names. (CVE-2023-4408) [GL #4234]

6314. [bug] Address race conditions in dns_tsigkey_find().
[GL #4182]

6312. [bug] Conversion from NSEC3 signed to NSEC signed could
temporarily put the zone into a state where it was
treated as unsigned until the NSEC chain was built.
Additionally conversion from one set of NSEC3 parameters
to another could also temporarily put the zone into a
state where it was treated as unsigned until the new
NSEC3 chain was built. [GL #1794] [GL #4495]

6310. [bug] Memory leak in zone.c:sign_zone. When named signed a
zone it could leak dst_keys due to a misplaced
'continue'. [GL #4488]

6306. [func] Log more details about the cause of "not exact" errors.
[GL #4500]

6304. [bug] The wrong time was being used to determine what RRSIGs
where to be generated when dnssec-policy was in use.
[GL #4494]

6302. [func] The "trust-anchor-telemetry" statement is no longer
marked as experimental. This silences a relevant log
message that was emitted even when the feature was
explicitly disabled. [GL #4497]

6300. [bug] Fix statistics export to use full 64 bit signed numbers
instead of truncating values to unsigned 32 bits.
[GL #4467]

6299. [port] NetBSD has added 'hmac' to libc which collides with our
use of 'hmac'. [GL #4478]

--- 9.18.21 released ---

6297. [bug] Improve LRU cleaning behaviour. [GL #4448]

6296. [func] The "resolver-nonbackoff-tries" and
"resolver-retry-interval" options are deprecated;
a warning will be logged if they are used. [GL #4405]

6294. [bug] BIND might sometimes crash after startup or
re-configuration when one 'tls' entry is used multiple
times to connect to remote servers due to initialisation
attempts from contexts of multiple threads. That has
been fixed. [GL #4464]

6290. [bug] Dig +yaml will now report "no servers could be reached"
also for UDP setup failure when no other servers or
tries are left. [GL #1229]

6287. [bug] Recognize escapes when reading the public key from file.
[GL !8502]

option together -X argument to named. [GL #4386]

6274. [bug] The 'lock-file' file was being removed when it
shouldn't have been making it ineffective if named was
started 3 or more times. [GL #4387]

6271. [bug] Fix a shutdown race in dns__catz_update_cb(). [GL #4381]

6269. [maint] B.ROOT-SERVERS.NET addresses are now 170.247.170.2 and
2801:1b8:10::b. [GL #4101]

6267. [func] The timeouts for resending zone refresh queries over UDP
were lowered to enable named to more quickly determine
that a primary is down. [GL #4260]

6265. [bug] Don't schedule resign operations on the raw version
of an inline-signing zone. [GL #4350]

6261. [bug] Fix a possible assertion failure on an error path in
resolver.c:fctx_query(), when using an uninitialized
link. [GL #4331]

6254. [cleanup] Add semantic patch to do an explicit cast from char
to unsigned char in ctype.h class of functions.
[GL #4327]

6252. [test] Python system tests have to be executed by invoking
pytest directly. Executing them with the legacy test
runner is no longer supported. [GL #4250]

6250. [bug] The wrong covered value was being set by
dns_ncache_current for RRSIG records in the returned
rdataset structure. This resulted in TYPE0 being
reported as the covered value of the RRSIG when dumping
the cache contents. [GL #4314]

--- 9.18.19 released ---

6246. [security] Fix use-after-free error in TLS DNS code when sending
data. (CVE-2023-4236) [GL #4242]

6245. [security] Limit the amount of recursion that can be performed
by isccc_cc_fromwire. (CVE-2023-3341) [GL #4152]

6244. [bug] Adjust log levels on malformed messages to NOTICE when
transferring in a zone. [GL #4290]

6241. [bug] Take into account the possibility of partial TLS writes
in TLS DNS code. That helps to prevent DNS messages
corruption on long DNS over TLS streams. [GL #4255]

6240. [bug] Use dedicated per-worker thread jemalloc memory
arenas for send buffers allocation to reduce memory
consumption and avoid lock contention. [GL #4038]

6239. [func] Deprecate the 'dnssec-must-be-secure' option.
[GL #3700]

6206. [bug] Add shutdown checks in dns_catz_dbupdate_callback() to
avoid a race with dns_catz_shutdown_catzs(). [GL #4171]

6205. [bug] Restore support to read legacy HMAC-MD5 K file pairs.
[GL #4154]

6204. [bug] Use NS records for relaxed QNAME-minimization mode.
This reduces the number of queries named makes when
resolving, as it allows the non-existence of NS RRsets
at non-referral nodes to be cached in addition to the
referrals that are normally cached. [GL #3325]

6200. [bug] Fix nslookup erroneously reporting a timeout when the
input is delayed. [GL #4044]

6199. [bug] Improve HTTP Connection: header protocol conformance
in the statistics channel. [GL #4126]

6198. [func] Remove the holes in the isc_result_t enum to compact
the isc_result tables. [GL #4149]

update notification callback for a catalog zone.
[GL #4132]

6196. [cleanup] Report "permission denied" instead of "unexpected error"
when trying to update a zone file on a read-only file
system. Thanks to Midnight Veil. [GL #4134]

6193. [bug] Fix a catz db update notification callback registration
logic error, which could crash named when receiving an
AXFR update for a catalog zone while the previous update
process of the catalog zone was already running.
[GL #4136]

6166. [func] Retry without DNS COOKIE on FORMERR if it appears that
the FORMERR was due to the presence of a DNS COOKIE
option. [GL #4049]

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]

--- 9.16.3 released ---

5404. [bug] 'named-checkconf -z' could incorrectly indicate
success if errors were found in one view but not in a
subsequent one. [GL #1807]

5403. [func] Do not set UDP receive/send buffer sizes - use system
defaults. [GL #1713]

5402. [bug] On FreeBSD, use SO_REUSEPORT_LB instead of SO_REUSEPORT.
Enable use of SO_REUSEADDR on all platforms which
support it. [GL !3365]

5401. [bug] The number of input queues allocated during dnstap
initialization was too low, which could prevent some
dnstap data from being logged. [GL #1795]

5400. [func] Add engine support to OpenSSL EdDSA implementation.
[GL #1763]

5399. [func] Add engine support to OpenSSL ECDSA implementation.
[GL #1534]

5398. [bug] Named could fail to restart if a zone with a double
quote (") in its name was added with 'rndc addzone'.
[GL #1695]

5397. [func] Update PKCS#11 EdDSA implementation to PKCS#11 v3.0.
Thanks to Aaron Thompson. [GL !3326]

5396. [func] When necessary (i.e. in libuv >= 1.37), use the
UV_UDP_RECVMMSG flag to enable recvmmsg() support in
libuv. [GL #1797]

5395. [security] Further limit the number of queries that can be
triggered from a request. Root and TLD servers
are no longer exempt from max-recursion-queries.
Fetches for missing name server address records
are limited to 4 for any domain. (CVE-2020-8616)
[GL #1388]

5394. [cleanup] Named formerly attempted to change the effective UID and
GID in named_os_openfile(), which could trigger a
spurious log message if they were already set to the
desired values. This has been fixed. [GL #1042]
[GL #1090]

5392. [bug] It was possible for named to crash during shutdown
or reconfiguration if an RPZ zone was still being
updated. [GL #1779]

5390. [security] Replaying a TSIG BADTIME response as a request could
trigger an assertion failure. (CVE-2020-8617)
[GL #1703]

