nfs: if we have no valid attrs, then don't declare the attribute cache valid
commit c812012f9ca7cf89c9e1a1cd512e6c3b5be04b85 upstream. If we pass in an empty nfs_fattr struct to nfs_update_inode, it will (correctly) not update any of the attributes, but it then clears the NFS_INO_INVALID_ATTR flag, which indicates that the attributes are up to date. Don't clear the flag if the fattr struct has no valid attrs to apply.

nfs: Fix use of uninitialized variable in nfs_getattr()
commit 16caf5b6101d03335b386e77e9e14136f989be87 upstream. Variable 'err' needn't be initialized when nfs_getattr() uses it to check whether it should call generic_fillattr() or not.

removed, as upstream has moved the definition to list.h. The implementation
of list_next_entry was identical between the two.
irq.c, for both arm and arm64 architecture, has had its calls to
__irq_set_affinity_locked updated to reflect changes to the API upstream.

NFS: Don't declare inode uptodate unless all attributes were checked
commit 43b6535e717d2f656f71d9bd16022136b781c934 upstream. Fix a bug, whereby nfs_update_inode() was declaring the inode to be up to date despite not having checked all the attributes. The bug occurs because the temporary variable in which we cache the validity information is 'sanitised' before reapplying to nfsi->cache_validity.

The client had previously found a directory dentry. It then later tried to do an atomic open on a new (regular file) dentry. The attributes it got back had the same filehandle as the previously found directory inode. It then tried to put the filp because it failed the aops tests for O_DIRECT opens, and oopsed here because the ctx was still NULL. Obviously the root cause here is a server issue, but we can take steps to mitigate this on the client. When nfs_fhget is called, we always know what type of inode it is. In the event that there's a broken or malicious server on the other end of the wire, the client can end up crashing because the wrong ops are set on it. Have nfs_find_actor check that the inode type is correct after checking the fileid. The fileid check should rarely ever match, so it should only rarely ever get to this check. In the case where we have a broken server, we may see two different inodes with the same i_ino, but the client should be able to cope with them without crashing.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace and namespace infrastructure changes from Eric W Biederman: "This set of changes starts with a few small enhnacements to the user namespace. reboot support, allowing more arbitrary mappings, and support for mounting devpts, ramfs, tmpfs, and mqueuefs as just the user namespace root. I do my best to document that if you care about limiting your unprivileged users that when you have the user namespace support enabled you will need to enable memory control groups. There is a minor bug fix to prevent overflowing the stack if someone creates way too many user namespaces. The bulk of the changes are a continuation of the kuid/kgid push down work through the filesystems. These changes make using uids and gids typesafe which ensures that these filesystems are safe to use when multiple user namespaces are in use. The filesystems converted for 3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The changes for these filesystems were a little more involved so I split the changes into smaller hopefully obviously correct changes. XFS is the only filesystem that remains. I was hoping I could get that in this release so that user namespace support would be enabled with an allyesconfig or an allmodconfig but it looks like the xfs changes need another couple of days before it they are ready." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (93 commits) cifs: Enable building with user namespaces enabled. cifs: Convert struct cifs_ses to use a kuid_t and a kgid_t cifs: Convert struct cifs_sb_info to use kuids and kgids cifs: Modify struct smb_vol to use kuids and kgids cifs: Convert struct cifsFileInfo to use a kuid cifs: Convert struct cifs_fattr to use kuid and kgids cifs: Convert struct tcon_link to use a kuid. cifs: Modify struct cifs_unix_set_info_args to hold a kuid_t and a kgid_t cifs: Convert from a kuid before printing current_fsuid cifs: Use kuids and kgids SID to uid/gid mapping cifs: Pass GLOBAL_ROOT_UID and GLOBAL_ROOT_GID to keyring_alloc cifs: Use BUILD_BUG_ON to validate uids and gids are the same size cifs: Override unmappable incoming uids and gids nfsd: Enable building with user namespaces enabled. nfsd: Properly compare and initialize kuids and kgids nfsd: Store ex_anon_uid and ex_anon_gid as kuids and kgids nfsd: Modify nfsd4_cb_sec to use kuids and kgids nfsd: Handle kuids and kgids in the nfs4acl to posix_acl conversion nfsd: Convert nfsxdr to use kuids and kgids nfsd: Convert nfs3xdr to use kuids and kgids ... |

NFS: Use FS-Cache invalidation
Use the new FS-Cache invalidation facility from NFS to deal with foreign changes being detected on the server rather than attempting to retire the old cookie and get a new one. The problem with the old method was that NFS did not wait for all outstanding storage and retrieval ops on the cache to complete. There was no automatic wait between the calls to ->readpages() and calls to invalidate_inode_pages2() as the latter can only wait on locked pages that have been added to the pagecache (which they haven't yet on entry to ->readpages()). This was leading to oopses like the one below when an outstanding read got cut off from its cookie by a premature release.

