Remove unused arguments

2014-01-17T16:51:44+00:00

The name variable is always set to NULL now in all callers, so just
sto passing it around needlessly.
The uid_t variable is not used at all, so chuck it out too.

Improve first attempt at acquiring GSS credentials

2014-01-17T16:51:10+00:00

Since now rpc.gssd is swithing uid before attempting to acquire
credentials, we do not need to pass in the special uid-as-a-string name
to gssapi, because the process is already running under the user's
credentials.

By removing this code we can fix a class of false negatives where the
user name does not match the actual ccache credentials and the ccache
type used is not one of the only 2 supported explicitly by rpc.gssd by the
fallback trolling done later.

mountd: optimize libblkid usage

2014-01-07T20:57:48+00:00

 * use get_uuid_blkdev() only first time for the path (it means
   that uuid_by_path() is called with type==0)

 * don't use libblkid for btrfs, network or pseudo filesystems

Note that the patch defines the fs type ID rather than include
 as this file seems incomplete and libc specific).

exportfs.c: escape path for function test_export

2014-01-07T20:57:48+00:00

Verbatim patch proposal from J. Bruce Fields except calling
snprintf instead of sprintf.

Tested and appears to work with path names that have a space.

nfsd: fix minorversion-choosing interface

2014-01-07T20:57:48+00:00

From: "J. Bruce Fields" 

By unconditionally adding ?4.2 to the version string written to the
kernel we make nfs-utils incompatible with pre-4.2-supporting kernels.

Ditto for 4.1.  This problem was introduced by
12a590f8d556c00a9502eeebaa763d906222d521 "rpc.nfsd: Allow v4.2 server
support with the -V option", which also change nfsd to unconditionally
pass ?4.2.

Instead, just don't mention 4.1 or 4.2 unless the commandline has
specifically requested that one or the other be turned on or off.

exportfs: modify can_test() to use LONG_MAX when appropriate

2013-11-20T20:04:47+00:00

This patch is the nfs-utils patch corresponding to the kernel patch
commit 2f74f972 "sunrpc: prepare NFS for 2038". The kernel sunrpc
code needs to handle seconds since epoch greater than 2147483647.
This means functions that parse time as an int need to
handle it as time_t."

When appropriate exportfs should use LONG_MAX in can_test()
instead of INT_MAX.

nfs(5): Treatment of *atime mount options

2013-11-20T20:04:47+00:00

I was reminded recently that NFS treats file atime time stamps
differently than other filesystems.  It also ignores the generic
*atime mount options because it cannot support the atime semantics
of local filesystems.

We should document that somewhere.  nfs(5) seems like a logical
place for it.
