Hi, Playing around with IPv6 tokens, I ran into a problem: Once you have a token set on an interface, it's impossible to remove it!
# ip token set :: dev eth0 RTNETLINK answers: Invalid argument This is a side-effect of rejecting ipv6_addr_any in inet6_set_iftoken. While this gets fixed, I have two related feature requests for this: - Please make it possible to configure multiple tokens on an interface: Use case: Deploying local services on well-known addresses inside a network without explicit prefix configuration. - Adding a token causes other address generation methods to be disabled, this is problematic if you wish to prefer privacy addresses for outbound connections. Design suggestion: Convert from using a single token to using a list of tokens, with an explicit default IPv6-any-addr (::) in the list, to represent that other address generation should ALSO take place (EUI64/privacy). Deletion of the any-addr from the list should disable EUI64/privacy addresses. -- Robin Hugh Johnson Gentoo Linux: Developer, Infrastructure Lead, Foundation Trustee E-Mail : robb...@gentoo.org GnuPG FP : 11ACBA4F 4778E3F6 E4EDF38E B27B944E 34884E85
