Linus Torvalds 860448cf76 Merge branch 'for-4.1' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields:
 "A quiet cycle this time; this is basically entirely bugfixes.

  The few that aren't cc'd to stable are cleanup or seemed unlikely to
  affect anyone much"

* 'for-4.1' of git://linux-nfs.org/~bfields/linux:
  uapi: Remove kernel internal declaration
  nfsd: fix nsfd startup race triggering BUG_ON
  nfsd: eliminate NFSD_DEBUG
  nfsd4: fix READ permission checking
  nfsd4: disallow SEEK with special stateids
  nfsd4: disallow ALLOCATE with special stateids
  nfsd: add NFSEXP_PNFS to the exflags array
  nfsd: Remove duplicate macro define for max sec label length
  nfsd: allow setting acls with unenforceable DENYs
  nfsd: NFSD_FAULT_INJECTION depends on DEBUG_FS
  nfsd: remove unused status arg to nfsd4_cleanup_open_state
  nfsd: remove bogus setting of status in nfsd4_process_open2
  NFSD: Use correct reply size calculating function
  NFSD: Using path_equal() for checking two paths

depends on MULTIUSER
help
Choose Y here if you want to allow other computers to access
files residing on this system using Sun's Network File System
protocol. To compile the NFS server support as a module,
choose M here: the module will be called nfsd.
You may choose to use a user-space NFS server instead, in which
case you can choose N here.
To export local file systems using NFS, you also need to install
user space programs which can be found in the Linux nfs-utils
package, available from http://linux-nfs.org/. More detail about
the Linux NFS server implementation is available via the
exports(5) man page.
Below you can choose which versions of the NFS protocol are
available to clients mounting the NFS server on this system.
Support for NFS version 2 (RFC 1094) is always available when
CONFIG_NFSD is selected.
If unsure, say N.
config NFSD_V2_ACL
bool
depends on NFSD
config NFSD_V3
bool "NFS server support for NFS version 3"
depends on NFSD
help
This option enables support in your system's NFS server for
version 3 of the NFS protocol (RFC 1813).
If unsure, say Y.
config NFSD_V3_ACL
bool "NFS server support for the NFSv3 ACL protocol extension"
depends on NFSD_V3
select NFSD_V2_ACL
help
Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
never became an official part of the NFS version 3 protocol.
This protocol extension allows applications on NFS clients to
manipulate POSIX Access Control Lists on files residing on NFS
servers. NFS servers enforce POSIX ACLs on local files whether
this protocol is available or not.
This option enables support in your system's NFS server for the
NFSv3 ACL protocol extension allowing NFS clients to manipulate
POSIX ACLs on files exported by your system's NFS server. NFS
clients which support the Solaris NFSv3 ACL protocol can then
access and modify ACLs on your NFS server.
To store ACLs on your NFS server, you also need to enable ACL-
related CONFIG options for your local file systems of choice.
If unsure, say N.
config NFSD_V4
bool "NFS server support for NFS version 4"
depends on NFSD && PROC_FS
select NFSD_V3
select FS_POSIX_ACL
select SUNRPC_GSS
select CRYPTO
select GRACE_PERIOD
help
This option enables support in your system's NFS server for
version 4 of the NFS protocol (RFC 3530).
To export files using NFSv4, you need to install additional user
space programs which can be found in the Linux nfs-utils package,
available from http://linux-nfs.org/.
If unsure, say N.
config NFSD_PNFS
bool "NFSv4.1 server support for Parallel NFS (pNFS)"
depends on NFSD_V4
help
This option enables support for the parallel NFS features of the
minor version 1 of the NFSv4 protocol (RFC5661) in the kernel's NFS
server.
If unsure, say N.
config NFSD_V4_SECURITY_LABEL
bool "Provide Security Label support for NFSv4 server"
depends on NFSD_V4 && SECURITY
help
Say Y here if you want enable fine-grained security label attribute
support for NFS version 4. Security labels allow security modules like
SELinux and Smack to label files to facilitate enforcement of their policies.
Without this an NFSv4 mount will have the same label on each file.
If you do not wish to enable fine-grained security labels SELinux or
Smack policies on NFSv4 files, say N.
config NFSD_FAULT_INJECTION
bool "NFS server manual fault injection"
depends on NFSD_V4 && DEBUG_KERNEL && DEBUG_FS
help
This option enables support for manually injecting faults
into the NFS server. This is intended to be used for
testing error recovery on the NFS client.
If unsure, say N.
