2015-05-07nfsd: stop READDIRPLUS returning inconsistent attributesNeilBrown
The NFSv3 READDIRPLUS gets some of the returned attributes from the readdir, and some from an inode returned from a new lookup. The two objects could be different thanks to intervening renames. The attributes in READDIRPLUS are optional, so let's just skip them if we notice this case. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2013-12-10nfsd: don't return high mode bitsAlbert Fluegel
The Linux NFS server replies among other things to a "Check access permission" the following: NFS: File type = 2 (Directory) NFS: Mode = 040755 A netapp server replies here: NFS: File type = 2 (Directory) NFS: Mode = 0755 The RFC 1813 i read: fattr3 struct fattr3 { ftype3 type; mode3 mode; uint32 nlink; ... For the mode bits only the lowest 9 are defined in the RFC As far as I can tell, knfsd has always done this, so apparently it's harmless. Nevertheless, it appears to be wrong. Note this is already correct in the NFSv4 case, only v2 and v3 need fixing. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2010-12-08nfsd: Fix possible BUG_ON firing in set_change_infoNeil Brown
If vfs_getattr in fill_post_wcc returns an error, we don't set fh_post_change. For NFSv4, this can result in set_change_info triggering a BUG_ON. i.e. fh_post_saved being zero isn't really a bug. So: - instead of BUGging when fh_post_saved is zero, just clear ->atomic. - if vfs_getattr fails in fill_post_wcc, take a copy of i_ctime anyway. This will be used i seg_change_info, but not overly trusted. - While we are there, remove the pointless 'if' statements in set_change_info. There is no harm setting all the values.

2009-04-29nfsd: support ext4 i_versionJ. Bruce Fields
ext4 supports a real NFSv4 change attribute, which is bumped whenever the ctime would be updated, including times when two updates arrive within a jiffy of each other. (Note that although ext4 has space for nanosecond-precision ctime, the real resolution is lower: it actually uses jiffies as the time-source.) This ensures clients will invalidate their caches when they need to. There is some fear that keeping the i_version up-to-date could have performance drawbacks, so for now it's turned on only by a mount option. We hope to do something better eventually.

As of f34b95689d2ce001c "The NFSv2/NFSv3 server does not handle zero length WRITE request correctly", the xdr decode routines for NFSv2 and NFSv3 reject requests that aren't the right length, so krb5i (for example) WRITE requests can get lost.

2007-10-09knfsd: 64 bit ino support for NFS serverPeter Staubach
Modify the NFS server code to support 64 bit ino's, as appropriate for the system and the NFS protocol version. The gist of the changes is to query the underlying file system for attributes and not just to use the cached attributes in the inode. For this specific purpose, the inode only contains an ino field which unsigned long, which is large enough on 64 bit platforms, but is not large enough on 32 bit platforms. I haven't been able to find any reason why ->getattr can't be called while i_mutex. The specification indicates that i_mutex is not required to be held in order to invoke ->getattr, but it doesn't say that i_mutex can't be held while invoking ->getattr. I also haven't come to any conclusions regarding the value of lease_get_mtime() and whether it should or should not be invoked by fill_post_wcc() too. I chose not to change this because I thought that it was safer to leave well enough alone. If we decide to make a change, it can be done separately.

2007-05-09The NFSv2/NFSv3 server does not handle zero length WRITE requests correctlyPeter Staubach
The NFSv2 and NFSv3 servers do not handle WRITE requests for 0 bytes correctly. The specifications indicate that the server should accept the request, but it should mostly turn into a no-op. Currently, the server will return an XDR decode error, which it should not. Attached is a patch which addresses this issue. It also adds some boundary checking to ensure that the request contains as much data as was requested to be written. It also correctly handles an NFSv3 request which requests to write more data than the server has stated that it is prepared to handle. Previously, there was some support which looked like it should work, but wasn't quite right.

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.

2007-01-26[PATCH] knfsd: Fix type mismatch with filldir_t used by nfsdNeilBrown
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 <paubert@iram.es> for discovering this and providing an initial patch.

.. by allocating the array of 'kvec' in 'struct svc_rqst'. As we plan to increase RPCSVC_MAXPAGES from 8 upto 256, we can no longer allocate an array of this size on the stack. So we allocate it in 'struct svc_rqst'. However svc_rqst contains (indirectly) an array of the same type and size (actually several, but they are in a union). So rather than waste space, we move those arrays out of the separately allocated union and into svc_rqst to share with the kvec moved out of svc_tcp_recvfrom (various arrays are used at different times, so there is no conflict).

2006-10-04[PATCH] knfsd: Replace two page lists in struct svc_rqst with oneNeilBrown
We are planning to increase RPCSVC_MAXPAGES from about 8 to about 256. This means we need to be a bit careful about arrays of size RPCSVC_MAXPAGES. struct svc_rqst contains two such arrays. However the there are never more that RPCSVC_MAXPAGES pages in the two arrays together, so only one array is needed. The two arrays are for the pages holding the request, and the pages holding the reply. Instead of two arrays, we can simply keep an index into where the first reply page is. This patch also removes a number of small inline functions that probably server to obscure what is going on rather than clarify it, and opencode the needed functionality. Also remove the 'rq_restailpage' variable as it is *always* 0. i.e. if the response 'xdr' structure has a non-empty tail it is always in the same pages as the head. check counters are initilised and incr properly check for consistant usage of ++ etc maybe extra some inlines for common approach general review Signed-off-by: Neil Brown <neilb@suse.de> Cc: Magnus Maatta <novell@kiruna.se> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
