bpf: test_sockmap, add options for msg_pop_data() helper

2018-11-28T21:07:57Z

Similar to msg_pull_data and msg_push_data add a set of options to have msg_pop_data() exercised. Signed-off-by: John Fastabend Signed-off-by: Daniel Borkmann

bpf: test_sockmap add options to use msg_push_data

2018-10-20T19:37:12Z

Add options to run msg_push_data, this patch creates two more flags in test_sockmap that can be used to specify the offset and length of bytes to be added. The new options are --txmsg_start_push to specify where bytes should be inserted and --txmsg_end_push to specify how many bytes. This is analagous to the options that are used to pull data, --txmsg_start and --txmsg_end. In addition to adding the options tests are added to the test suit to run the tests similar to what was done for msg_pull_data. Signed-off-by: John Fastabend Signed-off-by: Daniel Borkmann

bpf: sockmap, add msg_peek tests to test_sockmap

2018-10-17T00:30:32Z

Add tests that do a MSG_PEEK recv followed by a regular receive to test flag support. Signed-off-by: John Fastabend Signed-off-by: Daniel Borkmann

bpf, tls: add tls header to tools infrastructure

2018-10-16T15:10:01Z

Andrey reported a build error for the BPF kselftest suite when compiled on a machine which does not have tls related header bits installed natively: test_sockmap.c:120:23: fatal error: linux/tls.h: No such file or directory #include ^ compilation terminated. Fix it by adding the header to the tools include infrastructure and add definitions such as SOL_TLS that could potentially be missing.

bpf: add tls support for testing in test_sockmap

2018-10-15T19:23:19Z

This adds a --ktls option to test_sockmap in order to enable the combination of ktls and sockmap to run, which makes for another batch of 648 test cases for both in combination. Signed-off-by: John Fastabend Signed-off-by: Daniel Borkmann Signed-off-by: Alexei Starovoitov

bpf: use --cgroup in test_suite if supplied

2018-08-29T15:29:55Z

If the user supplies a --cgroup value in the arguments when running the test_suite go ahaead and run the self tests there. I use this to test with multiple cgroup users. Signed-off-by: John Fastabend Signed-off-by: Daniel Borkmann

bpf: sockmap test remove shutdown() calls

2018-08-29T15:29:54Z

Currently, we do a shutdown(sk, SHUT_RDWR) on both peer sockets and a shutdown on the sender as well. However, this is incorrect and can occasionally cause issues if you happen to have bad timing. First peer1 or peer2 may still be in use depending on the test and timing. Second we really should only be closing the read side and/or write side depending on if the test is receiving or sending. But, really none of this is needed just remove the shutdown calls. Signed-off-by: John Fastabend Signed-off-by: Daniel Borkmann

bpf, sockmap: fix cork timeout for select due to epipe

2018-08-08T19:06:17Z

I ran into the same issue as a009f1f396d0 ("selftests/bpf: test_sockmap, timing improvements") where I had a broken pipe error on the socket due to remote end timing out on select and then shutting down it's sockets while the other side was still sending. We may need to do a bigger rework in general on the test_sockmap.c, but for now increase it to a more suitable timeout.

tools/bpf: fix test_sockmap failure

2018-06-21T22:31:42Z

On one of our production test machine, when running bpf selftest test_sockmap, I got the following error: # sudo ./test_sockmap libbpf: failed to create map (name: 'sock_map'): Operation not permitted libbpf: failed to load object 'test_sockmap_kern.o' libbpf: Can't get the 0th fd from program sk_skb1: only -1 instances ...... load_bpf_file: (-1) Operation not permitted ERROR: (-1) load bpf failed The error is due to not-big-enough rlimit struct rlimit r = {10 * 1024 * 1024, RLIM_INFINITY}; The test already includes "bpf_rlimit.h", which sets current and max rlimit to RLIM_INFINITY. Let us just use it. Signed-off-by: Yonghong Song Signed-off-by: Daniel Borkmann
