* This checkin addresses a couple of issues:Qing Li2008-12-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. The "route" command allows route insertion through the interface-direct option "-iface". During if_attach(), an sockaddr_dl{} entry is created for the interface and is part of the interface address list. This sockaddr_dl{} entry describes the interface in detail. The "route" command selects this entry as the "gateway" object when the "-iface" option is present. The "arp" and "ndp" commands also interact with the kernel through the routing socket when adding and removing static L2 entries. The static L2 information is also provided through the "gateway" object with an AF_LINK family type, similar to what is provided by the "route" command. In order to differentiate between these two types of operations, a RTF_LLDATA flag is introduced. This flag is set by the "arp" and "ndp" commands when issuing the add and delete commands. This flag is also set in each L2 entry returned by the kernel. The "arp" and "ndp" command follows a convention where a RTM_GET is issued first followed by a RTM_ADD/DELETE. This RTM_GET request fills in the fields for a "rtm" object, which is reinjected into the kernel by a subsequent RTM_ADD/DELETE command. The entry returend from RTM_GET is a prefix route, so the RTF_LLDATA flag must be specified when issuing the RTM_ADD/DELETE messages. 2. Enforce the convention that NET_RT_FLAGS with a 0 w_arg is the specification for retrieving L2 information. Also optimized the code logic. Reviewed by: julian Notes: svn path=/head/; revision=186500

* This main goals of this project are:Qing Li2008-12-151-16/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. separating L2 tables (ARP, NDP) from the L3 routing tables 2. removing as much locking dependencies among these layers as possible to allow for some parallelism in the search operations 3. simplify the logic in the routing code, The most notable end result is the obsolescent of the route cloning (RTF_CLONING) concept, which translated into code reduction in both IPv4 ARP and IPv6 NDP related modules, and size reduction in struct rtentry{}. The change in design obsoletes the semantics of RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland applications such as "arp" and "ndp" have been modified to reflect those changes. The output from "netstat -r" shows only the routing entries. Quite a few developers have contributed to this project in the past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and Andre Oppermann. And most recently: - Kip Macy revised the locking code completely, thus completing the last piece of the puzzle, Kip has also been conducting active functional testing - Sam Leffler has helped me improving/refactoring the code, and provided valuable reviews - Julian Elischer setup the perforce tree for me and has helped me maintaining that branch before the svn conversion Notes: svn path=/head/; revision=186119
