UDPv4 sockets don't return EAFNOSUPPORT when sending to IPv6 addresses

Open puradox opened this issue 4 years ago • 4 comments

Description

While refactoring a PacketImpact test for UDP sockets, I found a discrepancy with Linux.

When bound to an IPv4 address and sending to an IPv6 address, sendto returns EINVAL whereas Linux returns EAFNOSUPPORT.

Steps to reproduce

Run test //third_party/gvisor/test/packetimpact/tests:generic_dgram_socket_send_recv_test with the if statement linked to this bug removed.
