BusyBox's 'cmp' command doesn't support the '--bytes' parameter.
Some CIs -- i.e. LKFT -- use BusyBox and have the mptcp_join.sh test
failing [1] because their 'cmp' command doesn't support this '--bytes'
option:
cmp: unrecognized option '--bytes=1024'
BusyBox v1.35.0 () multi-call binary.
Usage: cmp [-ls] [-n NUM] FILE1 [FILE2]
Instead, 'head --bytes' can be used as this option is supported by
BusyBox. A temporary file is needed for this operation.
Because it is apparently quite common to use BusyBox, it is certainly
better to backport this fix to impacted kernels.

Most of the code had an issue according to ShellCheck.
That's mainly due to the fact it incorrectly believes most of the code
was unreachable because it's invoked by variable name, see how the
"tests" array is used.
Once SC2317 has been ignored, three small warnings were still visible:
- SC2155: Declare and assign separately to avoid masking return values.
- SC2046: Quote this to prevent word splitting: can be ignored because
"ip netns pids" can display more than one pid.
- SC2166: Prefer [ p ] || [ q ] as [ p -o q ] is not well defined.
This probably didn't fix any actual issues but it might help spotting
new interesting warnings reported by ShellCheck as just before,
ShellCheck was reporting issues for most lines making it a bit useless.

mptcp_connect tool was printing some duplicated entries when showing how
to use it: -j -l -r
While at it, I also:
- moved the very few entries that were not sorted,
- added -R that was missing since
commit 8a4b910d00 ("mptcp: selftests: add rcvbuf set option"),
- removed the -u parameter that has been removed in
commit f730b65c9d ("selftests: mptcp: try to set mptcp ulp mode in different sk states").
No need to backport this, it is just an internal tool used by our

Simply adding a "sleep" before checking something is usually not a good
idea because the time that has been picked can not be enough or too
much. The best is to wait for events with a timeout.
In this selftest, 'sleep 0.5' is used more than 40 times. It is always
used before calling a 'verify_*' function except for this
verify_listener_events which has been added later.
At the end, using all these 'sleep 0.5' seems to work: the slow CIs
don't complain so far. Also because it doesn't take too much time, we
can just add two more 'sleep 0.5' to uniform what is done before calling
a 'verify_*' function. For the same reasons, we can also delay a bigger
refactoring to replace all these 'sleep 0.5' by functions waiting for
events instead of waiting for a fix time and hope for the best.

These 'endpoint' tests from 'mptcp_join.sh' selftest start a transfer in
the background and check the status during this transfer.
Once the expected events have been recorded, there is no reason to wait
for the data transfer to finish. It can be stopped earlier to reduce the
execution time by more than half.
For these tests, the exchanged data were not verified. Errors, if any,
were ignored but that's fine, plenty of other tests are looking at that.
It is then OK to mute stderr now that we are sure errors will be printed
(and still ignored) because the transfer is stopped before the end.

This can be enabled via a new option: -o MPTFO.
Once enabled, the TCP_FASTOPEN socket option is enabled for the server
side and a sendto() with MSG_FASTOPEN is used instead of a connect() for
the client side.
Note that the first SYN has a limit of bytes it can carry. In other
words, it is allowed to send less data than the provided one. We then
need to track more status info to properly allow the next sendmsg()
starting from the next part of the data to send the rest.
Also in TFO scenarios, we need to completely spool the partially xmitted
buffer -- and account for that -- before starting sendfile/mmap xmit,
otherwise the relevant tests will fail.

Stop using the KSFT_KHDR_INSTALL flag as installing the kernel headers
from the kselftest Makefile is causing some issues. Instead, rely on
the headers to be installed directly by the top-level Makefile
"headers_install" make target prior to building kselftest.

The new script was not listed in the programs to test.
By consequence, some CIs running MPTCP selftests were not validating
these new tests. Note that MPTCP CI was validating it as it executes all
.sh scripts from 'tools/testing/selftests/net/mptcp' directory.

The usage header of pm_nl_ctl command doesn't match with the context. So
this patch adds the missing userspace PM keywords 'ann', 'rem', 'csf',

There're some 'Terminated' messages in the output of userspace pm tests
script after killing './pm_nl_ctl events' processes:
Created network namespaces ns1, ns2 [OK]
./userspace_pm.sh: line 166: 13735 Terminated ip netns exec "$ns2" ./pm_nl_ctl events >> "$client_evts" 2>&1

Established IPv6 MPTCP Connection ns2 => ns1 [OK]

This patch adds a helper kill_wait(), in it using 'wait $pid 2>/dev/null'
commands after 'kill $pid' to avoid printing out these Terminated messages.
Use this helper instead of using 'kill $pid'.

The mentioned test measures the transfer run-time to verify
that the user-space program is able to use the full aggregate B/W.
Even on (virtual) link-speed-bound tests, debug kernel can slow
down the transfer enough to cause sporadic test failures.
Instead of unconditionally raising the maximum allowed run-time,
tweak when the running kernel is a debug one, and use some simple/
rough heuristic to guess such scenarios.
Note: this intentionally avoids looking for /boot/config-<version> as
the latter file is not always available in our reference CI
environments.

This change updates the testing sample (pm_nl_ctl) to exercise
the updated MPTCP_PM_CMD_SET_FLAGS command for userspace PMs to
issue MP_PRIO signals over the selected subflow.
E.g. ./pm_nl_ctl set 10.0.1.2 port 47234 flags backup token 823274047 rip 10.0.1.1 rport 50003
userspace_pm.sh has a new selftest that invokes this command.
