-Subject: [PATCH] Check SOA owner names in zone transfers
-
-An IXFR containing SOA records with owner names different than the
-transferred zone's origin can result in named serving a version of that
-zone without an SOA record at the apex.  This causes a RUNTIME_CHECK
-assertion failure the next time such a zone is refreshed.  Fix by
-immediately rejecting a zone transfer (either an incremental or
-non-incremental one) upon detecting an SOA record not placed at the apex
-of the transferred zone.

+Subject: [PATCH] Add additional name checks when using a forwarder
+
+When using a forwarder, check that the owner name of response
+records are within the bailiwick of the forwarded name space.
+
+(cherry picked from commit e8df2802ac62016ea68585893eb4310fc3329028)
+
+Check that the forward declaration is unchanged and not overridden
+
+If we are using a fowarder, in addition to checking that names to
+be cached are subdomains of the forwarded namespace, we must also
+check that there are no subsidiary forwarded namespaces which would
+take precedence. To be safe, we don't cache any responses if the
+forwarding configuration has changed since the query was sent.
+
+(cherry picked from commit 590f8698fc876d6d72f75cf35359e7546c3af972)
+
+Check cached names for possible "forward only" clause
+
+When caching additional and glue data *not* from a forwarder, we must
+check that there is no "forward only" clause covering the owner name
+that would take precedence.  Such names would normally be allowed by
+baliwick rules, but a "forward only" zone introduces a new baliwick
+scope.
+
+(cherry picked from commit 4a144fae16e70517be894a971cef1d085ee68ebe)
+
+Look for zones deeper than the current domain or forward name
+
+When caching glue, we need to ensure that there is no closer
+source of truth for the name. If the owner name for the glue
+record would be answered by a locally configured zone, do not
+cache.
+
+(cherry picked from commit 42f8c538d3fb9d075b98d82688aeb71621798754)
+
+Avoid use of compound literals
+
+Compound literals are not used in BIND 9.11, in order to ensure backward
+compatibility with ancient compilers.  Rework the relevant parts of the
+BIND 9.11 backport of the CVE-2021-25220 fix so that compound literals
+are not used.

+Subject: [PATCH] Bound the amount of work performed for delegations
+
+Limit the amount of database lookups that can be triggered in
+fctx_getaddresses() (i.e. when determining the name server addresses to
+query next) by setting a hard limit on the number of NS RRs processed
+for any delegation encountered.  Without any limit in place, named can
+be forced to perform large amounts of database lookups per each query
+received, which severely impacts resolver performance.
+
+The limit used (20) is an arbitrary value that is considered to be big
+enough for any sane DNS delegation.

+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] Fail the DNSSEC validation on the first failure
+
+Be more strict when encountering DNSSEC validation failures - fail on
+the first failure.  This will break domains that have DNSSEC signing
+keys with duplicate key ids, but this is something that's much easier
+to fix on the authoritative side, so we are just going to be strict
+on the resolver side where it is causing performance problems.
+
+(cherry picked from commit 8b7ecba9885e163c07c2dd3e1ceab79b2ba89e34)
+
+Add normal and slow task queues
+
+Split the task manager queues into normal and slow task queues, so we
+can move the tasks that blocks processing for a long time (like DNSSEC
+validation) into the slow queue which doesn't block fast
+operations (like responding from the cache).  This mitigates the whole
+class of KeyTrap-like issues.

+
+Don't iterate from start every time we select new signing key

+we stopped the iteration and just continue from that place instead
+of iterating from the start over and over again each time.

-Subject: [PATCH] Inactive incorrectly incremented
-
-It is possible to have two threads destroying an rbtdb at the same
-time when detachnode() executes and removes the last reference to
-a node between exiting being set to true for the node and testing
-if the references are zero in maybe_free_rbtdb().  Move NODE_UNLOCK()
-to after checking if references is zero to prevent detachnode()
-changing the reference count too early.
-
-(cherry picked from commit 859d2fdad6d1c6ff20083a4c463a929cbeb26438)
-(cherry picked from commit 25150c15e7cfa73289f04470e2e699ebb7c28fef)

+Subject: [PATCH] Have dns_zt_apply lock the zone table
+
+There where a number of places where the zone table should have
+been locked, but wasn't, when dns_zt_apply was called.
+
+Added a isc_rwlocktype_t type parameter to dns_zt_apply and adjusted
+all calls to using it.  Removed locks in callers.
+
+Modified upstream commit for v9_11

+Subject: [PATCH] Do not keep stale records by default
+
+By default set max-stale-ttl to 0, unless stale-answer-enable yes. This
+were enabled by mistake when backporting fix for CVE-2023-2828. It
+causes increased cache usage on servers not wanting to serve stale
+records. Fix that by setting smart defaults based on stale answers
+enabled with possible manual tuning.

+Subject: [PATCH] Use RESOLVER_NTASKS_PERCPU - 32 for regular tuning, 8 for
+ small
+
+Modify original upstream commit 0d80266f7e3, add high limit of used
+tasks. Minimum would be lower on machines with few cpus, but maximum
+would stay unchanged. Should prevent negatives of this change.

+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] test failure conditions
+
+verify that updates are refused when the client is disallowed by
+allow-query, and update forwarding is refused when the client is
+is disallowed by update-forwarding.
+
+verify that "too many DNS UPDATEs" appears in the log file when too
+many simultaneous updates are processing.
+
+(cherry picked from commit b91339b80e5b82a56622c93cc1e3cca2d0c11bc0)
