NFS: Add SECINFO_NO_NAME procedure

2011-07-12T17:40:27Z

If the client is using NFS v4.1, then we can use SECINFO_NO_NAME to find the secflavor for the initial mount. If the server doesn't support SECINFO_NO_NAME then I fall back on the "guess and check" method used for v4.0 mounts. Signed-off-by: Bryan Schumaker Signed-off-by: Trond Myklebust

NFS: Remove unused argument from nfs_find_best_sec()

2011-04-12T23:34:23Z

The inode was used in an earlier version of the code, but it isn't used anymore. Signed-off-by: Bryan Schumaker Signed-off-by: Trond Myklebust

NFS: Fix a signed vs. unsigned secinfo bug

2011-04-06T20:25:04Z

rpc_authflavor_t is cast from an unsigned int, but the initial code tried to use it as a signed int. I fix this by passing an rpc_authflavor_t pointer around, and returning signed integers from functions. Signed-off-by: Bryan Schumaker Reported-by: Dan Carpenter Signed-off-by: Trond Myklebust

NFS: use secinfo when crossing mountpoints

2011-03-24T17:52:42Z

A submount may use different security than the parent mount does. We should figure out what sec flavor the submount uses at mount time. Signed-off-by: Bryan Schumaker Signed-off-by: Trond Myklebust

NFS: lookup supports alternate client

2011-03-24T17:52:41Z

A later patch will need to perform a lookup using an alternate client with a different security flavor. This patch adds support for doing that on NFS v4. Signed-off-by: Bryan Schumaker Signed-off-by: Trond Myklebust

nfs: lock() vs unlock() typo

2011-03-21T04:45:50Z

These should be spin_unlock() instead of spin_lock(). It's a typo. Signed-off-by: Dan Carpenter Signed-off-by: Al Viro

nfs: nfs_do_{ref,sub}mount() superblock argument is redundant

nfs: make nfs_path() work without vfsmount

2011-03-16T20:47:55Z

part 3: now we have everything to get nfs_path() just by dentry - just follow to (disconnected) root and pick the rest of the thing there. Start killing propagation of struct vfsmount * on the paths that used to bring it to nfs_path(). Signed-off-by: Al Viro

Unexport do_add_mount() and add in follow_automount(), not ->d_automount()

2011-01-16T01:07:48Z

Unexport do_add_mount() and make ->d_automount() return the vfsmount to be added rather than calling do_add_mount() itself. follow_automount() will then do the addition. This slightly complicates things as ->d_automount() normally wants to add the new vfsmount to an expiration list and start an expiration timer. The problem with that is that the vfsmount will be deleted if it has a refcount of 1 and the timer will not repeat if the expiration list is empty. To this end, we require the vfsmount to be returned from d_automount() with a refcount of (at least) 2. One of these refs will be dropped unconditionally. In addition, follow_automount() must get a 3rd ref around the call to do_add_mount() lest it eat a ref and return an error, leaving the mount we have open to being expired as we would otherwise have only 1 ref on it. d_automount() should also add the the vfsmount to the expiration list (by calling mnt_set_expiry()) and start the expiration timer before returning, if this mechanism is to be used. The vfsmount will be unlinked from the expiration list by follow_automount() if do_add_mount() fails. This patch also fixes the call to do_add_mount() for AFS to propagate the mount flags from the parent vfsmount. Signed-off-by: David Howells Signed-off-by: Al Viro
