This series of 9 patches fixes issues mostly identified by CI's not
managed by the MPTCP maintainers. Thank you Linero (LKFT) and Netdev
maintainers (NIPA) for running our kunit and selftests tests!
For the first patch, it took a bit of time to identify the root cause.
Some MPTCP Join selftest subtests have been "flaky", mostly in slow
environments. It appears to be due to the use of a TCP-specific helper
on an MPTCP socket. A fix for kernels >= v5.15.
Patches 2 to 4 add missing kernel config to support NetFilter tables
needed for IPTables commands. These kconfigs are usually enabled in
default configurations, but apparently not for all architectures.
Patches 2 and 3 can be backported up to v5.11 and the 4th one up to
v5.19.
Patch 5 increases the time limit for MPTCP selftests. It appears that
many CI's execute tests in a VM without acceleration supports, e.g. QEmu
without KVM. As a result, the tests take longer. Plus, there are more
and more tests. This patch modifies the timeout added in v5.18.
Patch 6 reduces the maximum rate and delay of the different links in
some Simult Flows selftest subtests. The goal is to let slow VMs reach
the maximum speed. The original rate was introduced in v5.11.
Patch 7 lets CI changing the prefix of the subtests titles, to be able
to run the same selftest multiple times with different parameters. With
different titles, tests will be considered as different and not override
previous results as it is the case with some CI envs. Subtests have been
introduced in v6.6.
Patch 8 and 9 make some MPTCP Join selftest subtests quicker by stopping
the transfer when the expected events have been seen. Patch 8 can be
backported up to v6.5.
