nfsd: permit unauthenticated stat of export root

2008-09-29T21:56:56+00:00

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.

nfsd: rename MAY_ flags

2008-06-23T17:02:50+00:00

Rename nfsd_permission() specific MAY_* flags to NFSD_MAY_* to make it clear, that these are not used outside nfsd, and to avoid name and number space conflicts with the VFS. [comment from hch: rename MAY_READ, MAY_WRITE and MAY_EXEC as well] Signed-off-by: Miklos Szeredi Signed-off-by: J. Bruce Fields

knfsd: Replace lock_kernel with a mutex for nfsd thread startup/shutdown locking.

2008-06-23T17:02:49+00:00

This removes the BKL from the RPC service creation codepath. The BKL really isn't adequate for this job since some of this info needs protection across sleeps. Also, add some comments to try and clarify how the locking should work and to make it clear that the BKL isn't necessary as long as there is adequate locking between tasks when touching the svc_serv fields.

nfsd: don't allow setting ctime over v4

2008-04-25T17:00:11+00:00

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
