This patchset implements a change to bpf_setsockopt() which allows ktls enabled sockets to be used with the SOL_TCP level. This is necessary as when ktls is enabled, it changes the function pointer of setsockopt of the socket, which bpf_setsockopt() checks in order to make sure that the socket is a TCP socket. Checking sk_protocol instead of the function pointer will ensure that bpf_setsockopt() with the SOL_TCP level still works on sockets with ktls enabled. The major differences form v2 are: - Add a read() call to make sure that the FIN has arrived. - Remove the dependency on other test's header. The major differences from v1 are: - Test with a IPv6 connect as well. - Use ASSERT_OK() v2: https://lore.kernel.org/bpf/20230124181220.2871611-1-kuifeng@xxxxxxxx/ v1: https://lore.kernel.org/bpf/20230121025716.3039933-1-kuifeng@xxxxxxxx/ Kui-Feng Lee (2): bpf: Check the protocol of a sock to agree the calls to bpf_setsockopt(). selftests/bpf: Calls bpf_setsockopt() on a ktls enabled socket. net/core/filter.c | 2 +- .../selftests/bpf/prog_tests/setget_sockopt.c | 73 +++++++++++++++++++ .../selftests/bpf/progs/setget_sockopt.c | 8 ++ 3 files changed, 82 insertions(+), 1 deletion(-) -- 2.30.2
