kernel's allocation policy by using a
locally implemented allocator.

65f75589e9 libc: configurable initial FDs
The libc already supports the configuration of 'stdin', 'stdout', and
'stderr' using '<libc>' config attributes. This patch equips the libc
with the additional ability to pre-initialize any other file descriptor.
A file descriptor is configured as follows:

<config>
  ...
  <libc ...>
    <fd id="3" path="/dev/log" writeable="yes" readable="no" seek="10"/>
    ...
  </libc>
</config>

Furthermore, this patch moves the FD initialization code from the VFS
plugin to the libc kernel initialization because opening the FDs
depends on 'malloc' ('strdup'), which should not be used at early
'Libc::Kernel' initialization time.

command, but it may potentially also occur in other circumstances.

ce149397ec acpica: retrieve static battery info only once
On Fujitsu S936, evaluating the _BIF method on each battery-info update
successively increased the RAM usage, while  _BST (dynamic battery
status) and _STA (generic status) did not show this behavior. Therefore
this commit retrieves only dynamic information periodically (resp. on
SCI IRQ). Now, acpica hast static RAM usage in idle state for 24+ hours.

The root cause for the increased RAM usage is still shady. While it
could just be normal that it grows until a certain yet unknown limit,
there may also be memory leak in contrib code or some strange AML on the
designated notebook.

c7e79030dd sculpt: limit rate of depot queries
The triggering of a new depot query can happen more than once per
activation of the sculpt manager if multiple conditions call for updated
information about the depot. When this happens, the depot-query
component produces intermediate results, which are not consumed by the
sculpt manager. By deferring depot queries for a few milliseconds, we
avoid such intermediate queries, relieving the workload of the
depot-query component at system boot time.

7e7eff0eb7 window layouter: reduce snap-back artifact
When resizing windows of clients that respond very slowly to resize
requests, the window's size sometimes snapped back to its original size
immediately after finishing the drag operation.

The problem was caused by the interplay of the layout rules (obtained
via the 'rules' ROM, generated by the 'rules' report) and the
temporary interactive state that occurs during drag operations.
The rules are updated only at the time of releasing the button to keep
the overhead while dragging the window low. However, when releasing the
mouse, the (now outdated) rules kicked back into effect, triggering
resize requests for the window to its old size.

The patch solves this problem by decoupling the dragged state of a
window from the physical release of the button. The button release
triggers a transition from a DRAGGING to a SETTLING state and programs
a timer. In the SETTLING state, the windows behave as in DRAGGING state,
giving the interactive geometry precedence over the rules-dictated
geometry. During this state, further responses of window-resize requests
may come in and are handled like dragging was still in progress. After a
timeout, however, the current window layout is conserved as a new rules
report and the state goes back to IDLE.

For clients that takes a very long time (in particular, VirtualBox when
resizing the desktop, which takes sometimes multiple seconds), the
snap-back artifact can still occur, but the effect is reduced.

dec2d897c3 themed_decorator: fix jumping windows
The decorator's detection of the hovered window element was inaccurate,
which resulted in "jumping" windows in some situations, ultimately
caused by a combination of three different mechanisms.

First, when moving the pointer into the area of a window, the decorator
would detect the hovering of the left border whenever the distance of
the pointer from the border was less than the half of the theme texture
(e.g., 64x64 pixels for the default theme). However, if the left border
margin is set to a small value (e.g., 1), there is an overlap of the
sensitive resize border area and the content. Hence, chances were quite
high that - when moving the pointer from the left into the window - the
hover report would contain the hovering of the left border.

Second, the window manager tries to hide pointer movements from the
decorator if possible. It informs the decorator of the pointer position
if any decoration is hovered or if a new window is hovered. But it does
not expose pointer movements within a window to the decorator. For this
reason, the decorator would not update the hover report as long as the
pointer stays within a once hovered window. In the situation described
above, the hover report would still contain the stale information about
the hovering of the left resize border.

Third, when the user clicks on the window, the decorator examines the
most recent hover report and - in the situation described above - finds
the left border hovered. Consequently, it initiates a window-drag
operation. While resizing the window with the left border, the window
layouter pins the right border of the window to its current position.
All window-size changes of the client will be applied towards the left
(dragged) border. In the case of the top view, which continuously
resizes the window by itself, the window would "jump". In reality, it
actually tries to respond an interactive resize operation. The window
layouter cannot guess that the client is not responding to window
layouter's resize request but is acting independently.

This patch fixes the jumping window problem for the case where the
pointer hovers the overlapping area of the resize border and the
content. However, when trying the to interactively resize the top window
via the bottom-left corner, the "jumping" can still be observed.

fe5ada85cb depot_autopilot.run: max nr of tests per boot
Some platforms (sel4 imx6/imx7) cannot manage to execute all tests in a single
boot. Thus, we re-boot them periodically after a given maximum number of tests
to avoid that arbitrary tests always fail due to the long uptime and not due to
the tests themselves.

If the maximum number of tests is set to 0, no limit is applied.

62232f9a35 fs_rom: retry watching a path element after watching its parent dir
If a path element cannot be watched because it does not exist yet, the next
available parent directory is watched to detect the creation of the missing
path element. If a missing path element got created just between the failed
watch request for the element and the successful watch request for its parent
directory, the creation of the path element could remain unnoticed.

With this commit, 'fs_rom' tries to watch a path element again if the watch
request for its parent directory was successful.

ed0d76552b Relax timing requirements in lazy timer test
The lazy-timer test depends on the faster-timer handler to be executed
before the fast timeout occurs, which was pretty hard to achieve on Qemu
and a busy host machine. Therefore, I increased the fast-to-faster
timeout ratio from 50/25 ms to 200/25 ms and set the test runtime to
4000 ms.

ae7fbd6b1a terminal: modernize color palette

      <color index="8" value="#101010"/> <!-- bright black stands out a bit -->
    </palette>
  </config>

Note, the old (undocumented) <color index="..." bg="..."> configuration
scheme is no longer supported.

Also, this commit adds a pleasing default palette that ensures

Since gcc 8.3.0 generates SSE instructions into kernel code, the
kernel itself may raise FPU exceptions and/or corrupt user level FPU
contexts thereby. Both things are not feasible, and therefore, lazy FPU
switching becomes a no go for base-hw because we cannot avoid FPU
instructions because of the entanglement of base-hw, base, and the tool
chain (libgcc_eh.a).

d223539165 wifi_drv: ignore socket flags on socket creation
The libc features support for SOCK_CLOEXEC now which gets set via

actual type, i.e. if it is SOCK_RAW, just ignore the flags.

a1e70b9ba4 kernel: differentiate board-specific components
Components like kernel, core, and bootstrap that are built for a
specific board need to reside inside the same architectural dependent
build directory. For instance there are sel4, foc, and hw kernel builds
for imx6q_sabrelite and imx7d_sabre, which have to reside inside the same
arm_v7 build directory.
This commit names those components explicitely, and adapts the run-tool to it.

the report. However, this doesn't reset the BDF counter used to iterate
over the devices. This results in starting the new report after the PCI
device that triggered the report buffer overflow. This commit fixes the
issue by putting the BDF counter initialization inside the lambda
function used to generate the report.

784206c85c block_session: new client-side API
This patch equips the 'Block::Connection' with a framework API for the
implementation of robust block-session clients that perform block I/O in
an asynchronous fashion.

An application-defined 'JOB' type, inherited from 'Connection::Job',
encapsulates the application's context information associated with a
block operation.

The lifecycle of the jobs is implemented by the 'Connection' and driven
by the application's invokation of 'Connection::update_jobs'. The
'update_jobs' mechanism takes three hook functions as arguments, which
implement the applications-defined policy for producing and consuming
data, and for the completion of jobs.

593e971121 block_session: SYNC and TRIM as async operations
This patch removes the blocking Block::Session::sync RPC function and
adds the asynchronous operations SYNC and TRIM to the block session's
packet-stream interface.

Even though the patch adjusts all block components to the interface
change, the components keep the former blocking handling of sync
internally for now because of the design of the 'Block::Driver'
interface. This old interface is not worth changing. We should instead
migrate the block servers step by step to the new
'Block::Request_stream' API.

e058adc4fe block_session: add client-defined request tag
The new request tag allows a block-session client to uniquely correlate
acknowledgements with outstanding requests. Until now, this was possible
for read and write operations by taking the value of the request's
packet-stream offset. However, SYNC and TRIM requests do not carry any
packet-stream payload and thereby lack meaningful offset values. By
introducing the notion of a 'tag', we can support multiple outstanding
requests of any type and don't need to overload the meaning of the
'offset' value.

a39474a245 block-request stream: split Operation from Request
This patch splits the 'Request' definition into smaller types that are
suitable for the client-side API too.

The new 'Operation' type comprises the block operation's type (opcode)
and the operation's arguments (block number, block count).
The former 'Request::operation_defined' is now 'Operation::valid'.
The 'Request' aggregates an 'Operation', which changes its object
layout.

Note that this commit relaxes the bit-precise definition of 'Request' to
facilitate the use of 'unsigned long' where appropriate, in particular
for the request tag (which should correspond to an 'Id_space::Id'). The
originally bit-precise definition was pursued to allow the sharing of
the 'Request' type between SPARK and C++ code. However, it turns out
that defining a native type in each language and a (set of) converting
constructors is a more natural approach.

bbe3ee8dc5 block_session: server-defined payload alignment
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.

First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.

Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.

The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.

At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).

Replace the use of handle lists in plugins with handle queues, this

These changes replace the use of the Post_signal_hook from all VFS

occur during I/O signal dispatch and use an Io_progress_handler at its
entrypoints to defer response until after signal dispatching.

vendor is Intel. Hopefully we do not render HDA on real machines
useless with this changes (so far I have not encountered one).

4b0b4928f5 tool/depot: rm binary archives if versions collide
This patch handles version collisions of binary archives. If a binary
archive for an (automatically) updated src-archive version already
exists in the depot, the extract tool removes the binary archive because
its existing content may stem from another src content (a version from a
different topic branch). This ensures that the new version is always
built, not skipped, when 'UPDATE_VERSIONS=1 REBUILD=' is specified.

aeb7e7cd7c sculpt manager: prevent double destruction
The '_currently_constructed' pointer caches the information about which
'Launched_child' is currently configured in the menu. When discarding
the runtime (e.g., when un-using a file system) at this point, this
cached pointer was not invalidated while all 'Launched_child' objects
would be freed (including the currently constructed one). On the next
attempt to construct a new child, the sculpt manager attempted to
destruct the 'Launched_child' referred by the (now outdated)
'_currently_constructed' again.

806dc5de36 window layouter: improved maximize handling
It turns out that the commit "window layouter: allow floating apps to
resize" interplays badly with the interactive toggling of the maximize
state of windows. In contrast to the window geometry and stacking, which
is always updated through the rules-feedback mechanism, interactive
changes of the maximize state omitted this loop and instead took a local
shortcut. Because of this shortcut, the maximized geometry eventually
ended up as window size in the window's assign rule. So unmaximizing the
window failed to revert the geometry to its original state.

This patch removes this inconsistency. The maximize state adheres to the
official chain of commands through the rules mechanism now. The state is
now maintained internally without affecting the window's geometry and is
evaluated while generating the window layout only.

As a minor loosely related improvement, this patch prevents the
highlighting of resize handles for non-resizable windows.

905da4b0cc menu_view: fade between button styles
The button widget already supported an animated transition between
hovered and unhovered states. This patch generalizes the mechanism to
allow animated transitions between arbitrary button states, including
style changes.

This way, the fade-out of non-TCB components in Sculpt CE happens not
abruptly but smooth.

116bfab449 icon_painter.h: customizable pixel transfer
This patch makes the application of color/alpha from the icon's texture
to the target surface customizable by replacing the formerly built-in
'_transfer_pixel' function by calls to the new 'Pixel_rgba::transfer'
interface.

ebd9f36b0d os: Pixel_rgba::transfer interface
The new 'transfer' function interface defines how pixel/alpha values
sampled from texture are applied to a destination pixel, similar to the
role of a fragment shader in GPU-based rendering. The transfer function
can be customized by defining custom pixel types, which may be (but
don't need to be) derived from 'Pixel_rgba'.

b00e1f4e4b menu view: position widgets initially at (0, 0)
The default 'Rect' constructor constructs an invalid rectangle where the
p1 coordinates are lower than the p2 coordinates. In particular, p1 is
set to (1, 1). The 'Widget' implementation uses the points individually
as input into the 'Animated_rect' mechanism. This way, widgets end up
being positioned at (1, 1) initially and are moved to (0, 0) once the
first layout update is applied. By explicitly initializing the
'_geometry' to (0x0+0+0), we avoid this initial artifact.

669aed0ac0 sculpt: don't reset hover on click on '+' menu
When entering/leaving sub menus of Sculpt's '+' menu, some parts of the
menu sometimes remain unchanged, in particular the back button.
Originally, a click would reset the hovering on clicks in the
expectation that any click would eventually result in a completely new
situation where the old hovering information does not make sense and
would only (potentially) confuse the menu. But this was apparently
overzealous. With the patch a once hovered back button stays hovered
even when actitivated and the back button of the upper-level menu
happens to stay under the current pointer position.

014e800e8a menu view: immediate hover update on dialog change
This patch improves the hover handling in situations where the dialog
changes under the pointer. Previously, hover changes were reported
as response to user input only, which failed to cover this case. This
became a problem with Sculpt CE's '+' menu, which changes on the fly
when entering/leaving sub menus.

The patch also cleanly separates the hover handling from the focus
handling. Originally, the hovering was reset when the menu view got
unfocused. In situations like Sculpt's '+' menu where the menu view
receives a transient focus only while clicked and gets unfocused on the
button-release event (aka clack), each clack would invalidate the hover
information until a new input event comes in.

Finally, the patch introduces the clear distinction between situations
where the entire dialog is hovered or not. Previously, this state was
somehow implicitly kept by issuing an invalid hover report whenever a
leave event was observed.

a61c5b6be3 wm: move virtual pointer pos on window movement
When a window is moved, the virtual pointer position must be updated,
taking the changed input coordinate into account. This patch propagates
such changes via absolute motion events to the client.

Without this patch, Sculpt CE's '+' menu wouldn't update the hovered
item correctly when entering/leaving sub menus (which happen to trigger
the repositioning of the menu on screen).

57fd4e9148 Add Io_progress_handler to Entrypoint interface
The "schedule_post_signal_hook" method of the Genode::Entrypoint class
is problematic because the signal hook can be scheduled and replaced
multiple times during the signal dispatch cycle. Add an alternative to
this method with "register_io_progress_handler" and the "Post_signal_
hook" class with "Io_progress_handler". The difference being an
"Io_progress_handler" may be registered once during the lifetime of an
entrypoint to prevent arbitrary libraries from replacing a pending hook.

The "register_io_progress_handler" remains as a deprecated API, and is
now invoked for every I/O signal received and only for I/O signals
rather than for any signal.

cd244c2077 sculpt: don't install any index by default
When buiding the sculpt image, the sculpt.run script used to integrate
the current version of the index of the 'depot_user' into the boot
image. At runtime, when the Sculpt partition is selected for "use" this
index - along with the 'pubkey' and 'download' files of the known
depot users - is written to the Sculpt partition.

This has the undesirable effect that a later version of the index
(published some time after the sculpt image was created) would always be
overwritten by the outdated index shipped with the boot image.

The built-in default index was actually a stop-gap solution needed
during the development of Sculpt CE, introduced when the downloading of
index files was not yet supported. Now, with the working download
mechanism, it is no longer needed. Hence, this patch removes the default
index from the sculpt image.

b7f5aae64a sculpt: don't constrain '+' menu to avail space
Sculpt used to restrict the size of leitzentrale windows to the screen
area that is not obstructed by the menu and log. This is useful for the
runtime view and the inspect window. However, the menu should be allowed
to use the entire screen because it overlays the other content.

Before this patch, the menu wouldn't be displayed completely on small
resolutions (e.g., 1024x768 when using the VESA driver) because the log
at the bottom of the screen imposed the size constraint on the menu.
With the patch, the menu is able to overlay the log window.

ac68073ffc depot_download: support downloading index files
With this commit, the 'installation' input of the depot-download
subsystem accepts <index> nodes in addition to <archive> nodes. Each
index node refers to one index file specified via the 'path' attribute.

This commit also improves the tracking of failure states. Once an
installation job failed (due to a download of verification error),
it won't get re-scheduled. In the past, such failure states were not kept
across subsequent import iterations, which could result in infinite
re-attempts when an installation contained archives from multiple users.
The the progress of the download process is now reflected by the
"progress" attribute on the download manager's state report, which
allows the final report to contain the list of installed/failed archives
along with the overall progress/completed state. The detection of the
latter is important for the sculpt manager for reattempting the
deployment of the completed packages.

The patch enhances the depot_download.run script to stress the new
abilities. In particular, the scenario downloads a mix of index files
(one present, one missing) and archives, from two different depot users
(genodelabs and nfeske).

2cf4e5a6de hw: fix regression of smp kernel initialization
In commit "hw: improve cross-cpu synchronization" the implicit safe
initialization of the global kernel lock gets unsafe.
It is a static object, which is protected by the cxx library regarding
its initialization. But our cxx library uses a Genode::semaphore in
the contention case of object construction, which implicitly leads
to kernel syscalls for blocking the corresponding thread. This behaviour
is unacceptable for the kernel code.
Therefore, this fix guards the initialization of the kernel code with
a simple static boolean value explicitely.

d3d6b643f1 wm: shape report interception mechanism
This patch simplifies the propagation of pointer shapes from
window-manager clients to the pointer. The "shape" report is routed to
the wm server, which, in turn, reports it to the pointer. This way, the
pointer can easily correlate the label of the application's "shape"
report with the label of the application's Nitpicker session. The
formerly used manual rewriting of the "shape" label is not needed
anymore.

Since the wm server provides a "Report" service now, its <provides>
declaration must cover "Report" in addition to "Nitpicker" to avoid
runtime error messages. Vice versa, the wm is now expected to request
"shape" reports, which should be routed to the pointer (using the
'label_last' routing attribute).

5ed5fddb7c base/os: remove deprecated APIs
This commit removes APIs that were previously marked as deprecated. This
change has the following implications:

- The use of the global 'env()' accessor is not possible anymore.
- Boolean accessor methods are no longer prefixed with 'is_'. E.g.,
  instead of 'is_valid()', use 'valid()'.
- The last traces of 'Ram_session' are gone now. The 'Env::ram()'
  accessor returns the 'Ram_allocator' interface, which is a subset of
  the 'Pd_session' interface.
- All connection constructors need the 'Env' as argument.
- The 'Reporter' constructor needs an 'Env' argument now because the
  reporter creates a report connection.
- The old overload 'Child_policy::resolve_session_request' that returned
  a 'Service' does not exist anymore.
- The base/printf.h header has been removed, use base/log.h instead.
- The old notion of 'Signal_dispatcher' is gone. Use 'Signal_handler'.
- Transitional headers like os/server.h, cap_session/,
  volatile_object.h, os/attached*_dataspace.h, signal_rpc_dispatcher.h
  have been removed.
- The distinction between 'Thread_state' and 'Thread_state_base' does
  not exist anymore.
- The header cpu_thread/capability.h along with the type definition of
  'Cpu_thread_capability' has been removed. Use the type
  'Thread_capability' define in cpu_session/cpu_session.h instead.
- Several XML utilities (i.e., at os/include/decorator) could be removed
  because their functionality is nowadays covered by util/xml_node.h.
- The 'os/ram_session_guard.h' has been removed.
  Use 'Constrained_ram_allocator' provided by base/ram_allocator.h instead.

924e5c54eb core: fix RM-session upgrade mechanism
This is a follow-up commit of "base/core: use references instead of
pointers". Because the 'Rm_root::_upgrade_session' implementation
lacked the 'override' keyword, my overzealous change of the pointer
argument went unnoticed.

This commit fixes the depot_rom (cached_fs_rom) failure in Sculpt.
When cached_fs_rom attempted to create a new managed dataspace while the
RM session quota was depleted, it tried to upgrade the session (via
Rm_connection::create). However, the upgraded resources never reached
the actual session because the default 'Root_component::_upgrade_session'
was called instead of 'Rm_root::_upgrade_session'.

aa66b5d62f base: remove dependency from deprecated APIs
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.

The most prominent changes are:

- Removing the use of base/printf.h

- Removing of the log backend for printf. The 'Console' with the
  format-string parser is still there along with 'snprintf.h' because
  the latter is still used at a few places, most prominently the
  'Connection' classes.

- Removing the notion of a RAM session, which does not exist in
  Genode anymore. Still the types were preserved (by typedefs to
  PD session) to keep up compatibility. But this transition should
  come to an end now.

- Slight rennovation of core's tracing service, e.g., the use of an
  Attached_dataspace as the Argument_buffer.

- Reducing the reliance on global accessors like deprecated_env() or
  core_env(). Still there is a longish way to go to eliminate all such
  calls. A useful pattern (or at least a stop-gap solution) is to
  pass the 'Env' to the individual compilation units via init functions.

- Avoiding the use of the old 'Child_policy::resolve_session_request'
  interface that returned a 'Service' instead of a 'Route'.

2e1e7b8270 recipes/src/base-hw-muen: add static ACPI ROM
As we don't execute the acpi_drv on Muen, we have to supply a static
'acpi' info as boot module. This is normally done by the
base/run/platform.inc include. However, when using base-hw-muen kernel
from a depot archive - as done by modern run scripts like
depot_download.run - the platform.inc magic is not applied.

This patch enhances the src archive of base-hw-muen with a mechanism
that creates a pre-defined acpi info at the bin directory via an
artificial src/acpi/target.mk file. This way, the static acpi ROM ends
up as boot module when importing the base-hw-muen archive into a
run script.

6b289a1423 base/core: use references instead of pointers
This patch replaces the former prominent use of pointers by references
wherever feasible. This has the following benefits:

* The contract between caller and callee becomes more obvious. When
  passing a reference, the contract says that the argument cannot be
  a null pointer. The caller is responsible to ensure that. Therefore,
  the use of reference eliminates the need to add defensive null-pointer
  checks at the callee site, which sometimes merely exist to be on the
  safe side. The bottom line is that the code becomes easier to follow.

* Reference members must be initialized via an object initializer,
  which promotes a programming style that avoids intermediate object-
  construction states. Within core, there are still a few pointers
  as member variables left though. E.g., caused by the late association
  of 'Platform_thread' objects with their 'Platform_pd' objects.

* If no pointers are present as member variables, we don't need to
  manually provide declarations of a private copy constructor and
  an assignment operator to avoid -Weffc++ errors "class ... has
  pointer data members [-Werror=effc++]".

This patch also changes a few system bindings on NOVA and Fiasco.OC,
e.g., the return value of the global 'cap_map' accessor has become a
reference. Hence, the patch touches a few places outside of core.

f9373b4430 base: new Allocator_avl::construct_metadata method
The new method allows for the construction of a meta-data object inside
the reserved space of the allocator's meta data. It thereby alleviates
the need to copy the meta data object (via the assignment operator) as
done by the traditional 'metadata' setter method. This, in turn, allows
one to use non-copyable objects (like objects with constant member
variables) as meta data.

This patch moves the removal of the signal context from the

The former 'Genode::Timed_semaphore' mechanism is moved to the private

there are now two private copies of 'timed_semaphore.h'. This should be
regarded as an interim step until the use of this mechanism is removed
from both users.

This patch also cleans up the mechanism from legacy Genode API calls and
global side effects (alarm-thread singleton). The test/timed_semaphore
is now located at the libports repository as it now tests a mechanism of
the libc. The former timed_semaphore library is no more.

bf62d6b896 Move timer from os to base repository
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.

Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.

Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.

f0842a27c5 depot_autopilot: provide repeat mode
Adds an config attribute to the Depot Autopilot component:

:<config repeat>:

  Can be one of

    "false"         - process the given test list only once,
    "until_forever" - endlessly repeat processing the given test list,
    "until_failed"  - repeat processing the given test list until it fails.

Adds an environment variable to the Depot Autopilot Run script:

:TEST_REPEAT:

  Same as the <config repeat> attribute of the Depot Autopilot.

This is useful when having to debug very sporadic errors during one test
or a series of tests.

4f316cffbc init: update state reports on heartbeat responses
Init's state reports are updated whenever an interesting part of init's
internal state changes (e.g., when sessions are established, or when
children are started/removed). However, until now, a change of a skipped
heartbeat counter was not taken as trigger for state-report updates.

In scenarios where no other intersting event happened, the last reported
state did no reflect the current heartbeat state. In particular, when
the last report was issued during the construction of a new child just
before the child became able to respond to heartbeat requests, the stale
report hinted at heartbeat problems that were just an initialization
artifact. This problem became visible on some Qemu platform where the
child startup takes a long time.

The patch tracks the observed skipped-heartbeat counter and triggers a
report whenever the counter value changes.

The number of tests to run is the number of test package-archives minus the

It helps the surrounding test infrastructure to ensure that, for instance, a
result graph always reflects the same total number of tests, even though there
is a sporadic problem with booting the platform.

8e13b376b0 hw: improve cross-cpu synchronization
This commit addresses several multiprocessing issues in base-hw:

* it reworks cross-cpu maintainance work for TLB invalidation by
  introducing a generic Inter_processor_work and removes the so
  called Cpu_domain_update
* thereby it solves the cross-cpu thread destruction, when the
  corresponding thread is active on another cpu (fix #3043)
* it adds the missing TLB shootdown for x86 (fix #3042)
* on ARM it removes the TLB shootdown via IPIs, because this
  is not needed on the multiprocessing ARM platforms we support
* it enables the per-cpu initialization of the kernel's cpu
  objects, which means those object initialization is executed
  by the proper cpu
* it rollbacks prior decision to make multiprocessing an aspect,
  but puts back certain 'smp' mechanisms (like cross-cpu lock)
  into the generic code base for simplicity reasons

such a window, which is unintuitive. The new version applies the

a2bdcc68c2 Throw exception for invalid packets at packet streams
Some application code is dereferencing the pointer returned by
'packet_content' at packet streams without checking that it is valid.
Throw an exception rather than return a null pointer, except for
zero-length packets, which have somewhat implicit invalid content and
that we believe to be properly handled in all current cases.

The client-side of a packet stream cannot take corrective action if the
server-side is sending packets with invalid content, but the servers
that provide packet streams should catch this exception to detect
misbehaving clients.

6c70a51d28 sculpt_manager: improved popup toggling
In a corner case, the toggling of the popup menu entered a state
where the menu could not be opened anymore by the user. Specifically
the following input sequence triggered this problem.

1. The user opens the menu
2. The user clicks on the menu and holds the button
3. While holding the button, the user moves the pointer to the
   outside of the popup (e.g., to the '+' button)
4. The user releases the button.

In this situation, the popup is closed but the hover information for the
popup contains still the original clicked-on item. Hence, all subsequent
clicks on the '+' appear as both a click on the '+' (opening the popup)
and a click on the "hovered" popup entry (closing the popup).

