selftests: mptcp: print test results with colors To unify the output formats of all test scripts, this patch adds four more helpers: mptcp_lib_pr_ok() mptcp_lib_pr_skip() mptcp_lib_pr_fail() mptcp_lib_pr_info() to print out [ OK ], [SKIP], [FAIL] and 'INFO: ' with colors. Use them in all scripts to print the "ok/skip/fail/info' using the same 'format'. Having colors helps to quickly identify issues when looking at a long list of output logs and results. Note that now all print the same keywords, which was not the case before, but it is good to uniform that.

Here, two categories of warnings are now ignored: - SC2317: Command appears to be unreachable. The cleanup() function is invoked indirectly via the EXIT trap. - SC2086: Double quote to prevent globbing and word splitting. This is recommended, but the current usage is correct and there is no need to do all these modifications to be compliant with this rule. For the modifications: - SC2034: ksft_skip appears unused. - SC2004: $/${} is unnecessary on arithmetic variables. Now this script is shellcheck (0.9.0) compliant. We can easily spot new issues.

selftests: mptcp: simult flows: format subtests results in TAP The current selftests infrastructure formats the results in TAP 13. This version doesn't support subtests and only the end result of each selftest is taken into account. It means that a single issue in a subtest of a selftest containing multiple subtests forces the whole selftest to be marked as failed. It also means that subtests results are not tracked by CIs executing selftests. MPTCP selftests run hundreds of various subtests. It is then important to track each of them and not one result per selftest. It is particularly interesting to do that when validating stable kernels with the last version of the test suite: tests might fail because a feature is not supported but the test didn't skip that part. In this case, if subtests are not tracked, the whole selftest will be marked as failed making the other subtests useless because their results are ignored. This patch formats subtests results in TAP in simult_flows.sh selftest.

Even on (virtual) link-speed-bound tests, debug kernel can slow down the transfer enough to cause sporadic test failures. Instead of unconditionally raising the maximum allowed run-time, tweak when the running kernel is a debug one, and use some simple/ rough heuristic to guess such scenarios. Note: this intentionally avoids looking for /boot/config-<version> as the latter file is not always available in our reference CI environments.

selftests: mptcp: more stable simult_flows tests Currently the simult_flows.sh self-tests are not very stable, especially when running on slow VMs. The tests measure runtime for transfers on multiple subflows and check that the time is near the theoretical maximum. The current test infra introduces a bit of jitter in test runtime, due to multiple explicit delays. Additionally the runtime is measured by the shell script wrapper. On a slow VM, the script overhead is measurable and subject to relevant jitter. One solution to make the test more stable would be adding more slack to the expected time; that could possibly hide real regressions. Instead move the measurement inside the command doing the transfer, and drop most unneeded sleeps.

selftests: mptcp: launch mptcp_connect with timeout 'mptcp_connect' already has a timeout for poll() but in some cases, it is not enough. With "timeout" tool, we will force the command to fail if it doesn't finish on time. Thanks to that, the script will continue and display details about the current state before marking the test as failed. Displaying this state is very important to be able to understand the issue. Best to have our CI reporting the issue than just "the test hanged". Note that in mptcp_connect.sh, we were using a long timeout to validate the fact we cannot create a socket if a sysctl is set. We don't need this timeout. In diag.sh, we want to send signals to mptcp_connect instances that have been started in the netns. But we cannot send this signal to 'timeout' otherwise that will stop the timeout and messages telling us SIGUSR1 has been received will be printed. Instead of trying to find the right PID and storing them in an array, we can simply use the output of 'ip netns pids' which is all the PIDs we want to send signal to.

MPTCP will try to push frames on such subflow and will fail. Pending frames will be pushed only after receiving a window update on a subflow with some wspace available. Overall the above could lead to suboptimal aggregate bandwidth usage. Instead, we should try to push pending frames as soon as the subflow reaches both conditions mentioned above. We can finally enable self-tests with asymmetric links, as the above makes them finally pass.

selftests: mptcp: interpret \n as a new line In case of errors, this message was printed: (...) balanced bwidth with unbalanced delay 5233 max 5005 [ fail ] client exit code 0, server 0 \nnetns ns3-0-EwnkPH socket stat for 10003: (...) Obviously, the idea was to add a new line before the socket stat and not print "\nnetns". The commit 8b974778f998 ("selftests: mptcp: interpret \n as a new line") is very similar to this one. But the modification in simult_flows.sh was missed because this commit above was done in parallel to one here below.

mptcp: simult flow self-tests Add a bunch of test-cases for multiple subflow xmit: create multiple subflows simulating different links condition via netem and verify that the msk is able to use completely the aggregated bandwidth.
