551b17591c ssh_terminal: handle detached term in event loop
Rather than calling 'ssh_disconnect' from within the Terminal session,
flag the detached terminal in the session and let the event loop do the
cleanup. Otherwise it might happen that the 'ep' (handling the Terminal
session) as well as the 'pthread.0' (executing the ssh event loop) end
up both triggering the cleanup concurrently.

5db2971903 base-hw/arm_v7a: Mark r1 as out in Kernel::call64
In case of arm_v7a Kernel::call64 the syscall will use both r0 and r1 as
output registers. Unfortunately the inline asm does not reflect this and
only r0 is explicitly specified as output. GCC manages to produce output
which we'd like to see. Clang on the other hand takes adventage of the fact
r1 should not be touched by swi and produces fewer instructions which do
what the code describes, but not what we actually want.

Basically the code which we want and is generated by GCC is:
  svc     0
  mov     r2, r0
  mov     r0, r1
  mov     r1, r2
  bx      lr

Clang on the other hand generates correct assembly given the code, but
incorrect given what the function is supposed to do:
  svc     0
  mov     r1, r0
  mov     r0, #0
  bx      lr

Both GCC and clang generate the same, expected assembly output when r1
is marked as output register from the inline asm swi call.

might be this is a part of some unfinished feature. This patch just does

30b8f4efc8 gems: import Genode-specific code of the CBE
The CBE repository contained a lot of Genode-specific code despite the fact
that the CBE core logic is not bound to Genode in any way. Therefore the
Genode-specific CBE code is moved to the 'gems' repository to form part of
Genode mainline. The remaining CBE code becomes a port in Genode instead of
being invoked as sub-repository.

The commit combines the following work steps:

* add all files removed from CBE repository
* add CBE port files
* make all CBE libs and targets build again
* make all CBE run scripts succeed again
* make all CBE recipes build again
* make CBE autopilot succeed again
* let CBE autopilot use 'libsparcrypto' contrib dir and Genode build dir
  instead of '.ci' dir in CBE contrib dir (remove '.ci' dir from CBE repo)
* let CBE autopilot always check for all ports
* make CBE autopilot directly executable
* fix license headers in all Genode CBE files
* remove unused VFS replay component
* remove unused CBE test
* remove unused external crypto
* remove unused files in run dir
* remove unused external trust anchor
* add cbe_tester test to autopilot list
* get rid of directories 'include/cbe_*' and 'include/utils'

b9869b666a dde_bsd: use bsd_task to handle I/O
Originally, the kernel code should have been executed within the
context of the main task like it is done in dde_linux. The initial
port of the HDA driver, however, did not required doing so and the
session called code directly.

When using USB device, that is no longer possible as we have to
suspend the execution during the execution of the kernel code. So
we pass in the audio data and schedule the kernel.

2ec398e550 dde_bsd: use timeout framework for time handling
With this commit the timer back-end uses the timeout framework to
schedule any occuring timeouts and for providing the current time.
For now there is only one timeout, the unsolicited azlia codec event
and therefore the timeout queue consists of solely one timeout object.

we have to block until the delay is completed.

53a990579b base: Fix UAF in Genode::Pd_session_component::free
This was discovered when building the code with clang instead of GCC. In
this setup the run/ping on base-hw/arm_v8a/virt_qemu would crash
on shutdown due to uncaught Deref_unconstructed_object exception thrown
for Genode::Reconstructible<Genode::Account<Genode::Ram_quota>>. The
specific instance throwing this exception was
Pd_session_component::_ram_account. My investigation exposed the
following problem:

1. The Pd_session_component has a _sliced_heap member backed by
   _constrained_ram_alloc which in turn uses Pd_session_component itself
   as its Ram_allocator.
2. When ~Pd_session_component is called it first destroys _ram_account,
   followed by _signal_broker.
3. The signal broker holds a reference to
   Pd_session_component::_sliced_heap as Signal_broker::_md_alloc.
4. The base-hw implementation of ~Signal_broker destroys some contexts
   and does this by calling Genode::destroy on some slabs using the
   _md_alloc (ref to Pd_session_component::_sliced_heap).
5. The Genode::Slab calls the Ram_allocator::free which ends up calling
   Pd_session_component::free.
6. The Pd_session_component::free can among other things call replenish
   method on Pd_session_component::_ram_account which has already been
   freed at this point.

From my POV calling replenish at this point is basically an undefined
behavior. The Genode::Constructible holding the Genode::Account was
already detroyed at this point. GCC builds happen to somehow manage to
go through the -> operator call without raising any alarms, while clang
builds trip on the _check_constructed() call.

This fix moves the _ram_account a bit higher in class declaration to
ensure its destroyed after _sliced_heap. This seems like the simpliest
solution for this problem.

1d826a2c48 base-hw: do direct syscall when run/pause a VCPU
Instead of calling core to run/pause a VCPU, go directly to the kernel.
Apart from the performance win, it would otherwise involve a more complex
protocol, when a VCPU on another core has to be removed from the scheduler.
Core's entrypoint handling those request runs on the boot-cpu only.

40445d7011 base: extend vm_session API with native vcpu cap
To enable the interaction of a VMM with the kernel directly,
a hidden RPC gets introduced. It allows a kernel-specific
base-library implementation of the Vm_session::Client to request
a kernel-specific capability to address a VCPU, e.g., to
run/stop it.

3d2b0cab93 libc: implement SNDCTL I/O control handling
In the same vein as the terminal and block I/O controls, the sound
controls are implemented via poperty files and match the OSS
API ([1] features a nice overview while [2] is v3 and [3] gives
in-depth information on the current v4.x API we eventually might want
to implement).

  [1] https://wiki.freebsd.org/RyanBeasley/ioctlref/
  [2] http://www.opensound.com/pguide/oss.pdf
  [3] http://manuals.opensound.com/developer/

The controls currently implemented are the ones used by the cmus OSS
output plugin, which was the driving factor behind the implementation.
It uses the obsolete (v3) API and does not check if the requested
parameter was actually set, which should be done according to the
official OSS documentation.

At the moment it is not possible to set or rather change any
parameters. In case the requested setting differs from the parameters
of the underlying Audio_out session - in contrast to the suggestion in
the OSS manual - we do not silently adjust the parameters returned
to the callee but outright fail the I/O control operation.

The following list contains all currently handled I/O controls.

  * SNDCTL_DSP_CHANNELS sets the number of channels. We return the
    available channels here and return ENOTSUP if it differs from
    the requested number of channels.

  * SNDCTL_DSP_GETOSPACE returns amount of playback data that can
    be written without blocking. For now it amounts the space left
    in the Audio_out packet-stream.

  * SNDCTL_DSP_POST forces playback to start. We do nothing and return
    success.

  * SNDCTL_DSP_RESET is supposed to reset the device when it is
    active before any parameters are changed. We do nothing and return
    success.

  * SNDCTL_DSP_SAMPLESIZE sets the sample size. We return the
    sample size of the underlying Audio_out session and return ENOTSUP
    if it differs from the requested number of channels.

  * SNDCTL_DSP_SETFRAGMENT sets the buffer size hint. We ignore the
    hint and return success.

  * SNDCTL_DSP_SPEED sets the samplerate. For now, we always return
    the rate of the underlying Audio_out session and return ENOTSUP
    if it differs from the requested one.

This commit serves as a starting point for further implementing the
OSS API by exploring more users, e.g. as VirtualBox/Qt5/SDL2 audio
backend or a more sophisticated progam like sndiod.

bff624c75a test/entrypoint: extend timeout interval
At least on some PIT-based platforms (x86_32 + pistachio/okl4/sel4), we run
into trouble with the reworked timeout framework that now proccesses all
pending timeouts before calling their handlers. This order change leads to a
higher rate of handling of short periodic timeouts in the timer driver which
can cause lower prioritized components to starve. Especially, if submitting
signals (from timer to client) isn't cheap (as is the case on qemu + pistachio
for example).

7fbb245710 os: add VirtIO device helper classes.
To simplify writing native VirtIO drivers for Genode add helper classes
representing VirtIO device and queue. The queue implementation should
be platform independant. The device abstraction however is closely tied
to the VirtIO transport being used (PCI/MMIO). Both PCI and MMIO
implementations expose the same public API so the actual driver logic
should be the same regardless of which transport is used.

Its also important to note that the PCI version of Virtio::Device
currently does not support MSI-X interrupts. Unfortunately my kowledge
about PCI bus is very limited and my main area of interest was to get
VirtIO drivers working on virt_qemu ARM/Aarch64 platform. As such all
the VirtIO drivers I plan to submit will work with PCI bus, but might
not use some extended capabilities.

