Bug Description

I had hard time setting cipso labels until I backtraced the bug and found fix from the
mainline kernel:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0fcfee61d63b82c1eefb5b1a914240480f17d63f

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1236743

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I'm developing a library called libsmack and found this issue by reading kernel code. Then I checked whether this issue is already fixed and found the commit ID mentioned in the description.

This bug is a off-by-one bug. Zero character ending the string describing the SMACK label is not properly skipped.

summary: - cipso2 file does not work correctly in raring kernel for precise LTS
+ SMACK LSM: cipso2 file does not work correctly in the raring kernel for
+ precise LTS
