*ss* now supports SCTP sockets list
Previously, the *netstat* utility provided a list of Stream Control Transmission Protocol (SCTP) sockets. With this update, the *ss* utility is able to display the same list.

Description

`ss' currently doesn't support SCTP at all. Marking as FutureFeature. There's a usable procfs interface. Requesting devel ack. Discussion regarding sctp_diag kernel interface has started already, so it should be possible to accomplish this for RHEL7.3. Patch series implementing sctp_diag support in 'ss' has been sent upstream: http://marc.info/?l=linux-netdev&m=146983127501267&w=2 Please note though that it requires a few kernel changes for full functionality, tracked in Bug 1361728. Sadly, upstream has not accepted the submitted patch yet, which is why this ticket was left untouched for so long. On the other hand, it is not a good idea to import a large change like this one at this point, especially since it didn't see any upstream testing at all yet. Finally, upstream accepted my patches:

Author: Phil Sutter <phil>

ss: Add support for SCTP protocol
This makes use of the sctp_diag interface recently added to the kernel.
Joint work with Xin Long who provided the PoC implementation which I
merely polished up a bit.

Hi Phil, I found one, simple, documentation issue. There is no mention about sctp in -A option in ss man-page and ss help, where all socket types are listed. I think, it should be there. Would be possible to fix it? Hi Jaroslav, (In reply to Jaroslav Aster from comment #27) > I found one, simple, documentation issue.

I've quickly prepared a patch for upstream and submitted it: http://marc.info/?l=linux-netdev&m=148907572801154&w=2 Thanks, Phil Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2017:2171 Arrived here because of bug 1544898 ("ss indiscriminately loads sctp kernel modules") - does anyone know why the latter is locked? |