9bd548c4bd os: add platform_drv config generator for virt_qemu
The VirtIO device configuration on Qemu is dynamic. The
order and presence of different command line switches affects
base address and interrupt assignment of each device. One could
probably hard-code the necessary switches and resulting XML ARM
platform driver configuration in each run script, but this seems
like troublesome and hard to maintain solution.

This patch explores an alternative approach to the problem.
It implements a ROM driver which probes the address space region
Qemu virt machines assign to VirtIO MMIO devices and exposes the
result as XML via a ROM session. This XML output can be fed directly
as config to the generic ARM platform driver.

abefca500b libc: fix deadlock in pthread_cond_timedwait/signal()
The deadlock occured with three concurrently running threads: two
waiters calling pthread_cond_timedwait() and one signaller calling
pthread_cond_signal().

If waiter W1 hits its timeout, the signaller may have called
pthread_cond_signal(), detected this waiter and posted the internal
'signal_sem' concurrently. Then, the signaller waits for 'handshake_sem'
to ensure the waiter got woken up.

Waiter W1 can't consume the 'signal_sem' post by
'sem_wait(&c->signal_sem)' because another waiter W2 may have consumed
the post already above in sem_wait/timedwait(). Waiting for a post on
'signal_sem' would block the waiter W1 in perfect deadlock with
signaller on 'handshake_sem'. As W1 also owns 'counter_mutex' in this
situation, waiter W2 would block when trying to aquire 'counter_mutex'
and can't resolve the situation.

So, W1 does nothing in this case and we accept the spurious wakeup on
next pthread_cond_wait/timedwait().

04821b1abc nitpicker: apply focus change w/o input events
This patch fixes the corner case where the keyboard focus is defined
independently from user interactivity, e.g., the activation of a
screensaver or lock screen.

In this case, nitpicker would update its internal focus state not before
the next input event is handled. Should this input event be a press
event, this event would wrongly be delivered to the prior focused
session. Another problematic situation is the initial state before the
very first input event occurs. Since the focus remains undefined until
the first input event is handled, an initial key press event would not
be delivered.

This is a regression caused be the transition to the event-session
interface and the removal of the nitpicker's periodic way of operation.
The patch fixes the problem by applying pending focus changes not only
at the input processing but also on the code path that responds to focus
changes (e.g., focus-rom update).

e0d9a04f67 libc: resolve circular dependency in fork
This patch is a follow-up for the commit "libc: use monitor for fork".
It removes the use of the monitor mechanism from the
'Local_clone_service::close' RPC function because the fork_ep must stay
responsive for the destruction and creation of 'Child' objects.

0d61029d7e depot_deploy: move affinity to <affinity> sub node
The initial implementation of the affinity configuration in
"depot_deploy: support affinity configuration" added the affinity
location attributes to the <start> node of the deploy config. This patch
moves the information into a dedicated <affinity> sub node as done by
the init configuration. So the context of the attributes 'xpos', 'ypos',
'width' and 'height' becomes clear.

It also fixes a usability issue in Sculpt that occurred during testing:
When configuring multiple components with custom affinities, the
resources dialog of later components would wrongly display the state of
earlier components instead of displaying the fresh (default) state. The
resulting configuration would then not match the displayed information.
This is fixed by resetting the dialog state.

As another minor cosmetic change, the patch adds a line break in front
of copied <config> or <heartbeat> nodes.

2eb8c5e21a net: move ascii_to() into Net namespace
The combination of Net::Mac_address and
Genode::ascii_to(Net::Mac_address) required shaky quirks in several
places because GCC is not able to resolve the ascii_to overload if
base/xml_node.h was included to early. The current solution moves the
several ascii_to overloads "closer" to the Net types by putting them
into the Net namespace, where GCC reliably picks them up.

Hence, co-locating the ascii_to() utility with the overload type in the
same scope/namespace is good practice.

This patch removes the now obsolete <nic/xml_node.h> header file.

be14e68a83 sculpt/vimrc: 'set nowritebackup'
By default, Vim renames a written file to a backup file suffixed with
"~" before writing the current buffer to a new file. Consequently, there
exists an intermediate state when no file exists. Should a client watch
such a file to obtain dynamic configuration info, it observes the empty
state.

Some components have builtin heuristics for such a situation. In
particular, the window layouter falls back to a predefined default
'rules' if no rules are provided as a file. So when interactively
editing window-layouter rules using Vim, it can happen that the manually
maintained rules get overwritten by the default rules.

By setting 'set nowritebackup', we can sidestep this issue by preventing
Vim from producing the bad intermediate state.

328a4fa644 nitpicker: update hovering on view-stack changes
With the change of nitpicker to the event session interface, the
formerly periodic hovering updates moved to the - now sporadic - input
processing. This has the unfortunate side effect that hovering changes
caused by non-user-input, in particular view-stack changes issued by the
GUI clients that change the view under the current pointer position,
would no longer be reported immediately but only after receiving the
next incoming input event.

This patch reworks the hover handling such that potential hovering
changes due to view-stack operations are evaluated immediately by
those operations, covering the update of the hover report and the
generation of artificial enter/motion events.

17a6318ad6 vfs: process all acks in each iteration
This patch solves a corner case where one long-active job (e.g.,
read-ready request) stays at the beginning of the '_active_jobs' queue
without an ack. In this case, the '_try_acknowledge_jobs' method would
wrongly stop processing the subsequent acknowledgements. In practice,
this can lead to a delayed sending of acknowledgements until new I/O or
client requests occur. In particular, Vim in Sculpt's inspect window
sometimes did not immediately respond to key presses during tab
completion. Here, the read-ready request of the terminal prevented the
acknowledgement for read of directory entry from being delivered until
the next key was pressed.

a59b69758b sculpt: remove deferred GUI initialization
The sculpt manager used to defer the initialization of the GUI until
nitpicker's first display report became ready. This way, Sculpt was able
to run headlessly even if the framebuffer driver failed to start up.
Thanks to #3827, nitpicker no longer depends on a working framebuffer
driver. So the sculpt manager is safe to rely on nitpicker in any case,
simplifying the code.

c7d9b2ca92 nitpicker: fix mode change for requested fb
This is a follow-up commit to "nitpicker: make framebuffer and input
optional". It restores the dynamic mode-change support when using
'request_framebuffer="yes"' as needed in scenarios where multiple
nitpicker instances are used in a cascaded way. E.g., Sculpt's
Leitzentrale. The previous version missed to reconstruct the
'_fb_screen' on mode changes.

556a5c8086 libc: clean up 'clock_gettime' handling
This patch untangles the dependency of VFS operations that need RTC
information from the 'clock_gettime' libc function that must never be
called from the libc kernel context.

- The 'Rtc' class uses the VFS directly for reading the rtc file instead
  of relying on libc functions.

- The 'Rtc' instance has become part of the 'Kernel' instead of
  being construced as a side effect of the first call of
  'clock_gettime'.

- Changed 'Rtc::read' to return a timespec value, which has a higher
  precision than the formerly used time_t value.

- The 'Rtc::read' returns a value with the relative 'current_time'
  already applied. The former handling of subsequent rtc-value
  updates has been rewritten to become more logical.

- The 'Vfs_plugin' no longer calls 'clock_gettime' but the new
  kernel-level 'Current_real_time' interface.

852ab79359 Move atexit handling from base lib to libc
This patch untangles the interplay of the base library and the libc
during the exit handling.

- The CXA ABI for the atexit handling is now provided by the libc.
  For plain Genode components without libc dependency, __cxa_atexit
  is a no-op, which is consistent with Genode's notion of components.

- The 'abort' implementation of the base library no longer calls
  'genode_exit' but merely 'sleep_forever'. This way, the cxx library
  no longer depends on a 'genode_exit' implementation.

- The libc provides 'atexit' support by storing metadata on the
  libc kernel's heap now, thereby eliminating the former bounded
  maximum number of atexit handlers.

- Shared-library dtors are no longer called via the atexit mechanism
  by explicitly by the dynamic linker. This slightly changes the
  call order of destructors (adjustment of the ldso test). Functions
  marked as destructors are called after the atexit handlers now.

- The libc executes atexit handlers in the application context,
  which supports the I/O operations in those handles, in particular
  the closing of file descriptors.

2e22498e5a nitpicker: no framebuffer and input by default

9662d89cfb Replace input filter with event filter
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.

