net: vrf: ipv6 support for local traffic to local addresses
Add support for locally originated traffic to VRF-local IPv6 addresses. Similar to IPv4 a local dst is set on the skb and the packet is reinserted with a call to netif_rx. With this patch, ping, tcp and udp packets to a local IPv6 address are successfully routed: $ ip addr show dev eth1 4: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master red state UP group default qlen 1000 link/ether 02:e0:f9:1c:b9:74 brd ff:ff:ff:ff:ff:ff inet 10.100.1.1/24 brd 10.100.1.255 scope global eth1 valid_lft forever preferred_lft forever inet6 2100:1::1/120 scope global valid_lft forever preferred_lft forever inet6 fe80::e0:f9ff:fe1c:b974/64 scope link valid_lft forever preferred_lft forever $ ping6 -c1 -I red 2100:1::1 ping6: Warning: source address might be selected on device other than red. PING 2100:1::1(2100:1::1) from 2100:1::1 red: 56 data bytes 64 bytes from 2100:1::1: icmp_seq=1 ttl=64 time=0.098 ms ip6_input is exported so the VRF driver can use it for the dst input function. The dst_alloc function for IPv4 defaults to setting the input and output functions; IPv6's does not. VRF does not need to duplicate the Rx path so just export the ipv6 input function.
