(CVE-2022-38178) [GL #3487]

5961. [security] Fix memory leak in ECDSA verify processing.
(CVE-2022-38177) [GL #3487]

5960. [security] Fix serve-stale crash that could happen when
stale-answer-client-timeout was set to 0 and there was
a stale CNAME in the cache for an incoming query.
(CVE-2022-3080) [GL #3517]

5957. [security] Prevent excessive resource use while processing large
delegations. (CVE-2022-2795) [GL #3394]

5956. [func] Make RRL code treat all QNAMEs that are subject to
wildcard processing within a given zone as the same
name. [GL #3459]

5955. [port] The libxml2 library has deprecated the usage of
xmlInitThreads() and xmlCleanupThreads() functions. Use
xmlInitParser() and xmlCleanupParser() instead.
[GL #3518]

5954. [func] Fallback to IDNA2003 processing in dig when IDNA2008
conversion fails. [GL #3485]

5953. [bug] Fix a crash on shutdown in delete_trace_entry(). Add
mctx attach/detach pair to make sure that the memory
context used by a memory pool is not destroyed before
the memory pool itself. [GL #3515]

5952. [bug] Use quotes around address strings in YAML output.
[GL #3511]

5951. [bug] In some cases, the dnstap query_message field was
erroneously set when logging response messages.
[GL #3501]

5948. [bug] Fix nsec3.c:dns_nsec3_activex() function, add a missing
dns_db_detachnode() call. [GL #3500]

5945. [bug] If parsing /etc/bind.key failed, delv could assert
when trying to parse the built in trust anchors as
the parser hadn't been reset. [GL !6468]

5942. [bug] Fix tkey.c:buildquery() function's error handling by
adding the missing cleanup code. [GL #3492]

5941. [func] Zones with dnssec-policy now require dynamic DNS or
inline-siging to be configured explicitly. [GL #3381]

5936. [bug] Don't enable serve-stale for lookups that error because
it is a duplicate query or a query that would be
dropped. [GL #2982]

--- 9.16.32 released ---

5934. [func] Improve fetches-per-zone fetch limit logging to log
the final allowed and spilled values of the fetch
counters before the counter object gets destroyed.
[GL #3461]

5933. [port] Automatically disable RSASHA1 and NSEC3RSASHA1 in
named on Fedorda 33, Oracle Linux 9 and RHEL9 when
they are disabled by the security policy. [GL #3469]

5932. [bug] Fix rndc dumpdb -expired and always include expired
RRsets, not just for RBTDB_VIRTUAL time window.
[GL #3462]

5929. [bug] The "max-zone-ttl" option in "dnssec-policy" was
not fully effective; it was used for timing key
rollovers but did not actually place an upper limit
on TTLs when loading a zone. This has been
corrected, and the documentation has been clarified
to indicate that the old "max-zone-ttl" zone option
is now ignored when "dnssec-policy" is in use.
[GL #2918]

5924. [func] When it's necessary to use AXFR to respond to an
IXFR request, a message explaining the reason
is now logged at level info. [GL #2683]

5923. [bug] Fix inheritance for dnssec-policy when checking for
inline-signing. [GL #3438]

5922. [bug] Forwarding of UPDATE message could fail with the
introduction of netmgr. This has been fixed. [GL #3389]

--- 9.16.31 released ---

5917. [bug] Update ifconfig.sh script as is miscomputed interface
identifiers when destroying interfaces. [GL #3061]

5915. [bug] Detect missing closing brace (}) and computational
overflows in $GENERATE directives. [GL #3429]

5913. [bug] Fix a race between resolver query timeout and
validation in resolver.c:validated(). Remove
resolver.c:maybe_destroy() as it is no loger needed.
[GL #3398]

5909. [bug] The server-side destination port was missing from dnstap
captures of client traffic. [GL #3309]

5905. [bug] When the TCP connection would be closed/reset between
the connect/accept and the read, the uv_read_start()
return value would be unexpected and cause an assertion
failure. [GL #3400]