The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.

The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.

c502e1d095 input_filter: prepare for refactorization
This patch brings the input filter into a shape that is easier to
re-mold into an event filter, reversing the client/server roles of
the component.

* The 'Sink &destination' is no longer passed as constructor argument
  to the individual filters but passed as argument to the 'generate'
  method. This way, the final destination does not need to exist at
  the construction time of the filter chain but can be created on
  the fly (clearing the way for using 'Event::Client::with_batch').

* A new 'Source::Filter' interface with the 'apply' method aids the
  cascading of filters during 'generate'. The modules now implement
  the 'Source::Filter::filter_event' interface instead of the
  'Source::Sink::submit_event' interface.

* Since the 'Sink &destination' is no longer a member of the filter
  modules, character-repeat events can no longer be emitted in an
  ad-hoc way. Instead, the character-repeat mechanism now invokes
  a new 'Trigger::trigger_generate' hook that prompts the execution
  of the regular 'generate' mechanism by the main program.

This patch is supposed to leave the semantics of the input filter
unchanged (validated by the input_filter.run script).

7bac1ec7e5 Adapter for connecting input and event servers
This is an intermediate helper component for the transition of input
servers into event clients. It works analogously to the
input_event_bridge but it connects servers instead of clients.
In particular, it can act as glue between a traditional input driver
that provides an input service and the event filter that provides an
event service. Thanks to this component, each driver can be migrated to
the event-client interface individually.

c81af531a3 Turn framebuffer drivers into capture clients
This patch replaces the use of the "Framebuffer" session interface by
the new "Capture" session interface in all framebuffer drivers. Thanks
to this change, those drivers have become mere clients of the nitpicker
GUI server now, and are no longer critical for the liveliness of the GUI
server.

The patch touches the following areas:

- The actual driver components. The new versions of all drivers have
  been tested on the respective hardware. Generally, the drivers
  have become simpler.

- The drivers_interactive packages for various boards. The drivers
  subsystem no longer provides a "Framebuffer" service but needs a
  valid route to the "Capture" service provided by nitpicker.

- The driver manager of Sculpt OS.

- This patch changes the role of the test-framebuffer component from a
  framebuffer client to a capture server so that drivers (capture clients)
  can be directly connected to the test component without the nitpicker
  server.

- Framebuffer driver no longer support the unbuffered mode.

- The fb_bench.run script is no longer very meaningful because it
  interplays solely with nitpicker, not with the driver directly.

- All run scripts for graphical scenarios and the related depot
  archives got adapted to the change.

ef741ef80d Change pixel format to 32 bits per pixel
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.

The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.

e56dd15a4b vfs: extend <zero> fs to limit amount of zeros
Setting the 'size' attribute will restrict a reader to consume
0s up to the specified amount per VFS handle. The attribute is

maximum of the addressable memory on the platform.

This addition comes in handy when needing to provide a synthetic
empty file with a fixed size.

103ae9df4a block_tester: limit batching in sequential test
So far the condition whether to spawn a new job or not depended on
the amount of data already processed. This could lead to spawning
more jobs than necessary if batching is used and in return could
result in creating invalid requests in case the tested block session
is not large enough.

In addition to checking the amount of data the test now stores the
number of the last block and checks if the current request is in
range. This properly limits the total amount of requests.

78497c03ca base-linux: enabled seccomp
base-linux uses seccomp to reduce the available system calls
to the minimum set needed to run base-linux. There are still
some syscalls that allow accessing global state which should
be further reduced.

The combination of seccomp and socket descriptor caps should
provide an intermediate level of security for base-linux
thereby enabling base-linux as a migration path from using
the Linux kernel to the use of microkernel-based Genode.

0de54cddaa gdb_monitor: hide exceptions during create_thread
This patch is a workaround for the missing implementation of
'Pd_session::transfer_quota' interface by the GDB monitor's PD service.
The missing implementation becomes problematic with the changes of #3750
that enabled the cap-quota accounting for core's CPU service.

In regular scenarios without the GDB monitor, the client of
'Cpu_session::create_thread' deals with Out_of_caps or Out_of_ram by
upgrading the CPU session's cap and RAM quotas. This, in turn, results
in a sequence of 'transfer_quota' operations at the parent.

Since GDB monitor implements a custom PD service, these 'transfer_quota'
calls try to transfer quota between sessions provided by core and those
provided by the GDB monitor. This does of course not work. To fix this
issue, the GDB monitor needs a major overhaul. This patch side-steps
the problem by handing Out_of_caps and Out_of_ram from the debuging
target.

f1427fc02a dde_bsd: remove configration attributes
The driver always opens the audio device in duplex mode, i.e.,
playback and recording. Setting the 'playback' or 'recording' attribute
only influnces the service announcement. Due to changes made in a more
recent OpenBSD release recording must be set enabled explicitly anyway.
Since we already provide the interface that mirrors the one used by
OpenBSD 1:1 in the configuration use that and the remove the additional
config attributes.

42fddf8390 Cleanup shared-object support mechanics
The former ldso-startup static library (now called ldso_so_support) is
used to spice each shared object/library with local support code for the
dynamic linker (execution of static constructors and ARM-EABI).
Therefore, the library must be statically linked to each dynamic
library.

As a result recipes for dynamic libraries must always depend on the "so"
API, which makes ldso_so_support.mk and so_support.c available
independent of "base". Additionally, ldso_so_support is also provided in
the libc API to cut the dependency early for libc/posix libraries.

64bc008c3a core: fix inconsistent state after failed 'trace'
This patch fixes the handling of the corner case where the allocation of
a trace buffer throws 'Out_of_caps' or 'Out_of_ram'. Under this
circumstance, the '_buffer' would still be flagged with the 'size',
which prevented any subsequent allocation attempt. This patch fixes the
problem by initializing the 'size' after the potentially throwing
allocation.

The problem triggered with the test-trace_logger after the accounting of
core's TRACE service (replacing the 'Allocator_guard' by
'Constrained_ram_allocator') became more accurate.

9d67f9fc8e Remove Allocator_guard
This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.

The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.

The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.

f0c4fc1e22 sandbox: defer requests for upcoming server
The sandbox library supports the forwarding of session requests from the
outside to one of the hosted children according to a policy. This patch
introduces the distinction between two cases, which previously triggered
the denial of the session request.

- There exists no matching policy for the requested session
- There exists a matching policy but the referred server child
  does not exist (yet)

Whereas the proper response to the first case is the denial of the
request, the second case can occur in situation where a dynamic init is
used to implement a staged startup, for example via the deploy
mechanism. In such cases, a policy may exist as a static rule while the
server has not been started yet. This patch changes the behavior such
that such requests are stalled.

The patch is accompanied with test cases for exercising both situations.

132569d12b base-linux: socket descriptor caps for RPC
On Linux, Genode used to represent each RPC object by a socket
descriptor of the receiving thread (entrypoint) and a globally-unique
value that identifies the object. Because the latter was transferred as
plain message payload, clients had to be trusted to not forge the
values. For this reason, Linux could not be considered as a productive
Genode base platform but remained merely a development vehicle.

This patch changes the RPC mechanism such that each RPC object is
represented by a dedicated socket pair. Entrypoints wait on a set of
the local ends of the socket pairs of all RPC objects managed by the
respective entrypoint. The epoll kernel interface is used as the
underlying mechanism to wait for a set of socket descriptors at the
server side.

When delegating a capability, the remote end of the socket pair is
transferred to the recipient along with a plaintext copy of the
socket-descriptor value of the local end. The latter value serves as a
hint for re-identifiying a capability whenever it is delegated back to
its origin. Note that the client is not trusted to preserve this
information. The integrity of the hint value is protected by comparing
the inode values of incoming and already present capablities at the
originating site (whenever the capability is invoked or presented to the
owner of the RPC object).

The new mechanism effectively equips base-linux with Genode's capablity
model as described in the Chapter 3 of the Genode Foundations book.
That said, the sandboxing of components cannot be assumed at this point
because each component has still direct access to the Linux system-call
interface.

This patch is based on the extensive exploration work conducted by
Stefan Thoeni who strongly motivated the inclusion of this feature into
Genode.

150d143755 os: use Request_stream API in NVMe driver
As a result of the API change the memory handling could be simplified.
Since the Block session dataspace is now directly used for DMA, we
actually only have to provide the memory for setting up PRP lists for
large requests (for the moment more than 8 KiB of data).

