H A Dconfigdiff 7c036ed9e0065e852fb1886d9ea97ceb35680e3f Tue Sep 20 09:59:48 CEST 2022 Roberto Sassu <roberto.sassu@huawei.com> selftests/bpf: Add verifier tests for bpf_lookup_*_key() and bpf_key_put()

Add verifier tests for bpf_lookup_*_key() and bpf_key_put(), to ensure that
acquired key references stored in the bpf_key structure are released, that
a non-NULL bpf_key pointer is passed to bpf_key_put(), and that key
references are not leaked.

Also, slightly modify test_verifier.c, to find the BTF ID of the attach
point for the LSM program type (currently, it is done only for TRACING).
