From: Sachin Prabhu Date: Thu, 22 Mar 2012 16:46:28 +0000 Subject: [PATCH] Fix length of buffer copied in __nfs4_get_acl_uncached commit 20e0fa98b751facf9a1101edaefbc19c82616a68 upstream. _copy_from_pages() used to copy data from the temporary buffer to the user passed buffer is passed the wrong size parameter when copying data. res.acl_len contains both the bitmap and acl lenghts while acl_len contains the acl length after adjusting for the bitmap size.
