Subject: [PATCH bpf-next v3 15/15] bpf/selftests: add tcp/udp iterator programs to selftests
Date: Mon, 22 Jun 2020 17:36:43 -0700 [thread overview]
Message-ID: <20200623003643.3075182-1-yhs@fb.com> (raw)
In-Reply-To: <20200623003626.3072825-1-yhs@fb.com>
Added tcp{4,6} and udp{4,6} bpf programs into test_progs
selftest so that they at least can load successfully.
$ ./test_progs -n 3
...
#3/7 tcp4:OK
#3/8 tcp6:OK
#3/9 udp4:OK
#3/10 udp6:OK
...
#3 bpf_iter:OK
Summary: 1/16 PASSED, 0 SKIPPED, 0 FAILED
