[lwip-devel] [bug #50498] tcp: do not keep sending SYNs when getting ACKs

[Simon Goldschmidt]

Follow-up Comment #1, bug #50498 (project lwip):

I'm OK with the change, but I don't see how the loop could be endless given
that 'tcp_rexmit_rto()' increases 'pcb->nrtx' and 'tcp_slowtmr()' checks for
TCP_SYNMAXRTX.

Wait, I see:
1) 'pcb->nrtx' can overflow if 'tcp_rexmit_rto()' is called too often and
2) 'tcp_slowtmr()' checks for '==' instead of '>='

We might want to fix these anyway since 'pcb->nrtx' is used as an offset into
the 'tcp_backoff' array...
