2010-07-05Implements hostcache and recursive next hops.Ondrej Zajicek
Hostcache is a structure for monitoring changes in a routing table that is used for routes with dynamic/recursive next hops. This is needed for proper iBGP next hop handling.
2009-09-30Fixes one previous commit.Ondrej Zajicek
2009-09-24Do not allow gateway routes with NULL iface.Ondrej Zajicek
2000-06-01Updated for new scope handling.Martin Mares
Also, provide proper address scopes in struct ifa.
2000-04-01Include "lib/string.h" instead of <string.h>. It should give us bzero()Martin Mares
and other non-portable functions on all systems.
2000-03-12Cleaned up debugging in kernel syncer. Netlink has still LOCAL_DEBUGMartin Mares
turned on, but after some testing I'll gag it.
1999-12-16Minor cleanups.Martin Mares
1999-11-04Renamed attr->attrs to attr->eattrs.Martin Mares
1999-08-03Kernel route syncer supports multiple tables.Martin Mares
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. :)
1999-05-17Kill remaining master_table relics in KRT code.Martin Mares
Make all protocols pass routing table to rte_update and rte_discard.
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.
1999-03-04KRT: 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.
1999-03-04Converted some mb_alloc/bzero pairs to mb_allocz.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.
1999-02-13Squashed one bug in timing of route scans.Martin Mares
1999-02-05Synced Linux sysdeps to new interface.Martin Mares
1998-12-20die() -> bug() where appropriate.Martin Mares
1998-12-08Hopefully finished kernel syncer (krt) rewrite:Martin Mares
o Interface syncing is now a part of krt and it can have configurable parameters. Actually, the only one is scan rate now :) o Kernel routing table syncing is now synchronized with interface syncing (we need the most recent version of the interface list to prevent lots of routes to non-existent destinations from appearing). Instead of its own timer, we just check if it's route scan time after each iface list scan. o Syncing of device routes implemented. o CONFIG_AUTO_ROUTES should control syncing of automatic device routes. o Rewrote krt_remove_route() to really remove routes :) o Better diagnostics. o Fixed a couple of bugs.
1998-12-08Rewritten kernel syncer. Now uses the rta trickery I've introduced yesterdayMartin Mares
and does things "the right way". Few things are still missing (device routes etc.), I'll add them later in the evening.
1998-12-07Comparison of kernel reject routes fixed.Martin Mares
1998-12-06Kernel syncer is now configurable. It will probably need some moreMartin Mares
options, but at least basic tuning is possible now.
1998-10-20Learn static device routes from the kernel (temporary until we can makeMartin Mares
such things configurable).
1998-10-19Basic kernel routing table syncing implemented. Learning of routes installedMartin Mares
by other programs or the kernel itself is not supported yet, but it's not needed for development of other protocols.
1998-10-19We parse /proc/net/route and flag RT entries according to it. More to comeMartin Mares
today in the morning...
1998-10-18Since almost every UNIX system requires different techniques for readingMartin Mares
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 ;-)
