Follow-up Comment #2, bug #24440 (project lwip):
> there's no need for an accept callback entry on a struct tcp_pcb
I'm afraid there is: when a new connection is opened by a listening pcb, the
accept pointer is copied to the new tcp_pcb. The reason is the callback is
only called after the ACK for the SYN is received from the remote host.
> tcp_accept() should take a struct tcp_pcb_listen type
But we need to reset the accept pointer for a normal pcb, too. I guess a
better fix would be to move accept into TCP_PCB_COMMON so that it is the same
for both tcp pcb types.
An even better fix would be to change the *_PCB_COMMON/IP_PCB defines to
aggregating other structs so that we are safe from compilers that change the
layout of structs, but that could well be another discussion...
