selftests: tls: add test for short splice due to full skmsg

2025-10-16T00:41:46Z

We don't have a test triggering a partial splice caused by a full skmsg. Add one, based on a program by Jann Horn. Use MAX_FRAGS=48 to make sure the skmsg will be full for any allowed value of CONFIG_MAX_SKB_FRAGS (17..45).

selftests: net: tls: add tests for cmsg vs MSG_MORE

2025-10-16T00:41:45Z

We don't have a test to check that MSG_MORE won't let us merge records of different types across sendmsg calls. Add new tests that check: - MSG_MORE is only allowed for DATA records - a pending DATA record gets closed and pushed before a non-DATA record is processed Signed-off-by: Sabrina Dubroca Link: https://patch.msgid.link/b34feeadefe8a997f068d5ed5617afd0072df3c0.1760432043.git.sd@queasysnail.net Signed-off-by: Jakub Kicinski

selftests: tls: add tests for zero-length records

2025-08-21T14:52:31Z

Test various combinations of zero-length records. Unfortunately, kernel cannot be coerced into producing those, so hardcode the ciphertext messages in the test. Reviewed-by: Sabrina Dubroca Link: https://patch.msgid.link/20250820021952.143068-2-kuba@kernel.org Signed-off-by: Jakub Kicinski

selftests: tls: make the new data_steal test less flaky

2025-08-16T01:07:27Z

The CI has hit a couple of cases of: RUN global.data_steal ... tls.c:2762:data_steal:Expected recv(cfd, buf2, sizeof(buf2), MSG_DONTWAIT) (20000) == -1 (-1) data_steal: Test terminated by timeout FAIL global.data_steal Looks like the 2msec sleep is not long enough. Make the sleep longer, and then instead of second sleep wait for the thieving process to exit. That way we can be sure it called recv() before us. While at it also avoid trying to steal more than a record, this seems to be causing issues in manual testing as well.

selftests: tls: check that disconnect does nothing

2025-04-08T09:38:49Z

"Inspired" by syzbot test, pre-queue some data, disconnect() and try to receive(). This used to trigger a warning in TLS's strp. Now we expect the disconnect() to have almost no effect.
