Raw Normal View History

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.

#ifdef CONFIG_LINUX_SCAN
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 ;-)

krt-scan.c
krt-scan.h
Use traditional Unix route/iface interface only when CONFIG_NETLINK is not defined. Also moved declarations of Unix iface logic to krt.h.

#endif
Tried to clean up multicast handling. Now we don't try to guess multicast abilities depending on definedness of symbols and use hard-wired system-dependent configuration defines instead. Please test whereever you can.
