Hi stable team,
Building BPF selftests on 5.10.186 currently causes the following compile error:
$ make -C tools/testing/selftests/bpf ... BINARY test_verifier In file included from /usr/src/linux-5.10.186/tools/testing/selftests/bpf/verifier/tests.h:59, from test_verifier.c:355: /usr/src/linux-5.10.186/tools/testing/selftests/bpf/verifier/ref_tracking.c:935:10: error: 'struct bpf_test' has no member named 'fixup_map_ringbuf'; did you mean 'fixup_map_in_map'? 935 | .fixup_map_ringbuf = { 11 }, | ^~~~~~~~~~~~~~~~~ | fixup_map_in_map
The problem was introduced by commit f4b8c0710ab6 ("selftests/bpf: Add verifier test for release_reference()") in your tree.
Seems like at least commit 4237e9f4a962 ("selftests/bpf: Add verifier test for PTR_TO_MEM spill") is required for the build to succeed.
I previously reported this but things probably fell through the cracks: https://lore.kernel.org/stable/CAN+4W8iMcwwVjmSekZ9txzZNxOZ0x98nBXo4cEoTU9G2...
Thanks! Lorenz
