selftests/txtimestamp: Fix an equals vs assign bug

2019-01-15T21:33:44Z

This should be == instead of =. Fixes: b52354aa068e ("selftests: expand txtimestamp with ipv6 dgram + raw and pf_packet") Signed-off-by: Dan Carpenter Acked-by: Willem de Bruijn Signed-off-by: David S. Miller

selftests: add txtimestamp kselftest

2018-12-21T01:01:17Z

Run the transmit timestamp tests as part of kselftests. Add a txtimestamp.sh test script that runs most variants: ipv4/ipv6, tcp/udp/raw/raw_ipproto/pf_packet, data/nodata, setsockopt/cmsg. The script runs tests with netem delays. Refine txtimestamp.c to validate results. Take expected netem delays as input and compare against real timestamps. To run without dependencies, add a listener socket to be able to connect in the case of TCP. Add the timestamping directory to the kselftests Makefile. Build all the binaries. Only run verified txtimestamp.sh. Signed-off-by: Willem de Bruijn Acked-by: Soheil Hassas Yeganeh Signed-off-by: David S. Miller

selftests: expand txtimestamp with ipv6 dgram + raw and pf_packet

2018-12-21T01:01:17Z

Expand the transmit timestamp regression test with support for missing protocols: ipv6 datagram and raw and pf_packet. Also refine resolve_hostname to independently request AF_INET or AF_INET6 addresses. Else, ipv4 addresses may be returned as AF_INET6.

selftests: expand txtimestamp with cmsg support

2018-12-21T01:01:16Z

Commit 3dd17e63f513 ("sock: accept SO_TIMESTAMPING flags in socket cmsg") added support for passing tx timestamping options per-call in sendmsg. Expand the txtimestamp test with support for this feature. Signed-off-by: Willem de Bruijn Acked-by: Soheil Hassas Yeganeh Signed-off-by: David S. Miller

selftests/txtimestamp: Add more configurable parameters

2018-03-16T19:05:57Z

Add a way to configure if poll() should wait forever for an event, the number of packets that should be sent for each and if there should be any delay between packets. Signed-off-by: Vinicius Costa Gomes Signed-off-by: David S. Miller

selftests: Move networking/timestamping from Documentation

2016-09-20T15:59:50Z

Remove networking from Documentation Makefile to move the test to selftests. Update networking/timestamping Makefile to work under selftests. These tests will not be run as part of selftests suite and will not be included in install targets. They can be built and run separately for now. This is part of the effort to move runnable code from Documentation. Acked-by: Jonathan Corbet Signed-off-by: Shuah Khan
