Follow-up Comment #2, bug #55987 (project lwip):
At the time of this bug submission, I was using Espressif esp-idf v3.2-beta3
https://github.com/espressif/esp-idf/releases/tag/v3.2-beta3
> LWIP related
> New Functionality
> Updated LWIP to v2.0.3 with Espressif patches
lwip_recvmsg calls lwip_recvfrom with NULL, NULL ...
https://github.com/espressif/esp-lwip/blob/e2a24de6603c896a5ddacac296c0304002376eae/src/api/sockets.c#L1284
ssize_t recvd_local = lwip_recvfrom(s, message->msg_iov[i].iov_base,
message->msg_iov[i].iov_len, recv_flags, NULL, NULL);
... even though it was given msghdr->msg_name{,len}
