stop absolute/relative dual use of RR.ttl. now RR.ttl is *always* the *relative* ttl value. we derive absolute timeout in RR.expire. remove unused lookuptime field in DN. replace refs and keep with mark field in DN. we do not care about the number of references. only *iff* it is referenced, so use a single bit for that (bit 0). for keep, we use bit 1. remove dolock parameter in dnagenever(), it is not needed. we always need to lock. mark local dns servers and domains as never to be aged. the keeper bit is *just* a cache optimization, preventing the domain and the domains it points to from being flushed. it should not be used as a write protect bit in rrattach() for preventing spoofing as it will prevent updates of say, cname domains. remove "removing spam ..." message. these are usualy just hints, so normal. still, remove the hint as we currently do no check if the nameserver has authority over the cname domain. remove "mydnsquery: trying to send to myself (%s); bzzzt" message. this can happen when myaddr() fails for other reasons. myaddr() will print error for us anyway. |
