selftests/net: fix missing xdp_dummy

2022-11-18T12:01:14Z

After commit afef88e65554 ("selftests/bpf: Store BPF object files with .bpf.o extension"), we should use xdp_dummy.bpf.o instade of xdp_dummy.o. In addition, use the BPF_FILE variable to save the BPF object file name, which can be better identified and modified.

selftests/net: give more time to udpgro bg processes to complete startup

2022-11-04T10:10:59Z

In some conditions, background processes in udpgro don't have enough time to set up the sockets. When foreground processes start, this results in the test failing with "./udpgso_bench_tx: sendmsg: Connection refused". For instance, this happens from time to time on a Qualcomm SA8540P SoC running CentOS Stream 9. To fix this, increase the time given to background processes to complete the startup before foreground processes start. Signed-off-by: Adrien Thierry Signed-off-by: David S. Miller

selftests/net: fix section name when using xdp_dummy.o

2022-07-02T03:16:02Z

Since commit 8fffa0e3451a ("selftests/bpf: Normalize XDP section names in selftests") the xdp_dummy.o's section name has changed to xdp. But some tests are still using "section xdp_dummy", which make the tests failed. Fix them by updating to the new section name.

selftests: add functionals test for UDP GRO

2018-11-08T00:23:05Z

Extends the existing udp programs to allow checking for proper GRO aggregation/GSO size, and run the tests via a shell script, using a veth pair with XDP program attached to trigger the GRO code path. rfc v3 -> v1: - use ip route to attach the xdp helper to the veth rfc v2 -> rfc v3: - add missing test program options documentation - fix sporatic test failures (receiver faster than sender) Signed-off-by: Paolo Abeni Signed-off-by: David S.

selftests: add some benchmark for UDP GRO

2018-11-08T00:23:05Z

Run on top of veth pair, using a dummy XDP program to enable the GRO. rfc v3 -> v1: - use ip route to attach the xdp helper to the veth Signed-off-by: Paolo Abeni Signed-off-by: David S. Miller
