+Subject: [PATCH] add an update quota
+
+limit the number of simultaneous DNS UPDATE events that can be
+processed by adding a quota for update and update forwarding.
+this quota currently, arbitrarily, defaults to 100.
+
+also add a statistics counter to record when the update quota
+has been exceeded.
+

+Subject: [PATCH] move update ACL and update-policy checks before quota
+
+check allow-update, update-policy, and allow-update-forwarding before
+consuming quota slots, so that unauthorized clients can't fill the
+quota.
+
+(this moves the access check before the prerequisite check, which
+violates the precise wording of RFC 2136. however, RFC co-author Paul
+Vixie has stated that the RFC is mistaken on this point; it should have
+said that access checking must happen *no later than* the completion of
+prerequisite checks, not that it must happen exactly then.)
+
+(cherry picked from commit 964f559edb5036880b8e463b8f190b9007ee055d)

+Subject: [PATCH] Cancel all fetch events in dns_resolver_cancelfetch()
+
+Although 'dns_fetch_t' fetch can have two associated events, one for
+each of 'DNS_EVENT_FETCHDONE' and 'DNS_EVENT_TRYSTALE' types, the
+dns_resolver_cancelfetch() function is designed in a way that it
+expects only one existing event, which it must cancel, and when it
+happens so that 'stale-answer-client-timeout' is enabled and there
+are two events, only one of them is canceled, and it results in an
+assertion in dns_resolver_destroyfetch(), when it finds a dangling
+event.
+
+Change the logic of dns_resolver_cancelfetch() function so that it
+cancels both the events (if they exist), and in the right order.
+
