[GIT PULL] Keyrings (& NFS) fixes

From: David Howells
Date: Mon Dec 01 2014 - 18:16:59 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 009d0431c3914de64666bec0d350e54fdd59df6a:

Linux 3.18-rc7 (2014-11-30 16:42:27 -0800)
