itojun 8b646a5273 remove IPV6FIREWALL case, which is never used 2001-06-11 13:49:18 +00:00
itojun f4e4c674a7 disallow userland programs from specifying addresses with IPV6_PKTINFO
setsockopt, if:
- the address is not verified by DAD (= not ready)
- the address is an anycast address (= not permitted as source)

itojun 92969654c0 enable FAKE_LOOPBACK_IF case by default.
now traffic on loopback interface will be presented to bpf as normal wire
format packet (without KAME scopeid in s6_addr16[1]).

fix KAME PR 250 (host mistakenly accepts packets to fe80::x%lo0).

itojun e1f4f77960 to sync with kame better, (1) remove register declaration for variables,
(2) sync whitespaces, (3) update comments. (4) bring in some of portability
and logging enhancements.  no functional changes here.

itojun 617b3fab7e - record IPsec packet history into m_aux structure.
- let ipfilter look at wire-format packet only (not the decapsulated ones),
  so that VPN setting can work with NAT/ipfilter settings.

TODO: use header history for stricter inbound validation
2001-01-24 09:04:15 +00:00
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.

- use latest source address selection code - in6_src.c.
- correct frag header insertion.
- deep copy ip6 header portion in ip6_mloopback to avoid overwrite.
- do not bark when we forward packet to loopback.
- some cosmetics.

itojun 48c5048502 correct manipulation of link-local scoped address on loopback.
now "telnet fe80::1%lo0" should work again.
(we have another bug near here - will attack it soon)

thorpej f636538446 NULL != 0 2000-05-19 04:34:39 +00:00
itojun fa5c89d64a do not mistakingly forward link-local scoped packet (the bug was added
with "beyondscope" icmp6 support).
"options FAKE_LOOPBACK_IF" will honor scope on loopback outputs.  rcvif will
be real interface, not the loopback, just like when multicast loopback.

simonb 56fba1c4d0 Remove duplicate declaration of ifindex2ifnet - it's in <net/if.h>. 2000-03-29 03:38:53 +00:00
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)

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.

itojun 1a2a1e2b1f bring in latest KAME ipsec tree.
- interop issues in ipcomp is fixed
- padding type (after ESP) is configurable
- key database memory management (need more fixes)

XXX m->m_pkthdr.rcvif is still overloaded - hope to fix it soon

itojun b3761abef8 remove extra portability #ifdef (like #ifdef __FreeBSD__) in KAME IPv6/IPsec
code, from netbsd-current repository.
#ifdef'ed version is always available from ftp.kame.net.

XXX please do not make too many diff-unfriendly changes, we'll need to take
bunch of diffs on upgrade...

itojun 2e904aec57 make IPV6_BINDV6ONLY setsockopt available. it controls behavior of
AF_INET6 wildcard listening socket.  heavily documented in ip6(4).
net.inet6.ip6.bindv6only defines default value.  default is 1.

"options INET6_BINDV6ONLY" removes any code fragment that supports
IPV6_BINDV6ONLY == 0 case (not defopt'ed as use of this is rare).

itojun ea861f0183 sync IPv6 part with latest KAME tree. IPsec part is left unmodified
due to massive changes in KAME side.
- IPv6 output goes through nd6_output
- faith can capture IPv4 packets as well - you can run IPv4-to-IPv6 translator
  using heavily modified DNS servers
- per-interface statistics (required for IPv6 MIB)
- interface autoconfig is revisited
- udp input handling has a big change for mapped address support.
- introduce in4_cksum() for non-overwriting checksumming
- introduce m_pulldown()
- neighbor discovery cleanups/improvements
- netinet/in.h strictly conforms to RFC2553 (no extra defs visible to userland)
- IFA_STATS is fixed a bit (not tested)
- and more more more.

TODO:
- cleanup os-independency #ifdef
- avoid rcvif dual use (for IPsec) to help ifdetach

(sorry for jumbo commit, I can't separate this any more...)
