Subject: [PATCH 3/9] xfsprogs: fix missing error check in xfs_rtfree_range in libxfs
Date: Thu, 14 Jan 2010 21:09:06 +1100 [thread overview]
Message-ID: <1263463752-5052-4-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1263463752-5052-1-git-send-email-david@fromorbit.com>
When xfs_rtfind_forw() returns an error, the block is returned
uninitialised. xfs_rtfree_range() is not checking the error return,
so could be using an uninitialised block number for modifying bitmap
summary info.