NFS: add nfs_sb_deactive_async to avoid deadlock
Use nfs_sb_deactive_async instead of nfs_sb_deactive when in a workqueue context. This avoids a deadlock where rpc_shutdown_client loops forever in a workqueue kworker context, trying to kill all RPC tasks associated with the client, while one or more of these tasks have already been assigned to the same kworker (and will never run rpc_exit_task). This approach is needed because RPC tasks that have already been assigned to a kworker by queue_work cannot be canceled, as explained in the comment for workqueue.c:insert_wq_barrier.

fs: push rcu_barrier() from deactivate_locked_super() to filesystems
There's no reason to call rcu_barrier() on every deactivate_locked_super(). We only need to make sure that all delayed rcu free inodes are flushed before we destroy related cache. Removing rcu_barrier() from deactivate_locked_super() affects some fast paths. E.g. on my machine exit_group() of a last process in IPC namespace takes 0.07538s. rcu_barrier() takes 0.05188s of that time. Signed-off-by: Kirill A.

nfs: disable data cache revalidation for swapfiles
The VM does not like PG_private set on PG_swapcache pages. As suggested by Trond in http://lkml.org/lkml/2006/8/25/348, this patch disables NFS data cache revalidation on swap files. as it does not make sense to have other clients change the file while it is being used as swap. This avoids setting PG_private on swap pages, since there ought to be no further races with invalidate_inode_pages2() to deal with. Since we cannot set PG_private we cannot use page->private which is already used by PG_swapcache pages to store the nfs_page. Thus augment the new nfs_page_find_request logic.

NFS client updates for Linux 3.5
New features include:
- Rewrite the O_DIRECT code so that it can share the same coalescing and
pNFS functionality as the page cache code.
- Allow the server to provide hints as to when we should use pNFS, and
when it is more efficient to read and write through the metadata
server.
- NFS cache consistency updates:
- Use the ctime to emulate a change attribute for NFSv2/v3 so that
all NFS versions can share the same cache management code.
- New cache management code will only look at the change attribute
and size attribute when deciding whether or not our cached data
is still valid or not.
- Don't request NFSv4 post-op attributes on writes in cases such as
O_DIRECT, where we don't care about data cache consistency, or
when we have a write delegation, and know that our cache is
still consistent.
- Don't request NFSv4 post-op attributes on operations such as
COMMIT, where there are no expected metadata updates.
- Don't request NFSv4 directory post-op attributes in cases where
the operations themselves already return change attribute updates:
i.e. operations such as OPEN, CREATE, REMOVE, LINK and RENAME.
- Speed up 'ls' and friends by using READDIR rather than READDIRPLUS
if we detect no attempts to lookup filenames.
- Improve the code sharing between NFSv2/v3 and v4 mounts
- NFSv4.1 state management efficiency improvements
- More patches in preparation for NFSv4/v4.1 migration functionality.

vfs: Rename end_writeback() to clear_inode()
After we moved inode_sync_wait() from end_writeback() it doesn't make sense to call the function end_writeback() anymore. Rename it to clear_inode() which well says what the function really does - set I_CLEAR flag. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Fengguang Wu <fengguang.wu@intel.com> |

NFS: Adapt readdirplus to application usage patterns
While the use of READDIRPLUS is significantly more efficient than
READDIR followed by many LOOKUP calls, it is still less efficient
than just READDIR if the attributes are not required.
This patch tracks when lookups are attempted on the directory,
and uses that information to selectively disable READDIRPLUS
on that directory.
The first 'readdir' call is always served using READDIRPLUS.
Subsequent calls only use READDIRPLUS if there was a successful
lookup or revalidation on a child in the mean time.
Credit for the original idea should go to Neil Brown. See:
http://www.spinics.net/lists/linux-nfs/msg19996.html
However, the implementation in this patch differs from Neil's
in that it focuses on tracking lookups rather than calls to
stat().

NFS: Simplify the cache invalidation code
Now that NFSv2 and NFSv3 have simulated change attributes, instead of using all three of mtime, ctime and change attribute to manage data cache consistency, we can simplify the code to just use the change attribute. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> |

NFS: Simplify nfs_fhget()
If the inode is being initialised, there is no point in setting flags such as NFS_INO_INVALID_ACCESS, NFS_INO_INVALID_ACL or NFS_INO_INVALID_DATA since there are no cached access calls, acls or data caches to invalidate. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> |

NFS: create struct nfs_commit_info
It is COMMIT that is handled the most differently between the paged and direct paths. Create a structure that encapsulates everything either path needs to know about the commit state. We could use void to hide some of the layout driver stuff, but Trond suggests pulling it out to ensure type checking, given the huge changes being made, and the fact that it doesn't interfere with other drivers.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system
Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..
