hannken 2a59794a70 Fix typo introduced in rev. 1.55.
It caused IP6 packets to be sent as AF_UNSPEC instead of AF_INET6.

itojun 118d2b1d4f IPv6 kernel code, based on KAME/NetBSD 1.4, SNAP kit 19990628.
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.

- sys/kern: do not assume single mbuf, accept chained mbuf on passing
  data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
  package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
  file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen

In my understanding no code here is subject to export control so it
should be safe.

tron 81897066b9 Fix compilation problem caused by recent changes to filtering code. 1999-05-14 21:33:41 +00:00
thorpej 7e3a0bf0c5 Decouple inbound and outbound filters. Now instead of using "active-filter"
and "pass-filter" and "inbound" and "outbound" qualifiers in the filter
expression, use new "active-filter-in", "active-filter-out", "pass-filter-in",
and "pass-filter-out" without these qualifiers.

This is necessary due to the horrible, awful way "inbound" and "outbound"
were specified for the filter programs when a packet was passed through them.
Basically, the "address" byte in the serial PPP header was overwritten with
a value to indicate the direction.  However, the "address" byte doesn't even
exist on PPP headers for all other PPP encaps!  So, this old method worked
only for serial encaps, and corrupted packets for all others (PPPoE, ATM, etc.)

thorpej 4c89a367d5 * Start out with a data link type of DLT_NULL. When we change an interface
to serial encap, change its data link type to DLT_PPP_SERIAL.
* Work around some serious bogosity in the filtering code which utterly
breaks proper functioning of BPF.  The PPP code and pppd(8) WILL be changed
to fix this.

thorpej d70bb64a38 Use M_LINK{0,1} for our own mbuf flags, rather than arbitrarily picking
2 bits.

sommerfe 3858a1179a Only run pppasyncstart (sc->sc_start) from the netisr handler.
This allows pppoutput to be called from splimp (e.g., when ipflow is
in use.) without requiring pppasyncstart to run at splimp.
This is believed to fix PR5624.

thorpej 4edabe2501 Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.

dependent on the PPP_BSDCOMP and PPP_DEFLATE kernel configuration
options, respectively.

paulus 6654fd558b Added packet filtering, support for "PPP Deflate" packet compression,
trivial multicast support, and support for xon/xoff output flow
control to the PPP subsystem.  Fixed several bugs, including making
the accumulation and resetting of statistics more consistent.  State
for the VJ compressor is now dynamically allocated.

paulus 7f06ab8b0b Latest version of PPP stuff, with packet compression and other
improvements.  The PPP kernel code is now split into if_ppp.c,
containing generic PPP support, and ppp_tty.c, which specifically
supports PPP on async tty devices (as a line discipline).  This is
so that other devices can be supported without making them look
like ttys.

paulus ce6d680c66 The ppp interface now retries the mbuf allocation when it receives
a character and it doesn't already have enough space allocated.
It still needs cluster mbufs to be able to decompress VJ-compressed
packets.  It drops packets if it can't allocate mbufs rather than
taking the interface down.
