I'm having some trouble understanding what the thread-safety requirements for using LWIP are. I've been through the archives on the LWIP mailing lists where it's explicitly stated that the low-level APIs are not thread-safe, but I can't find an equivalent description of the high-level socket interfaces. It appears to depend on how the specific OS port was done. The reason I'm looking at this is because I'm getting the following assertion failure:
ASSERT FAIL: <6>pbuf.c[577]pbuf_free() pbuf_free: p->ref > 0 According to the LWIP archives this assertion is often evidence of a violation of the stack's thread-safety rules. I'm exclusively using the socket APIs from a single thread, so I'm wondering whether I need to take any additional steps to satisfy these requirements. Can someone with a better understanding of the eCos LWIP port comment? On the other hand, I'm running with a rather miserly buffer allocation, and I suppose it's possible that I'm tickling some other bug in the pbuf code. Any thoughts and suggestions are very appreciated.