5389. [bug] Finish PKCS#11 code cleanup, fix a couple of smaller
bugs and use PKCS#11 v3.0 EdDSA macros and constants.
Thanks to Aaron Thompson. [GL !3391]

5387. [func] Warn about AXFR streams with inconsistent message IDs.
[GL #1674]

5386. [cleanup] Address Coverity warnings in lib/dns/keymgr.c.
[GL #1737]

5385. [func] Make ISC rwlock implementation the default again.
[GL #1753]

5384. [bug] With "dnssec-policy" in effect, "inline-signing" was
implicitly set to "yes". Now "inline-signing" is only
set to "yes" if the zone is not dynamic. [GL #1709]

--- 9.16.2 released ---

5383. [func] Add a quota attach function with a callback and clean up
the isc_quota API. [GL !3280]

5382. [bug] Use clock_gettime() instead of gettimeofday() for
isc_stdtime() function. [GL #1679]

5381. [bug] Fix logging API data race by adding rwlock and caching
logging levels in stdatomic variables to restore
performance to original levels. [GL #1675] [GL #1717]

5380. [contrib] Fix building MySQL DLZ modules against MySQL 8
libraries. [GL #1678]

5378. [bug] Receiving invalid DNS data was triggering an assertion
failure in nslookup. [GL #1652]

5376. [bug] Fix ineffective DNS rebinding protection when BIND is
configured as a forwarding DNS server. Thanks to Tobias
Klein. [GL #1574]

5375. [test] Fix timing issues in the "kasp" system test. [GL #1669]

5374. [bug] Statistics counters tracking recursive clients and
active connections could underflow. [GL #1087]

5373. [bug] Collecting statistics for DNSSEC signing operations
(change 5254) caused an array of significant size (over
100 kB) to be allocated for each configured zone. Each
of these arrays is tracking all possible key IDs; this
could trigger an out-of-memory condition on servers with
a high enough number of zones configured. Fixed by
tracking up to four keys per zone and rotating counters
when keys are replaced. This fixes the immediate problem
of high memory usage, but should be improved in a future
release by growing or shrinking the number of keys to
track upon key rollover events. [GL #1179]

5372. [bug] Fix migration from existing DNSSEC key files
("auto-dnssec maintain") to "dnssec-policy". [GL #1706]

5371. [bug] Improve incremental updates of the RPZ summary
database to reduce delays that could occur when
a policy zone update included a large number of
record deletions. [GL #1447]

5370. [bug] Deactivation of a netmgr handle associated with a
socket could be skipped in some circumstances.
Fixed by deactivating the netmgr handle before
scheduling the asynchronous close routine. [GL #1700]

5368. [bug] Named failed to restart if 'rndc addzone' names
contained special characters (e.g. '/'). [GL #1655]

5367. [bug] Fixed a flaw in the calculation of the zone database
size so that "max-journal-size default" uses the correct
limit. [GL #1661]

--- 9.16.1 released ---

5366. [bug] Fix a race condition with the keymgr when the same
zone plus dnssec-policy is configured in multiple
views. [GL #1653]

5365. [bug] Algorithm rollover was stuck on submitting DS
because keymgr thought it would move to an invalid
state. Fixed by checking the current key against
the desired state, not the existing state. [GL #1626]

5364. [bug] Algorithm rollover waited too long before introducing
zone signatures. It waited to make sure all signatures
were regenerated, but when introducing a new algorithm,
all signatures are regenerated immediately. Only
add the sign delay if there is a predecessor key.
[GL #1625]

5363. [bug] When changing a dnssec-policy, existing keys with
properties that no longer match were not being retired.
[GL #1624]

5361. [bug] named might not accept new connections after
hitting tcp-clients quota. [GL #1643]

5360. [bug] delv could fail to load trust anchors in DNSKEY
format. [GL #1647]

5358. [bug] Inline master zones whose master files were touched
but otherwise unchanged and were subsequently reloaded
may have stopped re-signing. [GL !3135]

5357. [bug] Newly added RRSIG records with expiry times before
the previous earliest expiry times might not be
re-signed in time. This was a side effect of 5315.
[GL !3137]

--- 9.16.0 released ---

5356. [func] Update dnssec-policy configuration statements:
- Rename "zone-max-ttl" dnssec-policy option to
"max-zone-ttl" for consistency with the existing
zone option.
- Allow for "lifetime unlimited" as a synonym for
"lifetime PT0S".
- Make "key-directory" optional.
- Warn if specifying a key length does not make
sense; fail if key length is out of range for
the algorithm.
- Allow use of mnemonics when specifying key
algorithm (e.g. "rsasha256", "ecdsa384", etc.).
- Make ISO 8601 durations case-insensitive.
[GL #1598]

5355. [func] What was set with --with-tuning=large option in
older BIND9 versions is now a default, and
a --with-tuning=small option was added for small
(e.g. OpenWRT) systems. [GL !2989]

5354. [bug] dnssec-policy created new KSK keys for zones in the
initial stage of signing (with the DS not yet in the
rumoured or omnipresent states). Fix by checking the
key goals rather than the active state when determining
whether new keys are needed. [GL #1593]

5353. [doc] Document port and dscp parameters in forwarders
configuration option. [GL #914]

5352. [bug] Correctly handle catalog zone entries containing
characters that aren't legal in filenames. [GL #1592]

5351. [bug] CDS / CDNSKEY consistency checks failed to handle
removal records. [GL #1554]

5350. [bug] When a view was configured with class CHAOS, the
server could crash while processing a query for a
non-existent record. [GL #1540]

5349. [bug] Fix a race in task_pause/unpause. [GL #1571]

5348. [bug] dnssec-settime -Psync was not being honoured.
[GL !2925]

--- 9.15.8 released ---

5347. [bug] Fixed a bug that could cause an intermittent crash
in validator.c when validating a negative cache
entry. [GL #1561]

5346. [bug] Make hazard pointer array allocations dynamic, fixing
a bug that caused named to crash on machines with more
than 40 cores. [GL #1493]

5345. [func] Key-style trust anchors and DS-style trust anchors
can now both be used for the same name. [GL #1237]

5344. [bug] Handle accept() errors properly in netmgr. [GL !2880]

5343. [func] Add statistics counters to the netmgr. [GL #1311]

5342. [bug] Disable pktinfo for IPv6 and bind to each interface
explicitly instead, because libuv doesn't support
pktinfo control messages. [GL #1558]

5341. [func] Simplify passing the bound TCP socket to child
threads by using isc_uv_export/import functions.
[GL !2825]

5340. [bug] Don't deadlock when binding to a TCP socket fails.
[GL #1499]

5339. [bug] With some libmaxminddb versions, named could erroneously
match an IP address not belonging to any subnet defined
in a given GeoIP2 database to one of the existing
entries in that database. [GL #1552]

5338. [bug] Fix line spacing in `rndc secroots`.
Thanks to Tony Finch. [GL !2478]

5337. [func] 'named -V' now reports maxminddb and protobuf-c
versions. [GL !2686]

--- 9.15.7 released ---

5336. [bug] The TCP high-water statistic could report an
incorrect value on startup. [GL #1392]

5335. [func] Make TCP listening code multithreaded. [GL !2659]

5334. [doc] Update documentation with dnssec-policy clarifications.
Also change some defaults. [GL !2711]

5333. [bug] Fix duration printing on Solaris when value is not
an ISO 8601 duration. [GL #1460]

5332. [func] Renamed "dnssec-keys" configuration statement
to the more descriptive "trust-anchors". [GL !2702]

5331. [func] Use compiler-provided mechanisms for thread local
storage, and make the requirement for such mechanisms
explicit in configure. [GL #1444]

