Now, we schedule before unblocking the rx_task. This is done in order to
execute a potentially ready ksoftirqd before unblocking the rx_task,
which in turn may execute soft-interrupt handlers through bottom half
code leading to double lock attempts of the socket spinlock.
Issue #5264
The commit that added firmware loading via the VFS (see #4861)
introduces a double-free bug where the memory that contains the
image is freed twice, once from the callback and once from the
work function.
As alle examined drivers call 'release_firmware' from the callback
function themselves, remove the erroneous 'kfree' call from the
work function.
Issue #5264.
This commit introduces support for querying and updating the signal
quality of the established connection to the current accesspoint.
By setting the 'update_quality_interval' to a non-zero value specified
in seconds the 'state' report will be updated to incorporate the
current signal quality. It uses the same approximation as is already
in use by the scan results.
Fixes#5262.
This commit adds the firmware image for the AX200 device as found
in the Tuxedo Pulse 15 Gen1, the 9560 as found in the Starlite and
the for devices found in the T430/T530.
Fixes#5282.
Unmasking of a pending interrupt did not lead to immediate IRQ handler
execution in all cases.
This commit also addresses some style concerns risen during the issue
discussion.
- Replace multi-boolean IRQ state by state enum
- EOI and ACK should be same in DDE context
- Unify x86 and ARM irqchip.c
- Remove Pending_irq type
- Remove dde_irq_set_wake()
Fixes#5164
The use of the Linux-internal SLUB allocator is supported by lx_emul and
drivers may now decide between the Linux implementation or our emulation
of kmem_cache. Drivers for pc and virt already use SLUB, while other
drivers still use the emulation and may be adapted step-by-step incl.
the testing on the devices.
Fixes#5236
The Fn key on keyboards should never be reported as real scancode event,
as it is just a hardware switch that changes the reported scancodes of
other keys. The behavior of Linux hid-apple.c is wrong as it on one hand
reports different scancodes for the same hard key depending on the Fn
state but sends the Fn press and release events too. Thus from now on,
we just drop KEY_FN events for all drivers as otherwise, scancodes
generated generated by Fn+key combinations would never be single-key
events on upper layers, for example KEY_FN + KEY_F12 on the Matias Apple
keyboard clone in the fixed issue.
Fixes#5288
With libxml2 >= 2.13, the `-path` argument can no longer be used for
setting search paths for xsd files. Instead, we use an XML catalog to
replace genode:// URIs with absolute paths.
Fixes#5248
So far, this test used dynamic_rom for the re-configuration of the nic router
and tested for the expected ping results by inspecting the log with the run
tool. However, this approach had two issues:
* Timing differs significantly on different targets and so the dynamic_rom had
the difficult task of compensating with heuristics without bloating the test
duration too much.
* In case of a failing test, it was difficult to determine the cause as the
test kept running and produced output for quite some time and there was also
no specific error message but only a generic timeout.
These two issues are now fixed by introducing a test component that listens to
the ping-result report and manages the nic router configuration. The new
component exits early on failure and provides information on the error
circumstances. Furthermore, the component advances to the next test step only
after having seen the expected result of the active test step and thereby
removes the need for heuristics about target timing.

- 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
This commit adds a weak dummy implementation to a compilation unit
that is referenced by all DDE Linux based driver components to
prevent adding a dummy to every driver.
The upstream implementation is used to allocate order-0 pages in
a batch and users, e.g. page-pool allocator, may rely on that
behaviour and thus it is implemented with this commit.
This commit remedies the somewhat lazy attempt to address unique names
for drivers where the name is directly derived from KBUILD_MODNAME,
e.g. rtlwifi, and also modifies the name accordingly to the rules
of Linux' build-system. The last part becomes necessary as driver
matching tables may rely on that as has already happend with the
ti-sn65dsi86 driver.
At least on x86_64/x86_64/pc/hw|nova, the test used to fail because the net
setup sometimes required more than the 3 seconds that the test was giving each
step. This commit raises the step timeout to 5 seconds and the test timeout
from 70 to 90 seconds in order to be on the safe side.

This commits updates the contrib sources to version 8.7.1.
This version requires more random entropy as it queries OpenSSL
about the current random state and will bail if it is not sufficient.
Doubling the content of the '<inline>' VFS plugin as used in static
configurations seems satisfactory.
Furthermore DNS resolving needs a configured '<pipe>' plugin to work
properly.
Fixes#5184.
Commit 'wifi_drv: re-arm scan timer when enabled again' allowed for
re-arming the scan timer but still uses the old timer value the first
time around. If the timer was disabled, by setting the interval to 0,
it was not enabled again.
We now check if the interval has changed beforehand and potentially
arm the scan timer afterwards.
Fixes#5178.
Because all operations in lxip are non-blocking, return
WRITE_ERR_WOULD_BLOCK for data writes as done by read.
Note: This was not the case in the old plugin because 'write' was blocking
operation there.
issue #5165
Rarely. it might happen that events got received shortly before the complete
set of relevant USB devices got recognized. Filter more output in test metric
to stay robust.
All errors (as in the legacy version) are now propagated as WRITE_ERR_IO
(see Lxip_vfs_file_handle::write), which ultimately will lead to EPIPE
in libc's socket_fs. This also counts for EAGAIN leading to the fact
that partial writes are not supported for blocking sockets in libc, also
libc will not try a second time in case not all data has been written.
issue #5165
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
pci_channel_offline() checks if this member is set to
pci_channel_io_normal (which is 1). The former value of 0 is invalid.
This change fixes pc_nic_drv link down-up in cases that require an e1000
reset.
lx_emul_trace_msg() uses Genode::trace() as message function for
lightweight trace points, but also supports Linux format-string
attributes by using vsnprintf().
This is function gets called by some libssh applications using vms_lxip.
For the dummy implementation I looked at the old port.

Issue gapfruit#1976
The added hook 'OBJ_POSTPROC_SRC' gives us a way to post-process object
files for generating supplemental code. By using this hook, the
initcall_table.c generated by import-lx_emul_common.inc gets reliably
executed after all object files are built.
Fixes#5159
