This change will allow a PPP host enabled with the "-alias" option to
run mrouted. This does not intend to forward the IGMP nor tunneled packets
to another host on the far side if the tun0 interface.
sl_uncompress_tcp() and drop packets with
slot numbers that are out of range.
o Drop packets that want to use a slot that still
has an IP header length of 0 (ie, the requested
slot number is bogus again).
Without this code, if the other side mis-behaves (and
sends us garbage slot numbers), we happily ``adjust''
a memset(..., '\0', ...) TCP/IP header and promptly
cr*p all over the stack before returning.... quickly
followed by a SIGBUS.

There's still a link lockup after this happens, but my
bets are on the other side (who has already started sending
rubbish) being to blame.
- connector selection values (should fix aui/bnc),
- non-shifting version of crc calculation using a table,
- interrupt mask adjustments,
- add some brackets where a #ifdef could break an if(),
- don't reset the card unless it's up.
that had an inode that has not yet been written to disk, when the inode of the
new file is also not yet written to disk, and your old directory entry is not
yet on disk but you need to remove it and the new name exists in memory
but has been deleted but the transaction to write the deleted name to disk
exists and has not yet been cancelled by the request to delete the non
existant name. I don't know how kirk could have missed such a glaring
problem for so long. :-) Especially since the inconsitency survived on
the disk for a whole 4 second on average before being fixed by other code.
This was not a crashing bug but just led to filesystem inconsitencies
if you crashed.

for all datalinks in a bundle. Ppp now deals correctly
with link types that are changed while open
o When changing the type of the last AUTO link, only clear
the interface if we're not in PHASE_NETWORK. This allows
us to switch to -ddial mode while we have a connection
without suddenly unexpectedly throttling ourselves by
clearing the interface configuration.

Remove lots'o'hacks.
looutput is now static.
Other callers who want to use loopback to allow shortcutting
should call the special entrypoint for this, if_simloop(), which is
specifically designed for this purpose. Using looutput for this purpose
was problematic, particularly with bpf and trying to keep track
of whether one should be using the charateristics of the loopback interface
or the interface (e.g. if_ethersubr.c) that was requesting the loopback.
There was a whole class of errors due to this mis-use each of which had
hacks to cover them up.
Consists largly of hack removal :-)
propagates a bug (that there is no poll wrapper in libc_r), but it
prevents GNU configure scripts from trying to use it in preference
to select. libc_r really needs to change it's wait interface to use
poll instead of select because poll is more a superset of select that
the other way around.
This should allow the Roxen web server to work out-of-the-box. It's
configuration intercae is kinda neat. The code isn't. Shiver. 8-)
