ipv6: restrict IPV6_ADDRFORM operation 2020-03-18T06:19:20+00:00 Eric Dumazet edumazet@google.com 2020-02-25T19:52:29+00:00 8b871cdcbb11ed43c8268f89584e670b4cda7e12 commit b6f6118901d1e867ac9177bbff3b00b185bd4fdc upstream. IPV6_ADDRFORM is able to transform IPv6 socket to IPv4 one. While this operation sounds illogical, we have to support it.
