596c20c199 pc: enable SMP and softirq/tasklets in lx_emul
Enables symetric-multi-processor support in the Linux kernel configuration
used as base for the driver ports for PC. This is done to be compliant with
common usage of x86 drivers today.
Moreover, this commit uses the original kernel source for softirq/tasklet
implementation to get rid of the insufficient shadow implementation
in the lx_emul sources.

757fdba9fd dde_linux: set max timeout for rcu_needs_cpu
Adhere to include/linux/rcutiny.h behaviour, which sets the max timeout
for rcu_needs_cpu. Without the commit, in the most cases the timeout value
is zero (or random since the pointer is on stack uninitialized), which leads
to programming very short timeouts again and again, making the system never
idle.

d5b1d9466a nic_router: clear ARP cache when domain is down
Whenever a domain looses all its interfaces or the link state of all attached
interfaces is down at once, the domain potentially moves to another Ethernet
segment and should therefore consider its ARP cache to be outdated.

RFC 826 states that "... If a host moves, any connections initiated by that
host will work, assuming its own address resolution table is cleared when it
moves. ...".

Therefore, this commit introduces clearing the ARP cache and the initially
stated events.

This commit was motivated by an issue with the PinePhone Modem and USB NIC.
On the PinePhone, the Modem has its own OS and acts as direct gateway to the
outer world for the USB NIC that is driven by Genode. However, whenever the
Modem gets restarted, Modem and USB NIC receive a new MAC address. This used
to conflict with the NIC routers ARP entry for the Modem that didn't cease to
be valid.

With this commit, the integrator of such a scenario at least has a convenient
way of fixing this by ensuring that all interfaces at the USB NIC domain go
down when resetting (e.g. by ensuring that the USB NIC is the only interface at
that domain).

925d229d67 nic_router: find AVL string nodes w/o exceptions
Replaces the former use of the 'find_by_name' method of the AVL string tree.
This method returned a reference to the found object and threw an exception if
no matching object was found.

The locally implemented replacement doesn't return anything and doesn't throw
exceptions. It takes two lambda arguments instead. One for handling the case
that a match was found with a reference to the matching object as argument and
another for handling the case that no object matches.

This way, expensive exception handling can be avoided and object references
stay in a local scope.

Furthermore, this commit modifies the local wrapper for the  insert method of
the AVL string tree, so, that it follows the above mentioned concept as well.

which it is handled.

Attempts to remove the access to the region was not successful, since some
SSDT table contains ACPI AML code which is executed regularly and read/write
the Opregion.

The patch adds support to make a copy of the Intel Opregion and report it as
is. The copy was sufficient to make the Intel display driver working to find
and lookup the Intel VBT (video bios table) information to setup all
connectors on a Fujitsu U7411 docking station.

b1195508ba platform_drv: avoid filtering of dev in ALL policy
ACPICA needs access to the host bridge 0:0.0 on Intel, which is also
accessed by the Intel display driver. Since for the Intel display driver the
PCI device is specified in the policy explicitly, the PCI device is filtered
out for the ACPICA driver which uses the policy "ALL".

f4f2b456b6 base-hw: invalidate VM TLB entries in deletion
This commit introduces a hypervisor calling interface. The host kernel can
use it to either switch to a guest VM, or to invalidate the TLB with
regard to a specified VM id.
The VM-specific TLB invalidation is called whenever a VM (Vcpu)
gets destroyed.

d6592ca2cb base-hw: unset deleted PD values in MMU
When a PD gets deleted check whether it is active on the current CPU resp. MMU.
If yes, switch to core/kernel's PD to prevent that invalid page-tables or
address-space IDs are still in use. Moreover, whenever we switch to an idle
thread, we switch to kernel/core's PD too. Thereby, we prevent that vanished
PDs are still active on CPUs different from the one, where the core entrypoint
is active, which does the PD deletion.
This whole scheme is only valid under the assumption that core has only one
entrypoint running on one CPU.

We locally disable 'address-of-packed-member' warnings because GCC complained
about possible alignment issues when returning a reference to a packed member

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.

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.

With this commit, the Xoroshiro128+ PRNG in lx_emul/random.cc gets wrapped

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.

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.

Although in principal functioning, the WireGuard port has not been exposed to a
sufficient amount of real-world testing, so far. Therefore, we strongly
