2015-01-18server: make sure peer always read from acceptedConnChFUJITA Tomonori
When acceptedConnCh is full, the server goroutine will be blocked. It's not good even eventually the goroutine will run. This situation happens only with buggy bgp speaerk peers. But let's avoid this anyway. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
2015-01-18server: fix 'deleted config' raceFUJITA Tomonori
When a config is deleted, goroutine for FSMHandler.h.Dying becomes active. sendMessageloop must send notifcation before dying. So it should not check Dying(). After sending notificaiton, it closes the conneciton and return. It makes sure that rx goroutine will die too. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
2015-01-18server: support idlehold time after resetFUJITA Tomonori
After resetting a peer, the peer will remain idle for idlehold time (by default 30 seconds). It can be configured via IdleHoldTImeAfterReset. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
2015-01-18server: move outgoing and incoming channels to FSMHandlerFUJITA Tomonori
This patch solves the problem that old messages in outgoing will be sent in a new established session. Peer goroutine puts some messagages in the outgoing channel. Then the state changes from established. In such case, once the state becomes established, the "stale" messages in the outgoing channel will be sent. With this patch, new outgoing and incoming channels are created at every state change. No more "stale" messages in the channles. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

2015-01-04table: remove Path's source versionFUJITA Tomonori
Even if a connection with peer is down and up, table code gets BGPmessages belonging the first connection before the event of the peer down in order. So we don't need source version stuff inherent from Ryu BGP code. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
