2020-07-29bpf, selftests: use :: 1 for localhost in tcp_server.pyJohn Fastabend1-1/+1
Using localhost requires the host to have a /etc/hosts file with that specific line in it. By default my dev box did not, they used ip6-localhost, so the test was failing. To fix remove the need for any /etc/hosts and use ::1. I could just add the line, but this seems easier.

2019-02-04selftests/bpf: use localhost in tcp_{server,client}.pyStanislav Fomichev1-4/+1
Bind and connect to localhost. There is no reason for this test to use non-localhost interface. This lets us run this test in a network namespace. Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
2018-07-25bpf: Add Python 3 support to selftests scripts for bpfJeremy Cline1-8/+8
Adjust tcp_client.py and tcp_server.py to work with Python 3 by using the print function, marking string literals as bytes, and using the newer exception syntax. This should be functionally equivalent and supports Python 3+. Signed-off-by: Jeremy Cline <jcline@redhat.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
2018-01-26bpf: add selftest for tcpbpfLawrence Brakmo1-0/+83
Added a selftest for tcpbpf (sock_ops) that checks that the appropriate callbacks occured and that it can access tcp_sock fields and that their values are correct. Run with command: ./test_tcpbpf_user Adding the flag "-d" will show why it did not pass.
