 Subject: [PATCH] Fix CVE-2020-8624
 5481.	[security]	"update-policy" rules of type "subdomain" were
 			incorrectly treated as "zonesub" rules, which allowed
 			keys used in "subdomain" rules to update names outside
 			of the specified subdomains. The problem was fixed by
 			making sure "subdomain" rules are again processed as
 			described in the ARM. (CVE-2020-8624) [GL #2055]

 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.
 (cherry picked from commit 3a44097fd6c6c260765b628cd1d2c9cb7efb0b2a)
 (cherry picked from commit bf2ea6d8525bfd96a84dad221ba9e004adb710a8)

 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.

 From 4c20ab54ec503f65d8ee0b863cbf41103d95130a Mon Sep 17 00:00:00 2001

 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.
 (cherry picked from commit db083a21726300916fa0b9fd8a433a796fedf636)
 Don't iterate from start every time we select new signing key
 Improve the selecting of the new signing key by remembering where
 we stopped the iteration and just continue from that place instead
 of iterating from the start over and over again each time.
 (cherry picked from commit 75faeefcab47e4f1e12b358525190b4be90f97de)
 Optimize selecting the signing key
 Don't parse the crypto data before parsing and matching the id and the
 algorithm.
 (cherry picked from commit b38552cca7200a72658e482f8407f57516efc5db)
 6322.	[security]	Specific DNS answers could cause a denial-of-service
 			condition due to DNS validation taking a long time.
 			(CVE-2023-50387) [GL #4424]
 			The same code change also addresses another problem:
 			preparing NSEC3 closest encloser proofs could exhaust
 			available CPU resources. (CVE-2023-50868) [GL #4459]

 Subject: [PATCH] Allow global runtime definition by DNS_RBTDB_MAX_RTYPES
 Modify rbtdb to not set it only at runtime, but allow setting that also
 in runtime via environment variable. It is still possible to modify
 default during the build define. In addition to it allows runtime change
 also. Can be positive number to set limit, 0 disabled the check.
 Similarly add also DNS_RDATASET_MAX_RECORDS to set maximum number of
 records for a single name. This must be positive number, 0 is no accepted.
 These replaces max-records-per-type and max-types-per-name in later
 versions. But can be configured only by environment and can be
 configured only globally, not in each view or zone.

 Subject: [PATCH] [9.11][CVE-2024-1737] Add a limit to the number of RRs in
 RRSets
 Add a limit to the number of RRs in RRSets
 Previously, the number of RRs in the RRSets were internally unlimited.
 As the data structure that holds the RRs is just a linked list, and
 there are places where we just walk through all of the RRs, adding an
 RRSet with huge number of RRs inside would slow down processing of said
 RRSets.
 The fix for end-of-life branches make the limit compile-time only for
 simplicity and the limit can be changed at the compile time by adding
 following define to CFLAGS:
    -DDNS_RDATASET_MAX_RECORDS=<limit>
 (cherry picked from commit c5c4d00c38530390c9e1ae4c98b65fbbadfe9e5e)
 (cherry picked from commit 7f705778af729ada7fec36ac4b456c73329bd996)
 (cherry picked from commit b9b5485b22c364fb88c27aa04bad4c8f616da3fa)
 Add a limit to the number of RR types for single name
 Previously, the number of RR types for a single owner name was limited
 only by the maximum number of the types (64k).  As the data structure
 that holds the RR types for the database node is just a linked list, and
 there are places where we just walk through the whole list (again and
 again), adding a large number of RR types for a single owner named with
 would slow down processing of such name (database node).
 Add a hard-coded limit (100) to cap the number of the RR types for a single
 owner.  The limit can be changed at the compile time by adding following
 define to CFLAGS:
    -DDNS_RBTDB_MAX_RTYPES=<limit>
 (cherry picked from commit 538b843d84f49ba5125ff545e3d0cf1c8434a8f2)
 (cherry picked from commit 3f10d6eff035702796ba82cd28b9f7cf9836e743)
 Optimize the slabheader placement for certain RRTypes
 Mark the infrastructure RRTypes as "priority" types and place them at
 the beginning of the rdataslab header data graph.  The non-priority
 types either go right after the priority types (if any).
 (cherry picked from commit 3ac482be7fd058d284e89873021339579fad0615)
 (cherry picked from commit 23a4652346fb2877d6246b1eebaa967969dbde16)
 [9.11][CVE-2024-1737 (part 2)] Be smarter about refusing to add many RR types to the database
 Expand the list of the priority types
 Add HTTPS, SVCB, SRV, PTR, NAPTR, DNSKEY and TXT records to the list of
 the priority types that are put at the beginning of the slabheader list
 for faster access and to avoid eviction when there are more types than
 the max-types-per-name limit.
 (cherry picked from commit b27c6bcce894786a8e082eafd59eccbf6f2731cb)
 (cherry picked from commit 3e0a67e4bdb253dae3a03a45c1aa117239a3313d)
 Be smarter about refusing to add many RR types to the database
 Instead of outright refusing to add new RR types to the cache, be a bit
 smarter:
 1. If the new header type is in our priority list, we always add either
   positive or negative entry at the beginning of the list.
 2. If the new header type is negative entry, and we are over the limit,
   we mark it as ancient immediately, so it gets evicted from the cache
   as soon as possible.
 3. Otherwise add the new header after the priority headers (or at the
   head of the list).
 4. If we are over the limit, evict the last entry on the normal header
   list.
 (cherry picked from commit 57cd34441a1b4ecc9874a4a106c2c95b8d7a3120)
 (cherry picked from commit e4d7ce686bb38428eddc7e33b40057d68eca9a6e)

 Subject: [PATCH] Replace isc_safe routines with their OpenSSL counter parts
 (cherry picked from commit 66ba2fdad583d962a1f4971c85d58381f0849e4d)
 Remove isc_safe_memcompare, it's not needed anywhere and can't be replaced with CRYPTO_memcmp()
 (cherry picked from commit b105ccee68ccc3c18e6ea530063b3c8e5a42571c)
 Fix the isc_safe_memwipe() usage with (NULL, >0)
 (cherry picked from commit 083461d3329ff6f2410745848a926090586a9846)

 Subject: [PATCH] Prevent crash on dst initialization failure
 server might be created, but not yet fully initialized, when fatal
 function is called. Check both server and task before attaching
 exclusive task.

 Subject: [PATCH] Use proper entropy to initialize tsig keyname
 Random names used on GSS backed nsupdate can conflict in specific
 situations. That might include starting a lot of machines from
 containers, where they took all similar time to start. PID and timestamp
 would be similar and therefore randomness is quite low. Use entropy to
 generate more random identifier and reduce chance of conflict.

 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.
 (cherry picked from commit 7c47254a140c3e9cf383cda73c7b6a55c4782826)

 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)

 From 3d84c651f823cb90b73fd736d32ad6de57b11610 Mon Sep 17 00:00:00 2001
 From: Evan Hunt <each@isc.org>
 Date: Wed, 9 Nov 2022 21:56:16 -0800
 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)