5903. [bug] When named checks that the OPCODE in a response matches
that of the request, if there is a mismatch named logs
an error. Some of those error messages incorrectly
used RCODE instead of OPCODE to lookup the nemonic.
This has been corrected. [GL !6420]

--- 9.16.30 released ---

5899. [func] Don't try to process DNSSEC-related and ZONEMD records
in catz. [GL #3380]

5890. [bug] When the fetches-per-server quota was adjusted
because of an authoritative server timing out more
or less frequently, it was incorrectly set to 1
rather than the intended value. This has been
fixed. [GL #3327]

5888. [bug] Only write key files if the dnssec-policy keymgr has
changed the metadata. [GL #3302]

5823. [func] Replace hazard pointers based lock-free list with
locked-list based queue that's simpler and has no or
little performance impact. [GL #3180]

--- 9.16.29 released ---

5885. [bug] RPZ NSIP and NSDNAME rule processing didn't handle stub
and static-stub zones at or above the query name. This
has now been addressed. [GL #3232]

5881. [bug] dig +nssearch could hang in rare cases when recv_done()
callback was being called earlier than send_done().
[GL #3278]

5880. [func] Add new named command-line option -C to print built-in
defaults. [GL #1326]

5879. [contrib] dlz: Add FALLTHROUGH and UNREACHABLE macros. [GL #3306]

5874. [bug] keymgr didn't work with python 3.11. [GL !6157]

5866. [bug] Work around a jemalloc quirk which could trigger an
out-of-memory condition in named over time. [GL #3287]

5863. [bug] If there was a pending negative cache DS entry,
validations depending upon it could fail. [GL #3279]

5858. [bug] Don't remove CDS/CDNSKEY DELETE records on zone sign
when using 'auto-dnssec maintain;'. [GL #2931]

--- 9.16.28 released ---

5856. [bug] The "starting maxtime timer" message related to outgoing
zone transfers was incorrectly logged at the ERROR level
instead of DEBUG(1). [GL #3208]

5852. [func] Add new "reuseport" option to enable/disable load
balancing of sockets. [GL #3249]

5843. [bug] When an UPDATE targets a zone that is not configured,
the requested zone name is now logged in the "not
authoritative" error message, so that it is easier to
track down problematic update clients. [GL #3209]

5836. [bug] Quote the dns64 prefix in error messages that complain
about problems with it, to avoid confusion with the
following dns64 ACLs. [GL #3210]

5834. [cleanup] C99 variable-length arrays are difficult to use safely,
so avoid them except in test code. [GL #3201]

5828. [bug] Replace single TCP write timer with per-TCP write
timers. [GL #3200]

5824. [bug] Invalid dnssec-policy definitions were being accepted
where the defined keys did not cover both KSK and ZSK
roles for a given algorithm. This is now checked for
and the dnssec-policy is rejected if both roles are
not present for all algorithms in use. [GL #3142]

--- 9.16.27 released ---

5818. [security] A synchronous call to closehandle_cb() caused
isc__nm_process_sock_buffer() to be called recursively,
which in turn left TCP connections hanging in the
CLOSE_WAIT state blocking indefinitely when
out-of-order processing was disabled. (CVE-2022-0396)
[GL #3112]

5817. [security] The rules for acceptance of records into the cache
have been tightened to prevent the possibility of
poisoning if forwarders send records outside
the configured bailiwick. (CVE-2021-25220) [GL #2950]

5816. [bug] Make BIND compile with LibreSSL 3.5.0, as it was using
not very accurate pre-processor checks for using shims.
[GL #3172]

5815. [bug] If an oversized key name of a specific length was used
in the text form of an HTTP or SVBC record, an INSIST
could be triggered when parsing it. [GL #3175]

5814. [bug] The RecursClients statistics counter could underflow
in certain resolution scenarios. [GL #3147]

5811. [bug] Reimplement the maximum and idle timeouts for outgoing
zone transfers. [GL #1897]

