This patch adds a new variable MPTCP_LIB_TEST_FORMAT as the test title
printing format. Also add a helper mptcp_lib_print_title() to use this
format to print the test title with test counters. They are used in
mptcp_join.sh first.
Each MPTCP selftest is having subtests, and it helps to give them a
number to quickly identify them. This can be managed by mptcp_lib.sh,
reusing what has been done here. The following commit will use these
new helpers in the other tests.

Variable TEST_COUNT are used in mptcp_connect.sh and mptcp_join.sh as
test counters, which are initialized to 0, while variable test_cnt are used
in diag.sh and simult_flows.sh, which are initialized to 1. To maintain

initializes it to 1, and exports it into mptcp_lib.sh.

But then, the "pm_nl_ctl events" was launched a first time, killed, then
relaunched after for no particular reason.

To avoid duplicated code in different MPTCP selftests, we can add and
use helpers defined in mptcp_lib.sh.
This patch unifies "pm_nl_ctl events" related code in userspace_pm.sh
and mptcp_join.sh into a helper mptcp_lib_events(). Define it in
mptcp_lib.sh and use it in both scripts.
Note that mptcp_lib_kill_wait is now call before starting 'events' for
mptcp_join.sh as well, but that's fine: each test is started from a new
netns, so there will not be any existing pid there, and nothing is done
when mptcp_lib_kill_wait is called with 0.

This was needed because of some issues that were visible when testing
the kselftests on a v5.15.x with iptables-nft as default backend. It
looks like these errors are no longer present. As mentioned by Pablo [1],
the errors were maybe due to missing kernel config. We can then use
iptables-nft if it is the default one, instead of using a legacy tool.
We can then check the variables iptables and ip6tables are valid. We can
keep the variables to easily change it later or add options.

When creating a lot of listener sockets, it is enough to wait only for
the last one, like we are doing before in diag.sh for other subtests.
If we do a check for each listener sockets, each time listing all
available sockets, it can take a very long time in very slow
environments, at the point we can reach some timeout.
When using the debug kconfig, the waiting time switches from more than
8 sec to 0.1 sec on my side. In slow/busy environments, and with a poll
timeout set to 30 ms, the waiting time could go up to ~100 sec because
the listener socket would timeout and stop, while the script would still
be checking one by one if all sockets are ready. The result is that
after having waited for everything to be ready, all sockets have been
stopped due to a timeout, and it is too late for the script to check how
many there were.
While at it, also removed ss options we don't need: we only need the
filtering options, to count how many listener sockets have been created.
We don't need to ask ss to display internal TCP information, and the
memory if the output is dropped by the 'wc -l' command anyway.

It is important to have a unique (sub)test name in TAP, because some CI
environments drop tests with duplicated name.
When adding a new subtest entry, an error message is printed in case of
duplicated entries. If there were duplicated entries and if all features
were expected to work, the script exits with an error at the end, after
having printed all subtests in the TAP format. Thanks to that, the MPTCP
CI will catch such issues early.

The mptcp diag interface already experienced a few locking bugs
that lockdep and appropriate coverage have detected in advance.
Let's add a test-case triggering the relevant code path, to prevent
similar issues in the future.
Be careful to cope with very slow environments.
Note that we don't need an explicit timeout on the mptcp_connect
subprocess to cope with eventual bug/hang-up as the final cleanup
terminating the child processes will take care of that.

It is important to have a unique (sub)test name in TAP, because some CI

Some 'cestab' subtests from the diag selftest had the same names, e.g.:
....chk 0 cestab
Now the previous value is taken, to have different names, e.g.:
....chk 2->0 cestab after flush
While at it, the 'after flush' info is added, similar to what is done
with the 'in use' subtests. Also inspired by these 'in use' subtests,
'many' is displayed instead of a large number:
many msk socket present [ ok ]
....chk many msk in use [ ok ]
....chk many cestab [ ok ]
....chk many->0 msk in use after flush [ ok ]
....chk many->0 cestab after flush [ ok ]

It is important to have a unique (sub)test name in TAP, because some CI
environments drop tests with duplicated names.
Some subtests from the userspace_pm selftest had the same names. That's
because different subflows are created (and deleted) between the same
pair of IP addresses.
Simply adding the destination port in the name is then enough to have
different names, because the destination port is always different.
Note that adding such info takes a bit more space, so we need to
increase a bit the width to print the name, simply to keep all the
'[ OK ]' aligned as before.

If a CI executes the same selftest multiple times with different

which confuse the CI. With the same title printed in TAP, the tests are
considered as the same ones.
Now, it is possible to override this prefix by using MPTCP_LIB_KSFT_TEST
env var, and have a different title.
While at it, use 'basename' to remove the suffix as well instead of

When running the simult_flow selftest in slow environments -- e.g. QEmu
without KVM support --, the results can be unstable. This selftest
checks if the aggregated bandwidth is (almost) fully used as expected.
To help improving the stability while still keeping the same validation
in place, the BW and the delay are reduced to lower the pressure on the
CPU.

On very slow environments -- e.g. when QEmu is used without KVM --,
mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the
default timeout by 50% as it seems normal to take that long on some
environments.
When a debug kernel config is used, this selftest will take even longer,
but that's certainly not a common test env to consider for the timeout.
The Fixes tag that has been picked here is there simply to help having
this patch backported to older stable versions. It is difficult to point
to the exact commit that made some env reaching the timeout from time to
time.