The patch explicitely clears the popup's hover information when closing
the popup.

c60604062c decorator: improve robustness of window restacking
This patch improves the detection of new appearing top-most windows.
Such a window should prompt the decorator to bring the corresponding
nitpicker view(s) to the front of the view stack. The original
implementation relied on hints provided by the layouter (the 'topped'
attribute). With the patch, the decorator tracks the top-most window by
itself, which improves the robustness.

As a second improvement, the patch defers the destruction of windows to
the point when all other window operations are completed. This hides
intermediate states when replacing one window by another in one step,
which is typical for console-like scenarios. Hence, this patch should
eliminate flickering artifacts when switching from one virtual console
to another.

The code in 'cdefs.h' does not check if the '__always_inline' is already

3e31e2ba53 VFS LwIP: blocking TCP write
Block and loop until application writes are sent or buffered in their
entirety. Do not call "tcp_output" directly, LwIP calls this procedure
internally and calling it again appears to disrupt the LwIP TCP state
machine.

9ca214eee8 usb: quickfix pointer-emulation for touch screen
Move button-event reporting behind pointer-position update.

This is just a quickfix to restore correct pointer emulation with
dde_linux usb_drv. It does not change usb_hid_drv because the approach
is a questionable workaround of the current input event handling, which
reports events promptly on occurrence of inputs events and ignores
synchronization events completely. The original contrib code reported
the button press before absolute x and y positioning followed by a sync
event.

7d641d5f1f base: add Reconstructible::conditional method
The new 'conditional' method simplifies the typical use case for
'Constructible' objects where the constructed/destructed state depends
on a configuration parameter. The method alleviates the need to
re-implement the logic again and again.

The patch also removes the 'Reconstructible' constructor arguments
because they are unused.

304cb290d9 nic_router: rework quota accounting
* Account all RAM/CAP quota of a session except quota for metadata used in
  core. The latter is considered when asking if a session can afford to make
  an operation but it does not get accounted to always be able to pay back all
  quota when a session closes. The general accounting mechanism is moved from
  atop of the allocators down to the level of RAM/RM session operations.
* report statistics about session objects and quota if <report stats="yes"
  quota="yes"/> is configured. (default is yes if <report> is present)

bd77bb41df nic_router: improve handling of TCP termination
Like suggested by RFC 2663, reprogram the dissolve timeout of a TCP link
state to 2 times the maximum segment lifetime (by default 1 minute) when
receiving a matching packet with the FIN flag set, or with the ACK flag
set to acknowledge a FIN of the remote side.

Mark a link state as closed (no further reprogramming of the dissolve
timeout) and set the dissolve timeout to 2 times the maximum segment
lifetime when receiving a packet with the RESET flag set.

d6c6549354 nic_router: destroy links on insufficient resource
If the NIC router has insufficient CAP or RAM quota for the creation of
a state object for an interface, it tries to destroy a certain amount of
existing state objects of this interface to free resources. Afterwards,
it retries handling the current packet once. If it does fail again, the
router drops the packet.

caused unnecessary characters to remain in the out buffer for each
reverted node.

:Tiled window manager:
At Genode Labs, we pursue the goal to shape Genode into an general-purpose
operating system suitable for productive work. The feature set needed to
achieve this goal largely depends on the tools and applications daily used by
the Genode engineers. As one particularly important tool for being highly
productive, we identified a tiled user interface. Currently, all developers
at Genode Labs embrace either the Ion3 window manager or the tiled Terminator
terminal emulator. Hence, we desire to have a similar mode of user
interaction on Genode as well. The goal of this challenge is to identify the
most important usage patters and the implementation of a tiled GUI that
multiplexes the framebuffer into a set of tiled and tabbed virtual
framebuffers.
Related to this work, the low-level 'Framebuffer' and 'Input' interfaces
should be subject to a revision, for example for enabling the flexible change
of framebuffer sizes as needed by a tiled user interface.

:Xlib compatibility:
Developments like Wayland notwithstanding, most application software on
GNU/Linux systems is built on top of the Xlib programming interface.
However, only a few parts of this wide interface are actually used today.
I.e., modern applications generally deal with pixel buffers instead of
relying on graphical drawing primitives of the X protocol. Hence, it seems
feasible to reimplement the most important parts of the Xlib interface to
target Genode's native GUI interfaces (nitpicker) directly. This would
allow us to port popular application software to Sculpt OS without
changing the application code.
:Bump-in-the-wire components for visualizing session interfaces:
Genode's session interfaces bear the potential for monitoring and
visualizing their use by plugging a graphical application
in-between any two components. For example, by intercepting block
requests issued by a block-session client to a block-device driver,
such a bump-in-the-wire component could visualize
the access patterns of a block device. Similar ideas could be pursued for
other session interfaces, like the audio-out (sound visualization) or NIC
session (live visualization of network communication).
The visualization of system behavior would offer valuable insights,
e.g., new opportunities for optimization. But more importantly, they
would be extremely fun to play with.

Linux process containers provide a mechanism to partition physical resources,
foremost CPU time, between Linux processes. This raises the interesting
question of whether this mechanism could be used for a proper implementation
of Genode's resource trading on Linux.
[http://lwn.net/Articles/236038/ - Process containers introduction...]
Even though there exists a great variety of ARM-based SoCs, Genode
primarily focuses on the NXP i.MX family because it is - in contrast
to most SoCs in the consumer space - very liberal in terms of
good-quality public documentation and reference code, and it scales
from industrial to end-user-facing use cases (multi-media).
The [https://puri.sm/products/librem-5/ - Librem5] project - with its
mission to build a trustworthy mobile phone - has chosen the i.MX family as
the basis for their product for likely the same reasons that attract us.
To goal of this work is bringing Genode to the Librem5 hardware.
For the Librem5 project, Genode could pave the ground towards new use cases
like high-security markets where a regular Linux-based OS would not be
accepted. For the Genode community, the Librem5 hardware could become an
attractive mobile platform for everyday use, similar to how we developers
use our Genode-based [https://genode.org/download/sculpt - Sculpt OS] on our
laptops.
System management
#################
:Remote management of Sculpt OS via Puppet:
[https://en.wikipedia.org/wiki/Puppet_(company)#Puppet - Puppet] is a
software-configuration management tool for administering a large amount
of machines from one central place. Genode's
[https://genode.org/download/sculpt - Sculpt OS] lends itself to such
an approach of remote configuration management by the means of the
"config" file system (for configuring components and deployments) and
the "report" file system (for obtaining the runtime state of components).
The project would explore the application of the Puppet approach and tools
to Sculpt OS.
Optimizations
#############
:Low-latency audio streaming:
Genode comes with an audio streaming interface called 'Audio_out' session.
It is based on a shared-memory packet stream accompanied with asynchronous
data-flow signals. For real-time audio processing involving chains of Genode
components, streams of audio data must be carried at low latency, imposing
constraints to buffer sizes and the modes of operation of the audio mixer and
audio drivers. The goal of this project is to create a holistic design of the
whole chain of audio processing, taking thread-scheduling into account. A
particular challenge is the mixed output of real-time (small buffer, low
latency) and non-real-time (larger buffer to compensate jitter, higher
latency) audio sources.

Genode OS Framework release 20.02 | 2020-02-28
##############################################
| With version 20.02, Genode makes Sculpt OS fit for running on i.MX 64-bit
| ARM hardware, optimizes the performance throughout the entire software stack,
| and takes the next evolutionary step of the user-facing side of Sculpt OS.
Without any doubt, Sculpt OS has been the driving motivation behind most
working topics featured by the new release. One particularly exciting line
of work is the enabling of Sculpt on i.MX-based 64-bit ARM hardware, which
touched the framework on all levels, from the boot loader, over the kernel,
device drivers, libraries, system management, up to the application level.
The work goes as far as supporting Sculpt OS as a hypervisor platform for
hosting Linux in a virtual machine.
As a second Sculpt-related development, we strive to make the user-visible
side of the operating system better approachable and more logical. With this
background, the current release comes with a profound redesign of the
administrative user interface of Sculpt OS. An updated downloadable system
image will follow soon.
Also related to Sculpt are an updated audio driver based on OpenBSD 6.6,
the support of virtual desktops, and performance optimization of the
Seoul virtual machine monitor on x86 hardware.
Regarding the framework API, the release introduces a new library for
building multi-component applications. It aims to bring the benefits of
Genode's unique security architecture from the operating-system level to the
application level.
These topics are only the tip of the iceberg. For the complete picture,
please consult the
[https:/documentation/release-notes/20.02 - release documentation of version 20.02...]
Road Map for 2020 | 2020-01-20
##############################
| In 2019, we will be concerned about dwarfing the barrier of entry into
| the Genode world.
Following the last year's leitmotif of "bridging worlds", we turn our
attention to the removal of the hurdles faced by aspiring developers and
users. During the annual road-map
[https://lists.genode.org/pipermail/users/2019-December/006987.html - discussion]
on our mailing list, we identified four tangible approaches towards that
goal. First, making Sculpt OS more user friendly. Second, reinforcing trust in
Genode by fostering the framework's high quality. Third, making the tooling
around Genode a joy to use. And finally, the illustration of Genode's
versatility in the form practical use cases.
Besides this overall theme, we plan to continue our commitment to the
NXP i.MX SoC family, revisit Genode's low-latency audio support, and
extend the cultivation of Ada/SPARK within (and on top of) Genode.
More background information about the new road map and a rough schedule are
presented at our official [https:/about/road-map - road-map page].
Genode OS Framework release 19.11 | 2019-11-28
##############################################
| Following this year's theme of "bridging worlds", Genode 19.11 adds the
| ability to use popular build tools like CMake for application development,
| introduces a new virtual-machine monitor for 64-bit ARM, and enhances
| POSIX compatibility. As another highlight, it features the first version
| of our custom block-device encrypter.
Block-device encryption is a feature often requested by users of our Sculpt OS.
Until now, we deliberately left this topic unaddressed because we felt that a
profound answer was beyond our expertise. However, during the past year, we
dived deep into it. The result is the prototype for a new block encrypter that
encrypts data but also protects integrity and freshness. For us, the
implementation of the encrypter is especially intriguing because - with about
7000 lines of code - it is Genode's first non-trivial component written in the
[https://en.wikipedia.org/wiki/SPARK_(programming_language) - SPARK]
programming language.
The second major addition is a new virtual machine monitor (VMM) for 64-bit
ARM platforms such as the NXP i.MX8. It leverages the
[https://genode.org/documentation/articles/arm_virtualization - proof of concept]
we developed in 2015 for ARMv7, which we pursued as a technology exploration.
In contrast, our aspiration with the new VMM is a product-quality solution.
In our [https://genode.org/about/road-map - road map] for 2019, we stated
the "bridging of worlds" as our overall theme for this year. On that account,
the current release moves the project forward on two levels. First, by
successively increasing the scope of POSIX compatibility, we reduce the
friction when porting existing application software to Genode. We managed
to bridge several gaps in our POSIX support that we considered as impossible
to cover some years ago. In particular, we identified ways to emulate certain
POSIX signals, ioctl calls, and fork/execve semantics. This way, popular
software such as bash, coreutils, or Vim can now be executed as regular
Genode components with no additional runtime environment (like Noux or a VMM)
required.
At a higher level, the current release introduces new tooling especially
geared at the development and porting of application software. Compared to
Genode's regular development tools, which were designed for whole-system
development, the new tool called Goa relieves the developer from the
complexity of Genode's custom build system and instead promotes the use of
popular commodity solutions like CMake.
These and more topics are described in the
[https:/documentation/release-notes/19.11 - release documentation of version 19.11...]
Genode OS Framework release 19.08 | 2019-08-28
##############################################
| Genode 19.08 puts emphasis on practical concerns ranging from
| keyboard layouts, over system-time management, to remote system
| administration. It also continues our commitment to the 64-bit ARM
| i.MX8 SoC, comes with Qt5 version 5.13, and improves POSIX compatibility.
The summer release of Genode addresses a variety of topics when using Genode
and Sculpt OS in practice. The confrontation with the real world prompted us
to develop new concepts for managing system time, keyboards layouts, and
copy-and-paste. For using Sculpt OS on the road, a new application VM for
accessing captive portals smoothes the experience of connecting to public WiFi
networks.
Besides the practical focus, the new release continues our commitment to the
64-bit ARM i.MX8 platform through new kernel support, device drivers, and test
coverage. Further topics include SMBIOS support for commodity PC hardware, a
new tracing tool, enhanced POSIX compatibility, and a major update of Qt5 to
version 5.13.
The complete picture is presented in the

Sculpt OS release 19.07 | 2019-07-09
####################################
| Version 19.07 of the Sculpt operating system improves overall performance
| and introduces copy and paste between terminals, virtual machines, and
| graphical applications.
The most prominent user-visible feature of Sculpt OS 19.07 is the ability
of copy and paste text between terminals, graphical applications, and
virtual machines. Our unique take on this feature is described in
a [https://genodians.org/nfeske/2019-07-03-copy-paste - dedicated article].
Under the hood, Sculpt 19.07 benefits from the massive infrastructure
improvements that came with
[https://genode.org/documentation/release-notes/19.05 - Genode 19.05],
yielding a smoother user experience compared to earlier versions.
The new release can be obtained from the
[https://genode.org/download/sculpt - Sculpt download page] and is
accompanied by updated
[https://genode.org/documentation/articles/sculpt-19-07 - documentation].
Genode OS Framework release 19.05 | 2019-05-29
##############################################
| The highlights of version 19.05 are a new kernel-agnostic virtualization
| interface, initial support for the 64-bit ARM architecture, the use of
| C++17 by default, a new tool chain based on GCC 8.3, updated C and SPARK
| runtimes, and the consolidation of build directories across boards.
We dedicated the release cycle of Genode 19.05 to platform topics at various
levels. The flagship feature is certainly the introduction of our
kernel-agnostic virtualization interface. It has been in the works for more
than a half year and gives us the prospect of running virtual machine monitors
like Seoul and VirtualBox seamlessly across Genode's supported kernels.
The second major theme is the extension of Genode's CPU-architecture support
to 64-bit ARM (AARCH64). This step motivated the update of many parts of the
framework's fundamental infrastructure, ranging from the tool chain (updated
to GCC 8.3), over the C runtime (updated to FreeBSD 12 libc), to the dynamic
linker. The new tool chain, in turn, paved the ground for enabling C++17 by
default.
With the diversity of kernels, CPU architectures, and boards growing, we are
constantly striving to remove friction and redundancies between Genode's
underlying platforms. The current release eventually consolidates the build
directories not only across kernels but also across all boards of a given
CPU architecture. This vastly increases the velocity of Genode-based system
scenarios when targeting multiple boards or emulators at the same time.
Further details about these and many more improvements are given in the
[https:/documentation/release-notes/19.05 - release documentation of version 19.05...]
Sculpt as a Community Experience | 2019-03-19
#############################################
| The fourth stage of Sculpt OS introduces a new federated software
| provisioning model while giving the user full control over the
| component deployment via a novel graphical user interface.
With Sculpt CE, we enter the final stage of the evolution of Sculpt OS as
envisioned roughly one year ago. Initially geared towards die-hard enthusiasts
only, each revision became more and more user friendly. The previous version
Sculpt VC already offered a glimpse of Sculpt's unique user interface in the
form of an interactive component graph.
The just released Sculpt OS "as a community experience" (CE) combines this
tangible notion of component compositions with a completely federated software
provisioning model that cuts out middlemen like an app store or a
distribution. With Sculpt CE, components can be offered by a federation of
independent software providers selectable by the user. The software
installation is sandboxed and protected via digital signatures. The
integration of components with the rest of the system is completely under
control by the user. With the principle of least privilege at the heart
of Sculpt's architecture, you - the user - can fearlessly install and run
software without the need to ultimately trust the software providers.
Sculpt CE is intended to work in tandem with the new community blog
[https://genodians.org - Genodians.org] where developers and users exchange
experiences and announce new software. The best way to watch how the
Sculpt story continues is the RSS feed of Genodians.org.

With [https://genodians.org - Genodians.org], the Genode community has gained
a new place for exchanging ideas, announcing current developments, giving
tutorials, and sharing experience stories. In contrast to the formal character

Genode OS Framework release 19.02 | 2019-02-28
##############################################
| Version 19.02 enhances Sculpt OS with a federated software provisioning
| model, showcases the use of Java for an IoT network appliance and the
| creation of a component-based web service, improves the runtime support
| for Ada and SPARK, and adds board support for i.MX6 Quad Sabrelite and
| Nitrogen6 SoloX.
Our first release of 2019 pays tribute to this year's
[https://genode.org/about/road-map - road map] topic
of making Genode relevant and attractive for a broader community.
First, it enhances Sculpt OS with an easy-to-use way to discover, install,
and integrate software originating from different providers into a running
Sculpt system. Conversely, software providers get a distribution channel
directly to the user, secured by cryptographic signatures. Unlike commodity
OSes that rely on app stores or distributions, there is no middleman between
software providers and users in Sculpt OS.
Second, it makes the world's most popular programming language - Java -
available. Our port of OpenJDK facilitates just-in-time compilation on both
32-bit ARM and 64-bit x86 architectures. The use of Java within a Genode
system is nicely showcased by an exemplary IoT network appliance.
Third, to foster a strong sense of community, the release introduces a
Genode-based federated blogging platform, which enables users and
developers alike to share ideas, practical tips and tricks, and announcements.
[https://genodians.org - Genodians.org] is open for everyone to participate.
Other highlights of Genode 19.02 are the improved runtimes for the
Ada/SPARK and OCaml programming languages, and the added support for the i.MX6
Quad Sabrelite and Nitrogen6 SoloX boards.

Road Map for 2019 | 2019-01-15
##############################
| In 2019, we will focus on practical use cases, on interoperability, and
| on harmonizing Genode with existing applications and programming languages.
The past Year of Sculpt was dedicated to bringing Genode to the desktop on
commodity PC hardware. Now is a good time to focus on making the Sculpt OS
relevant and appealing for a broader community. The road map for 2019 features
three major ambitions towards that goal. First, making Genode easier
approachable and usable by presenting practical use cases while fostering a
stronger sense of community among users and developers. Second, simplifying
the use of existing applications and programming languages in Genode-based
systems. And third, improving the interoperability of Genode with existing
protocols and systems.
The complete story behind the new road map is presented at the
[https:/about/road-map - road-map page].
Genode OS Framework release 18.11 | 2018-11-29
##############################################
| Genode 18.11 is focused on improving quality assurance on various fronts,
| including static code analysis, on-target test orchestration, and
| code-coverage measurements. Furthermore, it introduces support for Mirage-OS
| unikernels, a new health-monitoring mechanism, a Genode SDK, an SSH server,
| and a new window layouter.
On our road map for 2018, we identified software quality and resilience
as one of the major topics for this year. With the current release, we fulfil
this promise on various levels, ranging from static code analysis, over
the gathering of test-coverage metrics, a new Genode-based test-automation
framework, over to the health monitoring of components at runtime.
The second theme of the current release is the use of Genode for network
appliances and server applications. On that account, the new ability of
hosting Mirage-OS unikernels directly on top of Genode as well as a new SSH
server component clear the way to entirely new application areas.
Further highlights of the current release are the enhanced flexibility of the
GUI stack of Sculpt OS, the increased network performance on Xilinx Zynq, the
initial version of a Genode SDK, performance improvements of the base-hw
kernel on NXP i.MX platforms, and the updated language support for Ada and
Java.
These and many more topics of the new version are covered by the

Dual licensing of 3rd-party Genode components | 2018-11-16
##########################################################
| To nurture a sustainable ecosystem around the Genode OS framework, we
| introduce a new approach for conducting dual-licensing businesses enabled
| by Genode.
Since founded ten years ago, Genode Labs pursues the Genode project based on a
dual-licensing business model, which allows us to fund the development of
Genode as an independent team. The licensing business is enabled by the
combination of the AGPLv3 as a strong copyleft license with the library-like
nature of Genode. Until today, this model is applicable to our framework but
impractical for 3rd-party component developers. To foster a sustainable
ecosystem around Genode, we wish to enable others to pursue a similar business
model while maintaining the spirit of open collaboration and free software.
We eventually crafted a new license called "Genode Component Public License"
(Genode CPL) specifically for components developed by 3rd parties, outside of
Genode Labs. The article
[https://genode.org/documentation/articles/component_public_license - Dual licensing of 3rd-party Genode components]
provides the rationale, license text, and FAQ of this software license.

