* [PATCH] knfsd: nfsd4: better nfs4acl errorsNeilBrown2006-04-11
| | | | | | | | | | | | We're returning -1 in a few places in the NFSv4<->POSIX acl translation code where we could return a reasonable error. Also allows some minor simplification elsewhere.

* [PATCH] knfsd: nfsd4: Wrong error handling in nfs4aclNeilBrown2006-04-11
| | | | | | | | | | | | | this fixes coverity id #3. Coverity detected dead code, since the == -1 comparison only returns 0 or 1 to error. Therefore the if ( error < 0 ) statement was always false. Seems that this was an if( error = nfs4... ) statement some time ago, which got broken during cleanup. Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: J.

* [PATCH] knfsd: locks: flag NFSv4-owned locksNeilBrown2006-04-11
| | | | | | | | | | | | | | | | | | | | | | | | Use the fl_lmops field to identify which locks are ours, instead of trying to look them up in our private hash. This is safer and more efficient. Earlier versions of this patch used a lock flag instead, but Trond pointed out that adding a new flag for each lock manager wasn't going to scale well, and suggested this approach instead; a separate patch converts lockd to using fl_lmops in the same way. In the NFSv4 case this looks like a bit of a hack, since the NFSv4 server isn't currently actually defining a lock_manager_operations struct, so we end up defining one *just* to serve as a cookie to identify our locks. But it works, and we actually do expect to start using the lock_manager_operations at some point anyway.

* [PATCH] knfsd: Correct reserved reply space for read requests.NeilBrown2006-04-11
| | | | | | | | | | | | | | | | | | | | | NFSd makes sure there is enough space to hold the maximum possible reply before accepting a request. The units for this maximum is (4byte) words. However in three places, particularly for read request, the number given is a number of bytes. This means too much space is reserved which is slightly wasteful. This is the sort of patch that could uncover a deeper bug, and it is not critical, so it would be best for it to spend a while in -mm before going in to mainline.

| | | | | | | | | | | | | | This is a conversion to make the various file_operations structs in fs/ const. Basically a regexp job, with a few manual fixups The goal is both to increase correctness (harder to accidentally write to shared datastructures) and reducing the false sharing of cachelines with things that get dirty in .data (while .rodata is nicely read only and thus cache clean) Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] knfsd: Break the hard linkage from svc_expkey to svc_exportNeilBrown2006-03-27
| | | | | | | | | | | | | | | | Current svc_expkey holds a pointer to the svc_export structure, so updates to that structure have to be in-place, which is a wart on the whole cache infrastruct. So we break that linkage and just do a second lookup. If this became a performance issue, it would be possible to put a direct link back in which was only used conditionally. i.e. when an object is replaced in the cache, we set a flag in the old object. When dereferencing the link from svc_expkey, if the flag is set, we drop the reference and do a fresh lookup.

| | | | | | | | | | | | | | | Logic fixes for LOCK and UNLOCK. - Move the permission check on the current file handle outside of nfs4_lock_state() - remove the file manager fl_release_private calls; fl_ops is not set.

* [PATCH] nfsd: remove inline from a couple of large NFS functionsNeilBrown2006-01-18
| | | | | | | | | | These are both called from two places close together. I could rearrange that code so there is only one call site, but just removing the 'inline' is probably best.

* [PATCH] nfsd: check error status from nfsd_sync_dirYAMAMOTO Takashi2006-01-18
| | | | | | | | | | | | | | | | | Change nfsd_sync_dir to return an error if ->sync fails, and pass that error up through the stack. This involves a number of rearrangements of error paths, and care to distinguish between Linux -errno numbers and NFSERR numbers. In the 'create' routines, we continue with the 'setattr' even if a previous sync_dir failed. This patch is quite different from Takashi's in a few ways, but there is still a strong lineage.

* [PATCH] add vfs_* helpers for xattr operationsChristoph Hellwig2006-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add vfs_getxattr, vfs_setxattr and vfs_removexattr helpers for common checks around invocation of the xattr methods. NFSD already was missing some of the checks and there will be more soon. Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: James Morris <jmorris@namei.org> (James, I haven't touched selinux yet because it's doing various odd things and I'm not sure how it would interact with the security attribute fallbacks you added. Could you investigate whether it could use vfs_getxattr or if not add a __vfs_getxattr helper to share the bits it is fine with?) For NFSv4: instead of just converting it add an nfsd_getxattr helper for the code shared by NFSv2/3 and NFSv4 ACLs. In fact that code isn't even NFS-specific, but I'll wait for more users to pop up first before moving it to common code.

* [PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen2006-01-09
| | | | | | | | | | | | | This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different.
