martin 71d020f371 Since we decided "const struct mbuf *" would not do the right thing (tm), 
remove ~all const from mbuf pointers.

tron 41dcb3a310 Remove type casts and lint directives which are now longer necessary 
because the first argument of m_copydata() is "const struct mbuf *" now.

kim c9f56c04dc Add RFC 3378 EtherIP support, ported from OpenBSD to NetBSD by 
Hans Rosenfeld (rosenfeld at grumpf.hope-2000.org)

This change makes it possible to add gif interfaces to bridges, which
will then send and receive IP protocol 97 packets. Packets are Ethernet
frames with an EtherIP header prepended.

peter b9c49ebff1 Change ifc_destroy to return an int instead of void, so that it 
can pass back errors to ifconfig.

christos 0f7d471853 Factor out the hand-crafting of mbufs from the interface files. Reviewed by 
gimpy. XXX: I could have used bpf_mtap2 on some of the new functions, but I
chose not to, because I just wanted to do what amounts to a code move.

itojun 00f97b0202 drop too short IPv6 frame 2002-06-13 05:10:34 +00:00
christos 5c8e181780 We are not guaranteed that we have enough bytes to get a struct ip from our 
mbuf. So if we receive a short packet, that looks like gif we would panic.
Reviewed by thorpej, tested by Kimmo Suominen and Andreas Wrede. Thanks for
the help in tracking this down.

now: if_lastchange get updated when IFF_UP is changed.

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).

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.

with ip proto #41).

itojun 2042e749ad for gif interface, sync IFF_RUNNING with IFF_UP. it does not 
make sense to leave IFF_RUNNING during !IFF_UP (it is pseudo interface
