Alexander V. Chernikov 36402a681f Finish r275196: do not dereference rtentry in if_output() routines. ... The only piece of information that is required is rt_flags subset. In particular, if_loop() requires RTF_REJECT and RTF_BLACKHOLE flags to check if this particular mbuf needs to be dropped (and what error should be returned). Note that if_loop() will always return EHOSTUNREACH for "reject" routes regardless of RTF_HOST flag existence. This is due to upcoming routing changes where RTF_HOST value won't be available as lookup result. All other functions require RTF_GATEWAY flag to check if they need to return EHOSTUNREACH instead of EHOSTDOWN error. There are 11 places where non-zero 'struct route' is passed to if_output(). For most of the callers (forwarding, bpf, arp) does not care about exact error value. In fact, the only place where this result is propagated is ip_output(). (ip6_output() passes NULL route to nd6_output_ifp()). Given that, add 3 new 'struct route' flags (RT_REJECT, RT_BLACKHOLE and RT_IS_GW) and inline function (rt_update_ro_flags()) to copy necessary rte flags to ro_flags. Call this function in ip_output() after looking up/ verifying rte. Reviewed by: ae		2016-01-09 16:34:37 +00:00
