thorpej cdcd4fad5e In if_qflush(), use IFQ_PURGE() rathen than an open-coded version. 2000-12-13 22:06:05 +00:00
thorpej df303090c2 First step at integrating ALTQ -- IFQ_*() glue macros that select
old-style queueing or ALTQ based on a compile time option.
2000-12-13 22:05:12 +00:00
thorpej 173c0bb9d7 Include BPF headers as necessary (feh, too many changes to try and
merge...)

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 93292b8aaa do not touch region after free 2000-12-11 07:52:48 +00:00
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).

bouyer 3659b305e5 In vlan_config(), filter flags inherited from parent interface to

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).

2000-10-01 23:32:39 +00:00
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
flag to be directly toggled.

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()).

thorpej b36ce94c6b Convert `gif' to be a cloning interface. 2000-07-02 00:21:42 +00:00
thorpej 1e58f22342 Add the notion of "cloning" of network pseudo-interface (e.g. `gif').
This allows them to be created and destroyed on the fly via ifconfig(8),

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

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)

- 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.

  this facility is used quite a lot in the kernel.

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

darrenr fd7edad6c3 Change the use of pfil hooks. There is no longer a single list of all

which caontains list heads, etc.  The per-protosw pfil struct is passed
to pfil_hook_get(), along with an in/out flag to get the head of the
relevant filter list.  This has been done for only IPv4 and IPv6, at
present, with these patches only enabling filtering for IPPROTO_IP and
IPPROTO_IPV6, although it is possible to have tcp/udp, etc, dedicated
filters now also.  The ipfilter code has been updated to only filter
IPv4 packets - next major release of ipfilter is required for ipv6.

itojun de10c7425e backout incomplete hack from KAME codebase (originally from bbn).
the hack tries to respect ifa or ifp passed to RTM_ADD.  However, the change
broke certain link-layers.  They include:
- midway ethernet card (en*), which uses sockaddr_dl in gateway portion
  to pass PVC information.  with the patch, the gateway portion will be
  overwritten by empty sockaddr_dl and PVC initialization will fail.
- IPv6, which can't set static ND table with the patch (ndp -s), for the
  similar reason as above.

There may be improved hack coming soon, hope the new one does not break others.

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.

bouyer f86517a031 Update protocoles and interfaces stats counters to 64bit.
RTM_IFINFO is now 0xf, 0xe is RTM_OIFINFO which returns the old (if_msghdr14)
struct with 32bit counters (binary compat, conditioned on COMPAT_14).
Same for sysctl: node 3 is renamed NET_RT_OIFLIST, NET_RT_IFLIST is now node 4.
Change rt_msg1() to add an mbuf to the mbuf chain instead of just panic()
when the message is larger than MHLEN.

sommerfeld 7e72e96529 Fix PR7946 (neighbor discovery tries to block at interrupt level).
stack-allocate a sockaddr_storage for the temporary sockaddr rather
than putting it in an mbuf.

neighbor discovery wants to delete expired ifa's from a timeout
handler.  allowing rtinit(RTM_DELETE, ...) to run at interrupt level
allows this to work.
i think we can afford the extra ~128 bytes of stack depth ..

is f546d949b6 Decouple IP mtu for ARCnet devices from interface MTU.
This is important, because for most protocols, link level fragmentation is
used, but with different default effective MTUs. (e.g.: IPv4 default MTU
is 1500 octets, IPv6 default MTU is 9072 octets).

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.

itojun 65363da25e Merge in NetBSD/sh3 from cvs.kame.net repository.
Tree structure:
- sys/arch/sh3: sh3 generic code
	As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).

bouyer 075ea2cfea Fix ifa_ifwithnet() for the netatalk case: netatalk uses blocks of addresses
which can't be handled by netmask, and ifa_ifwithnet() didn't find the
interface associated with an adress if it was in the same block but not with
the same prefix. This prevented 'route add' and atalkd to work properly
with some network configs.
This has been discussed on tech-net some weeks ago.

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.