5330. [bug] 'configure --without-python' was ineffective if
PYTHON was set in the environment. [GL #1434]

5329. [bug] Reconfiguring named caused memory to be leaked when any
GeoIP2 database was in use. [GL #1445]

5328. [bug] rbtdb.c:rdataset_{get,set}ownercase failed to obtain
a node lock. [GL #1417]

5327. [func] Added a statistics counter to track queries
dropped because the recursive-clients quota was
exceeded. [GL #1399]

5326. [bug] Add Python dependency on 'distutils.core' to configure.
'distutils.core' is required for installation.
[GL #1397]

5325. [bug] Addressed several issues with TCP connections in
the netmgr: restored support for TCP connection
timeouts, restored TCP backlog support, actively
close all open sockets during shutdown. [GL #1312]

5324. [bug] Change the category of some log messages from general
to the more appropriate catergory of xfer-in. [GL #1394]

5323. [bug] Fix a bug in DNSSEC trust anchor verification.
[GL !2609]

5322. [placeholder]

5321. [bug] Obtain write lock before updating version->records
and version->bytes. [GL #1341]

5320. [cleanup] Silence TSAN on header->count. [GL #1344]

--- 9.15.6 released ---

5319. [func] Trust anchors can now be configured using DS
format to represent a key digest, by using the
new "initial-ds" or "static-ds" keywords in
the "dnssec-keys" statement.

Note: DNSKEY-format and DS-format trust anchors
cannot both be used for the same domain name.
[GL #622]

5318. [cleanup] The DNSSEC validation code has been refactored
for clarity and to reduce code duplication.
[GL #622]

5317. [func] A new asynchronous network communications system
based on libuv is now used for listening for
incoming requests and responding to them. (The
old isc_socket API remains in use for sending
iterative queries and processing responses; this
will be changed too in a later release.)

This change will make it easier to improve
performance and implement new protocol layers
(e.g., DNS over TLS) in the future. [GL #29]

5316. [func] A new "dnssec-policy" option has been added to
named.conf to implement a key and signing policy
(KASP) for zones. When this option is in use,
named can generate new keys as needed and
automatically roll both ZSK and KSK keys. (Note
that the syntax for this statement differs from
the dnssec policy used by dnssec-keymgr.)

See the ARM for configuration details. [GL #1134]

5315. [bug] Apply the initial RRSIG expiration spread fixed
to all dynamically created records in the zone
including NSEC3. Also fix the signature clusters
when the server has been offline for prolonged
period of times. [GL #1256]

5314. [func] Added a new statistics variable "tcp-highwater"
that reports the maximum number of simultaneous TCP
clients BIND has handled while running. [GL #1206]

5313. [bug] The default GeoIP2 database location did not match
the ARM. 'named -V' now reports the default
location. [GL #1301]

5312. [bug] Do not flush the cache for `rndc validation status`.
Thanks to Tony Finch. [GL !2462]

5311. [cleanup] Include all views in output of `rndc validation status`.
Thanks to Tony Finch. [GL !2461]

5310. [bug] TCP failures were affecting EDNS statistics. [GL #1059]

5309. [placeholder]

5308. [bug] Don't log DNS_R_UNCHANGED from sync_secure_journal()
at ERROR level in receive_secure_serial(). [GL #1288]

5307. [bug] Fix hang when named-compilezone output is sent to pipe.
Thanks to Tony Finch. [GL !2481]

5306. [security] Set a limit on number of simultaneous pipelined TCP
queries. (CVE-2019-6477) [GL #1264]

5305. [bug] NSEC Aggressive Cache ("synth-from-dnssec") has been
disabled by default because it was found to have
a significant performance impact on the recursive
service. [GL #1265]

5304. [bug] "dnskey-sig-validity 0;" was not being accepted.
[GL #876]

5303. [placeholder]

5302. [bug] Fix checking that "dnstap-output" is defined when
"dnstap" is specified in a view. [GL #1281]

5301. [bug] Detect partial prefixes / incomplete IPv4 address in
acls. [GL #1143]

5300. [bug] dig/mdig/delv: Add a colon after EDNS option names,
even when the option is empty, to improve
readability and allow correct parsing of YAML
output. [GL #1226]

--- 9.15.5 released ---

5299. [security] A flaw in DNSSEC verification when transferring
mirror zones could allow data to be incorrectly
marked valid. (CVE-2019-6475) [GL #1252]

5298. [security] Named could assert if a forwarder returned a
referral, rather than resolving the query, when QNAME
minimization was enabled. (CVE-2019-6476) [GL #1051]

5297. [bug] Check whether a previous QNAME minimization fetch
is still running before starting a new one; return
SERVFAIL and log an error if so. [GL #1191]

5296. [placeholder]

5295. [cleanup] Split dns_name_copy() calls into dns_name_copy() and
dns_name_copynf() for those calls that can potentially
fail and those that should not fail respectively.
[GL !2265]

5294. [func] Fallback to ACE name on output in locale, which does not
support converting it to unicode. [GL #846]

5293. [bug] On Windows, named crashed upon any attempt to fetch XML
statistics from it. [GL #1245]

5292. [bug] Queue 'rndc nsec3param' requests while signing inline
zone changes. [GL #1205]

dlz_mysqldyn_mod.c. [GL #1207]

5285. [port] win32: implement "-T maxudpXXX". [GL #837]

5284. [func] Added +unexpected command line option to dig.
By default, dig won't accept a reply from a source
other than the one to which it sent the query.
Invoking dig with +unexpected argument will allow it
to process replies from unexpected sources.

5283. [bug] When a response-policy zone expires, ensure that
its policies are removed from the RPZ summary
database. [GL #1146]

5282. [bug] Fixed a bug in searching for possible wildcard matches
for query names in the RPZ summary database. [GL #1146]

5281. [cleanup] Don't escape commas when reporting named's command
line. [GL #1189]

5280. [protocol] Add support for displaying EDNS option LLQ. [GL #1201]

5279. [bug] When loading, reject zones containing CDS or CDNSKEY
RRsets at the zone apex if they would cause DNSSEC
validation failures if published in the parent zone
as the DS RRset. [GL #1187]

5278. [func] Add YAML output formats for dig, mdig and delv;
use the "+yaml" option to enable. [GL #1145]

--- 9.15.3 released ---

5277. [bug] Cache DB statistics could underflow when serve-stale
was in use, because of a bug in counter maintenance
when RRsets become stale.

Functions for dumping statistics have been updated
to dump active, stale, and ancient statistic
counters. Ancient RRset counters are prefixed
with '~'; stale RRset counters are still prefixed
with '#'. [GL #602]

5276. [func] DNSSEC Lookaside Validation (DLV) is now obsolete;
all code enabling its use has been removed from the
validator, "delv", and the DNSSEC tools. [GL #7]

5275. [bug] Mark DS records included in referral messages
with trust level "pending" so that they can be
validated and cached immediately, with no need to
re-query. [GL #964]

5274. [bug] Address potential use after free race when shutting
down rpz. [GL #1175]

5273. [bug] Check that bits [64..71] of a dns64 prefix are zero.
[GL #1159]

5272. [cleanup] Remove isc-config.sh script as the BIND 9 libraries
are now purely internal. [GL #1123]

5271. [func] The normal (non-debugging) output of dnssec-signzone
and dnssec-verify tools now goes to stdout, instead of
the combination of stderr and stdout.

