* don't cancel events on termination * Zebra dplane may call plugin termination functions more than once. Fix the methods so that they can be called multiple times without creating double-frees or use-after-free conditions. * Add methods to get list counts and free dplane ctx when shutting down. * Handle the fact that while terminating, zebra may attempt to delete routes. When zebra shuts down, the plugin will not delete any state in dataplane. This is intended as the expectation is that a new instance will be promptly spawn and dataplane will then handle any stale routes left by the leaving zebra instance after a while. If this behavior is not wanted, the solution is to let the plugin issue all requests without expecting (caching) any request, unless we want the plugin to block zebra shutdown for all requests to be answered. Similarly, when finalizing, the plugin answers with a failure to zebra. This is so that it believes that all deletions failed, preventing it from removing routes (*) from the kernel VRF. This is so that, should zebra fail but not other daemons (BGP), those can still communicate using the kernel routing tables. Signed-off-by: Fredi Raspall <[email protected]>
