Since the "Fixes" commits mentioned below, the newly added "userspace
pm" subtests of mptcp_join selftests are launching the whole transfer in
the background, do the required checks, then wait for the end of
transfer.
There is no need to wait longer, especially because the checks at the
end of the transfer are ignored (which is fine). This saves quite a few
seconds on slow environments.

If a CI executes the same selftest multiple times with different
options, all results from the same subtests will have the same title,
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
using an extra 'sed'.

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.

The purpose of the test_LAG_cleanup() function is to check that some
hardware addresses are removed from underlying devices after they have been
unenslaved. The test function simply checks that those addresses are not
present at the end. However, if the addresses were never added to begin
with due to some error in device setup, the test function currently passes.
This is a false positive since in that situation the test did not actually
exercise the intended functionality.
Add a check that the expected addresses are indeed present after device
setup. This makes the test function more robust.
I noticed this problem when running the team/dev_addr_lists.sh test on a
system without support for dummy and ipv6:
tools/testing/selftests/drivers/net/team# ./dev_addr_lists.sh

The test functions use local variable 'a' for addresses and
then log_test is also using 'a' without a local declaration.
Fix by declaring a local variable and using 'ans' (for answer)

a reasonable compromise for the test. There is a plan in-line comment on

As the names of (struct test_key) members didn't reflect whether the key
was used for TX or RX, the verification for the counters was done
incorrectly for asymmetrical selftests.
Rename these with _tx appendix and fix checks in verify_counters().
While at it, as the checks are now correct, introduce skip_counters_checks,
which is intended for tests where it's expected that a key that was set
with setsockopt(sk, IPPROTO_TCP, TCP_AO_INFO, ...) might had no chance
of getting used on the wire.
Fixes the following failures, exposed by the previous commit:

The end_server() function only operates in the server thread
and always takes an accept socket instead of a listen socket as
its input argument. To align with this, invert the boolean values
used when calling verify_counters() within the end_server() function.
As a result of this typo, the test didn't correctly check for
the non-symmetrical scenario, where i.e. peer-A uses a key <100:200>
to send data, but peer-B uses another key <105:205> to send its data.
So, in simple words, different keys for TX and RX.

The test sends packets and compares enqueue, transmit and Ack
timestamps with expected values. It installs netem delays to increase
latency between these points.
The test proves flaky in virtual environment (vng). Increase the
delays to reduce variance. Scale measurement tolerance accordingly.
Time sensitive tests are difficult to calibrate. Increasing delays 10x
also increases runtime 10x, for one. And it may still prove flaky at
some rate.

commit 25ae948b44 ("selftests/net: add lib.sh") added net/lib.sh to
contain code shared by tests under net/ and net/forwarding/. However, this
caused issues with selftests from directories other than net/forwarding/,
in particular those under drivers/net/. Those issues were avoided in a
simple way by duplicating some content in commit 2114e83381 ("selftests:
forwarding: Avoid failures to source net/lib.sh").
In order to remove the duplicated content, restore the inclusion of
net/lib.sh from net/forwarding/lib.sh but with the following changes:
* net/lib.sh is imported through the net_forwarding_dir path
The original expression "source ../lib.sh" would look for lib.sh in the
directory above the script file's one, which did not work for tests under
drivers/net/.
* net/lib.sh is added to TEST_INCLUDES
Since net/forwarding/lib.sh now sources net/lib.sh, both of those files
must be exported along with tests which source net/forwarding/lib.sh.

The following code which is part of lib.sh:

if [[ "$relative_path" == "${BASH_SOURCE}" ]]; then
relative_path="."

To avoid this duplication, replace "relative_path" by "net_forwarding_dir",
a new variable defined using dirname.
Furthermore, to avoid the potential confusion about what "relative_path" is
about (cwd, test script directory or test library directory), define
"net_forwarding_dir" as the absolute path to net/forwarding/.

