Prevent errors if precision and left alignment are part of the string.
String precision is applied to limit access to the configured number of
characters but ignored for other types.

Failed allocations were still denoted with a successful return value
to the caller. This situation was triggered by artificial testing and
has not been observed yet in practice. In case the 'LIMA_GEM_CREATE'
I/O control fails Mesa will dereference invalid pointers anyway.

This patch changes the unlink operation of the ram fs to defer the
destruction of a file until it is no longer referenced by any VFS handle.
When unlinked, the file no longer appears in the directory. But it can
still be opened and accessed.
With this change, a parent process of a Unix-like subsystem becomes able
to pass the content of an unlinked file to a forked child process. This
mechanism is required when using the 'exec' command in Tcl scripts.
Another use case is the 'tmpfile()' function.

By using `mktime()`, which assumes local time, we render the `TZ`
environment variable ineffective. Instead, `timegm()` should be used to
set the real-time clock to UTC.

This option is useful in cases where batching is configured and

This is a follow-up commit to the adaptation of the run scripts to the
consistent use of [build_artifacts] (issue #4860).
The missing build of libm remained undetected until the recent removal
of implicit shared-library builds (issue #5061).
Currently, running ripgrep on Genode emits
"Warning: sysconf(71) not implemented".
Return -1 without setting errno, which is a valid return value according
to getpwnam(3) and silence the warning.

FreeBSD libc code uses only a single spinlock instance and, thus there
is no obvious reason why it would need to be implemented as an actual
spinlock. _spinlock() and _spinunlock() functions are implemented with a
static pthread mutex.

This commit adds a new configuration option, `dst_addr` to the
'sntp_client' that accepts either an IP address or a DNS hostname. If a
DNS hostname is provided, the 'sntp_client' will resolve the IP address
before each SNTP request. The 'dst_ip' configuration option is
deprecated but kept for compatibility until 'dst_addr' is fully adopted.

Per Affinity::Location a system control cap can be requested. The capability
provides an RPC interface to request and set Cpu_state, as provided by the
former Pd::managing_system(Cpu_state) method. Invocation of those system
control capabilities then *can* (see below) be executed on the desired CPU
as described by Affinity::Location.
The system control cap will be invalid for kernels that don't support
system_control/managing_system functionality at all.
The system control cap will be ever by the same, e.g. ignoring the
Affinity::Location parameter, if the used kernel doesn't support or doesn't
require the feature to execute the system control per CPU.
The commit is a preparation step to add guarded and selective x86 MSR
access per CPU.
Fixes#5009
Internally libyuv uses malloc & free for short time dynamic memory
allocation during image transformation. The converted images are
such large, that the Libc allocator will create and destroy new Genode
dataspace per image. In time sensitive code paths, the overhead can be
noticeable by the caller of the image transformation.
The patch adds the option to register callbacks in the libyuv library to
implement the image allocation by users of the library. They may implement
caching strategies to avoid the overhead, e.g. as seen with qemu-usb and
the webcam model.
and not before. On Windows guest with more than 1 vCPU, the packets
seem to arrive and/or seem to be handled too late in the Webcam model.
An intermediate state, to due the late packet, has been used to decide to
close the Capture session too early.
Dynamically loading the `compat-libc` breaks `fork(2)` on Genode.
Switch `compat-libc` to a special api package that provides a source
file for statically linking the library, analogous to the `blit`
package. This also requires a quirk in Goa but should prevent breaking
`fork()` and removes the runtime and archive dependencies for Rust
packages using `compat-libc`.

Implement FBSD_1.0 versions of libc functions ('stat', 'fstat'). The
functions are versioned with @FBSD_1.0, and therefore, will not clash
with libc during linking. However, to be called by our dynamic linker,
the library must be before libc in the NEEDED section of the binary
using it. This requires the lib to be in front of libc in the LIBS
variable. The library currently will call libc 'stat' and 'fstat' by
looking up the symbols via 'dlsym'.

* Removes the <event> tag from all test package runtime files and replaces the
contained <timeout> and <log> sub-tags with the new tags <succeed> and
<fail>. If a <succeed> or <fail> tag has a content, it defines a log pattern
that should be recognized and render the test failed or successful. If a
<succeed> or <fail> tag has an attribute after_seconds that is not set to 0,
it defines a timeout after which the test should be rendered failed or
successful.
* Adapts the Depot Autopilot to support the new syntax in the test-package
runtime files. However, for now, the Depot Autopilot is kept compatible to
the old syntax as well. If the <events> tag is present, it is prioritized
over the new syntax.

Several nightly network-related tests fail currently on sel4/pc because the
new e1000 NIC driver requires more capabilities. The "drivers nic" package
was already adapted to the new requirement but some tests fail to provide
enough caps to the corresponding sub system. This commit tries to fix all
remaining tests.

In case the meta data (or more) got zeroed upon 'free', print error
message. The offset in the meta data can never be zero. This does not
help on other memory corruptions, but at least gives a hint in the too
much zeroed out case.

This patch solves the false-negative error message "failed to open file"
referring to an ioctl info file during an ioctl call. The message is
now avoided by checking for the existence of the file before reading it.
However, the observed symptom uncovered an actual bug that was
introduced in commit "libc vfs: open OSS 'info' file only once" with
the attempt to cache the content of ioctl info files. When called
multiple time for different paths, 'Vfs_plugin::_with_info' would
wrongly return the info from the first call as cached in a local
static variable.
The patch fixes the problem by a new added 'Cached_ioctl_info'
implementation in the scope of the 'Vfs_plugin'.
