This patch moves userspace pm tests out of do_transfer(). Move add address
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
userspace_pm_add_sf() and remove subflow into
userspace_pm_rm_sf_addr_ns2().

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.

introduced by commit 2843ff6f36db ("mptcp: remote 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
supporting all MPTCP features.
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.

It is possible to look for "mptcp_subflow_send_ack" in kallsyms because

advance if the feature is supported instead of trying and accepting any

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.

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.

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.

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.

The definition of 'rndh' was probably copied from one script to another
but some times, 'sec' was not defined, not used and/or not spelled
properly.
Here all the 'rndh' are now defined the same way.

On slow or busy VM, some test-cases still fail because the
data transfer completes before the endpoint manipulation
actually took effect.
Address the issue by artificially increasing the runtime for
the relevant test-cases.

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.

Add the multiple subflows test case for MP_FAIL, to test the MP_FAIL
reset case. Use the test_linkfail value to make 1024KB test files.
Invoke reset_with_fail() to use 'iptables' and 'tc action pedit' rules
to produce the bit flips to trigger the checksum failures on ns2eth2.
Add delays on ns2eth1 to make sure more data can translate on ns2eth2.
The check_invert flag is enabled in reset_with_fail(), so this test
prints out the inverted bytes, instead of the file mismatch errors.
Invoke pedit_action_pkts() to get the numbers of the packets edited
by the tc pedit actions, and print this numbers to the output.

occurs:

Check userspace PM behavior to ensure ADD_ADDR echoes are only sent when
there is an active userspace daemon. If the daemon is restarting or
hasn't loaded yet, the missing echo will cause the peer to retransmit
the ADD_ADDR - and hopefully the daemon will be ready to receive it at
that later time.

These tests ensure that the in-kernel path manager is bypassed when
the userspace path manager is configured. Kernel code is still
responsible for ADD_ADDR echo, so also make sure that's working.
