[PATCH bpf v2 4/4] selftests/bpf: Fail unbound UDP on sockmap update
From: Michal Luczaj <hidden>
Date: 2026-06-26 20:37:13
Also in:
bpf, linux-kselftest, lkml
Subsystem:
bpf [general] (safe dynamic programs and tools), bpf [selftests] (test runners & infrastructure), kernel selftest framework, the rest · Maintainers:
Alexei Starovoitov, Daniel Borkmann, Andrii Nakryiko, Eduard Zingerman, Kumar Kartikeya Dwivedi, Shuah Khan, Linus Torvalds
sockmap now rejects unbound UDP sockets. Adjust test_maps.
This effectively reverts commit c39aa2159974 ("bpf, selftests: Fix
test_maps now that sockmap supports UDP").
