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: fix the return value for UDP GRO test

2021-01-06T00:59:21Z

The udpgro.sh will always return 0 (unless the bpf selftest was not build first) even if there are some failed sub test-cases. Therefore the kselftest framework will report this case is OK. Check and return the exit status of each test to make it easier to spot real failures. Signed-off-by: Po-Hsu Lin Signed-off-by: David S. Miller

selftests: fixes for UDP GRO

2019-03-01T19:24:00Z

The current implementation for UDP GRO tests is racy: the receiver may flush the RX queue while the sending is still transmitting and incorrectly report RX errors, with a wrong number of packet received. Add explicit timeouts to the receiver for both connection activation (first packet received for UDP) and reception completion, so that in the above critical scenario the receiver will wait for the transfer completion.

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.
