[lwip-devel] [bug #50837] TCP: zero window probe doesn't timeout

[Simon Goldschmidt]

Follow-up Comment #27, bug #50837 (project lwip):

Joel, sorry for taking so long again.

Technically, the patch seems to do what we need. I'm not happy with adding yet
another counter though. Our TCP keeps growing lately :-( (even if this doesn't
influence RAM in this special case).

This and the fact that TCP_MAXRTX leads to a different timeout for the persist
phase (backoff timeouts are different) makes me think we should rather have a
connection timeout expressed in seconds, but I don't know if that's OK with
the RFCs...

Maybe it's best for now to push your patch.
