https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=286179 Bug ID: 286179 Summary: Passing a vlan interface to a vnet jail result in a stuck dying state Product: Base System Version: 14.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: florian.millet@laposte.net Created attachment 259669 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=259669&action=edit The config file fot the stuck jail Hello everyone, I stumbled upon a problem when working on jail networking with pseudo interfaces like vlan. If you give a vlan interface to a vnet jail, everything works fine until you try to stop the jail. It gets stuck in a dying state (appearing in jls -d). It seems to be very similar to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264981 which is closed FIXED. Like the other bug if I try to ifconfig destroy it says that the vlan interface does not exist, if I try to create it it says that it already exists. This happened on a FreeBSD 14.2-RELEASE-p3 (releng/14.2-n269524-1eb03b059e56) kernel with custom options, the vlan is created on a lacp lagg device, itself created upon 2 Mellanox mlx5 interface (MT27800 / ConnectX-5). Appjail was used to create thin vnet jails but I don't think it has any impact on this problem. Steps to reproduce : - Create a vlan interface on a lagg vlandev : ifconfig vlan1000 create vlan 1000 vlandev lagg1 - give the created vlan to a vnet jail (vnet.interface += "vlan1000"; in jail.conf) - start the jail - everything is working as intended - stop the jail After the stop : server1352# ifconfig vlan1000 ifconfig: interface vlan1000 does not exist server1352# ifconfig vlan1000 create vlan 1000 vlandev lagg1 ifconfig: interface vlan1000 already exists server1352# ifconfig vlan1000 destroy ifconfig: interface vlan1000 does not exist server1352# jls -d JID IP Address Hostname Path 2 br1000.jail.storage.ovh.net /appjail/jails/br1000/jail server1352# Bug #264981 references a problem with inpcb that should have been fixed in commit 5fd1a67e885e and while it seems to have fixed the original problem with a lo pseudo interface, the problem persist with other type of pseudo interface like vlan. -- You are receiving this mail because: You are the assignee for the bug.home | help
