thorpej bb1175954d Use <net/dlt.h> 2000-12-12 18:03:25 +00:00
thorpej c5293456da Adapt to bpfattach() changes, and further centralize the bpfattach()
and bpfdetach() calls into link-type subroutines where possible.
2000-12-12 18:00:22 +00:00
thorpej bfaf37d464 Use <net/dlt.h> to get the DLT_* constants. Also change bpfattach()
and bpf_change_type() to take just a pointer to the ifnet, rather than
a pointer to the ifnet and a pointer to a member of the ifnet (the bpf
pointer).

We'll let this ride on the Dec 12 1.5N version bump.
2000-12-12 17:55:21 +00:00
thorpej 00052cdc53 Put the BPF DLT_* constants into their own header file so that things
that reference them don't have to slurp in all of the BPF headers.

Define a new generic RAWAF type that is like DLT_RAW, but isn't specific
to IP (the macro takes an AF_* constant as an argument to generate the
actual type).

itojun 5eae50d991 update icmp6 too big validation. the change is necessary since pmtud is
mandatory for IPv6 (so we can't just validate by using connected pcb - we need
to allow traffic from unconnected pcb to do pmtud).
- if the traffic is validated by xx_ctlinput, allow up to "hiwat" pmtud
  route entries.
- if the traffic was not validated by xx_ctlinput, allow up to "lowat" pmtud
  route entries (there's upper limit, so bad guys cannot blow up our routing
  table).

onoe 2819c7b688 Use DMA from mbuf instead of copy in transmit.
Still use memcpy in receiving because we must use buffer fill mode
	and many packets may share single receive buffer.

XXX: Workaround(?) for CXD3222: it fails to DMA for selfid packet according
to code placement. I'm not sure about the reason (cache? timing? bug?).

Fixed the bug: transmitter sometimes stop and OACTIVE bit of if_fw
never be cleared.
Fixed the bug: freeing free buffer.

Enable ieee1394_drain and ieee1394_watchdog for loss of fragment.

bouyer 6e08061c2a Supports hardware 802.1q VLAN tagging, per discussion on tech-net. The tag is
stored in a m_aux mbuf defined by AF_LINK, ETHERTYPE_VLAN.

bouyer 0d0fd7718e Per discussion with Jason, change flags filter to
(IFF_UP | IFF_BROADCAST | IFF_RUNNING | IFF_ALLMULTI | IFF_SIMPLEX)
Also, put the ifp->if_opackets++ at the rigth place so that the counter is
incremented even when the parent is OACTIVE.
Fix a bug in vlan_input where the ethernet src and dst addrs would not be
correct because we only memmove() only ifv->ifv_encaplen instead of
sizeof(struct ether_header).

loose.

thorpej 65fd25ea82 Restructure the PFIL_HOOKS mechanism a bit:
- All packets are passed to PFIL_HOOKS as they come off the wire, i.e.
  fields in protocol headers in network order, etc.
- Allow for multiple hooks to be registered, using a "key" and a "dlt".
  The "dlt" is a BPF data link type, indicating what type of header is
  present.
- INET and INET6 register with key == AF_INET or AF_INET6, and
  dlt == DLT_RAW.
- PFIL_HOOKS now take an argument for the filter hook, and mbuf **,
  an ifnet *, and a direction (PFIL_IN or PFIL_OUT), thus making them
  less IP (really, IP Filter) centric.

Maintain compatibility with IP Filter by adding wrapper functions for
IP Filter.

2000-10-03 23:50:52 +00:00
thorpej 96375e93ea Improve the VLAN support, in particular, handling of MTU:
- Add a macro to compute the max frame length based on Ethertype
  and presence of FCS, and use it to validate the packet size
  in ether_input().
- Add capabilites to struct ethercom, and allow hardware drivers
  to specify that they can handle the larger hardware MTU that
  VLANs require in order to strictly conform to 802.1Q.
- Make ether_ifdetach() clear out the link address and free all of
  the Ethernet multicast structures.

Also, rearrange the VLAN driver itself in preparation to supporting
other hardware types, including FDDI (which has 802.1Q VLAN capability).

thorpej 8dc841aa19 Change the behavior of ifpromisc() slightly. If interface is not IFF_UP,
attempting to enable promisc would result in ENETDOWN.  Change this to
allow the interface to always be placed in promiscuous mode, regardless
of IFF_UP.  When the interface does come up, the IFF_PROMISC flag will
be consulted, and this matches the behavior that disabling promiscuous
mode has.