===============================================
Release notes for the Genode OS Framework 19.02
===============================================
Genode Labs
In our [https://genode.org/about/road-map - road map] for 2019, we stated
our goal to make Genode more relevant and appealing for a broader community.
The current release takes a big leap towards that goal: It opens up Sculpt
OS for 3rd-party software providers, introduces a federated blogging
platform about Genode-related topics, and makes the world's
[https://www.tiobe.com/tiobe-index/ - most popular] programming language
(Java) available to Genode users.
With the 4th stage of the evolution of Sculpt OS - themed as "community
experience" (CE) - Genode's custom general-purpose OS introduces a novel and
simple way for users to discover software, and for software providers to
announce software. There is no middle man like an app store or a distribution!
We hope that this federated model of software provisioning and deployment will
have a vitalizing effect on the community around Genode. On a practical level,
the interactivity of the new version is a playful and fun experience. Section
[Sculpt OS as a community experience (CE)] gives a rough overview about
*Sculpt CE*. A ready-to-use disk image will be released mid of March.
When speaking of "software providers", we don't think of anonymous
repositories. Software - and Free Software in particular - is developed and
provided by individuals after all. So in our federated way of software
distribution, we want to highlight this individuality. For this reason, we
launched a new blogging platform for Genode-related stories called
[https://genodians.org - Genodians.org], which gives everyone who is
enthusiastic about Genode - users and developers alike - a platform to express
ideas, announce software, or share practical tips and tricks. As explained in
the [https://genodians.org/nfeske/2019-01-07-welcome - initial posting],
*Genodians.org* is - in the spirit of Sculpt's software distribution model -
also organized in a federated way. The content is hosted and remains
completely under control by the respective authors. The website merely
aggregates and presents the content. It goes without saying that Genodians.org
is based on Genode. The system image that contains the entire web appliance -
from the kernel over the content management to the web server - is contained
in a 8 MiB disk image.
Section [Genodians.org as a showcase of a Genode-based web appliance] goes
into more detail.
We identified the support of popular programming languages as one key aspect
to attract a broader community. With the current release, our port of
*OpenJDK* (Section [Java]) for both 64-bit x86 and 32-bit ARM has reached a
mature state suitable for the creation of web services. This paves the way
towards quite exciting new system creations, like the *Boot2Java* system
presented in Section [Showcase of a Java-based network appliance].
On the account of programming-language support, we are happy to announce
a vastly improved runtime support for *Ada* and *SPARK* (Section
[Ada and SPARK] as well as the initial support for OCaml (Section [OCaml]).
Besides the work on shiny features, the current release cycle included a
profound *spring cleanup* described in Section
[Base framework and OS-level infrastructure].
It thereby finalizes the huge API modernization initiated almost three years
ago.
Sculpt OS as a community experience (CE)
########################################
When we laid out the road map for Sculpt OS a little more than one year ago,
we envisioned four stages of development. Sculpt EA was geared towards
die-hard early adopters facilitating the live editing of the system using a
text editor. Sculpt TC was targeted at "the curious" and included a graphical
user interface for common administrative tasks. Sculpt VC introduced the
visual composition of the system using an interactive graph. Even though
Sculpt already allowed for the installation of components from different
software providers at this stage, it offered no simple means to discover
software and the installation still required the manual editing of "launcher"
text files.
The final - community experience - stage of the plan ought to foster the
federated provisioning of software. Software providers should have the ability
to announce new packages. Conversely, users should be able to "subscribe" to
such announcements, similar how one would subscribe to an RSS feed. Once
software is discovered in this way, it should take only a few clicks to
install and integrate it into the running Sculpt system. No command-line
interface should stand in the way of discovery.
Sculpt CE is the realization of this idea.
For Sculpt users, the discovery starts at the '+' menu. In contrast to Sculpt
VC where the menu offered a rather long list of components to choose from, the
menu now offers nothing to be excited about.
[image sculpt_ce_menu]
However, at the very bottom, there is a new menu entry "Depot ...", which
leads to a sub menu with a list of enabled software providers. If connected to
the network, it also shows an entry named "Selection ...".
[image sculpt_ce_menu_depot]
The "Selection" sub menu allows the user to enable software providers.
[image sculpt_ce_selection]
When clicking on one of the checkboxes, the package index of the provider is
downloaded and the checkbox is highlighted. In the example, "nfeske" is
already enabled.
By clicking on the top-left triangle, one can always go one menu up. Back in
the depot menu, selecting a software provider will now display the index of
available packages. When selecting a new package, it can be installed via a
single click:
[image sculpt_ce_install]
Once the package is installed, the menu takes the user to a dialog for
integrating the package as a new component into the running Sculpt system. For
each resource required by the package, the user can decide how to connect it.
For example, the file system to be mounted at _/config/_ of a fresh
noux-system instance can be routed to any file system service the user wishes.
The noux-system won't know which file system is selected. It will just work
with it.
[image sculpt_ce_routes]
As soon as all routes are defined, the dialog presents a button for adding the
component to the system.
Using this interactive work flow, the discovery of software and its
integration becomes a rather playful process.
To make a once composed system permanent, one can use the inspect window to
copy the _/config/managed/deploy_ file to the _config/19.02/_ directory of your
Genode partition. This way, the deployment configuration will take effect
immediately at boot time.
Genode 19.02 comes with Sculpt CE included. As usual, we will take a bit
of time following the release for thorough testing and refining before
announcing an updated disk image mid March. We would greatly appreciate
your feedback during this phase! For baking a fresh Sculpt image, please
refer to the
[https://genode.org/documentation/articles/sculpt-vc - documentation]
of Sculpt VC, but using the Git tag '19.02' instead of 'sculpt_vc'.
Announcing software packages
----------------------------
The community experience of Sculpt CE will ultimately depend on the
participation of software providers. To become listed in the selection dialog
mentioned above, you may consider including your public key and download
location at the Genode repository at
[https://github.com/genodelabs/genode/tree/master/depot - /depot/].
For the announcement of packages, a software provider can publish so-called
"index" files for a particular Sculpt version in the software provider's
depot. E.g., the index of packages supported on Sculpt 19.02 would be located
at _index/19.02_ within the depot. Like any other depot content, index files
are digitally signed. An example index for the software provider "nfeske"
would look as follows:
! <index>
! <index name="GUI">
! <pkg path="nfeske/pkg/sticks_blue_backdrop/2019-02-22"
! info="default desktop background"/>
! <pkg path="nfeske/pkg/themed_wm/2019-02-26"
! info="ready-to-use window manager"/>
! </index>
! <pkg path="nfeske/pkg/nano3d/2019-02-22"
! info="simple software-rendering demo"/>
! </index>
Each '<pkg>' node refers to a package with a concrete version and a short
description. By nesting '<index>' nodes, software categories can be defined.
Index files can be published like any other depot content using the
_depot/publish_ tool, which takes care about compressing and digitally signing
the published information:
! ./tool/depot/publish nfeske/index/19.02
To ease the updating of the index with current package versions, the
_sculpt.run_ script creates the _depot/index/<version>_ file from the input
found in _repos/gems/run/sculpt/index_. The latter file is void of any version
numbers.
For any questions about the process, please consult the Genode
[https://genode.org/community/mailing-lists - mailing list].
Showcase of a Java-based network appliance
##########################################
With OpenJDK in good shape (Section [Java]), we have created a Genode scenario
that demonstrates JVM's ability to execute well on embedded hardware. As
target platform, we choose an ARM (i.MX 6) based SoC with two integrated
network interface controllers. In the scenario, the Genode system boots
directly into a Java application, which in turn spawns two HTTP server
instances where each instance communicates through a dedicated NIC. Both
server instances run as one Java program.
[image java_nic_filter]
The Java application (a JAR file) is loaded from the board's SD card, and
therefore, can easily be replaced. If you are interested in Java and ARM SoC,
the full details and a step by step instruction can be found at our
[https://genodians.org/ssumpf/2019-02-27-java-19-02 - Genodians.org] site.
Genodians.org as a showcase of a Genode-based web appliance
###########################################################
[https://genodians.org - Genodians.org] is our take on a federated blogging
platform about Genode-related topics. It does not host the actual content
but rather aggregates content hosted elsewhere.
[image genodians]
The site periodically fetches content in the form of zip archives containing
raw text and PNG images, extracts the archives, and transforms the text into
HTML using a custom static site generator. The result of the transformation
process is served by the lighttpd web server.
This system is based on Genode and can be found here:
:Genodians.org repository:
[https://github.com/genodelabs/genodians.org]
A few noteworthy technical points about the site:
* The periodic process of downloading, extracting, and transforming content
is realized via the 'fetchurl', 'extract', and 'sequence' components.
* The textual content uses the markup of the
[https://github.com/nfeske/gosh - GOSH]
text processing tool, which is similar to
[https://daringfireball.net/projects/markdown/ - Markdown].
* The custom static site generator consists of a plain makefile and a few GOSH
style files. The makefile is executed within a noux instance, which is
Genode's custom Unix runtime environment. It is re-spawned for each
iteration. As GOSH is written in Tcl, the tclsh is used within the noux
environment.
* The lighttpd web server uses a statically supplied SSL certificate.
* The most time-consuming part of creating Genodians.org was the CSS
definition.
* The entire system image is about *8 MiB* in size. It includes the following
ingredients:
* Kernel (e.g., NOVA),
* Basic Genode components such as init, NIC router, the VFS server,
* Network driver (based on iPXE),
* Linux TCP/IP stack as a library,
* Curl, libssh, libssl, libcrypto, lighttpd
(for downloading and serving content),
* libarchive, zlib, liblzma (for extracting the downloaded content)
* Noux, coreutils (stripped down), bash, GNU make, and tclsh (for
transforming text into HTML)
More information about the site's inner working will be posted in a series
of articles - guess where? - at Genodians.org!
Base framework and OS-level infrastructure
##########################################
Removal of deprecated APIs
==========================
Almost three years ago -
with [https://genode.org/documentation/release-notes/16.05 - version 16.05] -
we started the transition to Genode's modern API. One year later - in
[https://genode.org/documentation/release-notes/17.05#Completed_component_transition_to_the_modern_API - version 17.05],
we announced the completion of this transition but we retained the deprecated
APIs to accommodate Genode users that picked up the new API only gradually.
With the current release, we finally drop the deprecated APIs along with a
couple of other legacies:
* The _base/timed_semaphore.h_ has been removed. In hindsight, officially
providing this utility was a big mistake because it lured developers into
a wrong direction. In fact, we found that there is no legitimate use of it
when a component is designed in a clean way. If a component relies on a
timed semaphore, it should better be redesigned. There are two noteworthy
places where a timed semaphore is still used as a band-aid solution:
the 'pthread_cond_wait' implementation of the libc, and DDE for rump
kernels. Those places now host a private copy of the timed semaphore, but
should ultimately be reworked.
* The header _base/printf.h_ has been removed along with the log back end
for 'printf'. The 'Console' with the format-string parser is still there
along with 'snprintf.h' because the latter is still used at a few places,
most prominently the 'Connection' classes.
* The notion of a 'Ram_session' exists no more since the former RAM-session
interface was merged into the PD-session interface in
[https://genode.org/documentation/release-notes/16.05#Consolidation_of_core_s_SIGNAL__CAP__RM__and_PD_services - version 16.05].
Still, the types were preserved (by typedefs to 'Pd_session') to keep up
API compatibility. Those last traces of 'Ram_session' are gone now. The
'Env::ram()' accessor returns the 'Ram_allocator' interface, which is a
subset of the 'Pd_session' interface.
* The use of the global 'Genode::env()' accessor function is not possible
anymore.
* The old 'Child_policy::resolve_session_request' interface that returned
a 'Service' instead of a 'Route' has been removed.
* Boolean accessor methods are no longer prefixed with 'is_'. E.g., instead
of 'is_valid()', use 'valid()'.
* All connection constructors need the 'Env' as argument.
* The 'Reporter' constructor needs an 'Env' argument now because the
reporter creates a report connection.
* The old notion of 'Signal_dispatcher' is gone. For receiving
asynchronous notifications, the 'Signal_handler' interface must be used.
* Transitional headers like _os/server.h_, _cap_session/_,
_volatile_object.h_, _os/attached*_dataspace.h_, and
_signal_rpc_dispatcher.h_ have been removed.
* The distinction between 'Thread_state' and 'Thread_state_base' does
not exist anymore. Only 'Thread_state' prevails.
* The header _cpu_thread/capability.h_ along with the type definition of
'Cpu_thread_capability' has been removed. Use the type
'Thread_capability' defined in cpu_session/cpu_session.h instead.
* The _os/ram_session_guard.h_ has been removed.
Use 'Constrained_ram_allocator' provided by _base/ram_allocator.h_ instead.
Source-tree reorganization
==========================
Timer moved from os to base repository
--------------------------------------
Traditionally, the user-level timer was hosted at the os repository at
_drivers/timer/_. However, since the timer and timeout handling have become
part of the base library (the dynamic linker), the component naturally belongs
to the base repository. It is now located at _base/src/timer/_ and
_base-<kernel>/src/timer/_ respectively.
Note that this change affects include paths for the former
_include/os/timer/_, _include/os/alarm.h_, and _include/os/duration.h_
headers. Those can now be found in _include/base/_.
Consistent naming of block components
-------------------------------------
Regarding the naming of files and APIs, Genode follows the convention of
avoiding abbreviations. Most components follow this convention, with the block
servers being the exception to the rule. Those were named "part_blk" or
"rom_blk". With the current release, we removed this inconsistency by renaming
those offenders, changing "blk" to "block". Closely related, abbreviations
like "cli" and "srv" have been replaced by "client" and "server".
Improved API safety
===================
XML-parsing API
---------------
Genode consistently uses XML for component configurations and for reports
generated by components. The latter are often consumed by other components.
This puts the XML parser into a prominent position. Genode's XML parser
comes in the form of the 'Xml_node' class. Since it was introduced before the
age of modern C++, it offers several risky "C-ish" methods, in particular
accessors that return pointers, raising memory-safety concerns. To promote a
safe programming style, the following parts of the interface are subject to
change now:
* The 'Xml_node::addr', 'Xml_node::content_addr', and 'Xml_node::content_base'
accessors will be removed because it is all too easy to store the returned
pointers and forget about the lifetime of the originating 'Xml_node' object.
Fortunately, in practice, those methods are rarely used because information
is typically represented in attributes, not as node content. However, to
still support the access to the raw content, the new
'Xml_node::with_raw_node', 'Xml_node::with_raw_content', and
'Xml_attribute::with_raw_value' methods call a functor taking the raw byte
buffer and size as arguments. This way, the lifetime of the pointer is
naturally bound to the scope of the functor.
* The new 'with_sub_node' method calls a functor with the specified
sub node as argument and thereby reduces the need for the traditional
'Xml_node::sub_node' method, which returns an 'Xml_node'.
The latter is risky because an 'Xml_node' contains a pointer to the actual
data. In contrast, the lifetime of the 'Xml_node' processed via the new
'Xml_node::with_sub_node' is naturally bound to the scope of the passed
functor.
* The 'Xml_attribute::value' and 'Xml_node::value' methods now take an
argument of type 'T &out' instead of 'T *out', which eliminates the
uncertainty of a possible nullptr argument.
The original interface will still be available for a while but it will
eventually be removed.
Simplified session-policy handling
----------------------------------
Most server components make use of the 'Session_policy' utility for selecting
a client policy depending on the session label. However, the pattern of its
use remained a bit inconsistent across components, in particular the handling
of the case where no policy could be found. Some components outright
denied the session where others implemented a fallback to a built-in default
policy. This inconsistency is now removed.
Following the principle of deny-by-default the absence of a matching policy
denies the session request. Since the 'Session_policy::No_policy_defined'
exception is a typedef to the 'Genode::Service_denied' exception, a server
does not need to explicitly handle it, which simplifies the implementation.
With this change, the 'No_policy_defined' case is always an error case. Hence,
the new version of 'Session_policy' prints a error message, which relieves the
server developer from implementing diagnostics in the server code.
As a consequence of this change, scenarios that used to rely on the
policy-fallback approach of some servers - notably the NIC bridge, window
manager, the window decorators - need a slight adaption: To enable the
fallback to a default policy, a '<default-policy>' node must be explicitly
specified in the server's configuration.
Removed pointers from Genode::Fifo interface
--------------------------------------------
To make the use of the 'Genode::Fifo' data structure more safe, all methods
that return pointers have been replaced by methods that call a functor with
a reference as argument.
New server-side block-request stream API
----------------------------------------
The current block-component API (_os/include/block/_) was designed at a time
long before Genode's modern component API was introduced. Back then, the use
of blocking calls was prevalent. Today, we design components to work
asynchronously. The original block-server API was successively enhanced to
allow the implementation of asynchronous block servers but it remained "upside
down" while growing more complicated than it should be.
To simplify the implementation and verification of block servers, the current
release introduces a modern API that will eventually replace the original
block-component API. The new API is called *block-request stream* and can be
found at
[https://github.com/genodelabs/genode/blob/master/repos/os/include/block/request_stream.h - os/include/block/request_stream.h].
It is designed with the following considerations:
* It anticipates the asynchronous operation of block servers by default.
Using the new API, such servers - in particular block-device drivers - can
be implemented as state machines triggered by client requests and device
interrupts.
* It reinforces the memory safety of the server code by not returning any
pointers or references.
* It relieves the server developers from handling special cases (like a
congested acknowledgement queue) while being flexible enough to accommodate
different categories of components like drivers, resource multiplexers
(part_block), and bump-in-the-wire components in a natural way.
* It naturally supports the batching of requests as well as zero-copy
(device DMA directly into the client's communication buffer).
The use of the new API is illustrated by the artificial test at
[https://github.com/genodelabs/genode/blob/master/repos/os/src/test/block_request_stream/main.cc - os/src/test/block_request_stream/].
We plan to successively migrate all existing block servers to this new API
and will remove the traditional block-component API eventually.
GUI stack
=========
Motivated by our work on Sculpt as described in Section
[Sculpt OS as a community experience (CE)], Genode's GUI stack received
the following improvements:
Window management
~~~~~~~~~~~~~~~~~
To improve the visual appearance of Sculpt's administrative GUI, the *themed*
*decorator* was enhanced with an option to disable decorations based on the
window label. By setting the 'decoration' attribute of a '<policy>' node to
"no", matching windows appear without any border, which is desirable for
Sculpt's component graph.
Furthermore, the themed decorator accepts the '<policy>' attribute
'motion=<number>'. The default value is 0. If a value higher than 0 is
specified, window-geometry changes are applied as an animation where the
<number> denotes the number of animation steps. This feature is used for
smoothing the placement of Sculpt's component graph.
The *motif* *decorator* - which is a nice alternative to the themed decorator -
is now giving visual feedback to mouse clicks. For example, while the user
drags a window by clicking on the window title, the title bar appears as
pressed, which creates an improved sense of responsiveness.
Unified shape-report routing
----------------------------
Applications propagate custom mouse-cursor shapes by issuing "shape" reports
towards the pointer component. The pointer component correlates the session
labels of the incoming shape reports with the label of nitpicker's currently
hovered client. Hence, an application's shape report session should take the
same route as its nitpicker session.
The presence of the window manager as an intermediary of the nitpicker session
breaks this rule. Consequently, rather awkward label-rewriting magic was
required when routing shape reports originating from windowed applications. To
make the shape reporting more natural, the window manager has become able to
proxy shape reports on behalf of its clients. When routing a shape through the
window manager, the labels of both the nitpicker sessions as well as the shape
report sessions contain the intermediary "wm ->" part.
Unicode support for the graphical terminal
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The terminal has been changed to represent characters as 16-bit codepoints
internally. It thereby became able to display a much larger variety of
international characters when using a suitable font. Unicodes are sent through
the terminal session via bursts of UTF-8 bytes now.
As a collateral change, the generic 'Codepoint' class became printable via
Genode's 'Output' interface. This way, a codepoint can easily be serialized
into UTF-8 bytes.
Programming languages
#####################
Ada and SPARK
=============
_The work described within this section was contributed by_
_[https://componolit.com - Componolit]. Thanks to Alexander Senier_
_and Johannes Kliemann for the fantastic collaboration!_
The integration of SPARK/Ada programs was improved greatly and the Ada runtime
was renamed to 'spark'. This emphasizes its main purpose: trusted components
that can be formally verified. A more feature-rich runtime based on 'libc' was
added to genode-world under the name 'ada'.
Build system integration
------------------------
Up until now, the (deprecated) 'gnatmake' tool was used to build Ada object
files. This was unfavorable for two reasons: First, multiple invocations of
gnatmake would sporadically corrupt the compiler-generated Ada linker files
('.ali') and break parallel builds. Second, Ada dependency information did not
get propagated into Genode's build system such that certain source changes
failed to trigger a rebuild.
For these reasons the 'gnatmake' tool has been dropped in favor of regular
compiler calls as done for all other languages. To facilitate consistent
rebuilds on source-code changes, the
[https://github.com/Componolit/ali2dep - ali2dep] tool was created. From an
'.ali' file, it produces '.d' files suitable for direct inclusion into
Genode's build system.
Until the integration into the toolchain, 'ali2dep' support needs to be
enabled through the 'CUSTOM_ALI2DEP' variable (absolute path or command name
if the command is in 'PATH'). By default, a warning about the absence of the
tool is emitted and dependency information is not generated. You can add this
variable to the 'etc/tools.conf' of your build directory as follows:
! CUSTOM_ALI2DEP = /path/to/ali2dep
Elaboration code
----------------
Previously, Ada programs that required elaboration code to be run were
unsupported on Genode. With this release, Ada programs are bound using
'gnatbind', which results in elaboration code being generated. An additional
benefit comes in the form of proper error messages at compile time if, for
example, source code is missing or outdated.
To run an Ada main program with elaboration, calls to 'adainit()' and
'adafinal()', generated by the binder, need to be added to your
component-construction code:
! extern "C" void _ada_main(void);
! extern "C" void adainit();
! extern "C" void adafinal();
!
! void Component::construct(Genode::Env &env)
! {
! adainit();
! _ada_main();
! adafinal();
! env.parent().exit(0);
! }
Note, that the name of the Ada main program ('_ada_main()') in this example
depends on the name of your main procedure.
Debug output
------------
Support for 'GNAT.IO' was added to the runtime. 'GNAT.IO' is a stripped-down
text I/O facility, which we map to a terminal session on Genode. Only output
is supported at the moment. A pointer to a terminal session has to be provided
to the ADA runtime in order to use 'GNAT.IO'. Please refer to
_repos/libports/src/test/gnatio/_ as an example.
Unit testing
------------
To facilitate test-driven development of Ada components, the
[https://www.adacore.com/documentation/aunit-cookbook - AUnit] unit testing
framework was ported to Genode. It is located in the genode-world repository
whereas a usage example can be found at 'src/test/aunit'. Note that the full
Ada runtime ('ada') is required as the framework uses features not present in
the SPARK runtime.
Java
====
Since Genode release
[https://genode.org/documentation/release-notes/18.11#Java_language_runtime - 18.11],
we continued our effort to enable the just-in-time (JIT) compiler for OpenJDK.
We are happy to announce that we were able to achieve this goal. The JIT
compiler is now enabled as default for both x86 (64 bit) and ARM (32 bit),
which significantly improves the performance of the Java virtual machine for
these architectures.
Additionally, we even further improved JVM's performance by taking advantage
of more aggressive compiler optimizations. This triggered some unidentified
bugs and led to a greatly enhanced stability of OpenJDK.
For a small hello world example we offer a simple run script:
! make run/java
For a more complex scenario please refer to Section
[Showcase of a Java-based network appliance].
Nim
===
Support for Nim has been removed from the Genode build system to encourage
building Nim components out-of-tree using the Nimble package manager.
The compatibility of the base system with the Nim runtime will be monitored
and improved regardless of this change.
OCaml
=====
A proof-of-concept port of the OCaml bytecode interpreter has been placed
in the world repository. This allows simple programs that are compiled to the
bytecode instructions to be executed and is a first step in supporting the
OCaml language. This interpreter does not yet include the standard library.
Therefore only language primitives are available. Porting the standard library
appears to simply be a matter of defining a build process. The greatest
hurdle to porting existing OCaml applications would seem to be finding a path
into the workflow of the OPAM package tooling.
Libraries and applications
##########################
New utility for taking screenshots
==================================
The flif_caputure screenshot utility has been added to the world repository.
This utility implements a framebuffer and input service which it proxies to
its parent. When the utility observes the *PrtSc* key, it captures the content
of the framebuffer and writes it to the file system in the FLIF image format,
FLIF being chosen primarily for its uncomplicated API. To use the utility in
practice, the common case would be to run it as a client of the default window
manager with a second window manager stack running as a client of the capture
utility. This allows capture behavior and scope to remain simple and explicit.
The background story behind the tool is covered by a dedicated
[https://genodians.org/ehmry/2019-01-31-flif_capture - posting] at Genodians.org.
Growing use of the Genode-World repository
==========================================
The [https://github.com/genodelabs/genode-world - Genode-World] repository
contains software that is not strictly part of the official Genode OS
framework but rather supplemental. In particular, it contains ports of
3rd-party software to Genode. The pool of ported software is steadily growing,
which moves the world repository more and more into the spotlight of Genode
users. For example, among a variety of games and experimental components, our
port of OpenJDK ([Java]) is also hosted there. To acknowledge the growing
importance of the world repository, we added the building of all world depot
archives to our nightly build tests.
With this baseline of quality assurance in place, it was a good time to move
supplemental software such as Dosbox, FUSE, libav, libSDL, and its companion
libraries from the Genode repository to the Genode-World repository. Speaking
of libSDL, as part of the curation of the world content, the library back end
of libSDL has been changed to the direct use of the nitpicker session
interface instead of the lower-level framebuffer and input interfaces. Thanks
to this change, many scenarios could be greatly simplified, in particular
packages designated for the use in Sculpt OS.
Updated or removed 3rd-party software
=====================================
The following 3rd-party software received an update:
* OpenSSL updated to version 1.0.2q with 'SSL_CONF_*' enabled,
as needed by lighttpd's mod_openssl.
* Lighttpd updated to version 1.4.52, with TLS enabled.
* libpng updated to version 1.6.36
* jbig2dec updated to version 0.15
Removal of VirtualBox 4
-----------------------
All regular users of Genode's VirtualBox port migrated to version 5 a long
time ago. Version 4 was still maintained because this is the only version
supported on the Muen separation kernel. However, since the focus of the Muen
developers recently moved towards the use of nested virtualization, our
version of VirtualBox 4 is no longer vital for Muen. So we could remove it.
Platforms
#########
Board support for i.MX6 Quad Sabrelite and Nitrogen6 SoloX
==========================================================
In 2018, we extended our device-driver support for NXP i.MX 5 and 6 based ARM
platforms. This year, we continue our commitment to this platform with
additional support for the NXP reference board i.MX6 Quad Sabrelite and the
Nitrogen6 SoloX, which features dual Gigabit Ethernet.
Resizeable virtual framebuffer on Linux
=======================================
When executing Genode on Linux, we use a libSDL-based pseudo driver for
running graphical scenarios. This *fb_sdl* server has now been enhanced with
the ability to resize the SDL window. Such a resize event is translated into
Genode's framebuffer resize protocol. Thereby, the resizing of the host window
looks like a mode change to Genode's GUI stack. This greatly eases the testing
of the mode-change handling of components like the nitpicker GUI server.
Tooling and build system
########################
Enforced 'override' annotations
-------------------------------
The '-Wsuggest-override' warning complains about implementations of virtual
functions that lack the override keyword. If the implementation of a virtual
method is marked as 'override' the compiler checks for a matching virtual
method in the base class. If there is no such method, the implementation
unexpectedly diverged from the interface.
An interface may change over time, which is especially troublesome when it
contains a default implementation of a virtual method. Without 'override'
