[PATCH] knfsd: add some new fsid types

2007-02-14T16:09:53+00:00

Add support for using a filesystem UUID to identify and export point in the filehandle. For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up too much room. For NFSv3+, we use the full 16 bytes, and possibly also a 64bit inode number for exports beneath the root of a filesystem. When generating an fsid to return in 'stat' information, use the UUID (hashed down to size) if it is available and a small 'fsid' was not specifically provided.

[PATCH] include/linux/nfsd/const.h: remove NFS_SUPER_MAGIC

[PATCH] knfsd: Fix type mismatch with filldir_t used by nfsd

2007-01-26T21:51:00+00:00

nfsd defines a type 'encode_dent_fn' which is much like 'filldir_t' except that the first pointer is 'struct readdir_cd *' rather than 'void *'. It then casts encode_dent_fn points to 'filldir_t' as needed. This hides any other type mismatches between the two such as the fact that the 'ino' arg recently changed from ino_t to u64. So: get rid of 'encode_dent_fn', get rid of the cast of the function type, change the first arg of various functions from 'struct readdir_cd *' to 'void *', and live with the fact that we have a little less type checking on the calling of these functions now. Less internal (to nfsd) checking offset by more external checking, which is more important. Thanks to Gabriel Paubert for discovering this and providing an initial patch.

[PATCH] knfsd: replace some warning ins nfsfh.h with BUG_ON or WARN_ON

2007-01-26T21:50:59+00:00

A couple of the warnings will be followed by an Oops if they ever fire, so may as well be BUG_ON. Another isn't obviously fatal but has never been known to fire, so make it a WARN_ON. Cc: Adrian Bunk Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: nfsd4: reorganize compound ops

2006-12-13T17:05:54+00:00

Define an op descriptor struct, use it to simplify nfsd4_proc_compound(). Signed-off-by: J. Bruce Fields Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: nfsd4: move replay_owner to cstate

2006-12-13T17:05:54+00:00

Tuck away the replay_owner in the cstate while we're at it. Signed-off-by: J. Bruce Fields Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: nfsd4: pass saved and current fh together into nfsd4 operations

2006-12-13T17:05:54+00:00

Pass the saved and current filehandles together into all the nfsd4 compound operations. I want a unified interface to these operations so we can just call them by pointer and throw out the huge switch statement. Also I'll eventually want a structure like this--that holds the state used during compound processing--for deferral. Signed-off-by: J.

[PATCH] knfsd: nfsd4: clarify units of COMPOUND_SLACK_SPACE

2006-12-13T17:05:53+00:00

A comment here incorrectly states that "slack_space" is measured in words, not bytes. Remove the comment, and adjust a variable name and a few comments to clarify the situation. This is pure cleanup; there should be no change in functionality. Signed-off-by: J. Bruce Fields Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] nfsd4: fix open-create permissions

2006-11-09T02:29:23+00:00

In the case where an open creates the file, we shouldn't be rechecking permissions to open the file; the open succeeds regardless of what the new file's mode bits say. This patch fixes the problem, but only by introducing yet another parameter to nfsd_create_v3. This is ugly. This will be fixed by later patches. Signed-off-by: J.

[PATCH] nfsd: nfs_replay_me

2006-10-20T17:26:43+00:00

We are using NFS_REPLAY_ME as a special error value that is never leaked to clients. That works fine; the only problem is mixing host- and network- endian values in the same objects. Network-endian equivalent would work just as fine; switch to it. Signed-off-by: Al Viro Acked-by: Trond Myklebust Acked-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
