Public bug reported:
Sru justification
[Impact]
Upstream v5.15.139 (#lp2049432) brought commit "selftests/bpf: Test tail call
counting with bpf2bpf and data on stack" that affects one of the bpf kselftests.
because LIBBPF_OPTS macro does not exists, it does not compile. Error below.
[Fix]
Cherry-pick commit "libbpf: Rename DECLARE_LIBBPF_OPTS into LIBBPF_OPTS"
[Test]
This should be solved soon, but compileselftests debian rule does not compile
bpf selftests.
I tested it by using our regression testing tooling, but same results can be
achieved by running:
$ make -C linux/tools/testing/selftests TARGETS=bpf SKIP_TARGETS= clean all
KDIR=/usr/src/linux-headers-5.15.0-<verson>-generic
from the linux tree directory
Without the fix, it fails to compile:
