Hello, One of our tests failed due to iptables. It works fine with kernels <= 4.11 and 4.12-rc* (from rawhide). The problem is that the command for deleting a rule returns an error. [root@zdtm ~]# unshare -n [root@zdtm ~]# iptables -w -t filter --protocol tcp -A INPUT --dport 9999 -j DROP [root@zdtm ~]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination DROP tcp -- anywhere anywhere tcp dpt:distinct Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination [root@zdtm ~]# iptables -w -t filter --protocol tcp -D INPUT --dport 9999 -j DROP iptables: Bad rule (does a matching rule exist in that chain?). [root@zdtm ~]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination DROP tcp -- anywhere anywhere tcp dpt:distinct Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination [root@zdtm ~]# uname -a Linux zdtm.openvz.org 4.11.5-200.fc25.x86_64 #1 SMP Wed Jun 14 17:17:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux https://bugzilla.redhat.com/show_bug.cgi?id=1459676 Thanks, Andrei _______________________________________________ kernel mailing list -- kernel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kernel-leave@xxxxxxxxxxxxxxxxxxxxxxx
