Bug Description

[Impact]

The tls bidir test from the network kselftests fails with the ChaCha cipher:

 # RUN tls.12_chacha.bidir ...
 # tls.c:845:bidir:Expected ret (-1) == 0 (0)
 # bidir: Test terminated by assertion
 # FAIL tls.12_chacha.bidir

This is a problem with the test. The test fixture setup configures tls in one direction on the test socket pair according to the cipher being tested. The test case configures tls in the other direction, however it always configures for GCM regardless of the cipher being tested. When the test cipher is ChaCha the setsockopt() calls fail as the cipher is required to be the same in both directions.

[Test Plan]

Run the tls test from the net kselftests and confirm that the bidir test now passes when the test cipher is ChaCha.

[Where problems could occur]

This is a fix for a test case and should have no user impact. A serious problem in the test case might cause passing test cases to fail or prevent subsequent test cases from running. Any such issues should be caught during testing in -proposed before releasing kernels to users.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-hirsute' to 'verification-done-hirsute'. If the problem still exists, change the tag 'verification-needed-hirsute' to 'verification-failed-hirsute'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

Confirmed to be fixed with the current SRU cycle's hirsute/linux kernel:

Before (5.11.0-24.25):
# # RUN tls.12_chacha.bidir ...
# # tls.c:845:bidir:Expected ret (-1) == 0 (0)
# # bidir: Test terminated by assertion
# # FAIL tls.12_chacha.bidir
# not ok 123 tls.12_chacha.bidir

Latest kernel (5.11.0-26.28):
# # RUN tls.12_chacha.bidir ...
# # OK tls.12_chacha.bidir
# ok 123 tls.12_chacha.bidir

This was not part of the main focal kernel. I assume the verification was somehow triggered by the hwe-5.11 kernel. I have just checked the selftest results there and "tls" was not failing.