5807. [bug] Add a TCP "write" timer, and time out writing
connections after the "tcp-idle-timeout" period
has elapsed. [GL #3132]

5804. [func] Add a debug log message when starting and ending
the task exclusive mode. [GL #3137]

--- 9.16.26 released ---

5801. [bug] Log "quota reached" message when hard quota
is reached when accepting a connection. [GL #3125]

5800. [func] Add ECS support to the DLZ interface. [GL #3082]

5797. [bug] A failed view configuration during a named
reconfiguration procedure could cause inconsistencies
in BIND internal structures, causing a crash or other
unexpected errors. [GL #3060]

5795. [bug] rndc could crash when interrupted by a signal
before receiving a response. [GL #3080]

5793. [bug] Correctly detect and enable UDP recvmmsg support
in all versions of libuv that support it. [GL #3095]

--- 9.16.25 released ---

5789. [bug] Allow replacing expired zone signatures with
signatures created by the KSK. [GL #3049]

5788. [bug] An assertion could occur if a catalog zone event was
scheduled while the task manager was being shut
down. [GL #3074]

5787. [doc] Update 'auto-dnssec' documentation, it may only be
activated at zone level. [GL #3023]

5786. [bug] Defer detaching from zone->raw in zone_shutdown() if
the zone is in the process of being dumped to disk, to
ensure that the unsigned serial number information is
always written in the raw-format header of the signed
version on an inline-signed zone. [GL #3071]

5785. [bug] named could leak memory when two dnssec-policy clauses
had the same name. named failed to log this error.
[GL #3085]

5776. [bug] Add a missing isc_condition_destroy() for nmsocket
condition variable and add missing isc_mutex_destroy()
for nmworker lock. [GL #3051]

5676. [func] Memory use in named was excessive. This has been
addressed by:
- Replacing locked memory pools with normal memory
allocations.
- Reducing the number of retained free items in
unlocked memory pools.
- Disabling the internal allocator by default.
"named -M internal" turns it back on.
[GL #2398]

--- 9.16.24 released ---

5773. [func] Change the message when accepting TCP connection has
failed to say "Accepting TCP connection failed" and
change the log level for ISC_R_NOTCONNECTED, ISC_R_QUOTA
and ISC_R_SOFTQUOTA results codes from ERROR to INFO.
[GL #2700]

5768. [bug] dnssec-dsfromkey failed to omit revoked keys. [GL #853]

5764. [bug] dns_sdlz_putrr failed to process some valid resource
records. [GL #3021]

5762. [bug] Fix a "named" crash related to removing and restoring a
`catalog-zone` entry in the configuration file and
running `rndc reconfig`. [GL #1608]

5758. [bug] mdig now honors the operating system's preferred
ephemeral port range. [GL #2374]

5757. [test] Replace sed in nsupdate system test with awk to
construct the nsupdate command. The sed expression
was not reliably changing the ttl. [GL #3003]

--- 9.16.23 released ---

5752. [bug] Fix an assertion failure caused by missing member zones
during a reload of a catalog zone. [GL #2308]

5750. [bug] Fix a bug when comparing two RSA keys. There was a typo
which caused the "p" prime factors to not being
compared. [GL #2972]

5737. [bug] Address Coverity warning in lib/dns/dnssec.c.
[GL #2935]

--- 9.16.22 released ---

5736. [security] The "lame-ttl" option is now forcibly set to 0. This
effectively disables the lame server cache, as it could
previously be abused by an attacker to significantly
degrade resolver performance. (CVE-2021-25219)
[GL #2899]

5724. [bug] Address a potential deadlock when checking zone content
consistency. [GL #2908]

5723. [bug] Change 5709 broke backward compatibility for the
"check-names master ..." and "check-names slave ..."
options. This has been fixed. [GL #2911]

5720. [contrib] Old-style DLZ drivers that had to be enabled at
build-time have been marked as deprecated. [GL #2814]

