much space we wanted.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$ 
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

8df9b2ce24 Fix my yesterday's brain-o: don't account for the kilobytes twice. 1996-10-14 22:56:01 +00:00
Joerg Wunsch
927e7941a3 Yikes! Originally, i intended to apply the patch from PR # 1322, 
but Bill has beaten me on this. ;-)

However, he missed the part to compute the kernelsize in kilobytes,
so the minfree consideration was now overcautious.  (I've also
changed the return type of dump_size() to void since int was useless.)

Being here, the fact that `vmcore' was written world-readable was just
a plain security hole: everybody who was able to crash a kernel could
later read any confidential information out of it at his will.  Create
it with umask 077 instead.

4731e263af Make the savecore command work like the man page says: 
- make minfree work by getting the dump size before checking to see
  if the dump will fit on the filesystem
- also fail to dump if no minfree is specified but there are not enough
  free blocks.

Fix a typo in the man page.

Fixes PR bin/1322

50e2fb8055 Remove a bogus fclose. Normally the "w" stream for /var/crash/bounds was 
fclosed twice and this didn't seem to cause any problems, but when
/var/crash was on an an unwritable nfs-mounted partition, fclose(NULL)
caused a core dump.

08e9e0741b The -N option takes one argument, hence the getopt control string 
needs to have a colon for it.  Looks like nobody has tested this
so far.

4be4929c2b Get rid of _PATH_UNIX completely; use getbootfile(3) instead. 
DANGER WILL ROBINSON!
_PATH_UNIX is currently defined as the literal string "don't use this".
I am of two minds about this myself, but wanted to get something into the
tree as quickly as possible.