As we limit the maximum data transfer length to 2 MiB, we get by with
just a page per request. Those memory is allocated beforehand for the
maximum number of I/O requests, which got bumbed to 512 entries. Since
not all NVMe controllers support such large a maximum data transfer
length and this many entries, especially older ones, the values are
capped according to the properties of the controller during
initialization. (The memory demands of the component are around 3 MiB
due to setting up for the common case, even if a particular controller
is only able to make use of less.)

(Although there are controllers whose maximum memory page size is more
than 4K, the driver is hardcoded to solely use 4K pages.)

In addition to those changes, the driver now supports the 'SYNC' and
'TRIM' operations of the Block session by using the NVMe 'FLUSH' and
'WRITE_ZEROS' commands.

Fixes #3702.

2912096f6e vfs: distinguish NO_PERM from NO_ENTRY in unlink
This patch changes the 'Single_file_system' to return NO_PERM only if
the to-be-unlinked file corresponds to the single file. This way, a
<rom> co-mounted with a <ram> file-system does not stand in the way of
unlinking files from the <ram>. The concrete symptom occurred the
following scenario:

  <vfs>
    <dir name="home">
      <ram/>
      <rom name="..."/>
    </dir>
  </vfs>

The following sequence of commands wrongly resulted in "Operation not
permitted":

 $ mkdir -p /home/a/b/c
 $ rm -f /home/a/b/c/d

ba55409c86 nic_router: keep dyn IP when updating domain obj
When updating the domain object of interfaces that stay with the same domain
during a reconfiguration, until now, the normal "detach raw" function was used.
This caused the old domain object to discard a dynamic IP config as all
interfaces detached. This caused interfaces also to discard network links
established with the old configuration although it wasn't necessary. Thus, now
we use a dedicated "detach" in case that an interface actually stays with its
domain. This new "detach" doesn't decrease the interface counter of the domain,
so, it'll not discard its dynamic IP config. If, however, during a
reconfiguration, there's no interface calling this function (all interfaces
move to another or no domain), the dynamic IP config is still discarded as
expected.

to handle packet headers other than that of DHCP.

DHCP-reply packets at an interface only when the DHCP client its constructed.

under ARM:

* read out I-, and D-cache line size at runtime and use the correct one
* remove 'update_data_region' call from unprivileged syscalls
* rename 'update_instr_region' syscall to 'cache_coherent_region' to
  reflect what it doing, namely make I-, and D-cache coherent
* restrict 'cache_coherent_region' syscall to one page at a time
* lookup the region given in a 'cache_coherent_region' syscall in the
  page-table of the PD to prevent machine exceptions in the kernel
* only clean D-cache lines, do not invalidate them when pages where
  added on Cortex-A8 and ARMv6 (MMU sees phys. memory here)
* remove unused code relicts of cache maintainance

In addition it introduces per architecture memory clearance functions
used by core, when preparing new dataspaces. Thereby, it optimizes:

* on ARMv7 using per-word assignments
* on ARMv8 using cacheline zeroing
* on x86_64 using 'rept stosq' assembler instruction

Genode OS Framework release 20.11 | 2020-11-27
##############################################
| Genode 20.11 brings Sculpt OS to 64-bit ARM hardware, introduces dynamic
| CPU-load balancing, and enables multicore virtualization on ARM. Driver-wise,
| the release improves audio on PC hardware, and adds VirtIO networking support.
ARM 64-bit has been a recurring theme of the Genode releases this year and the
just released version 20.11 is no exception. We are proud to announce that our
Genode-based custom general-purpose OS called Sculpt has come to life on
64-bit ARM hardware, namely the NXP i.MX8 EVK board. This is the result of
intensive work on the framework's driver architecture for ARM and several
SoC-specific device drivers. Closely related to this line of work is the new
ability to run multicore virtual machines on ARM.
Another highlight of version 20.11 is a new CPU balancing mechanism, which
automates the dynamic assignment of threads to CPU cores for complex
workloads. With traditional operating systems, such policies are normally part
of the OS kernel. Thanks to Genode's component architecture, we are able to
implement such potentially complex policies in the form of an optional
component, which offers ultimate flexibility while keeping the kernel
untainted by complex heuristics.
Further topics of the current release are improved power management and audio
support on PC hardware, a new OSS API emulation that allows for the
reuse of popular audio applications on Genode, and new support for VirtIO
networking. The full picture is given by the

Sculpt OS release 20.08 | 2020-09-17
####################################
| Version 20.08 of the Sculpt operating system refines the user experience
| and becomes able to host the Chromium-based Falkon web browser.
The new version of Sculpt OS is based on the latest Genode release
[https://genode.org/documentation/release-notes/20.08 - 20.08].
In particular, it incorporates the
[https://genode.org/documentation/release-notes/20.08#The_GUI_stack__restacked - redesigned GUI stack]
to the benefit of quicker boot times, improved interactive responsiveness, and
better pixel output quality.
It also removes the last traces of the
[https://genode.org/documentation/release-notes/20.05#Retired_Noux_runtime_environment - noux runtime].
Fortunately, these massive under-the-hood changes do not disrupt the
user-visible surface of Sculpt. Most users will feel right at home.
Upon closer inspection, there are couple of new features to appreciate. The
CPU-affinity of each component can now be restricted interactively by the user,
components can be easily restarted via a click on a button, font-size changes
have an immediate effect now, and the VESA driver (used when running Sculpt in
a virtual machine) can dynamically change the screen resolution.
Thanks to our continuous efforts of strengthening of the base system, Sculpt
OS has become able to host a first version of the Chromium-based Falkon web
browser from an installable package. Even though this version is still rough
around the edges and unoptimized, it already enables Sculpt users to casually
browse the modern web without the need for a virtual machine.
The updated [https://genode.org/documentation/articles/sculpt-20-08 - manual]
goes into detail about the use of the new system.
The ready-to-use system image for version 20.08 is available at the
[https://genode.org/download/sculpt - Sculpt download page].
Genode OS Framework release 20.08 | 2020-08-28
##############################################
| With Genode 20.08, the low-level GUI stack underwent a profound redesign,
| the Chromium web engine comes to life, the i.MX8 support covers clock and
| power management, and the CBE block encrypter becomes highly modular.
The most stunning feature of Genode 20.08 is most certainly the new ability
to host the Chromium web engine as native component in the form of the Falkon
web browser. This long-time project involved overcoming countless road
blocks along the way to the great benefit of Genode's users at large: building
bridges between 3rd-party build systems and Genode, covering seemingly obscure
corner cases of POSIX, solving instruction-cache invalidation issues on ARM -
just to name a few.
Under the hood, we took the release cycle as opportunity to tackle a major
surgery of the low-level GUI stack that we planned for more than two years.
The architectural change lays the groundwork for swapping out graphics and
input drivers on the fly without reboot. It also paves the ground for features
like screen capturing and remote desktop scenarios in a privacy-protecting
way.
On our mission of bringing the driver support for the 64-bit ARM-based i.MX8
SoC on par with our driver coverage on Intel PCs, the release introduces a
platform driver specifically for this SoC that covers clock and power
management. One step closer to using Sculpt OS on the MNT Reform laptop.
Furthermore, Genode's custom block encrypter called CBE received continuous
development. In particular, the cryptographic algorithm and trust anchor
have become pluggable modules. This will allow for tailoring the CBE to
custom products - like hardware trust anchors - without changing its
implementation.
These and many more improvements are covered in detail in the
[https:/documentation/release-notes/20.08 - release documentation of version 20.08...]
Genode OS Framework release 20.05 | 2020-05-28
##############################################
| Version 20.05 wraps up the consolidation of Noux with the C runtime,
| advances the device-driver infrastructure and virtualization support on ARM,
| reaches feature-completion of our block encryptor, and leverages seccomp for
| sandboxing components on top of Linux.
It has become almost a tradition to dedicate the spring release to topics
under the hood of the Genode OS framework, taking the time for careful
consolidation, and architectural improvements.
On the latter account, the Linux version gained an architectural revamp of its
inter-component communication model, leveraging the combination of the
seccomp and epoll kernel mechanisms to enable Genode's capability-based
security concept on this kernel. The new version applies strict sandboxing
to each component individually. In particular, the host file system is
shielded from Genode components and Genode's least-privilege access-control
scheme comes into effect.
As the second prominent architectural topic, the release features new
device-driver infrastructure for the ARM universe along with a unified
version of the formerly distinct virtual machine monitors for ARMv7 and
ARMv8. These are important steps to bring Genode on ARM to parity with the
x86 version.
Further highlights of the release are the first feature-complete version
of our custom block-encryption component, the improved management of CPU
affinities on x86, and new tracing utilities. Last but not least, the
release is accompanied with an updated version of the Genode Foundations
book, reflecting the changes of the framework since one year ago.

