0359ee6a76 sandbox: fix position scaling in affinity filter
During position scaling use the location width/height which is the permitted
dimension within the child space, instead of using the whole possible
child space. (Fixup for "init: scale affinity location" Issue #1412)

Thanks to the report by Peter.

a0fb944721 Propagate session diag flag to core
This commit restores the diag feature for selecting diagnostic output of
services provided by core. This feature became unavailable with commit
"base: remove dependency from deprecated APIs", which hard-wired the
diag flag for core services to false.

To control this feature, three possible policies can be expressed in a
routing target of init's configuration:

* Forcing silence by specifying 'diag="no"'
* Enabling diagnostics by specifying 'diag="yes"'
* Forwarding the preference of the client by omitting the 'diag'
  attribute

b097e598f1 usb_hid: use heap instead of dma/mem allocator
The usb_hid driver does not need to distinguish between
normal memory and DMA capable memory, since all requests are routed via the
USB raw session to the usb host driver. The default Malloc implementation
implements this distinction, however exposes restrictions on the size of
allocations. As seen now by several USB HID devices, the size of device
driver allocations depend on read out hardware features and can be
larger than we support with our specialized default Malloc implementation.

Since we don't need this functionality, switching to an well
tested allocator (Heap) which can cope with varying sizes of allocation,
we can mitigate the size restriction.

  multiple DHCP option 6 entries from DHCP replies that it received as DHCP
  client
* A DHCP server at the NIC router can now be configured statically with
  multiple DNS server addresses to propagate
* The 'dns_server_from' attribute of the DHCP server of the NIC router now
  supports the forwarding of multiple DNS server addresses
* The automated run/nic_router_dhcp test tests all the above mentioned new
  functionality and reconfiguring it at runtime. The test was added to the
  autopilot.
* All run scripts were adapted to fit the new NIC router configuration
  interface

8d8edaea5d nic_router: fix link state on dhcp server reconfig
When reconfiguring the NIC router modifies the information that DHCP clients
received through a DHCP server of the NIC router, the link state of the
correspodning interface has to do a "down-up" sequence. This provides a signal
to the DHCP clients to redo DHCP, receive the new information and update
accordingly.

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.

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'

repos/os/include/os/sandbox.h. Since the code refers to ::Sandbox::Child
and its already in ::Sandbox namespace we can just drop "Sandbox" and
refer to just Child, which makes clang happy.

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.

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.
