Subject: [PATCH] Fix length of buffer copied in __nfs4_get_acl_uncached
Date: Thu, 22 Mar 2012 16:46:28 +0000 [thread overview]
Message-ID: <1332434788.2377.1.camel@localhost> (raw)
_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.
