[PATCH 0/2] Fix a couple issues in moddep parsing

The first patch fixes an OOB read bug and the second outputs a less confusing
error to the user when the moddep.lst line is too long. Really it would be
better to support lines of unlimited length, but I'm not motivated to add that.
The condition under which these issues are triggered should never really happen
because no module (currently) has enough dependencies to generate such long
lines in moddep.lst. I was triggering this under some odd conditions where
the all_video module dependency line contained all grub modules. So I think
having a max length for moddep.lst lines is reasonable at this point.


Glenn Washburn (2):
  util/resolve.c: Do not read past the end of the array in read_dep_list
  util/resolve.c: Bail with error if moddep lst file line is too long
