net: extend RTM_GETROUTE to return fib result
This series adds a new RTM_F_FIB_MATCH flag to return matched fib result
with RTM_GETROUTE. This is useful for applications and protocols in
userspace wanting to query the selected route.
examples (with patched iproute2):
ipv4:
----
$ip route show
default via 192.168.0.2 dev eth0
10.0.14.0/24
nexthop via 172.16.0.3 dev dummy0 weight 1
nexthop via 172.16.1.3 dev dummy1 weight 1
$ip route get 10.0.14.2
10.0.14.2 via 172.16.1.3 dev dummy1 src 172.16.1.1
cache
$ip route get fibmatch 10.0.14.2
10.0.14.0/24
nexthop via 172.16.0.3 dev dummy0 weight 1
nexthop via 172.16.1.3 dev dummy1 weight 1
ipv6:
----
$ip -6 route show
2001:db9:100::/120 metric 1024
nexthop via 2001:db8:2::2 dev dummy0 weight 1
nexthop via 2001:db8:12::2 dev dummy1 weight 1
$ip -6 route get 2001:db9:100::1
2001:db9:100::1 from :: via 2001:db8:12::2 dev dummy1 src 2001:db8:12::1 metric 1024 pref medium
$ip -6 route get fibmatch 2001:db9:100::1
2001:db9:100::/120 metric 1024
nexthop via 2001:db8:12::2 dev dummy1 weight 1
nexthop via 2001:db8:2::2 dev dummy0 weight 1
v2:
- pick up new forward port of patch-01 from david
- inet6_rtm_getroute: use container_of for rt6_info to
dst conversion

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
