I confirm patch:
https://github.com/shemminger/iproute2/commit/38d209ecf2ae966b9b25de4acb60cdffb0e06ced
Fixes the issue.
Without the patch:
(c)inaddy@ctdb:~/work/sources/ubuntu/iproute2/misc$ sudo ss -tn state
established "( src [172.16.17.2] || src [172.16.17.3] )" "( sport == :2049 )"
ss: bison bellows (while parsing filter): "syntax error!" Sorry.
Usage: ss [ OPTIONS ]
ss [ OPTIONS ] [ FILTER ]
Patch applied:
(c)inaddy@ctdb:~/work/sources/ubuntu/iproute2/misc$ sudo ./ss -tn state
established "( src [172.16.17.2] || src [172.16.17.3] )" "( sport == :2049 )"

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