5719. [func] The "map" zone file format has been marked as
deprecated. [GL #2882]

5717. [func] The "cache-file" option, which was documented as "for
testing purposes only" and not to be used, has been
removed. [GL #2903]

5716. [bug] Multiple library names were mistakenly passed to the
krb5-config utility when ./configure was invoked with
the --with-gssapi=[/path/to/]krb5-config option. This
has been fixed by invoking krb5-config separately for
each required library. [GL #2866]

5715. [func] Add a check for ports specified in "*-source(-v6)"
options clashing with a global listening port. Such a
configuration was already unsupported, but it failed
silently; it is now treated as an error. [GL #2888]

5714. [bug] Remove the "adjust interface" mechanism which was
responsible for setting up listeners on interfaces when
the "*-source(-v6)" address and port were the same as
the "listen-on(-v6)" address and port. Such a
configuration is no longer supported; under certain
timing conditions, that mechanism could prevent named
from listening on some TCP ports. This has been fixed.
[GL #2852]

5712. [doc] Add deprecation notice about removing native PKCS#11
support in the next major BIND 9 release. [GL #2691]

--- 9.16.21 released ---

5711. [bug] "map" files exceeding 2GB in size failed to load due to
a size comparison that incorrectly treated the file size
as a signed integer. [GL #2878]

5710. [port] win32: incorrect parentheses resulted in the wrong
sizeof() tests being used to pick the appropriate
Windows atomic operations for the object's size.
[GL #2891]

5709. [cleanup] Enum values throughout the code have been updated
to use the terms "primary" and "secondary" instead of
"master" and "slave", respectively. [GL #1944]

5708. [bug] The thread-local isc_tid_v variable was not properly
initialized when running BIND 9 as a Windows Service,
leading to a crash on startup. [GL #2837]

5705. [bug] Change #5686 altered the internal memory structure of
zone databases, but neglected to update the MAPAPI value
for zone files in "map" format. This caused named to
attempt to load incompatible map files, triggering an
assertion failure on startup. The MAPAPI value has now
been updated, so named rejects outdated files when
encountering them. [GL #2872]

5704. [bug] Change #5317 caused the EDNS TCP Keepalive option to be
ignored inadvertently in client requests. It has now
been fixed and this option is handled properly again.
[GL #1927]

5701. [bug] named-checkconf failed to detect syntactically invalid
values of the "key" and "tls" parameters used to define
members of remote server lists. [GL #2461]

5700. [bug] When a member zone was removed from a catalog zone,
journal files for the former were not deleted.
[GL #2842]

5699. [func] Data structures holding DNSSEC signing statistics are
now grown and shrunk as necessary upon key rollover
events. [GL #1721]

5698. [bug] When a DNSSEC-signed zone which only has a single
signing key available is migrated to use KASP, that key
is now treated as a Combined Signing Key (CSK).
[GL #2857]

5696. [protocol] Support for HTTPS and SVCB record types has been added.
(This does not include ADDITIONAL section processing for
these record types, only basic support for RR type
parsing and printing.) [GL #1132]

5694. [bug] Stale data in the cache could cause named to send
non-minimized queries despite QNAME minimization being
enabled. [GL #2665]

5691. [bug] When a dynamic zone was made available in another view
using the "in-view" statement, running "rndc freeze"
always reported an "already frozen" error even though
the zone was successfully frozen. [GL #2844]

5690. [func] dnssec-signzone now honors Predecessor and Successor
metadata found in private key files: if a signature for
an RRset generated by the inactive predecessor exists
and does not need to be replaced, no additional
signature is now created for that RRset using the
successor key. This enables dnssec-signzone to gradually
replace RRSIGs during a ZSK rollover. [GL #1551]

Import bind-9.16.20

--- 9.16.20 released ---

5689. [security] An assertion failure occurred when named attempted to
send a UDP packet that exceeded the MTU size, if
Response Rate Limiting (RRL) was enabled.
(CVE-2021-25218) [GL #2856]

