      Disable lame-ttl cache · 8fe18c05
      Ondřej Surý authored and Michał Kępień's avatar Michał Kępień committed
      The lame-ttl cache is implemented in ADB as per-server locked
      linked-list "indexed" with <qname,qtype>.  This list has to be walked
      every time there's a new query or new record added into the lame cache.
      Determined attacker can use this to degrade performance of the resolver.
      
      Resolver testing has shown that disabling the lame cache has little
      impact on the resolver performance and it's a minimal viable defense
      against this kind of attack.
