Subject[PATCH stable 5.15 0/1] Fix bpf selftest build failure - error: 'struct bpf_test' has no member named 'fixup_kfunc_btf_id'
Date
The bpf selftest build will fail on the stable 5.15 tree with:

CC test_stub.o
BINARY test_verifier
In file included from /home/ubuntu/linux/tools/testing/selftests/bpf/verifier/tests.h:21,
from test_verifier.c:432:
/home/ubuntu/linux/tools/testing/selftests/bpf/verifier/calls.c:124:10: error: 'struct bpf_test' has no member named 'fixup_kfunc_btf_id'
124 | .fixup_kfunc_btf_id = {
| ^~~~~~~~~~~~~~~~~~
/home/ubuntu/linux/tools/testing/selftests/bpf/verifier/calls.c:124:9: warning: braces around scalar initializer
124 | .fixup_kfunc_btf_id = {
| ^

This is because of the fixup_kfunc_btf_id member in struct bpf_test
added in commit 13c6a37d40 ("selftests/bpf: Add test for reg2btf_ids
out of bounds access") from upstream.

We will need commit 0201b80772 ("selftests/bpf: Add test_verifier
support to fixup kfunc call insns") from upstream to solve this build
issue. Some backport work is needed for the 5.15 tree to skip
fixup_map_timer related changes, which came from commit e60e6962c5
("selftests/bpf: Add tests for restricted helpers").