5270. [bug] 'dig +expandaaaa +short' did not work. [GL #1152]

5269. [port] cygwin: can return ETIMEDOUT on connect() with a
non-blocking socket. [GL #1133]

5268. [placeholder]

5267. [func] Allow statistics groups display to be toggle-able.
[GL #1030]

5266. [bug] named-checkconf failed to report dnstap-output
missing from named.conf when dnstap was specified.
[GL #1136]

5265. [bug] DNS64 and RPZ nodata (CNAME *.) rules interacted badly
[GL #1106]

5264. [func] New DNS Cookie algorithm - siphash24 - has been added
to BIND 9, and the old HMAC-SHA DNS Cookie algorithms
have been removed. [GL #605]

--- 9.15.2 released ---

5263. [cleanup] Use atomics and isc_refcount_t wherever possible.
[GL #1038]

5262. [func] Removed support for the legacy GeoIP API. [GL #1112]

5261. [cleanup] Remove SO_BSDCOMPAT socket option usage.

5260. [bug] dnstap-read was producing malformed output for large
packets. [GL #1093]

5259. [func] New option '-i' for 'named-checkconf' to ignore
warnings about deprecated options. [GL #1101]

5258. [func] Added support for the GeoIP2 API from MaxMind. This
will be compiled in by default if the "libmaxminddb"
library is found at compile time, but can be
suppressed using "configure --disable-geoip".

Certain geoip ACL settings that were available with
legacy GeoIP are not available when using GeoIP2.
[GL #182]

5257. [bug] Some statistics data was not being displayed.
Add shading to the zone tables. [GL #1030]

5256. [bug] Ensure that glue records are included in root
priming responses if "minimal-responses" is not
set to "yes". [GL #1092]

5255. [bug] Errors encountered while reloading inline-signing
zones could be ignored, causing the zone content to
be left in an incompletely updated state rather than
reverted. [GL #1109]

5254. [func] Collect metrics to report to the statistics-channel
DNSSEC signing operations (dnssec-sign) and refresh
operations (dnssec-refresh) per zone and per keytag.
[GL #513]

5253. [port] Support platforms that don't define ULLONG_MAX.
[GL #1098]

5252. [func] Report if the last 'rndc reload/reconfig' failed in
rndc status. [GL !2040]

5251. [bug] Statistics were broken in x86 Windows builds.
[GL #1081]

5250. [func] The default size for RSA keys is now 2048 bits,
for both ZSKs and KSKs. [GL #1097]

5249. [bug] Fix a possible underflow in recursion clients
statistics when hitting recursive clients
soft quota. [GL #1067]

--- 9.15.1 released ---

5248. [func] To clarify the configuration of DNSSEC keys,
the "managed-keys" and "trusted-keys" options
have both been deprecated. The new "dnssec-keys"
statement can now be used for all trust anchors,
with the keywords "iniital-key" or "static-key"
to indicate whether the configured trust anchor
should be used for initialization of RFC 5011 key
management, or as a permanent trust anchor.

The "static-key" keyword will generate a warning if
used for the root zone.

Configurations using "trusted-keys" or "managed-keys"
will continue to work with no changes, but will
generate warnings in the log. In a future release,
these options will be marked obsolete. [GL #6]

5247. [cleanup] The 'cleaning-interval' option has been removed.
[GL !1731]

5246. [func] Log TSIG if appropriate in 'sending notify to' message.
[GL #1058]

5245. [cleanup] Reduce logging level for IXFR up-to-date poll
responses. [GL #1009]

5244. [security] Fixed a race condition in dns_dispatch_getnext()
that could cause an assertion failure if a
significant number of incoming packets were
rejected. (CVE-2019-6471) [GL #942]

5243. [bug] Fix a possible race between dispatcher and socket
code in a high-load cold-cache resolver scenario.
[GL #943]

5242. [bug] In relaxed qname minimization mode, fall back to
normal resolution when encountering a lame

than domain/NS. [GL #1055]

5241. [bug] Fix Ed448 private and public key ASN.1 prefix blobs.
[GL #225]

and switch isc_hash_function() to use SipHash 2-4.
[GL #605]

5235. [cleanup] Refactor lib/isc/app.c to be thread-safe, unused
parts of the API has been removed and the
isc_appctx_t data type has been changed to be
fully opaque. [GL #1023]

5234. [port] arm: just use the compiler's default support for
yield. [GL #981]

--- 9.15.0 released ---

5233. [bug] Negative trust anchors did not work with "forward only;"
to validating resolvers. [GL #997]

5232. [placeholder]

5231. [protocol] Add support for displaying CLIENT-TAG and SERVER-TAG.
[GL #960]

5230. [protocol] The SHA-1 hash algorithm is no longer used when
generating DS and CDS records. [GL #1015]

5229. [protocol] Enforce known SSHFP fingerprint lengths. [GL #852]

5228. [func] If trusted-keys and managed-keys were configured
simultaneously for the same name, the key could
not be be rolled automatically. This is now
a fatal configuration error. [GL #868]

5227. [placeholder]

5226. [placeholder]

was inadvertently removed in change #4605. [GL #817]

5210. [bug] When dnstap is enabled and recursion is not
available, incoming queries are now logged
as "auth". Previously, this depended on whether
recursion was requested by the client, not on
whether recursion was available. [GL #963]

5209. [bug] When update-check-ksk is true, add_sigs was not
considering offline keys, leaving record sets signed

5172. [bug] nsupdate now honors the operating system's preferred
ephemeral port range. [GL #905]

5171. [func] named plugins are now installed into a separate
directory. Supplying a filename (a string without path
separators) in a "plugin" configuration stanza now
causes named to look for that plugin in that directory.
[GL #878]

5170. [test] Added --with-dlz-filesystem to feature-test. [GL !1587]

mirror zones. [GL #774]

5155. [func] "named -V" now outputs the default paths to
named.conf, rndc.conf, bind.keys, and other
files used or created by named and other tools, so
that the correct paths to these files can quickly be
determined regardless of the configure settings
used when BIND was built. [GL #859]

not effective as the allowzonexfr method was not being
called for such zones. (CVE-2019-6465) [GL #790]

5140. [bug] Don't immediately mark existing keys as inactive and
deleted when running dnssec-keymgr for the first
time. [GL #117]

5139. [bug] If possible, don't use forwarders when priming.
This ensures we can get root server IP addresses
from priming query response glue, which may not
be present if the forwarding server is returning
minimal responses. [GL #752]

5138. [bug] Under some circumstances named could hit an assertion
failure when doing qname minimization when using
forwarders. [GL #797]

5137. [func] named now logs messages whenever a mirror zone becomes
usable or unusable for resolution purposes. [GL #818]

5136. [cleanup] Check in named-checkconf that allow-update and

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

[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

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

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]

--- 9.16.3 released ---

5404. [bug] 'named-checkconf -z' could incorrectly indicate
success if errors were found in one view but not in a
subsequent one. [GL #1807]

5403. [func] Do not set UDP receive/send buffer sizes - use system
defaults. [GL #1713]

5402. [bug] On FreeBSD, use SO_REUSEPORT_LB instead of SO_REUSEPORT.
Enable use of SO_REUSEADDR on all platforms which
support it. [GL !3365]

5401. [bug] The number of input queues allocated during dnstap
initialization was too low, which could prevent some
dnstap data from being logged. [GL #1795]

5400. [func] Add engine support to OpenSSL EdDSA implementation.
[GL #1763]

5399. [func] Add engine support to OpenSSL ECDSA implementation.
[GL #1534]

5398. [bug] Named could fail to restart if a zone with a double
quote (") in its name was added with 'rndc addzone'.
[GL #1695]

