Description Johannes Segitz 2014-11-03 09:56:56 UTC

rh#1159313

Linux kernel built with Virtual File System(VFS) support is vulnerable to a
deadlock condition. It occurs due to incorrect usage of file system locks.

An unprivileged user/process could use this flaw to render the system unusable, thus resulting in DoS.

Comment 1 Jiri Slaby 2015-01-12 09:18:10 UTC

Any updates here?

http://thread.gmane.org/gmane.linux.kernel.stable/119766

Comment 2 Miklos Szeredi 2015-01-14 09:25:37 UTC

Workin on the backport...

Comment 3 Miklos Szeredi 2015-01-14 16:32:21 UTC

The first patch (946e51f2bf37 "move d_rcu from overlapping d_child to overlapping d_alias") will make the kabi checker complain, since the d_rcu field in struct dentry is moved from being a union with d_child to being a union with d_alias.

I think we can just revert the actual move of d_rcu for the kabi generator, since nobody outside fs/dcache.c should ever be using d_rcu directly, and the other fields remain at the same position and size (struct rcu_head is two pointers, just like struct list_head and struct hlist_node).

But I'm not sure this sort of trickery is allowed.

Michal?

Comment 4 Michal Marek 2015-01-14 16:55:08 UTC

Can you please bring it up on the kernel mailing list. At first look I would say no, because it's not just the union change, but also the layout and size of struct dentry.

Comment 5 Miklos Szeredi 2015-01-21 16:11:19 UTC

Fixes pushed to:

SLE11-SP3

Comment 16 Michal Hocko 2015-05-04 07:13:41 UTC

Forgot to mention this doesn't affect SLE11-SP1-TD and older TD branches as it has been introduced by 58db63d08679 in 2.6.38-rc1. (http://thread.gmane.org/gmane.linux.kernel.stable/119766).
