[PATCH 3.15 45/66] powerpc: 64bit sendfile is capped at 2GB

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anton Blanchard <anton@xxxxxxxxx>

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.
