** Description changed: + [Impact] + Upstream commit d3bec0138bfbe58606fc1d6f57a4cdc1a20218db (bpf: Zero-fill re-used per-cpu map element) was applied to Groovy as part of an upstream stable update. This patch fixes a bpf issue and at the same time adds new selftests to verify these changes. However, the selftests can't be compiled on 5.8 due to missing helper functions that were added only later. The bpf selftest build fails with errors such as: + + /usr/bin/ld: /tmp/autopkgtest.IzBxE1/build.8NX/src/autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/bpf/map_init.test.o: in function `prog_run_insert_elem': + /tmp/autopkgtest.IzBxE1/build.8NX/src/autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/bpf/prog_tests/map_init.c:89: undefined reference to `ASSERT_OK' + + [Fix] + The proposed fix it to partially revert this commit by removing the selftests parts. + + [Testcase] + On a groovy/linux repo: + + $ make -C tools/testing/selftests TARGETS=bpf SKIP_TARGETS= + + [Where problems could occur] + By removing the selftests we could be introducing a regression with the bpf code change which would be likely unoticed during the tests. + + + ==== Original Description ==== + Issue found on 5.8.0-1024.26-azure / 5.8.0-1022.23-oracle Test failed to build, I didn't see any meaningful error message, this might need to be double checked.

I think this is affecting the ubuntu_kernel_selftests as well, as the net test would require the bpf test to be built first.
