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).

jdolecek c42f28d24a Since last duplicate prototype cleanup, we need to include
<netinet/ip_mroute.h> to get ip_mforward() prototype if MROUTING
is defined.

thorpej 66470ad12d Pull in <sys/callout.h> for the benefit of userland. 2000-03-24 22:40:11 +00:00
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.

itojun 19b198e8c2 improve comment (about undo'ing code on in{,6}_ifinit failure) 2000-03-21 11:23:31 +00:00
itojun d926d6fa47 #if 0'ed undo code for interface address addition failure.
it was a bit too strong, and forbids multiple addresses from
same prefix to be assigned.

now the behavior is the same as previous - memory leak on interface address
addition failure.

IP options.  Problem pointed out by Matt Hargett and Erik Fair, analyzed
by me.

itojun 04ac848d6f introduce m->m_pkthdr.aux to hold random data which needs to be passed
between protocol handlers.

ipsec socket pointers, ipsec decryption/auth information, tunnel
decapsulation information are in my mind - there can be several other usage.
at this moment, we use this for ipsec socket pointer passing.  this will
avoid reuse of m->m_pkthdr.rcvif in ipsec code.

due to the change, MHLEN will be decreased by sizeof(void *) - for example,
for i386, MHLEN was 100 bytes, but is now 96 bytes.
we may want to increase MSIZE from 128 to 256 for some of our architectures.

take caution if you use it for keeping some data item for long period
of time - use extra caution on M_PREPEND() or m_adj(), as they may result
in loss of m->m_pkthdr.aux pointer (and mbuf leak).

this will bump kernel version.

(as discussed in tech-net, tested in kame tree)

itojun 1450d6e643 bring in recent KAME changes (only important and stable ones, as usual).
- remove net.inet6.ip6.nd6_proxyall.  introduce proxy NDP code works
  just like "arp -s".
- revise source address selection.
  be more careful about use of yet-to-be-valid addresses as source.
- as router, transmit ICMP6_DST_UNREACH_BEYONDSCOPE against out-of-scope
  packet forwarding attempt.
- path MTU discovery takes care of routing header properly.
- be more strict about mbuf chain parsing.

itojun 3c0960474d reject non-AF_INET addresses on ioctl.
without this, we can configure invalid sockaddrs, for example,
sa_family == 0 (and we can never remove them!)

darrenr 4b3916780b pass "struct pfil_head *" to pfil_add_hook and pfil_remove hook rather
than "struct protosw *".
2000-02-20 00:56:33 +00:00
darrenr fd7edad6c3 Change the use of pfil hooks. There is no longer a single list of all
pfil information, instead, struct protosw now contains a structure
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.
