This patch moves endpoint settings out of do_transfer() into a new
helper pm_nl_set_endpoint(). And invoke this helper in do_transfer().
This makes the code much more clearer.

run_tests() accepts too many optional parameters. Before this modification,
it was required to set all of then when only the last one had to be
changed. That's not clear to see all these 0 and it makes the maintenance
harder:
run_tests $ns1 $ns2 10.0.1.1 1 2 3 slow
Instead, the parameter can be set as an env var with a limited scope:
foo=1 bar=2 next=3 \
run_tests $ns1 $ns2 10.0.1.1 slow
This patch switches to key/value "sflags=*" instead of positional parameter
sflags of do_transfer() and run_tests().

New MPTCP info are being checked in multiple places to improve the code
coverage when using the userspace PM.
This patch makes chk_mptcp_info() more generic to be able to check
subflows, add_addr_signal and add_addr_accepted info (and even more
later). New arguments are now required to get different infos from the
two namespaces because some counters are specific to the client or the
server.

test into a new function userspace_pm_add_addr(), and remove address test
into userspace_pm_rm_sf_addr_ns1(). Move add subflow test into

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the MPTCP MIB counters introduced in commit fc518953bc9c
("mptcp: add and use MIB counter infrastructure") and more later. The
MPTCP Join selftest heavily relies on these counters.
If a counter is not supported by the kernel, it is not displayed when
using 'nstat -z'. We can then detect that and skip the verification. A
new helper (get_counter()) has been added recently in the -net tree to
do the required checks and return an error if the counter is not
available.
This commit is similar to the one with the same title applied in the
-net tree but it modifies code only present in net-next for the moment,
see the Fixes commit below.
While at it, we can also remove the use of ${extra_msg} variable which
is never assigned in chk_rm_tx_nr() function and use 'echo' without '-n'
parameter.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the support of a mix of subflows in v4 and v6 by the
in-kernel PM introduced by commit b9d69db87fb7 ("mptcp: let the
in-kernel PM use mixed IPv4 and IPv6 addresses").
It looks like there is no external sign we can use to predict the
expected behaviour. Instead of accepting different behaviours and thus
not really checking for the expected behaviour, we are looking here for
a specific kernel version. That's not ideal but it looks better than
removing the test because it cannot support older kernel versions.

The alignment was different from the other tests because tabs were used
instead of spaces.
While at it, also use 'echo' instead of 'printf' to print the result to
keep the same style as done in the other sub-tests. And, even if it
should be better with, also remove 'stdbuf' and sed's '--unbuffered'
option because they are not used in the other subtests and they are not
available when using a minimal environment with busybox.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the support of the fullmesh flag for the in-kernel PM
introduced by commit 2843ff6f36db ("mptcp: remote addresses fullmesh")
and commit 1a0d6136c5f0 ("mptcp: local addresses fullmesh").
It looks like there is no easy external sign we can use to predict the
expected behaviour. We could add the flag and then check if it has been
added but for that, and for each fullmesh test, we would need to setup a
new environment, do the checks, clean it and then only start the test
from yet another clean environment. To keep it simple and avoid
introducing new issues, we look for a specific kernel version. That's
not ideal but an acceptable solution for this case.

Selftests are supposed to run on any kernels, including the old ones not

Commit bccefb762439 ("selftests: mptcp: simplify pm_nl_change_endpoint")
has simplified the way the backup flag is set on an endpoint. Instead of
doing:
./pm_nl_ctl set 10.0.2.1 flags backup
Now we do:
./pm_nl_ctl set id 1 flags backup
The new way is easier to maintain but it is also incompatible with older
kernels not supporting the implicit endpoints putting in place the
infrastructure to set flags per ID, hence the second Fixes tag.

Note that here and in the following commits, we re-do the same check for
each sub-test of the same function for a few reasons. The main one is
not to break the ID assign to each test in order to be able to easily
compare results between different kernel versions. Also, we can still
run a specific test even if it is skipped. Another reason is that it
makes it clear during the review that a specific subtest will be skipped
or not under certain conditions. At the end, it looks OK to call the
exact same helper multiple times: it is not a critical path and it is
the same code that is executed, not really more cases to maintain.

change but because in these selftests, we check some internal

having added some features.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
Some tests are using IPTables and/or TC commands to force some
behaviours. If one of these commands fails -- likely because some
features are not available due to missing kernel config -- we should
intercept the error and skip the tests requiring these features.
Note that if we expect to have these features available and if
SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var is set to 1, the tests
will be marked as failed instead of skipped.
This patch also replaces the 'exit 1' by 'return 1' not to stop the
selftest in the middle without the conclusion if there is an issue with
NF or TC.

avoid issues we had in the past, e.g. with MPTcpExtRmAddr and
MPTcpExtRmAddrDrop sharing the same prefix. While at it, we uniform the
way we fetch a MIB counter.
Note for the backports: we rarely change these modified blocks so if
there is are conflicts, it is very likely because a counter is not used
in the older kernels and we don't need that chunk.

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.

If a test case fails, the mptcp_join.sh script can dump the
netns MIBs multiple times, leading to confusing output.
Let's dump such info only once per test-case, when needed.
This additionally allow removing some code duplication.

Currently we don't track explicitly a few events related to address
management suboption handling; this patch adds new mibs for ADD_ADDR
and RM_ADDR options tx and for missed tx events due to internal storage
exhaustion.
The self-tests must be updated to properly handle different mibs with
the same/shared prefix.
Additionally removes a couple of warning tracking the loss event.

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.

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.

A test-case is frequently failing on some extremely slow VMs.
The mptcp transfer completes before the script is able to do
all the required PM manipulation.
Address the issue in the simplest possible way, making the
transfer even more slow.
Additionally dump more info in case of failures, to help debugging
similar problems in the future and init dump_stats var.

This patch adds test coverage for listening sockets created by the
in-kernel path manager in mptcp_join.sh.
It adds the listener event checking in the existing "remove single
address with port" test. The output looks like this:
003 remove single address with port syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ] - pt [ ok ]
syn[ ok ] - synack[ ok ] - ack[ ok ]
syn[ ok ] - ack [ ok ]
rm [ ok ] - rmsf [ ok ] invert

This patch moves evts_ns1 and evts_ns2 out of do_transfer() as two global
variables in mptcp_join.sh. Init them in init() and remove them in
cleanup().
Add a new helper reset_with_events() to save the outputs of 'pm_nl_ctl
events' command in them. And a new helper kill_events_pids() to kill
pids of 'pm_nl_ctl events' command. Use these helpers in userspace pm
tests.

Some userspace pm tests failed since pm listener events have been added.
Now MPTCP_EVENT_LISTENER_CREATED event becomes the first item in the
events list like this:
type:15,family:2,sport:10006,saddr4:0.0.0.0
type:1,token:3701282876,server_side:1,family:2,saddr4:10.0.1.1,...
And no token value in this MPTCP_EVENT_LISTENER_CREATED event.
This patch fixes this by specifying the type 1 item to search for token
values.

After the previous patches, the MPTCP protocol can generate
fast-closes on both ends of the connection. Rework the relevant
test-case to carefully trigger the fast-close code-path on a
single end at the time, while ensuring than a predictable amount
of data is spooled on both ends.
Additionally add another test-cases for the passive socket
fast-close.
