From: Martin KaFai Lau Date: Thu, 22 May 2025 21:26:59 +0000 (-0700) Subject: Merge branch 'selftests-bpf-test-sockmap-sockhash-redirection' X-Git-Tag: v6.16-rc1~131^2~14 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=6888a036cfc3d617d0843ecc9bd8504e91fb9de6;p=linux-2.6-block.git Merge branch 'selftests-bpf-test-sockmap-sockhash-redirection' Michal Luczaj says: ==================== selftests/bpf: Test sockmap/sockhash redirection The idea behind this series is to comprehensively test the BPF redirection: BPF_MAP_TYPE_SOCKMAP, BPF_MAP_TYPE_SOCKHASH x sk_msg-to-egress, sk_msg-to-ingress, sk_skb-to-egress, sk_skb-to-ingress x AF_INET, SOCK_STREAM, AF_INET6, SOCK_STREAM, AF_INET, SOCK_DGRAM, AF_INET6, SOCK_DGRAM, AF_UNIX, SOCK_STREAM, AF_UNIX, SOCK_DGRAM, AF_VSOCK, SOCK_STREAM, AF_VSOCK, SOCK_SEQPACKET New module is introduced, sockmap_redir: all supported and unsupported redirect combinations are tested for success and failure respectively. Code is pretty much stolen/adapted from Jakub Sitnicki's sockmap_redir_matrix.c [1]. Usage: $ cd tools/testing/selftests/bpf $ make $ sudo ./test_progs -t sockmap_redir ... Summary: 1/576 PASSED, 0 SKIPPED, 0 FAILED [1]: https://github.com/jsitnicki/sockmap-redir-matrix/blob/main/sockmap_redir_matrix.c Changes in v3: - Drop unrelated changes; sockmap_listen, test_sockmap_listen, doc - Collect tags [Jakub, John] - Introduce BPF verdict programs especially for sockmap_redir [Jiayuan] - Link to v2: https://lore.kernel.org/r/20250411-selftests-sockmap-redir-v2-0-5f9b018d6704@rbox.co Changes in v2: - Verify that the unsupported redirect combos do fail [Jakub] - Dedup tests in sockmap_listen - Cosmetic changes and code reordering - Link to v1: https://lore.kernel.org/bpf/42939687-20f9-4a45-b7c2-342a0e11a014@rbox.co/ ==================== Link: https://patch.msgid.link/20250515-selftests-sockmap-redir-v3-0-a1ea723f7e7e@rbox.co Signed-off-by: Martin KaFai Lau --- 6888a036cfc3d617d0843ecc9bd8504e91fb9de6
