You have been subscribed to a public bug by Igor I Shatunov (raider444): In iptables 1.8.9, a regression was introduced that changes the behavior of the -n flag.
Previously, supplying -n would *not* display numerical values for the "prot" column of the -L output: # iptables --version iptables v1.8.7 (nf_tables) # iptables -nL Chain LIBVIRT_OUT (1 references) target prot opt source destination ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:53 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 However, with the faulty patch, this changed to numerical values: # iptables --version iptables v1.8.9 (legacy) # iptables -nL Chain LIBVIRT_OUT (1 references) target prot opt source destination ACCEPT 17 -- 0.0.0.0/0 0.0.0.0/0 udp dpt:53 ACCEPT 6 -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 This breaks parsing in the resource-agents package, namely the portblock resource agent. Parsing has since been relaxed in resource-agents: https://github.com/ClusterLabs/resource-agents/pull/1924 (released in resource-agents v4.14.0). There is an upstream bug report: https://bugzilla.netfilter.org/show_bug.cgi?id=1729 For reference, there is also a report with the Debian project: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1067733 The offending commit was reverted upstream: https://git.netfilter.org/iptables/commit/?id=34f085b1607364f4eaded1140060dcaf965a2649 But the revert has not been released yet. Ubuntu Noble ships version 1.8.10 of iptables, which is still affected. The solution would be to apply the reverted patch mentioned above. ** Affects: iptables Importance: Unknown Status: Fix Released ** Affects: iptables (Ubuntu) Importance: Undecided Status: Confirmed -- iptables: regression in 1.8.9 with -n breaks portblock in resource-agents https://bugs.launchpad.net/bugs/2067274 You received this bug notification because you are a member of Ubuntu Apps bug tracking, which is subscribed to the bug report. -- Mailing list: https://launchpad.net/~ubuntu-apps-bugs Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-apps-bugs More help : https://help.launchpad.net/ListHelp
