This modification is linked to the parent commit where the received
ADD_ADDR limit was accidentally reset when the endpoints were flushed.
To validate that, the test is now flushing endpoints after having set
new limits, and before checking them.
The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

dynptr for skb metadata behaves the same way as the dynptr for skb data
with one exception - writes to skb_meta dynptr don't invalidate existing
skb and skb_meta slices.
Duplicate those the skb dynptr tests which we can, since
bpf_dynptr_from_skb_meta kfunc can be called only from TC BPF, to cover the
skb_meta dynptr verifier checks.
Also add a couple of new tests (skb_data_valid_*) to ensure we don't
invalidate the slices in the mentioned case, which are specific to skb_meta
dynptr.

LLVM/clang can not build the kernel for all architectures supported by
nolibc. The current setup uses the same compiler to build the kernel as
is used for nolibc-test. This prevents using the full qemu-system tests
for LLVM builds.
Instead always build the kernel with GCC. For the nolibc testsuite the
kernel does not need to be built with LLVM.

Validate that all indirect calls adhere to kCFI rules. Notably doing
nocfi indirect call to a cfi function is broken.
Apparently some Rust 'core' code violates this and explodes when ran
with FineIBT.
All the ANNOTATE_NOCFI_SYM sites are prime targets for attackers.
- runtime EFI is especially henous because it also needs to disable
IBT. Basically calling unknown code without CFI protection at
runtime is a massice security issue.

The CI has hit a couple of cases of:
RUN global.data_steal ...
tls.c:2762:data_steal:Expected recv(cfd, buf2, sizeof(buf2), MSG_DONTWAIT) (20000) == -1 (-1)
data_steal: Test terminated by timeout
FAIL global.data_steal
Looks like the 2msec sleep is not long enough. Make the sleep longer,
and then instead of second sleep wait for the thieving process to exit.
That way we can be sure it called recv() before us.
While at it also avoid trying to steal more than a record, this seems
to be causing issues in manual testing as well.

Previously, re-using pinned DEVMAP maps would always fail, because
get_map_info on a DEVMAP always returns flags with BPF_F_RDONLY_PROG set,
but BPF_F_RDONLY_PROG being set on a map during creation is invalid.
Thus, ignore the BPF_F_RDONLY_PROG flag in the flags returned from
get_map_info when checking for compatibility with an existing DEVMAP.
The same problem is handled in a third-party ebpf library:

Based on a bisect, it appears that commit 7ee988770326 ("timers:
Implement the hierarchical pull model") has somehow inadvertently
broken BPF selftest test_tcpnotify_user. The error that is being
generated by this test is as follows:
FAILED: Wrong stats Expected 10 calls, got 8
It looks like the change allows timer functions to be run on CPUs
different from the one they are armed on. The test had pinned itself
to CPU 0, and in the past the retransmit attempts also occurred on CPU
0. The test had set the max_entries attribute for
BPF_MAP_TYPE_PERF_EVENT_ARRAY to 2 and was calling
bpf_perf_event_output() with BPF_F_CURRENT_CPU, so the entry was
likely to be in range. With the change to allow timers to run on other
CPUs, the current CPU tasked with performing the retransmit might be
bumped and in turn fall out of range, as the event will be filtered
out via __bpf_perf_event_output() using:
if (unlikely(index >= array->map.max_entries))
return -E2BIG;
A possible change would be to explicitly set the max_entries attribute
for perf_event_map in test_tcpnotify_kern.c to a value that's at least
as large as the number of CPUs. As it turns out however, if the field
is left unset, then the libbpf will determine the number of CPUs available
on the underlying system and update the max_entries attribute accordingly
in map_set_def_max_entries().
A further problem with the test is that it has a thread that continues
running up until the program exits. The main thread cleans up some
LIBBPF data structures, while the other thread continues to use them,
which inevitably will trigger a SIGSEGV. This can be dealt with by
telling the thread to run for as long as necessary and doing a
pthread_join on it before exiting the program.
Finally, I don't think binding the process to CPU 0 is meaningful for
this test any more, so get rid of that.

Skipped tests reported by kselftest.h use a different format than KTAP,
there is no explicit test name. Normally the test name is part of the
free-form string after the SKIP keyword:
ok 3 # SKIP test: some reason
Extend the parser to handle those correctly. Use the free-form string as
test name instead.

support.
The cpufreq subsystem has a generic sysfs interface for controlling boost
(/sys/devices/system/cpu/cpufreq/boost).
The sysfs interface can be used to enable boost control from the cpupower
command on non-x86 platforms as well. So, allow boost controlling
on non-x86 system if boost sysfs file exists.
The set subcommand enables/disables the boost feature using the following
syntax:
cpupower set --boost 1
cpupower set --boost 0
The --boost option is an alias for --turbo-boost. We provided the neutral
option name because the name "turbo boost" is specific to Intel technology.
The frequency-info subcommand displays the enabled/disabled state of
the boost feature as follows:
boost state support:
Active: yes (or no)

The set subcommand's -t option is documented as being available for boost
configuration, but it was not actually functioning due to a bug
in the option handling.

Add tests to ensure proper backlog accounting in hhf, codel, pie, fq,
fq_pie, and fq_codel qdiscs. We check for the bug pattern originally
found in fq, fq_pie, and fq_codel, which was an underflow in the tbf
parent backlog stats upon child qdisc removal.

On fast machines the tests run in quick succession so even
when tests clean up after themselves the carrier may need
some time to come back.
Specifically in NIPA when ping.py runs right after netpoll_basic.py
the first ping command fails.
Since the context manager callbacks are now common NetDrvEpEnv
gets an ip link up call as well.
