Investigating an issue for CTDB (LP: #722201), after suggesting a fix on ss syntax to CTDB upstream project, we discovered that "ss" seems to be broken in Ubuntu since Ubuntu Cosmic:

I have generated a pkg using upstream iproute2 source code and it does not suffer the issue.

[Impact]
* ss can't filter using single entries in parentheses
[Test Case]
* ss -tn state established "( src [172.16.17.2] || src [172.16.17.3] )" "( sport == :2049 )"

[Regression Potential]
* ss interpreter (bison powered) could be broken
* patch is based in an upstream fix and was tested
* would likely not jeopardize ip command (higher issues)

I have generated a package using Ubuntu cosmic source package, without debian/patches/*, and verified the issue still persists (not being introduced by any of our packages, and being present if vanilla upstream version used in Cosmic). |
[Impact]
* ss won't be able to run commands with single filters inside parentheses, like: "( sport == :X )", for example.
* A workaround is to remove "( )" from single filters, since it looks the issue does not affect 2 filters being put together in the same parentheses, like: " ( X and Y ) and Y " instead of ( X and Y ) and ( Y )".
* CTDB is unable to use ss filter to obtain nodes public IP addresses in order to fail over services (LP: #722201).
[Test Case]
* Having an Ubuntu Cosmic, Disco or Eoan, try to execute the following command:
$ ss -tn state established "( src [172.16.17.2] || src [172.16.17.3] )" "( sport == :2049 )"
Independent of the IPs or ports being used. Copying and pasting the command should be enough for you to know if you are affected.
Bad Result:
ss: bison bellows (while parsing filter): "syntax error!" Sorry.
Usage: ss [ OPTIONS ]
ss [ OPTIONS ] [ FILTER ]
-h, --help this message
...
Expected Result:
Recv-Q Send-Q Local Address:Port Peer Address:Port
...
* test case was discovered during CTDB scripts execution
[Regression Potential]
* biggest risk would be to affect ss interpreter (worst case scenario).
* the proposed patch is based in upstream fix and was tested against the same issue reported as the reproducer (above) and some other generic ss commands.
* any problem here is unlikely to change iproute2 most important command interpreter, "ip", since the patch is applied against ss code.