The dsa tests which are symlinks of tests from net/forwarding/ (like
tc_actions.sh) become regular files after export (because `rsync
--copy-unsafe-links` is used) and expect to source lib.sh
(net/forwarding/lib.sh) from the same directory.
In the last patch of this series, net/forwarding/lib.sh will source lib.sh
from its parent directory (ie. net/lib.sh). This would not work for dsa
tests because net/lib.sh is not present under drivers/net/.
Since the tests in net/forwarding/ are not meant to be copied and run from
another directory, as a preparation for that last patch, replace the test
symlinks by a wrapper script which runs the original tests under
net/forwarding/. Following from that, the links to shared library scripts
in dsa/ are no longer used so remove them and add all the original files
needed from parent directories to TEST_INCLUDES.

Some tests written in bash source other files in a parent directory. For
example, drivers/net/bonding/dev_addr_lists.sh sources
net/forwarding/lib.sh. If a subset of tests is exported and run outside the
source tree (for example by using `make -C tools/testing/selftests gen_tar
TARGETS="drivers/net/bonding"`), these other files must be made available
as well.
Commit ae108c48b5 ("selftests: net: Fix cross-tree inclusion of scripts")
addressed this problem by symlinking and copying the sourced files but this
only works for direct dependencies. Commit 25ae948b44 ("selftests/net:
add lib.sh") changed net/forwarding/lib.sh to source net/lib.sh. As a
result, that latter file must be included as well when the former is
exported. This was not handled and was reverted in commit 2114e83381
("selftests: forwarding: Avoid failures to source net/lib.sh"). In order to
allow reinstating the inclusion of net/lib.sh from net/forwarding/lib.sh,
add a mechanism to list dependent files in a new Makefile variable and
export them. This allows sourcing those files using the same expression
whether tests are run in-tree or exported.
Dependencies are not resolved recursively so transitive dependencies must
be listed in TEST_INCLUDES. For example, if net/forwarding/lib.sh sources
net/lib.sh; the Makefile related to a test that sources
net/forwarding/lib.sh from a parent directory must list:
TEST_INCLUDES := \
../../../net/forwarding/lib.sh \
../../../net/lib.sh

One of the test cases in the test_bridge_backup_port.sh selftest relies
on a matchall classifier to drop unrelated traffic so that the Tx drop
counter on the VXLAN device will only be incremented as a result of
traffic generated by the test.
However, the configuration option for the matchall classifier is
missing from the configuration file which might explain the failures we
see in the netdev CI [1].
Fix by adding CONFIG_NET_CLS_MATCHALL to the configuration file.

kselftest/seccomp: Use kselftest output functions for benchmark
selftests/livepatch: fix and refactor new dmesg message code
selftests/rseq: Do not skip !allowed_cpus for mm_cid
The seccomp benchmark test makes a number of checks on the performance it
measures and logs them to the output but does so in a custom format which
none of the automated test runners understand meaning that the chances that
anyone is paying attention are slim. Let's additionally log each result in
KTAP format so that automated systems parsing the test output will see each
comparison as a test case. The original logs are left in place since they
provide the actual numbers for analysis.
As part of this rework the flow for the main program so that when we skip
tests we still log all the tests we skip, this is because the standard KTAP
headers and footers include counts of the number of expected and run tests.

The livepatching kselftests rely on comparing expected vs. observed
dmesg output. After each test, new dmesg entries are determined by the
'comm' utility comparing a saved, pre-test copy of dmesg to post-test
dmesg output.
Alexander reports that the 'comm --nocheck-order -13' invocation used by
the tests can be confused when dmesg entry timestamps vary in magnitude
(ie, "[ 98.820331]" vs. "[ 100.031067]"), in which case, additional
messages are reported as new. The unexpected entries then spoil the
test results.
Instead of relying on 'comm' or 'diff' to determine new testing dmesg
entries, refactor the code:
- pre-test : log a unique canary dmesg entry
- test : run tests, log messages
- post-test : filter dmesg starting from pre-test message

The config file contains a partial kernel configuration to be used by

In net/forwarding/config, many are missing, which manifests as spurious
failures when running the selftests, with messages about unknown device
types, qdisc kinds or classifier actions. Add the missing configurations.
