From ff06dffbc8abfc60d6a0332f058f1d1bb01abb31 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 22 May 2012 17:53:19 -0700 Subject: sparc: Add full proper error handling to strncpy_from_user(). Linus removed the end-of-address-space hackery from fs/namei.c:do_getname() so we really have to validate these edge conditions and cannot cheat any more (as x86 used to as well). Move to a common C implementation like x86 did. And if both src and dst are sufficiently aligned we'll do word at a time copies and checks as well. Signed-off-by: David S.
