Chuck Lever d1208f7073 NLM: nlm_privileged_requester() doesn't recognize mapped loopback address ... Commit b85e4676 added the nlm_privileged_requester() helper to check whether an RPC request was sent from a local privileged caller. It recognizes IPv4 privileged callers (from "127.0.0.1"), and IPv6 privileged callers (from "::1"). However, IPV6_ADDR_LOOPBACK is not set for the mapped IPv4 loopback address (::ffff:7f00:0001), so the test breaks when the kernel's RPC service is IPv6-enabled but user space is calling via the IPv4 loopback address. This is actually the most common case for IPv6- enabled RPC services on Linux. Rewrite the IPv6 check to handle the mapped IPv4 loopback address as well as a normal IPv6 loopback address.
