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.

thorpej 1ffa60ac01 Use macros from tcp_timer.h to manipulate TCP timers, so that their
implementation can be changed easily.

matt 334f006538 New TCP reassembly code. The new code reduces the memory needed by
out-of-order packets and builds the infrastructure needed for sending
SACK blocks (to be added shortly).

kml fcf0227962 Fix to ensure that the correct MSS is advertised for loopback
TCP connections by using the MTU of the interface.  Also added
a knob, mss_ifmtu, to force all connections to use the MTU of
the interface to calculate the advertised MSS.

thorpej 5837cc6b07 Update copyright (sigh, should have done this long ago). 1998-02-19 02:36:42 +00:00
thorpej e5e283e02d Finishing merging 4.4BSD-Lite2 netinet. At this point, the only changes
left were SCCS IDs and Copyright dates.

thorpej 2e85747e9e From 4.4BSD-Lite2 (noted by Frank van der Linden):
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time.  However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere).  Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

thorpej ee84a26869 After further examination of traces of bulk transfers (with help from
Kevin Lahey), undo the "defer window update until next delayed ACK".

thorpej c02a72fcd0 Implement an infrastructure to allow larger initial congestion windows.
The sysctl'able variable "tcp_init_win", when set to 0, selects an
auto-tuning algorithm for selecting the initial window, based on transmit
segment size, per discussion in the IETF tcpimpl working group.

Default initial window is still 1 segment, but will soon become 2 segments,
per discussion in tcpimpl.

thorpej 3026b32ab3 In the PRU_RCVD entry point, if TF_DELACK is set, don't send the window
update now, since it will be sent within 200ms when the delayed ACK is
sent.  Instrument how many hits we get on this optimization.

kleink 8fb48a5db9 Eliminate a superflouus `if' statement: when detaching the TCP protocol from
a socket, just calling tcp_disconnect() on the tcpcb will do the right thing.
