[lwip-devel] [bug #19167] tcp timeout handler can cause crash being invoked by sys_sem_wait()

[Simon Goldschmidt]

Update of bug #19167 (project lwip):

                  Status:                    None => In Progress            
             Assigned to:                    None => goldsimon

Follow-up Comment #17:

If the other developers don't mind, I'll take a look at this. I think
lwip-users summarized it to taking timers (aka timeouts) off the semaphores,
so that timeouts only can occur when waiting for an mbox.
This behaviour would be good with me.

Although it's no problem for me (I don't use semaphores in tcpip_thread
context since I don't use a heap and I have SYS_LIGHTWEIGHT_PROT=1), I would
like to see this fixed and think the current implementation is bad behaviour.
