thorpej 57aae5ce02 On second thought, only set a default baudrate for "ethernet" if one
isn't set already.
2000-03-06 21:03:46 +00:00
thorpej b99cf790df - Initialize ifp->if_baudrate to a sensible value when the interface is
attached.
- Add ether_crc32_be() and ether_crc_le(), common functions for computing
  the Ethernet CRC on arbitrary length buffers.  Nothing uses them yet,
  and these should be double-checked and probably re-implemented as
  table-driven functions.

thorpej d844a3ac41 First-draft if_detach() implementation, originally from Bill Studnemund,
although this version has been changed somewhat:
- reference counting on ifaddrs isn't as complete as Bill's original
  work was.  This is hard to get right, and we should attack one
  protocol at a time.
- This doesn't do reference counting or dynamic allocation of ifnets yet.
- This version introduces a new PRU -- PRU_PURGEADDR, which is used to
  purge an ifaddr from a protocol.  The old method Bill used didn't work
  on all protocols, and it only worked on some because it was Very Lucky.

This mostly works ... i.e. works for my USB Ethernet, except for a dangling
ifaddr reference left by the IPv6 code; have not yet tracked this down.

itojun ea861f0183 sync IPv6 part with latest KAME tree. IPsec part is left unmodified
due to massive changes in KAME side.
- IPv6 output goes through nd6_output
- faith can capture IPv4 packets as well - you can run IPv4-to-IPv6 translator
  using heavily modified DNS servers
- per-interface statistics (required for IPv6 MIB)
- interface autoconfig is revisited
- udp input handling has a big change for mapped address support.
- introduce in4_cksum() for non-overwriting checksumming
- introduce m_pulldown()
- neighbor discovery cleanups/improvements
- netinet/in.h strictly conforms to RFC2553 (no extra defs visible to userland)
- IFA_STATS is fixed a bit (not tested)
- and more more more.

TODO:
- cleanup os-independency #ifdef
- avoid rcvif dual use (for IPsec) to help ifdetach

(sorry for jumbo commit, I can't separate this any more...)

itojun 6b9bfc0691 - Call in{,6}_pcbdetach if ipsec initialization is failed during PRU_ATTACH.
This situation happens on severe memory shortage.  We may need more
  improvements here and there.
- Grab IEEE802 address from IFT_ETHER card, even if the card is
  inserted after bootup time.  Is there any other card that can be
  inserted afterwards?  pcmcia fddi card? :-P
- RFC2373 u bit handling suggests that we SHOULD NOT copy interface id from
  ethernet card to pseudo interface, when ethernet card has IEEE802/EUI64
  with u bit != 0 (this means that IEEE802/EUI64 is not universally unique).
  Do not use such address as, for example, interface id for gif interface.
  (I have such an ethernet card myself)
  This may change interface id for your gif interface.  be careful upgrading
  rc files.

(sync with recent KAME)

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.

bouyer cc6eca7553 mbuf should be allocated with M_DONTWAIT in ether_output(). This caused panics
when routing atalk.

thorpej f98d358a1f Rework layer 2 protocol input routines. Instead of calling e.g. ether_input()
directly, call the function pointer (*if_input)(ifp, m).  The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary.  Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.

kim cd7e3136ad Use ETHERTYPE_ATALK instead of ETHERTYPE_AT. The former seems more common.
Our other constants also use "ATALK".

Added many new ETHERTYPE constants to sys/net/ethertypes.h, including the
ones from libpcap and tcpdump "ethertype.h" files.

thorpej 5e5904eb39 In ether_output(), if the socket address family is pseudo_AF_HDRCMPLT,
use the Ethernet source address speficied in the sockaddr rather than
the interface's Ethernet address, and then fall through to the AF_UNSPEC
case.  From Greg Smith <greg@nas.nasa.gov>.

matt d4d709f7d0 Add support for "fast" forwarding. Add hooks in if_ethersubr.c and
if_fddisubr.c to fastpath IP forwarding.  If ip_forward successfully
forwards a packet, it will create a cache (ipflow) entry.  ether_input
and fddi_input will first call ipflow_fastforward with the received
packet and if the packet passes enough tests, it will be forwarded (the
ttl is decremented and the cksum is adjusted incrementally).

is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

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.
