[Bug 415632] Re: apparmor not properly handling file deletion on NFS
This seems to have been two issues, 1. AppArmor was enforcing tighter deleted file delegation semantics and 2. With the new hook placement under certain filesystems creation of files/nods was showing up as deleted paths. The attached patch is the proposed fix and a test kernel with the patch applied can be grabbed from http://kernel.ubuntu.com/~jj/linux-image-2.6.31-13-generic_2.6.31-13.43_amd64.deb -- apparmor not properly handling file deletion on NFS https://bugs.launchpad.net/bugs/415632 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Reducing to Medium for now as I am not sure if High is appropriate.
Please adjust as necessary.
** Summary changed:
- evince fails to open all PDF - grey screen

** Description changed:
- All PDFs I try and load with evince end with evince showing me a
- wonderful grey screen with no content, and the window controls as usual
- (Max/min/close). PDFs open just fine with xpdf. This was working until
- about a week ago
+ Deleted files on NFS are not being handled properly. This was
+ demonstrated with the evince profile, but could happen with any confined
