From: Jan Kara Subject: [PATCH 0/4] ext4: Fix overflows in ext4 code Date: Wed, 29 May 2013 14:05:29 +0200 Message-ID: <1369829133-4307-1-git-send-email-jack@suse.cz> Cc: linux-ext4@vger.kernel.org To: Ted Tso Return-path: Received: from cantor2.suse.de ([195.135.220.15]:52120 "EHLO mx2.suse.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S965866Ab3E2MFl (ORCPT ); Wed, 29 May 2013 08:05:41 -0400 Sender: linux-ext4-owner@vger.kernel.org List-ID: Hello, while working on my patchset, I stumbled over an overflow bug which made me do a quick audit of shifts in ext4 code. I've found a couple of places which use << and which can overflow (usually on 32-bit architecture only but at least SEEK_HOLE / SEEK_DATA bugs are real even for 64-bit architectures). Patches in this series fix the issues I've found. Likely this is also stable material so Ted, you might want to add stable@vger.kernel.org to CC when merging the patches. Honza
