[lwip-devel] [bug #50837] LWIP TCP/IP race condition

[Joel Cunningham]

Follow-up Comment #22, bug #50837 (project lwip):

Preet,

The mailbox implementation is port specific.  My port uses static memory to
provide storage for the mbox messages, sounds like your uses LwIP's memory
pool

All that aside, I think we have a problem with a connection stuck in zero
window probing.  

Simon,

I spent more time examining the source and for a socket using blocking sockets
(not using SO_SNDTIMEO) I can't find anything that would time out the
connection.  If I've missed something, please point me in the direction that
contains the timeout

If I get some more time, I might put together a unit test.  We should be able
to reasonably test connection failures for both retransmission timeouts and
zero window probes
