Use more specific sockaddr type for inpcb notify. in_pcbnotifyall() is an IPv4 only function. All callers check that sockaddr dst is in fact a sockaddr_in. Pass the more spcific type and remove the runtime check at beginning of in_pcbnotifyall(). Use const sockaddr_in in in_pcbnotifyall() and const sockaddr_in6 in6_pcbnotify() as dst parameter.

Convert tcp_now() time counter to 64 bit. After changing tcp now tick to milliseconds, 32 bits will wrap around after 49 days of uptime. That may be a problem in some places of our stack. Better use a 64 bit counter. As timestamp option is 32 bit in TCP protocol, use the lower 32 bit there. There are casts to 32 bits that should behave correctly. Start with random 63 bit offset to avoid uptime leakage. 2^63 milliseconds result in 2.9*10^8 years of possible uptime. OK yasuoka@

To avoid misunderstanding, keep variables for tcp keepalive in milliseconds, which is the same unit of tcp_now(). However, keep the unit of sysctl variables in seconds and convert their unit in tcp_sysctl(). Additionally revert TCPTV_SRTTDFLT back to 3 seconds, which was mistakenly changed to 1.5 seconds by tcp_timer.h 1.19. ok claudio

Modify TCP receive buffer size auto scaling to use the smoothed RTT (SRTT) instead of the timestamp option. Since the timestamp option is disabled on some OSs (eg. Windows) or dropped by some firewalls/routers, in such a case the window size had been fixed at 16KB, this limits throughput at very low on high latency networks. Also replace "tcp_now" from 2HZ tick counter to binuptime in milliseconds to calculate the SRTT better. tested by krw matthieu jmatthew dlg djm stu stsp ok claudio

Accept reject and blackhole routes for IPsec PMTU discovery. Since revision 1.87 of ip_icmp.c icmp_mtudisc_clone() ignored reject routes. Otherwise TCP would clone these routes for PMTU discovery. They will not work, even after dynamic routing has found a better route than the reject route. With IPsec the use case is different. First you need a route, but then the flow handles the packet without routing. Usually this route should be a reject route to avoid sending unencrypted traffic if the flow is missing. But IPsec needs this route for PMTU discovery, so use it for that. OK claudio@ tobhe@

There was a race in the TCP timers. As they may sleep to grab the netlock, timers may still run after they have been disarmed. Deleting the timeout is not sufficient to cancel them, but the code from 4.4 BSD is assuming this. The solution is to add a flag for every timer to see whether it has been armed or canceled. Remove the TF_DEAD check as tcp_canceltimers() is called before the reaper timer is fired. Cancelation works reliably now. OK mpi@

The TCP reaper timeout was still imlemented as soft timeout. So it could run immediately and was not synchronized with the TCP timeouts, although that was the intension when it was introduced in revision 1.85. Convert the reaper to an ordinary TCP timeout so it is scheduled on the same timeout thread after all timeouts have finished. A net lock is not necessary as the process calling tcp_close() will not access the tcpcb after arming the reaper timeout. OK mikeb@

Fix the naming of interfaces and variables for rdomains and rtables and make it possible to bind sockets (including listening sockets!) to rtables and not just rdomains. This changes the name of the system calls, socket option, and ioctl. After building with this you should remove the files /usr/share/man/cat2/[gs]etrdomain.0.

Merge in -current from two days ago in the SMP branch. As usual with merges, they do not indicate progress, so do not hold your breath for working SMP, and do not mail me and ask about the state of it. It has not changed. There is work ongoing, but very, very slowly. The commit is done in parts as to not lock up the tree in too big chunks at a time.

Fix tcp retransmit/persist timers, provos@ OK.
Adapted from NetBSD:
Fix a retransmission bug introduced by the Brakmo and Peterson
RTO estimation changes. Under some circumstances it would
return a value of 0, while the old Van Jacobson RTO code would
return a minimum of 3. This would result in 12 retransmissions,
each 1 second apart. This takes care of those instances, and
ensures that t_rttmin is used everywhere as a lower bound.

Significant cleanups in the way TCP is made to handle multiple network 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).

From Tom Henderson <tomh@cs.berkeley.edu>: Fixed a sequence wraparound bug in the snd_recover variable discovered in very large (multiple GByte) transfers (in loss free conditions, snd_recover was not sufficiently tracking snd_una). Thanks to Mark Smith for finding this. Fixed a bug in tcp_newreno that was preventing retransmission of data due to partial acks. (Discovered by Jayanth Vijayaraghavan)

fix NEWRENO behaviour, the newreo code assumed that the send socket buffer has already been cleared of the acked data, though it was called before any sbdrop() call and always called tcp_output() with 0 index in the send socket buffer and thus causing data corruption. so do not set snd_una to th_ack.
