description |
we're trying to migrate our network configuration from lucid to precise. in 10.04 we tied eth0+eth1 together into bond0, then set br0 up on top of that and assigned an address via dhcp. in 12.04 this only works if br0 is configured with a static ip address. it fails when trying to use dhcp. to simplify testing i've removed eth1 from the configuration (sanity checked against http://www.stgraber.org/2012/01/04/networking-in-ubuntu-12-04-lts/ ):
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
bond-master bond0
auto bond0
iface bond0 inet manual
bond-slaves none
bond-mode 802.3ad
bond-miimon 100
auto br0
iface br0 inet dhcp
bridge_ports bond0
bridge_stp off
the above results in a system w/o network connectivity. the dhcp server reports requests from an unexpected mac addr (different each boot). udevd logs "timeout 'bridge-network-interface'". poking around a little before the timeout shows the following 2 groups of processes:
|-ifup,1361 --allow auto eth0
| `-sh,1363 -c run-parts /etc/network/if-pre-up.d
| `-run-parts,1364 /etc/network/if-pre-up.d
| `-ifenslave,1392 /etc/network/if-pre-up.d/ifenslave
| `-sleep,2380 0.1
| |-udevd,599 --daemon
| | `-bridge-network-,1429 /lib/udev/bridge-network-interface
| | `-ifup,1457 --allow auto br0
| | `-sh,1540 -c dhclient3 -e IF_METRIC=100 -pf /var/run/dhclient.br0.pid -lf /var/lib/dhcp/dhclient.br0.leases -1 br0
| | `-dhclient3,1541 -e IF_METRIC=100 -pf /var/run/dhclient.br0.pid -lf /var/lib/dhcp/dhclient.br0.leases -1 br0
the ifenslave appears to be looping over that `sleep` (testing for /run/network/ifenslave.bond0) until it is killed and the dhclient is making its request w/the unexpected mac addr (also reported in `ip link show br0`). interestingly br0's mac addr matches that of eth0 (as expected) once bridge-network-interface has timed out and been killed.
a workaround appears to be adding the line:
pre-up /sbin/ifup --allow auto bond0
to the "auto br0" stanza.

[rationale]
With some specific configuration, the boot hangs for minutes in udev as ifupdown is waiting for an interface to show up.
[test case]
- Use one of the configurations listed in this bug or its duplicate, boot the machine with it and observe it hanging for a couple of minutes.
- Apply the update
- Check that the machine now works much faster and that the interface is properly configured.
[regression potential]
I can't see of a situation where someone would be depending on the broken behaviour which wouldn't in itself be a bug. The change landed fairly early in Ubuntu 12.10 and no regression has been reported so far. Worst case scenario, it's easy to revert.
