0ffc55a20a Remove unneeded session_size check
As accommodating the session component object is already taken care of
be the root component implementation, remove the remaining redundant
checks.

9d383037e4 lx_emul: set task 'stack' member
Instead of allocating the stack via 'kmalloc' point it to the actual
stack used by the task. This addresses issues with the USB
host-controller driver where sometimes hub port enumeration is not
working.

Fixes #4522.

9375e8d010 wireguard: no warning about possible alignm. issue
We locally disable 'address-of-packed-member' warnings because GCC complained
about possible alignment issues when returning a reference to a packed member
as naturally aligned pointer (for some reason only on arm_v8a). We know that
the member is aligned to NETDEV_ALIGN via __attribute__ and that the warning
is therefor unnecessary.

48e396913c wireguard: don't always rebuild device.c/netlink.c
We have to correct the CC_OPT_* variable for these files and used to do so via
phony pre-requisite for the corresponding object files because the correction
had to take place after the variable initialization in
import-lx_emul_common.inc and before the creation of the object files. However,
this caused the objects to always rebuild.

This commit fixes this issue by using Make's feature of target-specific
variables instead. The drawback of this solution is that we can no longer
override CC_OPT_* with a modification of its original value but instead have to
override with a completely new value. This is because otherwise, Make would
either complain about recursive assignment or produce an empty value.

b1c77dc42b wireguard: enable WARN_STRICT_CONVERSION in lib
The strict conversion warnings were disabled during development when the
contrib code was still compiled with the wireguard lib. Now this isn't

36d2374ff9 wireguard: exit on invalid configurations
With this commit, the WireGuard component exits with a descriptive uncaught
exception on invalid configurations or when the user attempts to re-configure
attributes that are not re-configurable (private_key, listen_port, interface).

This is particularly important when it comes to the not re-configurable private
key. If the component would just ignore the attempt to override the private
key, the user may come to believe that his old (potentially compromised)
private key is not in use anymore.

The fact that the component now exits instead shouldn't be a problem, as the
user would have to restart the component anyway in order to apply the new
attribute values.

The commit also extends the wg_reconfig run script to test that WireGuard
exits on the attempt to re-configure the private key.

560a166613 wireguard: flags value via enum when adding a peer
I used to set the peer flags to 2 when adding a peer but merely because I
observed that value in my reference Linux. I now found that the flag 1<<1 means
'WGPEER_F_REPLACE_ALLOWEDIPS' and is ignored whenever the peer is new. Anyway,
I keep setting the flag but with the clearer enum name because the wg tool is
doing it as well when adding new peers and we want to stay close to how the
original code interacts.

Introduce an arch-specific wireguard lib that contains all code from the

83408ef35c wireguard: rename wireguard lib
The wireguard library's purpose is having a separate INC_DIR setting for the
files that need Linux include paths that would clash with Genode include paths.
Therefore, the name wireguard_lx_inc_dirs is more descriptive. Furthermore,
this allows us to create a new arch-specific wireguard lib in a future commit
in the course of preventing arch-specific target.mk's (a commonly used
approach in Genode).

03349f9fff lx_emul/random: re-seed the local PRNG regularly
With this commit, the Xoroshiro128+ PRNG in lx_emul/random.cc gets wrapped
by a new class that automatically re-seeds the PRNG with jitterentropy every
1024 * 1024 + random(0..4095) bytes of generated output.

ab0bce77ec lx_emul & wireguard & wifi: centralized random.cc
Both the Wifi driver and the WireGuard port used local implementations for
their source of randomness. Wifi used a Xoroshiro128+ PRNG for rapid generation
of random values but initialized this PRNG always with the same static seed
value. WireGuard, in contrast, requested each random byte directly from the
jitterentropy lib, which is considered to be very time intensive.

This commit removes the local variants of random.cc and introduces a new
centralized lx_emul/random.cc . The new variant combines the former approaches,
so, that jitterentropy is accessed only in order to generate a random seed for
a Xoroshiro128+ PRNG. Front-end requests for random values are then fulfilled
efficiently via the PRNG.

:Warning:

The output of the Xoroshiro128+ PRNG that is used in the new implementation of
the lx_emul randomness functions has known statistical problems (see
https://en.wikipedia.org/wiki/Xoroshiro128%2B#Statistical_Quality).
Furthermore, the integration of Xoroshir128+ with the lx_emul code was not
reviewed/audited for its security-related properties, so far, and has the
known deficiency of seeding the PRNG only once during initialization. Thus,
we strongly advise against the use of the lx_emul randomness functions for
security-critical purposes.

a845dffa63 dde_linux: port of WireGuard kernel module
A userland component that ports the Linux WireGuard kernel module (originally
from kernel version 5.14.21) and integrates it via a NIC session (public
network side) and an Uplink session (private network side). The
WireGuard-specific device configuration is done through the component
configuration. The port is done using lx_emul, lx_kit and the virt_linux
targets. The commit adds also 4 corresponding run scripts of which 3 are fully
automated of which 1 is added to the autopilot.

:Warning:

Although in principal functioning, the WireGuard port has not been exposed to a
sufficient amount of real-world testing, so far. Therefore, we strongly
recommend not to use it in any security-critical scenarios! There is no
guarantee that the port meets any of the security goals pursued by the
WireGuard protocol or other WireGuard implementations!

cded594346 lx_emul & arm: define ZERO_PAGE
The implementation was copied from the already existing LX-emul implementation
for x86 but the commit additionally page-aligns the array that serves as
backing store for the zero page as we assume this to be expected by the contrib
code. However, this commit doesn't apply the alignment also to the x86
implementation as we agreed, that this should be done in a separate commit.

9713014130 dde_linux: add virt_linux lx_emul flavor
To support device-less protocol-stacks only ports, we can use a
Virt I/O Linux kernel flavor, and export the lx_kit/lx_emul parts
not depending on platform API and devices.

* Moreover the device-dependent lx_emul parts get removed
  from the common lx_emul import rules

3966d6f16f usb_host_drv: move it to legacy_usb_host_drv
To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and
consistently name the old drivers with a legacy_ prefix.

2515196b82 lx_kit: add Platform session wrapper for x86
The x86 platform driver uses a different API than the one for ARM for
which the lx_kit glue code was designed. Since the x86 platform driver
will eventually adopt a similar interface we implement a wrapper that
encapsulates the old interface.
