bpf: test_maps: cleanup sockmaps when test ends
Bug: BPF programs and maps related to sockmaps test exist in memory even after test_maps ends. This patch fixes it as a short term workaround (sockmap kernel side needs real fixing) by empyting sockmaps when test ends. Fixes: 6f6d33f3b3d0f ("bpf: selftests add sockmap tests") Signed-off-by: Prashant Bhole <bhole_prashant_q7@lab.ntt.co.jp> [ daniel: Note on workaround. ] Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