| user interface for a more intuitive and logical user experience.
With the release of Sculpt version 20.02, we follow our
[https://genode.org/about/road-map - roadmap's] mission to make Sculpt OS
easier to approach. In particular, we
[https://genodians.org/nfeske/2020-01-06-pending-sculpt-ui - identified] the
reliance on a command-line interface as a potential barrier of entry. As
Sculpt OS is not a Unix-like system, it should not require any Unix know-how
from the user. To relieve users from this burden, Sculpt 20.02 introduces
a custom graphical file browser and editor that can be used for interactively
inspecting and tweaking the state of the system. The traditional command-line
interface is still present as a fallback for advanced tasks though.
The updated [https://genode.org/documentation/articles/sculpt-20-02 - manual]
goes into detail about the use of the new system.
Thanks to the work of seasoned Genode developers, many software packages are
already available for the new version. These include virtual machine monitors
like VirtualBox, performance-monitoring tools, GUI components, Genode's custom
Unix runtime, and several applications and games. In particular, the software
depots offered by alex-ab, cnuke, skalk are worth exploring.

===============================================
Release notes for the Genode OS Framework 20.11
===============================================
Genode Labs
With Genode 20.11, we focused on the scalability of real-world application
workloads, and nurtured Genode's support for 64-bit ARM hardware. We thereby
follow the overarching goal to run highly sophisticated Genode-based systems
on devices of various form factors.
When speaking of real-world workloads, we acknowledge that we cannot always
know the exact behavior of applications. The system must deal gracefully with
many unknowns: The roles and CPU intensity of threads, the interplay of
application code with I/O, memory-pressure situations, or the sudden fragility
of otherwise very useful code. The worst case must always be anticipated. In
traditional operating systems, this implies that the OS kernel needs to be
aware of certain behavioral patterns of the applications, and has to take
decisions based on heuristics. Think of CPU scheduling, load balancing among
CPU cores, driving power-saving features of the hardware, memory swapping,
caching, and responding to near-fatal situations like OOM.
Genode allows us to move such complex heuristics outside the kernel into
dedicated components. Our new CPU balancer described in Section
[CPU-load balancing] is a living poster child of our approach. With this
optional component, a part of a Genode system can be subjected to a CPU-load
balancing policy of arbitrary complexity without affecting the quality of
service of unrelated components, and without polluting the OS kernel with
complexity.
A second aspect of real-world workloads is that they are usually *not*
designed for Genode. To accommodate the wealth of time tested applications, we
need to bridge the massive gap between APIs of olde (think of POSIX) and
Genode's clean-slate interfaces.
Section [Streamlined ioctl handling in the C runtime / VFS] shows how the
current release leverages our novel VFS concept for the emulation of
traditional ioctl-based interfaces. So useful existing applications come to
live without compromising the architectural benefits of Genode.
Platform-wise, the new release continues our mission to host Genode-based
systems such as [https://genode.org/download/sculpt - Sculpt OS] on 64-bit
ARM hardware. This work entails intensive development of device drivers and
the overall driver architecture.
Section [Sculpt OS on 64-bit ARM hardware (i.MX8 EVK)] reports on the
achievement of bringing Sculpt to 64-bit i.MX8 hardware. This line of work
goes almost hand in hand with the improvements of our custom virtual machine
monitor for ARM as outlined in Section [Multicore virtualization on ARM].
CPU-load balancing
##################
Migrating load over CPUs may be desirable in dynamic scenarios, where the
workload is not known in advance or too complex. For example, in case of POSIX
software ported to Genode, amount and roles of threads and processes can
generally not planned for. With the current release, we add an optional CPU
service designated for such dynamic scenarios. The new component called
[https://genodians.org/alex-ab/2020-11-16-cpu-balancer - CPU balancer] is able
to monitor threads and their utilization behaviour. Depending on configured
policies, the balancer can instruct Genode's core via the CPU session
interface to migrate threads between CPUs.
[image cpu_balancer]
The CPU balancer intercepts the interaction of a Genode subsystem
(workload) with core's low-level CPU service.
This feature requires a kernel that supports thread migration, which are
Fiasco.OC, seL4, and to some degree the NOVA kernel. For the NOVA kernel,
solely threads with an attached scheduling context can be migrated, which are
'Genode::Thread' and POSIX pthread instances. Genode's entrypoint and virtual
CPU instances are not supported.
The feature can be tested by the scenario located at _repos/os/run/cpu_balancer.run_.
Further information regarding policy configuration, a demo integration into
Sculpt 20.08, and a screencast video are available as a dedicated

