[PATCH bpf 0/2] selftests/bpf: add missing CONFIG values to test config

by Alan Maguire

Selftests "config" file is intended to represent the config required to run the tests; a few values are missing for the BPF selftests and these can result in test failures due to missing helpers etc. Add the missing values as they will help document the config needed for a clean BPF selftests run.

[PATCH v3] Kernel selftests: Add check if TPM devices are supported

by Nikita Sobolev

TPM2 tests set uses /dev/tpm0 and /dev/tpmrm0 without check if they are available. In case, when these devices are not available test fails, but expected behaviour is skipped test.
