CVS commit: [netbsd-2-0] src/sbin/savecore

[Thor Lancelot Simon <tls%netbsd.org@localhost>]

Module Name:    src
Committed By:   tls
Date:           Wed Jul 14 07:14:50 UTC 2004

Modified Files:
        src/sbin/savecore [netbsd-2-0]: savecore.c

Log Message:
Fix an integer overflow that prevented saving cores from machines with
more than 2GB of RAM.

"dumpsize" in the on-disk core header is in pages, but, unfortunately,
c.size in our kcore format is an unsigned 32-bit int, gross.

We sleaze it, using a 64-bit int internally here and handing it to
libkvm as a *signed* 32-bit int.  Won't always work, but shouldn't be
broken any worse than it is now, and sometimes work better.

We must fix the kcore format and libkvm.