Sculpt OS on 64-bit ARM hardware (i.MX8 EVK)
############################################
Within the last year, a lot of effort was put into Genode's support for ARM
64-bit hardware. A consequent next step was to port Sculpt OS to the i.MX8 EVK
board, which we have used so far as reference platform. With the current
release, we proudly present the first incarnation of Sculpt OS for this board.
In contrast to the original x86 PC variant, this first ARM version ships with
a static set of devices inside the drivers subsystem. No device manager
component probes for the used hardware and starts drivers on demand. Instead,
the set of drivers defined in the _drivers_managed-imx8q_evk_ package enables
USB HID devices to make use of mouse and keyboard peripherals connected to the
board. It drives the SD-card, which can be used as storage back end for
Genode's depot package management. Finally, it contains drivers to manage the
display engine and the platform's device resources.
With Sculpt OS for ARM 64-bit, we not only aim for classical desktop/notebook
systems - like on x86 - but also for embedded consumer hardware like phones
and tablets. In order to leverage this goal, we enabled support for
[https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/i-mx-8-series-accessory-boards:i.MX8-ACCESSORY-BOARDS - NXP's MX8_DSI_OLED1]
display on the i.MX8 platform on Genode. The panel features an OLED display as
well as a Synaptics RMI4 compliant touch screen.
Genode's i.MX8 display driver that we released with version
[https://genode.org/documentation/release-notes/20.02#Display_engine - 20.02]
supported HDMI devices only, whereas the OLED display is connected via
[https://www.mipi.org/specifications/dsi - MIPI DSI] to the SoC. Therefore, we
extended the display driver by the MIPI DSI infrastructure as well as the
actual driver for the OLED display. This endeavor turned out to be a very
rocky one, which we have documented in detail on our
[https://genodians.org/ssumpf/2020-09-30-mipi_touch - Genodians] website.
[image imx8_oled]
The administrative user interface of Sculpt OS responds to touch input.
In order to enable the touch screen device, we implemented a new Genode
component from scratch. The touch screen is connected via an I2C bus to the
SoC where data can be sent to and received from. At the moment, the I2C
implementation is hidden within the driver but as more devices require I2C
access, it will eventually become a standalone component. Interrupts are
delivered via GPIO pins from the touch screen to the SoC, which made it
necessary to enable i.MX8 support within Genode's generic i.MX GPIO driver. We
took this as an opportunity to streamline, cleanup, and make the driver more
robust. Additionally, all driver components now take advantage of the new
platform driver API for ARM that has been introduced with release
[https://genode.org/documentation/release-notes/20.05#New_platform_driver_for_the_ARM_universe - 20.05].
In its current incarnation, the driver for the display management is not able
to switch in between HDMI or MIPI-DSI connected displays dynamically.
Therefore, the display to be used in Sculpt has to be configured in the
framebuffer configuration manually. By default the HDMI connector is used.
Beyond the driver subsystem, there are few components dependent on the actual
hardware, which is why the look & feel of the Sculpt desktop does not actually
differ from the x86 PC version, with the following exceptions:
When you select the network configuration dialog, you'll have no "Wifi" option
because of the missing hardware. However, the "Wired" option allows you to
start the corresponding driver for the i.MX FEC Ethernet device. The second
difference to the Sculpt OS x86 PC variant is the absence of a virtual machine
solution at the moment. Although Genode comprises a mature
virtual-machine-monitor solution for ARM - see
Section [Multicore virtualization on ARM] - it still lacks a reasonable
storage back end. Therefore, we left virtualization out of the picture for
now. Lastly, there is no possibility to use USB block devices, because the
required management component - a driver manager for i.MX8 - does not exist
yet. We plan to bridge these remaining few gaps compared to the x86 version
with the upcoming Genode releases.
To give Sculpt a try on the i.MX8 EVK board, you have to start the well-known
Sculpt run-script as usual, but for the base-hw kernel. For example:
! tool/create_builddir arm_v8a
! cd build/arm_v8a
! make run/sculpt KERNEL=hw BOARD=imx8q_evk
Under the hood, the run script requests a sculpt-<board> specific package from
the depot package system. Currently, _sculpt-pc_ and _sculpt-imx8q_evk_ are
available.
Multicore virtualization on ARM
###############################
The written-from-scratch virtualization solution for Genode on ARMv8 entered the
picture exactly one year ago with
[https://genode.org/documentation/release-notes/19.11#Virtualization_of_64-bit_ARM_platforms - release 19.11].
Since then, a couple of improvements and validations have been incorporated
into it. Support for VirtIO network and console models had been added.
Moreover, it got streamlined with our prior existing ARMv7 hypervisor and
virtual-machine monitor (VMM). But although the architecture of the VMM was
designed from the very beginning with more than one virtual-CPU (VCPU) in
mind, running a VM on multiple cores had not been addressed nor tested.
With this release, we enhance the virtualization support of the base-hw
kernel, acting as the ARM hypervisor, to support multicore virtual machines.
The VMM implementation got extended to start an entrypoint for each VCPU owned
by a VM. The affinities of those entrypoints are configured to distribute over
all physical CPUs available to the VMM. The affinity of an entrypoint that
handles events of a VCPU is automatically used as the affinity of the VCPU
itself. Whenever a VCPU exit needs to be handled, this is delegated to the VMM
entrypoint running on the same CPU. Once the VMM's entrypoint successfully
handled the exit reason, it resumes the VCPU.
Formerly, the control to start or stop a VCPU was implemented by core's VM
service that runs on the first CPU. But that implied that all different VMM
entrypoints running on distinct CPUs would have needed to frequently call
core's service entrypoint on the first CPU, inducing costly cross-CPU
communication. This is amplified by the fact that core's entrypoint uses a
system call to instruct the kernel's internal scheduler of the corresponding
target CPU, which again would potentially target a remote CPU. For simplifying
the implementation and for improving performance, we slightly extended the
VM-session interface to return a kernel-specific capability addressing a VCPU
directly. With this capability, a VMM's entrypoint is able to directly call
the kernel to start or stop a VCPU instead of using the indirection over core.
However, the detail whether the kernel is called directly or not is hidden
behind the VM session client API and transparent to the user.
Base framework and OS-level infrastructure
##########################################
C runtime
=========
We improved the support for aligned memory allocations to fix sporadic memory
leaks, which occurred with our port of the Falkon web browser. One relevant
change is the implementation of the 'posix_memalign()' function, another
change is that the address alignment of anonymous 'mmap()' allocations is now
configurable like follows:
! <config>
! <libc>
! <mmap align_log2="21"/>
! </libc>
! </config>
Standard C++ library
====================
Even though Genode uses C++ as its primary programming language, we do not
rely on or make use of any C++ standard library within the Genode OS
framework. However, since a C++ STL is a vital part of application programming
with C++, we provide one for applications built on top of the base framework;
in particular the GNU C++ STL library (_libstdc++_). It is treated as a
regular 3rd party library and its functionality is extended on demand. This
approach worked well enough to even enable larger C++-based software like Qt5
and Chromium's Blink engine (as part of QtWebEngine) to run on Genode. That
being said, for developers using _libstdc++_ on Genode, it is not immediately
clear, which features are supported and which are not.
Fortunately, _libstdc++_ includes a testsuite that - as the name suggests -
allows for testing the range of functionality of the library on a given
platform. So we turned to it to establish a base line of supported features.
We were particularly interested in how our port behaves when C++17 is
requested. It goes without saying that this only includes the aspects, which
are specifically probed by the testsuite. Rather than adding thorough Genode
support to the testsuite, we opted for providing an
[https://github.com/cnuke/genode-libstdcxx-testsuite/ - environment] that
mimics the common 'unix' target and allows us to execute the testsuite on
the Linux version of Genode via a regular Linux host OS. It uses the Genode
tool chain to compile the tests and spawns a Genode base-linux system to
execute them.
Executing the testsuite was an iterative process because in the beginning, we
encountered many falsely failed tests. On one hand, most of them were due to
the way C++ is applied in Genode or rather how our build system works
internally. For one, _libsupc++_ on Genode is part of the _cxx_ library. This
library in turn is part of _ldso.lib.so_, the dynamic linker that provides
the base API. As the build system uses stub libraries generated from 'symbol'
files containing the ABI of a given shared object, each missing symbol must
be made available. Otherwise the linking step is going to fail complaining
about undefined references because components use these stub libraries
during compilation. On the other hand, we had to get cozy with the testsuite's
underlying test framework in order to get our test environment straight.
In case of the testsuite, there were a lot of symbols missing because we did
not encounter them so far in our workloads, and thus, were not part of the
symbols file. After all, templates will always generate specific symbols that
are difficult to foresee. Besides that, we lacked support for aligned 'new'
and 'delete' operators. With these adaptions in place, we were able to
successfully execute the testsuite.
In the end, the results paint a good picture. The current short-comings boil
down to
* Support for the *stdc++fs* library is not available as the library is
not ported yet.
* Proper *locale* support in the 'libc' as well as 'stdc++' is not available.
* Support for parallel operations with *openmp* is not available.
* Various subsystems ('std::thread', 'std::random_device', numerics library)
need further attention for proper functionality. This is most prominent
for the failing execution tests where sometimes the threads appear to
get stuck.
These findings are documented at issue
[https://github.com/genodelabs/genode/issues/3925 - 3925].
Consistent Block Encrypter (CBE)
================================
The CBE is a library for the management of encrypted block-devices that is
entirely written in SPARK. It was first announced and integrated with
[https://genode.org/documentation/release-notes/19.11#Preliminary_block-device_encrypter - Genode 19.11],
reached feature-completeness with
[https://genode.org/documentation/release-notes/20.05#Feature-completeness_of_the_consistent_block_encrypter - Genode 20.05],
and has received a highly modular back-end system with version
[https://genode.org/documentation/release-notes/20.08#Consistent_Block_Encrypter - 20.08].
For this release, we thoroughly streamlined the CBE repository, added enhanced
automated quality assurance, and switched to another default encryption
back end.
Repository restructuring
------------------------
Generally speaking, the [https://github.com/m-stein/cbe - CBE repository] has
been freed from everything that is not either part of the SPARK-based core
logic (cbe, cbe_common, and the hashing algorithm), the essential SPARK-based
tooling (initialization, checking), or the Ada-based C++ bindings (*_cxx
libraries). The whole Genode-specific integration, testing, and packaging
moved to Genode's 'gems' repository and the former Genode sub-repository 'cbe'
was replaced by the new CBE port _gems/ports/cbe.port_. We also took the
opportunity to remove many unused remnants of earlier development stages and
to drastically simplify the ecosystem of CBE-related packages.
We hope that this allows for certain characteristics of the CBE project, like
its strong OS-independence or a completely "flow-mode"-provable core logic to
become more clear, while at the same time, the Genode-specific accessories can
benefit from being part of Genode's mainline development.
Automated testing, benchmarking, and proving
--------------------------------------------
The CBE tester is a scriptable environment meant for testing all aspects of
the CBE library and its basic tooling. Through its XML command interface, one
can not only access and validate data of CBE devices but also initialize them,
check their consistency, analyze their meta data, execute performance
benchmarks, manage device snapshots, perform online re-keying or online
re-dimensioning of devices, and, last but not least, manage the required Trust
Anchors.
Before this release, the CBE tester was a mere patchwork solution and many of
the above mentioned features were limited or even missing. For instance block
access was issued only in a synchronous fashion, the Trust-Anchor was managed
implicitly, and validating read data wasn't possible. Besides adding the
missing features, we also reworked the component entirely to follow a clean
and comprehensible implementation concept. The new CBE tester comes together
with the run script _gems/run/cbe_tester.run_ that shall serve as both a
demonstration how to use the tester and an extensive automated test and
benchmark for the CBE.
Furthermore, we created the CBE-specific autopilot tool _tool/cbe_autopilot_
that is meant to establish a common reference for the quality of CBE releases
as well as for their integration in Genode. Running the tool without arguments
will give instructions how to use it. In a nutshell, when running
'tool/cbe_autopilot basics', the tool will GNAT-prove what is expected to be
provable, run all CBE-related run scripts expected to work, and build all
CBE-related packages (existing build and depot directories are not touched in
this process). The idea is to make the successful execution of the test
mandatory before advancing the master branch of the CBE repository or
releasing a new version of the integration in Genode. A handy side-feature of
the tool is that one can run 'tool/cbe_autopilot prove' to do only the
GNAT-proving part. With 'tool/cbe_autopilot clean' finally, the tool cleans up
all of its artifacts.
Libcrypto back end for block encryption
---------------------------------------
The introduction of VFS plugins for CBE back ends in the previous Genode
release made it much easier to interchange concrete implementations. This
motivated us to play around a bit in our endeavour of optimizing execution
time. It turned out that especially the choice of the block-encryption back
end has a significant impact on the overall performance of CBE block
operations. It furthermore seemed that especially the 'libsparkcrypto'
library, our former default for block encryption, prioritizes other qualities
over performance.
That said, in general, we want to enable an informed user to decide for him-
or herself which qualities one prefers in such an algorithm. The VFS plugin
mechanism pays tribute to this. And it also seems very natural to us to
combine a SPARK-based block-device management with a SPARK-based encryption
back-end like 'libsparkcrypto'. But for our default use case, we came to the
conclusion that the 'libcrypto' library might be a better choice.
Streamlined ioctl handling in the C runtime / VFS
=================================================
The Genode release
[https://genode.org/documentation/release-notes/19.11#C_runtime_with_improved_POSIX_compatibility - 19.11]
introduced the emulation of ioctl operations via pseudo files. This feature
was first used by the Terminal. With the current release, we further employ
this mechanism for additional ioctl operations, like the block-device related
I/O controls, as the long-term plan is to remove the notion of ioctl's from
the 'Vfs::File_io_services' API all-together.
We therefore equipped the block VFS-plugin with a compound directory hosting
the pseudo files for triggering device operations:
:info: This file contains the device information structured as 'block'
XML node having 'size' and 'count' attributes providing the used block size
as well as the total number of blocks.
:block_count: contains the total number of blocks.
:block_size: contains the size of one block in bytes.
Furthermore, we split the existing 'ioctl' handling method in the libc into
specific ones for dealing with terminals and block devices because at some
point more different groups of I/O controls are to follow.
The first one to follow is the 'SNDCTL' group. This group deals with audio
devices and corresponds to the standard set by the OpenSoundSystem (OSS)
specification years ago. In the same vein as the terminal and block I/O
controls, the sound controls are implemented via property files.
The controls currently implemented are the ones used by the OSS-output plugin
of [https://cmus.github.io/ - cmus], the driving factor behind the
implementation, which uses the (obsolete) version 3 API.
At the moment, it is not possible to set or rather change any parameters. In
case the requested setting differs from the parameters of the underlying
audio-out session - in contrast to the suggestion in the OSS manual - we do
not silently adjust the parameters returned to the callee but let the I/O
control operation fail.
The following list contains the currently handled SNDCTL I/O controls:
:SNDCTL_DSP_CHANNELS: sets the number of channels. We return the available
channels here and return ENOTSUP if it differs from the requested number of
channels.
:SNDCTL_DSP_GETOSPACE: returns the amount of playback data that can be written
without blocking. For now it amounts the space left in the stream buffer of
the audio-out session.
:SNDCTL_DSP_POST: forces playback to start. We do nothing and return success.
:SNDCTL_DSP_RESET: is supposed to reset the device when it is active before
any parameters are changed. We do nothing and return success.
:SNDCTL_DSP_SAMPLESIZE: sets the sample size. We return the sample size of the
underlying audio-out session and return ENOTSUP if it differs from the
requested format.
:SNDCTL_DSP_SETFRAGMENT: sets the buffer size hint. We ignore the hint and
return success.
:SNDCTL_DSP_SPEED: sets the sample rate. For now, we always return the rate of
the underlying audio out session and return ENOTSUP if it differs from the
requested one.
The libc extension is accompanied by an OSS VFS plugin that gives access to an
audio-out session by roughly implementing an OSS pseudo-device. It merely
wraps the session and does not provide any form of resampling or re-coding of
the audio stream.
[image cmus]
Image [cmus] depicts how the various pieces work together in a real-world
scenario. The interplay of the extended libc with the OSS VFS plugin allows
for listening to MP3s - for the time being the format is restricted to
44.1kHz/16bit - on Sculpt using the [https://cmus.github.io/ - cmus]
audio player.
The current state serves as a starting point for further implementing the OSS
API to cover more use cases, especially with ported POSIX software like
VirtualBox and Qt5 or even as SDL2 audio back end. While showing its age, OSS
is still supported by the majority of middle ware and makes for a decent
experimentation target.
Device drivers
##############
VirtIO support
==============
Thanks to the remarkable contribution by Piotr Tworek, the Genode OS framework
has become able to drive VirtIO network devices.
He did not only provide a single VirtIO network driver but a framework to
easily add more VirtIO driver classes in the future. Either the devices are
connected as PCI devices or directly as platform devices with fixed
memory-mapped I/O addresses. The framework supports both and abstracts away
from the concrete connection type.
The VirtIO network driver enables networking for Genode when using the
'virt_qemu' board on either the ARMv7a or ARMv8a architecture. However, the
VirtIO device configuration on Qemu is dynamic. The order and presence of
different command line switches affect the bus address and interrupt
assignment of each device. To make the use of Genode with Qemu robust in
changing environments, a tiny helper component was supplemented. This
component named 'virtdev_rom' probes the memory-mapped I/O areas of the system
bus and detects available and known VirtIO devices. The results are provided
in the form of a configuration that can be consumed by the platform driver to
assign the correct device resources to the corresponding VirtIO driver.
The VirtIO network driver in action, as well as the interplay of the platform
driver and the 'virtdev_rom' component can be observed when using the
'drivers_nic-virt_qemu' package.
Improved support for OpenBSD audio drivers
==========================================
So far, the supported drivers exclusively used PCI as transport bus and for
practical reasons, the emulation environment was tied to it. The bus handling
has now moved into its own compilation unit to make future addition of drivers
that employ other transport buses easier. On the same account, the component
got renamed to 'pci_audio_drv' to reflect its bus connection.
While at it, the execution flow of the component got adapted. The kernel code
should have been executed within the context of the main task like it is done
in the DDE Linux drivers. The initial port of the HDA driver, however, called
the code directly from within the session as there was no immediate reason to
use a task context because suspending the execution was not needed. When using
USB devices, that is no longer possible as we have to suspend the execution
during the execution of the kernel code. So we pass in the audio data and
schedule the emulated BSD kernel code.
The above mentioned changes are mostly preliminary clean-up work for the
upcoming support of USB audio devices.
Furthermore, we implemented timeout handling in the driver and use Genode's
timeout framework API to schedule timeouts and for providing the current time.
For now there is only one timeout - the unsolicited Azalia codec event - and
therefore the timeout queue consists of solely one timeout object. Those
events are important for detecting plugged in headphones.
Supporting headphones was further refined by accounting for the situation
where the driver is started while headphones are already plugged in and the
mixer needs to be configured accordingly. In particular, on the Fujitsu S938
the driver lacked the proper quirk for switching between the internal and
external microphone.
In addition to the changes made to the audio driver component, the behaviour
of the audio mixer was adjusted with regard to handling the configuration
of a new session. The mixer now applies the settings already stored in its
configuration to new sessions instead of only reporting them. In case of
Sculpt, where an existing launcher already contains a valid configuration,
that allows for setting the volume levels appropriately for known sessions
prior to establishing the connection.
Retiring the monolithic USB driver
==================================
With [https://genode.org/documentation/release-notes/18.08#Decomposed_USB_stack - release 18.08],
a componentized USB stack got introduced next to our time-tested monolithic
USB driver. With the current release, the driver manager as used by Sculpt OS
switched to use the new USB stack in order to benefit from the de-composition
and from more supported USB devices. The monolithic driver was still based on
an older DDE-Linux revision compared to the componentized version. This step
paves the ground to retire the monolithic USB driver with the next Genode
release and will improve the number of supported USB devices with the upcoming
Sculpt OS release.
Platforms
#########
Hardware P-State support on PC hardware
=======================================
Intel CPUs feature Speed Shift respectively Hardware P-State (HWP)
functionality in order to balance CPU frequency and voltage for performance
and power efficiency. Up to now, the UEFI firmware of the notebooks we worked
with selected or made an option selectable in the UEFI configuration to
specify the desired behaviour, e.g. optimize for performance or power
efficiency.
With a recent Lenovo notebook, however, we faced the issue that either the fan
would run for too long after some load and/or the performance of the CPUs
regressed. Finding a well working sweet spot
[https://github.com/genodelabs/genode/issues/3871 - seems hard].
This experience prompted us to investigate how the Intel HWP feature can be
set and configured. After some experiments, we achieved to reduce the fan
noise and received better performance by tweaking the Intel HWP settings.
However, changing the Intel HWP settings requires access to the privileged
mode on all available CPUs. Since Genode supports several kernels, a solution
would require us to modify all kernels or the feature would remain solely
available to one kernel. We went for a different approach.
On x86, we use the tools from the
[https://genode.org/documentation/release-notes/18.08#New_Intel_Microcode_update_mechanism - Morbo project],
e.g., bender and microcode, to run code before the kernels are booted. The
jobs of the tools are to scan, enable, or apply changes to the CPUs and
chipset, which are not required to change during runtime. We came to the
conclusion that the named bootstrap tools are good places to apply such
one-time Intel HWP settings for the moment.
During the course of adding the Intel HWP functionality, we merged the
microcode functionality into the bender tool and made it configurable via the
boot options 'microcode' and 'intel_hwp'. A typical generated grub2
configuration by using both options would look like this:
| insmod multiboot2
| insmod gzio
| multiboot2 /boot/bender bender microcode intel_hwp
| module2 /boot/micro.code micro.code
| module2 /boot/hypervisor hypervisor ...
| module2 /boot/image.elf.gz image.elf ...
When using the NOVA kernel and Genode's _run_ tool for booting respectively
disk-image creation, one may use the existing 'options_bender' variable in
_tool/run/boot/nova_. The microcode option is added by setting the
'apply_microcode' flag in the same file. The 'intel_hwp' option, at the other
hand, can simply be appended to 'options_bender'. On startup, bender will print
the applied HWP settings for each core to the serial output if the
'intel_hwp' option was set. The new feature will try to set Intel HWP to
'PERFORMANCE' mode, the mode for which we observed the best results.
NOVA microhypervisor
====================
The IO-MMU is a hardware feature to protect operating systems, e.g., Genode,
against misbehaving devices and/or corresponding device drivers. The feature
is supported on x86 since the
[https://genode.org/documentation/release-notes/13.02#DMA_protection_via_IOMMU - 13.02 release]
and described in the release notes. Up to now, this feature is solely
supported for Intel hardware, in particular CPUs and chipsets supporting Intel
VT-d.
With the current release, we add support for AMD's IO-MMU variant to the
Genode framework for the NOVA kernel - being the first one out of the
supported microkernels. Being conceptionally equivalent, the actual
implementation for AMD differs from Intel unsurprisingly. In order to add the
support, a new IO-MMU interface abstraction for accommodating both versions -
Intel and AMD - has been added to the NOVA kernel. Further, the discovery of
the available AMD IO-MMUs required the traversal of different ACPI tables than
for Intel and another page table format for the IO-MMU had to be added. On the
Genode framework side, only very few changes were necessary, namely the
detection of the IO-MMU feature by parsing the ACPI tables in Genode's ACPI
driver as well as the ported Intel ACPICA component.
The change has been already successfully tested on various Ryzen desktops and
notebooks on a backported Sculpt 20.08 branch.

