selftests/bpf: Add a selftest for the tracing bpf_get_socket_cookieThis builds up on the existing socket cookie test which checks whetherthe bpf_get_socket_cookie helpers provide the same value incgroup/connect6 and sockops programs for a socket created by theuserspace part of the test.Instead of having an update_cookie sockops program tag a socket localstorage with 0xFF, this uses both an update_cookie_sockops program andan update_cookie_tracing program which succesively tag the socket with0x0F and then 0xF0.Signed-off-by: Florent Revest Signed-off-by: Alexei Starovoitov Acked-by: KP Singh Link: https://lore.kernel.org/bpf/20210210111406.785541-5-revest@chromium.org List of files: /linux-6.15/tools/testing/selftests/bpf/prog_tests/socket_cookie.c

61f8c9c8 - selftests/bpf: Integrate the socket_cookie test to test_progs

selftests/bpf: Integrate the socket_cookie test to test_progsCurrently, the selftest for the BPF socket_cookie helpers is built andrun independently from test_progs. It's easy to forget and hard tomaintain.This patch moves the socket cookies test into prog_tests/ and vastlysimplifies its logic by:- rewriting the loading code with BPF skeletons- rewriting the server/client code with network helpers- rewriting the cgroup code with test__join_cgroup- rewriting the error handling code with CHECKsSigned-off-by: Florent Revest Signed-off-by: Alexei Starovoitov Acked-by: KP Singh Acked-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20210210111406.785541-3-revest@chromium.org List of files: /linux-6.15/tools/testing/selftests/bpf/prog_tests/socket_cookie.c
