2000-12-13more random tcp sequence numbers. okay deraadt@, angelos@Niels Provos
2000-12-11nuke #ifdef TCP6 (no longer supported).Jun-ichiro itojun Hagino
validate ICMPv6 too big messages (pmtud) based on pcb. we accept certain amount of non-validated ones, as IPv6 mandates ICMPv6 (so even for traffic from unconnected pcb, we need pmtud). sync with kame
2000-10-14implement net.inet.tcp.rstppslimit. rate-limits outbound TCP RST trafficJun-ichiro itojun Hagino
to less than N per 1 second.
2000-09-19Lots and lots of changes.Angelos D. Keromytis

2000-07-06completely remove ipv4 mapped cases from tcp_input().Jun-ichiro itojun Hagino
cleanup (indentation, v4-or-v6 conditions)
2000-07-05more cleanup for IPv4 mapped address support. there seem to be someJun-ichiro itojun Hagino
inconsistency in corner cases (from NRL I believe). todd (fries) and I have seen panic, with the following call chain: ip6_input -> tcp_input -> tcp_respond -> ip_input -> bang! more cleanups should be done, to decrease complexity. for example, INP_IPV6_MAPPED should be nuked.
2000-06-18permit compilation of non-V6 kernelsTheo de Raadt
2000-06-18support ipv6 for tcp_identBob Beck
2000-06-18for setsockopt/getsockopt, don't assume non-PF_INET6 address family asJun-ichiro itojun Hagino
PF_INET. we may see other family in the future... (pedant)
2000-06-03correctly handle ctlinput messages for IPv6.Jun-ichiro itojun Hagino
1999-12-21option TCP_NEWRENO goes away, its the default case for TCP_SACK ifNiels Provos
SACK is disabled for the connection or via sysctl
1999-12-20decide address family for {set,get}sockopt() by domain table,Jun-ichiro itojun Hagino
not from tcb. it will present more natural behavior. af for socket option obeys address family passed to bind(2).
1999-12-08bring in KAME IPv6 code, dated 19991208.Jun-ichiro itojun Hagino
replaces NRL IPv6 layer. reuses NRL pcb layer. no IPsec-on-v6 support. see sys/netinet6/{TODO,IMPLEMENTATION} for more details. GENERIC configuration should work fine as before. GENERIC.v6 works fine as well, but you'll need KAME userland tools to play with IPv6 (will be bringed into soon).

1999-07-06Added support for TCP MD5 option (RFC 2385).cmetz
1999-07-02Significant cleanups in the way TCP is made to handle multiple networkcmetz
protocols. "struct tcpiphdr" is now gone from much of the code, as are separate pointers for ti and ti6. The result is fewer variables, which is generally a good thing. Simple if(is_ipv6) ... else ... tests are gone in favor of a switch(protocol family), which allows future new protocols to be added easily. This also makes it possible for someone so inclined to re-implement TUBA (TCP over CLNP?) and do it right instead of the kluged way it was done in 4.4. The TCP header template is now referenced through a mbuf rather than done through a data pointer and dtom()ed as needed. This is partly because dtom() is evil and partly because max_linkhdr + IPv6 + TCP + MSS/TS/SACK opts won't fit inside a packet header mbuf, so we need to grab a cluster for that (which the code now does, if needed).
1999-03-24Replace 'in6a_words' (old NRL convention) with 's6_addr32' (new BSDI et al.cmetz
convention that is more common and more specific as to the access size)

draft-mcdonald-simple-ipsec-api, kernel notifies (EMT_REQUESTSA) signal userland key management applications when security services are requested. this is only for outgoing connections at the moment, incoming packets are not yet checked against the selected socket policy.