5688. [bug] Zones using KASP and inline-signed zones failed to apply
changes from the unsigned zone to the signed zone under
certain circumstances. This has been fixed. [GL #2735]

5687. [bug] "rndc reload <zonename>" could trigger a redundant
reload for an inline-signed zone whose zone file was not
modified since the last "rndc reload". This has been
fixed. [GL #2855]

5686. [func] The number of internal data structures allocated for
each zone was reduced. [GL #2829]

5685. [bug] named failed to check the opcode of responses when
performing zone refreshes, stub zone updates, and UPDATE
forwarding. This has been fixed. [GL #2762]

5682. [bug] Some changes to "zone-statistics" settings were not
properly processed by "rndc reconfig". This has been
fixed. [GL #2820]

5681. [func] Relax the checks in the dns_zone_cdscheck() function to
allow CDS and CDNSKEY records in the zone that do not
match an existing DNSKEY record, as long as the
algorithm matches. This allows a clean rollover from one
provider to another in a multi-signer DNSSEC
configuration. [GL #2710]

5679. [func] Thread affinity is no longer set. [GL #2822]

5678. [bug] The "check DS" code failed to release all resources upon
named shutdown when a refresh was in progress. This has
been fixed. [GL #2811]

5672. [bug] Authentication of rndc messages could fail if a
"controls" statement was configured with multiple key
algorithms for the same listener. This has been fixed.
[GL #2756]

--- 9.16.19 released ---

5671. [bug] A race condition could occur where two threads were
competing for the same set of key file locks, leading to
a deadlock. This has been fixed. [GL #2786]

5670. [bug] create_keydata() created an invalid placeholder keydata
record upon a refresh failure, which prevented the
database of managed keys from subsequently being read
back. This has been fixed. [GL #2686]

5669. [func] KASP support was extended with the "check DS" feature.
Zones with "dnssec-policy" and "parental-agents"
configured now check for DS presence and can perform
automatic KSK rollovers. [GL #1126]

5668. [bug] Rescheduling a setnsec3param() task when a zone failed
to load on startup caused a hang on shutdown. This has
been fixed. [GL #2791]

5667. [bug] The configuration-checking code failed to account for
the inheritance rules of the "dnssec-policy" option.
This has been fixed. [GL #2780]

5666. [doc] The safe "edns-udp-size" value was tweaked to match the
probing value from BIND 9.16 for better compatibility.
[GL #2183]

5665. [bug] If nsupdate sends an SOA request and receives a REFUSED
response, it now fails over to the next available
server. [GL #2758]

5664. [func] For UDP messages larger than the path MTU, named now
sends an empty response with the TC (TrunCated) bit set.
In addition, setting the DF (Don't Fragment) flag on
outgoing UDP sockets was re-enabled. [GL #2790]

5662. [bug] Views with recursion disabled are now configured with a
default cache size of 2 MB unless "max-cache-size" is
explicitly set. This prevents cache RBT hash tables from
being needlessly preallocated for such views. [GL #2777]

5661. [bug] Change 5644 inadvertently introduced a deadlock: when
locking the key file mutex for each zone structure in a
different view, the "in-view" logic was not considered.
This has been fixed. [GL #2783]

5658. [bug] Increasing "max-cache-size" for a running named instance
(using "rndc reconfig") did not cause the hash tables
used by cache databases to be grown accordingly. This
has been fixed. [GL #2770]

5655. [bug] Signed, insecure delegation responses prepared by named
either lacked the necessary NSEC records or contained
duplicate NSEC records when both wildcard expansion and
CNAME chaining were required to prepare the response.
This has been fixed. [GL #2759]

5653. [bug] A bug that caused the NSEC3 salt to be changed on every
restart for zones using KASP has been fixed. [GL #2725]

--- 9.16.18 released ---

5660. [bug] The configuration-checking code failed to account for
the inheritance rules of the "key-directory" option.
[GL #2778]

