[lwip-devel] [bug #20791] conn->recvmbox might be deleted twice in netconn_delete() and netconn_recv

[Frédéric Bernon]

Follow-up Comment #2, bug #20791 (project lwip):

More, lwIP is not safe-thread on one socket: you should not call with a Task
A netconn_delete, in the same time a Task B is "blocked" on a netconn_recv. In
a general way, you should not use two "application" tasks on a same
socket/netconn... You can find some informations/talks on :
