Per association statistics

Per association statistics

[Kiss, Zoltan (NSN - HU/Budapest)]

Hi,

I've recently tried an application on 2.6.34.6, and I had to realize,
that SCTP_GET_ASSOC_STATS getsockopt works no longer anymore, like in
2.6.21. I couldn't find any source why it was removed from stack, and is
there anything to replace it. I've especially need in/out byte/packet
counters, but as I see I can find it on a per process basis, but I need
these counters for one specific association/socket. I've only found the
old retrans counter, but it also cumbersome as it is available only
through /proc filesystem.
Why was this feature removed, and how can I workaround its lack?

Regards,

Zoltan Kiss

Not sure.  I remember it being added.  I'll have to check the history
to see what happened.

If I am right, nobody has added the SCTP_GET_ASSOC_STATS option for linux,
and no spec has defined this option. It seems that just solaris using this option.
LKSCTP does not support count the in/out bytes by asoc. I think your application
should know the in/out bytes, why you need to get them from kernel?
