- Move C++ sources from lib/wireguard to app/wireguard, which require
Genode include paths (that conflict with linux)
- Rename lib/wireguard_lx_inc_dirs to lib/wireguard, which builds linux
sources with linux include paths
The IP stack checks "user" pointer access, for example, for iov's using
'access_ok' which in turn calls '__access_ok'. The function checks if the
pointer is below TASK_SIZE_MAX, which is usually a big value on 64 bit
systems, but 3GB on 32 bit systems. Because the IP stack is mostly used with
Genode's libc, where pointers on some kernels (base-linux) can be >3GB and we
don't want to make an additional copy of each buffer/iov interacting with the
IP stack, we short circuit the function
issue #5165
This commit updates lxip from version 4.4.3 to 6.1.20. It uses the
current lx_kit approach and is a shared library again. The stack has
been tested for x86_32/x86_64/arm_v6/arm_v7/arm_8.
The C-interface of the IP stack can be found under
lxip/include/genode_c_api/socket.h.
issue #5104
The bulk of the driver code now lives in the 'dde_linux' repository,
which is available on all platforms, from where it can be referenced by
other repositories.
The 'wifi_drv' binary was delegated to a generic harness that includes
all configuration and management functionality shared by all wireless
device driver components, e.g., the wpa_supplicant. The code of the
device driver emulation environment is located in 'src/lib/wifi'. It
is referenced by the platform-specific driver library that resides in
the corresponding platform repository. The runtime configuration needs
to point the driver to proper driver library.
The platform-specific library is in charge of orchestrating the contrib
source utilized by the driver as well as providing the 'source.list'
and 'dep.list' files. It must include the generic library snippet
'repos/dde_linux/lib/wifi.inc' that deals with managing the emulation
environment code.
The 'repos/dde_linux/src/drivers/wifi/README' file contains more
detailed information on how to deploy the driver.
Issue #4861.
This commit introduces support for building the WLAN driver for ARM
platforms. It makes the WPA supplicant and its support libraries
available for all platforms. It also seperates the PCI parts to
accommodate platforms where other bus protocols are used.

Introduce an arch-specific wireguard lib that contains all code from the
former arch-specific target.mk files. This allows us to create a generic
target.mk that merely depends on the library and a dummy.cc file. The latter
ensures that building/linking of the target isn't skipped by the build system.
Ref #4519
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).
Ref #4519
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!
Ref #4397
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.
Ref #4397
We use the architecture-specific setjmp/longjmp implementation without
modification in the newer lx_kit implementation as well. There is no
need for a duplication.

* Make package buildable for ARM too
* Move usb library to src targets for explicitly named targets
* adapt remaining run-scripts to use the correctly named usb drivers
Ref #2190
According to the creator of the net-stat lib, this lib was a mere debugging
tool that is not used anymore nor worth the work of updating the it to
modern Genode coding paradigms. Also, there exist no tests for the lib.
This is a follow-up commit to "Increase default warning level", which
overrides Genode's new default warning level for targets contained in
higher-level repositories. By explicitly whitelisting all those targets,
we can selectively adjust them to the new strictness over time - by
looking out for 'CC_CXX_WARN_STRICT' in the target description files.
Issue #465
A binary file may be a temporary Vim .swp file when examining contrib
sources. The commit prevents build errors like
.../repos/dde_linux/lib/mk/lxip_include.mk:29:
target '.../x86_64/var/libcache/lxip_include/include/include/include/Binary'
given more than once in the same rule
.../repos/dde_linux/lib/mk/lxip_include.mk:29:
target '.../x86_64/var/libcache/lxip_include/include/include/include/file'
given more than once in the same rule

Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
