The driver is superseded by the USB network driver (usb_net) which also
contains MBIM support for LTE modems previously provided by this
driver.
issue #4958
Since the wireless LAN driver is actually a 'Libc::Component' due to
its incorporation of the 'wpa_spplicant' application, we have to
intercept its construction because we have to initialize the Lx_kit
environment before any static ctors are executed. Most Linux initcalls
are implemented as ctors that will be otherwise implicitly executed
before the controll is given to us in 'Libc::Component::construct'.

This commit introduces preliminary support for joining networks secured
via WPA3-personal. So far it was only tested with the one OpenWRT AP
configured for WPA3 (see excerpt below) where it WPA3-only as well as
WPA2/WPA3 mixed worked fine.

Issue #4861.
The supplicant is updated to the current release and is now downloaded
as archive rather than pulled from git. For the time being 'libnl' is
still kept at 3.2.25 as the current 3.7.0 release relies on more Linux
infrastructure that our integration does not provide.
Issue #4861.
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.

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.
Ref #4519
The strict conversion warnings were disabled during development when the
contrib code was still compiled with the wireguard lib. Now this isn't
necessary anymore as the contrib code is in the wireguard_lx_inc_dirs lib.
Ref #4520
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
.SHELLFLAGS is extended by option pipefail to make pipes fail if any pipe
element fails. As .SHELLFLAGS is exported into sub-make instances it
must be unexported before calling third-party build systems recursively.
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.

In order to perform a smooth transition from NIC drivers that act only as NIC
session clients to NIC drivers that act only as Uplink session clients, this
commit introduces an intermediate state in which all NIC drivers support both
modes. That said, a NIC drivers mode is now statically determined through a new
optional 'mode' attribute in the drivers <config> tag that can be set to either
'nic_server' (default value) or 'uplink_client'. Reconfiguring this attribute
at a driver doesn't have any effects. Whithout this attribute being set, all
NIC drivers will behave the same as they did before the commit. When set to
'uplink_client', however, instead of providing a Nic service, they request
an Uplink session whenever their network interface becomes "UP" and close the
session whenever their network interface becomes "DOWN".
Ref #3961
Thise driver supports USB LTE modems for Huawais' ME906s through MBIM
and provides a traditional Nic session. The "control" interface is a
Terminal session, which can be used via libmbim/mbimcli.
issue #3822
By now, the enumeration of peripheral interrupts on Raspberry Pi 1 was
different in between base-hw kernel and Fiasco.OC. Therefore, hacks were
needed in every driver to request the correct interrupt number dependent
on the kernel. Before reproducing the same in the platform driver for rpi,
we can more easily use the same enumeration with base-hw.
