parentipv6: add a wrapper for ip6_dst_store() with flowi6 checks (diff)
ipv6: allow to cache dst for a connected sk in ip6_sk_dst_lookup_flow()
Add 'connected' parameter to ip6_sk_dst_lookup_flow() and update the cache only if ip6_sk_dst_check() returns NULL and a socket is connected. The function is used as before, the new behavior for UDP sockets in udpv6_sendmsg() will be enabled in the next patch.
