Yes, this is correct and has been since for all the lwIP history (at least what's in CVS)! > I have old code that appears to refute that. > > I have a project using FreeRTOS and what appears to be lwIP v1.1.

You're lucky there! lwIP includes lists that are sometimes re-sorted which can end up in system crash when used simultaneously from different threads! I strongly suggest you'd fix your code, no matter if you upgrade to 1.3.1 or stay with 1.1.0. To do that, you can just use tcpip_callback() to get your code running in the tcpip_thread context, where you can safely call udp_send().
