Hi,
Our device driver uses ip6 route output() and typecast the return value of dst_entry to rt6_info (similar to (net/ip6/icmp.c)
Driver uses (a) rt6i_dst.addr, (b) rt6i_dst.plen and (c) rt6i_gateway to get the route entry (ip/mask, gw, netdev).
Can anyone please confirm that drivers and/or netfilter kernel modules are allowed to use them?
Also ip_route_output_key() rtable and dst_entry doesn't seem to provide route entry's subnet mask/prefix value. how drivers/netfilter kernel module can get a ip/mask gateway value while given a destination IP address as input?
I really appreciate your inputs. I hope I am asking it on the relevant mailing list.
Regards,
Parav Pandit
