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.
sync with kame.

itojun 6562709f3a typo fix. PR 11889 2001-01-04 11:48:44 +00:00
itojun 9183e2dc4e remove #ifdef TCP6. it is not likely for us to bring in sys/netinet6/tcp6*.c
(separate TCP/IPv6 stack) into netbsd-current.

itojun 89f53512af use real wallclock (got by microtime) to compute IPsec database lifetimes.
previous code used interval timers, and had problem with suspend/resume.

itojun 5e8b5a35e4 make ipsec_strerror(3) to return const char *, not char *. sync with kame. 2000-07-30 02:38:35 +00:00
itojun 90ca25568b remove obsolete sysctl MIB net.inet.ipsec.inbound_call_ike.

itojun d7e34999be sync with recent kame.
avoid use of macros to manipulate sockaddrs (hides error case too much).
correct IPv4 packet handling when ip option is present.
preparations for ipsec policy engine upgrades.

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 bbe25244d0 remove some of cross-BSD portability #ifdef.
remove xxCTL_VARS, which is BSDI specific.

itojun 90736ab608 fix include pathname for better rfc2292 compliance. 2000-02-06 12:49:37 +00:00
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)
- policy specification is revisited

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...

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.

itojun 70ada0957e sync with recent KAME.
- loosen ipsec restriction on packet diredtion.
- revise icmp6 redirect handling on IsRouter bit.
- tcp/udp notification processing (link-local address case)
- cosmetic fixes (better code share across *BSD).

thorpej 267920eb1a defopt INET6, and put it in opt_inet.h (most places already include this
file, which is why the file list is so short).

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.

NOTE: this branch (kame) is used just for refernce.  this may not compile
due to multiple reasons.
