monitor: Simplify event throttling
The event throttling state machine is hard to understand. I'm not
sure it's entirely correct. Rewrite it in a more straightforward
manner:
State 1: No event sent recently (less than evconf->rate ns ago)
Invariant: evstate->timer is not pending, evstate->qdict is null
On event: send event, arm timer, goto state 2
State 2: Event sent recently, no additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is null
On event: store it in evstate->qdict, goto state 3
On timer: goto state 1
State 3: Event sent recently, additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is non-null
On event: store it in evstate->qdict, goto state 3
On timer: send evstate->qdict, clear evstate->qdict,
arm timer, goto state 2

filter-rewriter: rewrite tcp packet to keep secondary connection
We will rewrite tcp packet secondary received and sent.
When colo guest is a tcp server.
Firstly, client start a tcp handshake. the packet's seq=client_seq,
ack=0,flag=SYN. COLO primary guest get this pkt and mirror(filter-mirror)
to secondary guest, secondary get it use filter-redirector.
Then,primary guest response pkt
(seq=primary_seq,ack=client_seq+1,flag=ACK|SYN).
secondary guest response pkt
(seq=secondary_seq,ack=client_seq+1,flag=ACK|SYN).
In here,we use filter-rewriter save the secondary_seq to it's tcp connection.
Finally handshake,client send pkt
(seq=client_seq+1,ack=primary_seq+1,flag=ACK).
Here,filter-rewriter can get primary_seq, and rewrite ack from primary_seq+1
to secondary_seq+1, recalculate checksum. So the secondary tcp connection
kept good.
When we send/recv packet.
client send pkt(seq=client_seq+1+data_len,ack=primary_seq+1,flag=ACK|PSH).
filter-rewriter rewrite ack and send to secondary guest.
primary guest response pkt
(seq=primary_seq+1,ack=client_seq+1+data_len,flag=ACK)
secondary guest response pkt
(seq=secondary_seq+1,ack=client_seq+1+data_len,flag=ACK)
we rewrite secondary guest seq from secondary_seq+1 to primary_seq+1.
So tcp connection kept good.
In code We use offset( = secondary_seq - primary_seq )
to rewrite seq or ack.
handle_primary_tcp_pkt: tcp_pkt->th_ack += offset;
handle_secondary_tcp_pkt: tcp_pkt->th_seq -= offset;
