This patch allows true interface routing to be controlled
from the command line..
you can now do:
route add default -interface ppp0
even if you have no clue what the address at the other end is..
this is part of a set of changes that allow true "unnumbered links"
such as netcom run between their sites..
In practice you should assign the address from one of your ethernet
interfaces to the local side of the P2P link so that IP doesn't
say that the packet comes from 255.255.255.255, but
there is no need whatsoever to assign an address of any kind
to the remote end of the link.. useful for frame relay links etc also.
Note, this is not really a security risk, because the buffer in question
is a static variable in the data segment and not on the stack, and hence
cannot subert the flow of execution in any way. About the worst case was
that if you pinged a long hostname, ping could coredump.

indicate that the mount information should be printed in fstab
format.
This is a neat way to create a new fstab file to use later when
one has modified the mount points or mount options or added or
removed mount some mount points. You just type
mount -p > /etc/fstab.new
and there is your new fstab file ready to be used though you
will of course have to add any necessary noauto flags manually.

Subject: Fix for annoying fsck bug
Date: Wed, 24 Jan 1996 13:33:29 -0700 (MST)
The following small diff fixes the annoying fsck bug that causes it to
need to be run twice to end up with correct reference counts for inodes
for directories that had subdirectories relocated into the lost+found
directory.
I found the need to rerun *extremely* annoying. This fix causes the
count to be correctly adjusted later in pass 4 by correctly stating
the parent reference count.
Note that the parent reference count is incremented when the directory
entry is made (for ".."), but is not really there in the case of a
directory that does not make an entry in its parent dir.
This can be tested by waiting for the inode sync after cd'ing from a
shell into a test fs. Then you "mkdir xxx yyy zzz", wait a second,
and hit the machine reset button.

want to do a "char foo[100];" and have malloc break down when someone
decides to add a few more paths to a variable that's far apart from
this code. :)
By the way, there is no malloc() off-by-one error for the '\0' at the
end of the string although I don't explicitly add 1 to the length.
The code allocates strlen(path element)+2 bytes for each path element,
and doesn't use the last two bytes (for the delimiting ", ").

lock" panic from happening.
This is a temporary fix. A kernel fix would be much much more ugly than
this, and still wouldn't be the "right" way to fix it. After some
of Terry's file system rework is installed, it will be possible to
properly fix this problem in a clean manner. Until then,
this change should prevent use from getting a problem report
on this every month or so (and I just noticed that someone in
one of the freebsd news groups was complaining about this problem, too).
spit out two error lines for a bogus filesystem type, e.g:
root@time-> mount -t foo /dev/sd0a /mnt
mount: exec /sbin/mount_foo for /mnt: No such file or directory
mount: exec /usr/sbin/mount_foo for /mnt: No such file or directory
But I would submit that if you're even going to scan multiple directories
for a mount_foo (which I actually think is somewhat bogus - if it's not
in /sbin, you're probably in big trouble anyway), you should emit an error
for each one. I got multiple complaints (in addition to the PR) that the
existing behavior was very confusing.

- getnetgrent.c: address some NIS compatibility problems. We really need
to use the netgroup.byuser and netgroup.byhost maps to speed up innetgr()
when using NIS. Also, change the NIS interaction in the following way:
If /etc/netgroup does not exist or is empty (or contains only the
NIS '+' token), we now use NIS exclusively. This lets us use the
'reverse netgroup' maps and is more or less the behavior of other
platforms.
If /etc/netgroup exists and contains local netgroup data (but no '+').
we use only lthe local stuff and ignore NIS.
If /etc/netgroup exists and contains both local data and the '+',
we use the local data nd the netgroup map as a single combined
database (which, unfortunately, can be slow when the netgroup
database is large). This is what we have been doing up until now.
Head off a potential NULL pointer dereference in the old innetgr()
matching code.
Also fix the way the NIS netgroup map is incorporated into things:
adding the '+' is supposed to make it seem as though the netgroup
database is 'inserted' wherever the '+' is placed. We didn't quite
do it that way before.
(The NetBSD people apparently use a real, honest-to-gosh, netgroup.db
database that works just like the password database. This is
actually a neat idea since netgroups is the sort of thing that
can really benefit from having multi-key search capability,
particularly since reverse lookups require more than a trivial
amount of processing. Should we do something like this too?)
- netgroup.5: document all this stuff.
- rcmd.c: some sleuthing with some test programs linked with my own
version of innetgr() has revealed that SunOS always passes the NIS
domain name to innetgr() in the 'domain' argument. We might as well
do the same (if YP is defined).
- ether_addr.c: also fix the NIS interaction so that placing the
'+' token in the /etc/ethers file makes it seem like the NIS
ethers data is 'inserted' at that point. (Chances are nobody will
notice the effect of this change, which is just te way I like it. :)
