Subject: Re: [PATCH] Fix possible memory corruption in xfs_readlink
Date: Wed, 2 Nov 2011 15:45:07 -0400 [thread overview]
Message-ID: <20111102194507.GA14429@infradead.org> (raw)
In-Reply-To: <1320256339.3145.30.camel@doink>
We should validate that the value isn't negative in xfs_iformat_*,
although we currently don't do that. It already verified that it
fits into the XFS_DFORK_DSIZE, which should take care of fitting
into 32-bits. Adding another explicit check probably won't hurt,
given that XFS_DFORK_DSIZE is calculated dynamically based on the
fork offset.
