-Subject: [PATCH] Improve RBT overmem cache cleaning
-
-When cache memory usage is over the configured cache size (overmem) and
-we are cleaning unused entries, it might not be enough to clean just two
-entries if the entries to be expired are smaller than the newly added
-rdata. This could be abused by an attacker to cause a remote Denial of
-Service by possibly running out of the operating system memory.
-
-Currently, the addrdataset() tries to do a single TTL-based cleaning
-considering the serve-stale TTL and then optionally moves to overmem
-cleaning if we are in that condition. Then the overmem_purge() tries to
-do another single TTL based cleaning from the TTL heap and then continue
-with LRU-based cleaning up to 2 entries cleaned.
-
-Squash the TTL-cleaning mechanism into single call from addrdataset(),
-but ignore the serve-stale TTL if we are currently overmem.
-
-Then instead of having a fixed number of entries to clean, pass the size
-of newly added rdatasetheader to the overmem_purge() function and
-cleanup at least the size of the newly added data. This prevents the
-cache going over the configured memory limit (`max-cache-size`).
-
-Additionally, refactor the overmem_purge() function to reduce for-loop
-nesting for readability.

-Subject: [PATCH] Fix serve-stale hang at shutdown
-
-The 'refresh_rrset' variable is used to determine if we can detach from
-the client. This can cause a hang on shutdown. To fix this, move setting
-of the 'nodetach' variable up to where 'refresh_rrset' is set (in
-query_lookup(), and thus not in ns_query_done()), and set it to false
-when actually refreshing the RRset, so that when this lookup is
-completed, the client will be detached.
