description |
When upgrading from version 1.9-3ubuntu10.1, a previously working machine can't successfully reboot completely.
ifup is hanging indefinitely, with this process structure (from "pstree -a 1299"):
ifup,1299 -a
└─run-parts,1501 /etc/network/if-pre-up.d
└─bridge,1502 /etc/network/if-pre-up.d/bridge
└─bridge,1508 /etc/network/if-pre-up.d/bridge
└─vlan,1511 /etc/network/if-pre-up.d/vlan
└─ifup,1532 eth0
<begin content of /etc/network/interfaces>
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.10.65
netmask 255.255.255.192
gateway 192.168.10.66
auto eth0.11
address 192.168.11.1
netmask 255.255.255.0
auto br1134
iface br1134 inet manual
bridge_ports eth0.1134
bridge_stp off
bridge_fd 0
<end content of /etc/network/interfaces>
The underlying interface eth0.1134 is not explicitly defined, but was previously auto-created during "ifup -a" execution. This apparently fails now.
Reverting back to the 10.1 version re-establishes old behavior. |
[impact]
in bug 1573272, the vlan pkg was changed to perform a full ifup inside its if-pre-up.d/vlan script. This allowed correct ordering of ifup for a vlan and its raw-device, as previously there was a race condition between them (see that bug for details).
However, this causes hangs during ifup with certain specific configs. The reasons are given starting in comment 13.
The result is a regression for those using the specific ifupdown configs; when they try to reboot and/or ifup -a, it will hang trying to bring up their network, preventing boot from finishing (or hanging before the network is fully configured).
[test case]
upgrade to the latest vlan package and configure the system with an affected ifupdown config, then reboot. The reboot will hang while trying to bring the network up.
see the original description below for an example ifupdown config to reproduce this, although there are other possible configs that will/may trigger this regression.
[regression potential]
The fix for this moves the creation of the vlan(s) corresponding to a physical raw-device 'hotplug' event out of the udev processing path for the raw-device, and into an ifup post script for the raw-device ifup. If this is not done correctly, then any interfaces that are hotplugged, and have vlans configured on them, may fail to correctly create/configure their vlan(s).
This change does remove the direct call to ifup from the if-pre-up.d (or if-up.d) scripts, so there should not be any regression potential for more ifup deadlocks.
[other info]
this required both ifupdown and vlan to be patched. vlan was patched to remove the problematic call to ifup from the vlan pre-up script, and add a call to create the vlan interface(s) from a new post-up script, as well as adding a parameter to vlan-network-interface script to handle the call from udev itself differently than a call from elsewhere (such as the if-up.d/vlan script). this works for bootup and ifup/ifup -a, but fails for device hotplug because of a bug in ifupdown that prevents calling ifquery from an ifup script; that has been patched upstream already, and is the only ifupdown change needed here.
