Multiple changes by Ondrej Santiago Zajicek
Removed BITS_PER_IP_ADDRESS, MAX_PREFIX_LENGTH, BIRD_AF
Explicit setting of AF_INET(6|) in IP socket creation. BFD set to listenon v6, without setting the V6ONLY flag to catch both v4 and v6 traffic.

Nest: Fixes bug in missing cleanup during table removal
When a table is removed during reconfiguration, a reference was notcleared in the old configuration, which breaks undo.
Conf: Fixes bug in symbol lookup during reconfiguration
Symbol lookup by cf_find_symbol() not only did the lookup but also addednew void symbols allocated from cfg_mem linpool, which gets broken whenlookups are done outside of config parsing, which may lead to crashes...
Initial commit on integrated BIRD
New data types net_addr and variants (in lib/net.h) describingnetwork addresses (prefix/pxlen). Modifications of FIB structuresto handle these data types and changing everything to use thesedata types instead of prefix/pxlen pairs where possible....
Major RIP redesign
The new RIP implementation fixes plenty of old bugs and also adds supportfor many new features: ECMP support, link state support, BFD support,configurable split horizon and more. Most options are now per-interface.
BGP multipath support
Kernel option 'merge paths' allows to merge routes exported to kernelprotocol (currently BGP and static routes) to multipath routes.
Fixes subtle bug in temporary attribute handling
In some cases, export filter accessed attributes of a different route.
Fixes bug in pipe feeding when filtered routes are kept in table
unsigned [int] -> uint
Simplify flushing process
Related to changes from previous patch.
Fix minor issue in pipe route propagation
In some circumstances during reconfiguration, routes propagated by pipesto other tables may hang there even after the primary routes are removed.
There is already a workaround for this issue in the code which removes...
Allows user data attached to f_trie_node structure.
Thanks to Alexander Chernikov for the patch.
Fixes error message in 'show route' cmd.
Message 'Network not in table' was not reported if a network node withoutany routes was found in a routing table.
Implements show route noexport option.
Shows routes that would be exported to the protocol but are rejected bythe export filter.
Implements token bucket filter for rate limiting.
Fixes 'show route export' w.r.t. protocols with different RA_* types.
Documentation (and minor fixes) for BGP graceful restart.
BGP graceful restart support.
Also significant core protocol state changes needed for that,global graceful restart recovery state and kernel proto supportfor recovery.
Merge branch 'master' into add-path
filter/filter.c nest/proto.c nest/rt-table.c proto/bgp/bgp.h proto/bgp/config.Y
Adds rate limiting to some log messages.
Fixes bug in protocol flushing and rtable pruning.
When route was propagated to another rtable through a pipe and then thepipe was reconfigured softly in such a way that any subsequent routeupdates are filtered, then the source protocol shutdown didn't clean up...
Fixes problems with kernel routes multiple routing tables.
Temporary dummy routes created by a kernel protocol during routing tablescan get mixed with real routes propagated from another kernel protocolthrough a pipe.
Default rounting table for 'show route export/preexport/protocol' is the one related to a respective protocol.
Implements router advertisements activated by received routes.
The RAdv protocol could be configured to change its behavior based onavailability of routes, e.g., do not announce router lifetime when adefault route is not available.
Separate import and receive limits.
They have different behavior w.r.t. filtered routes that are kept.
Fixes route tracing w.r.t. kept filtered routes.
Changes 'rejected' to 'filtered' in one of the last patches.
Allows rejected routes to be kept and examined.
When 'import keep rejected' protocol option is activated, routesrejected by the import filter are kept in the routing table, but theyare hidden and not propagated to other protocols. It is possible toexamine them using 'show route rejected'.
Implements ADD-PATH extension for BGP.
Allows to send and receive multiple routes for one network by one BGPsession. Also contains necessary core changes to support this (routingtables accepting several routes for one network from one protocol).It needs some more cleanup before merging to the master branch.
Allows to redefine master table.
Merge branch 'rt-accepted'
nest/config.Y nest/rt-table.c proto/bgp/bgp.c
Finalize RA_ACCEPTED handling.
Fixes a bug in RA_ACCEPTED handling.
Some fixes in route export limits.
Some minor fixes.
Implements generalized export limits.
And also fixes some minor bugs in limits.
Fixes in generalized import limits.
Implements generalized import hooks.
Thanks to Alexander V. Chernikov for the original patch.
Implement RA_ACCEPTED mode of route propagation.
Merge branch 'soon'
Fixes responsiveness for protocol shutdown.
