df5cadc8ad pc_wifi_drv: only disable failed access-point
The driver wrongfully disabled all APs if it was configured with an
auto-connect list containing multiple APs when one of those was
disabled as a result of using wrong credentials.

This commit changes the way network enable- and disablement are
handled by only operating on the given access-point in question.
It also removes unused code touched by these changes.

Thanks to Peter for bringing this problem to our attention.

Fixes #4517.

c38b71146b trace_buffer: only iterate after initialization
There is a race between the trace subject doing the buffer
initialization and the monitor trying to iterate the buffer entries. If
the monitor tries to iterate entries of an uninitialized buffer, it will
read the very first entry twice. The monitor should therefore only start
iteration when the buffer has been initialised.

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.

1f3b6490f2 nitpicker: update hover state on touch events
The hover state is evaluated for the routing of input events. When
routing a touch event, the decision should be based on the most recently
observed touch position. Without this patch, however, the hover state kept
referring to the initial pointer position (screen center) in the absence
of any other motion events.

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.

bd501404db net: add methods required for WireGuard port
* Adds methods for copying raw data to the data field of Ethernet frames and
  UDP packets. This is used in the port to wrap the higher-layer packet data
  prepared by the contrib code with the additionally required headers before
  sending it at a network session.
* Adds a method to cast raw data to an IPv4 packet. This is required in the
  port in order to check values in stand-alone IP packets produced by the
  contrib code before sending them at a network session.
* Adds methods for setting UDP ports given big endian port values without
  having to convert to little endian in the app and then back to big endian in
  the net lib.

d324331325 pc: centralize initcall header
Instead of each driver providing its own header file use a central
header as the initcall order header should cover _all_ provided
initcalls resulting from the used 'pc_linux' kernel config.

Note that the 'pc_linux' configuration was extended with the
'USB_USBNET' option because the module's initcall is needed for the
Genode C API for USB glue-code and the 'PACKET' option needed by
the wireless lan driver.

The lack of theses options was not noticed as each driver used its
own initcall header so far that stemmed from the initial porting
effort.

de7fdd3e1a platform_drv: wait for device's availability
Instead of returning an invalid device capability when a device
is (not yet) available, e.g. a PCI device is requested before the
PCI bus got parsed accordingly, we check the device capability
within the Platform::Connection utilities, and register temporarily
an Io_signal_handler to wait for changes of the devices ROM, and
try the device aquisition again. Thereby, simple drivers so not have
to take the burden to do so.

To enable this feature for all drivers, we always have to export a
devices ROM, but limit the information about physical resources
(I/O memory addresses, IRQ numbers, I/O port ranges) to clients with
'info=yes' in their policy description.

If PCI devices happen to miss complete configuration after boot, the

(specified by bus-device-functions tuples). The
<bar> node instructs the platform driver to remap BAR id 0 to address

required for BARs with address 0.

! <pci-fixup bus="0" device="0x15" function="3">

b8e2b780e3 nvme_drv: reject requests with unaligned offset
Since the driver relies on all requests being Nvme::MPS_LOG2 aligned
as advertised in its Block::Info the added check will reject any
misaligned requests (using 'gpt_write' led to an IOMMU write fault).

8d00af1d7b gems/decorators: adjust resources for WQHD displays
2560x1440 resolutions require more RAM resources. Additionally, make
sure that the decorator 'init' receives enough CAPs to service the

4b983f92c5 lx_emul: support execution till condition applies
In rare cases it is necessary to execute Linux contributed code
until certain work is finished, e.g. when in a synchronous RPC call,
a session construction or destruction a result is needed. Therefore,
we introduce a new lx_emul function called lx_emul_execute_kernel_until.

2fd2b7d628 lx_kit: map I/O mem with proper offset
In case multiple devices shared the same memory-mapped I/O page
we have to take the offset into account. This commit fixes the
'pc_usb_host_drv' on the Thinkpad X201 where the two EHCI host
controller share the some I/O memory page.

0d163915d0 nova: avoid hangs on AMD with IOMMUs
With the new usb driver #4399 and usage of the updated dde_linux lx_eml/lx_kit
approach a much higher rate of IRQ session construction/destruction and signal
handler assignment (irq->sigh) are caused. This trickles down to the kernel,
which causes an hang of the AMD IOMMUs due to not setting reserved bits
adequately. The commit fixes the root cause in the kernel and add a guard
into core's to limit such driver behaviour.

25eb24299c machine.vbox6: add audio enabledIn/Out options
The file listed only enabled="false" in the audio adapter tag. However,
setting only this option to true isn't sufficient for guest audio to work.
One has to set also enabledIn respectively enabledOut in the same tag. The
new default vbox6 file reflects this.

7d6c592417 vfs/rump: handle split block I/O jobs
This patch fixes a potential data corruption issue that could occur when
issuing large I/O requests to vfs/rump, which don't fit into the default
block I/O buffer of 128 KiB. Note that we haven't observed the problem
in practice (Sculpt hosts vfs/rump in a dedicated vfs server, which
fragments requests) but spotted the issue while reviewing the code. We
could trigger problem by explicitly changing the I/O buffer size to 32
KiB.

d815322efe os: simplify split block operations
This patch changes the meaning of the 'offset' parameter of the
'produce_write_content' and 'consume_read_result' hook functions.
The value used to reflect the absolute byte position but in practice,
a job-relative byte offset is desired.
