* Added test for sEstablished before processing incoming updates.Chris Hall2010-02-032-4/+54
| | | | | | | | | | | | | | Before disabling a session the Peering Engine now revokes its inbound queue for the session. This clears out anything that may have been queued up to that moment for the session. After disabling a session, some updates may still arrive, because it may be a while before the BGP Engine actions the disable, and stops queueing stuff. So, Peering Engine must check that the session is established before processing stuff in the queue. modified: bgpd/bgp_engine.h modified: bgpd/bgp_session.c

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wired up message counters in bgp_session structure. Added fields to session for neighbor interface and neighbor update-source -- so that these can be set when connect() is done. Peering Engine resolves any interface name to an address, so that BGP Engine doesn't have to. Reinstated as much code as necessary in bgp_network to bind to specific interfaces, as set in the session. Moved setting of bgp_nexthop_set() back into Routeing Engine. Result is that only Peering Engine talks to Zebra or uses the iflist. Wired up setting of TTL. Reworked connections locking of the session mutex so more robust if/when connections are cut loose from the session. Made peer_index entry point at connection, not session. Works better in bgp_network that way. modified: bgpd/bgp_connection.c modified: bgpd/bgp_connection.h modified: bgpd/bgp_fsm.c modified: bgpd/bgp_msg_read.c modified: bgpd/bgp_msg_write.c modified: bgpd/bgp_network.c modified: bgpd/bgp_network.h modified: bgpd/bgp_peer.c modified: bgpd/bgp_peer.h modified: bgpd/bgp_peer_index.c modified: bgpd/bgp_peer_index.h modified: bgpd/bgp_session.c modified: bgpd/bgp_session.h modified: lib/prefix.h modified: lib/sockunion.c modified: lib/sockunion.h

Added BGP Id check to collision detection logic. Removed as many warnings from comilation as possible. Replaced horrible FIFO kludge in the process.

* Blitz on bgp_msg_read, particularly OPEN message handlingChris Hall2010-01-2321-899/+1532
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the BGP Engine the OPEN message needs to be processed into the open_recv structure in the *connection*. The OPEN that arrives must be checked for acceptability before it is acknowledged. Later the connection may be discarded in collision resolution, or the connection may become the Established connection, and the open_recv structure is passed to the session and hence to the Peering Engine. modified: bgpd/bgp.h modified: bgpd/bgp_common.c modified: bgpd/bgp_common.h modified: bgpd/bgp_connection.c modified: bgpd/bgp_connection.h modified: bgpd/bgp_fsm.c modified: bgpd/bgp_msg_read.c modified: bgpd/bgp_msg_read.h modified: bgpd/bgp_msg_write.c modified: bgpd/bgp_notification.c modified: bgpd/bgp_notification.h modified: bgpd/bgp_open.h modified: bgpd/bgp_open_state.c modified: bgpd/bgp_open_state.h modified: bgpd/bgp_packet.c modified: bgpd/bgp_session.h modified: lib/distribute.c modified: lib/if_rmap.c modified: lib/qafi_safi.h modified: lib/stream.c modified: lib/stream.h
