Rewrote the kernel syncer. The old layering was horrible. The new kernel syncer is cleanly split between generic UNIX module and OS dependent submodules: - krt.c (the generic part) - krt-iface (low-level functions for interface handling) - krt-scan (low-level functions for routing table scanning) - krt-set (low-level functions for setting of kernel routes) krt-set and krt-iface are common for all BSD-like Unices, krt-scan is heavily system dependent (most Unices require /dev/kmem parsing, Linux uses /proc), Netlink substitues all three modules. We expect each UNIX port supports kernel routing table scanning, kernel interface table scanning, kernel route manipulation and possibly also asynchronous event notifications (new route, interface state change; not implemented yet) and build the KRT protocol on the top of these primitive operations. 1999-03-04 03:49:56 +08:00			`/*`

Removed the `async' switch which was used for debugging only anyway. Don't moan when netlink reports lost packets. 2000-05-08 20:05:55 +08:00			`* (c) 1999--2000 Martin Mares <mj@ucw.cz>`

Kernel route syncer supports multiple tables. The changes are just too extensive for lazy me to list them there, but see the comment at the top of sysdep/unix/krt.c. The code got a bit more ifdeffy than I'd like, though. Also fixed a bunch of FIXME's and added a couple of others. :) 1999-08-04 03:33:22 +08:00			`CF_KEYWORDS(ASYNC, KERNEL, TABLE)`
