Since almost every UNIX system requires different techniques for reading the kernel routing table as opposed to modifying it which is approximately the same on non-netlink systems, I've split the kernel routing table routines to read and write parts. To be implemented later ;-) 1998-10-18 20:50:43 +08:00			`/*`
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			`* BIRD -- Unix Kernel Route Syncer -- Setting`

Kernel route syncer now supports dynamic reconfiguration. Also it doesn't depend on the startup counter hack now and uses a zero-time timer instead to make itself scheduled after normal protocol startup. 2000-01-18 18:39:30 +08:00			`* (c) 1998--2000 Martin Mares <mj@ucw.cz>`

Synced kernel interface to new interface. 1999-02-06 05:38:50 +08:00			`struct krt_set_status {`

Marked unused parameters in sysdep code as such. 2004-06-05 17:11:07 +08:00			`static inline int krt_set_params_same(struct krt_set_params o UNUSED, struct krt_set_params n UNUSED) { return 1; }`
Implements protocol templates. Based on the patch from Alexander V. Chernikov. Extended to support almost all protocols. Uses 'protocol bgp NAME from TEMPLATE { ... }' syntax. 2011-11-07 07:31:23 +08:00			`static inline void krt_set_copy_params(struct krt_set_params d UNUSED, struct krt_set_params s UNUSED) { }`
