Hello Rafael, or anyone else affected, Accepted iproute2 into disco-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/iproute2/4.18.0-1ubuntu2.1 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-disco to verification-done-disco. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-disco. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: iproute2 (Ubuntu Disco) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-disco -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to iproute2 in Ubuntu.

[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. [Other Info] 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: ---- # Debian Sid inaddy@workstation:~$ ss -tn state established "( src [172.16.17.2] || src [172.16.17.3] )" "( sport == :2049 )" Recv-Q Send-Q Local Address:Port Peer Address:Port # Ubuntu Ubuntu 16.04 LTS (Xenial Xerus) (c)inaddy@xenial:~$ ss -tn state established "( src [172.16.17.2] || src [172.16.17.3] )" "( sport == :2049 )" Recv-Q Send-Q Local Address:Port Peer Address:Port # Ubuntu 18.04 LTS (Bionic Beaver) (c)inaddy@bionic:~$ ss -tn state established "( src [172.16.17.2] || src [172.16.17.3] )" "( sport == :2049 )" Recv-Q Send-Q Local Address:Port Peer Address:Port # Ubuntu 18.10 (Cosmic Cuttlefish) (c)inaddy@cosmic:~$ 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 ] ---- 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).
