2024-03-04selftests: mptcp: diag: return KSFT_FAIL not test_cntGeliang Tang
The test counter 'test_cnt' should not be returned in diag.sh, e.g. what if only the 4th test fail? Will do 'exit 4' which is 'exit ${KSFT_SKIP}', the whole test will be marked as skipped instead of 'failed'! So we should do ret=${KSFT_FAIL} instead.

2024-02-26selftests: mptcp: lib: catch duplicated subtest entriesMatthieu Baerts (NGI0)
It is important to have a unique (sub)test name in TAP, because some CI environments drop tests with duplicated name. When adding a new subtest entry, an error message is printed in case of duplicated entries. If there were duplicated entries and if all features were expected to work, the script exits with an error at the end, after having printed all subtests in the TAP format. Thanks to that, the MPTCP CI will catch such issues early.

The mptcp diag interface already experienced a few locking bugs that lockdep and appropriate coverage have detected in advance. Let's add a test-case triggering the relevant code path, to prevent similar issues in the future. Be careful to cope with very slow environments. Note that we don't need an explicit timeout on the mptcp_connect subprocess to cope with eventual bug/hang-up as the final cleanup terminating the child processes will take care of that.

It is important to have a unique (sub)test name in TAP, because some CI environments drop tests with duplicated names. Some subtests from the userspace_pm selftest had the same names. That's because different subflows are created (and deleted) between the same pair of IP addresses. Simply adding the destination port in the name is then enough to have different names, because the destination port is always different. Note that adding such info takes a bit more space, so we need to increase a bit the width to print the name, simply to keep all the '[ OK ]' aligned as before.

This is not what we expected. The correct logic here should be: if mptcp_subflow_send_ack is not a global function in /proc/kallsyms, do these MPC backups tests.

2023-11-29selftests: mptcp: add mptcp_lib_wait_local_port_listenGeliang Tang
To avoid duplicated code in different MPTCP selftests, we can add and use helpers defined in mptcp_lib.sh. wait_local_port_listen() helper is defined in diag.sh, mptcp_connect.sh, mptcp_join.sh and simult_flows.sh, export it into mptcp_lib.sh and rename it with mptcp_lib_ prefix. Use this new helper in all these scripts. Note: We only have IPv4 connections in this helper, not looking at IPv6 (tcp6) but that's OK because we only have IPv4 connections here in diag.sh.

Same init_rng() in both tests. The function reads /dev/urandom to initialize srand(). In case of failure, it falls back onto the entropy in the uninitialized variable. Not sure if this is on purpose. But failure reading urandom should be rare, so just fail hard. While at it, convert to getrandom(). Which man 4 random suggests is simpler and more robust. mptcp_inq.c:525:6: mptcp_connect.c:1131:6: error: variable 'foo' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] Fixes: 048d19d444be ("mptcp: add basic kselftest for mptcp") Fixes: b51880568f20 ("selftests: mptcp: add inq test case") Cc: Florian Westphal <fw@strlen.de> Signed-off-by: Willem de Bruijn <willemb@google.com> ---- When input is randomized because this is expected to meaningfully explore edge cases, should we also add 1. logging the random seed to stdout and 2. adding a command line argument to replay from a specific seed I can do this in net-next, if authors find it useful in this case.

Note that the same check is repeated explicitly in the same test-case, with the correct expectation and pass successfully.

The second input parameter of 'wait_rm_addr/sf $1 1' is misused. If it's 1, wait_rm_addr/sf will never break, and will loop ten times, then 'wait_rm_addr/sf' equals to 'sleep 1'. This delay time is too long, which can sometimes make the tests fail. A better way to use wait_rm_addr/sf is to use rm_addr/sf_count to obtain the current value, and then pass into wait_rm_addr/sf.
