Subject: [PATCH bpf-next 05/43] selftests/bpf: prog_tests entry point for migrated test_verifier tests
Date: Sat, 25 Mar 2023 04:54:46 +0200 [thread overview]
Message-ID: <20230325025524.144043-6-eddyz87@gmail.com> (raw)
In-Reply-To: <20230325025524.144043-1-eddyz87@gmail.com>
prog_tests/verifier.c would be used as a host for verifier/*.c tests
migrated to use inline assembly and run from test_progs.
The run_test_aux() function mimics the test_verifier behavior
dropping CAP_SYS_ADMIN upon entry.
