5b208e296f Removing (struct rta)->cast. Never used. 2016-12-22 13:09:59 +01:00

4e276a8920 Merged multipath and single-path data structures. 
Dropped struct mpnh and mpnh_*()
Now struct nexthop exists, nexthop_*(), and also included struct nexthop
into struct rta.

Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed
to distinguish between these two cases, RTD_DEVICE is equivalent to
IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw).

From now on, we also explicitely want C99 compatible compiler. We assume
that this 20-year norm should be known almost everywhere.

7152e5efbb Build system reworked to one global Makefile with includes and no nesting 
Also removed the lib-dir merging with sysdep. Updated #include's
accordingly.

Fixed make doc on recent Debian together with moving generated doc into
objdir.

Moved Makefile.in into root dir

Retired all.o and birdlib.a
Linking the final binaries directly from all the .o files.

e86cfd41d9 KRT: Fix route learn scan when route changed 
When a kernel route changed, function krt_learn_scan() noticed that and
replaced the route in internal kernel FIB, but after that, function
krt_learn_prune() failed to propagate the new route to the nest, because
it confused the new route with the (removed) old best route and decided
that the best route did not changed.

Wow, the original code (and the bug) is almost 17 years old.

d7661fbe9d Removed BITS_PER_IP_ADDRESS, MAX_PREFIX_LENGTH, BIRD_AF 
Explicit setting of AF_INET(6|) in IP socket creation. BFD set to listen
on v6, without setting the V6ONLY flag to catch both v4 and v6 traffic.

9ddbfbddf8 Netlink: Allow more than 256 routing tables. 
Since 2.6.19, the netlink API defines RTA_TABLE routing attribute to
allow 32-bit routing table IDs. Using this attribute to index routing
tables at Linux, instead of 8-bit rtm_table field.

094d2bdb79 Implements ADD-PATH extension for BGP. 
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

krt_if_copy_params -> kif_sys_copy_config
krt_set/scan_params_same -> krt_sys_reconfigure
krt_set/scan_copy_params -> krt_sys_copy_config
