34fe62c776 Fixed some style bugs in the removal of __P(()). The main ones were
not removing tabs before "__P((", and not outdenting continuation lines
to preserve non-KNF lining up of code with parentheses.  Switch to KNF
formatting and/or rewrap the whole prototype in some cases.

e38eb7fbe4 Fix a bug introduced in 1.11 (and also MFCd to stable AND the security branch)
that causes a machine to panic when the kernel PPP / DEFLATE code is used.
1.11 moved a ZFREE to a point after the structural members were clobbered
by stores into a union'd structure.

This commit fixes the bug and adds a big whopping comment to make sure
the code isn't 'cleaned up' again :-)

Ian Dowse came up with the same patch independantly 68 seconds before I
did, talk about Karma!

I would also like to thank Eugene Grosbein for marathon work in tracking the
problem down by udpating his -stable based on date over and over again
to close in on the commit that caused his crashes.

42786f6c03 Add hooks for very basic IPFilter support in bridging. Set,
# sysctl net.link.ether.bdg_ipf=1

To enable. Just like ipfw(8) bridging, only input packets are filtered
in the bridge. Filtering works just like in the IP layer, ipf(8)
first, then ipfw(8). And just like in the IP layer, both are
independent, one need not be run to use the other. (Note: This will
not work in, but doesn't break, the bridge.ko module. The ipl.ko
module would need to be fixed before that is worth worrying about.)

f591779bb5 Lock struct pgrp, session and sigio.
New locks are:

- pgrpsess_lock which locks the whole pgrps and sessions,
- pg_mtx which protects the pgrp members, and
- s_mtx which protects the session members.

Please refer to sys/proc.h for the coverage of these locks.

Changes on the pgrp/session interface:

- pgfind() needs the pgrpsess_lock held.

- The caller of enterpgrp() is responsible to allocate a new pgrp and
  session.

- Call enterthispgrp() in order to enter an existing pgrp.

- pgsignal() requires a pgrp lock held.

b2c08f43d0 When the local link address is changed, send out gratuitous ARPs
to notify other nodes about the address change. Otherwise, they
might try and keep using the old address until their arp table
entry times out and the address is refreshed.

Maybe this ought to be done for INET6 addresses as well but i have
no idea how to do it. It should be pretty straightforward though.

o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
  POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
  and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
  complexities associated with having MD (asm and inline) versions, and
  having to prevent exposure of these functions in other headers that
  happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
  third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.

e88516c29b Lots of improvement to the bridging code.
In order of importance:

 + each cluster now uses private data structures (filtering and
   local address tables) so you can treat them as fully independent
   switches. This part of the work was supported by:
        Cisco Systems, Inc. - NSITE lab, RTP, NC.

 + cleaned up the handling of configuration, so the system will behave
   much better when real or pseudo devices are dynamically attached
   or detached. It should also not panic anymore on systems with large
   number of devices, closing a few existings PRs on the topic.

 + while at it, add support for VLAN. This means that a FreeBSD box
   can now work as a real VLAN switch, with trunk interfaces etc.
   As an example:
        ifconfig vlan0 vlan 3 vlandev dc0
        ifconfig vlan1 vlan 4 vlandev dc0
        net.link.ether.bridge_cfg="vlan0:3,dc1:3,vlan1:4,dc1:4"
   uses dc0 as a trunk interface, and dc1 and dc3 as ports on vlans 3 and 4
   You get the idea...
   NOTA BENE: by default bridge_cfg is initialised to "" so even if
   you enable bridging, no packets will be bridged until you set the
   list of interfaces on which you want this to happen.

 + large restructuring of the code, moving private vars and types from
   bridge.h to bridge.c.

 + added a lot of comments to the code to explain how to use it.

694ff26473 Prevent the kernel from generating an unaligned sysctl data buffer on
64-bit platforms.  The unaligned access is caused by struct ifa_msghdr
not being a multiple of 8-bytes in size.  If an interface has an odd
number of addresses, this causes the next interface to generate an
unaligned access in the user-level app walking the interfaces (ifconfig).

ee037f26bc Implement an option to administratively disable the negotiation of
IPv6 on an sppp interface.  In an IPv6-enabled kernel, every IPv6
interface automatically gets an IPv6 address assigned (and IPv6
multicast packets sent at initialization time).  For sppp links where
we know our remote peer wouldn't support IPv6 at all, there's no point
in attempting to negotiate IPV6CP (or to even dial out for an IPv6
packet at all for dial-on-demand interfaces).

I wish there were a more generic way to administratively disable IPv6
on an interface instead.  ume told me there isn't.

While i was at it, converted both, enable_vj and enable_ipv6 into flag
bits in struct sppp (enable_vj used to be an int of its own).
