-Subject:    [PATCH] nfsd: check for oversized NFSv2/v3 arguments
-
-A client can append random data to the end of an NFSv2 or NFSv3 RPC call
-without our complaining; we'll just stop parsing at the end of the
-expected data and ignore the rest.
-
-Encoded arguments and replies are stored together in an array of pages,
-and if a call is too large it could leave inadequate space for the
-reply.  This is normally OK because NFS RPC's typically have either
-short arguments and long replies (like READ) or long arguments and short
-replies (like WRITE).  But a client that sends an incorrectly long reply
-can violate those assumptions.  This was observed to cause crashes.
-
-So, insist that the argument not be any longer than we expect.
-
-Also, several operations increment rq_next_page in the decode routine
-before checking the argument size, which can leave rq_next_page pointing
-well past the end of the page array, causing trouble later in
-svc_free_pages.
-
-As followup we may also want to rewrite the encoding routines to check
-more carefully that they aren't running off the end of the page array.
