[LinuxBIOS] r480 - LinuxBIOSv3/util/lar

[svn at openbios.org]

Author: uwe

New Revision: 480

Modified:
   LinuxBIOSv3/util/lar/stream.c
Log:
The checksum creation in lar starts somewhere in the lar image,
and ends at the end of a temporary buffer, which doesn't look
right to me (and segfaults if between those two there's an unmapped
region, as happened here).