When a protocol went down, all its routes were flushed in one step, thatmay block BIRD for too much time. The patch fixes that by limitingmaximum number of routes flushed in one step.
Better support for multitable protocols.
The nest-protocol interaction is changed to better handle multitableprotocols. Multitable protocols now declare that by 'multitable' field,which tells nest that a protocol handles things related to proto-rtableinteraction (table locking, announce hook adding, reconfiguration of...
Implements deterministic MED handling.
Thanks to Alexander V. Chernikov for many suggestions.
Signal problems with route installation to kernel tables.
Fixes a bug with setting preference during show route cmd.
If show route cmd was used with a filter that changed preference,BIRD crashed.
Compilation was failing without OSPF or RIP protocol - FIXED.
Fixes a nasty bug in OSPF.
Sending malformed network prefixes in LSAs causes OSPF to crashjust after the LSA is propagated to the other routers.
Core multipath support.
Fixes a one byte buffer overflow.
Do not allow interdependent recursive routes.
Adds igp_metric attribute.
Implements IGP metric comparison for BGP routes.
Use link-local addresses in recursive next hops for IPv6 BGP.
Hostcache should use trie to filter relevant route changes.
For hostentry cache, replace FIB with a hash table using (IP, dep table) as a key.
Fixes a buffer overflow in TX code of IPv6 BGP.
Implements hostcache and recursive next hops.
Hostcache is a structure for monitoring changes in a routing table thatis used for routes with dynamic/recursive next hops. This is needed forproper iBGP next hop handling.
Implements command that shows memory usage.
Restrict export of device routes to the kernel protocol.
In usual configuration, such export is already restrictedwith the aid of the direct protocol but there are someraces that can circumvent it. This makes it harder tobreak kernel device routes. Also adds an option to...
Update lastmod in 'ignored' case only for RIP routes.
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...
Fix configure to enable warnings and fix most of them.
Removes phantom protocol from the pipe design.
It seems that by adding one pipe-specific exception to routeannouncement code and by adding one argument to rt_notify() callback icould completely eliminate the need for the phantom protocol instanceand therefore make the code more straightforward. It will also fix some...
Fixes protocol statistics for pipes.
Fixes a tricky bug in the pipe protocol.
When uncofiguring the pipe and the peer table, the peer table wasunlocked when pipe protocol state changed to down/flushing and not todown/hungry. This leads to the removal of the peer table beforethe routes from the pipe were flushed....
Adds asterisk to the primary route in 'show route' cmd.
And also fixes a minor bug.
Makes date/time formats configurable.
Finishes 'route reload' feature.
Implements route re-feed.
This can be used to re-feed routes to protocol after soft change inexport filters.
Fixes some problems in pipes.
For transparent pipes, loop detection works correctly now.Pipes are now more symmetric - in both directions filteringis done in do_rte_announce().
Fixes one missing log message.
Implements BGP route refresh.
Fixes serious bug in core related to route filtering.
If protocol announces a route, route is accepted by import filter torouting table, and later it announces replacement of that route that isrejected by import filter, old route remains in routing table.
Fixes another bug in rte_recalculate().
Previous bugfix revealed another hidden bug here.
Fixes bug that caused losing of some routes.
When update changes preferred route in such a way thatit ceased to be preferred, the new route was linkedto wrong place and lost.
Implements route statistics and fixes some minor bugs.
Escaped debbuging message removed.
The pipe cleanup.
Changes pipes to transfer all routes between routing table, not just optimal routes.
Change import/preimport to export/preexport to be consistent with filters.
'show route protocol <p>' added to CLI.
Fixes bug in pipe route filtering.
Routes comming through pipe from primary to secondary table werefiltered by both EXPORT and IMPORT filters, but they should beonly filtered by EXPORT filters.
Fixes feeding of new protocol, only preferred routes are announced.
Grrr, committing too fast.#include "alloca.h" -> #include "lib/alloca.h"
Use #include "alloca.h"
protocol->import_control() could potentially call rte_cow() as well.AFAIK it doesn't happen in any of our protocol, but better be sure.
This was a potential memory leak, but not the one Feela observed.
This one could happen when an import filter of some protocol modifiedthe rte (so that it would be rte_cow()ed) and later rejected it.
Added missing includes.
Fix %<something>I format strings.
Fixes for the programmer's manual.
Fixes to the progdoc.
Spelling fixes to progdoc.
Better description of the route distribution process.
Documentation on routing tables and route attributes.
