Subject: [PATCH 0/4] ext4: Fix overflows in ext4 code
Date: Wed, 29 May 2013 14:05:29 +0200	[thread overview]
Message-ID: <1369829133-4307-1-git-send-email-jack@suse.cz> (raw)


  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.