annotations, the compiler will silently add the outdated implementation of the
derived class as an overload of the interface's default implementation, which
introduces a subtle but potentially serious bug.
To rule out such bugs in the future, we made 'override' annotations mandatory
when using the default strict warning level.
Generalized use of the depot by run scripts
-------------------------------------------
With more and more run scripts using archives out of Genode's depot, we gained
experience with typical usage patterns. In particular, we found the universal
use of the configurable depot user preferable over the hard-wiring of
'genodelabs'. Hence the 'depot_user' function has become a built-in function
of the run tool.
Repeat mode for the depot-autopilot test environment
----------------------------------------------------
The _depot_autopilot.run_ script now supports the environment variable
'TEST_REPEAT' with the possible values 'until_forever' and 'until_failed'.
When specified, the tests are run in a loop. The latter argument is
particularly useful for reproducing sporadic errors.
New run script to execute a single test w/o the depot
-----------------------------------------------------
The new _os/run/test.run_ script allows for the quick execution of an
individual test from the build directory while side-stepping the depot.
It expects a 'PKG' variable specifying the test package. E.g.,
! make run/test KERNEL=nova PKG=test-xml_node
Note that it does not cover all test packages right now.
The tool and its limitations are explained in more detail by a dedicated
[https://genodians.org/nfeske/2019-02-05-shortcut-for-testing - posting]
at Genodians.org.
Support for undefined-behavior sanitizer
----------------------------------------
The
[https://developers.redhat.com/blog/2014/10/16/gcc-undefined-behavior-sanitizer-ubsan/ - UndefinedBehaviorSanitizer]
(UBSan), also described in the
[https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html - GCC documentation],
can detect undefined behavior while a program is running.
With the current release, this diagnostic feature of GCC becomes available for
analyzing Genode components. By specifying 'SANITIZE_UNDEFINED = yes' in a
'target.mk' file, the '-fsanitize=undefined' compiler flag is enabled and the
program is linked with libubsan and libsanitizer_common. The program has to
call 'env.exec_static_constructors()' and 'sanitizer_init(env)' upon startup
to initialize the sanitizer libraries. Whenever undefined behavior is detected
while the program is running, a "runtime error:" message including the source
code location of the error is printed to the log.

Release notes for the Genode OS Framework 19.05
===============================================
Genode Labs
The Genode release 19.05 is primarily focused on platform support.
It adds compatibility with the 64-bit ARM architecture (AARCH64),
comes with improvements of the various kernels targeted by the framework,
and extends the list of supported hardware. The increased diversity of base
platforms calls for unifications to keep the hardware and kernel landscape
manageable.
On that account, Genode uses one reference tool chain across all kernels
and CPU architectures. The current release upgrades this tool chain to
*GCC 8.3* with C++17 enabled by default
(Section [Tool chain based on GCC 8.3.0 and binutils 2.32]).
To increase the velocity of Genode system scenarios across different boards
of a given CPU architecture, the release introduces the notion
of *board and kernel-agnostic build directories* presented in Section
[Unified build directories for ARM]. Once built for one particular
CPU architecture, the same binaries can be deployed at any supported board or
kernel without recompilation. This vastly accelerates the workflow when
targeting multiple boards and emulators at once.
As another major unification effort, the current release introduces a new
*kernel-agnostic virtualization* interface. Up until now, virtualization
used to be inherently tied to a specific kernel. Thanks to the new interface,
however, one virtual machine monitor implementation can be combined with
kernels as different as NOVA, seL4, or Fiasco.OC. No recompilation needed.
As outlined in Section [Kernel-agnostic virtual-machine monitors], Genode
has now become able to run the Seoul VMM on all those kernels, while
VirtualBox is planned to follow.
On our [https://genode.org/about/road-map - road map], we originally
planned several user-facing features related to Sculpt OS. However, in the
light of the major platform efforts, we decided to defer those topics instead
of rushing them.
That said, the release is not without new features. For example, our port
of *OpenJDK* has become able to host the Spring framework and the Tomcat web
server, there are welcome improvements of the *package-management tooling*,
and we added new options for user-level networking.
Finally, version 19.05 is accompanied with the annual revision of the *Genode*
*Foundations book* (Section [New revision of the Genode Foundations book]),
which is now available as an online version in addition to the regular PDF
document.
Kernel-agnostic virtual-machine monitors
########################################
Since the introduction of Genode's
[https://genode.org/documentation/release-notes/17.02#Genode_Application_Binary_Interface - Application Binary Interface]
in the 17.02 release,
Genode components can be assembled once for a given hardware platform and
executed without further adjustments on all the supported kernels. However, at
that time, the supported virtual machine monitors - a port of VirtualBox 4 & 5,
Seoul, and our
[https://genode.org/documentation/articles/arm_virtualization - custom VMM] -
remained kernel specific.
Of course, last remaining bastions tempt to be taken! So last year, we started
the venture to unify our virtualization interface across different kernels.
Starting point was the already existing Genode VM interface of our custom VMM
on ARM. We took it and extended the interface with caution to the x86 world.
Having an eye on the requirements of our already supported VMMs on NOVA(x86),
namely VirtualBox and Seoul, the VM interface got extended with missing
features like multiple vCPU support and specific VM handlers per vCPU.
In parallel, we started to investigate the other x86 microkernels with regard
to hardware-assisted virtualization features, namely seL4 and Fiasco.OC.
Over several weeks, we iteratively extended the interface. On the one hand
we familiarized ourself with the kernel interfaces of seL4 & Fiasco.OC while
on the other hand considered known requirements of the NOVA microhypervisor.
Additionally, we kept our custom VMM for ARM still compatible with the new VM
interface.
During this time, it became apparent that the control flow on a VM resume/pause
and a VM event(exit) are different between seL4/Fiasco.OC and NOVA/base-hw.
For seL4 and Fiasco.OC, a VM is resumed by making a blocking syscall on the
kernel. On a VM event, the blocking syscall would return. Logically, on both
kernels the VMM 'calls' into the VM.
On base-hw and NOVA, it is the other way around. Whenever a VM causes a VM
event, the kernels set up either an asynchronous notification (base-hw) or a
synchronous IPC call (NOVA) to the VMM. In both cases the VMM executes a prior
registered VM event handler as response.
Upon return of the VM event handler, the kernel resumes the VM. Logically, on
NOVA and base-hw the VM 'calls' into the VMM. The following two figures
contrast the different flows of control between a user-level virtual machine
monitor and the respective kernels.
[image vm_seq_foc_sel4]
Control flow of handling virtualization events on Fiasco.OC and seL4
[image vm_seq_nova_hw]
Control flow of handling virtualization events on NOVA and the base-hw kernel
Hiding this differences behind a common VM interface was the challenge we were
faced, accepted, and won. Finally, at one point in December we had all 3
x86 kernels running with a test VMM - without re-compilation. The toy VMM
(vmm_x86.run) runs multiple vCPUs on multiple physical CPUs and tests several
VM events/exits.
After this major breakthrough, we spent the days left before Christmas to
adjust the Seoul VMM to the new VM interface, freeing it from the ties to the
NOVA kernel. The choice to start with Seoul stems from the fact that it is -
compared to VirtualBox - much smaller and therefore easier to debug if things
go wrong in the beginning. After one week, the Seoul VMM became in principle
kernel independent and worked again on NOVA. After some more days, it started
to hobble on seL4 and Fiasco.OC as well.
With the New Year, VirtualBox was the next target where all NOVA kernel
specific calls were replaced with the new Genode VM interface. Mid of January,
the work showed first results by having a prototype running simple VMs on NOVA
again. At this point, it became apparent that this venture is not anymore an
adventure. All the findings and technical details so far got condensed to a
[https://fosdem.org/2019/schedule/event/microkernel_virtualization - presentation]
given and recorded at the [https://fosdem.org/2019 - FOSDEM 2019] in Brussels
in February in the
[https://fosdem.org/2019/schedule/track/microkernels_and_component_based_os - Microkernel and Component based OS]
developer room.
At this point, we started transforming our prototype for the 4 kernels into a
clean solution to be featured in Genode 19.05. Eventually, the kernel-agnostic
Seoul VMM runnable on seL4, Fiasco.OC, and NOVA entered Genode master. In the
Genodians article
[https://genodians.org/alex-ab/2019-05-09-seoul-vmm - Seoul VMM and the new VM interface],
we conserved the current state and a few performance measurements.
Shortly before this release, the kernel-agnostic VirtualBox VMM version on
Genode/NOVA got ready. The kernel-agnostic version is in principle capable to
run Linux VMs and Windows 7/10 VMs on Genode/NOVA. Currently, this version
must still be considered as experimental and does not run on seL4 or
Fiasco.OC.
Because of the experimental nature of the kernel-agnostic VirtualBox VMM
version, we decided to keep the kernel-specific version for NOVA for the
moment. This gives us time to test and improve the kernel-agnostic version. It
also allows us to compare both versions to each other.
If time and interest permits, we will consider bringing the virtualization
support on Genode/seL4 and Genode/Fiasco.OC on par with Genode/NOVA.
When building VirtualBox with Genode 19.05,
you will find both the 'virtualbox5-nova' and the new 'virtualbox5' binaries
in the build directory. The former relies on NOVA's kernel interface whereas
the latter uses Genode's kernel-agnostic VM interface. Nightly tested run
scenarios with the new VM interface are named 'vbox5_vm*.run' and can be found
in the 'repos/ports/run' directory.
Broadened CPU architecture support and updated tool chain
#########################################################
With the major update of Genode's tool chain and library infrastructure in
tandem, the framework gains a consistent architecture support across x86-32,
x86-64, ARM-32, RISC-V, and the newly added AARCH64. This includes the tool
chain (Section [Tool chain based on GCC 8.3.0 and binutils 2.32]), the base
framework, the dynamic linker, and the C runtime
(Section [Updated dynamic linker and C runtime]).
Together with this update, we took the chance to wrap up our long-time move
away from board-specific build directories to one generic build directory
shared by multiple kernels and boards for a given CPU architecture
(Section [Unified build directories for ARM]).
Tool chain based on GCC 8.3.0 and binutils 2.32
===============================================
Genode uses a tailored tool chain based on GCC and binutils that is used
across all supported kernels and architectures. Since the previous tool-chain
update in version
[https://genode.org/documentation/release-notes/17.05#Tool_chain - 17.05],
we relied on GCC 6.3. After two years, it was time for an update, motivated by
three major reasons. First, the C++17 standard is common-place now. We Genode
developers anticipate the improvements that come with it. Second, RISC-V and
AARCH64 are now supported by mainline GCC. Up till now, we had to maintain a
custom patch set for Genode's RISC-V support. AARCH64 was not supported yet.
Third, our increasing engagement with SPARK depends on recent improvements of
the Ada compiler that is part of GCC.
With Genode 19.05, the tool chain is now based on binutils version 2.32, GCC
version 8.3.0, GDB version 8.2.1, gcov version 8.3.0, standard C++ library
version 8.3.0.
The tool chain supports x86 (32 and 64 bit), ARM, AARCH64, and RISC-V.
For C++ code, the C++17 standard is enabled by default.
The update of the tool chain provided a perfect opportunity to replace the
former use of gnatmake with a much more natural integration of Ada in Genode's
build system, using a custom ali2dep dependency-extraction tool developed
by [https://github.com/Componolit/ali2dep - Componolit].
In contrast to the previous versions, we switched to a versioned installation
directory for the new tool chain. By default, it is now installed to
_/usr/local/genode/tool/19.05/_. This eases the use of different tool-chain
versions for different development branches.
:Tool-chain installation:
[https://genode.org/download/tool-chain]
Caveats
-------
The tool-chain update required a number of adaptations throughout the source
tree, and may affect Genode users too:
* The silent fall-though within switch statements must now be replaced
by an explicit annotation of the form
! [[fallthrough]]
* The 'register' keyword is no longer valid with C++17. Hence, it must
be removed from the code.
* Types marked as 'Noncopyable' can no longer have an implicit default
constructor. A default constructor must be provided manually.
Updated dynamic linker and C runtime
====================================
The tool-chain update is accompanied with a major update of the dynamic linker
and the C runtime to cover both the AARCH64 and RISC-V architectures in
addition to the traditional x86 and ARM architectures.
FreeBSD 12 supports AARCH64 and RISC-V. Hence, by updating our C runtime to
this version, Genode's libc support extends to those architectures now.
Until now, Genode's dynamic linker supported only the eager binding of symbols
at loading time on the *RISC-V* architecture. With the current version, we
lifted this limitation in favor of lazy binding as used on all other CPU
architectures.
Unified build directories for ARM
=================================
In version
[https://genode.org/documentation/release-notes/17.02#Genode_Application_Binary_Interface - 17.02],
we introduced unified build directories for x86, which allow us to build and
run Genode scenarios on various kernels while using only one build directory.
This concept leverages Genode's cross-kernel binary compatibility to make
the switch from one kernel to another - like developing on base-linux and
deploying on base-nova - a seamless experience.
On ARM, this concept was held back by a third dimension. The
system-integration step does not only depend on the CPU architecture and
the kernel but also on the used board. Our traditional approach was the
use of one build directory per board. Granted, within such a build directory,
one could easily switch between different kernels like Fiasco.OC and seL4.
But on ARM, we find an extreme proliferation of different board
configurations, which share the same CPU architecture but demand different
integration steps. This ensues large redundancies among different build
directories. Switching from one board to another - even when most binaries
happen to be exactly the same - requires an additional rebuilding effort.
With version 19.05, we took the chance to generalize the unified build
directory concept to support multiple different boards per build directory,
greatly reducing the friction when switching kernels and boards for a given
CPU architecture (like ARMv7a). This change has the following implications:
* Drivers no longer depend on the SPEC values as configured for a build
directory.
* All *binaries* are now *named unambiguously*. For example, the USB drivers
for the Panda (OMAP) and Arndale (Exynos) boards were formerly called
'usb_drv' but were different programs. They just never happened to
appear in the same build directory. In the new version, they are named
'panda_usb_drv' and 'arndale_usb_drv' respectively and can thereby
peacefully co-exist within the same 'armv7a' build directory.
Note that this binary renaming will likely affect existing run scripts.
* Include paths no longer hide the board details, which makes the included
code much more easy to follow.
* Run scripts need to pick the right binary, depending on the used board.
Since the board is no longer tied to a build directory, the selection
of the used board has become a build-time variable 'BOARD' following
the successful pattern of how we specify the targeted 'KERNEL'.
To avoid the pollution of run scripts with difficult conditions, we wrap
the drivers needed for a particular board and use case into so-called
_drivers_ packages. Such a package can be instantiated within a generic
scenario using a nested init instance. The details about the drivers and
how they access the hardware remain nicely hidden inside this building block.
Currently, there exist _drivers_ packages for two distinct use cases:
:drivers_interactive pkgs: contain all drivers needed for simple
interactive scenarios, including graphical output and user input.
:drivers_nic pkgs: contain the drivers needed for communication over the
network.
Whenever a run script fits one of these use cases, it can rely on the
corresponding ready-to-use drivers packages via:
! import_from_depot [depot_user]/src/[base_src] \
! [depot_user]/pkg/[drivers_nic_pkg] \
! ...
With the drivers package incorporated, the drivers subsystem can be
instantiated as follows (note the absence of any board or kernel-specific
details):
! <start name="drivers" caps="1000">
! <resource name="RAM" quantum="32M" constrain_phys="yes"/>
! <binary name="init"/>
! <route>
! <service name="ROM" label="config">
! <parent label="drivers.config"/> </service>
! <service name="Timer"> <child name="timer"/> </service>
! <any-service> <parent/> </any-service>
! </route>
! <provides> <service name="Nic"/> </provides>
! </start>
Using the 'BOARD' build variable
--------------------------------
The new 'BOARD' variable selects the board to use. It can be specified either
as a 'make' command-line argument (or environment variable), or defined in the
build-directory configuration (_etc/build.conf_). The following boards are
available:
:arm_v6: rpi
:arm_v7a: arndale, imx53_qsb, imx53_qsb_tz, imx6q_sabrelite, imx7d_sabre,
nit6_solox, odroid_x2, odroid_xu, panda, pbxa9, usb_armory,
wand_quad, zynq_qemu
:arm_v8a: rpi3
:x86_64: pc, linux, muen
:x86_32: pc, linux
:riscv: spike
Please note, when running Genode on Linux or the Muen separation kernel -
although it is run on common x86 PC hardware - we treat both runtime
environments as separate "boards" because their device driver environments
are fundamentally different.

Base framework and OS-level infrastructure
##########################################
Modernized block-storage interfaces
===================================
With the current release, we revisited Genode's interfaces for accessing
block devices to ease the implementation of asynchronous I/O, to accommodate
zero-copy block drivers, and to support trim and sync operations.
Revised RPC interface
---------------------
The 'Block::Session' RPC interface remained untouched for a long time.
We have now rectified long-standing deficiencies.
First, *sync requests* used to be handled as synchronous RPCs. This is bad
for components like part_block that multiplex one block device for multiple
clients. One long-taking sync request of one client could stall the I/O for
all other clients. The new version handles sync requests as asynchronous
block-request packets instead.
Second, the new version allows a server to dictate the *alignment* of
block-request payload. This way, a driver becomes able to use the payload
buffer shared between client and server directly for DMA transfers while
respecting the device's buffer-alignment constraints.
Third, we added support for *trim* as an asynchronous block operation.
However, as of now, this operation is ignored by all servers.
Fourth, each block operation can now be accompanied with a client-defined
request tag independent from the other parameters of the operation. The tag
allows a block-session client to uniquely correlate acknowledgments with
outstanding requests. Until now, this was possible for read and write
operations by taking the value of the request's packet-stream offset. However,
sync and trim requests do not carry any packet-stream payload and thereby lack
meaningful and unique offset values. By introducing the notion of a tag, we
can support multiple outstanding requests of any type and don't need to
overload the meaning of the offset value.
New client-side API
-------------------
We have now equipped the 'Block::Connection' with a framework API for the
implementation of robust block-session clients that perform block I/O in an
asynchronous fashion.
An application-defined 'JOB' type, inherited from 'Connection::Job',
encapsulates the application's context information associated with a block
operation.
The life cycle of the jobs is implemented by the 'Connection' and driven by
the application's invocation of 'Connection::update_jobs'. The 'update_jobs'
mechanism takes three hook functions as arguments, which implement the
applications-defined policy for producing and consuming data, and for the
completion of jobs.
We plan to gradually move the existing block clients to the new API to benefit
from the latency-hiding effects of asynchronous I/O. The first updated client
is the _block_tester_ component located at _os/src/app/block_tester/_, which
received a number of new features like the choice of the batch size. Please
refer to the accompanied README for a detailed description of the
block-tester.
Unified types for time values
=============================
[https://genode.org/documentation/release-notes/17.05#New_API_for_user-level_timing - Two years ago],
we introduced the so-called timeout framework to provide a general solution
for requirements unmet by the bare timer-session interface - most notably
timer-session multiplexing amongst multiple timeouts, and microseconds
accuracy. Up to this day, the timeout framework has proved itself many times
in both real-life appliances and artificial tests and has become the standard
front end for timing in Genode applications.
With this release, we solved one of the few remaining limitations with the
framework by enabling timeouts of up to 2^64 microseconds (> 500000 years)
across all supported architectures. In order to achieve this, we replaced the
former machine-word-wide types used for plain time values by unsigned 64-bit
integers. We did this not only inside the timeout framework but also to almost
all code in the basic Genode repositories that uses the framework.
By doing so, we also paved the way for a second step, in which we are planning
to replace plain time values as far as possible with the abstract 'Duration'
type. With this type in place, the user wouldn't have to worry anymore about
any plain-integer implications when calculating with time values.
Support for chained EBR partitions
==================================
Having an active community around Sculpt leads to bugfixes in unexpected
places. By now we prefer to use a GPT rather than an MBR based partition table
and although we test 'part_block', the component that parses the tables, on
regular basis, the handling of chained EBR's was flawed. Community member
[https://genodians.org/valerius/index - Valery Sedletski] who relies on such a
setup encountered this flaw and provided a bug report, which enabled us to
quickly reproduce and fix the problem.
IP forwarding with port redirection
===================================
The NIC router can now be used to redirect to individual destination ports on
port-forwarding. To express the redirection, the new 'to_port' attribute can
be added to '<tcp-forward>' and '<udp-forward>' rules in the NIC router
configuration. If the new attribute isn't added, the rules behave as usual and
forward with an unaltered destination port.
Libraries, languages, and applications
######################################
Ada/SPARK runtime and SPARK-based cryptography
==============================================
The SPARK runtime has been updated to GCC 8.3. SPARK components do not require
'Genode::Env' or a terminal session anymore. Debug messages can still be
printed using 'GNAT.IO', which uses 'Genode::log' and 'Genode::error'
internally now.
Threading support, which was never fully implemented, has been removed to
further simplify the runtime. This simplification allowed us to prove absence
of runtime errors for the secondary stack allocator and other parts of the
runtime.
[https://github.com/Componolit/libsparkcrypto.git - Libsparkcrypto] is a
library of common cryptographic algorithms implemented in SPARK. It is
free-standing and has a very small footprint. The port of libsparkcrypto for
Genode has been added to the libports repository. Thanks to Alexander Senier
and Johannes Kliemann of [https://componolit.com - Componolit] for maintaining
the Ada/SPARK runtime and libsparkcrypto.
To accommodate the use case of block encryption, we added the small wrapper
library 'aes_cbc_4k' around libsparkcrypto that provides a simple C++
interface for the en/decryption of 4 KiB data blocks. It uses AES-CBC while
incorporating the block number and the private key as salt values.
Improved resilience of the sequence tool
========================================
We have a simple component that starts other components sequentially. It
will exit whenever one of those components has exited with an error.
However, this component is used by our [https://genodians.org - Genodians]
appliance where it controls the content-update mechanism. Since updating
involves fetching content via HTTP/S depending on external events, e.g.,
the remote site is not reachable, the sequence tool might exit. In a long
running appliance, this is obviously not a useful action where no one is
in place to restart the sequence tool. Rather than increasing the overall
complexity of the appliance by introducing such a management component, we
added a _keep-going_ feature to the sequence tool that will instruct it
to carry on even if one of the started components has failed.
Please look at _repos/os/src/app/sequence/README_ for instructions on
how to use the feature.
NIC-bus server for private LANs
===============================
The 'nic_bus' server was added to the world repository as an alternative
to the 'nic_router' and 'nic_bridge' components. The name may be a slight
misnomer, but this component acts neither as a hub, switch, or router.
The 'nic_bus' implements unicast and multicast Ethernet packet switching
between sessions, but drops any unicast packet not destined for a session
attached to the bus. This is in opposition to the behavior of a typical
Ethernet switch and is intending to create simple, software-defined
local-area-networks for native components as well as virtual machines.
In practice the component has been used for attaching VMs to the
[https://yggdrasil-network.github.io/ - Yggdrasil] overlay network via
a bus-local IPv6 prefix.
Distributed Genode
==================
In
[https://genode.org/documentation/release-notes/16.08#Network-transparent_ROM_sessions_to_a_remote_Genode_system - 16.08],
we initially released the _remote_rom_ components that act as communication
proxies. A communication proxy transparently relays a particular service to
another Genode system. As the name suggests, the remote_rom relays ROM
sessions.
Originally implemented as a proof of concept using bare IP packets, broadcast
MACs and static configuration of IP addresses, we added several improvements
to allow a more general use. First, we adopted the size-guard idea for packet
construction and processing from the NIC router. Furthermore, we adopted the
single-threaded implementation style that was already established in other NIC
components. Thanks to Edgard Schmidt for this contribution. Second, we
implemented ARP requests to eliminate broadcasting. Third, we moved from bare
IP packets to UDP/IP and implemented a go-back-N ARQ strategy in order to
reliably transmit larger ROM dataspaces.
As the remote_rom proved valuable for distributing functionality across
multiple Genode devices, we also applied this concept to the LOG session in
order to transmit LOG output from a headless Genode device to a
[https://genode.org/download/sculpt - Sculpt] system for instance. The udp_log
component provides a LOG service and sends the LOG messages as UDP packets to
another machine. The log_udp reverses this process by receiving these UDP
packets and forwarding the messages to a LOG service. An example can be found
in the world repository at _run/udp_log.run_ and _run/log_udp.run_.
Seoul and VirtualBox virtual machine monitors
=============================================
Besides the conversion of the Genode back end of Seoul to the new VM
interface, we added mouse-wheel support to the PS/2 model and changed the VMM
to request a single GUI/nitpicker session rather than distinct framebufer and
input sessions.
Similar to the Seoul VMM, the VirtualBox VMM was adjusted to the new VM
interface and now uses the GUI/nitpicker session. The original kernel-specific
VirtualBox version tied to the NOVA kernel is still available. Both versions
can be used simultaneously.
Use of Nim decoupled from Genode build system
=============================================
With this release, all integration with Nim tooling has been removed from the
Genode build system as a result of maturing support for additional languages
via Genode SDKs. Building Nim components independently of the Genode source
tree has the benefit of smaller upstream checkouts and faster build times, and
has yielded components such as the
[https://genodians.org/ehmry/2019-03-22-depot_9P - 9P server] used in some
Sculpt developer workflows. An example of an independent build system for Nim
components is
[https://genodians.org/ehmry/2019-04-27-nim_packaging - documented on the Genodians blog].
OpenJDK improvements
====================
Within the 19.05 release cycle, we further improved Genode's OpenJDK support
by enabling additional networking infrastructure required by the
[https://spring.io - Spring Framework]. The improvements especially concern
support for SSL connections, which enabled us to successfully execute an embedded
[https://docs.spring.io/spring-boot/docs/current/reference/html/howto-embedded-web-servers.html - Tomcat]
server natively on Genode x86 and ARMv7 platforms using the same JAR archive.
This line of work continues our Java for embedded systems effort as described in
our [https://genodians.org/ssumpf/2019-02-27-java-19-02 - Boot2Java] article.
Having these features in place, our Java efforts will continue in the direction
of Java Swing and the support of input devices in the future, with the ultimate
goal of seamless Java application integration into
[https://genode.org/download/sculpt - Sculpt OS].
Device drivers
##############
Improved Zynq board support
===========================
The initial support of the Xilinx Zynq-7000 SoC was added to our custom kernel
in 15.11. Since then, the support of this hardware has been incrementally
extended. The definitions of memory maps, frequencies, and RAM sizes for
different Zynq-based boards are found in the world repository.
One of the major additions in this release is the initialization of the L2
cache. In this context, we also added a simple cache benchmark at
_repos/os/run/cache.run_ that measures the access times for memory regions of
different size and thereby reveals the number of cache levels and their sizes.
With the latest improvements of the network driver in 18.11, a zero-copy
approach was introduced as an effort to eliminate bottlenecks in the driver's
performance. However, this modification also introduced a kernel dependency of
the driver in order to flush packet-buffer memory from the cache before handing
it over to the DMA-controller. With this release, we moved back to using
uncached dataspaces in order to eliminate the cache flushes and the kernel
dependency. Interestingly, we could not recognize a significant impact on the
driver's performance, which confirms the presumption that flushing the cache
nullifies the gain from using cached dataspaces.
In order to enable the continuous operation of the network driver, we extended
the driver-internal error handling that is necessary to recover the network
driver in certain situations.
_Thanks to Johannes Schlatow for contributing and maintaining Genode's Zynq support!_
Updated Intel network drivers
=============================
As a result of recurring issues with modern Intel i219 laptop NICs, we
updated the driver sources for Intel chipsets to the latest upstream
iPXE version. This update also enables all NIC variants, which were
missing from our manually maintained PCI ID whitelist before.
New drivers-nic and drivers-interactive depot packages
======================================================
As already described in section [Unified build directories for ARM],
_drivers_nic_ packages nicely hide the driver configuration internals needed for
a specific board to communicate over the network. Until now there was only one
package available for x86 based PCs. Now, additional _drivers_nic_ packages
are available for:
:boards: imx53_qsb imx6q_sabrelite linux muen pbxa9 rpi zynq
Beside the formerly available _drivers_interactive_ packages for linux, pbxa9
and pc, there are now additional ones for the following:
:boards: imx53_qsb rpi muen
Platforms
#########
For most kernel environments, the core component provides a ROM module named
'platform_info', which comprises information provided by either the kernel or
