On receipt of a redirect message, install an interface route for the
redirected destination. On removal of the corresponding Neighbor Cache
entry, remove the interface route.
This requires changes in rtredirect_fib() to cope with an AF_LINK
address for the gateway and with the absence of RTF_GATEWAY.
This fixes the "Redirected On-Link" test cases in the Tahi IPv6 Ready Logo
Phase 2 test suite.
Unrelated to the above, fix a recursion on the radix node head lock
triggered by the Tahi Redirected to Alternate Router test cases.
When I first wrote this patch in October 2012, all Section 2
(Neighbor Discovery) test cases passed on 10-CURRENT, 9-STABLE,
and 8-STABLE. cem@ recently rebased the 10.x patch onto head and reported
that it passes Tahi. (Thanks!)
These other test cases also passed in 2012:
* the RTF_MODIFIED case, with IPv4 and IPv6 (using a
RTF_HOST|RTF_GATEWAY route for the destination)
* the redirected-to-self case, with IPv4 and IPv6
* a valid IPv4 redirect
All testing in 2012 was done with WITNESS and INVARIANTS.
