selftests: net: Fix O=dir builds

2022-12-09T03:26:18Z

The BPF Makefile in net/bpf did incorrect path substitution for O=dir builds, e.g. make O=/tmp/kselftest headers make O=/tmp/kselftest -C tools/testing/selftests would fail in selftest builds [1] net/ with clang-16: error: no such file or directory: 'kselftest/net/bpf/nat6to4.c' clang-16: error: no input files Add a pattern prerequisite and an order-only-prerequisite (for creating the directory), to resolve the issue.

selftests: net: Add cross-compilation support for BPF programs

2022-11-22T12:49:22Z

The selftests/net does not have proper cross-compilation support, and does not properly state libbpf as a dependency. Mimic/copy the BPF build from selftests/bpf, which has the nice side-effect that libbpf is built as well.

bpf_helpers.h has been moved to tools/lib/bpf since 5.10, so add more including path.

selftests net: add UDP GRO fraglist + bpf self-tests

2022-05-09T09:48:49Z

When NET_F_F_GRO_FRAGLIST is enabled and bpf_skb_change_proto is used, check if udp packets and tcp packets are successfully delivered to user space. If wrong udp packets are delivered, udpgso_bench_rx will exit with "Initial byte out of range" Signed-off-by: Maciej enczykowski Signed-off-by: Lina Wang Signed-off-by: David S. Miller
