This series adds a new test to test fib rules.
ip route get is used to test fib rule matches.
This series also extends ip route get to match on
sport and dport to test recent support of sport
and dport fib rule match.
v2 - address ido's commemt to make sport dport
ip route get to work correctly for input route
get. I don't support ip route get on ip-proto match yet.
ip route get creates a udp packet and i have left
it at that. We could extend ip route get to support
a few ip proto matches in followup patches.
v3 - Support ip_proto (only tcp and udp) match in getroute.
dropped printing of new match attrs in ip route get,
because ipv6 does not print it. And ipv6 currrently shares
the dump api with ipv6 notify and its better to not add them
to the notify api. dropped it to keep the api consistent between
ipv4 and ipv6 (though uid is already printed in the ipv4 case).
If we need it, both ipv4 and ipv6 can be enhanced to provide
a separate get api. Moved skb creation for ipv4 to a separate func.
v4 - drop separate skb for netlink and fix concerns around rcu and netlink
reply (as pointed out by DaveM). I now try to reset the skb after the route
lookup and before the netlink send (testing shows this is ok. More eyes and
any feedback here will be helpful)
v5 - dropped RTA_TABLE ipv4_rtm_policy update from this series and posted
it separately for net (feedback from Eric)
Roopa Prabhu (3):
ipv4: support sport, dport and ip_proto in RTM_GETROUTE
ipv6: support sport, dport and ip_proto in RTM_GETROUTE
