[LTP] [RFC] SCTP tests in LTP vs. on github.com/sctp

[Petr Vorel]

Hi all,

SCTP tests lksctp-tools [1] are also in LTP [2].
IMHO it's not worth to have it on both places.

lksctp-tools looks like to be the official ones [3] so maybe drop it from LTP?

Version in LTP was updated to 1.0.15 some time ago (upstream has 1.0.19, containing various fixes [4],
maybe worth to be backported to lksctp-tools? Frankly speaking even being older
version the LTP code looks to me better. One test was even rewritten to LTP new
C API [5] in order to apply more improvements [6].

BTW I'd really recommend lksctp-tools project to take new LTP C API [7] and
rewrite tests into it. But are these tests still relevant? (is it worth of
work?)

Kind regards,
Petr

FYI we've been thinking about back in 2013.
https://lore.kernel.org/ltp/20130805121135.GB8739@rei/

I'd personally prefer sctp folks maintain them and we removed them from LTP.

Kind regards,
Petr

Agree. I wasn't aware of the copy in LTP, btw.

A question I have now is, is getting more exposure because it is in
LTP? As in, does it get executed periodically by bots somewhere?

These are nice tips, thanks. We certainly can have a take on them.

Best regards,
Marcelo

Maybe yes, hard to tell. Not sure even how many people even run SCTP tests
included by LTP. We could ask at automated-testing [8] (embedded people + hopefully
folks from KernelCI [9]) or send the update there. We'd also put a link in
to remaining location in git commit message if agree to remove it from LTP.

Yw.

Generally I think that not many run the LTP network tests, but it seems
that the intel 0-day has at least a job definition for the LTP sctp
tests:

https://github.com/intel/lkp-tests/blob/3fece75132266f680047f4e1740b39c5b3faabbf/jobs/ltp-stress.yaml

Not sure how often of if they even run it though.
