07f0846feb Major nit: i've confused link0 and link1 in my brain and/or in either
the man page or the source file.  Fix this.

Minor problem: don't choke with ENETDOWN early.  As long as our output
queue has space, put the IP packets there even if IPCP ain't up yet.
We will eventually be able delivering them once the PPP state machine
came up.

00081cc989 Major overhaul of the SyncPPP layer. Basically, this comprises now a
full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols.  I needed
this to provide PPP support for the BISDN project (right now).

Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer.  This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events).  Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles.  Please report if i broke
something in the existing drivers.

For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.

db99d43f6f Make sppp's logging human-readable. Also, use log(9), as opposed to
printf(9), so the log output doesn't clutter the console.

While i was at it, KNFified some function definitions.  This file was
very inconsistent in this respect.

b1c9d77e44 Use the MAC address of an interface for the host part of an IPX address
and not the MAC address of the first interface for every IPX address.
This is more inline with the way others like Novell do it.

a29f300e80 The long-awaited mega-massive-network-code- cleanup. Part I.
This commit includes the following changes:
1) Old-style (pr_usrreq()) protocols are no longer supported, the compatibility
glue for them is deleted, and the kernel will panic on boot if any are compiled
in.

2) Certain protocol entry points are modified to take a process structure,
so they they can easily tell whether or not it is possible to sleep, and
also to access credentials.

3) SS_PRIV is no more, and with it goes the SO_PRIVSTATE setsockopt()
call.  Protocols should use the process pointer they are now passed.

4) The PF_LOCAL and PF_ROUTE families have been updated to use the new
style, as has the `raw' skeleton family.

5) PF_LOCAL sockets now obey the process's umask when creating a socket
in the filesystem.

As a result, LINT is now broken.  I'm hoping that some enterprising hacker
with a bit more time will either make the broken bits work (should be
easy for netipx) or dike them out.

This is a patch to sys/net/if.c. What it does is patch the algorithm
for finding an IP address on an interface which most closely matches
a given IP address. The problem with it is when no address matches,
and you have to just pick one at random. Then the code ends up picking
the last IP address in the list. This patch changes things so it
picks up the first address instead.
Usually the first address is more useful as the later ones are aliases.

bbd17bf8e1 Add better support for retrieving management information from network
interfaces.  This creates two new tables in the net.link.generic branch
of the MIB; one contains (essentially) `ifdata' structures, and the other
contains a blob provided by the interface (and presumably used to
implement link-layer-specific MIB variables).  A number of things
have been moved around in the `ifnet' and `ifdata' structures, so
NEW VERSIONS OF ifconfig(8) AND routed(8) ARE REQUIRED.  (A simple
recompile is all that's necessary.)

I have a sample program which uses this interface for those interested
in making use of it.

commit renames pr_usrreq to pr_ousrreq so that old code which depended on it
would break in an obvious manner.  This commit also implements the new
interface for TCP, although the old function is left as an example
(#ifdef'ed out).  This commit ALSO fixes a longstanding bug in the
TCP timer processing (introduced by davidg on 1995/04/12) which caused
timer processing on a TCB to always stop after a single timer had
expired (because it misinterpreted the return value from tcp_usrreq()
to indicate that the TCB had been deleted).  Finally, some code
related to polling has been deleted from if.c because it is not
relevant t -current and doesn't look at all like my current code.

1db1fffa03 Disallow host routes that point to themselves. These routes serve no
purpose, other than to get in the way of the ARP table and cause
"can't allocate llinfo" errors.

This change may cause gated or routed to start complaining when adding
such routes.  If so, these programs will need to be fixed to not try
to add these routes.

9f9b3dc4ae Add three new route flags to help determine what sort of address
the destination represents.  For IP:

- Iff it is a host route, RTF_LOCAL and RTF_BROADCAST indicate local
  (belongs to this host) and broadcast addresses, respectively.

- For all routes, RTF_MULTICAST is set if the destination is multicast.

The RTF_BROADCAST flag is used by ip_output() to eliminate a call to
in_broadcast() in a common case; this gives about 1% in our packet-generation
experiments.  All three flags might be used (although they aren't now)
to determine whether a packet can be forwarded; a given host route can
represent a forwardable address if:

	(rt->rt_flags & (RTF_HOST | RTF_LOCAL | RTF_BROADCAST | RTF_MULTICAST))
	== RTF_HOST

Obviously, one still has to do all the work if a host route is not present,
but this code allows one to cache the results of such a lookup if rtalloc1()
is called without masking RTF_PRCLONING.

f7163ba751 Make user-level PPP on-demand with dynamic IP actually work.
Story so fr:
1) PPP on-demand with static IP works.
2) PPP on-demand with dynamic IP says "Host is down" on any IP request
The problem is that tun driver check its READY state by *first* ifconfig address.
i.e.:
set ifaddr <addr> <addr2>
works (static IP) and
set ifaddr 0 <addr2>
not works (dynamic IP) because first address is equal 0.
Since tun is always POINTOPOINT interface, dst address is more meaningfull.
I change checking to second (dst) address in READY test.
PPP on-demand finally works.

