selftests/bpf: Fix bpf_nf failure upon test rerun
Alexei reported:
After fast forwarding bpf-next today bpf_nf test started to fail when
run twice:
$ ./test_progs -t bpf_nf
#17 bpf_nf:OK
Summary: 1/10 PASSED, 0 SKIPPED, 0 FAILED
$ ./test_progs -t bpf_nf
All error logs:
test_bpf_nf_ct:PASS:test_bpf_nf__open_and_load 0 nsec
test_bpf_nf_ct:PASS:iptables-legacy -t raw -A PREROUTING -j CONNMARK
--set-mark 42/0 0 nsec
(network_helpers.c:102: errno: Address already in use) Failed to bind socket
test_bpf_nf_ct:FAIL:start_server unexpected start_server: actual -1 < expected 0
#17/1 bpf_nf/xdp-ct:FAIL
test_bpf_nf_ct:PASS:test_bpf_nf__open_and_load 0 nsec
test_bpf_nf_ct:PASS:iptables-legacy -t raw -A PREROUTING -j CONNMARK
--set-mark 42/0 0 nsec
(network_helpers.c:102: errno: Address already in use) Failed to bind socket
test_bpf_nf_ct:FAIL:start_server unexpected start_server: actual -1 < expected 0
#17/2 bpf_nf/tc-bpf-ct:FAIL
#17 bpf_nf:FAIL
Summary: 0/8 PASSED, 0 SKIPPED, 1 FAILED
I was able to locally reproduce as well. Rearrange the connection teardown
so that the client closes its connection first so that we don't need to
linger in TCP time-wait.
Fixes: e81fbd4c1ba7 ("selftests/bpf: Add existing connection bpf_*_ct_lookup() test")
