The test runs well but is currently not integrated in test_progs, which prevents it from being run automatically in the CI infrastructure. Rewrite it as a C test relying on libbpf to allow running it in the CI infrastructure. The new code brings up the same network infrastructure and reuses the same eBPF programs as test_xdp_veth.sh, for which skeletons are already generated by the bpf tests makefile. Signed-off-by: Alexis Lothoré --- The new code has been tested in an aarch64 qemu instance: Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED I have also checked that some minor alterations in the network configuration (altering the redirect map, or not loading one of the xdp programs) make the test fail. On my testing setup, the test takes a bit more than 3 seconds to run on average. --- .../selftests/bpf/prog_tests/test_xdp_veth.c | 234 +++++++++++++++++++++ 1 file changed, 234 insertions(+) diff --git a/tools/testing/selftests/bpf/prog_tests/test_xdp_veth.c b/tools/testing/selftests/bpf/prog_tests/test_xdp_veth.c new file mode 100644 index 000000000000..40d85aece984 --- /dev/null +++ b/tools/testing/selftests/bpf/prog_tests/test_xdp_veth.c @@ -0,0 +1,234 @@ +// SPDX-License-Identifier: GPL-2.0 +/** + * Create 3 namespaces with 3 veth peers, and + * forward packets in-between using native XDP + * + * XDP_TX + * NS1(veth11) NS2(veth22) NS3(veth33) + * | | | + * | | | + * (veth1, (veth2, (veth3, + * id:111) id:122) id:133) + * ^ | ^ | ^ | + * | | XDP_REDIRECT | | XDP_REDIRECT | | + * | ------------------ ------------------ | + * ----------------------------------------- + * XDP_REDIRECT + */ + +#define _GNU_SOURCE +#include +#include "test_progs.h" +#include "network_helpers.h" +#include "xdp_dummy.skel.h" +#include "xdp_redirect_map.skel.h" +#include "xdp_tx.skel.h" + +#define VETH_PAIRS_COUNT 3 +#define NS_NAME_MAX_LEN 16 +#define NS_SUFFIX_LEN 6 +#define VETH_NAME_MAX_LEN 16 +#define IP_SRC "10.1.1.11" +#define IP_DST "10.1.1.33" +#define IP_CMD_MAX_LEN 128 + +struct skeletons { + struct xdp_dummy *xdp_dummy;
