selftests/bpf: Fix some issues for selftest test_xdp_redirect_multi.sh (!118) · Merge requests · Red Hat / centos-stream / src / kernel / centos-stream-9

Hangbin Liu requested to merge liuhangbin/centos-stream-9:bz2008895_xdp_multi into main Nov 09, 2021

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2008895

Jiri reported some issues in test_xdp_redirect_multi.sh. Like the test logs not cleaned after testing. The tcpdump is not terminated cleanly. arp number count may have false positive. And most important, after creating/deleting a lot of interfaces, the interface index may exceed the DEVMAP max entry and cause program xdp_redirect_multi exec failed.

This patch set fixes all these issues.