5659. [bug] When preparing DNS responses, named could replace the
letters 'W' (uppercase) and 'w' (lowercase) with '\000'.
This has been fixed. [GL #2779]

--- 9.16.17 released ---

5652. [bug] A copy-and-paste error in change 5584 caused the
IP_DONTFRAG socket option to be enabled instead of
disabled. This has been fixed. [GL #2746]

5651. [func] Refactor zone dumping to be processed asynchronously via
the uv_work_t thread pool API. [GL #2732]

5650. [bug] Prevent a crash that could occur if serve-stale was
enabled and a prefetch was triggered during a query
restart. [GL #2733]

5649. [bug] If a query was answered with stale data on a server with
DNS64 enabled, an assertion could occur if a non-stale
answer arrived afterward. [GL #2731]

5648. [bug] The calculation of the estimated IXFR transaction size
in dns_journal_iter_init() was invalid. [GL #2685]

5644. [bug] Fix a race condition in reading and writing key files
for zones using KASP and configured in multiple views.
[GL #1875]

5643. [cleanup] "make install" no longer creates an empty
${localstatedir}/run directory. [GL #2709]

5642. [bug] Zones which are configured in multiple views with
different values set for "dnssec-policy" and with
identical values set for "key-directory" are now
detected and treated as a configuration error.
[GL #2463]

5641. [bug] Address a potential memory leak in
dst_key_fromnamedfile(). [GL #2689]

5639. [bug] Check that the first and last SOA record of an AXFR are
consistent. [GL #2528]

5638. [bug] Improvements related to network manager/task manager
integration:
- isc_managers_create() and isc_managers_destroy()
functions were added to handle setup and teardown of
netmgr, taskmgr, timermgr, and socketmgr, since these
require a precise order of operations now.
- Event queue processing is now quantized to prevent
infinite looping.
- The netmgr can now be paused from within a netmgr
thread.
- Deadlocks due to a conflict between netmgr's
pause/resume and listen/stoplistening operations were
fixed.
[GL #2654]

5633. [doc] The "inline-signing" option was incorrectly described as
being inherited from the "options"/"view" levels and was
incorrectly accepted at those levels without effect.
This has been fixed. [GL #2536]

5624. [func] Task manager events are now processed inside network
manager loops. The task manager no longer needs its own
set of worker threads, which improves resolver
performance. [GL #2638]

--- 9.16.16 released ---

5637. [func] Change the default value of the "max-ixfr-ratio" option
to "unlimited". [GL #2671]

5636. [bug] named and named-checkconf did not report an error when
multiple zones with the "dnssec-policy" option set were
using the same zone file. This has been fixed.
[GL #2603]

5635. [bug] Journal compaction could fail when a journal with
invalid transaction headers was not detected at startup.
This has been fixed. [GL #2670]

5634. [bug] If "dnssec-policy" was active and a private key file was
temporarily offline during a rekey event, named could
incorrectly introduce replacement keys and break a
signed zone. This has been fixed. [GL #2596]

5633. [doc] The "inline-signing" option was incorrectly described as
being inherited from the "options"/"view" levels and was
incorrectly accepted at those levels without effect.
This has been fixed. [GL #2536]

5632. [func] Add a new built-in KASP, "insecure", which is used to
transition a zone from a signed to an unsigned state.
The existing built-in KASP "none" should no longer be
used to unsign a zone. [GL #2645]

5631. [protocol] Update the implementation of the ZONEMD RR type to match
RFC 8976. [GL #2658]

5630. [func] Treat DNSSEC responses containing NSEC3 records with
iteration counts greater than 150 as insecure.
[GL #2445]

5629. [func] Reduce the maximum supported number of NSEC3 iterations
that can be configured for a zone to 150. [GL #2642]

5627. [bug] RRSIG(SOA) RRsets placed anywhere other than at the zone
apex were triggering infinite resigning loops. This has
been fixed. [GL #2650]

5626. [bug] When generating zone signing keys, KASP now also checks
for key ID conflicts among newly created keys, rather