5397. [func] Update PKCS#11 EdDSA implementation to PKCS#11 v3.0.
Thanks to Aaron Thompson. [GL !3326]

5396. [func] When necessary (i.e. in libuv >= 1.37), use the
UV_UDP_RECVMMSG flag to enable recvmmsg() support in
libuv. [GL #1797]

5395. [security] Further limit the number of queries that can be
triggered from a request. Root and TLD servers
are no longer exempt from max-recursion-queries.
Fetches for missing name server address records
are limited to 4 for any domain. (CVE-2020-8616)
[GL #1388]

5394. [cleanup] Named formerly attempted to change the effective UID and
GID in named_os_openfile(), which could trigger a
spurious log message if they were already set to the
desired values. This has been fixed. [GL #1042]
[GL #1090]

5392. [bug] It was possible for named to crash during shutdown
or reconfiguration if an RPZ zone was still being
updated. [GL #1779]

5390. [security] Replaying a TSIG BADTIME response as a request could
trigger an assertion failure. (CVE-2020-8617)
[GL #1703]

5389. [bug] Finish PKCS#11 code cleanup, fix a couple of smaller
bugs and use PKCS#11 v3.0 EdDSA macros and constants.
Thanks to Aaron Thompson. [GL !3391]

5387. [func] Warn about AXFR streams with inconsistent message IDs.
[GL #1674]

5386. [cleanup] Address Coverity warnings in lib/dns/keymgr.c.
[GL #1737]

5385. [func] Make ISC rwlock implementation the default again.
[GL #1753]

5384. [bug] With "dnssec-policy" in effect, "inline-signing" was
implicitly set to "yes". Now "inline-signing" is only
set to "yes" if the zone is not dynamic. [GL #1709]

--- 9.16.2 released ---

5383. [func] Add a quota attach function with a callback and clean up
the isc_quota API. [GL !3280]

5382. [bug] Use clock_gettime() instead of gettimeofday() for
isc_stdtime() function. [GL #1679]

5381. [bug] Fix logging API data race by adding rwlock and caching
logging levels in stdatomic variables to restore
performance to original levels. [GL #1675] [GL #1717]

5380. [contrib] Fix building MySQL DLZ modules against MySQL 8
libraries. [GL #1678]

5378. [bug] Receiving invalid DNS data was triggering an assertion
failure in nslookup. [GL #1652]

5376. [bug] Fix ineffective DNS rebinding protection when BIND is
configured as a forwarding DNS server. Thanks to Tobias
Klein. [GL #1574]

5375. [test] Fix timing issues in the "kasp" system test. [GL #1669]

5374. [bug] Statistics counters tracking recursive clients and
active connections could underflow. [GL #1087]

5373. [bug] Collecting statistics for DNSSEC signing operations
(change 5254) caused an array of significant size (over
100 kB) to be allocated for each configured zone. Each
of these arrays is tracking all possible key IDs; this
could trigger an out-of-memory condition on servers with
a high enough number of zones configured. Fixed by
tracking up to four keys per zone and rotating counters
when keys are replaced. This fixes the immediate problem
of high memory usage, but should be improved in a future
release by growing or shrinking the number of keys to
track upon key rollover events. [GL #1179]

5372. [bug] Fix migration from existing DNSSEC key files
("auto-dnssec maintain") to "dnssec-policy". [GL #1706]

5371. [bug] Improve incremental updates of the RPZ summary
database to reduce delays that could occur when
a policy zone update included a large number of
record deletions. [GL #1447]

5370. [bug] Deactivation of a netmgr handle associated with a
socket could be skipped in some circumstances.
Fixed by deactivating the netmgr handle before
scheduling the asynchronous close routine. [GL #1700]

5368. [bug] Named failed to restart if 'rndc addzone' names
contained special characters (e.g. '/'). [GL #1655]

5367. [bug] Fixed a flaw in the calculation of the zone database
size so that "max-journal-size default" uses the correct
limit. [GL #1661]

--- 9.16.1 released ---

5366. [bug] Fix a race condition with the keymgr when the same
zone plus dnssec-policy is configured in multiple
views. [GL #1653]

5365. [bug] Algorithm rollover was stuck on submitting DS
because keymgr thought it would move to an invalid
state. Fixed by checking the current key against
the desired state, not the existing state. [GL #1626]

5364. [bug] Algorithm rollover waited too long before introducing
zone signatures. It waited to make sure all signatures
were regenerated, but when introducing a new algorithm,
all signatures are regenerated immediately. Only
add the sign delay if there is a predecessor key.
[GL #1625]

5363. [bug] When changing a dnssec-policy, existing keys with
properties that no longer match were not being retired.
[GL #1624]

5361. [bug] named might not accept new connections after
hitting tcp-clients quota. [GL #1643]

5360. [bug] delv could fail to load trust anchors in DNSKEY
format. [GL #1647]

5358. [bug] Inline master zones whose master files were touched
but otherwise unchanged and were subsequently reloaded
may have stopped re-signing. [GL !3135]

5357. [bug] Newly added RRSIG records with expiry times before
the previous earliest expiry times might not be
re-signed in time. This was a side effect of 5315.
[GL !3137]

--- 9.16.0 released ---

5356. [func] Update dnssec-policy configuration statements:
- Rename "zone-max-ttl" dnssec-policy option to
"max-zone-ttl" for consistency with the existing
zone option.
- Allow for "lifetime unlimited" as a synonym for
"lifetime PT0S".
- Make "key-directory" optional.
- Warn if specifying a key length does not make
sense; fail if key length is out of range for
the algorithm.
- Allow use of mnemonics when specifying key
algorithm (e.g. "rsasha256", "ecdsa384", etc.).
- Make ISO 8601 durations case-insensitive.
[GL #1598]

5355. [func] What was set with --with-tuning=large option in
older BIND9 versions is now a default, and
a --with-tuning=small option was added for small
(e.g. OpenWRT) systems. [GL !2989]

5354. [bug] dnssec-policy created new KSK keys for zones in the
initial stage of signing (with the DS not yet in the
rumoured or omnipresent states). Fix by checking the
key goals rather than the active state when determining
whether new keys are needed. [GL #1593]

5353. [doc] Document port and dscp parameters in forwarders
configuration option. [GL #914]

5352. [bug] Correctly handle catalog zone entries containing
characters that aren't legal in filenames. [GL #1592]

5351. [bug] CDS / CDNSKEY consistency checks failed to handle
removal records. [GL #1554]

5350. [bug] When a view was configured with class CHAOS, the
server could crash while processing a query for a
non-existent record. [GL #1540]

5349. [bug] Fix a race in task_pause/unpause. [GL #1571]

5348. [bug] dnssec-settime -Psync was not being honoured.
[GL !2925]

--- 9.15.8 released ---

5347. [bug] Fixed a bug that could cause an intermittent crash
in validator.c when validating a negative cache
entry. [GL #1561]

5346. [bug] Make hazard pointer array allocations dynamic, fixing
a bug that caused named to crash on machines with more
than 40 cores. [GL #1493]

5345. [func] Key-style trust anchors and DS-style trust anchors
can now both be used for the same name. [GL #1237]

5344. [bug] Handle accept() errors properly in netmgr. [GL !2880]

5343. [func] Add statistics counters to the netmgr. [GL #1311]

5342. [bug] Disable pktinfo for IPv6 and bind to each interface
explicitly instead, because libuv doesn't support
pktinfo control messages. [GL #1558]

5341. [func] Simplify passing the bound TCP socket to child
threads by using isc_uv_export/import functions.
[GL !2825]

