edff69904f Quick fix for breakage of bounds checking in rev.1.12. Only one
of the additional checks in rev.1.12 was wrong.  The others are a
bit inconsistent and are probably unnecessarily pessimal.  Checking
for overflow of addition, if necessary at all, should be done in
bpf_validate().

64e41ba7c8 Increase the size of the route reference count from 15 bits to 31 bits.
This doesn't change the size or alignment of the structure on either i386
or Alpha, and thus should be binary-compatible (modulo problems with old
applications and routes with more than 2^15 references).

cce2eb6a97 Never return the root node itself from rn_match(); return NULL instead.
This caused a panic in rtfreee() called with a root node from the
routing socket code (when processing a RTM_GET message looking for
the default route while there is none).

Since no existing code seems to have any use getting the root node
from rn_match(), it seems cleaner never to return it rather than
check for this condition at the caller's.

413dd0ba39 Add a new interface ioctl, to return "aux status".
This is inteded for to allow ifconfig to print various unstructured
information from an interface.

The data is returned from the kernel in ASCII form, see the comment in
if.h for some technicalities.

Canonical cut&paste example to be found in if_tun.c

Initial use:
        Now tun* interfaces tell the PID of the process which opened them.

Future uses could be (volounteers welcome!):
        Have ppp/slip interfaces tell which tty they use.
        Make sync interfaces return their media state: red/yellow/blue
        alarm, timeslot assignment and so on.

cf4b937128 Introduce IFF_SMART bit.
This means that the driver will add/delete routes when it knows it is
up/down, rather than have the generic code belive it is up if configured.

This is probably most useful for serial lines, although many PHY chips
could probably tell us if we're connected to the cable/hub as well.

2447bec829 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

75c1354190 This Implements the mumbled about "Jail" feature.
This is a seriously beefed up chroot kind of thing.  The process
is jailed along the same lines as a chroot does it, but with
additional tough restrictions imposed on what the superuser can do.

For all I know, it is safe to hand over the root bit inside a
prison to the customer living in that prison, this is what
it was developed for in fact:  "real virtual servers".

Each prison has an ip number associated with it, which all IP
communications will be coerced to use and each prison has its own
hostname.

Needless to say, you need more RAM this way, but the advantage is
that each customer can run their own particular version of apache
and not stomp on the toes of their neighbors.

It generally does what one would expect, but setting up a jail
still takes a little knowledge.

A few notes:

   I have no scripts for setting up a jail, don't ask me for them.

   The IP number should be an alias on one of the interfaces.

   mount a /proc in each jail, it will make ps more useable.

   /proc/<pid>/status tells the hostname of the prison for
   jailed processes.

   Quotas are only sensible if you have a mountpoint per prison.

   There are no privisions for stopping resource-hogging.

   Some "#ifdef INET" and similar may be missing (send patches!)

If somebody wants to take it from here and develop it into
more of a "virtual machine" they should be most welcome!

Tools, comments, patches & documentation most welcome.

Have fun...

e306e8ea66 Temporary hack. The radix code shouldn't need this, it should be
able to expand the zeros, ones etc masks on the fly.  It seems a good
number of domains don't set the rn_maxkey variable anyway, and because
this is a domain itself, there is no guarantee we've been called after
a protocol that actually has set it (ie: inet), so start with a maxkey
of a relatively sane size as a base point until it can adapt on the fly.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

831d27a9f5 Installed the second patch attached to kern/7899 with some changes suggested
by bde, a few other tweaks to get the patch to apply cleanly again and
some improvements to the comments.

This change closes some fairly minor security holes associated with
F_SETOWN, fixes a few bugs, and removes some limitations that F_SETOWN
had on tty devices.  For more details, see the description on the PR.

Because this patch increases the size of the proc and pgrp structures,
it is necessary to re-install the includes and recompile libkvm,
the vinum lkm, fstat, gcore, gdb, ipfilter, ps, top, and w.

5158516f4e In an attempt to reduce the huge number of differences between the
FreeBSD repository version of this file and the isdn4bsd version,
adopt those changes from the i4b version that make this file
BSD-version independent.  I attempted to avoid uglifying this file too
much, thus deviated a little from the i4b version (and hope they will
adopt the changes, too).

The diffs mostly concentrate on:

. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
  unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in
  Net/OpenBSD (for loopback detection ad CHAP challenges -- i
  assume at least OpenBSD could also benefit from random(), but that's
  the way i've got this file)
. interface address list elements are named a little differently
  between FreeBSD and Net/OpenBSD

I attempted to segregate those compat fixes from other code fixes and
enhancements.

c7323482f4 One-liner: add a call to the underlying device driver's SIOCDELMULTI
ioctl() routine at the end of if_delmulti() so that interfaces with
hardware multicast filtering can update their filters in a timely
manner.

