Univention Bugzilla – Bug 36990
NFS ACL NULL handling (3.2)
Last modified: 2014-12-08 06:25:16 CET
In errata 134 for UCS 3.2 we updated the Linux kernel to 3.10.46. 3.10.42 backported this upstream fix from 3.15: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=aa07c713ecfc0522916f3cd57ac628ea6127c0ec This triggers a NULL dereference in kernels < 3.14 and requires the following fix: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=5b6da64a7e447eadce0d3e201c0fd6f540f2ec93 (The patch isn't merged into 3.10.x yet, I'll contact Greg KH for that). The kernel in UCS 4.0 is not affected; the affected code was removed in 3.14. The (unsupported) kernel in UCS 3.1 isn't affected either; the regression was introduced in 3.2.60, which wasn't merged into UCS 3.1.
This is fixed with the patch 52-nfs-acl-null-pointer-deref.patch. YAML files: 2014-12-01-linux.yaml 2014-12-01-univention-kernel-image.yaml
OK: see Bug #35397 comment 17
