...
state machines. Full explanation will follow soon.

Oops, previous modification for passing NULL to fib_init() did not
...
compile :-(.

When printing a routing table, fib_check() it.
1998-12-20 14:01:37 +00:00

Rewrote fib functions to make them insert/delete/asynchronous-walk safe.
...
This is implemented in a way similar to lib/slists.h, but it took some
more effort to make rehashing not disturb the readers. We do it by just
taking _highest_ k bits of ipa_hash as our hash value and sorting each
box by whole ipa_hash().
Consult FIB_ITERATE_* macros in nest/route.h.
Implemented fib_check() debugging function and also rewrote the rehashing
algorithm to use better thresholds and not to waste time by rehashing
forth and back.

Added source RTS_DUMMY for temporary routes. They should never appear
...
in the main table.

Minor rte/rta interface changes:
...
o rte can now contain a pointer to both cached and uncached rta. Protocols
which don't need their own attribute caching can now just fill-in a rta,
link it to rte without any calls to attribute cache and call rte_update()
which will replace rte->attrs by a cached copy.
o In order to support this, one of previously pad bytes in struct rta
now holds new attribute flags (RTAF_CACHED). If you call rte_update()
with uncached rta, you _must_ clear these flags. In other cases rta_lookup()
sets it appropriately.
o Added rte_free() which is useful when you construct a rte and then the
circumstances change and you decide not to use it for an update. (Needed
for temporary rte's in kernel syncer...)
1998-12-07 21:59:15 +00:00
Martin Mares
12df4d909b
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.
1998-12-07 10:15:42 +00:00

Removed protocol-specific data in rte for protocol static since no

such data ever existed.

Name cleanups as suggested by Pavel:
...
- cfg_strcpy() -> cfg_strdup()
- mempool -> linpool, mp_* -> lp_* [to avoid confusion with memblock, mb_*]
Anyway, it might be better to stop ranting about names and do some *real* work.

Rip now has configurable per-interface metric (please rewiev), and few
...
more configurable parameters. To do that, union was added into iface_patt.
1998-12-04 11:45:51 +00:00
Martin Mares
50d8424ad1
Added configuration of the device internal protocol. This is primarily
...
intended to serve as an example of interface pattern list use. As a side
effect, you can disable generating of device routes by disabling
this protocol.
1998-11-29 22:03:58 +00:00

Handle disabled protocol instances.
1998-11-29 22:01:33 +00:00

ed45f2e126
Added functions for manipulating interface name pattern lists:
...
o iface_patt_match(list, iface) -- match interface against list
o iface_patts_equal(a, b, c) -- compare whether two pattern lists are
equal or not. c(x,y) is called for comparison of protocol-dependent
data.

Trivial 15-line bison excercise: Implemented expressions including

user-defined numeric symbols. Whenever possible, use `expr' instead
of `NUM' to get full express ion power :-)

Insert/remove hooks return void, not int.

a0762910a6
Added pointer to network to RTE. The complications with passing NET separately
...
aren't worth 4 bytes per RTE.
rte_discard and rte_dump don't need net * as parameter.
1998-10-20 15:13:18 +00:00
Martin Mares
7d83290780
Generate router_id automatically if possible (standard "smallest of local
...
regular interface addresses" rule).
Protocols should NOT rely on router_id existence -- when router ID is not
available, the router_id variable is set to zero and protocols requiring
valid router ID should just refuse to start, reporting such error to the log.
1998-10-19 18:13:36 +00:00

o FIB flags now available for FIB users.

o struct network: FIB flags used for kernel syncing.

After contemplating about RIP route timeouts for a long time, I've implemented
...
protocol callbacks for route insertion and deletion from the central table.
RIP should maintain its own per-protocol queue of existing routes, scan it
periodically and call rte_discard() for routes that have timed out.
1998-10-18 11:13:16 +00:00
Martin Mares

Implemented `route last modified' time.

Fixed misleading comment.

Each protocol now hears even its own routes and needs to make its own
...
loop detection. This is needed since both RIP and OSPF handle multiple
neighbors and they need to redistribute routes learned from each neighbor
to the remaining ones.
1998-10-17 11:24:13 +00:00

47b793064c
Solve chicken-and-egg problems with protocol startup. We now queue all inactive
...
protocols and don't send route/interface updates to them and when they come up,
we resend the whole route/interface tables privately.
Removed the "scan interface list after protocol start" work-around.
1998-10-17 11:05:18 +00:00

Route update hook now gets network prefix as well as updated

Dumping of _static_ attributes implemented.

Skeleton of device route protocol. As it's tightly coupled with our kernel,
...
it sits here instead of `proto/dev'.

Protocol hooks. All of them may be NULL.

- Rewrote whole interface logic. Removed support for multiple addresses per
...
interface since it makes much trouble everywhere. Instead, we understand
secondary addresses as subinterfaces.
- In case interface addresses or basic flags change, we simply convert it
to a down/up sequence.
- Implemented the universal neighbour cache. (Just forget what did previous
includes say of neighbour caching, this one is brand new.)

are OS-dependent).

Next attempt on data structures...
1998-05-03 16:42:45 +00:00
Martin Mares
1feea03e74
Changed #include <x/y> to #include "x/y" for our local includes, so that

gcc -MM can be used to separate them from the system ones.
Added automatic generation of dependencies.
1998-04-28 14:39:34 +00:00

Added IP address manipulation macros, interface declarations and logging.
1998-04-23 14:01:15 +00:00
