[PATCH 0/5 v2] fs: Avoid premature clearing of file capabilities

[Jan Kara <jack@xxxxxxx>]

Hello,

this patch series is my attempt to fix an issue when user can clear capabilites
of arbitrary file he can look up for example by running chown on it (this got
assigned CVE-2015-1350). The problem is that we call security_inode_killpriv()
before checking permissions in inode_change_ok(). This patch set moves that
call into inode_change_ok() after permissions are checked - the only trouble is
that we need to give dentry instead of inode there and that is not completely
trivial in some cases - I'm still missing a review from Ceph people to verify I
didn't miss anything.

Anyway, I guess the changes are fine for merging. Al, you please merge the
patches? Thanks!
