[GIT PULL] Keyrings (& NFS) fixes

From: David Howells
Date: Fri Nov 21 2014 - 16:53:34 EST

Hi James,

Can you pass these patches on to Linus please?

The first one fixes the handling of maximum buffer size for key descriptions,
fixing the size at 4095 + NUL char rather than whatever PAGE_SIZE happens to
be and permits you to read back the full description without it getting
clipped because some extra information got prepended.

The second and third fix a bug in NFS idmapper handling whereby a key
representing a mapping between an id and a name expires and causing
EKEYEXPIRED to be seen internally in NFS (which prevents the mapping from
happening) rather than re-looking up the mapping.

The following changes since commit a6aacbde406eeb6f8fc218b2c6172825f5e73fcf:

Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity into next (2014-11-19 21:36:07 +1100)
