Date: Wed, 15 Jul 2015 18:09:16 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Chuck Lever <chuck.lever@...cle.com>, Trond Myklebust <trond.myklebust@...marydata.com>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.19.y-ckt 235/251] NFS: Fix size of NFSACL SETACL operations 3.19.8-ckt4 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Chuck Lever <chuck.lever@...cle.com> commit d683cc49daf7c5afca8cd9654aaa1bf63cdf2ad9 upstream. When encoding the NFSACL SETACL operation, reserve just the estimated size of the ACL rather than a fixed maximum. This eliminates needless zero padding on the wire that the server ignores. Fixes: ee5dc7732bd5 ('NFS: Fix "kernel BUG at fs/nfs/nfs3xdr.c:1338!"')
