| H A D | nfs4xdr.c | 519d3959 Tue Aug 14 16:30:10 CDT 2012 Trond Myklebust <Trond.Myklebust@netapp.com> NFSv4: Fix pointer arithmetic in decode_getacl
Resetting the cursor xdr->p to a previous value is not a safe
practice: if the xdr_stream has crossed out of the initial iovec,
then a bunch of other fields would need to be reset too.
Fix this issue by using xdr_enter_page() so that the buffer gets
page aligned at the bitmap _before_ we decode it.
Also fix the confusion of the ACL length with the page buffer length
by not adding the base offset to the ACL length...
