Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] NFSD: Add server support for NFSv3 ACLs. This adds functions for encoding and decoding POSIX ACLs for the NFSACL protocol extension, and the GETACL and SETACL RPCs. The implementation is compatible with NFSACL in Solaris.

nfsd: permit unauthenticated stat of export root RFC 2623 section 2.3.2 permits the server to bypass gss authentication checks for certain operations that a client may perform when mounting. In the case of a client that doesn't have some form of credentials available to it on boot, this allows it to perform the mount unattended. (Presumably real file access won't be needed until a user with credentials logs in.) Being slightly more lenient allows lots of old clients to access krb5-only exports, with the only loss being a small amount of information leaked about the root directory of the export. This affects only v2 and v3; v4 still requires authentication for all access. Thanks to Peter Staubach testing against a Solaris client, which suggesting addition of v3 getattr, to the list, and to Trond for noting that doing so exposes no additional information.

[PATCH] nfsd4: fix open-create permissions 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.

__be32 nfsd_write(struct svc_rqst *, struct svc_fh *,struct file *,
Short write in nfsd becomes a full write to the client If a filesystem being written to via NFS returns a short write count (as opposed to an error) to nfsd, nfsd treats that as a success for the entire write, rather than the short count that actually succeeded. For example, given a 8192 byte write, if the underlying filesystem only writes 4096 bytes, nfsd will ack back to the nfs client that all 8192 bytes were written. The nfs client does have retry logic for short writes, but this is never called as the client is told the complete write succeeded. There are probably other ways it could happen, but in my case it happened with a fuse (filesystem in userspace) filesystem which can rather easily have a partial write. Here is a patch to properly return the short write count to the client. Signed-off-by: David Shaw <dshaw@jabberwocky.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

__be32 nfsd_readdir(struct svc_rqst *, struct svc_fh *,
[PATCH] knfsd: Fix type mismatch with filldir_t used by nfsd 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.

nfsd: permit unauthenticated stat of export root RFC 2623 section 2.3.2 permits the server to bypass gss authentication checks for certain operations that a client may perform when mounting. In the case of a client that doesn't have some form of credentials available to it on boot, this allows it to perform the mount unattended. (Presumably real file access won't be needed until a user with credentials logs in.) Being slightly more lenient allows lots of old clients to access krb5-only exports, with the only loss being a small amount of information leaked about the root directory of the export. This affects only v2 and v3; v4 still requires authentication for all access.

knfsd: nfsd4: vary maximum delegation limit based on RAM size Our original NFSv4 delegation policy was to give out a read delegation on any open when it was possible to. Since the lifetime of a delegation isn't limited to that of an open, a client may quite reasonably hang on to a delegation as long as it has the inode cached. This becomes an obvious problem the first time a client's inode cache approaches the size of the server's total memory. Our first quick solution was to add a hard-coded limit. This patch makes a mild incremental improvement by varying that limit according to the server's total memory size, allowing at most 4 delegations per megabyte of RAM. My quick back-of-the-envelope calculation finds that in the worst case (where every delegation is for a different inode), a delegation could take about 1.5K, which would make the worst case usage about 6% of memory. The new limit works out to be about the same as the old on a 1-gig server.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

knfsd: move nfsv4 slab creation/destruction to module init/exit We have some slabs that the nfs4 server uses to store state objects. We're currently creating and destroying those slabs whenever the server is brought up or down. That seems excessive; may as well just do that in module initialization and exit. Also add some minor header cleanup. (Thanks to Andrew Morton for that and a compile fix.) Signed-off-by: "J. Bruce Fields" <bfields@citi.umich.edu> Acked-by: Neil Brown <neilb@suse.de>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

nfsd: don't allow setting ctime over v4 Presumably this is left over from earlier drafts of v4, which listed TIME_METADATA as writeable. It's read-only in rfc 3530, and shouldn't be modifiable anyway. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
