From 30cff1ffff3981c8d96dc33870b652e70190ba37 Mon Sep 17 00:00:00 2001 From: Benny Halevy Date: Wed, 2 Jul 2008 11:13:18 +0300 Subject: [PATCH] nfsd: return nfserr_minor_vers_mismatch when compound minorversion != 0 Check minorversion once before decoding any operation and reject with nfserr_minor_vers_mismatch if != 0 (this still happens in nfsd4_proc_compound). In this case return a zero length resultdata array as required by RFC3530. minorversion 1 processing will have its own vector of decoders. Signed-off-by: Benny Halevy Signed-off-by: J.
