[PATCH bpf-next v5 0/7] use network helpers, part 5

by Geliang Tang

From: Geliang Tang <tanggeliang(a)kylinos.cn> This patchset uses post_socket_cb and post_connect_cb callbacks of struct network_helper_opts to refactor do_test() in bpf_tcp_ca.c to move dctcp test dedicated code out of do_test() into test_dctcp(). v5: - address Martin's comments in v4 (thanks) - add patch 4, use start_server_str in test_dctcp_fallback too - ASSERT_* is already used in settcpca, use this helper in cc_cb (patch 3) and stg_post_socket_cb (patch 6) - add ASSERT_* in stg_post_socket_cb in patch 6 v4: - address Martin's comments in v3 (thanks). - drop 2 patches, keep "type" as the individual arg to start_server_addr, connect_to_addr and start_server_str. v3: - Add 4 new patches, 1-3 are cleanups. 4 adds a new helper. - address Martin's comments in v2. v2: - rebased on commit "selftests/bpf: Add test for the use of new args in cong_control" Geliang Tang (7): selftests/bpf: Drop struct post_socket_opts selftests/bpf: Add start_server_str helper selftests/bpf: Use post_socket_cb in connect_to_fd_opts selftests/bpf: Use post_socket_cb in start_server_str selftests/bpf: Use start_server_str in do_test in bpf_tcp_ca selftests/bpf: Use connect_to_fd_opts in do_test in bpf_tcp_ca selftests/bpf: Add post_connect_cb callback tools/testing/selftests/bpf/network_helpers.c | 39 +++-- tools/testing/selftests/bpf/network_helpers.h | 9 +- .../selftests/bpf/prog_tests/bpf_tcp_ca.c | 153 +++++++++++++----- .../bpf/prog_tests/sockopt_inherit.c | 2 +- .../bpf/test_tcp_check_syncookie_user.c | 4 +- 5 files changed, 145 insertions(+), 62 deletions(-) -- 2.43.0

[PATCH net 1/2] net/sched: taprio: make q->picos_per_byte available to fill_sched_entry()

by Vladimir Oltean

In commit b5b73b26b3ca ("taprio: Fix allowing too small intervals"), a comparison of user input against length_to_duration(q, ETH_ZLEN) was introduced, to avoid RCU stalls due to frequent hrtimers. The implementation of length_to_duration() depends on q->picos_per_byte being set for the link speed. The blamed commit in the Fixes: tag has moved this too late, so the checks introduced above are ineffective. The q->picos_per_byte is zero at parse_taprio_schedule() -> parse_sched_list() -> parse_sched_entry() -> fill_sched_entry() time. Move the taprio_set_picos_per_byte() call as one of the first things in taprio_change(), before the bulk of the netlink attribute parsing is done. That's because it is needed there. Add a selftest to make sure the issue doesn't get reintroduced.

[PATCH 0/3] selftests/futex: clang-inspired fixes

[PATCH v2] selftests/net: suppress clang's "variable-sized type not at the end" warning

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns that "a variable sized type not at the end of a struct or class is a GNU extension". These cases are not easily changed, because they involve structs that are part of the API. Fortunately, however, the tests seem to be doing just fine (specifically, neither affected test runs any differently with gcc vs. clang builds, on my test system) regardless of the warning. So, all the warning is doing is preventing a clean build of selftests/net. Fix this by suppressing this particular clang warning for the selftests/net suite.
