[lwip-devel] [bug #19434] Processing of Fast retransmit bug

[Oleg Tyshev]

Follow-up Comment #2, bug #19434 (project lwip):

As I have wrote, "B" sends data very slow (transfer rate approx. 1
byte/sec).
So receive window of "A" will be closed in 4096/60 = 68 minutes.
You are right this is the bug of retransmission timeout - not fast
retransmit.
Fast retransmit has been once triggered and we can hope only on
retransmission timeout.

in tcp_slowtmr() we check pcb->rtime.
It is more then pcb->rto or not?
But in tcp_output_segment()
each time we set pcb->rtime = 0;

Unfortunately I can't generate ethereal log now.
Temporary I am switched to other target.
