H A D | icmp.c | 24b711ed Thu Jul 19 14:41:18 CDT 2018 David Ahern <dsahern@gmail.com> net/ipv6: Fix linklocal to global address with VRF
Example setup: host: ip -6 addr add dev eth1 2001:db8:104::4 where eth1 is enslaved to a VRF
switch: ip -6 ro add 2001:db8:104::4/128 dev br1 where br1 only has an LLA
ping6 2001:db8:104::4 ssh 2001:db8:104::4
(NOTE: UDP works fine if the PKTINFO has the address set to the global address and ifindex is set to the index of eth1 with a destination an LLA).
For ICMP, icmp6_iif needs to be updated to check if skb->dev is an L3 master. If it is then return the ifindex from rt6i_idev similar to what is done for loopback.
For TCP, restore the original tcp_v6_iif definition which is needed in most places and add a new tcp_v6_iif_l3_slave that considers the l3_slave variability. This latter check is only needed for socket lookups.
