Refactor in_cksum/in4_cksum/in6_cksum implementations: - All three functions are included in the kernel by default. They call a backend function cpu_in_cksum after possibly computing the checksum of the pseudo header. - cpu_in_cksum is the core to implement the one-complement sum. The default implementation is moderate fast on most platforms and provides a 32bit accumulator with 16bit addends for L32 platforms and a 64bit accumulator with 32bit addends for L64 platforms. It handles edge cases like very large mbuf chains (could happen with native IPv6 in the future) and provides a good base for new native implementations. - Modify i386 and amd64 assembly to use the new interface. This disables the MD implementations on !x86 until the conversion is done. For Alpha, the portable version is faster.

Add a source-address selection policy mechanism to the kernel. Also, add ioctls SIOCGIFADDRPREF/SIOCSIFADDRPREF to get/set preference numbers for addresses. Make ifconfig(8) set/display preference numbers. To activate source-address selection policies in your kernel, add 'options IPSELSRC' to your kernel configuration. Miscellaneous changes in support of source-address selection: 1 Factor out some common code, producing rt_replace_ifa(). 2 Abbreviate a for-loop with TAILQ_FOREACH(). 3 Add the predicates on IPv4 addresses IN_LINKLOCAL() and IN_PRIVATE(), that are true for link-local unicast (169.254/16) and RFC1918 private addresses, respectively. Add the predicate IN_ANY_LOCAL() that is true for link-local unicast and multicast. 4 Add IPv4-specific interface attach/detach routines, in_domifattach and in_domifdetach, which build #ifdef IPSELSRC. See in_getifa(9) for a more thorough description of source-address selection policy.

Modular (I tried ;-) TCP congestion control API. Whenever certain conditions happen in the TCP stack, this interface calls the specified callback to handle the situation according to the currently selected congestion control algorithm. A new sysctl node was created: net.inet.tcp.congctl.{available,selected} with obvious meanings. The old net.inet.tcp.newreno MIB was removed. The API is discussed in tcp_congctl(9). In the near future, it will be possible to selected a congestion control algorithm on a per-socket basis. Discussed on tech-net and reviewed by <yamt>.

Commit TCP SACK patches from Kentaro A. Karahone's patch at: http://www.sigusr1.org/~kurahone/tcp-sack-netbsd-02152005.diff.gz Fixes in that patch for pre-existing TCP pcb initializations were already committed to NetBSD-current, so are not included in this commit. The SACK patch has been observed to correctly negotiate and respond, to SACKs in wide-area traffic. There are two indepenently-observed, as-yet-unresolved anomalies: First, seeing unexplained delays between in fast retransmission (potentially explainable by an 0.2sec RTT between adjacent ethernet/wifi NICs); and second, peculiar and unepxlained TCP retransmits observed over an ath0 card. After discussion with several interested developers, I'm committing this now, as-is, for more eyes to use and look over. Current hypothesis is that the anomalies above may in fact be due to link/level (hardware, driver, HAL, firmware) abberations in the test setup, affecting both Kentaro's wired-Ethernet NIC and in my two (different) WiFi NICs.

Reduces the resources demanded by TCP sessions in TIME_WAIT-state using methods called Vestigial Time-Wait (VTW) and Maximum Segment Lifetime Truncation (MSLT). MSLT and VTW were contributed by Coyote Point Systems, Inc. Even after a TCP session enters the TIME_WAIT state, its corresponding socket and protocol control blocks (PCBs) stick around until the TCP Maximum Segment Lifetime (MSL) expires. On a host whose workload necessarily creates and closes down many TCP sockets, the sockets & PCBs for TCP sessions in TIME_WAIT state amount to many megabytes of dead weight in RAM. Maximum Segment Lifetimes Truncation (MSLT) assigns each TCP session to a class based on the nearness of the peer. Corresponding to each class is an MSL, and a session uses the MSL of its class. The classes are loopback (local host equals remote host), local (local host and remote host are on the same link/subnet), and remote (local host and remote host communicate via one or more gateways). Classes corresponding to nearer peers have lower MSLs by default: 2 seconds for loopback, 10 seconds for local, 60 seconds for remote. Loopback and local sessions expire more quickly when MSLT is used. Vestigial Time-Wait (VTW) replaces a TIME_WAIT session's PCB/socket dead weight with a compact representation of the session, called a "vestigial PCB". VTW data structures are designed to be very fast and memory-efficient: for fast insertion and lookup of vestigial PCBs, the PCBs are stored in a hash table that is designed to minimize the number of cacheline visits per lookup/insertion. The memory both for vestigial PCBs and for elements of the PCB hashtable come from fixed-size pools, and linked data structures exploit this to conserve memory by representing references with a narrow index/offset from the start of a pool instead of a pointer. When space for new vestigial PCBs runs out, VTW makes room by discarding old vestigial PCBs, oldest first. VTW cooperates with MSLT. It may help to think of VTW as a "FIN cache" by analogy to the SYN cache. A 2.8-GHz Pentium 4 running a test workload that creates TIME_WAIT sessions as fast as it can is approximately 17% idle when VTW is active versus 0% idle when VTW is inactive. It has 103 megabytes more free RAM when VTW is active (approximately 64k vestigial PCBs are created) than when it is inactive.
