Maria Matejka f18968f52f Better profylaction recursive route loops ... In some specific configurations, it was possible to send BIRD into an infinite loop of recursive next hop resolution. This was caused by route priority inversion. To prevent priority inversions affecting other next hops, we simply refuse to resolve any next hop if the best route for the matching prefix is recursive or any other route with the same preference is recursive. Next hop resolution doesn't change route priority, therefore it is perfectly OK to resolve BGP next hops e.g. by an OSPF route, yet if the same (or covering) prefix is also announced by iBGP, by retraction of the OSPF route we would get a possible priority inversion.		2021-11-22 19:05:43 +01:00
