Hi Alexander, I share your feeling that it may be better to adopt the behavior of Linux and Android to stay on safe grounds. But on the other hand, I could not find any reference which states that recv() will return a complete TCP segment in all cases (only the opposite, e.g., [1]). Please correct me if I'm wrong. Therefore, any application relying on this fact would be broken. Regarding writev() to the local socket buffer most implementations also seems to gather all data from the iovec in one run. But, this is hidden from the receiver, which has to expect that the data was fragmented on any network layer including the syscall interface.
For these reasons, I suggest we leave the implementation as is for now.
