Adds support for several Linux kernel route attributes.

c429d4a4 04/04/2010 01:41 PM Ondrej Zajicek

Restrict export of device routes to the kernel protocol.

In usual configuration, such export is already restricted
with the aid of the direct protocol but there are some
races that can circumvent it. This makes it harder to
break kernel device routes. Also adds an option to...

Many changes in (mainly) kernel syncers.

- BSD kernel syncer is now self-conscious and can learn alien routes
- important bugfix in BSD kernel syncer (crash after protocol restart)
- many minor changes and bugfixes in kernel syncers and neighbor cache
- direct protocol does not generate host and link local routes...

Add 'primary' configuration option.

Cleaned up debugging in kernel syncer. Netlink has still LOCAL_DEBUG
turned on, but after some testing I'll gag it.

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.

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. :)

Removed one unused structure field.

c10421d3 04/03/1999 01:05 PM Martin Mares

More changes to the kernel syncer.

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...

Moved to a much more systematic way of configuring kernel protocols.

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...

KRT: Implemented asynchronous route / interface state notifications
(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.

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)...
025d14cd 03/01/1999 07:05 PM Martin Mares

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

013a9b91 02/13/1999 08:46 PM Martin Mares

When shutting down, remove all routes (except for RTS_INHERIT and RTS_DEVICE
routes) from kernel routing tables unless the "persist" switch is set.

10d807d0 02/05/1999 09:38 PM Martin Mares

Synced kernel interface to new interface.

8e66a0eb 12/08/1998 06:37 PM Martin Mares

Hopefully finished kernel syncer (krt) rewrite:

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...

Rewritten kernel syncer. Now uses the rta trickery I've introduced yesterday
and does things "the right way". Few things are still missing (device
routes etc.), I'll add them later in the evening.

12df4d90 12/07/1998 10:15 AM Martin Mares

KRF_* flags moved to krt.h as they are internal to kernel syncer,
fib->pad0,pad1 renamed to x0,x1 and in case of struct net x0 is reserved
for kernel syncing as well.

980ffedb 12/06/1998 05:40 PM Martin Mares

Kernel syncer is now configurable. It will probably need some more
options, but at least basic tuning is possible now.

7e7790c6 10/18/1998 12:50 PM Martin Mares

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 ;-)
