[ Upstream commit 414f50434a ]
Some newer cards supported by aacraid can take up to 40s to recover
after an EEH event. This causes spurious failures in the basic EEH
self-test since the current maximim timeout is only 30s.
Fix the immediate issue by bumping the timeout to a default of 60s,
and allow the wait time to be specified via an environmental variable
(EEH_MAX_WAIT).

[ Upstream commit ea6a547669 ]
The SO_TXTIME test depends on accurate timers. In some virtualized
environments the test has been reported to be flaky. This is easily
reproduced by disabling kvm acceleration in Qemu.
Allow greater variance in a run and retry to further reduce flakiness.
Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.
In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

[ Upstream commit ac87813d43 ]
Commit 852c8cbf34 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") adds support for a new per-test-directory "settings"
file. But this only works for tests not in a sub-subdirectories, e.g.
- tools/testing/selftests/rtc (rtc) is OK,
- tools/testing/selftests/net/mptcp (net/mptcp) is not.
We have to increase the timeout for net/mptcp tests which are not
upstreamed yet but this fix is valid for other tests if they need to add
a "settings" file, see the full list with:
tools/testing/selftests/*/*/**/Makefile
Note that this patch changes the text header message printed at the end
of the execution but this text is modified only for the tests that are
in sub-subdirectories, e.g.
ok 1 selftests: net/mptcp: mptcp_connect.sh
Before we had:
ok 1 selftests: mptcp: mptcp_connect.sh
But showing the full target name is probably better, just in case a
subsubdir has the same name as another one in another subdirectory.

[ Upstream commit 6b64a650f0 ]
It was observed[1] on arm64 that __builtin_strlen led to an infinite
loop in the get_size selftest. This is because __builtin_strlen (and
other builtins) may sometimes result in a call to the C library
function. The C library implementation of strlen uses an IFUNC
resolver to load the most efficient strlen implementation for the
underlying machine and hence has a PLT indirection even for static
binaries. Because this binary avoids the C library startup routines,
the PLT initialization never happens and hence the program gets stuck
in an infinite loop.
On x86_64 the __builtin_strlen just happens to expand inline and avoid
the call but that is not always guaranteed.
Further, while testing on x86_64 (Fedora 31), it was observed that the
test also failed with a segfault inside write() because the generated
code for the write function in glibc seems to access TLS before the
syscall (probably due to the cancellation point check) and fails
because TLS is not initialised.
To mitigate these problems, this patch reduces the interface with the
C library to just the syscall function. The syscall function still
sets errno on failure, which is undesirable but for now it only
affects cases where syscalls fail.

The rseq.h UAPI now documents that the rseq_cs field must be cleared
before reclaiming memory that contains the targeted struct rseq_cs, but
also that the rseq_cs field must be cleared before reclaiming memory of
the code pointed to by the rseq_cs start_ip and post_commit_offset
fields.
While we can expect that use of dlclose(3) will typically unmap
both struct rseq_cs and its associated code at once, nothing would
theoretically prevent a JIT from reclaiming the code without
reclaiming the struct rseq_cs, which would erroneously allow the
kernel to consider new code which is not a rseq critical section
as a rseq critical section following a code reclaim.

livepatch test configures the system and debug environment to run
tests. Some of these actions fail without root access and test
dumps several permission denied messages before it exits.
Fix test-state.sh to call setup_config instead of set_dynamic_debug
as suggested by Petr Mladek <pmladek@suse.com>

This test only works when [1] is applied, which was rejected.
Basically, the errors are reported and cleared. In this particular case of
tls sockets, following reads will block.
The test case was originally submitted with the rejected patch, but, then,
was included as part of a different patchset, possibly by mistake.

If a timeout failure occurs, kselftest kills the test process and prints
the timeout log. If the test process has killed while printing a log
that ends with new line, the timeout log can be printed in middle of the
test process output so that it can be seems like a comment, as below:
# test_process_log not ok 3 selftests: timers: nsleep-lat # TIMEOUT
This commit avoids such problem by printing one more line before the