=============================================
How to use Genode with the Fiasco microkernel
=============================================
Norman Feske, Christian Helmuth
Abstract
########
This documentation describes the process of building and booting the L4/Fiasco
version of Genode. It assumes that you are familiar with basic concepts
described in the introductory documentation of Genode, namely the "How to start
exploring Genode" document.
Preconditions
#############
The Fiasco version of Genode relies on the following components from
the source tree of the Fiasco microkernel and the L4 environment (which also
need additional tools).
Tools
=====
* Gawk
* Bison
* Byacc
* Python
The Fiasco microkernel
======================
Information about Fiasco are provided at its official website:
! http://os.inf.tu-dresden.de/fiasco/prev/
To download the kernel and integrate it with Genode, issue the following
command from within the toplevel directory:
! ./tool/ports/prepare_port fiasco
For the vesa driver on x86 the x86emu library is required and can be downloaded
and prepared by invoking the following command:
! ./tool/ports/prepare_port x86emu
This command will download a prepackaged version of the kernel tested
with Genode. The build process of the kernel is integrated with Genode's
build system. After creating a build directory using 'create_builddir'
with 'fiasco_x86' as argument:
! <genode-dir>/tool/create_builddir fiasco_x86 \
! BUILD_DIR=<build-dir>
From within the new <build-dir>, the kernel can be compiled via
! make kernel/fiasco
When using Genode's run mechanism, there is no need to explicitly build the
kernel. The run environment (see 'tool/run/boot_dir/fiasco') takes care of it.
So you can simple execute run scripts from within the build directory, for
example:
! make run/demo
Behind the scenes
=================
For using the L4/Fiasco kernel, some basic user-level components and libraries
are needed. These are subsumed under the name L4 environment an are organized
as a number of packages. These packages provide two types of components. There
are low-level components for booting up and interfacing to Fiasco and there are
higher-level components that compose a basic OS infrastructure. For Genode, we
only rely on the low-level packages.
Previous versions of Genode included all necessary sources from the L4
environment in the '3rd/fiasco/snapshot' subdirectory. From release 10.02, the
'3rd' directory is no longer part of the release archive and also removed from
the subversion repository. Please download the '3rd_fiasco.tar.bz2' archive.
The source are organized as follows
:'tool': contains the tools that are used by the build processes of
the L4 environment and Fiasco. For example, the build process of Fiasco
relies on the 'preprocess' tool.
:'kernel': contains the Fiasco microkernel.
:'l4': contains the L4-environment source tree. The single packages
are located at 'l4/pkg'.
From all the packages of the L4 environment, the following three are of
interest for using Genode:
:'pkg/l4sys': contains the Fiasco system-call bindings.
The system-call bindings are a set of C-header files that define the
application-programming interface for invoking the system calls of
Fiasco.
:'pkg/sigma0':
Sigma0 is the initial memory manager required to use Fiasco.
:'pkg/bootstrap':
Bootstrap is the program that is started by the boot loader.
After being started, Bootstrap prepares the bare machine to
accommodate Fiasco. On many embedded architectures, bootstrap
is used to create a single binary image containing all boot-time
OS components.
Those components are implicitly built by the Genode build system when
issuing 'make kernel/fiasco'.

