New Patches Allow Building Linux IPv6-Only, Option To Deprecate "Legacy" IPv4
Summary
Phoronix reports on patch series by David Woodhouse to deprecate legacy IP in the Linux kernel, enabling IPv6-only builds with a CONFIG_LEGACY_IP option and warnings for legacy sockets. The discussion includes intent to move toward IPv6-first networking while possibly maintaining IPv4 support in some contexts; the patches are hosted on the kernel mailing list and tied to April Fools Day context but show real engineering merit.
