I have downgraded iproute2 package (using -updates pocket) and it also
gave the same errors:
(c)inaddy@iproute2verification:~/work/sources/ubuntu/chrony/test/simulation$
./111-knownclient
Testing reply to client configured as server:
network with 1*1 servers and 1 clients:
...
checking port numbers in packet log:
node 1: BAD
node 2: BAD
FAIL
(c)inaddy@iproute2verification:~/work/sources/ubuntu/chrony/test/simulation$
./112-port
Testing port and acquisitionport directives:
network with 1*1 servers and 1 clients:
...
checking port numbers in packet log:
node 1: BAD
node 2: BAD
FAIL
So its not because of this SRU.

Title:
ss seems broken when using multiple filters in the same cmdline
Status in iproute2 package in Ubuntu:
Fix Released
Status in iproute2 source package in Cosmic:
Won't Fix
Status in iproute2 source package in Disco:
Fix Committed
Status in iproute2 source package in Eoan:
Fix Released
Bug description:
[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.

ORIGINAL DESCRIPTION:
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. 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).
