2023-04-20selftests: mptcp: userspace pm: uniform verify eventsMatthieu Baerts1-0/+2
commit 711ae788cbbb82818531b55e32b09518ee09a11a upstream. Simply adding a "sleep" before checking something is usually not a good idea because the time that has been picked can not be enough or too much. The best is to wait for events with a timeout. In this selftest, 'sleep 0.5' is used more than 40 times. It is always used before calling a 'verify_*' function except for this verify_listener_events which has been added later. At the end, using all these 'sleep 0.5' seems to work: the slow CIs don't complain so far. Also because it doesn't take too much time, we can just add two more 'sleep 0.5' to uniform what is done before calling a 'verify_*' function. For the same reasons, we can also delay a bigger refactoring to replace all these 'sleep 0.5' by functions waiting for events instead of waiting for a fix time and hope for the best.

2023-02-08selftests: mptcp: stop tests earlierMatthieu Baerts1-4/+10
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.

2023-02-08selftests: mptcp: allow more slack for slow test-casePaolo Abeni1-2/+8
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.

2023-01-14selftests: mptcp: userspace: validate v4-v6 subflows mixMatthieu Baerts1-0/+47
MPTCP protocol supports having subflows in both IPv4 and IPv6. In Linux, it is possible to have that if the MPTCP socket has been created with AF_INET6 family without the IPV6_V6ONLY option. Here, a new IPv4 subflow is being added to the initial IPv6 connection, then being removed using Netlink commands.

2022-11-30selftests: mptcp: mptfo Initiator/ListenerDmytro Shytyi2-42/+150
This patch first adds TFO support in mptcp_connect.c. This can be enabled via a new option: -o MPTFO. Once enabled, the TCP_FASTOPEN socket option is enabled for the server side and a sendto() with MSG_FASTOPEN is used instead of a connect() for the client side. Note that the first SYN has a limit of bytes it can carry. In other words, it is allowed to send less data than the provided one. We then need to track more status info to properly allow the next sendmsg() starting from the next part of the data to send the rest. Also in TFO scenarios, we need to completely spool the partially xmitted buffer -- and account for that -- before starting sendfile/mmap xmit, otherwise the relevant tests will fail.

The new script was not listed in the programs to test. By consequence, some CIs running MPTCP selftests were not validating these new tests. Note that MPTCP CI was validating it as it executes all .sh scripts from 'tools/testing/selftests/net/mptcp' directory.

The mentioned test measures the transfer run-time to verify that the user-space program is able to use the full aggregate B/W. 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.

In a few MPTCP selftest tools, gcc 12 complains that the 'sock' variable might be used uninitialized. This is a false positive because the only code path that could lead to uninitialized access is where getaddrinfo() fails, but the local xgetaddrinfo() wrapper exits if such a failure occurs. Initialize the 'sock' variable anyway to allow the tools to build with gcc 12.

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.
