[PATCH 0/2] IPv4-mapped on wire, :: dst address issue

Under some circumstances IPv6 datagrams are sent with IPv4-mapped IPv6 addresses as the source. Given an IPv6 socket bound to an IPv4-mapped IPv6 address, and an IPv6 destination address, both TCP and UDP will will send packets using the IPv4-mapped IPv6 address as the source. Per RFC 6890 (Table

[PATCH 1/2] ipv6: Inhibit IPv4-mapped src address on the wire.

This patch adds a check for the problematic case of an IPv4-mapped IPv6 source address and a destination address that is neither an IPv4-mapped IPv6 address nor in6addr_any, and returns an appropriate error. The check in done before returning from looking up the route. Signed-off-by: Jonathan T.

[PATCH 2/2] ipv6: Handle IPv4-mapped src to in6addr_any dst.

This patch adds a check on the type of the source address for the case where the destination address is in6addr_any. If the source is an IPv4-mapped IPv6 source address, the destination is changed to :::127.0.0.1, and otherwise the destination is changed to ::1. This is done in three locations
