[lwip-devel] [bug #16390] Crash through adding and removing tcb's to the TIME_WAIT list

[anonymous]

Follow-up Comment #1, bug #16390 (project lwip):

Ok i did some more investigations...

the problem occured also at the active list.

And it occures if you write or read to/from connection if a further write or
read returns an error and is not handled. In my case it was a webserver
application. I wrote and wrote and wrote without checking for errors because
I thought the lower layers will handle it if there is a problem with writing
to a connection in a "wrong" state. The problem occured if the client is
resetting or closing the connection. The write give me an error and I didn't
handle it and continued writing. After this point the tcb lists get meshed
up.

I do error checking now and I am closing the connection if there is an error
and everything works fine.
