[lwip-devel] [bug #19162] lwip_sendto: possible to corrupt remote addr/port connection state

[Frédéric Bernon]

Follow-up Comment #19, bug #19162 (project lwip):

New patch file for the whole problem is attached. I'm not at the office this
week, so, I can't just build it, but not test it. So, befaore next week, see
it like a draft.

The idea is to directly call the "sendto" functions already available in raw
api (udp_sendto and raw_sendto). I just change netconn_send to replace a pbuf
by a netbuf (which contains field fromaddr & fromport). 

So, send any comments...

I have to check some details in raw api, but I think it can work just like
this...