the bootloader. The information entails e.g., the TSC clock frequency and
framebuffer dimensions. Most of the information is of interest for special
device driver components only.
Over the time, there was an increasing need to incorporate the information
about which kernel Genode runs on top of. Thereby, special test components,
like depot_autopilot could use the information to, e.g., skip certain tests
on kernels known to not support them. Moreover, there are rare corner-cases
where kernels behave differently, for instance, interrupts are enumerated
differently on certain ARM platforms. Rather than maintaining multiple driver
binaries with different names depending on specific kernels, the
'platform_info' ROM module can now be used to differentiate between kernels
when necessary.
Execution on bare hardware (base-hw)
====================================
This release comes with fundamental optimizations and corrections for
executing Genode on bare hardware when using the core component as the actual
kernel.
In the past, we could observe some serious peculiarities regarding the timing
behavior on the hw kernel. After a careful review, we identified the obstacles
that led to time drifts on several platforms and to quite different runtime
execution.
First and foremost, we limited the CPU-load wasted by the kernel, which
unnecessarily made new scheduling decisions quite often. When the hw kernel
was started as an experiment, there was less focus on performance, but more on
simplicity. Instead of caring about state changes that make a scheduling
decision necessary, the scheduler was asked for the next execution context
unconditionally, whenever the kernel was entered. Now, the scheduler gets
invoked only whenever an execution context gets blocked, or unblocked, or if
the kernel's timer fires due to a timeout. This dramatically influences the
CPU-load caused by the hw kernel in a positive way.
The timing accuracy got increased by reworking most hardware timer drivers
used in the kernel to let the timer never stop counting. Moreover, we limit
the scope in between reading the clock and adjusting the next timeout to a
minimum. The whole internal time representation got widened to 64-bit.
In some rare use cases, we could observe components that do I/O polling, and
thereby actively ask for pending signals, to starve. The reason was a gap in
the hw kernel's syscall API. Beside the ability to wait for signals, the
base-library offers the ability to check for pending signals without blocking
in the case of no available signals. The equivalent call in the kernel was
still missing, and is now present and integrated in the base-library of
base-hw.
ARM architecture
----------------
With this release, we add the i.MX 7 Dual SABRE reference board to the rich
hardware zoo Genode runs directly on top of. This includes the use of the
virtualization extensions available on this platform.
Apart from the new board support, several optimizations were added
specifically for the ARM architecture. Several unnecessary cache maintenance
operations were eliminated, which resided in the code base since the time when
the kernel used a separate address-space only. Moreover, the kernel-lock -
used when several execution contexts on different CPU-cores try to enter the
kernel - does not spin anymore. Instead, the CPU goes into a sleep-state to
save energy. As a side-effect, multi-core scenarios become usable when
executed in Qemu.
X86 architecture
----------------
Since the newly used compiler version makes aggressive use of FPU instructions
including the core component, the kernel itself makes use of FPU registers and
state. Therefore, lazy FPU switching becomes a no go for base-hw. Although, we
incorporated eager FPU switching into the ARM-specific part of the hw kernel
already, the x86 version was still missing it. Now, the FPU context of a thread
gets saved and restored on every kernel entry and exit on x86 too.
Updated Muen separation kernel
==============================
The Muen port has been updated to the latest development version, which comes
with many improvements under the hood. Most notably this version of Muen brings
support for Linux SMP subjects, GNAT Community 2018 toolchain support as well
as much improved build speed, which is most noticeable during autopilot runs.
Additionally, the debug server buffer size in the Genode system policy has been
increased to avoid potential message loss in case of rapid successive logging.
_Thanks to Adrian-Ken Rueegsegger of [https://codelabs.ch - Codelabs] for_
_this welcome contribution!_
NOVA microhypervisor
====================
The kernel got updated due to the tool-chain update to GNU G++ 8.3.0.
Additionally, several issues reported by Julian Stecklina regarding FPU and
page-table synchronization got addressed. The kernel memory allocation at boot
time got more flexible to address target machines with fragmented physical
memory. Additionally, the vTLB implementation is no longer used on AMD
machines whenever nested paging is available.
seL4 microkernel
================
With this release, we extend the variety of hardware to run Genode on top of
the seL4 kernel with NXP's i.MX 7 Dual SABRE reference board. To do so, we had
to update the seL4 tools used to craft a bootable ELF image to a state that is
consistent with the currently supported seL4 kernel version 9.0.1.
As a side-effect of this development work, the General Purpose Timer (GPT) used
in the i.MX series can now be used as a timer service component.
Fiasco.OC microkernel
=====================
As with base-hw and seL4, we add the i.MX 7 Dual SABRE reference board to the
list of working hardware for Genode running on top of the Fiasco.OC
microkernel. Moreover, with Fiasco.OC it is now possible to take the first
steps using Genode on the ARM 64-bit architecture. Therefore, we add Raspberry
Pi 3 as a candidate board to be used with Genode/Fiasco.OC. Currently, only
basic tests without peripheral dependencies are supported.
Tooling and build system
########################
Improved handling of missing ports
==================================
The depot tools _tool/depot/create_ and _tool/depot/extract_ now detect and
report all missing third-party sources - called ports - for a given set of
archives at once. Additionally, the user can tell the tools to download and
prepare such missing ports automatically by setting the argument
'PREPARE_PORTS=1'. Please be aware that doing so may cause downloads and
file operations in your _contrib/_ directory without further interaction.
These features make building archives with dependencies to many ports more
enjoyable. If you merely need a list of ports that are missing for your
archives, you can use the new tool _tool/depot/missing_ports_.
For more details you may read the
[https://genodians.org/m-stein/2019-05-21-depot-missing-ports - article on genodians.org].
Automated depot management
==========================
When using the 'import_from_depot' mechanism of the run tool, one frequently
encounters a situation where the depot lacks a particular archive. Whenever
the run tool detects such a situation, it prompts the user to manually curate
the depot content via the _tool/depot/create_ tool. The need for such manual
steps negatively interferes with the development workflow. The right manual
steps are sometimes not straight-forward to find, in particular after
switching between Git branches.
To relieve the developer from this uncreative manual labor, we extended the
run tool with the option '--depot-auto-update' for managing the depot
automatically according to the needs of the executed run script. To enable
this option, use the following line in the build configuration:
! RUN_OPT += --depot-auto-update
If enabled, the run tool automatically invokes the right depot-management
commands to populate the depot with the required archives, and to ensure the
consistency of the depot content with the current version of the source tree.
The feature comes at the price of a delay when executing the run script
because the consistency check involves the extraction of all used source
archives from the source tree. In regular run scripts, this delay is barely
noticeable. Only when working with a run script of a large system, it may be
better to leave the depot auto update disabled.
Please note that the use of the automated depot update may result in version
updates of the corresponding depot recipes in the source tree (recipe hash
files). It is a good practice to review and commit those hash files once the
local changes in the source tree have reached a good shape.

Release notes for the Genode OS Framework 19.08
===============================================
Genode Labs
The stated theme of this year's [https://genode.org/about/road-map - road map]
is "bridging worlds", which expresses our ambition to smoothen the practical
use of Genode-based systems such as Sculpt OS. The current release pays
tribute to this ambition by addressing a great number of practical concerns:
How to accommodate the staggering variety of keyboard layouts out there?
(Section [Flexible keyboard layouts])
How can the system gracefully respond when confronted with exotic USB devices?
(Section [Storage-stack improvements])
How to set the system time from within the system? How does SNTP fit in here?
(Section [General system time concept])
How to approach the remote administration of the system?
(Section [Enhanced SSH terminal])
How to copy and paste text securely between mutually distrusting subsystems?
(Section [Clipboard])
Or how to overcome the captive portal of a Hotel WiFi with Sculpt OS?
(Section [Disposable VM for handling captive portals])
By providing answers to those questions, we believe to make Genode - and Sculpt
OS in particular - generally more useful.
As another take on "bridging worlds", we continue our effort to bring the rich
Sculpt OS software stack to the 64-bit ARM world, in particular to our most
loved SoC family, namely NXP i.MX. Section [64-bit ARM and NXP i.MX8] reports
on our progress in this direction.
Under the hood, there are a few exciting developments that will greatly reduce
the effort of running existing software on Genode. In particular, Genode's
(entirely optional) C runtime has gained the ability to emulate the
traditional execve and fork mechanisms.
(Section [Consolidation of the C runtime and Noux]) This will eventually
alleviate the need for our present noux runtime environment to the benefits of
better performance and increased flexibility.
Further highlights of Genode 19.08 are a major update of Qt5 to version 5.13
(Section [Updated Qt5]) and the continuation of our kernel-agnostic
virtualization story (Section [Virtualization]).
Flexible keyboard layouts
#########################
Genode is used worldwide in a multilingual context beyond Germany and common
technical realms of English. Therefore, we had to address localized
keyboard-input handling for quite some time now and introduced the
_input-filter_ component in
[https://genode.org/documentation/release-notes/17.02#Input-event_filter - 17.02].
The component merges input streams and applies several forms of input
transformations, in particular the application of keyboard layouts to
supplement the input-event stream with character events.
But as we are by no means localization experts, our solution, while performing
a solid job for selected layouts, also had some quirks and rough edges when it
came to French or even Swiss German. First, our oversimplified notion of
[https://en.wikipedia.org/wiki/Caps_Lock - Caps Lock] as _just a pressed Shift_
_key_ is plain wrong but part of all our character-generator configurations.
We just missed this drawback because none of our developers uses Caps Lock
regularly. Further, US English and Germany layouts work very well without
[https://en.wikipedia.org/wiki/Dead_key - dead keys], but crossing any German
border (except the Austrian) is impossible without support for key sequences
composing special characters. The French keyboard layout in Genode tried to
alleviate the lack of compose sequences by adding an additional Circumflex
modifier and character mapping, which unfortunately is not standard.
[image keyboard_stack]
Beginning at this state of affairs, we researched common practice in
international keyboard-input handling, sought a quasi-standard source for
layout configurations, and addressed the drawbacks mentioned before. During
our research we found out that no current implementation is void of critique
and, therefore, decided to look more into X11/XKB as our open-source
quasi-standard solution, but always had an eye on the proprietary world.
The handling of key events in X11/XKB happens on three layers.
:Key codes: On the key-code layer, the device driver programs the
keyboard and generates a stream of key-code (i.e., scan-code)
events, which represent the physical location of the actual key on
the keyboard.
:Key symbols: These key codes are mapped to key symbols, which
represent the label imprinted on the key. So, the key code producing
US English _Q_ (QWERTY keyboard) generates _A_ on a French keyboard
(AZERTY). Modifiers like Shift, AltGr, and Caps Lock are included in
the key-symbol mapping. Additionally, some layouts map key codes to
dead key symbols, which start the before-mentioned compose
sequences. Key repeat is also implemented as key-symbol repeat
actually.
:Characters: On top of this stack, the key symbols are mapped to
characters represented as Unicode codepoints or UTF-8 strings.
The procedure obviously includes key symbols that have no character
representation (e.g. Control and Alt). Key symbols forming a valid compose
sequence generate characters on this level (e.g., dead-key circumflex plus
e generates ê).
We limited our research to Western keyboard-input handling and only had a
blink into the direction of Chinese-Japanese-Korean (CJK) and advanced input
methods (IM). This simplification is supported by the fact that CJK can also
be based on the mechanisms mentioned with some limitations only. Nevertheless,
we do not expect to never touch this topic again.
After doing our homework of keyboard-input handling, we worked on squeezing
all available layout information out of X11/XKB, which resulted in a small
tool residing in _tool/xkb2ifcfg_. For those wondering, the name is just a
silly acronym for _XKB to input-filter_ _configuration_ that pays tribute to
the boringness of this task. After building the tool by a run of 'make' in the
tool path, it can be used as follows. Please make sure you have libxkbcommon
development packages installed beforehand.
! xkb2ifcfg generate <layout> <variant> <locale>
!
! xkb2ifcfg generate us euro en_US.UTF-8
! xkb2ifcfg generate de nodeadkeys de_DE.UTF-8
If the parameter combination is available, xkb2ifcfg prints a input-filer
chargen configuration for the selected layout to standard output. Valid
'layout' and 'variant' options can be figured out from the LAYOUTS section in
'man 7 xkeyboard-config', where 'variant' strings are depicted in parentheses
after the layout (e.g., 'us(euro)'). The 'locale' option has the standard
locale syntax (see /usr/share/i18n/locales). The tool needs all three
parameters to gather the correct key-map and compose-sequence information. The
generated chargen configurations include '<map>' and '<key>' nodes
corresponding to significant modifier states and '<sequence>' nodes (described
later). For simplicity of the generator, the '<key>' nodes always use the
'code="..."' attribute, but also have a comment with the UTF-8 character
appended.
! <key name="KEY_MINUS" code="0x00df"/> <!-- ß -->
Last, we addressed the improvement of the input-filter character generator and
the actual chargen configuration files in Genode. Therefore, we specified the
modifier configuration assumed by the standard chargen files as '<mod1>'
corresponds to Shift, '<mod2>' to Control, '<mod3>' to AltGr, and '<mod4>' to
Caps Lock.
! <mod1> <key name="KEY_LEFTSHIFT"/> <key name="KEY_RIGHTSHIFT"/> </mod1>
! <mod2> <key name="KEY_LEFTCTRL"/> <key name="KEY_RIGHTCTRL"/> </mod2>
! <mod3> <key name="KEY_RIGHTALT"/> </mod3> <!-- AltGr -->
! <mod4> <rom name="capslock"/> </mod4>
As outlined above, the '<key>' nodes generated by xkb2ifcfg always use the
'code' attribute for the Unicode codepoint. Because of this and because UTF-8
also refers to codepoints, we deprecated the 'b0/b1/b2/b3' attributes for
character definition with this release.
The chargen is also extended by the '<sequence>' configuration node. A
sequence node permits the definition of dead-key/composing character
sequences. With such sequences, the character is not generated instantly on
key press but only after the sequence is completed. If an unfinished sequence
can't be completed due to an unmatched character, the sequence is aborted and
no character is generated. We support sequences of up to four characters at
the moment.
For example, the French AZERTY
[https://docs.microsoft.com/en-us/globalization/keyboards/kbdfr.html - keyboard layout]
has a dead key for Circumflex Accent _^_ right of the _P_ key (which is
bracket left _[_ on US keyboards). When Circumflex is pressed no visible
character should be generated instantly but the accent must be combined with a
follow-up character (e.g., Circumflex plus _a_ generates _â_).
Dead keys can be defined in the '<key>' nodes of any '<map>' by using
codepoints not used for direct output, for example, Combining Diacritical
Marks beginning at U+0300. The French Circumflex example can be configured
like follows.
! <mod1>
! <key name="KEY_LEFTSHIFT"/> <key name="KEY_RIGHTSHIFT"/>
! </mod1>
! <map>
! <key name="KEY_Q" code="0x0061"/> <!-- a -->
! <key name="KEY_LEFTBRACE" code="0x0302"/> <!-- dead_circumflex -->
! </map>
! <map mod1="true">
! <key name="KEY_Q" code="0x0041"/> <!-- A -->
! </map>
! <sequence first="0x0302" second="0x0061" code="0x00e2"/> <!-- â -->
! <sequence first="0x0302" second="0x0041" code="0x00c2"/> <!-- Â -->
Fortunately, the configuration is automatically generated by xkb2ifcfg, but
admittedly quite extensive. Therefore, we manually amended the chargen
configurations before adding them to Genode, which also gave us the chance to
apply some adjustments like follows for AltGr in Swiss German.
! <map mod1="false" mod2="false" mod3="true" mod4="false">
! <key name="KEY_1" code="0x00a6"/> <!-- ¦ (*) -->
! <key name="KEY_4" code="0x00b0"/> <!-- ° (*) -->
! <key name="KEY_5" code="0x00a7"/> <!-- § (*) -->
! </map>
Beside the advanced input methods mentioned before, there are still loose ends
we are going to address in the upcoming releases. For example, the current key
handling in our Qt5 back end maps localized key symbols incorrectly (think
AZERTY vs. QWERTY) in combination with shortcuts like Ctrl-A.
64-bit ARM and NXP i.MX8
########################
64-bit ARM support in our custom base-hw kernel
-----------------------------------------------
By introducing rudimentary Raspberry Pi 3 support on top of the Fiasco.OC
kernel in the previous release, the first ARM 64-bit support has entered the
Genode OS framework. We continued pursuing the ARM 64-bit path and introduce
support for Raspberry Pi 3 as well as the i.MX8 evaluation kit (EVK), this
time using our own base-hw kernel.
Noteworthy additions in the base-hw kernel are support for the AARCH64 system
level architecture, and the use of the modern GIC v3 interrupt controller on
top of the i.MX8 EVK board. In comparison to the GICv2, GICv3 adds support for
more than eight CPUs, more than 1020 interrupt IDs, and offers fast register
access to the CPU interface, instead of memory-mapped I/O access. Minor
changes had to be made to the page-table implementation of ARMv7 with Large
Physical Address Extension (LPAE) to re-use it for ARMv8. Moreover, the
internal kernel API for TLB maintenance needed to be changed slightly for all
ARM platforms.
We expanded our regular testing infrastructure with two AARCH64 platforms,
namely Raspberry Pi 3 via Qemu and the NXP i.MX8 EVK board as physical
hardware. Both platforms are driven with a single CPU core only at the moment.
Network driver for i.MX7 and i.MX8
----------------------------------
We updated the 'fec' network driver to version 4.16.3, which adds support for
i.MX7 and i.MX8 SoCs. This makes i.MX8 a viable platform for Genode-based
networking scenarios.
Enhanced packaging and test infrastructure for ARMv8
----------------------------------------------------
Besides the improved base-hw kernel, we enabled additional infrastructure for
ARMv8 platforms. For example, noux packages - like _coreutils_, _bash_ - are
now available, the standard C++ library is in place, and support for Genode's
port of the Linux TCP/IP stack is enabled.
Additionally, ARMv8 is now regularly tested within our nightly
_depot_autopilot_ runs.
Base framework and OS-level infrastructure
##########################################
Tracing
=======
Support for fast tracing has been built into Genode for a long time. However,
the stakes to take advantage of this feature remained high because convenience
functions were not in place. With the current release, we added the support
for easy trace setups through a VFS plugin. The plugin is called _vfs_trace_
and can be mounted into a Genode component as follows:
!<config>
! <vfs>
! <trace ram=32MB/>
! </vfs>
!</config>
This configuration will create a trace file system at the root of the VFS. The
_ram_ attribute is mandatory and determines the maximum size of all trace
buffers. The file system forms a recursive directory structure that represents
the parent/child relationship of running components, whereas the leaf
directories represent single threads within a component. Each leaf directory
currently contains three files:
:'enable': Start or stop the tracing of a thread by writing "true" or "false"
into the file.
:'buffer_size': Allows for the configuration of the trace-buffer size for the
thread in the usual Genode format (e.g. 5M, 512K, 1024).
:'trace_buffer': This read-only file contains the current content of the trace
buffer. Each trace entry can only be read once, after that only new entries
appear. "tail -f" can also be used to display continuous output.
As an example, tracing is started by writing _true_ to the _enable_ file:
! echo "true" > enable
The trace buffer can then be displayed using Unix tools like _tail_
! tail -f trace_buffer
which provides a continuous output.
Additionally, we have added the _trace_ function to _base/log.h_ that
facilitates identical functionality as _Genode::log_
! Genode::trace("Tracepoint value: ", value);
In order to enable tracing, the parent must provide the "TRACE" service. For a
real world example on Sculpt OS, please refer to this
[https://genodians.org/ssumpf/2019-06-18-trace_fs - Genodians article].
With the _vfs_trace_ plugin in place, we removed the outdated _trace_fs_.
Consolidation of the C runtime and Noux
=======================================
On our [https://genode.org/about/road-map#August_-_Release_19.08 - road map],
we vaguely hinted at our plan for the "consolidation" of the noux runtime,
which is actually meant as a polite way of announcing that we are going to
remove it. We introduced the
[https://genode.org/documentation/release-notes/11.02#Noux_-_an_execution_environment_for_the_GNU_userland - Noux runtime]
in 2011 as a way to execute command-line-based GNU software directly on
Genode. It has served us well over the years and is - in fact - a crucial
ingredient of Sculpt OS and other system scenarios such as the Genodians.org
web server. Noux supplements Genode with two valuable assets, namely a
flexible and expandable virtual file system (VFS) layer, and the
implementation of the
[https://genode.org/documentation/release-notes/12.02#Noux_support_for_fork_semantics - Unix way]
to spawn applications ('fork' and 'execve').
In the
[https://genode.org/documentation/release-notes/17.02#Enhanced_VFS_infrastructure - meantime],
noux' VFS implementation has become independent from the noux runtime and is
now prominently employed by Genode's C runtime and the VFS server component.
Genode's C runtime became more and more complete, alleviating the use of noux
as POSIX compatibility layer except for programs that depended on a working
implementation of 'fork' and 'execve'.
The current release fills this remaining gap in Genode's C runtime by
providing 'fork', 'execve', and cousins such as 'wait4' and 'getpid' as
regular parts of the libc. This will eventually make noux redundant.
Note that this change does *NOT* make Genode reliant on POSIX. The C runtime
including the Unix features are entirely optional.
As one stepping stone of this undertaking, noux applications, which previously
had to be compiled for noux, have become binary compatible with the regular C
runtime. So one can execute programs like 'bash' directly as a Genode
component without any friction.
There are a few collateral improvements of Genode's dynamic linker and the C
runtime on the account of the new 'fork' and 'execve' implementation. E.g., in
addition to the already supported 'stdin', 'stdout', and 'stderr'
configuration, the libc can be instructed to initialize arbitrary file
descriptors as follows:
! <config>
! ...
! <libc ...>
! <fd id="3" path="/dev/log" writeable="yes" readable="no" seek="10"/>
! ...
! </libc>
! </config>
The libc-based implementation of 'fork' and 'execve' can be tried out via
the new _ports/run/bash.run_ script. Note that there are still a number of
limitations such as the lack of signal and ioctl handling. Pipes are not
supported, and shebangs ('#!') are not interpreted yet. That said, once those
missing pieces come into place, we can fade out the use of noux within Genode.
General system time concept
===========================
Briefly speaking, up to now there has been no notion of an overall concept of
system time in Genode. Components that need to have access to some kind of
real time are either configured locally, e.g., libc-based components access a
configured "device" (/dev/rtc), which just might be an inline file system
containing an artificial timestamp or the VFS RTC plugin, while other
components query some RTC session directly. Most of the time, this session is
provided by the 'rtc_drv' on x86 machines, which is somewhat costly as reading
the RTC via I/O ports takes time and is therefore done scarcely. For example,
the libc will query an RTC source only once and uses this initial value to
interpolate the current time. However, for executing long-running components,
it will be necessary to adjust the clock to compensate for any occurring clock
drift or to correct a misconfigured clock in general. In addition it is
desirable to be able to use a remote time source, e.g., an NTP-server, to
synchronize the system time.
To address this, we came up with the following concept:
[image system_rtc]
The new "System RTC" component, located at
_repos/libports/src/server/system_rtc_, acts as proxy for the RTC service in
front of the actual RTC driver. It uses the driver to get the initial RTC
value and then uses a timer session (via the timeout framework) to locally
interpolate the time. In contrast to querying the RTC driver, querying the
System RTC is fast.
The RTC driver and the System RTC are bundled up together in the new
_drivers-rtc-pc_ package. The runtime of this package requests two ROM modules
used to update the RTC value. The first one, named 'system_set_rtc', is used
to update the proxy component while the second one, called 'hw_set_rtc', is
used by the RTC driver to write the value into the battery-backed RTC. A
separate component, potentially accessing a remote time source, may generate
these ROMs to adjust the time in the package's runtime.
The new native *SNTP* client at _repos/libports/src/app/sntp_client_ is such a
component. It periodically requests the current time from a given SNTP server
and generates a report. The report produced by the component contains the time
as UTC/GMT. Depending on the system policy, it can be used to update the time
of the System RTC and/or instruct the driver to set the RTC value.
To propagate such changes to RTC values, the RTC session was enhanced by the
new 'set' signal. A client of the session can install a signal handler to
adapt its own time when necessary. Based on this, the time back end of the
libc was changed to instantiate a watch handler for the RTC device, which,
when triggered, will cause the libc to re-read the RTC value.
This constellation should, under normal operation, allow for second to
sub-second granularity updates of the overall system time and avoid drifting
away from network time.
Accessing SMBIOS tables
=======================
The System Management BIOS (SMBIOS) is a specification that allows for reading
management information produced by the BIOS of a system as a collection of
data structures in memory. It has the potential to eliminate the need for the
operating system to probe hardware for discovering present devices and their
characteristics. Nowadays, the SMBIOS specification is implemented widely in
PC systems, which includes modern UEFI systems as well. The data structures
are referred to as _tables_ or _records_ by public documentation.
The new native SMBIOS decoder at _os/src/app/smbios_decoder_ can be used on
x86 to parse SMBIOS tables and report gathered information in a human-readable
way. Besides general table information like number and size of structures,
etc., the component supports complete parsing of SMBIOS structures of types
"BIOS", "System", and "Baseboard".
The component is free from any code for acquiring an SMBIOS table through
means like the bootloader or BIOS information. It expects a table to be
present through a regular Genode ROM session with a 'smbios_table' label. This
way, the underlying system is required to find, select, and save the raw table
on startup and create a ROM module out of it. This is currently achieved on
NOVA and base-hw through an interplay of kernel, the core component, and the
ACPI driver and was tested for legacy BIOSes as well as UEFI systems.
Clipboard
=========
Genode introduced a principle copy-and-paste mechanism already
[https://genode.org/documentation/release-notes/15.11#Copy_and_paste - four years ago].
However, originally created as a part of a tech demo, the mechanism remained
unused in our day to day Genode work. This changed now. We took the
integration of copy-and-paste support in Sculpt OS as an opportunity to revive
and refine the existing mechanism and supplement it with the features needed
to make it practical for daily use. We believe that the result aligns ease of
use nicely with security. The concept is described in a
[https://genodians.org/nfeske/2019-07-03-copy-paste - dedicated article]
at Genodians.org.
On a technical level, the existing clipboard component has received a new
option that allows for dynamic information-flow policies based on user
interactivity (keyboard focus, activity). When setting the config attribute
'match_labels="yes"', the clipboard performs plausibility checks for copy and
paste operations against the focus of the Nitpicker GUI server. All aspects of
the clipboard policy - including information-flow policies - have become
reconfigurable.
To make window-manager clients compatible with the clipboard's dynamic policy,
the window manager got enhanced with the ability to proxy the interaction with
the clipboard. GUI clients in turn - in particular the graphical *terminal* -
became able to interact with the clipboard. With the '<config>' attribute
'copy="yes"' specified, the terminal allows the user to select text to be
reported to a "clipboard" report. The selection mode is activated by holding
the left shift key. While the selection mode is active, the text position
under the mouse pointer is highlighted and the user can select text via the
left mouse button. Upon release of the mouse button, the selection is
reported. Vice versa, with the '<config>' attribute 'paste="yes"' specified,
the terminal allows the user to paste the content of a "clipboard" ROM session
to the terminal client by pressing the middle mouse button.
Finally, we integrated those new abilities into Sculpt OS and into several
installable packages, including virtual machines, the noux-system package,
and graphical Qt5-based applications.
Enhanced SSH terminal
=====================
This release paves the way for remotely managing Genode devices over SSH.
Until now, only interactive SSH sessions were supported. It is now possible to
execute commands from a remote SSH client. E.g., 'ssh noux@localhost -p 5555
"ls -hal /bin/"'. For non-interactive sessions, ssh_terminal requires a helper
component. This component is responsible to create the environment for the
command to run in. You can find an example for such a component at
_gems/src/test/exec_terminal_. It starts noux in a sub init and executes the
provided command inside of it. The new _ssh_exec_channel.run_ script gives a
demonstration on how this feature can be used.
This work is a contribution by Sid Hussmann of
[https://gapfruit.com - Gapfruit]. Thanks for this great new feature!
Storage-stack improvements
==========================
The desire of one Genode developer to exchange data via Iomega ZIP drives
between an Atari Falcon and Sculpt OS called for a number of small
improvements across several components of the storage stack.
First, the USB-block driver has been changed to exit on an initialization
failure instead of waiting for another (supported) device. This change enables
the Sculpt manager to detect such conditions and release the USB device
hardware by removing the driver component. Such a failed initialization may
happen with exotic USB-storage devices such as ZIP drives. With the device
released, however, it can be assigned to a virtual machine to access it using
a guest OS with a broader support of devices.
Second, the USB-block driver received new support for issuing the SCSI
START-STOP command at initialization time, thereby overcoming the ZIP-drive
initialization failure.
Third, we enhanced the part-block component with the ability to parse AHDI
partition schemes and detect the GEMDOS variant of FAT as used by Atari TOS.
Fourth, we enabled the Rump VFS plugin to access GEMDOS file systems. The