If the interface doesn't support hardware multicast filtering, then
reception of multicast frames is done using 'promiscious mode' or
'capture all multicast frames' mode and software filtering in the
kernel. In this case, it doesn't matter if if_delmulti() ever does
an SCIODELMULTI on the interface or not: if MULTICAST support is
enabled, then we join the 'all hosts' group when the interface is
configured, and remain in it until the interface is brought down.
Without hardware filtering, joining one group means joining all
groups, so it makes no difference if we call the SIOCDELMULTI
routine.

If the interface does support hardware multicast filtering, then
by not reprogramming the hardware filter in if_delmulti(), we have
to wait until somebody calls if_setmulti(), during which time the
interface is receiving frames for multicast groups in which we are
no longer interested.

code cleanup:
	- remove WMAYBE related code.  ENI WMAYBE DMA doen't work.
	- remove updating if_lastchange for every packet.
	- BPF related code is moved to midway.c as it should be.
	  (bpfwrite should work if atm_pseudohdr and LLC/SNAP are

	- BPF link type is changed to DLT_ATM_RFC1483.
	  BPF now understands only LLC/SNAP!! (because bpf can't
	  handle variable link header length.)
	  It is recommended to use LLC/SNAP instead of NULL

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.

NetBSD, ported to FreeBSD by Pierre Beyssac <pb@fasterix.freenix.org> and
minorly tweaked by me.
This is a standard part of FreeBSD, but must be enabled with:
"sysctl -w net.inet.ip.fastforwarding=1" ...and of course forwarding must
also be enabled. This should probably be modified to use the zone
allocator for speed and space efficiency. The current algorithm also
appears to lose if the number of active paths exceeds IPFLOW_MAX (256),
in which case it wastes lots of time trying to figure out which cache
entry to drop.

227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

1) in the CHAP_CHALLENGE case don't output the peer's name if it is not
what we expected (DEBUG) since it will be printed out in the course
of events anyway.
2) in the CHAP_SUCCESS case test whether the peer is required to
authenticate himself [(sp->lcp.opts & (1 << LCP_OPT_AUTH_PROTO))],
otherwise the state machine may never switch into the network state.
I saw this case against 2 different ISPs; they never bothered to
authenticate themselves to me.

In sppp_pap_input:
in the PAP_ACK case do the same as in 2) above for the same reason.

d7189ec67c Ooops, this should have made it into the same commit, but didn't.
Introduce the SIOC[SG]IFGENERIC hooks that can be used to pass an
arbritrary ioctl subcommand into an interface driver.  Surprisingly
enough, there was no provision for this already present (except of the
option of abusing SIOC[SG]IFMEDIA for this).

The idea is that an interface driver can establish ioctl subcommands
of its own that can't be meaningfully interpreted by the upper layer
interface ioctl function.  Something like this is required to
implement a clean solution of passing down things like CHAP secrets or
PPP options to the /sys/net/if_sppp* files.  (Yes, my CHAP is now
finally working with it, but i gotta update my kernel to the new
callout interface before being able to commit _that_.)

a353ca89cd Bruce mentioned to me that Paul Traina had noticed that the ppp_tty
interrupt mask hackery wasn't happening when being modloaded via the
if_ppp lkm.  It seems that the lkm system doesn't particularly like having
two sets of load/unload/etc routines. :-]  This really should be fixed
by having a seperate if_ppp and ppp_tty lkm, but that requires that ppp_tty
is loaded after if_ppp, and needs to be able to link with symbols in
if_ppp.  This gets messy, it is a better task for the in-kernel linker.
(if_ppp is generic, ppp_tty is a tty-specific bottom end for if_ppp, it's
 not _too_ hard to have another "provider" (such as a hdlc sync card)

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.

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.

528f627f00 Don't include <sys/ioctl.h> in the kernel. Stage 6: include
<sys/filio.h>, <sys/sockio.h> and <sys/ttycom.h> instead of
<sys/ioctl.h> in a couple of files.  This is still only 1/3
as spammish as <sys/ioctl.h> - 5 or 6 old tty ioctl headers
aren't needed.

2098241054 Don't include <sys/ioctl.h> in the kernel. Stage 4: include
<sys/ttycom.h> and sometimes <sys/filio.h> instead of <sys/ioctl.h>
in miscellaneous files.  Most of these files have nothing to do
with ttys but need to include <sys/ttycom.h> to get the definitions
of TIOC[SG]PGRP which are (ab)used to convert F[SG]ETOWN fcntls into
ioctls.

fce002fdef Don't include <sys/ioctl.h> in the kernel. Stage 1: don't include
it when it is not used.  In most cases, the reasons for including it
went away when the special ioctl headers became self-sufficient.