(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

rather than (cdevsw)

3ba6426d14 Change signature of rt->rt_output() so that it is compatible with
ifp->if_output() functions.  This way, initial implementations of
rt_output functionality can just lazily use if_output until customized
versions are written.

aca1a47cb4 When adding a route fails because there is already a route with the same
(mask,value) in the tree, don't immediately return EEXIST.  Instead, check
to see if the pre-existing route was generated by protcol-cloning.  If so,
then it is OK to simply blow away the old route and re-attempt the insertion.
If not, then fall back to the same error code as before.

9cdeffd562 Don't wait for output to drain in pppclose(). Discard output immediately
for the same reasons as in slclose().

Free the cblock in the canonical queue in pppclose().  This is a no-op in
the usual cases where the tty is being closed or the line discipline is
being switched back to the standard discipline, but it saves a cblock if
the line discipline is being switched to one that doesn't use the canonical
queue.

Add prototypes.  I use `extern' in prototypes for functions with bogus
linkage.  This should be fixed someday.

Continue cleaning up new init stuff yet again.

6b435e575c Call output process in slstart() whether or not there is any output. As
in pppstart(), the output process may be overloaded to handle hardware
flow control and hardware output completions.

Don't wait for output to drain in slclose().  Discard output immediately.
New output is not prevented while processes are waiting for output to
drain (this is a bug), so the wait was sometimes forever.  Infinite
waits are also possible when CCTS_OFLOW is enabled and CTS is down.
Infinite waits were also caused by the above bug in slstart().

Start changing new init stuff yet again: rename unused arg `dummy'.

2b14f991e6 Reviewed by: julian with quick glances by bruce and others
Submitted by:	terry (terry lambert)
This is  a composite of 3 patch sets submitted by terry.
they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..

NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..

certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)

The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the
'files' file.

9fa18570a2 Obtained from: partly from ancient patches of mine via 1.1.5
Introduce TS_CONNECTED and TS_ZOMBIE states.  TS_CONNECTED is set
while a connection is established.  It is set while (TS_CARR_ON or
CLOCAL is set) and TS_ZOMBIE is clear.  TS_ZOMBIE is set for on to
off transitions of TS_CARR_ON that occur when CLOCAL is clear and
is cleared for off to on transitions of CLOCAL.  I/o can only occur
while TS_CONNECTED is set.  TS_ZOMBIE prevents further i/o.

Split the input-event sleep address TSA_CARR_ON(tp) into TSA_CARR_ON(tp)
and TSA_HUP_OR_INPUT(tp).  The former address is now used only for
off to on carrier transitions and equivalent CLOCAL transitions.
The latter is used for all input events, all carrier transitions
and certain CLOCAL transitions.  There are some harmless extra
wakeups for rare connection- related events.  Previously there were
too many extra wakeups for non-rare input events.

Drivers now call l_modem() instead of setting TS_CARR_ON directly
to handle even the initial off to on transition of carrier.  They
should always have done this.  l_modem() now handles TS_CONNECTED
and TS_ZOMBIE as well as TS_CARR_ON.

gnu/isdn/iitty.c:
Set TS_CONNECTED for first open ourself to go with bogusly setting
CLOCAL.

i386/isa/syscons.c, i386/isa/pcvt/pcvt_drv.c:
We fake carrier, so don't also fake CLOCAL.

kern/tty.c:
Testing TS_CONNECTED instead of TS_CARR_ON fixes TIOCCONS forgetting to
test CLOCAL.  TS_ISOPEN was tested instead, but that broke when we disabled
the clearing of TS_ISOPEN for certain transitions of CLOCAL.

Testing TS_CONNECTED fixes ttyselect() returning false success for output
to devices in state !TS_CARR_ON && !CLOCAL.

Optimize the other selwakeup() call (this is not related to the other
changes).

kern/tty_pty.c:
ptcopen() can be declared in traditional C now that dev_t isn't short.

f0448ae4a2 Fix panic("ifpromisc failed") when shutting down a bpf tap when the attached
interface is no longer IFF_UP.
The test for IFF_UP in ifpromisc is only useful while enabling IFF_PROMISC
and the higher levels of the bpf code do not allow for the possibility of
failure while shutting down.  This is a trivial change.
Also, fixes PR#522.

267513a942 Obtained from: partly from ancient patches by ache and me via 1.1.5
Remove nullmodem().

It may be useful to have a null modem routine, but nullmodem()
wasn't one.  nullmodem() was identical to ttymodem() except it
didn't implement MDMBUF (carrier) flow control, didn't do any
wakeups for off to on carrier transitions, and didn't flush the
i/o queues for on to off carrier transitions (flushing has the side
effect of waking up readers and writers) although it did generate
SIGHUPs.  The wakeups must normally be done even if nullmodem() is
null in case something is sleeping waiting for a carrier transition.
In any case, the wakeups should be harmless.  They may cause bogus
results for select(), but select() is already bogus for nonstandard
line disciplines.

1394aff0cd Revision 1.21 of if_sl.c broke the traditional behaviour that
assigning an address to an interface automatically marks this
interface IFF_UP.  The fix corrects this (and closes PR sys/577).
This is consistent with the way ethernet interfaces are being handled.
