selftests: move timestamping selftests to net folder

2020-03-30T04:48:30Z

For historical reasons, there are several timestamping selftest targets in selftests/networking/timestamping. Move them to the standard directory for networking tests: selftests/net. Signed-off-by: Jian Yang Acked-by: Willem de Bruijn Acked-by: Jakub Kicinski Signed-off-by: David S. Miller

selftests: txtimestamp: print statistics for timestamp events.

2020-03-22T03:14:13Z

Statistics on timestamps is useful to quantify average and tail latency. Print timestamp statistics in count/avg/min/max format. Signed-off-by: Jian Yang Acked-by: Willem de Bruijn Acked-by: Soheil Hassas Yeganeh Signed-off-by: David S. Miller

selftests: txtimestamp: add support for epoll().

2020-03-22T03:14:13Z

Add the following new flags: -e: use level-triggered epoll() instead of poll(). -E: use event-triggered epoll() instead of poll(). Signed-off-by: Jian Yang Acked-by: Willem de Bruijn Acked-by: Soheil Hassas Yeganeh Signed-off-by: David S. Miller

selftests: txtimestamp: add new command-line flags.

2020-03-22T03:14:13Z

A longer sleep duration between sendmsg()s makes more cachelines to be evicted and results in higher latency. Making the duration configurable. Add the following new flags: -S: Configurable sleep duration. -b: Busy loop instead of poll(). Remove the following flag: -D: No delay between packets: subsumed by -S.

selftests: txtimestamp: allow printing latencies in nsec.

2020-03-22T03:14:12Z

Txtimestamp reports latencies in uses resolution, while nsec is needed in cases such as measuring latencies on localhost. Add the following new flag: -N: print timestamps and durations in nsec (instead of usec) Signed-off-by: Jian Yang Acked-by: Willem de Bruijn Acked-by: Soheil Hassas Yeganeh Signed-off-by: David S. Miller

selftests: txtimestamp: allow individual txtimestamp tests.

2020-03-22T03:14:12Z

The wrapper script txtimestamp.sh executes a pre-defined list of testcases sequentially without configuration options available. Add an option (-r/--run) to setup the test namespace and pass remaining arguments to txtimestamp binary. The script still runs all tests when no argument is passed.

selftests: timestamping: Fix SIOCGSTAMP undeclared build failure

2019-06-28T20:31:12Z

Add missing linux/sockios.h include to fix the following SIOCGSTAMP undeclared build error. In addition, remove the local defines for SIOCGSTAMPNS and SIOCSHWTSTAMP and pick them up from linux/sockios.h. timestamping.c:249:19: error: SIOCGSTAMP undeclared if (ioctl(sock, SIOCGSTAMP, &tv)) Signed-off-by: Shuah Khan

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S. Miller

selftests: fix timestamping Makefile

2019-02-14T17:03:16Z

The clean target in the makefile conflicts with the generic kselftests lib.mk, and fails to properly remove the compiled test programs. Remove the redundant rule, the TEST_GEN_FILES will be already removed by the CLEAN macro in lib.mk. Signed-off-by: Deepa Dinamani Acked-by: Shuah Khan Signed-off-by: David S. Miller