GEMDOS variant is readily supported by NetBSD's "msdos" file-system driver.
However, it must explicitly be enabled by a mount flag. Hence, we added the
principle ability for passing mount flags to NetBSD file-system drivers and
enabled the MSDOSFSMNT_GEMDOSFS flag based on the VFS plugin's config
attribute 'gemdos="yes"'.
With these changes in place, data can now be exchanged directly between
Atari-formatted disks and Sculpt OS. That said, advanced use cases such as
media changes at runtime are not covered yet.
Updated Ada/SPARK runtime
=========================
Genode's Ada/SPARK runtime is developed and maintained by
[https://componolit.com - Componolit]. Thanks for this excellent
collaboration!
The updated Componolit Ada runtime 1.1.0 increases the proof coverage and
cleans up the source-code structure. SPARK mode is now enabled wherever
possible and unneeded abstractions have been removed. Furthermore, the 64-bit
addition and subtraction have been proven to be free of runtime errors.
As a new feature, the runtime now supports the use of inline assembly in Ada.
The removal of unneeded features such as the incomplete threading support for
the secondary stack has greatly reduced the runtime's complexity while keeping
the current functionality available. Also GNAT.IO has been removed as its
implementation was incomplete and complex. A simpler replacement has been
introduced with 'Componolit.Runtime.Debug'.
Unrelated to Genode, the runtime now supports [https://muen.sk/ - Muen] and
the API/ABI of the runtime has been separated from the GNAT ABI.
Libraries and applications
##########################
Updated Qt5
===========
We updated our Qt5 port to the latest upstream version 5.13.0. Before
preparing the 'qt5' port, please make sure to build and install the updated
Qt5 host tools with the 'tool/tool_chain_qt5' script.
Virtualization
==============
As follow-up of our work on the
[https://genode.org/documentation/release-notes/19.05#Kernel-agnostic_virtual-machine_monitors - kernel agnostic virtual-machine monitor interface]
on x86, we added principle support to run our port of VirtualBox on
Genode/Fiasco.OC. We write _principle_ support, since we managed to get the
VMM running with Fiasco.OC, but unfortunately not all features required by the
VMM are available using the Fiasco.OC kernel, e.g., guest FPU registers, PDPTE
registers, and task-priority support. In practice this means that the VMs with
Windows and Linux come up to a certain point but will fail later whenever the
guest state runs out of synchronization between VMM and hardware. In contrast,
the Seoul VMM runs fine on Fiasco.OC since it does not depend on the mentioned
missing features.
Our main working items have been the completion of transfer of the available
guest registers and control flow synchronization improvements between VMM and
Fiasco.OC kernel. Additionally, the usage of priorities for VirtualBox's
pthreads in the VMM had to be disabled. Finally, some tests for VirtualBox
with Genode/Fiasco.OC are enabled for nightly regular testing now.
As a side topic, we added support for using the VirtualBox
[https://forums.virtualbox.org/viewtopic.php?f=2&t=82299&start=15 - CPU profile]
feature, which allows for presenting a different CPUID to the VM than the one
of the real CPU. This can help when running Windows 7 on a Kaby Lake or newer
CPU, which are considered _unsupported hardware_ and reason enough not to
receive security updates from Microsoft. The feature can be used on Genode by
adding the 'CpuProfile' attribute to the '<CPU>' XML node in the .vbox file,
like:
! <CPU CpuProfile="Intel Core i7-5600U">
Disposable VM for handling captive portals
==========================================
It is common that WiFi networks require the user to interact with a specific
web page before gaining access to full network functionality. Such captive
portal pages are completely individual to the accessed network and not limited
in the use of common web techniques. Therefore, their handling is best be done
using a fully-featured web browser like Mozilla Firefox.
This is where, in a Genode-based desktop system like Sculpt, a disposable VM
for hosting a minimal browser setup becomes desirable. Its goal is to unlock a
network for the native Genode surroundings with as little inconvenience as
possible just to be thrown away afterwards without any side effects on the
system.
Now, one could use the Firefox appliance VM of Sculpt (see the
[https://genode.org/documentation/release-notes/18.05 - release notes] or the
[http://genodians.org/alex-ab/2019-03-06-disposal-browser-vm - Genodians article])
for this. But this VM aims for a long-term browsing experience which, in the
context of mere captive-portal handling, brings some drawbacks like a much
higher RAM consumption or the required sessions for USB detection and shared
folders.
Furthermore, in the captive portal VM, there's no need for managing windows or
browser tabs. The one browser tab needed can always be shown in fullscreen. It
is also unnecessary for the browser to maintain a content cache or remember
user data. This can reduce resource consumption.
[image captive_portal_vm]
The VM we came up with is provided as package for Sculpt by Martin Stein
(depot user 'mstein'). You'll possibly need to manually add Martin's
[https://github.com/genodelabs/genode/tree/master/depot/mstein - depot key and download location]
to your Sculpt depot directory. After enabling this user, the captive portal
VM can be found in the Sculpt menu under "Depot -> mstein -> Virtual
Machines -> vbox5-nova-captive-portal".
The VM is based on a TinyCore 10 Linux with Xserver, i3 WM, and a tailored
Firefox browser. The package runtime doesn't need access to your file system,
it merely loads some ROMs into a RAM FS, so, it will completely forget any
changes made during a session. Therefore, it's also safe to simply remove an
instance via the Leitzentrale component-view once you don't need it anymore.
The guest additions are also included to make the VM window resizable.
Build system and tools
######################
At Genode Labs, we have used _tool/autopilot_ for the steering of tests in our
Continuous Integration workflow for almost a decade now. This implied various
improvements over the years and with the completion of our work on
[https://genode.org/documentation/release-notes/19.05#Unified_build_directories_for_ARM - unified build directories]
it was time to amend this handy tool once again. Unified build directories
support building all components for one CPU architecture in one directory
saving the build server from the redundant work we previously had with
board-specific directories. With the new notion of boards during builds, the
definition of the target platform when integrating Genode system scenarios is
now a triplet of _CPU architecture_, _board_, and _kernel_. This is reflected
in the new '-t <architecture-board-kernel>' command line option, which
instructs autopilot to generate a build directory for _architecture_ and
execute tests for the _board-kernel_ combination.
! autopilot -t x86_64-pc-sel4 -t x86_64-pc-nova -r run/log
The known options for '-k kernel' and '-p platform' are still supported with
the small change that the platform must now be defined as
_architecture-board_.
! autopilot -p x86_64-pc -k sel4 -k nova -r run/log
Autopilot now also documents the hidden feature to propagate custom 'RUN_OPTs'
via the 'RUN_OPT_AUTOPILOT' environment variable to the run tool executed.
Besides that, the tool always appends 'RUN_OPT' with '--autopilot'.
! RUN_OPT_AUTOPILOT="--depot-dir /data/depot" autopilot ...

===============================================
Release notes for the Genode OS Framework 19.11
===============================================
Genode Labs
On our [https://genode.org/about/road-map - road map] for this year, we stated
"bridging worlds" as our guiding theme of 2019. The current release pays
tribute to this ambition on several accounts.
First, acknowledging the role of POSIX in the real world outside the heavens
of Genode, the release vastly improves our (optional) C runtime with respect
to the emulation of POSIX signals, execve, and ioctl calls. With the line of
work described in Section [C runtime with improved POSIX compatibility], we
hope to greatly reduce the friction when porting and hosting existing
application software directly on Genode.
Second, we identified the process of porting or developing application
software worth improving. Our existing tools were primarily geared to
operating-system development, not application development. Application
developers demand different work flows and tools, including the freedom to use
a build system of their choice.
Section [New tooling for bridging existing build systems with Genode]
introduces our new take on this productivity issue.
Third, in cases where the porting of software to Genode is considered
infeasible, virtualization comes to the rescue. With the current release, a
new virtual machine monitor for the 64-bit ARM architecture enters the
framework. It is presented in Section [Virtualization of 64-bit ARM platforms].
As another goal for 2019, we envisioned a solution for block-level device
encryption, which is a highly anticipated feature among Genode users. We are
proud to present the preliminary result of our year-long development in
Section [Preliminary block-device encrypter].
Preliminary block-device encrypter
##################################
Over the past year, we worked on implementing a block-device encryption
component that makes use of the
[https://en.wikipedia.org/wiki/SPARK_(programming_language) - SPARK]
programming language for its core logic. In contrast to common
block-device encryption techniques where normally is little done besides
the encryption of the on-disk blocks, the _consistent block encrypter (CBE)_
aims for more. It combines multiple techniques to ensure integrity -
the detection of unauthorized modifications of the block-device -
and robustness against data loss. Robustness is achieved by keeping snapshots
of old states of the device that remain unaffected by the further operation of
the device. A copy-on-write mechanism (only the differential changes to the
last snapshot are stored) is employed to maintain this snapshot history with
low overhead. To be able to access all states of the device in the same manner,
some kind of translation from virtual blocks to blocks on the device is needed.
Hash-trees, where each node contains the hash of its sub-nodes, combine the
aspect of translating blocks and ensuring their integrity in an elegant way.
During the tree traversal, the computed hash of each node can be easily checked
against the hash stored in the parent node.
The CBE does not perform any cryptography by itself but delegates
cryptographic operations to another entity. It neither knows nor cares about
the used algorithm. Of all the nodes in the virtual block device (VBD), only
the leaf nodes, which contain the data, are encrypted. All other nodes, which
only contain meta-data, are stored unencrypted.
Design
------
As depicted in Figure [cbe_trees], all information describing the various
parts of the CBE is stored in the superblock. The referenced VBD is a set of
several hash trees, each representing a certain device state including the
current working state. Only the tree of the current working state is used to
write data to the block device. All other trees represent snapshots of older
states and are immutable. Each stored device state has a generation number
that provides the chronological order of the states.
As you can see, in the depicted situation, there exist four device states - the
snapshot with generation 3 is the oldest, followed by two newer snapshots and
generation 6 that marks the working state of the virtual device. The tree with
generation 6 is the current working tree. Each tree contains all changes done
to the VBD since the previous generation (for generation 6 the red nodes). All
parts of a tree that didn't change since the previous generation are references
into older trees (for generation 6 the gray nodes). Note that in the picture,
nodes that are not relevant for generation 6 are omitted to keep it manageable.
The actual data blocks of the virtual device are the leaf nodes of the trees,
shown as squares.
[image cbe_trees]
Whenever a block request from the client would override data blocks in
generation 6 that are still referenced from an older generation, new blocks for
storing the changes are needed. Here is where the so-called _Free Tree_ enters
the picture. This tree contains and manages the spare blocks. Spare blocks are
a certain amount of blocks that the CBE has in addition to the number of blocks
needed for initializing the virtual device. So, after having initialized a
virtual device, they remain unused and are only referenced by the Free Tree.
Therefore, in case the VBD needs new blocks, it consults the Free Tree (red
arrow).
In the depicted situation, writing the first data block (red square) would
require allocating 4 new blocks as all nodes in the branch leading to the
corresponding leaf node - including the leaf node itself - have to be written.
In contrast, writing the second data block would require allocating only one
new block as the inner nodes (red circles) now already exist. Subsequent write
requests affecting only the new blocks will not trigger further block
allocations because they still belong to the current generation and will be
changed in-place. To make them immutable we have to create a new snapshot.
The blocks in generation 5 that were replaced by the change to generation 6
(blue nodes) are not needed for the working state of the virtual device
anymore. They are therefore, in exchange for the allocated blocks, added to
the Free Tree. But don't be fooled by the name, they are not free for
allocation yet, but marked as "reserved" only. This means, they are
potentially still part of a snapshot (as is the case in our example) but the
Free Tree shall keep checking, because once all snapshots that referenced the
blue blocks have disappeared, they become free blocks and can be allocated
again.
To create a new snapshot, we first have to make all changes done to the VBDs
working state as well as the Free Tree persistent by writing all corresponding
blocks to the block-device. After that, the new superblock state is written to
the block-device. To safeguard this operation, the CBE always maintains several
older states of the superblock on the block device. In case writing the new
state of the superblock fails, the CBE could fall back to the last state that,
in our example, would contain only generations 3, 4, and 5. Finally, the
current generation of the superblock in RAM is incremented by one (in the
example to generation 7). Thereby, generation 6 becomes immutable.
A question that remains is when to create snapshots. Triggering a snapshot
according to some heuristics inside the CBE might result in unnecessary
overhead. For instance, the inner nodes of the tree change frequently during a
sequential operation. We might not want them to be re-allocated all the time.
Therefore, the creation of a snapshot must be triggered explicitly from the
outside world. This way, we can accommodate different strategies, for
instance, client-triggered, time-based, or based on the amount of data
written.
When creating a snapshot, it can be specified whether it shall be disposable
or persistent. A disposable snapshot will be removed automatically by the CBE
in two situations, either
* When there are not enough usable nodes in the Free Tree left to
satisfy a write request, or
* When creating a new snapshot and all slots in the superblock that might
reference snapshots are already occupied.
A persistent snapshot, or quarantine snapshot, on the other hand will never be
removed automatically. Its removal must be requested explicitly.
During initialization, the CBE selects the most recent superblock and reads the
last generation value from it. The current generation (or working state
generation) is then set to the value incremented by one. Since all old blocks,
that are still referenced by a snapshot, are never changed again, overall
consistency is guaranteed for every generation whose superblock was stored
safely on disk.
Implementation
--------------
Although we aimed for a SPARK implementation of the CBE, we saw several
obstacles with developing it in SPARK right from the beginning. These obstacles
mainly came from the fact that none of us was experienced in designing
complex software in SPARK. So we started by conducting a rapid design-space
exploration using our mother tongue (C++) while using only language features
that can be mapped 1:1 to SPARK concepts. Additionally, we applied a clear
design methodology that allowed us to keep implementation-to-test cycles
small and perform a seamless and gradual translation into SPARK:
* _Control flow_
The core logic of the CBE is a big state machine that doesn't block. On each
external event, the state machine gets poked to update itself accordingly.
C++ can call SPARK but SPARK never calls C++. The SPARK code therefore
evolves as self-contained library.
* _Modularity_
The complex state machine of the CBE as a whole is split-up into smaller
manageable sub-state-machines, working independently from each other. These
modules don't call each other directly. Instead, an additional superior
module handles the interplay. This is done by constantly iterating over all
modules with the following procedure until no further progress can be made:
# Try to enter requests of other modules into the current one
# Poke the state machine of the current module
# The current module may have generated requests - Try to enter them into
the targeted modules
# The current module may have finished requests - Acknowledge them at the
modules they came from
Each module is represented through a class (C++) respectively a package with
a private state record (SPARK).
* _No global state_
There are no static (C++) or package (SPARK) variables. All state is kept in
members of objects (C++) respectively records (SPARK). All packages are pure
and sub-programs have no side-effects. Therefore, memory management and
communication with other components is left to OS glue-code outside the
core logic.
This approach worked out well. Module by module, we were able to translate the
C++ prototype to SPARK without long untested phases, rendering all regression
bugs manageable. In Genode, the CBE library is currently integrated through
the CBE-VFS plugin. Figure [cbe_modules] depicts its current structure and the
integration via VFS plugin.
[image cbe_modules]
The green and blue boxes each represent an Ada/SPARK package. The translation
to SPARK started at the bottom of the picture moving up to the more abstract
levels until it reached the Library module. This is the module that handles
the interplay of all other modules. Its interface is the front end of the CBE
library. So, all green packages are now completely written in SPARK and
together form the CBE library. Positioned above, the CXX library in blue is
brought in by a separate library and exports the CBE interface to C++. This
way, the CBE can also be used in other environments including pure SPARK
programs. The CXX Library package is not written in SPARK but Ada and performs
all the conversions and checks required to meet the preconditions set by the
SPARK packages below.
At the C++ side, we have the VFS plugin. Even at this level, the already
mentioned procedure applies: The plugin continuously tries to enter requests
coming from the VFS client (above) into the CBE (below), pokes the CBE state
machine, and puts thereby generated block/crypto requests of the CBE into the
corresponding back-ends (left). This process is repeated until there is no
further progress without waiting for an external event.
Current state
-------------
In its current state, the CBE library is still pretty much in flux and is not
meant for productive use.
As the Free Tree does not employ copy-on-write semantics for its meta-data, a
crash, software- or hardware-wise, will corrupt the tree structure and renders
the CBE unusable on the next start.
This issue is subject to ongoing work. That being said, there are
components that, besides being used for testing, show how the interface of the
CBE library lends itself to be integrated in components in different ways. At
the moment, there are two components making use of the CBE library as
block-device provider.
The first one is the aforementioned CBE-VFS plugin. Besides r/w access to the
working tree and r/o access to all persistent snapshots, it also provides a
management interface where persistent snapshots can be created or discarded.
Its current layout is illustrated by Figure [cbe_vfs]. The VFS plugin
generates three top directories in its root directory. The first one is the
_control_ directory. It contains several pseudo files for managing the CBE:
[image cbe_vfs]
:'key': set a key by writing a string into the file.
:'create_snapshot': writing 'true' to this file will attempt to create
a new snapshot. (Eventually the snapshot will
appear in the 'snapshots' directory if it could be
created successfully.)
:'discard_snapshot': writing a snapshot ID into this file will discard
the snapshot
The second is the 'current' directory. It gives access to the current
working tree of the CBE and contains the following file:
:'data': this file represents the virtual block device and gives
read and write access to the data stored by the CBE.
The third and last is the 'snapshots' directory. For each persistent snapshot,
there is a sub-directory named after the ID of the snapshot. This directory,
like the 'current' directory, contains a 'data' file. This file, however,
gives only read access to the data belonging to the snapshot.
The CBE-VFS plugin itself uses the VFS to access the underlying block device.
It utilizes the file specified in its configuration. Here is a '<vfs>'
snippet that shows a configured CBE-VFS plugin where the block device is
provided by the block VFS plugin.
! <vfs>
! <dir name="dev">
! <block name="block"/>
! <cbe name="cbe" block="/dev/block"/>
! </dir>
! </vfs>
An exemplary ready-to-use run script can be found in the CBE repository
at _run/cbe_vfs_snaps.run_. This run script uses a bash script to
automatically perform a few operations on the CBE using the VFS plugin.
Afterwards it will drop the user into a shell where further operations
can be performed manually, e.g.:
! dd if=/dev/zero of=/dev/cbe/current/data bs=4K
The second component is the CBE server. In contrast to the CBE-VFS plugin,
it is just a simple block-session proxy component that uses a block connection
as back end to access a block-device. It provides a front-end block session to
its client, creates disposable snapshots every few seconds, and uses the
'External_Crypto' library to encrypt the data blocks using AES-CBC-ESSIV. The
used key is a plain passphrase. The following snippet illustrates its
configuration:
! <start name="cbe">
! <resource name="RAM" quantum="4M"/>
! <provides><service name="Block"/></provides>
! <config sync_interval="5" passphrase="All your base are belong to us"/>
! </start>
The _run/cbe.run_ run script in the CBE repository showcases the use of the
CBE server.
Both run scripts will create the initial CBE state in a RAM-backed
block device that is then accessed by the CBE server or the CBE-VFS
plugin.
The run-script and the code itself can be found on the
[https://github.com/cnuke/cbe/tree/cbe_19.11 - cbe/cbe_19.11] branch on
GitHub. If you intend to try it out, you have to checkout
the corresponding
[https://github.com/cnuke/genode/tree/cbe_19.11 - genode/cbe_19.11]
branch in the Genode repository as well.
Future plans
------------
Besides addressing the current shortcomings and getting the CBE library
production-ready so that it can be used in Sculpt, there are still
a few features that are currently unimplemented. For one we would like
to add support for making it possible to resize the VBD as well as the
Free Tree. For now the geometry is fixed at initialization time and cannot
be changed afterwards. Furthermore, we would like to enable re-keying,
i.e., changing the used cryptographic key and re-encrypting the tree
set of the VBD afterwards. In addition to implementing those features, the
overall tooling for the CBE needs to be improved. E.g., there is currently
no proper initialization component. For now, we rely on a component
that was built merely as a test vehicle to generate the initial trees.
Virtualization of 64-bit ARM platforms
######################################
Genode has a long history regarding support of all kinds of
virtualization-related techniques including
[https://genode.org/documentation/release-notes/9.11#Paravirtualized_Linux_on_Genode_OKL4 - para-virtualization],
[https://genode.org/documentation/articles/trustzone - TrustZone],
hardware-assisted virtualization on
[https://genode.org/documentation/articles/arm_virtualization - ARM],
[https://genode.org/documentation/release-notes/13.02#Full_virtualization_on_NOVA_x86 - x86],
up to the full virtualization stack of
[https://genode.org/documentation/release-notes/14.02#VirtualBox_on_top_of_the_NOVA_microhypervisor - VirtualBox].
We regard those techniques as welcome stop-gap solutions for using non-trivial
existing software stacks on top of Genode's clean-slate OS architecture. The
[https://genode.org/documentation/release-notes/19.05#Kernel-agnostic_virtual-machine_monitors - recent]
introduction of a kernel-agnostic interface to control virtual machines (VM)
ushered a new level for the construction respectively porting of
virtual-machine monitors (VMM). By introducing a new ARMv8-compliant VMM
developed from scratch, we continue this line of work.
The new VMM builds upon our existing proof-of-concept (PoC) implementation for
ARMv7 as introduced in release
[https://genode.org/documentation/release-notes/15.02#Virtualization_on_ARM - 15.02].
In contrast to the former PoC implementation, however, it aims to be complete
to a greater extent. Currently, it comprises device models for the following
virtual hardware:
* RAM
* System Bus
* CPU
* Generic Interrupt Controller v2 and v3
* Generic Timer
* PL011 UART (limited)
* Pass-through devices
The VMM is able to load diverse 64-bit Linux kernels including
Device-Tree-Binary (DTB) and Initramfs. Currently, the implementation uses a
fixed memory layout for the guest-physical memory view, which needs to be
reflected by the DTB used by the guest OS. An example device-tree source file
can be found at _repos/os/src/server/vmm/spec/arm_v8/virt.dts_. The actual VMM
is located in the same directory.
Although support for multi-core VMs is already considered internally, it is
not yet finished. Further outstanding features that are already in development
are Virtio device model support for networking and console. As the first - and
by now only - back end, we tied the VMM to the ARMv8 broadened Kernel-agnostic
VM-session interface as implemented by Genode's custom base-hw kernel. As a
side effect of this work, we consolidated the generic VM session interface
slightly. The RPC call to create a new virtual-CPU now returns an identifier
for identification.
The VMM has a strict dependency on ARM's hardware virtualization support
(EL2), which comprises extensions for the ARMv8-A CPU, ARM's generic timer,
and ARM's GIC. This rules out the Raspberry Pi 3 board as a base platform
because it does not include a GIC but a custom interrupt-controller without
hardware-assisted virtualization of interrupts. To give the new VMM a try, we
recommend using the run script _repos/os/run/vmm_arm.run_ as a starting point
for executing the VMM on top of the i.MX8 Evaluation Kit board.
New tooling for bridging existing build systems with Genode
###########################################################
Genode's development tools are powerful and intimidating at the same time.
Being designed from the perspective of a whole-systems developer, they put
emphasis on the modularity of the code base (separating concerns like
different kernels or system abstraction levels), transitive dependency
tracking between libraries, scripting of a wide variety of system-integration
tasks, and the continuous integration of complete Genode-based
operating-system scenarios. Those tools are a two-edged sword though.
On the one hand, the tools are key for the productivity of seasoned Genode
developers once the potential of the tools is fully understood and leveraged.
For example, during the development of Sculpt OS, we are able to
change an arbitrary line of code in any system component and can test-drive
the resulting Sculpt system on real hardware within a couple of seconds.
As another example, the almost seamless switching from one OS kernel to
another has become a daily routine that we just take for granted without
even thinking about it.
On the other hand, the sophistication of the tools stands in the way of
application developers who are focused on a particular component instead
of the holistic Genode system. In this case, the powerful system-integration
features remain unused but the complexity of the tools and the build system
prevails. Speaking of build systems, this topic is ripe of emotions
anyway. _Developers use to hate build systems._ Forcing Genode's build
system down the throats of application developers is probably not the best
idea to make Genode popular.
This line of thoughts prompted us to re-approach the tooling for Genode from
the perspective of an application developer. The intermediate result is a new
tool called Goa:
:Goa project at GitHub:
[https://github.com/nfeske/goa]
Unlike Genode's regular tools, Goa's work flow is project-centered. A project
is a directory that may contain source code, data, instructions how to
download source codes from a 3rd party, descriptions of system scenarios, or
combinations thereof. Goa is independent from Genode's regular build system.
It combines Genode's package management (depot) with commodity build systems
such a CMake. In addition to building and test-driving application software
directly on a Linux-based development system, Goa is able to aid the process
of exporting and packaging the software in the format expected by Genode
systems like Sculpt OS.
At the current stage, Goa should be considered as work in progress. It's a new
approach and its success is anything but proven. That said, if you are
interested in developing or porting application software for Genode, your
feedback would be especially valuable. As a starting point, you may find the

Base framework and OS-level infrastructure
##########################################
File-system session
===================
The file-system session interface received a much anticipated update.
Writing modification times
--------------------------
The new operation WRITE_TIMESTAMP allows a client to update the modification
time of a file-system node. The time is defined by the client to keep
file-system servers free from time-related concerns. The VFS server implements
the operation by forwarding it to the VFS plugin interface. At present, this
new interface is implemented by the rump VFS plugin to store modification
times on EXT2 file systems.
Enhanced file-status info
-------------------------
The status of a file-system node as returned by the 'File_system::Status'
operation has been revisited. First, we replaced the fairly opaque "mode" bits -
which were an ad-hoc attempt to stay compatible with Unix - with the explicit
notion of 'readable', 'writeable', and 'executable' attributes. We completely
dropped the notion of users and groups. Second, we added the distinction
between *continuous* and *transactional* files to allow for the robust
implementation of continuous write operations across component boundaries. A
continuous file can be written-to via a sequence of arbitrarily sized chunks
of data. For such files, a client can split a large write operation into any
number of smaller operations in accordance to the size of the used I/O
buffers. In contrast, a write to a transactional file is regarded as a
distinct operation. The canonical example of a transactional file is a
socket-control pseudo file.
Virtual file-system infrastructure
==================================
First fragments of a front-end API
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The VFS is mostly used indirectly via the C runtime. However, it is also
useful for a few components that use the Genode API directly without any
libc. To accommodate such users of the VFS, we introduced the front-end
API at _os/vfs.h_ that covers a variety of current use cases. Currently, those
use cases revolve around the watching, reading, and parsing of files and
file-system structures - as performed by Sculpt's deployment mechanism.
Writing to files is not covered.
Improved file-watching support
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
All pseudo files that use the VFS-internal 'Readonly_value_file_system'
utility have become able to deliver watch notifications. This change enables
VFS clients to respond to VFS-plugin events (think of terminal resize)
dynamically.
Speaking of the *terminal VFS plugin*, the current release enhances the plugin
in several respects. First, it now delivers status information such as the
terminal size via pseudo files. Second, we equipped the VFS terminal file
system with the ability to detect user interrupts in the incoming data stream,
and propagate this information via the new pseudo file '.terminal/interrupts'.
Each time, the user presses control-c in the terminal, the value stored in
this pseudo file is increased. Thereby, a VFS client can watch this file to
get notified about the occurrences of user interrupts.
VFS plugin for emulating POSIX pipes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We added a new VFS plugin for emulating POSIX pipes. The new plugin creates
pipes between pairs of VFS handles. It replaces the deprecated libc_pipe
plugin. In contrast to the libc_pipe plugin, which was limited to pipes within
one component, the new VFS plugin can also be used to establish pipes between
different components by mounting the plugin at a shared VFS server.
