nfsd: take struct file setup fully into nfs4_preprocess_stateid_op

2015-06-22T18:15:03+00:00

This patch changes nfs4_preprocess_stateid_op so it always returns a valid struct file if it has been asked for that. For that we now allocate a temporary struct file for special stateids, and check permissions if we got the file structure from the stateid. This ensures that all callers will get their handling of special stateids right, and avoids code duplication. There is a little wart in here because the read code needs to know if we allocated a file structure so that it can copy around the read-ahead parameters. In the long run we should probably aim to cache full file structures used with special stateids instead. Signed-off-by: Christoph Hellwig Signed-off-by: J. Bruce Fields

nfsd: clean up raparams handling

2015-06-19T19:39:51+00:00

Refactor the raparam hash helpers to just deal with the raparms, and keep opening/closing files separate from that. Signed-off-by: Christoph Hellwig Signed-off-by: J. Bruce Fields

nfsd: Add ALLOCATE support

2014-11-07T21:19:49+00:00

The ALLOCATE operation is used to preallocate space in a file. I can do this by using vfs_fallocate() to do the actual preallocation. ALLOCATE only returns a status indicator, so we don't need to write a special encode() function. Signed-off-by: Anna Schumaker Signed-off-by: J. Bruce Fields

NFSD: Remove iattr parameter from nfsd_symlink()

2014-07-08T21:14:31+00:00

Commit db2e747b1499 (vfs: remove mode parameter from vfs_symlink()) have remove mode parameter from vfs_symlink. So that, iattr isn't needed by nfsd_symlink now, just remove it. Signed-off-by: Kinglong Mee Signed-off-by: J. Bruce Fields

nfsd: let nfsd_symlink assume null-terminated data

2014-07-08T21:14:23+00:00

Currently nfsd_symlink has a weird hack to serve callers who don't null-terminate symlink data: it looks ahead at the next byte to see if it's zero, and copies it to a new buffer to null-terminate if not. That means callers don't have to null-terminate, but they *do* have to ensure that the byte following the end of the data is theirs to read. That's a bit subtle, and the NFSv4 code actually got this wrong. So let's just throw out that code and let callers pass null-terminated strings; we've already fixed them to do that. Signed-off-by: J.

nfsd: nfsd_splice_read and nfsd_readv should return __be32

2014-06-23T15:31:37+00:00

The callers expect a __be32 return and the functions they call return __be32, so having these return int is just wrong. Also, nfsd_finish_read can be made static. Signed-off-by: Jeff Layton Reviewed-by: Christoph Hellwig Signed-off-by: J. Bruce Fields
