5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Tony Ambardar <tony.ambardar@xxxxxxxxx> [ Upstream commit bae9a5ce7d3a9b3a9e07b31ab9e9c58450e3e9fd ] The GNU version of 'struct tcphdr' with member 'doff' is not exposed by musl headers unless _GNU_SOURCE is defined. Add this definition to fix errors seen compiling for mips64el/musl-libc: In file included from kfree_skb.c:2: kfree_skb.c: In function 'on_sample': kfree_skb.c:45:30: error: 'struct tcphdr' has no member named 'doff' 45 | if (CHECK(pkt_v6->tcp.doff != 5, "check_tcp", | ^ Fixes: 580d656d80cf ("selftests/bpf: Add kfree_skb raw_tp test") Signed-off-by: Tony Ambardar <tony.ambardar@xxxxxxxxx> Signed-off-by: Andrii Nakryiko <andrii@xxxxxxxxxx> Link: https://lore.kernel.org/bpf/e2d8cedc790959c10d6822a51f01a7a3616bea1b.1721713597.git.tony.ambardar@xxxxxxxxx Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- tools/testing/selftests/bpf/prog_tests/kfree_skb.c | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/testing/selftests/bpf/prog_tests/kfree_skb.c b/tools/testing/selftests/bpf/prog_tests/kfree_skb.c index 42c3a3103c262..a37b1d663f964 100644 --- a/tools/testing/selftests/bpf/prog_tests/kfree_skb.c +++ b/tools/testing/selftests/bpf/prog_tests/kfree_skb.c @@ -1,4 +1,5 @@ // SPDX-License-Identifier: GPL-2.0 +#define _GNU_SOURCE #include <test_progs.h> #include <network_helpers.h> -- 2.43.0
