itojun dfb1429789 unifdef OLDIP6OUTPUT 2001-10-17 08:23:05 +00:00
itojun 4d51fe368b change the meaning of ifnet.if_lastchange to meet RFC1573 ifLastChange.
follows BSD/OS practice and ucd-snmp code (FreeBSD does it for specific
interfaces only).

was: if_lastchange get updated on every packet transmission/receipt.
now: if_lastchange get updated when IFF_UP is changed.

thorpej bf2dcec4f5 Remove the use of splimp() from the NetBSD kernel. splnet()
and only splnet() is allowed for the protection of data structures
used by network devices.

thorpej fc5dafc79b Fix a rather annoying problem where the sockaddr_dl which holds
the link level name for the interface (ifp->if_sadl) is allocated
before ifp->if_addrlen is initialized, which could lead to allocating
too little space for the link level address.

Do this by splitting allocation of the link level name out of
if_attach() and into if_alloc_sadl(), which is normally called
by functions like ether_ifattach().  Network interfaces which
don't have a link-specific attach routine must call if_alloc_sadl()
themselves (example: gif).

Link level names are freed by if_free_sadl(), which can be called
from e.g. ether_ifdetach().  Drivers never need call if_free_sadl()
themselves as if_detach() will do it if it is not already done.

While here, add the ability to pass an AF_LINK address to
SIOCSIFADDR in ether_ioctl() (this is what caused me to notice
the problem that the above fixes).

thorpej ed7695a765 Fill in if_dlt. 2000-12-18 19:44:33 +00:00
thorpej c5293456da Adapt to bpfattach() changes, and further centralize the bpfattach()
and bpfdetach() calls into link-type subroutines where possible.

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).

augustss c1ebd1929a Kill some more register declarations. 2000-03-30 09:45:33 +00:00
frueauf 176df8913d Make this compile again:
NEWIP6OUTPUT gets no longer defined, revers logic to use OLDIP6OUTPUT.

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).
1999-09-25 17:49:27 +00:00
is 6a793d8a47 Zeroth version of IPv6 support for ARCnet. Correct MTU handling still needs
to be done.
1999-09-19 21:31:33 +00:00
is 3e419f86dc Move the mtu initialization to arc_storelladdr, so that it will be upped
again when switching link0 on.
XXX This stuff needs to be thought about, especially with the doomming IPv6
support, which uses yet another default mtu.

is df8d07f87e Don't assume PHDS encoding for DIAGNOSE packets... we have to pass them
raw, if used at all.
1999-08-27 19:38:29 +00:00
is d8c7407afe Factor out arc_storelladdr(), and use that instead of arc_ifattach() in
the bah_reset() function.
This makes the last change work without deconnecting all the other interfaces
from the interface list.

Problem detected by Andreas Johansson.

is c7acd44cf0 Eliminate a function call... we know its exactly one byte here 1999-08-26 19:56:08 +00:00
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.
1999-05-18 23:52:51 +00:00
is 06420a5af7 So... after all, the ATA878.2 copy I had was buggy. The newer revision has
this fixed in the figures (but still not in the text); anyway, the intention
of the ATA is that this is identical to the PHDS specification.
Remove the ...EXC_8782 constant, and change the _EXC_1201 constant to be
a simple ...EXC.

is 5854b4eafe Yet another performance optimization for exceptional length ARCnet packets.
This time in the receive path.
1999-01-16 14:08:05 +00:00
is f77decf65c Make the code path for exceptional length packets a bit faster (2 mbuf
operations less) and better readable.

is fabb33431c Reimplement a test for broadcast addresses advertized, which was left out
when rewriting the ARP system.
1997-10-02 19:41:56 +00:00
is 4555777c80 Fix several bugs related to the new ARP code, and ARCnet ARP support.
Among other, add ARPHRD_ARCNET definition, make sure the hardware type is
set on outgoing ARP packets, make sure we dont send out replies as broadcasts.
1997-03-23 01:22:35 +00:00

is 57f2f47e2c move if_arc.h to sys/net 1997-03-16 23:27:07 +00:00
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.

is 905db38340 Add IP multicast support as per RFC 1122 section 3.3.7 to ARCnet.
"The mapping of IP Class D addresses to local addresses is
         currently specified for the following types of networks:
	 [...]
         o    Any network that supports broadcast but not multicast,
              addressing: all IP Class D addresses map to the local
              broadcast address."

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.

is a5ba4721eb Don't even check the not-yet-initialized mbuf pointers for being !=
NULL in the error exit code of arc_output(), else we see random data
and try to m_freem() it, panic'ing the machine.
