From 863abad4f644b6c12bc8176206b35fa7e7cfe1a9 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sat, 30 Oct 2010 18:37:16 +0200 Subject: [PATCH] MIPS: VPE loader: Check vmalloc return value in vpe_open The return value of the vmalloc() call in arch/mips/kernel/vpe.c::vpe_open() is not checked, so we potentially store a null pointer in v->pbuffer. Add a check for a null return and then return -ENOMEM in that case. [Ralf: The check added by Jesper's original patch is where it logically should be. Adding it eleminated the need for the checks in a few other places, so I removed them. There still is a zillion of other things that need to be fixed in this file / API.] Signed-off-by: Jesper Juhl Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/1747/ Signed-off-by: Ralf Baechle --- Reading git-format-patch failed
