$ sudo ifquery --list --allow auto; echo $?;
ifquery: failed to lock lockfile /run/network/.ifstate.lock: Bad file descriptor

This seems possibly quite serious as /etc/network/if-up.d/upstart uses this program to determine the "auto" interfaces and then emits static-network-up.

This seems possibly quite serious as /etc/network/if-up.d/upstart uses this program to determine the "auto" interfaces and then emits static-network-up.
Also interesting, possibly related and possibly a bug in and of itself:
$ cp /etc/network/interfaces /tmp/interfaces
$ sudo ifquery --interfaces /tmp/interfaces --list --allow=auto
ifquery: failed to lock lockfile /run/network/.ifstate.lock: Bad file descriptor
Seems odd that it would do anything with /run/network/.ifstate.lock in this case since, by doing so, it means i'd have to have privilege to read that file in order to have it parse my provided --interfaces= file.

== Begin SRU ==
[Impact]
This bug is a regression of the fix applied under bug 1160490.
The bug is that 'ifquery --list' will try to obtain a lock on a file in /run, which will fail with an error message of 'Bad file descriptor'.
The changes applied here are a backport of upstream fix fb3055c2c4f0 [1].
[1]
[Test Case]
Ideally both the test case from bug 1160490 [2] and the following test case should be done.
$ sudo ifquery --list --allow auto
lo
eth0
$ ifquery --list --allow auto
lo
eth0
Success is a list of the 'auto' interfaces that in /etc/network/interfaces. (in a cloud image, thats eth0 and lo). This should work both as root and non-root. Failure would show 'failed to lock lockfile' or non-zero exit value.
Additionally, verify that you can query something other than the default interfaces file as root and non-root.
$ ( echo "auto eth1"; echo "iface eth1 inet dhcp"; ) > /tmp/my.interfaces
$ sudo ifquery --list --allow auto --interfaces=/tmp/my.interfaces
lo
eth1
$ ifquery --list --allow auto --interfaces=/tmp/my.interfaces
lo
eth1
the 'lo' output is expected as 'lo' is automatically auto. Failure here would be the same 'failed to lock lockfile' or non-zero exit.
It also surely wouldn't hurt to do:
$ sudo ifdown eth0; sudo ifup eth0
Just to make sure that functions.
[Regression Potential]
* (from bug 1160490) This fix backports a change from upstream ifupdown. Instead of locking a statefile it locks a lockfile.
* the change here is very trivial. It chooses to not fail on failure to get lockfile if the operation is 'no_act' (see [1]).

Additionally, verify that you can query something other than the default interfaces file as root and non-root.
$ ( echo "auto eth1"; echo "iface eth1 inet dhcp"; ) > /tmp/my.interfaces
$ sudo ifquery --list --allow auto --interfaces=/tmp/my.interfaces
lo
eth1
$ ifquery --list --allow auto --interfaces=/tmp/my.interfaces
lo
eth1
the 'lo' output is expected as 'lo' is automatically auto. Failure here would be the same 'failed to lock lockfile' or non-zero exit.
It also surely wouldn't hurt to do:
$ sudo ifdown eth0; sudo ifup eth0
Just to make sure that functions.
[Regression Potential]
* (from bug 1160490) This fix backports a change from upstream ifupdown. Instead of locking a statefile it locks a lockfile.
* the change here is very trivial. It chooses to not fail on failure to get lockfile if the operation is 'no_act' (see [1]).

$ sudo ifquery --list --allow auto; echo $?;
ifquery: failed to lock lockfile /run/network/.ifstate.lock: Bad file descriptor

This seems possibly quite serious as /etc/network/if-up.d/upstart uses this program to determine the "auto" interfaces and then emits static-network-up.
This reproduces on a fresh saucy image with serial=20130916.
Also interesting, possibly related and possibly a bug in and of itself:
$ cp /etc/network/interfaces /tmp/interfaces
$ sudo ifquery --interfaces /tmp/interfaces --list --allow=auto
ifquery: failed to lock lockfile /run/network/.ifstate.lock: Bad file descriptor
Seems odd that it would do anything with /run/network/.ifstate.lock in this case since, by doing so, it means i'd have to have privilege to read that file in order to have it parse my provided --interfaces= file.
For reference, on raring instance as non-root:
$ ifquery --list --allow auto
lo
eth0
