Hi.
Thank you for the report. I don't know what could be the reason. I tested on big endian linux (powerpc) and it works without problems (same configuration in stack_config.h). Also I can see no problem in the socket code. It is a strange behavior of the recv function in your case. As you recognized there had been some changes in the past. The socket handling had been changed to non-blocking in order to allow multiple connections handled in the same thread.

Hi.
You must be very busy to maintain such a large project. Thank you for taking time out of your busy schedule to verify my questions.
I thought later that this problem might be on our side. Because we have made some customization of kernel parameters, and even overwrote some packet-receiving drivers. Maybe there's a potential problem.
I personally spent a lot of time debugging this problem. My original intention here was to find out what was wrong immediately when I met someone else who had the same problem as me.
Thanks.