5340. [bug] Don't deadlock when binding to a TCP socket fails.
[GL #1499]

5339. [bug] With some libmaxminddb versions, named could erroneously
match an IP address not belonging to any subnet defined
in a given GeoIP2 database to one of the existing
entries in that database. [GL #1552]

5338. [bug] Fix line spacing in `rndc secroots`.
Thanks to Tony Finch. [GL !2478]

5337. [func] 'named -V' now reports maxminddb and protobuf-c
versions. [GL !2686]

--- 9.15.7 released ---

5336. [bug] The TCP high-water statistic could report an
incorrect value on startup. [GL #1392]

5335. [func] Make TCP listening code multithreaded. [GL !2659]

5334. [doc] Update documentation with dnssec-policy clarifications.
Also change some defaults. [GL !2711]

5333. [bug] Fix duration printing on Solaris when value is not
an ISO 8601 duration. [GL #1460]

5332. [func] Renamed "dnssec-keys" configuration statement
to the more descriptive "trust-anchors". [GL !2702]

5331. [func] Use compiler-provided mechanisms for thread local
storage, and make the requirement for such mechanisms
explicit in configure. [GL #1444]

5330. [bug] 'configure --without-python' was ineffective if
PYTHON was set in the environment. [GL #1434]

5329. [bug] Reconfiguring named caused memory to be leaked when any
GeoIP2 database was in use. [GL #1445]

5328. [bug] rbtdb.c:rdataset_{get,set}ownercase failed to obtain
a node lock. [GL #1417]

5327. [func] Added a statistics counter to track queries
dropped because the recursive-clients quota was
exceeded. [GL #1399]

5326. [bug] Add Python dependency on 'distutils.core' to configure.
'distutils.core' is required for installation.
[GL #1397]

5325. [bug] Addressed several issues with TCP connections in
the netmgr: restored support for TCP connection
timeouts, restored TCP backlog support, actively
close all open sockets during shutdown. [GL #1312]

5324. [bug] Change the category of some log messages from general
to the more appropriate catergory of xfer-in. [GL #1394]

5323. [bug] Fix a bug in DNSSEC trust anchor verification.
[GL !2609]

5322. [placeholder]

5321. [bug] Obtain write lock before updating version->records
and version->bytes. [GL #1341]

5320. [cleanup] Silence TSAN on header->count. [GL #1344]

--- 9.15.6 released ---

5319. [func] Trust anchors can now be configured using DS
format to represent a key digest, by using the
new "initial-ds" or "static-ds" keywords in
the "dnssec-keys" statement.

Note: DNSKEY-format and DS-format trust anchors
cannot both be used for the same domain name.
[GL #622]

5318. [cleanup] The DNSSEC validation code has been refactored
for clarity and to reduce code duplication.
[GL #622]

5317. [func] A new asynchronous network communications system
based on libuv is now used for listening for
incoming requests and responding to them. (The
old isc_socket API remains in use for sending
iterative queries and processing responses; this
will be changed too in a later release.)

This change will make it easier to improve
performance and implement new protocol layers
(e.g., DNS over TLS) in the future. [GL #29]

5316. [func] A new "dnssec-policy" option has been added to
named.conf to implement a key and signing policy
(KASP) for zones. When this option is in use,
named can generate new keys as needed and
automatically roll both ZSK and KSK keys. (Note
that the syntax for this statement differs from
the dnssec policy used by dnssec-keymgr.)

See the ARM for configuration details. [GL #1134]

5315. [bug] Apply the initial RRSIG expiration spread fixed
to all dynamically created records in the zone
including NSEC3. Also fix the signature clusters
when the server has been offline for prolonged
period of times. [GL #1256]

5314. [func] Added a new statistics variable "tcp-highwater"
that reports the maximum number of simultaneous TCP
clients BIND has handled while running. [GL #1206]

5313. [bug] The default GeoIP2 database location did not match
the ARM. 'named -V' now reports the default
location. [GL #1301]

5312. [bug] Do not flush the cache for `rndc validation status`.
Thanks to Tony Finch. [GL !2462]

5311. [cleanup] Include all views in output of `rndc validation status`.
Thanks to Tony Finch. [GL !2461]

5310. [bug] TCP failures were affecting EDNS statistics. [GL #1059]

5309. [placeholder]

5308. [bug] Don't log DNS_R_UNCHANGED from sync_secure_journal()
at ERROR level in receive_secure_serial(). [GL #1288]

5307. [bug] Fix hang when named-compilezone output is sent to pipe.
Thanks to Tony Finch. [GL !2481]

5306. [security] Set a limit on number of simultaneous pipelined TCP
queries. (CVE-2019-6477) [GL #1264]

5305. [bug] NSEC Aggressive Cache ("synth-from-dnssec") has been
disabled by default because it was found to have
a significant performance impact on the recursive
service. [GL #1265]

5304. [bug] "dnskey-sig-validity 0;" was not being accepted.
[GL #876]

5303. [placeholder]

5302. [bug] Fix checking that "dnstap-output" is defined when
"dnstap" is specified in a view. [GL #1281]

5301. [bug] Detect partial prefixes / incomplete IPv4 address in
acls. [GL #1143]

5300. [bug] dig/mdig/delv: Add a colon after EDNS option names,
even when the option is empty, to improve
readability and allow correct parsing of YAML
output. [GL #1226]

--- 9.15.5 released ---

5299. [security] A flaw in DNSSEC verification when transferring
mirror zones could allow data to be incorrectly
marked valid. (CVE-2019-6475) [GL #1252]

5298. [security] Named could assert if a forwarder returned a
referral, rather than resolving the query, when QNAME
minimization was enabled. (CVE-2019-6476) [GL #1051]

5297. [bug] Check whether a previous QNAME minimization fetch
is still running before starting a new one; return
SERVFAIL and log an error if so. [GL #1191]

5296. [placeholder]

5295. [cleanup] Split dns_name_copy() calls into dns_name_copy() and
dns_name_copynf() for those calls that can potentially
fail and those that should not fail respectively.
[GL !2265]

5294. [func] Fallback to ACE name on output in locale, which does not
support converting it to unicode. [GL #846]

5293. [bug] On Windows, named crashed upon any attempt to fetch XML
statistics from it. [GL #1245]

5292. [bug] Queue 'rndc nsec3param' requests while signing inline
zone changes. [GL #1205]

--- 9.15.4 released ---

[GL #1209]

5287. [placeholder]

5286. [contrib] Address potential NULL pointer dereferences in
dlz_mysqldyn_mod.c. [GL #1207]

5285. [port] win32: implement "-T maxudpXXX". [GL #837]

5284. [func] Added +unexpected command line option to dig.
By default, dig won't accept a reply from a source
other than the one to which it sent the query.
Invoking dig with +unexpected argument will allow it
to process replies from unexpected sources.

5283. [bug] When a response-policy zone expires, ensure that
its policies are removed from the RPZ summary
database. [GL #1146]

5282. [bug] Fixed a bug in searching for possible wildcard matches
for query names in the RPZ summary database. [GL #1146]

5281. [cleanup] Don't escape commas when reporting named's command
line. [GL #1189]

5280. [protocol] Add support for displaying EDNS option LLQ. [GL #1201]

5279. [bug] When loading, reject zones containing CDS or CDNSKEY
RRsets at the zone apex if they would cause DNSSEC
validation failures if published in the parent zone
as the DS RRset. [GL #1187]

5278. [func] Add YAML output formats for dig, mdig and delv;
use the "+yaml" option to enable. [GL #1145]

--- 9.15.3 released ---

5277. [bug] Cache DB statistics could underflow when serve-stale
was in use, because of a bug in counter maintenance
when RRsets become stale.

