selftests: mptcp: connect: skip if MPTCP is not supported

2023-05-30T11:21:02+00:00

Selftests are supposed to run on any kernels, including the old ones not supporting MPTCP. A new check is then added to make sure MPTCP is supported. If not, the test stops and is marked as "skipped". Note that this check can also mark the test as failed if 'SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES' env var is set to 1: by doing that, we can make sure a test is not being skipped by mistake. A new shared file is added here to be able to re-used the same check in the different selftests we have.

selftests: stop using KSFT_KHDR_INSTALL

2022-07-11T23:23:30+00:00

Stop using the KSFT_KHDR_INSTALL flag as installing the kernel headers from the kselftest Makefile is causing some issues. Instead, rely on the headers to be installed directly by the top-level Makefile "headers_install" make target prior to building kselftest.

selftests: mptcp: validate userspace PM tests by default

2022-07-11T10:31:38+00:00

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.

selftests: mptcp: add inq test case

2021-12-07T19:36:30+00:00

client & server use a unix socket connection to communicate outside of the mptcp connection. This allows the consumer to know in advance how many bytes have been (or will be) sent by the peer. This allows stricter checks on the bytecounts reported by TCP_INQ cmsg. Suggested-by: Mat Martineau Signed-off-by: Florian Westphal Signed-off-by: Mat Martineau Signed-off-by: Jakub Kicinski

selftests: mptcp: add mptcp getsockopt test cases

2021-09-18T13:20:01+00:00

Add a test program that retrieves the three info types: 1. mptcp meta information 2. tcp info for subflow 3. subflow endpoint addresses For all three rudimentary checks are added. 1. Meta information checks that the logical mptcp sequence numbers advance as expected, based on the bytes read (init seq + bytes_received/sent) and the connection state (after close, we should exect 1 extra byte due to FIN). 2. TCP info checks the number of bytes sent/received vs. sums of read/write syscall return values. 3. Subflow endpoint addresses are checked vs. getsockname/getpeername result. Tests for forward compatibility (0-initialisation of output-only fields in mptcp_subflow_data structure) are added as well.

selftests: mptcp: add packet mark test case

2021-04-16T22:23:10+00:00

Extend mptcp_connect tool with SO_MARK support (-M ) and add a test case that checks that the packet mark gets copied to all subflows. This is done by only allowing packets with either skb->mark 1 or 2 via iptables. DROP rule packet counter is checked; if its not zero, print an error message and fail the test case.
