[Bug 1514009] [NEW] Ubuntu 12.04 if-pre-up script has sometimes infinite loop

[Carlisle]

Public bug reported:

Hi,


My release:

Description:	Ubuntu 12.04.5 LTS
Release:	12.04


Version:

  Installed: 1.1.0-19ubuntu5


Description:

In the if-pre-up script provided by this package there is a while true
loop:


[ ! -f /run/network/ifenslave.$BOND_MASTER ] && echo "Waiting for bond master $BOND_MASTER to be ready"
	while :; do
		if [ -f /run/network/ifenslave.$BOND_MASTER ]; then
			break
		fi
		sleep 0.1
	done


If the file in question is never created this loop will not exit, and neither will ifup until it is sent to the background and killed (control + c does not break). Maybe there is something wrong happening on my system that never should, but I also feel there shouldn't be the potential for an infinite loop while bringing up network interface. There should either be a timeout or logic to determine why the file is not there.


Thanks,

Carlisle