The length field is necessary because IEEE 802.11 spec doesn't prohibit
even '\0' for SSID.
Though the name and the value of SIOC... macro is unchanged, this change
breaks binary compatibility.  The only affected userland program on the
tree is ifconfig(8).

since there are no releases for this ioctls yet.

thorpej 920e0d4a44 Don't allow IFF_PROMISC to be changed directly by userspace. It
interferes with the reference counting done by ifpromisc(), and is
essentially impossible to get the semantics correct if we allow this

No programs should really be affected by this; IFF_PROMISC is basically
useless without bpf, anyway, and bpf still provides a way to set
promiscuous mode on an interface (which uses ifpromisc()).

mycroft fbb147f69b Check the multicast bit in the header mbuf while interrupts are still blocked.
Otherwise we can run off into space if the packet was sent immediately and the
mbuf freed.

itojun 92e64a4a0d sync with almost-latest KAME IPsec. full changelog would be too big
to mention here.  notable changes are like below.

kernel:
- make PF_KEY kernel interface more robust against broken input stream.
  it includes complete internal structure change in sys/netkey/key.c.
- remove non-RFC compliant change in PF_KEY API, in particular,
  in struct sadb_msg.  we cannot just change these standard structs.
  sadb_x_sa2 is introduced instead.
- remove prototypes for pfkey_xx functions from /usr/include/net/pfkeyv2.h.
  these functions are not supplied in /usr/lib.

setkey(8):
- get/delete does not require "-m mode" (ignored with warning, if you
  specify it)
- spddelete takes direction specification

  Fix a panic resulting from an obvious null pointer deref.
  Apparently some other panics still exist in this driver, but with
  this fix, it was at least possible to run the Nokia card at SANE 2000.

itojun 4631e5d720 improve duplicated 'gifconfig" check (fatal typo was there). sync with kame. 2000-05-17 01:14:04 +00:00
itojun 3c67584219 propose better IPv6 ifid alternative to the peer, when ifid collides
during IPv6CP negotiation.  it is very rare to see collision.
2000-05-16 05:45:27 +00:00

itojun 3df6dbc4c7 add packed attribute to struct ifreq. this should avoid unaligned access
while parsing SIOCGIFCONF, on alignment-picky archs.

thorpej 5e6bec6a7e - Fix a bug in the double-loop version of ether_crc32_le() -- we're not't
supposed to bubble carry through.
- Disable the double-loop version of ether_crc32_le() and add a
  table-driven version of ether_crc32_le() -- the table-driven
  version is faster.

ragge 8a9c114515 Change rt_refcnt from short to int, to allow more than 32k routes thru
one interface without unexpected side effects.
2000-05-04 17:33:03 +00:00
itojun aee9bb5b5f IPv6CP support. if IPv6 link-local address is configured to the interface,
the interface tries to negotiate ifid with the other end by using IPv6CP.

other changes:
- do not share ppp sequence number across protocols.
- if LCP proto-rej is received, drop the protocol mentioned by the message.
  this is to be friendly with non-IPv6 peer (if the peer complains due to
  lack of IPv6CP, drop IPv6CP).  this basically implements "RXJ+" state
  transition in the RFC.
- cleanup debugging message.  always print blank just before message.

CAVEAT:
- if the peer uses the same MAC address as our side (pretty unlikely)
  the code may go into req-rej loop.
- even though we negotiate ifid, we don't configure destination address
  onto the interface.  it is not really necessary to do so (IMHO).
- I've tested this code on a NetBSD 1.4.2 node, which was with fair amount
  of modifications.  not sure if the committed code does it right... (please
  test and send reports)

bouyer 4e9473a1e7 ifa_ifwithnet(): for the netatalk case, don't blindly return the first match

itojun eaeb53372e update comment (analysis on 04 draft) 2000-04-21 02:40:53 +00:00
itojun d300ce3942 add net/if_stf.h and netinet/ip_encap.h (almost noone will include them though) 2000-04-19 06:39:15 +00:00
itojun 3909133548 introduce sys/netinet/ip_encap.c, to dispatch inbound packets
to protocol handlers, based on src/dst (for ip proto #4/41).
see comment in ip_encap.c for details of the problem we have.
there are too many protocol specs for ip proto #4/41.
backward compatibility with MROUTING case is now provided in ip_encap.c.

fix ipip to work with gif (using ip_encap.c).  sorry for breakage.

gif now uses ip_encap.c.

introduce stf pseudo interface (implements 6to4, another IPv6-over-IPv4 code
with ip proto #41).
2000-04-19 06:30:51 +00:00
itojun 5e5941eda1 remove extra memory region kept by "struct pfil_head pfil_head_t;".
it seems totally, unnecessary, or seems to be typo for typedef.

itojun c24f5b5068 add more IPv6 cases. not tested.
TODO: IPv6CP support.  currently IPv6 packet will be generated right
after link up (spec violation)
2000-04-12 10:51:15 +00:00
itojun ecb5f2e56a revisit in6_ifattach().
- be persistent on initializing interfaces, even if there's manually-
  assigned linklocal, multicast/whatever initialization is necessary.
- do not cache mac addr in the kernel.  grab mac addr from existing cards
  (this is important when you swap ethernet cards back and forth)
now ppp6 works just fine!

call in6_ifattach() on ATM PVC interface to assign link-local, using
hardware MAC address as seed.

(the change is in sync with kame tree).

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