Functions for dumping statistics have been updated
to dump active, stale, and ancient statistic
counters. Ancient RRset counters are prefixed
with '~'; stale RRset counters are still prefixed
with '#'. [GL #602]

5276. [func] DNSSEC Lookaside Validation (DLV) is now obsolete;
all code enabling its use has been removed from the
validator, "delv", and the DNSSEC tools. [GL #7]

5275. [bug] Mark DS records included in referral messages
with trust level "pending" so that they can be
validated and cached immediately, with no need to
re-query. [GL #964]

5274. [bug] Address potential use after free race when shutting
down rpz. [GL #1175]

5273. [bug] Check that bits [64..71] of a dns64 prefix are zero.
[GL #1159]

5272. [cleanup] Remove isc-config.sh script as the BIND 9 libraries
are now purely internal. [GL #1123]

5271. [func] The normal (non-debugging) output of dnssec-signzone
and dnssec-verify tools now goes to stdout, instead of
the combination of stderr and stdout.

5270. [bug] 'dig +expandaaaa +short' did not work. [GL #1152]

5269. [port] cygwin: can return ETIMEDOUT on connect() with a
non-blocking socket. [GL #1133]

5268. [placeholder]

5267. [func] Allow statistics groups display to be toggle-able.
[GL #1030]

5266. [bug] named-checkconf failed to report dnstap-output
missing from named.conf when dnstap was specified.
[GL #1136]

5265. [bug] DNS64 and RPZ nodata (CNAME *.) rules interacted badly
[GL #1106]

5264. [func] New DNS Cookie algorithm - siphash24 - has been added
to BIND 9, and the old HMAC-SHA DNS Cookie algorithms
have been removed. [GL #605]

--- 9.15.2 released ---

5263. [cleanup] Use atomics and isc_refcount_t wherever possible.
[GL #1038]

5262. [func] Removed support for the legacy GeoIP API. [GL #1112]

5261. [cleanup] Remove SO_BSDCOMPAT socket option usage.

5260. [bug] dnstap-read was producing malformed output for large
packets. [GL #1093]

5259. [func] New option '-i' for 'named-checkconf' to ignore
warnings about deprecated options. [GL #1101]

5258. [func] Added support for the GeoIP2 API from MaxMind. This
will be compiled in by default if the "libmaxminddb"
library is found at compile time, but can be
suppressed using "configure --disable-geoip".

Certain geoip ACL settings that were available with
legacy GeoIP are not available when using GeoIP2.
[GL #182]

5257. [bug] Some statistics data was not being displayed.
Add shading to the zone tables. [GL #1030]

5256. [bug] Ensure that glue records are included in root
priming responses if "minimal-responses" is not
set to "yes". [GL #1092]

5255. [bug] Errors encountered while reloading inline-signing
zones could be ignored, causing the zone content to
be left in an incompletely updated state rather than
reverted. [GL #1109]

5254. [func] Collect metrics to report to the statistics-channel
DNSSEC signing operations (dnssec-sign) and refresh
operations (dnssec-refresh) per zone and per keytag.
[GL #513]

5253. [port] Support platforms that don't define ULLONG_MAX.
[GL #1098]

5252. [func] Report if the last 'rndc reload/reconfig' failed in

for both ZSKs and KSKs. [GL #1097]

5249. [bug] Fix a possible underflow in recursion clients
statistics when hitting recursive clients
soft quota. [GL #1067]

--- 9.15.1 released ---

5248. [func] To clarify the configuration of DNSSEC keys,
the "managed-keys" and "trusted-keys" options
have both been deprecated. The new "dnssec-keys"
statement can now be used for all trust anchors,
with the keywords "iniital-key" or "static-key"
to indicate whether the configured trust anchor
should be used for initialization of RFC 5011 key
management, or as a permanent trust anchor.

The "static-key" keyword will generate a warning if
used for the root zone.

Configurations using "trusted-keys" or "managed-keys"
will continue to work with no changes, but will
generate warnings in the log. In a future release,
these options will be marked obsolete. [GL #6]

5247. [cleanup] The 'cleaning-interval' option has been removed.
[GL !1731]

5246. [func] Log TSIG if appropriate in 'sending notify to' message.

significant number of incoming packets were
rejected. (CVE-2019-6471) [GL #942]

5243. [bug] Fix a possible race between dispatcher and socket
code in a high-load cold-cache resolver scenario.
[GL #943]

5242. [bug] In relaxed qname minimization mode, fall back to
normal resolution when encountering a lame
delegation, and use _.domain/A queries rather
than domain/NS. [GL #1055]

5241. [bug] Fix Ed448 private and public key ASN.1 prefix blobs.
[GL #225]

5240. [bug] Remove key id calculation for RSAMD5. [GL #996]

and switch isc_hash_function() to use SipHash 2-4.
[GL #605]

5235. [cleanup] Refactor lib/isc/app.c to be thread-safe, unused
parts of the API has been removed and the
isc_appctx_t data type has been changed to be
fully opaque. [GL #1023]

5234. [port] arm: just use the compiler's default support for
yield. [GL #981]

--- 9.15.0 released ---

5233. [bug] Negative trust anchors did not work with "forward only;"
to validating resolvers. [GL #997]

5232. [placeholder]

5231. [protocol] Add support for displaying CLIENT-TAG and SERVER-TAG.
[GL #960]

5230. [protocol] The SHA-1 hash algorithm is no longer used when
generating DS and CDS records. [GL #1015]

5229. [protocol] Enforce known SSHFP fingerprint lengths. [GL #852]

5228. [func] If trusted-keys and managed-keys were configured
simultaneously for the same name, the key could
not be be rolled automatically. This is now
a fatal configuration error. [GL #868]

5227. [placeholder]

5226. [placeholder]

5225. [func] Allow dig to print out AAAA record fully expanded.
with +[no]expandaaaa. [GL #765]

5224. [bug] Only test provide-ixfr on TCP streams. [GL #991]

5223. [bug] Fixed a race in the filter-aaaa plugin accessing
the hash table. [GL #1005]

5216. [bug] Fetches-per-zone counter wasn't updated correctly
when doing qname minimization. [GL #992]

5215. [bug] Change #5124 was incomplete; named could still
return FORMERR instead of SERVFAIL in some cases.
[GL #990]

5214. [bug] win32: named now removes its lock file upon shutdown.
[GL #979]

5213. [bug] win32: Eliminated a race which allowed named.exe running
as a service to be killed prematurely during shutdown.
[GL #978]

5212. [placeholder]

5211. [bug] Allow out-of-zone additional data to be included
in authoritative responses if recursion is allowed
and "minimal-responses" is disabled. This behavior
was inadvertently removed in change #4605. [GL #817]

5210. [bug] When dnstap is enabled and recursion is not
available, incoming queries are now logged
as "auth". Previously, this depended on whether
recursion was requested by the client, not on
whether recursion was available. [GL #963]

5209. [bug] When update-check-ksk is true, add_sigs was not
considering offline keys, leaving record sets signed
with the incorrect type key. [GL #763]

5208. [test] Run valid rdata wire encodings through totext+fromtext
and tofmttext+fromtext methods to check these methods.
[GL #899]

5207. [test] Check delv and dig TTL values. [GL #965]

DNSKEY, CDNSKEY and RKEY. [GL #899]

5202. [bug] <dns/ecs.h> was missing ISC_LANG_ENDDECLS. [GL #976]