C runtime with improved POSIX compatibility
===========================================
Within Genode, we used to think of POSIX as a legacy that is best avoided.
In fact, the foundational components of the framework do not depend on a
C runtime at all. However, higher up the software stack - at the latest when
3rd-party libraries enter the picture - a working C runtime is unavoidable. In
this statement, the term "working" is rather muddy though. Since we have never
fully embraced POSIX, we were content with cutting corners here and there. For
example, given Genode's architecture, supporting 'fork' and 'execve' seemed
totally out of question because those mechanisms would go against the grain of
Genode.
However, our growing aspiration to bridge the gap between existing popular
applications and Genode made us re-evaluate our stance towards POSIX.
All technical criticism aside, POSIX is immensely useful because it is
a universally accepted stable interface. To dissolve friction between
Genode and popular application software, we have to satisfy the application's
expectations. This ignited a series of developments, in particular
the added support for 'fork' and 'execve' - of all things - in
[https://genode.org/documentation/release-notes/19.08#Consolidation_of_the_C_runtime_and_Noux - Genode 19.08],
which was nothing short of surprising, even to us.
The current release continues this line of development and brings the
following improvements.
Execve
------
The libc's 'execve' implementation got enhanced to evaluate the path of the
executable binary according to the information found on the VFS, in particular
by traversing directories and following symbolic links. This enables the libc
to execute files stored at sub directories of the file system.
Furthermore, 'execve' received handling for *executing shell scripts* by
parsing the shebang marker at the beginning of the executable file. This way,
the 'execve' mechanism of the libc reaches parity with the feature set of the
Noux runtime that we traditionally used to host Unix software on top of
Genode.
Modification-time handling
--------------------------
By default, the libc uses the just added facility for updating the timestamp
of file-system nodes when closing a written-to file, which clears the path
towards using tools like 'make' that rely on file-modifications times.
The libc's mechanism can be explicitly disabled by specifying
! <libc update_mtime="no"...>
This is useful for applications that have no legitimate access to a time
source.
Emulation of 'ioctl' operations via pseudo files
------------------------------------------------
With the current release, we introduce a new scheme of handling ioctl
operations, which maps 'ioctl' calls to pseudo-file accesses, similar to how
the libc already maps socket calls to socket-fs operations.
A device file can be accompanied with a (hidden) directory that is named after
the device file and hosts pseudo files for triggering the various device
operations. For example, for accessing a terminal, the directory structure
looks like this:
! /dev/terminal
! /dev/.terminal/info
! /dev/.terminal/rows
! /dev/.terminal/columns
! /dev/.terminal/interrupts
The 'info' file contains device information in XML format. The type of the XML
node corresponds to the device type. Whenever the libc receives a TIOCGWINSZ
ioctl for _/dev/terminal_, it reads the content of _/dev/.terminal/info_ to
obtain the terminal-size information. In this case, the _info_ file looks as
follows:
! <terminal rows="25" columns="80/>
Following this scheme, VFS plugins can support ioctl operations by providing
an ioctl directory in addition to the actual device file.
Emulation of POSIX signals
--------------------------
Even though there is no notion of POSIX signals at the Genode level, we
can reasonably emulate certain POSIX signals at the libc level. The current
release introduces the first bunch of such emulated signals:
:SIGWINCH: If 'stdout' is connected to a terminal, the libc watches the
terminal's ioctl pseudo file _.terminal/info_. Whenever the terminal
size changes, the POSIX signal SIGWINCH is delivered to the application.
With this improvement, Vim becomes able to dynamically adjust itself
to changed window dimensions when started as a native Genode component
(w/o the Noux runtime environment).
:SIGINT: If 'stdin' is connected to a terminal, the libc watches the
terminal's pseudo file _.terminal/interrupts_. Since, the terminal VFS
plugin modifies the file for each occurred user interrupt (control-c),
the libc is able to reflect such an event as SIGINT signal to the
application.
:Process-local signal delivery: The libc's implementation of 'kill' got
enhanced with the ability to submit signals to the local process.
Support for arbitrarily large write operations
----------------------------------------------
The number of bytes written by a single 'write' call used to be constrained by
the file's underlying I/O buffer size. Even though our libc correctly returned
this information to the application, we found that real-world applications
rarely check the return value of 'write' because partial writes do usually not
occur on popular POSIX systems. Thanks to the added distinction between
continuous and transactional files as described in Section
[File-system session], we became able to improve the libc's write operation to
iterate on partial writes to continuous files until the original write count
is reached. The split of large write operations into small partial writes as
dictated by the VFS infrastructure becomes invisible to the libc-using
application.
Input-event handling
====================
In Genode 19.08, we undertook a comprehensive rework of our keyboard-event
handling in the light of localization and also promised to tie up remaining
loose ends soon.
First, we again dived into our character generators for a thorough check of
our stack of keyboards and fixed remaining inconsistencies in French and
German layouts. En passant, we also increased the default RAM quotas for
the input filter to 1280K in our recipes to cope with the increased
layout-configuration sizes in corner cases.
Next - and more importantly - we subdued the monsters lurking in our Qt5
keyboard back end and enabled transparent support for system-wide keyboard
layout configuration for Qt5 components. One important change during this work
was to move the handling of control key sequences into the clients. For
example, the graphical terminal and Qt5 interpret key events in combination
with the CTRL modifier based on characters and, thus, support CTRL-A with
AZERTY and QWERTY layouts correctly. As a result we removed all CTRL modifier
(mod2) configurations from our character-generator configurations.
Finally we'd like to point out one important change of our rework that
repeatedly led to surprises: For keys without character mappings the reworked
character-generator mechanism emits invalid codepoints in contrast to
codepoints with value 0. For that reason, components interpreting character
events should check 'Codepoint::valid()' to prevent the processing of invalid
characters (and not the frequent pattern of 'codepoint.value != 0').
NIC router
==========
The NIC router has received the ability to report the link state of its NIC
interfaces (downlinks and uplinks). To control this mechanism, there are two
new boolean attributes 'link_state' and 'link_state_triggers' in the <report>
tag of the NIC router configuration. If the former is set to "true", the report
will contain the current link state for each interface:
! <domain name="domain1">
! <interface label="uplink1" link_state="false"/>
! <interface label="downlink1" link_state="true"/>
! </domain>
! <domain name="domain2">
! <interface label="downlink2" link_state="true"/>
! </domain>
The second attribute decides whether to trigger a report update each time the
link state of an interface changes. By default, both attributes are set to
"false".
Device drivers
==============
Platform driver on x86
~~~~~~~~~~~~~~~~~~~~~~
During our enablement of Genode on a
[https://genodians.org/chelmuth/2019-10-21-sculpt-elitebook - recent notebook],
we spotted some PC platform shortcomings, we address with this release. Most
prominently we added support for
[https://en.wikipedia.org/wiki/PCI_configuration_space#Bus_enumeration - 64-bit PCI base address registers]
to the x86 platform driver. This allows the use of PCI devices that are
assigned to physical I/O-memory regions beyond 4 GiB by the boot firmware.
Wireless driver
~~~~~~~~~~~~~~~
We added the firmware images for the 5000 and 9000 series of Intel wireless
devices to the firmware white-list in the _wifi_drv_ component. Such devices
as 5100AGN, 5300AGN and 5350AGN as well as 9461, 9462 and 9560 should now be
usable on Genode.
Libraries and applications
##########################
VirtualBox improvements
=======================
The GUI handling of our VirtualBox port got improved to react on window-size
changes more instantly. The effect is that an interactive adjustment of the
window size, e.g., on Sculpt, becomes quickly visible to the user. Still, the
VM may take some time to adjust to the resolution change, which ultimately
depends on the behavior of the driver of the VirtualBox guest additions.
Updated 3rd-party software
==========================
With the addition of the 64-bit ARM architecture (AARCH64) with the
[https://genode.org/documentation/release-notes/19.05#Broadened_CPU_architecture_support_and_updated_tool_chain - 19.05]
release, it became necessary to update the libraries the Genode tool chain
(gcc) depends on in order to support AARCH64 properly. This concerns the GNU
multi precision arithmetic library (gmp), which has been updated from version
4.3.2 to 6.1.2, as well as the libraries that depend on it: Multi precision
floating point (mpfr) and multi precision complex arithmetic (mpc). All those
old versions did not offer support for the AARCH64 architecture, which is a
requirement to make Genode self hosting. Targets for building binutils and GCC
within Genode for AARCH64 are in place, GNU make is in place, and even code
coverage (gcov) has been added. This work puts AARCH64 in line with other
supported CPU architectures and emphasizes our interest in the ARM 64-bit
architecture.
Platforms
#########
Execution on bare hardware (base-hw)
====================================
With the previous release, Genode's base-hw kernel got extended to support the
ARMv8-A architecture in principle. The first hardware supported was the
Raspberry Pi 3 as well as the i.MX8 evaluation kit (EVK). But only a single
CPU-core was usable at that time. Now, we lifted this limitation. On both
boards, all four CPU-cores are available henceforth.
Removed components
##################
The current release removes the following components:
:gems/src/app/launcher:
The graphical launcher remained unused for a few years now. It is not
suitable for systems as flexible as Sculpt OS.
:os/src/app/cli_monitor:
CLI monitor was a runtime environment with a custom command-line interface
to start and stop subsystems. It was part of the user interface of our
first take on a Genode-based desktop OS called
[https://genode.org/documentation/release-notes/15.11#Genode_as_desktop_OS - Turmvilla].
Nowadays, we use standard command-line tools like Vim to edit init
configurations dynamically, which is more flexible and - at the same time -
alleviates the need for a custom CLI. The CLI-monitor component was too
limited for use cases like Sculpt anyway.
Along with the CLI monitor, we removed the ancient (and untested for long
time) _terminal_mux.run_ script, which was the only remaining user of the CLI
monitor.
:fatfs_fs, rump_fs, and libc_fatfs plugin:
The stand-alone file-system servers fatfs_fs and rump_fs as well as the
fatfs libc plugin have been superseded by the fatfs and rump VFS plugins.
The stand-alone servers can be replaced by using the VFS server plus the
corresponding VFS plugin as a drop-in replacement.

Release notes for the Genode OS Framework 20.02
===============================================
Genode Labs
This year's [https://genode.org/about/road-map - road map] is all about making
Genode and Sculpt OS more approachable. It turns out that the first release of
the year already pays tribute to that goal. First, it equips Sculpt OS with a
much more logical and welcoming graphical user interface
(Section [Redesign of the administrative user interface of Sculpt OS]).
Second, it greatly reduces the friction when hosting existing applications on
Genode by smoothening several rough edges with respect to POSIX compatibility,
and by generally improving performance.
Most topics of the release are closely related to Sculpt. The biggest
break-though is certainly the ability of running Sculpt OS on 64-bit ARM
hardware (Section [Sculpt OS on 64-bit ARM i.MX8 hardware]) along with our
custom virtual machine monitor (VMM). On PC hardware, Sculpt users can enjoy
an updated audio driver and optimizations of the Seoul VMM. Furthermore,
Sculpt's window manager received the much anticipated ability to use virtual
desktops.
At the framework-API level, the most significant changes are the introduction
of dedicated types for inter-thread synchronization patterns
(Section [Base-framework refinements]) and a new library for
bringing the benefits of the Genode architecture to the application level
(Section [New sandbox library based on the init component]).
Redesign of the administrative user interface of Sculpt OS
##########################################################
On our [https://genode.org/about/road-map - road map] for 2020, we stated
the reducing of the barrier of entry as our main concern of the year.
We highlighted the ease of use of Sculpt OS as one particular work area.
Removing Unix from the picture
------------------------------
Until now, Sculpt's administrative user interface - lyrically called
Leitzentrale - employed a small Unix runtime and the Vim editor as utility for
basic file operations and for the tweaking of configurations. Even though this
was a practical intermediate solution, we have to face the fact that not
everyone loves the Unix command-line interface as much as we do. Quite the
opposite, actually. When presenting Sculpt, we can clearly sense that people
with a non-Unix background are put off by it. The audience generally loves the
runtime graph, visual cues, and discoverability. Furthermore, command-line
interfaces are (albeit wrongly) perceived as archaic and impenetrable relics
by many computer users who are otherwise perfectly happy with the notion of
files and directories. We identified that file-manipulation tasks performed in
the Leitzentrale are rare and simple. Relying on Unix for those basic tasks is
like taking a sledgehammer to crack a nut. On average, the Leitzentrale is
used in just a few moments a day for basic things like browsing a file-system
hierarchy, glimpsing at the reports stored on the report file system, deleting
or copying a file or two, or tweaking a configuration file. With a Unix shell
presenting one barrier, Vim is certainly an even higher one. Familiarity with
Vim should definitely not be a prerequisite for using an operating system.
Following this reasoning, we decided to swap out the command-line interface
and Vim by a simple GUI-based file browser and a notepad-like editor, which do
not require any learning curve.
Note that even once the Unix command-line interface is removed from Sculpt's
Leitzentrale, advanced users will still be able to manipulate Sculpt's config
file system via a Unix runtime deployed as a regular component, similar to the
use of the noux-system package we have today.
New user-interface layout
-------------------------
The move away from the command-line interface goes hand in hand with the
redesign of the overall user-interface layout. A new panel at the top of the
screen contains two centered tabs for switching between the runtime graph and
the file-system browser.
[image sculpt_20.02_panel]
The storage-management functionality has been moved from the former storage
dialog into the respective nodes of the runtime graph. E.g., to format a block
device, the user can now select a USB or storage node of the graph to get a
menu of block-device-level operations.
[image sculpt_20.02_storage]
The network-management is now located at a drop-down menu that can be toggled
via a button at the right side of the panel.
[image sculpt_20.02_network]
A new button on the left side of the panel allows the user to toggle a
drop-down menu for GUI settings. At the current time, there is only the option
to adjust the font size. In the future, the dialog will give easy access to
the screen-resolution options and the keyboard layout.
The log-message view is now hidden in another drop-down menu that can be
toggled via a panel button. So when starting the system, the user is greeted
with only the runtime graph, which is a much nicer and cleaner looking
experience.
Informative or diagnostic messages are displayed in the left-bottom corner of
the screen.
[image sculpt_20.02_message]
The "Files" tab of the panel switches the main screen area to a simple file
browser that lists all file systems available. By toggling one of the
file-system buttons, the directory hierarchy can be browsed. When hovering
a file, an "Edit" or "View" button appears, which can be used to open
the file in a text area that appears on the right side of the file browser.
The editor supports the usual notepad-like motions, operations, and
shortcuts (control-c for copy, control-v for paste, control-s for save).
[image sculpt_20.02_editor]
Half-way there
--------------
With the current release, one can already accomplish a lot without having to
resort to a command-line interface: connecting to the network, managing
storage devices, installing and deploying software, inspecting the system
state, and tweaking configurations.
There are still a few gaps though. In particular the file browser does
not yet support file operations like the copying, renaming, or removal of
files. For these tasks, the current version of Sculpt still features the
Unix-based inspect window, which can be accessed by toggling the "Inspect"
button inside the USB or storage dialog. Once selected, the panel presents an
"Inspect" tab that features the familiar Unix shell and Vim. Note, however,
that we keep the inspect window only as an interim solution. It will
eventually be removed. As with every new feature, there are still rough edges
to be expected in the editor and file browser, e.g., the editing of files with
long lines or the browsing of directories with many entries is not
appropriately covered yet.
To see the current new version of Sculpt OS in action, you may find the
following presentation entertaining.
:Live demonstration of Sculpt OS at FOSDEM 2020:
[https://fosdem.org/2020/schedule/event/uk_sculpt/]
The new version 20.02 of Sculpt OS is part of this release and can be built
from source and used right now. Several Genode developers already provide
ready-to-use packages for the new version. The software depots by alex-ab,
cnuke, skalk are worth exploring. A downloadable system image along with an
updated manual will be released shortly.
Sculpt OS on 64-bit ARM i.MX8 hardware
######################################
Within the past two releases, big steps were taken to support ARMv8 hardware in
the Genode OS framework. After implementing basic support for Raspberry Pi 3,
and the i.MX 8M Evaluation Kit, the network card was enabled for the latter.
Moreover, we updated the Linux TCP/IP, and C library ports, as well as
the Noux environment to support the architecture. Finally, with the latest
releases, a new ARMv8-compliant virtual-machine monitor for the base-hw kernel
entered the framework.
The rapid achievements motivated us to strive for a more ambitious scenario to
run on top of the currently focused ARMv8 hardware platform. So why not using
Sculpt OS on the i.MX 8M System-on-Chip?
Persistent storage
==================
There were several challenges to cope with initially. First, persistent
storage was needed. Luckily, the Genode OS framework contained already an
SD-card driver implementation for the i.MX series. The driver was written for
Genode from scratch and initially supported the i.MX53 SoC only. From then, it
got extended repeatedly to drive the SD-card controller of several i.MX6 and
i.MX7 platforms. Therefore, it was not a big issue to support the new hardware
too. However, when we later used it in Sculpt, it turned out that the driver
has some low-latency requirements. If those were not met, it got stuck. This
was the time where the CPU-quota mechanism came in handy in a real-world
scenario. It helped to let the interrupt handler of the driver be scheduled in
time, and thereby let the driver run stable.
Having a working block device is one part, but it is of little use without a
file system. In Sculpt OS, the NetBSD rump kernel's ext2 file-system is
typically used to host the depot package system and for keeping configuration
files persistent. Unfortunately, the version of NetBSD as used in Genode's
rump kernel port does not contain the ARMv8 architecture. Of course, we could
have upgraded the rump kernel as a whole. But this software stack is quite
complex with a lot of threads reproducing a sophisticated state machine. It
took some time in the past to meet its required semantics. Therefore,
backporting some header definitions and a few architecture-dependent functions
seemed more attractive. Luckily, it turned out to be the right decision, and
after a day of backporting work, the file system could run on ARMv8.
Display engine
==============
One of the more challenging tasks was certainly the enabling of the Display
Controller Subsystem (DCSS) of the i.MX 8M SoC. Originally, we hoped to profit
from our experiences with the Image Processing Unit (IPU), the display engine
of former i.MX SoCs. But as it turned out, the DCSS is a completely new
design, and has not much in common with the IPU. When first writing a driver
for the IPU of the i.MX53, we were surprised by the complexity and flexibility
of this piece of hardware. Back then, it took months to get something
meaningful working. To not lose too much time by re-implementing a driver from
scratch, we decided to take the DDE Linux approach, which worked out pretty
fast. The resulting driver should provide the same flexibility like the Linux
original one. However, as the i.MX 8M EVK board provides a HDMI connector
only, we did not test more than that. The configuration of the driver is
analogous to the Intel framebuffer driver, and looks like the following:
! <config>
! <connector name="HDMI-A-1" width="1920" height="1080" hz="60" enabled="true"/>
! </config>
Later, when using the driver in practice within the Sculpt OS, we could
experience a slightly sluggish behaviour, which was due to a missing
architectural back end of the blitting library of Genode. After tweaking this
too, the graphical user interface experience was good.
USB and Input
=============
The last missing I/O device to run Sculpt OS on the ARMv8 was something for
user generated input. Therefore, the existent USB host controller driver for
the i.MX series got updated. The only roadblock here was the powering of the
device. As there is no platform driver for the target hardware yet, which
would manage power and clocks, the hardware either has to be pre-configured
correctly, or the driver has to enable it on its own. Ethernet card, SD-card,
and the display engine were all already powered by the bootloader, but not
USB. In contrast to the first devices, the u-boot bootloader turns off USB
explicitly as soon as it starts the OS. As an interim solution, we patched
u-boot to not turn off the USB host controller, and enforced u-boot to
initialize the powering in our boot scripts. Therefore, if one wants to use
USB on the i.MX 8M EVK, make sure to take our modified version. As a
convenient solution, you can use the 'uboot' port within the base repository.
Just issue the following command in the Genode directory:
! tool/ports/prepare_port uboot
Finally, you have to copy u-boot to the SD-card as root user:
! dd if=`tool/ports/current uboot`/imx8q_evk/imx-mkimage/iMX8M/flash.bin \
! of=/dev/sd<?> bs=1k seek=33 conv=fsync
Of course, you have to replace 'sd<?>' with the correct device node of your
attached SD-card.
After enabling the USB host controller driver, we could successfully re-use the
USB HID client driver to drive keyboard and mouse connected to the board. As a
nice side-effect, the list of possible storage devices got extended with USB
mass storage too by adding the USB block client driver.
Missing libraries
=================
Finally, when building the necessary and optional packages for Sculpt OS, we
stumbled across several libraries that needed to be adapted to compile and
link for ARMv8 too. Mostly, the inclusion of some other compilation units and
headers was sufficient. The related libraries are: libssl, libcrypto, libpng,
and Mesa. With the latter two, it is now even possible to execute Qt5
components on the target hardware.
Apart from all the new driver components and extended libraries, the Sculpt
manager had to be slightly modified to execute on the i.MX 8M hardware. In its
original form it is inherently dependent on x86 drivers, as it for example
generates configurations for some of those drivers. For the time being, the
changes to the Sculpt manager are not yet part of the official release.
Nevertheless, you can produce a Sculpt OS image to be run on an i.MX 8M EVK
board by using the following
[https://github.com/skalk/sculpt_20.02_imx8q_evk/ - topic branch].
Alternatively, you can also have a look at Sculpt OS on ARMv8 hardware by
following the video recordings of the following talk at FOSDEM 2020.
:Live demonstration of Sculpt OS on i.MX 8M EVK at FOSDEM 2020:
[https://fosdem.org/2020/schedule/event/uk_genode_armv8/]
Base framework and OS-level infrastructure
##########################################
New sandbox library based on the init component
===============================================
The init component is Genode's canonical mechanism for the composition of
components. This role was further amplified when init became
[https://genode.org/documentation/release-notes/17.02#Dynamically_reconfigurable_init_component - dynamically reconfigurable].
The latter change cleared the ground for system scenarios like Sculpt OS, the
on-target deployment of packages, and dynamic device discovery. One typical
pattern found in such scenarios is one dynamically configured instance of init
accompanied by a controlling component that is usually called "manager". The
manager would consume reports of the subsystem hosted within the dynamic init,
and adjust the init configuration according to a domain-specific policy. Such
a configuration change, in turn, may trigger new reports, which effectively
turns this setting into a feedback control loop.
Whereas this established pattern is suitable for many scenarios, it is not
always natural. In particular if the manager does not only need to
manage a subsystem but also wants to intercept a service used by the
subsystem, the roles are no longer clear-cut. A practical example is a
GUI application that employs the menu-view component for the GUI rendering
while processing keyboard events locally. This application would need to
intercept the menu-view's GUI session to obtain the stream of user input
events. For such an application, the most natural approach would be the
co-location of the init functionality with the application logic into a
single all-encompassing component.
To accommodate such scenarios where a domain-specific management component is
tightly coupled with a dynamic subsystem, we extracted the child-management
functionality from the init component into a new library called "sandbox". The
library API is located at
[https://github.com/genodelabs/genode/blob/master/repos/os/include/os/sandbox.h - os/include/os/sandbox.h].
In addition to the hosting of components, the sandbox API also allows for the
interaction with the sandboxed children by providing locally implemented
services. The latter mechanism is illustrated by a new test available at
_os/src/test/sandbox_.
POSIX compatibility improvements
================================
During the release cycle of Genode 20.02, we continued our mission to host
POSIX software effortlessly as Genode components. In particular, we followed
up the line of work pursued with the two previous releases
[https://genode.org/documentation/release-notes/19.08#Consolidation_of_the_C_runtime_and_Noux - 19.08] and
[https://genode.org/documentation/release-notes/19.11#C_runtime_with_improved_POSIX_compatibility - 19.11]
with respect to the traditional Unix mechanisms fork, execve, and pipes.
After covering several edge cases - cloexec, file-descriptor lifetimes,
line-buffer handling, vfork, just to name a few - as needed by programs like
make, bash, and tclsh, we eventually reached a state where the website
generator of [https://genodians.org] works without the need for the now
deprecated Noux runtime.
For years we have been running complex software stacks like the Qt-based web
browser on top of our C runtime but not without carefully placed tweaks and
occasional patches. With the current release, we address the area of
concurrency and introduce a thorough reimplementation of the synchronization
primitives namely POSIX mutexes and condition variables as well as semaphores.
We also reaped the fruit of our labor by replacing our custom Qt thread back
end by the standard POSIX-thread based implementation. Further, we reduced the
number of threads in Qt applications by moving the QPA event handling to the
component entrypoint and removing the timed-semaphore utility from LibC.
Beyond Qt, we also address synchronization issues revealed by running a
third-party port of [https://grpc.io/ - gRPC] in our network back ends and
amended thread-local errno in the C runtime. Finally, our POSIX thread
implementation supports cleanup handlers now.
Base-framework refinements
==========================
Replacing the 'Lock' type by new 'Mutex' and 'Blockade' types
-------------------------------------------------------------
Up to now, Genode's lock implementation supports mainly two flavours of usage.
On the one hand, it is used to protect critical sections where the lock is
initialized as unlocked. In the contention case, the lock holder is supposed
to release the critical section. On the other hand, the lock is used as
blockade to synchronize startup between various executions of threads. Here
the lock is initialized as locked during instantiation whereby the thread that
releases the lock is not necessarily the same thread as the creator of the
lock.
We decided to make the two usage patterns more obvious by introducing two
separate classes, called 'Mutex' and 'Blockade'. The reasons are twofold.
First, during code review, the usage pattern at hand becomes more obvious.
Second, by codifying the programmer's intent behind the use of a
synchronization primitive, Genode becomes able to perform additional checks,
and diagnose certain dead-lock situations and other usage errors on the spot.
The separation got introduced shortly before this release. Up to now, it is
only used in 'Genode::Thread', 'Genode::Heap', and 'Genode::Registry'. The
plan is to cultivate the usage across all Genode sources over the next
releases and to ultimately remove the 'Genode::Lock' from the public API.
The 'Mutex' class is more restrictive compared to the 'Lock' class.
* At initialization time, it is always unlocked.
* To enter and leave a critical section the methods 'acquire()' and
'release()' are used.
* A 'Mutex::Guard' is provided, which will 'acquire()' a mutex at
construction time and release it automatically at destruction time of
the guard.
* No thread is permitted to lock twice. The code will generate a warning if
a dead-lock is detected.
* Only the lock holder is permitted to release the mutex. The code will
generate a warning and will not release the mutex if this rule is violated.
! Genode::Mutex mutex;
! mutex.acquire();
! mutex.release();
!
! {
! Genode::Mutex::Guard guard(mutex) /* acquire() during construction */
! } /* release() on guard object destruction */
!
! Genode::Mutex::Guard guard(mutex);
! mutex.acquire(); /* <-- Will cause a warning about the dead-lock */
The 'Blockade' class is always initialized as locked and provides the methods
'block()' and 'wakeup()'. Beside the initialization aspect, the 'Blockade'
behaves up to now like the 'Genode::Lock' implementation.
! Genode::Blockade blockade;
!
! /* step */ /* thread A */ /* thread B */
! 0: -start thread B-
! 1: ... -startup-
! 2: blockade.block(); ...
! 3: -sleep- ...
! 4: -sleep- blockade.wakeup();
! 5: ... ...
Performance optimization of the XML parser
------------------------------------------
Genode's XML parser used to rely on C++ exceptions while parsing, which is an
almost historic artifact inherited from the initial implementation. The
performance penalties of exceptions in the rare use of XML was acceptable
back when we started. But modern Genode systems like Sculpt OS rely on the
dynamic processing of XML like a back bone. The overhead became particularly
apparent when executing [Sculpt OS on 64-bit ARM i.MX8 hardware]. Prompted by
this observation, we reworked the code such that exceptions are no longer
thrown in any hot code path. The public interface of 'Xml_node' remains
unchanged.
New polling variant for register framework
------------------------------------------
Genode's register framework has offered a 'wait_for' method for a long time.
This function sleeps for a certain amount of microseconds and checks if one or
more given conditions become true. The number of attempts to sleep and check
the conditions must also be specified. In case the conditions are not met
after these attempts, a polling timeout exception is thrown. The function
simply returns in case of success. With the current Genode release, we have
added a 'wait_for_any' method with almost the same semantics but instead of
waiting for all conditions to become true, it returns if any condition is
