Please pull the following nfsd and file-locking changes from the for-3.5
branch at:
git://linux-nfs.org/~bfields/linux.git for-3.5
Sorry this is a bit late. In fact I still have a review backlog (at a
minimum some bugfixes), so will send a second pull later.
This includes patches addressing a long-standing problem in our NFSv4
implementation, which is that read delegations aren't broken on certain
local operations. (Hence a diffstat with a few lines in namei.c and
attr.c). The problem isn't solved completely in the case of rename,
where a small race remains; the patches to fix that will come in from Al
Viro if they pass review. But there's no regression in nfsd behavior if
those patches don't make it in.
Other than that:
- From Stanislav Kinsbursky, a bunch of NFS containerization
work (still in progress).
- Fix a failure to process encrypted rpc's from Windows clients
and servers due to our (incorrect) failure to handle gss
tokens with rotated data.
- Fix some stuff caught by sparse (actual bugs are fairly
minor); thanks to Al for reminding me to add sparse to my
regular testing.
- Fixes for some protocol bugs in the procedures that establish
4.0 and 4.1 clients, and much cleaner code. (Thanks also to
Chuck for a bugfix here, and Bryan and Trond for finding
another bug.)
- Some cleanup and bugfixes from Jeff, Simo, and Dros.
