NFSv4: Save the owner/group name string when doing open

2012-01-07T18:22:46Z

...so that we can do the uid/gid mapping outside the asynchronous RPC context. This fixes a bug in the current NFSv4 atomic open code where the client isn't able to determine what the true uid/gid fields of the file are, (because the asynchronous nature of the OPEN call denies it the ability to do an upcall) and so fills them with default values, marking the inode as needing revalidation. Unfortunately, in some cases, the VFS will do some additional sanity checks on the file, and may override the server's decision to allow the open because it sees the wrong owner/group fields.

NFSv4: Send unmapped uid/gids to the server when using auth_sys

2011-03-11T20:39:27Z

The new behaviour is enabled using the new module parameter 'nfs4_disable_idmapping'. Note that if the server rejects an unmapped uid or gid, then the client will automatically switch back to using the idmapper. Signed-off-by: Trond Myklebust

nfs: testing the wrong variable

The intent was to test "*desc" for allocation failures, but it tests "desc" which is always a valid pointer here. Signed-off-by: Dan Carpenter Signed-off-by: Trond Myklebust

NFS: new idmapper

2010-10-07T22:48:49Z

This patch creates a new idmapper system that uses the request-key function to place a call into userspace to map user and group ids to names. The old idmapper was single threaded, which prevented more than one request from running at a single time. This means that a user would have to wait for an upcall to finish before accessing a cached result. The upcall result is stored on a keyring of type id_resolver. See the file Documentation/filesystems/nfs/idmapper.txt for instructions.