===================================
Genode on the Fiasco.OC microkernel
===================================
Stefan Kalkowski
Fiasco.OC is a microkernel originally developed by the OS group of the
TU-Dresden. Nowadays, it is primarily maintained and developed by
the company Kernkonzept. It's an object-oriented capability-based system
for x86, ARM, PowerPC and MIPS platforms.
This document provides brief instructions about downloading, building and
booting the Fiasco.OC version of Genode.
Prerequisites
#############
You need certain tools to use the Fiasco.OC build system. On Debian/Ubuntu
systems you have to install the following packages:
! apt-get install make gawk g++ binutils pkg-config g++-multilib subversion
Moreover, you need to download and install the tool-chain used by Genode. Have
a look at this page:
:[http://genode.org/download/tool-chain]:
Genode tool-chain
Building the Fiasco.OC version of Genode
########################################
The current version of Genode is available at the public Github repository:
:http://github.com/genodelabs/genode:
Github repository of Genode
After you've fetched the Genode source tree from the git repository, or
downloaded the latest release tar archive, you need the Fiasco.OC source code,
its kernel-bindings, additional bootstrap tools etc. To simplify that step,
you can use the 'prepare_port' tool:
! ./tool/ports/prepare_port foc
This will install all necessary third-party source code in the 'contrib' folder.
Now, go to a directory where you want the Genode/Fiasco.OC build directory to
remain. Use the helper script in the 'tool' directory of the Genode
source tree to create the initial build environment. You need to state the
build directory you want to create, and the hardware architecture to run
Fiasco.OC/Genode on. Choose 'x86_32', 'x86_64', or one of the available ARM
boards.
! <genode-dir>/tool/create_builddir x86_64
Now, go to the newly created build directory and type make:
! cd build/x86_64
! make KERNEL=foc
This will build the Fiasco.OC kernel, its bootstrap code, and every Genode component,
that runs on top of Fiasco.OC.
If you just want to give Genode/Fiasco.OC a try, you can call e.g.: the demo run-script
instead of building everything:
! make run/demo KERNEL=foc