met, and thus, implements a logical OR.
Migration to modern block-device API
====================================
With release 19.02, Genode introduced two new APIs for block-session handling.
The client side of a block session now uses the job API in order to send block
requests to the server, which in turn receives those jobs as requests through
the Request API. These two APIs replace Genode's 'Block::Driver' and
'Block::Session_component' implementations that used the packet stream API
directly, which turned out to be error prone for block session implementations.
Instead, these new APIs wrap the packet stream handling in a controlled
manner while handling all corner cases and even the overcommit of packets.
With the current release, we have adapted Genode's AHCI driver and partition
manager to these new interfaces, with the plan to adjust all block session
clients/servers to the new APIs with Genode release 20.05.
During this line of work, the AHCI driver received a major cleanup. For
example, dynamic memory allocations were removed, the whole initialization
state machine has been removed, ATAPI support for Qemu has been re-enabled,
and Exynos5 AHCI support is gone - since the platform is outdated and not
supported by Genode any more.
Updated audio driver based on OpenBSD 6.6
=========================================
In this release, we updated the 3rd-party sources of the audio driver component
to OpenBSD 6.6 and adapted the emulation glue code. While doing so, we fixed
a bug regarding the 'delay()' implementation where the function expects
microseconds but was given milliseconds. This led to a increased start-up
time of the component. We also fixed the logging back end that accidentally
was rendered silent and brought in the 'printf' back end from DDE Linux to
be able to produce better formatted LOG messages in the future.
Until now the component only supported HDA and EAP (ES1370 PCI) devices. The
first is primarily intended to be used with real hardware whereas the latter
was used during the initial porting effort in Qemu. That being said, the EAP
driver apparently also works on hardware according to community feedback.
Since the HDA driver does not work when used in VirtualBox and users expressed
the desire to also use audio when running in a VM, we enabled another driver,
for which a device-model in VirtualBox exists: the AC97 ICH. As it turned out,
using this driver, we can produce audio, albeit the quality is far from
usable. Nevertheless, with the driver enabled, interested parties are free to
investigate the cause for the current issues.
All in all, this update is solely a catch up effort to stay more
up-to-date with the upstream changes and to pull in HDA quirks for more
recent systems. More interesting changes to the driver component, like
reworking the OpenBSD kernel emulation layer and bringing support for USB
audio devices, are scheduled for future releases.
Support for unlabeled LOG output
================================
In situations where a Genode system is remotely controlled and monitored,
it is useful to allow a special component to produce log output with no
Genode label applied. This way, such a component can produce log data in
a format that is immediately suitable for a controller. This feature can be
enabled for a component by rewriting the label of the component's LOG session
to "unlabeled".
! <route>
! <service name="LOG"> <parent label="unlabeled"/> </service>
! ...
! </route>
Libraries and applications
##########################
Custom virtual machine monitor on ARM
=====================================
The ARMv8-compliant virtual-machine monitor introduced in the previous release
19.11 now contains new device models to enable the interaction with a
virtual-machine via network and terminal services. The new virtual ethernet
card and console implementations are compliant to the virtualization standard
VIRTIO 1.1.
Currently, the VMM cannot be configured to contain specific devices. It is
hard-wired to provide exactly:
* One virtual ethernet card that connects to Genode's "Nic" service,
* A VIRTIO console that opens up a session to the "Terminal" service using the
label "console", and
* The traditional PL011 serial device model, which connects to a
"Terminal" service too but uses the label "earlycon"
Seoul VMM
=========
During the usage of Seoul on Sculpt, it became apparent that the Seoul VMM
caused a constant CPU load even when the guest VM was idling. After some
investigation it became clear that having a fixed rate to synchronize the
guest graphic memory with the Genode GUI service was the main reason for the
constant load. With this release, we added the feature to dynamically adjust
the GUI refresh rate depending on the rate of user interactivity.
Additionally, if all virtual CPUs go to idle state, the GUI refresh is stopped
completely. With these measures, the overall CPU load could be reduced
noticeably.
TCP terminal
============
The TCP terminal is a long-living component in the Genode OS framework since
release 11.11. It can be used, e.g., to connect to a headless Genode system
via telnet. Until now, it always listened to incoming network connections at
configured ports. The port had to be configured for each terminal session
client.
The TCP terminal got extended to either listen to incoming network
connections, or to directly connect to another network server, dependent on
the policy defined for the corresponding terminal client. The following
example configuration illustrates the differences:
! <config>
! <policy label="client" ip="10.0.0.5" port="1234"/>
! <policy label="another_client" port="4567"/>
! </config>
If only a port is described in the policy, the TCP terminal will listen on
that port for incoming connections. If an IP address is provided additionally,
it connects to the IP address using the given port.
Virtual desktops
================
Genode's GUI stack enables a high degree of flexibility. Beside the fundamental
nitpicker component, responsible for basically multiplexing input events and
framebuffer content, there is the window-manager component, and example
implementations of a window-layouter, and decorator. The interplay of the
latter three allows a window management that scales from simple to rich and
sophisticated without lowering its security properties. For a brief description
of its architecture, please refer to the release notes of
[http://genode.org/documentation/release-notes/14.08 - 14.08].
In this architecture, the window layouter is responsible for the arrangement
of the different windows. It exports a data model of the window layout.
Although, the example implementation of the window layouter introduced in
14.08 was simple, it already contained a notion of having different virtual
screens and screen sections, beside the actual window placements. However,
until now there was no use-case of switching dynamically between different
virtual screens respectively window sets related to them.
While using more and more different graphical components within Sculpt, the
window layouter in its initial form hit a limit. Although it already allowed to
switch in-between different windows via configured key-combinations, it became
inconvenient when having more than a handful windows hiding each other.
Therefore, the window layouter now got extended to allow switching dynamically
in between several pre-defined virtual screens. For the time being, one has to
assign a new window to a screen in the rule-set of the window layouter
initially by hand. Defining the currently visible screen can either be done by
editing the rule-set, or by using pre-configured key-combinations.
The new default configuration of the window layouter as exported by its
corresponding depot package looks like the following:
! <config rules="rom">
! <rules>
! <screen name="screen_1"/>
! <screen name="screen_2"/>
! <screen name="screen_3"/>
! <screen name="screen_4"/>
! <screen name="screen_5"/>
! <screen name="screen_6"/>
! <screen name="screen_7"/>
! <screen name="screen_8"/>
! <screen name="screen_9"/>
! <screen name="screen_0"/>
! <assign label_prefix="" target="screen_1" xpos="any" ypos="any"/>
! </rules>
!
! <press key="KEY_SCREEN">
! <press key="KEY_ENTER" action="toggle_fullscreen"/>
! <press key="KEY_1" action="screen" target="screen_1"/>
! <press key="KEY_2" action="screen" target="screen_2"/>
! <press key="KEY_3" action="screen" target="screen_3"/>
! <press key="KEY_4" action="screen" target="screen_4"/>
! <press key="KEY_5" action="screen" target="screen_5"/>
! <press key="KEY_6" action="screen" target="screen_6"/>
! <press key="KEY_7" action="screen" target="screen_7"/>
! <press key="KEY_8" action="screen" target="screen_8"/>
! <press key="KEY_9" action="screen" target="screen_9"/>
! <press key="KEY_0" action="screen" target="screen_0"/>
! ...
As can be seen, individual keys are assigned to switch to a specific virtual
screen. By default ten screens are defined that are accessible via the number
keys. The first screen definition in the rules configuration marks the
currently visible screen.
Menu-view widget renderer
=========================
The line of work described in Section
[Redesign of the administrative user interface of Sculpt OS] called for
the enhancement of Genode's GUI-rendering component. This component - named
menu view - was
[https://genode.org/documentation/release-notes/14.11#New_menu_view_application - originally introduced in Genode 14.11]
for the rendering of the relatively simple menus of an application launcher.
Its software design largely deviates from the beaten track of established
widget toolkits, which come in the form of client-side libraries. The
menu view is not a complete toolkit but solely a dialog renderer sandboxed
in a dedicated component. This design reinforces the strict separation of the
view from the application logic, fosters screen-resolution independence, and -
most importantly - keeps the complexity of pixel processing out of the
application program. Because of the latter, it lends itself to the
implementation of security-sensitive interactive applications.
It would certainly be misguiding to tout our menu-view as feature competitive
with existing toolkits. We certainly won't recommend using it over Qt in
general. But Sculpt's custom administrative user interface "Leitzentrale"
presented us with the perfect playground to explore and grow the potential of
our novel approach.
In contrast to the previous iteration of the Leitzentrale GUI, which relied on
a small Unix runtime and Vim for editing text files, the new version ought to
feature a simple text editor integrated in the GUI. A text editor requires
a much tighter interplay between the view and the actual program logic
compared to an application with just a bunch of buttons. Think about cursor
handling, scrolling text, displaying textual selections, or placing a text
cursor with the mouse. On the course of the work towards the text-area
component featured in the new Leitzentrale, the menu view received the
following improvements:
:Text-cursor support:
The label widget gained the ability to display one or multiple text cursors,
as illustrated by the following example:
! <label text="...">
! <cursor at="10"/>
! </label>
For the display of multiple cursors, each cursor must feature a distinctive
'name' attribute.
:Character position featured in the hover report:
The hovering information provided by the menu view used to be at the
granularity of widgets, which is insufficient for placing a text cursor with
the mouse. Hence, the information of a hovered label additionally provides
the character position within the label now.
:Unquoting label text attribute values:
The text displayed in label widgets is provided by a 'text' attribute value,
which raises the question of how to present '"' characters on the GUI. With
the new version, the attribute value can contain XML-quoted characters,
specifically "&quot;".
:Support for displaying text selections:
Similarly to the way of how a <cursor> can be defined for a <label>
widget, a selection can now be expressed as follows:
! <label ...>
! <selection at="2" length="12"/>
! </label>
:Support of multiple '<float>' widgets within a '<frame>':
We refined the hover reporting of <float> widgets such that a float widget
never responds to hovering unless a child is hovered. This way, it becomes
possible to stack multiple float widgets within one frame and still reach
all child widgets. This is useful for aligning multiple widgets within one
screen area independently from each other. For example, for left-aligning,
centering, and right-aligning the elements of a panel.
:Enforcing the minimum size of a label:
The new '<label min_ex="..">' attribute can be used to enforce a minimum
width in the unit of the size of the character 'x'. In the absence of a
'text' attribute, the minimum height of a label is implicitly set to 0. The
combination of both changes makes the label usable as a horizontal spacer.
:Basic support for styling labels:
The new version allows for the customization of the text color and alpha
value of the label widget by the means of a style-definition file. The
mechanism is exemplified with the new "invisible" label style that sets the
alpha value to zero.
With these few incremental changes in place, the menu-view widget renderer
becomes usable as the basis of the simple text editor used in Sculpt's new user
interface.
Self-hosting the tool chain on 64-bit ARM
=========================================
With our ongoing ARM 64-bit effort, we have successfully updated Genode's tool
chain with release
[https://genode.org/documentation/release-notes/19.05#Broadened_CPU_architecture_support_and_updated_tool_chain - 19.05].
With the current release, we have additionally managed to make Genode's tool
chain self hosting on ARM 64-bit, which means the tool chain can compile
source code on ARM 64-bit directly.
Platforms
#########
Execution on bare hardware (base-hw)
====================================
The generic code base of the base-hw kernel underwent several cosmetic changes
to reduce or eliminate the application of certain problematic constructs like
too much inheritance, pointers, and dynamic casts. Those changes were
motivated to ease the translation of several kernel parts to the Ada/SPARK
language in the context of the Spunky project. For more information regarding
this experiment to write a Genode kernel in Ada/SPARK, please have a look at
the recent [https://genodians.org/m-stein/index - genodians.org article series]
of Martin Stein or listen to his recent
[https://video.fosdem.org/2020/AW1.125/ada_spunky.mp4 - FOSDEM talk].
Moreover, the IPC path implementation got simplified to lower the overhead
costs introduced by the transfer of capabilities. Together with the mentioned
Spunky cleanup efforts, this change measurably improved IPC performance.
The base-hw kernel now exports time consumption of individual threads via
the trace service analogously to the implementation for NOVA. Thereby, it
becomes possible to use for instance the top component within the Sculpt OS
also on this kernel.
Until now, support for the Raspberry Pi 3 was limited to Qemu emulation only.
Thanks to a contribution of Tomasz Gajewski, it is now possible to execute
Genode on all four CPUs of the actual hardware concurrently.
Execution on Linux
==================
Traditionally, the Linux version of Genode serves us as very handy development
vehicle but it was never intended as an actual target platform. On Linux,
Genode is usually executed as a multi-process application on top of a regular
GNU/Linux desktop distribution by specifying 'KERNEL=linux' and 'BOARD=linux'
to the run tool.
However, thanks to the work of Johannes Kliemann, Genode has become able to
run on a bare-bone Linux kernel without any other user land.
We blatantly used to refer to this idea as the
[https://genode.org/about/challenges#Platforms - microkernelization of Linux].
Johannes picked up the idea, supplemented Genode's core with the services
needed for user-level device drivers (IRQ, IOMEM, IOPORT) and supplemented
the tooling for the integration of Genode scenarios into a bootable initrd
image. This target of execution can be addressed by specifying 'KERNEL=linux'
and 'BOARD=pc' to the run tool now. If specified, the run tool will produce a
bootable Linux system image for the given run script and run it in Qemu.
That said, as this line of work is still considered as an experimental
playground - not for productive use - the work flow is not entirely automated.
In particular, one needs to prepare a suitable
[https://github.com/jklmnn/linux/commits/genode - Linux kernel] manually.
If you are interested in the topic, please refer to the background information
given in the [https://github.com/genodelabs/genode/pull/2829 - issue tracker].

Genode technology to a certain direction, we are willing to revisit our plans.
Review of 2017
Review of 2019
##############
The technical topics of 2017 ranged from hardware-accelerated graphics, over
UEFI, greatly improved seL4 support, user-level networking, file-system
infrastructure, to an consolidated framework API. However, one topic stood out
the most, which is the practical use of Genode as day-to-day OS.
For the road map 2019, we picked "bridging worlds" as our guiding theme:
(1) Lowering the friction when combining existing software with Genode,
(2) Fostering interoperability with widely used protocols and APIs, and
(3) Making Genode easier to approach and generally more practical.
Whereas the so-called "Turmvilla" system scenario enabled a few enthusiasts to
work on a Genode-based system since mid of 2015, the scenario was quite rigid
and required significant manual labour for any customization. Although it was
not really inviting for potential users, it illustrated well that all the
basic building blocks - in particular the driver stacks - were in place. But
it would have been be quite a stretch to call Turmvilla a general-purpose OS
at that point. The year 2017 introduced two pivotal features that allowed us to
break free from the limitations of Turmvilla-like scenarios, namely the new
[https://genode.org/documentation/release-notes/17.05#Package_management - package-management concept]
and the ability to
[https://genode.org/documentation/release-notes/17.02#Dynamically_reconfigurable_init_component - compose and modify subsystems dynamically].
With respect to (1), we identified Genode's custom tooling (build
system, run scripts, ports mechanism, depot tools) as a point of
friction. They are arguably powerful and flexible but require a lot of
up-front learning. This is certainly a burden unacceptable for a casual
developer without a black belt in Make and Expect/Tcl. The new
[https://genode.org/documentation/release-notes/19.11#New_tooling_for_bridging_existing_build_systems_with_Genode - Goa]
tool rearranges the existing tools in a way that puts the concerns of casual
developers into focus, allowing for the use of commodity build systems,
eliminating Tcl syntax from the equation, running sub-second test cycles, and
streamlining the packaging of software.
Inspired by these new features, a new system scenario called "Sculpt" emerged
in Autumn 2017. The combination of Genode's recursive architecture with the
dynamic reconfigurability of the init component allows the user to
interactively shape the running Genode system including any subsystem or even
configurations of individual components. The system structure is always at the
user's fingertips and can by modified instantly using a text editor. At the
same time, the new package management greatly helps to keep the complexity at
a manageable level. Whereas Turmvilla users rarely updated their installation
out of hesitance to break their work environment, Sculpt is routinely updated
on a weekly basis. The switch of the entire Genode-Labs team to Genode full
time by the end of year was certainly our biggest milestone so far.
On account of (2), we
[https://genode.org/documentation/release-notes/19.05#Broadened_CPU_architecture_support_and_updated_tool_chain - switched to C++17]
by default, fostered the use of
[https://genodians.org/ssumpf/2019-02-27-java-19-02 - Java],
updated Qt5, and put
[https://genode.org/documentation/release-notes/19.11#C_runtime_with_improved_POSIX_compatibility - POSIX]
compatibility into the spotlight. We were eventually able to dissolve the need
for our custom Unix runtime (Noux) because all features of Noux are covered by
our regular libc now.
Our biggest step towards (3) is the [https://genodians.org] website we
started in winter 2019, which gives individual members of our community
an easy way to present thoughts, projects, and experiences.
Complementing Genode's formal documentation, it also conserves practical
tips and tricks that were previously not covered in written form.
When speaking of "bridging worlds", we should not forget to mention the
tremendous effort to bring Sculpt-OS-like workloads to the 64-bit ARM world.
Thanks to the added support for
[https://genode.org/documentation/release-notes/19.08#64-bit_ARM_and_NXP_i.MX8 - multi-core AARCH64],
hardware-based
[https://genode.org/documentation/release-notes/19.11#Virtualization_of_64-bit_ARM_platforms - virtualization],
and network/USB/graphics drivers for the i.MX8 SoC, the flexibility of Sculpt
OS will eventually become available on PC hardware and ARM-based devices
alike.
Over the course of 2019, we admittedly skipped a few topics originally
mentioned on our road map. In particular, the user-visible side of
Sculpt OS received less attention than originally envisioned. We also
deferred several ideas we had in mind about reworking our GUI stack.
Instead, we expanded our work in the areas of storage (block-level APIs,
test infrastructure,
[https://genode.org/documentation/release-notes/19.11#Preliminary_block-device_encrypter - block encryption])
and
[https://genode.org/documentation/release-notes/19.08#Flexible_keyboard_layouts - input processing].
This shift of focus is mostly attributed to the priorities of Genode Labs'
customers who fund our work.
2018 - The year of Sculpt
#########################
2020 - Dwarfing the barrier of entry
####################################
The "Turmvilla" era lies behind us. So let the "Sculpt" era begin!
Genode as a technology is there. For more than one decade, we walked unfathomed
territory, fought with countless deep rabbit holes, took risky decisions,
tracked back, explored design spaces, developed taste and distaste, pruned
technical debt, and eventually found formulas of success. Today, there are no
(fundamental) unsolved questions. All the puzzle pieces are in place. There
could be no better proof than our daily use of Sculpt OS. The time is right
to make Genode palatable for a wider circle. We identified four actionable
topics to achieve that.
Having used Sculpt over the past few months, we feel confident to make the
system scenario available to a larger audience. In 2018, we will take four
steps:
:User friendliness of Sculpt OS:
# Sculpt for Early Adopters (EA)
Until now, Sculpt OS is not exactly friendly towards users who are
unfamiliar with the Unix command-line tools. Since Sculpt is not Unix
based, this is a bit paradoxical. 2020 will give Sculpt OS a friendlier
and discoverable user experience. In this context, we will inevitably
put our attention to Genode's GUI stack.
The current version of Sculpt accompanied with plain-text documentation
that explains the concept and use. It is intended for people who are
already familiar with Genode, in particular users that experimented with
Turmvilla-like scenarios in the past. Sculpt EA expects basic Vim skills
from the user.
:Perception of high quality:
# Sculpt for The Curious (TC)
Compared to commodity operating systems who stood the test of time,
Genode is a young and largely unproven technology. It understandably calls
for skepticism. All the more we must leave no doubts about our high
quality standards. There must be no room for uncertainty. Hence, during
2020, we will intensify the consolidation and optimization of the framework
and its API, and talk about it.
A polished version of Sculpt that is more welcoming to the user and
accompanied with example subsystems that loosely resemble a traditional
notion of an operating system (like basic menus and window borders).
There will be a ready-to-use ISO image for Sculpt TC. So users won't need
to be familiar with Genode's source code and build system. As with Sculpt
EA, Sculpt TC will still rely on the user's ability to use Vim.
:Enjoyable tooling:
# Sculpt by Visual Composition (VC)
Genode's success at large will depend on developers. As of today, software
development for Genode requires a huge up-front learning curve. This is
fine for people who are already convinced of Genode. But it unacceptable
for casual developers who want to get their toes wet. We should aim for
tooling that allows new developers to keep up their flow and beloved
tools. The recently introduced [https://genodians.org/nfeske/2019-11-25-goa - Goa]
tooling is our first take in this respect. It is certainly too early to call
Goa a success. In order to find out if we are on the right track, we want to
expose Goa to as many problems as possible, primarily by the means of
porting software. Also, things like IDE usage or adapters for a variety of
build systems will certainly move into focus in 2020.
Whereas the earlier versions rely on text editing for sculpting the system,
Sculpt VC will feature an interactive graphical user interface, which will
hopefully make the system tangible for users who live outside the terminal.
:Convincing use cases:
# Sculpt as a Community Experience (CE)
Sculpt CE will allow anyone to play the role of a component provider.
Each user should be able to pick individual components or entire component
compositions provided by others while maintaining complete control over the
system.
In addition to working on Sculpt as the overall theme of the year, we will
focus on the following topics:
:Gentle transition from NOVA to our custom kernel and seL4:
NOVA used to be our kernel of choice on x86 platforms. However, since the
kernel is no longer actively developed, we had to take over the
responsibility to maintain it. Whereas we feel confident in developing the
kernel in an evolutionary way, the kernel has long-standing architectural
limitations (i.e. kernel-memory management) that would require invasive
changes. Instead of ramping up our engagement with NOVA, we'd like to focus
on our custom kernel (base-hw) and the seL4 kernel. In 2018, we set out to
enable Sculpt on base-hw. This involves the support for SMP, VT-x, and VT-d
on x86.
:Freescale i.MX:
Based on the feedback from our community, Freescale i.MX support is of
great interest, specifically i.MX6. Hence, we plan to improve the driver
support for this SoC.
:seL4:
We will try to apply all improvements of Genode on seL4 whenever feasible.
It also goes without saying that we will track seL4's upstream development.
:Software quality and resilience:
The modernized framework API introduced last year is an important stepping
stone. But there is much more we can (and should) do, I.e., learning from
the high-integrity computing community (e.g., implementing critical
components in SPARK), leveling-up the scope and intensity of our automated
tests, facilitating static code analysis, and employing software-hardening
techniques. Of course, this scope goes far beyond the time frame of one
year. The immediate prioritization of these topics will largely depend on
the focus of commercial users funding the work.
:System monitoring, tracing, profiling:
The interactive use of Sculpt along with the prospects enabled by Genode's
GPU support motivate us to optimize Genode towards low-latency multimedia
applications. We will ultimately need to gain a deep understanding on
inter-component interactions, in particular along time-critical data paths.
Therefore, we plan to improve the tooling and cultivate the use of our
existing but underused tracing support.
:Java:
By the end of 2018, we want to enable Genode to leverage the ecosystem
around Java, which is - according to the TIOBE index - the most popular
programming language.
Use cases can give exemplary proof of the fitness of Genode. We already
took a few baby steps to extend the range of documented use cases beyond
Sculpt OS last year. The boot2java scenenario comes in mind. 2020 will
hopefully see several more illustrations of Genode's versatility.
Milestones for 2018
Apart from this overall theme, we plan to continue our commitment to the
NXP i.MX SoC family, revisit Genode's low-latency audio support, and
extend the cultivation of Ada/SPARK within (and on top of) Genode.
Milestones for 2020

Background information - Why do we need a special tool chain?
#############################################################
Early on in the genesis of Genode, we introduced a custom tool chain to
overcome several problems inherent to the use of standard tool chains installed
on Linux host platforms.
First, GCC and binutils versions vary a lot between different Linux systems.
Testing the Genode code with all those different tool chains and constantly
adapting the code to the peculiarities of certain tool-chain versions is
infeasible and annoying. Second, Linux tool chains use certain features that
stand in the way when building low-level system components. For example, the
'-fstack-protector' option is enabled by default on some Linux distributions.
Hence, we have to turn it off when building Genode. However, some tool chains
lack this option. So the attempt to turn it off produces an error. The most
important problem with Linux tool chains is the dependency of their respective
GCC support libraries on the glibc. When not using a Linux glibc, as the case
with Genode, this leads to manifold problems, most of them subtle and extremely
hard to debug. For example, the support libraries expect the Linux way of
implementing thread-local storage (using segment registers on x86_32). This
code will simply crash on other kernels. Another example is the use of certain
C-library functions, which are not available on Genode. Hence, Genode provides
custom implementations of those functions (in the 'cxx' library).
Unfortunately, the set of functions used varies across tool-chain versions. For
these reasons, we introduced a custom configured tool chain where we mitigated
those problems by pinning the tools to certain versions and tweaking the
compiler configuration to our needs (i.e., preventing the use of Linux TLS).
That said, the use a our custom configured tool chain was not free from
problems either. In particular, the script for creating the tool chain relied
on a libc being present on the host system. The header files of the libc would
be used to build the GCC support libraries. This introduced two problems. When
adding Genode's libc to the picture, which is based on FreeBSD's C library, the
expectations of the GCC support libraries did not match 100% with the semantics
implemented by Genode's libc (e.g., the handling of 'errno' differs). The
second problem is the limitation that the tool chain could only be built for
the platform that corresponds to the host. For example, on a Linux-x86_32
system, it was not possible to build a x86_64 or ARM tool chain. For this
reason we used the ARM tool chains provided by CodeSourcery.
With Genode 11.11, we addressed the root of the tool-chain problem by
completely decoupling the Genode tool chain from the host system that is used
to build it. The most important step was the removal of GCC's dependency on
a C library, which is normally needed to build the GCC support libraries. We
were able to remove the libc dependency by sneaking-in a small custom libc stub
into the GCC build process. This stub comes in the form of the single header
file 'tool/libgcc_libc_stub.h' and brings along all type definitions and
function declarations expected by the support-library code. Furthermore, we
removed all GNU-specific heuristics from the tool chain. Technically, the
Genode tool chain is a bare-metal tool chain. But in contrast to existing
bare-metal tool chains, C++ is fully supported.
With the libc dependency out of the way, we are now free to build the tool
chain for arbitrary architectures, which brings us two immediate benefits. We
do no longer have to rely on the CodeSourcery tool chain for ARM. There is now
a 'genode-arm' tool chain using the same compiler configuration as used on x86.
The second benefit is the use of multiarch libs on the x86 platform. The
genode-x86 tool chain can be used for both x86_32 and x86_64 as build target,
the latter being the default.
Since we introduced GDB support into Genode, we added GDB in addition to GCC
and binutils to the Genode tool chain. The version is supposed to match the one
expected by Genode's GDB facility, avoiding potential problems with mismatching
protocols between GDB monitor and GDB.

Subject: [PATCH 02/15] FOC: change l4_task_cap_equal semantic
The syscall l4_task_cap_equal almost returns false although the referenced
kernel-objects are equal. This patch changes the semantic of the syscall so that
whenever two capabilities refering the same kernel-object are compared it will
return true. Please refer to the discussion of the following mail thread:
http://www.mail-archive.com/l4-hackers@os.inf.tu-dresden.de/msg05162.html

Subject: [PATCH 03/15] Sigma0: raise sigma0's priority to maximum.
When sigma0 runs on a lower priority than the rest of the threads in the system
it might come to the point that while answering a page fault or I/O memory area
request the timeslice of the caller (core-pager) gets fully consumed. As long as
other threads are still executable and don't block sigma0 won't do progress
anymore, because it runs at the lowest priority. This commit simply sets
sigma0's priority to the highest in the system.

With this patch the comport are tried to read out from the BIOS Data Area
on x86 machines. The BDA Area are part of the first physical page and may
contain the non-default io ports of the comport.
When used together with 'bender' from the 'morbo' toolchain, even serial PCI
cards (also Intel's AMT Serial Over Line adapter) are detected automatically.