5201. [bug] Fix a possible deadlock in RPZ update code. [GL #973]

5200. [security] tcp-clients settings could be exceeded in some cases,
which could lead to exhaustion of file descriptors.
(CVE-2018-5743) [GL #615]

5199. [security] In certain configurations, named could crash
if nxdomain-redirect was in use and a redirected
query resulted in an NXDOMAIN from the cache.
(CVE-2019-6467) [GL #880]

5198. [bug] If a fetch context was being shut down and, at the same
time, we returned from qname minimization, an INSIST
could be hit. [GL #966]

5197. [bug] dig could die in best effort mode on multiple SIG(0)
records. Similarly on multiple OPT and multiple TSIG
records. [GL #920]

5196. [bug] make install failed with --with-dlopen=no. [GL #955]

5195. [bug] "allow-update" and "allow-update-forwarding" were
treated as configuration errors if used at the
options or view level. [GL #913]

5194. [bug] Enforce non empty ZOMEMD hash. [GL #899]

5193. [bug] EID and NIMLOC failed to do multi-line output
correctly. [GL #899]

[GL #806]

5189. [cleanup] Remove revoked root DNSKEY from bind.keys. [GL #945]

5188. [func] The "dnssec-enable" option is deprecated and no
longer has any effect; DNSSEC responses are
always enabled. [GL #866]

5187. [test] Set time zone before running any tests in dnstap_test.
[GL #940]

5186. [cleanup] More dnssec-keygen manual tidying. [GL !1678]

5185. [placeholder]

5184. [bug] Missing unlocks in sdlz.c. [GL #936]

5183. [bug] Reinitialize ECS data before reusing client
structures. [GL #881]

5182. [bug] Fix a high-load race/crash in handling of
isc_socket_close() in resolver. [GL #834]

5181. [func] Add a mechanism for a DLZ module to signal that
the view's allow-transfer ACL should be used to
determine whether transfers are allowed. [GL #803]

5180. [bug] delv now honors the operating system's preferred
ephemeral port range. [GL #925]

5179. [cleanup] Replace some vague type declarations with the more
specific dns_secalg_t and dns_dsdigest_t.
Thanks to Tony Finch. [GL !1498]

5178. [bug] Handle EDQUOT (disk quota) and ENOSPC (disk full)
errors when writing files. [GL #902]

5177. [func] Add the ability to specify in named.conf whether a
response-policy zone's SOA record should be added
to the additional section (add-soa yes/no). [GL #865]

test. [GL #926]

5175. [bug] Fixed a problem with file input in dnssec-keymgr,
dnssec-coverage and dnssec-checkds when using
python3. [GL #882]

5174. [doc] Tidy dnssec-keygen manual. [GL !1557]

5173. [bug] Fixed a race in socket code that could occur when
accept, send, or recv were called from an event
loop but the socket had been closed by another
thread. [RT #874]

5172. [bug] nsupdate now honors the operating system's preferred
ephemeral port range. [GL #905]

5171. [func] named plugins are now installed into a separate
directory. Supplying a filename (a string without path
separators) in a "plugin" configuration stanza now
causes named to look for that plugin in that directory.
[GL #878]

5170. [test] Added --with-dlz-filesystem to feature-test. [GL !1587]

5169. [bug] The presence of certain types in an otherwise
empty node could cause a crash while processing a
type ANY query. [GL #901]

5168. [bug] Do not crash on shutdown when RPZ fails to load. Also,
keep previous version of the database if RPZ fails to
load. [GL #813]

5167. [bug] nxdomain-redirect could sometimes lookup the wrong

trust anchors. [GL #873]

5160. [contrib] Added DNAME support to the DLZ LDAP schema. Also
fixed a compilation bug affecting several DLZ
modules. [GL #872]

5159. [bug] dnssec-coverage was incorrectly ignoring
names specified on the command line without
trailing dots. [GL !1478]

5158. [protocol] Add support for AMTRELAY and ZONEMD. [GL #867]

5157. [bug] Nslookup now errors out if there are extra command
line arguments. [GL #207]

5156. [doc] Extended and refined the section of the ARM describing
mirror zones. [GL #774]

5155. [func] "named -V" now outputs the default paths to
named.conf, rndc.conf, bind.keys, and other
files used or created by named and other tools, so
that the correct paths to these files can quickly be
determined regardless of the configure settings
used when BIND was built. [GL #859]

5154. [bug] dig: process_opt could be called twice on the same
message leading to a assertion failure. [GL #860]

number of messages) are now logged for outgoing
transfers as well as incoming ones. [GL #513]

5152. [func] Improved logging of DNSSEC key events:
- Zone signing and DNSKEY maintenance events are
now logged to the "dnssec" category
- Messages are now logged when DNSSEC keys are
published, activated, inactivated, deleted,
or revoked.
[GL #714]

5151. [func] Options that have been been marked as obsolete in
named.conf for a very long time are now fatal
configuration errors. [GL #358]

5150. [cleanup] Remove the ability to compile BIND with assertions
disabled. [GL #735]

5149. [func] "rndc dumpdb" now prints a line above a stale RRset
indicating how long the data will be retained in the
cache for emergency use. [GL #101]

5148. [bug] named did not sign the TKEY response. [GL #821]

5147. [bug] dnssec-keymgr: Add a five-minute margin to better
handle key events close to 'now'. [GL #848]

5146. [placeholder]

5145. [func] Use atomics instead of locked variables for isc_quota
and isc_counter. [GL !1389]

5144. [bug] dig now returns a non-zero exit code when a TCP
connection is prematurely closed by a peer more than
once for the same lookup. [GL #820]

5143. [bug] dnssec-keymgr and dnssec-coverage failed to find
key files for zone names ending in ".". [GL #560]

5142. [cleanup] Removed "configure --disable-rpz-nsip" and
"--disable-rpz-nsdname" options. "nsip-enable"
and "nsdname-enable" both now default to yes,
regardless of compile-time settings. [GL #824]

5141. [security] Zone transfer controls for writable DLZ zones were
not effective as the allowzonexfr method was not being
called for such zones. (CVE-2019-6465) [GL #790]

5140. [bug] Don't immediately mark existing keys as inactive and
deleted when running dnssec-keymgr for the first
time. [GL #117]

5139. [bug] If possible, don't use forwarders when priming.
This ensures we can get root server IP addresses
from priming query response glue, which may not
be present if the forwarding server is returning
minimal responses. [GL #752]

5138. [bug] Under some circumstances named could hit an assertion
failure when doing qname minimization when using
forwarders. [GL #797]

5137. [func] named now logs messages whenever a mirror zone becomes
usable or unusable for resolution purposes. [GL #818]

5136. [cleanup] Check in named-checkconf that allow-update and
allow-update-forwarding are not set at the
view/options level; fix documentation. [GL #512]

5135. [port] sparc: Use smt_pause() instead of pause. [GL #816]

5134. [bug] win32: WSAStartup was not called before getservbyname

a negative response. [GL #804]

5124. [bug] Named could incorrectly return FORMERR rather than
SERVFAIL. [GL #804]

5123. [bug] dig could hang indefinitely after encountering an error
before creating a TCP socket. [GL #692]

5122. [bug] In a "forward first;" configuration, a forwarder
timeout did not prevent that forwarder from being
queried again after falling back to full recursive
resolution. [GL #315]

5121. [contrib] dlz_stub_driver.c fails to return ISC_R_NOTFOUND on none
matching zone names. [GL !1299]

5120. [placeholder]

5119. [placeholder]
