ipv4: Use dscp_t in struct fib_alias
Use the new dscp_t type to replace the fa_tos field of fib_alias. This ensures ECN bits are ignored and makes the field compatible with the fc_dscp field of struct fib_config. Converting old *tos variables and fields to dscp_t allows sparse to flag incorrect uses of DSCP and ECN bits. This patch is entirely about type annotation and shouldn't change any existing behaviour.

Define struct mptcp_sock in bpf_tcp_helpers.h, use bpf_skc_to_mptcp_sock to get the msk socket in progs/mptcp_sock.c and store the infos in socket_storage_map. Get the infos from socket_storage_map in prog_tests/mptcp.c. Add a new function verify_msk() to verify the infos of MPTCP socket, and rename verify_sk() to verify_tsk() to verify TCP socket only. v2: Add CONFIG_MPTCP check for clearer error messages v4: - use ASSERT_* instead of CHECK_FAIL (Andrii) - drop bpf_mptcp_helpers.h (Andrii) v5: - some 'ASSERT_*' were replaced in the next commit by mistake. - Drop CONFIG_MPTCP (Martin) - Use ASSERT_EQ (Andrii) Signed-off-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Matthieu Baerts <matthieu.baerts@tessares.net> Link: https://lore.kernel.org/bpf/20220519233016.105670-5-mathew.j.martineau@linux.intel.com 2022-05-20selftests/bpf: Add MPTCP test baseNicolas Rybowski This patch adds a base for MPTCP specific tests. It is currently limited to the is_mptcp field in case of plain TCP connection because there is no easy way to get the subflow sk from a msk in userspace. This implies that we cannot lookup the sk_storage attached to the subflow sk in the sockops program. v4: - add copyright 2022 (Andrii) - use ASSERT_* instead of CHECK_FAIL (Andrii) - drop SEC("version") (Andrii) - use is_mptcp in tcp_sock, instead of bpf_tcp_sock (Martin & Andrii) v5: - Drop connect_to_mptcp_fd (Martin) - Use BPF test skeleton (Andrii) - Use ASSERT_EQ (Andrii) - Drop the 'msg' parameter of verify_sk Co-developed-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Nicolas Rybowski <nicolas.rybowski@tessares.net> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Matthieu Baerts <matthieu.baerts@tessares.net> Link: https://lore.kernel.org/bpf/20220519233016.105670-4-mathew.j.martineau@linux.intel.com 2021-08-25bpf: selftests: Add sk_state to bpf_tcp_helpers.hMartin KaFai Lau Add sk_state define to bpf_tcp_helpers.h.

Test Details: 1. BPF Program Checks for changes in IPV6_TCLASS(SOL_IPV6) via setsockopt If the cca for the socket is not cubic do nothing If the newly set value for IPV6_TCLASS is 45 (0x2d) (as per our use-case) then change the cc from cubic to reno 2. User Space Program Creates an AF_INET6 socket and set the cca for that to be "cubic" Attach the program and set the IPV6_TCLASS to 0x2d using setsockopt Verify the cca for the socket changed to reno Signed-off-by: Prankur Gupta <prankgup@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Song Liu <songliubraving@fb.com> Link: https://lore.kernel.org/bpf/20210817224221.3257826-3-prankgup@fb.com 2021-03-26bpf: selftests: Bpf_cubic and bpf_dctcp calling kernel functionsMartin KaFai Lau This patch removes the bpf implementation of tcp_slow_start() and tcp_cong_avoid_ai(). Instead, it directly uses the kernel implementation. It also replaces the bpf_cubic_undo_cwnd implementation by directly calling tcp_reno_undo_cwnd(). bpf_dctcp also directly calls tcp_reno_cong_avoid() instead.
