[lwip-devel] [bug #63938] On apprupt tcp interrupten the pcb->next list points to itself

[Sylvain Rochet]

Follow-up Comment #3, bug #63938 (project lwip):

Linked list corruption is the most common issue of contexts clash.

Please add support for LWIP_ASSERT_CORE_LOCKED (and LWIP_MARK_TCPIP_THREAD if
necessary) before anything else.

(As a side note, tcp_recved() is usually called from the TCP recv callback
and, as such, does not need locking).
