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

# This library is for avoiding clashes between Linux and Genode includes.
|
|
# If we were to compile all the *.c files of this library directly with the
|
|
# Wireguard target there would be only one INC_DIR applied to *.cc files as
|
|
# well as to *.c files. Some Genode headers, however (e.g. 'net/udp.h' or
|
|
# 'net/dhcp.h') exist with the same include identifier in both Linux and
|
|
# Genode, and we would have the problem that we want the Linux variant in *.c
|
|
# files and the Genode variant in *.cc files. Therefore, we create two
|
|
# dedicated INC_DIR settings (that of the library and that of the target).
