Commit 852c8cbf34d3 (selftests/kselftest/runner.sh: Add 45 second
timeout per test) adds support for a new per-test-directory "settings"
file. But this only works for tests not in a sub-subdirectories, e.g.
- tools/testing/selftests/rtc (rtc) is OK,
- tools/testing/selftests/net/mptcp (net/mptcp) is not.
We have to increase the timeout for net/mptcp tests which are not
upstreamed yet but this fix is valid for other tests if they need to add
a "settings" file, see the full list with:
tools/testing/selftests/*/*/**/Makefile
Note that this patch changes the text header message printed at the end
of the execution but this text is modified only for the tests that are
in sub-subdirectories, e.g.
ok 1 selftests: net/mptcp: mptcp_connect.sh
Before we had:
ok 1 selftests: mptcp: mptcp_connect.sh
But showing the full target name is probably better, just in case a
subsubdir has the same name as another one in another subdirectory.

Hi Shuah,
First, thank you for maintaining the Kernel Selftest framework!

Sorry to bother you again with this but by chance, did you have a look
at the patch below? :)
It doesn't only fix an issue with MPTCP, not in the kernel yet. But it
also fixes the issue of taking the right "settings" file (if available)
for any other tests in a sub-directory, e.g.:
drivers/dma-buf
filesystems/binderfs
net/forwarding
networking/timestamping
But I guess all tests in powerpc/* dirs and others.
Cheers,
Matt

Thanks for the ping! I missed this patch when you originally sent it.
Yes, this make sense to me:

As an improvement on this, I wonder if we need to walk all directories
between $BASEDIR and $DIR? Actually, let me write this and send it...

Kees, Thank you for this review!
Shuah, I am sorry to send you this new request. It is just to inform you
that the first selftests for MPTCP are now in "net-next" repo, ready for
the future Linux 5.6.
We would then be very happy to see this patch here below for the
kselftest framework accepted to avoid timeouts. Locally we apply this
patch before running the selftests but we cannot ask everybody running
MPTCP' selftests to do the same :)

I am sorry for the delay. My bad. Looks like I just missed it. I will
make sure it gets into 5.6-rc1
Thanks for your patience and ping.

That's alright, thank you for having applied this patch in your "next"
