1999-04-12Removed TOS support. This simplifies many things a lot.Martin Mares
1999-04-03More changes to the kernel syncer.Martin Mares
o Now compatible with filtering. o Learning of kernel routes supported only on CONFIG_SELF_CONSCIOUS systems (on the others it's impossible to get it semantically correct). o Learning now stores all of its routes in a separate fib and selects the ones the kernel really uses for forwarding packets. o Better treatment of CONFIG_AUTO_ROUTES ports. o Lots of internal changes.
1999-03-29Remember that we can run device syncer without kernel syncerMartin Mares
and vice versa now.
1999-03-27Cleaned up system configuration files -- removed few obsolete parameters,Martin Mares
documented the remaining ones (sysdep/cf/README). Available configurations: o linux-20: Old Linux interface via /proc/net/route (selected by default on pre-2.1 kernels). o linux-21: Old Linux interface, but device routes handled by the kernel (selected by default for 2.1 and newer kernels). o linux-22: Linux with Netlink (I play with it a lot yet, so it isn't a default). o linux-ipv6: Prototype config for IPv6 on Linux. Not functional yet.
1999-03-26Moved to a much more systematic way of configuring kernel protocols.Martin Mares
o Nothing is configured automatically. You _need_ to specify the kernel syncer in config file in order to get it started. o Syncing has been split to route syncer (protocol "Kernel") and interface syncer (protocol "Device"), device routes are generated by protocol "Direct" (now can exist in multiple instances, so that it will be possible to feed different device routes to different routing tables once multiple tables get supported). See doc/bird.conf.example for a living example of these shiny features.
1999-03-24Removed our declaration of RTPROT_BIRD since Alexey has assignedMartin Mares
us a real protocol number in 2.2.4 kernel.
1999-03-04Fixed processing of !krt_capable() routes. Converted device route decisionsMartin Mares
to the krt_capable mechanism as well.
1999-03-04KRT: Implemented asynchronous route / interface state notificationsMartin Mares
(via Netlink). Tweaked kernel synchronization rules a bit. Discovered locking bug in kernel Netlink :-) Future plans: Hunt all the bugs and solve all the FIXME's.
1999-03-04Although there are still heaps of FIXME's, Netlink works.Martin Mares
To build BIRD with Netlink support, just configure it with ./configure --with-sysconfig=linux-21 After it will be tested well enough, I'll probably make it a default for 2.2 kernels (and rename it to linux-22 :)).
1999-03-04Converted some mb_alloc/bzero pairs to mb_allocz.Martin Mares
1999-03-03Netlink scans routes...Martin Mares
1999-03-03Rewrote the kernel syncer. The old layering was horrible.Martin Mares
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.
1999-03-02Netlink module supports interface scan on startup. Working on more.Martin Mares
1999-03-01Implemented netlink protocol parsing functions. More to come tomorrow.Martin Mares
1999-03-01Added skeletal version of Linux netlink interface. It doesn't work yet,Martin Mares
but the framework is there and I'll try finish it soon.
