36bbfc704c Updated filters: they now actually see IP/pxlen of net being filtered,
gateway, and who told us, so they can do usefull jobs from now on.

4c5e5e3a1c Multicasts once again: When using SO_BINDTODEVICE, don't specify IP address
of the interface.

1b50a1e4be Next attempt to get SO_BINDTODEVICE work :) 1999-04-14 11:39:07 +00:00
Martin Mares
36154beb70 Use SO_BINDTODEVICE if we're using old multicast API (i.e., struct ip_mreq
and not ip_mreqn). This should get multicasts on unnumbered PtP links work.

9da4d14340 A couple of OSPF fixes:
o  ((flags & IF_CHANGE_UP) == IF_CHANGE_UP)   ->   (flags & IF_CHANGE_UP)
o  bcopy  ->  memcpy   (bcopy is unportable)
o  Ifdeffed out add_tail(&(ifa->sk_list),NODE mcsk) -- the node in socket
   structure is for internal use by the resource manager only. (Now, the
   debugging dump of open sockets looks sane :-)).

43fc099b98 Sets of IP addresses should work, now. (From now on it is also
possible to write if 1.2.3.4 < 1.2.3.5, but I'm not sure if it is good
for anything.)

620c4f90c9 Oops, a typo in previous struct ip_mreqn changes... 1999-04-12 17:20:50 +00:00
Martin Mares
61fb537c62 Use struct ip_mreqn' instead of struct ip_mreq' for multicast
operations on 2.1/2.2 kernels. This allows passing of real interface
indexes instead of referencing interfaces by their IP addresses which
fails badly in presence of unnumbered interfaces.

Unfortunately, this structure is not visible with glibc 2.0 as it provides
its own networking headers :-(  Both libc5 and glibc 2.1 should be OK.

Also made "depend" work before the tree is compiled first time.

23b1539bf9 Filters upgraded - a bit. Moved code to filter.c because it is where
it belongs. (f-util.c stays there for auxiliary and non-important things.)

e2dc2f30ef Routing table core changes to support full route filtering:
o  Introduced rte_cow() which should be used for copying on write the
   rte's in filters. Each rte now carries a flag saying whether it's
   a real route (possessing table linkage and other insignia) or a local
   copy. This function can be expected to be fast since its fast-path
   is inlined.
o  Introduced rte_update_pool which is a linear memory pool used for
   all temporary data during rte_update. You should not reference it directly
   -- instead use a pool pointer passed to all related functions.
o  Split rte_update to three functions:

	rte_update	The front end: handles all checking, inbound
			filtering and calls rte_recalculate() for the
			final version of the route.
	rte_recalculate	Update the table according to already filtered route.
	rte_announce	Announce routing table changes to all protocols,
			passing them through export filters and so on.

   The interface has _not_ changed -- still call rte_update() and it will
   do the rest for you automagically.
o  Use new filtering semantics to be explained in a separate mail.

9e0e485e50 Added some new protocol hooks (look at the comments for better explanation):
make_tmp_attrs		Convert inline attributes to ea_list
	store_tmp_attrs		Convert ea_list to inline attributes
	import_control		Pre-import decisions

5056c559c4 Changed syntax of attaching filters to protocols to hopefully the final
version:

	EXPORT <filter-spec>	for outbound routes (i.e., those announced
				by BIRD to the rest of the world).
	IMPORT <filter-spec>	for inbound routes (i.e., those imported
				by BIRD from the rest of the world).

where <filter-spec> is one of:

	ALL			pass all routes
	NONE			drop all routes
	FILTER <name>		use named filter
	FILTER { <filter> }	use explicitly defined filter

For all protocols, the default is IMPORT ALL, EXPORT NONE. This includes
the kernel protocol, so that you need to add EXPORT ALL to get the previous
configuration of kernel syncer (as usually, see doc/bird.conf.example for
a bird.conf example :)).

63a381dbf5 Several filter changes. (Pavel, please check if they are OK.)
o  Changed parameters of f_run. Changed rtein+rteout pair to rte pointer
      passed by reference, added ea_list of temporary attrs again passed
      by reference and finally added a pointer to memory pool for storing
      temporary data (new ea_lists's, temporary rta's etc.).
   o  Re-ordered result codes, so that all accepts come before all rejects.
   o  Introduced FILTER_ACCEPT and FILTER_REJECT dummy values (will be
      used in protocol configurations).
   o  Added filter_name() which returns name of a filter or ACCEPT/REJECT
      for the dummies.

d4ff748224 Use a more reasonable pool chunk size: 4080 bytes seem to be a good
approximation of a integral fraction of page size even if both malloc
overhead and chunk header space is counted.

c10421d3d4 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
   the ones the kernel really uses for forwarding packets.
o  Better treatment of CONFIG_AUTO_ROUTES ports.
o  Lots of internal changes.

69ec9087ad Added new protocol hook for dumping of protocol-dependent route
attributes.

Please implement in all protocols.

73c7bed168 Defined CONFIG_SELF_CONSCIOUS whenever the kernel scanner is able
to distinguish between our own routes and alien ones.
