[PATCH v1 net-next 1/2] selftest: af_unix: Create its own .gitignore.

[Kuniyuki Iwashima]

Somehow AF_UNIX tests have reused ../.gitignore,
but now NIPA warns about it.

Let's create .gitignore under af_unix/.

[PATCH v1 net-next 2/2] selftest: af_unix: Extend recv() timeout in so_peek_off.c.

[Kuniyuki Iwashima]

so_peek_off.c is reported to be flaky on NIPA:

  # # so_peek_off.c:149:two_chunks_overlap_blocking:Expected -1 (-1) != bytes (-1)
  # # two_chunks_overlap_blocking: Test terminated by assertion
  # #          FAIL  so_peek_off.stream.two_chunks_overlap_blocking

The test fork()s a child process to send() data after 1ms to
wake up the parent process being blocked (up to 3ms) on recv().

But, from the log, the parent woke up after 3ms timeout, so it
could be too short when the host is overloaded.

Let's extend it to 5s.

Thanks for following up!

NIPA says it doesn't apply:

error: patch failed: tools/testing/selftests/net/.gitignore:35
error: tools/testing/selftests/net/.gitignore: patch does not apply
hint: Use 'git am --show-current-patch=diff' to see the failed patch
hint: When you have resolved this problem, run "git am --continue".
hint: If you prefer to skip this patch, run "git am --skip" instead.
hint: To restore the original branch and stop patching, run "git am --abort".
hint: Disable this message with "git config set advice.mergeConflict false"

Does it have a dependency in net or on the list?

Oh sorry, I forgot I had some downstream tests.
Will rebase on clean net-next.

Feel free to skip the 24h wait. I'd like to get the netdev foundation CI
to a clean state so I can shut off the AWS one completely.
