From 7c036ed9e0065e852fb1886d9ea97ceb35680e3f Mon Sep 17 00:00:00 2001 From: Roberto Sassu Date: Tue, 20 Sep 2022 09:59:48 +0200 Subject: 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).
