Message-Id: <20140704221424.860936698@linuxfoundation.org> Date: Fri, 4 Jul 2014 15:14:44 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Anton Blanchard <anton@...ba.org>, Benjamin Herrenschmidt <benh@...nel.crashing.org> Subject: [PATCH 3.15 45/66] powerpc: 64bit sendfile is capped at 2GB 3.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Anton Blanchard <anton@...ba.org> commit 5d73320a96fcce80286f1447864c481b5f0b96fa upstream. commit 8f9c0119d7ba (compat: fs: Generic compat_sys_sendfile implementation) changed the PowerPC 64bit sendfile call from sys_sendile64 to sys_sendfile. Unfortunately this broke sendfile of lengths greater than 2G because sys_sendfile caps at MAX_NON_LFS. Restore what we had previously which fixes the bug.
