Subject: [PATCH 0/8, v3] ensure symlinks are NUL-terminated
Date: Tue, 16 Dec 2008 15:51:52 +0000 [thread overview]
Message-ID: <1229442720-31056-1-git-send-email-duaneg@dghda.com> (raw)
These patches fix potential bugs associated with link target handling by
NUL-terminating names read from disk.
This is version 3 of these patches. It fixes the bug, pointed out by Al Viro
and Evgeniy Dushistov, that i_size was not being validated. In order to
facilitate this it introduces a helper function for terminating the link name,
as suggested by Al.
