[New-bugs-announce] [issue23176] socket.recvfrom(0) waits for data

[Sworddragon]

New submission from Sworddragon:

For example on sending ICMP packets and receiving the data socket.recv(1) does wait for data while socket.recv(0) doesn't. socket.recvfrom(1) does wait for data too but I'm also seeing that socket.recvfrom(0) is waiting for data which doesn't look correct (at least it seems not to be consistent with socket.recv()).
