      selftests: fib_tests: Add ipv4 route add append replace tests · abb1860a
      由 David Ahern 提交于 
      Add IPv4 route tests covering add, append and replace permutations.
Assumes the ability to add a basic single path route works; this is
required for example when adding an address to an interface.

      由 David Ahern 提交于 
      Add option to pause after each test before cleanup is done. Allows
user to do manual inspection or more ad-hoc testing after each test
with the setup in tact.

      Add command line options for controlling pause on fail, controlling
specific tests to run and verbose mode rather than relying on environment

      net/ipv6: Simplify route replace and appending into multipath route · f34436a4
      由 David Ahern 提交于 
      Bring consistency to ipv6 route replace and append semantics.

Remove rt6_qualify_for_ecmp which is just guess work. It fails in 2 cases:
1. can not replace a route with a reject route. Existing code appends
   a new route instead of replacing the existing one.

2. can not have a multipath route where a leg uses a dev only nexthop

Existing use cases affected by this change:
1. adding a route with existing prefix and metric using NLM_F_CREATE
   without NLM_F_APPEND or NLM_F_EXCL (ie., what iproute2 calls
   'prepend'). Existing code auto-determines that the new nexthop can
   be appended to an existing route to create a multipath route. This
   change breaks that by requiring the APPEND flag for the new route
   to be added to an existing one. Instead the prepend just adds another
   route entry.

2. route replace. Existing code replaces first matching multipath route
   if new route is multipath capable and fallback to first matching
   non-ECMP route (reject or dev only route) in case one isn't available.
   New behavior replaces first matching route. (Thanks to Ido for spotting
   this one)

Note: Newer iproute2 is needed to display multipath routes with a dev-only
      nexthop. This is due to a bug in iproute2 and parsing nexthops.
