Import bind-9.16.37 (previous was bind-9.16.33)

--- 9.16.37 released ---

6067. [security] Fix serve-stale crash when recursive clients soft quota
is reached. (CVE-2022-3924) [GL #3619]

6066. [security] Handle RRSIG lookups when serve-stale is active.
(CVE-2022-3736) [GL #3622]

6064. [security] An UPDATE message flood could cause named to exhaust all
available memory. This flaw was addressed by adding a
new "update-quota" statement that controls the number of
simultaneous UPDATE messages that can be processed or
forwarded. The default is 100. A stats counter has been
added to record events when the update quota is
exceeded, and the XML and JSON statistics version
numbers have been updated. (CVE-2022-3094) [GL #3523]

6062. [func] The DSCP implementation, which has only been
partly operational since 9.16.0, is now marked as
deprecated. Configuring DSCP values in named.conf
will cause a warning will be logged. [GL #3773]

6060. [bug] Fix a use-after-free bug in dns_zonemgr_releasezone()
by detaching from the zone manager outside of the write
lock. [GL #3768]

6059. [bug] In some serve stale scenarios, like when following an
expired CNAME record, named could return SERVFAIL if the
previous request wasn't successful. Consider non-stale
data when in serve-stale mode. [GL #3678]

6058. [bug] Prevent named from crashing when "rndc delzone"
attempts to delete a zone added by a catalog zone.
[GL #3745]

6050. [bug] Changes to the RPZ response-policy min-update-interval
and add-soa options now take effect as expected when
named is reconfigured. [GL #3740]

6048. [bug] Fix a log message error in dns_catz_update_from_db(),
where serials with values of 2^31 or larger were logged
incorrectly as negative numbers. [GL #3742]

6045. [cleanup] The list of supported DNSSEC algorithms changed log
level from "warning" to "notice" to match named's other
startup messages. [GL !7217]

6044. [bug] There was an "RSASHA236" typo in a log message.
[GL !7206]

--- 9.16.36 released ---

6043. [bug] The key file IO locks objects would never get
deleted from the hashtable due to off-by-one error.
[GL #3727]

6042. [bug] ANY responses could sometimes have the wrong TTL.
[GL #3613]

6040. [bug] Speed up the named shutdown time by explicitly
canceling all recursing ns_client objects for
each ns_clientmgr. [GL #3183]

6039. [bug] Removing a catalog zone from catalog-zones without
also removing the referenced zone could leave a
dangling pointer. [GL #3683]

6031. [bug] Move the "final reference detached" log message
from dns_zone unit to the DEBUG(1) log level.
[GL #3707]

6024. [func] Deprecate 'auto-dnssec'. [GL #3667]

6021. [bug] Use the current domain name when checking answers from
a dual-stack-server. [GL #3607]

6020. [bug] Ensure 'named-checkconf -z' respects the check-wildcard
option when loading a zone. [GL #1905]

6017. [bug] The view's zone table was not locked when it should
have been leading to race conditions when external
extensions that manipulate the zone table where in
use. [GL #3468]

--- 9.16.35 released ---

6013. [bug] Fix a crash that could happen when you change
a dnssec-policy zone with NSEC3 to start using
inline-signing. [GL #3591]

6009. [bug] Don't trust a placeholder KEYDATA from the managed-keys
zone by adding it into secroots. [GL #2895]

6008. [bug] Fixed a race condition that could cause a crash
in dns_zone_synckeyzone(). [GL #3617]

6002. [bug] Fix a resolver prefetch bug when the record's TTL value
is equal to the configured prefetch eligibility value,
but the record was erroneously not treated as eligible
for prefetching. [GL #3603]

6001. [bug] Always call dns_adb_endudpfetch() after calling
dns_adb_beginudpfetch() for UDP queries in resolver.c,
in order to adjust back the quota. [GL #3598]

6000. [bug] Fix a startup issue on Solaris systems with many
(reportedly > 510) CPUs. Thanks to Stacey Marshall from
Oracle for deep investigation of the problem. [GL #3563]

5999. [bug] rpz-ip rules could be ineffective in some scenarios
with CD=1 queries. [GL #3247]

5998. [bug] The RecursClients statistics counter could overflow
in certain resolution scenarios. [GL #3584]

5996. [bug] Fix a couple of bugs in cfg_print_duration(), which
could result in generating incomplete duration values
when printing the configuration using named-checkconf.
[GL !6880]

--- 9.16.34 released ---

5991. [protocol] Add support for parsing and validating "dohpath" to
SVCB. [GL #3544]

5988. [bug] Some out of memory conditions in opensslrsa_link.c
could lead to memory leaks. [GL #3551]

5984. [func] 'named -V' now reports the list of supported
DNSSEC/DS/HMAC algorithms and the supported TKEY modes.
[GL #3541]

5983. [bug] Changing just the TSIG key names for primaries in
catalog zones' member zones was not effective.
[GL #3557]

5973. [bug] Fixed a possible invalid detach in UPDATE
processing. [GL #3522]

5963. [bug] Ensure struct named_server is properly initialized.
[GL #6531]

5921. [test] Convert system tests to use a default DNSKEY algorithm
where the test is not DNSKEY algorithm specific.

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]

seconds, following RFC 8767 recommendations. [GL #2248]

5456. [func] Added "primaries" as a synonym for "masters" in
named.conf, and "primary-only" as a synonym for
"master-only" in the parameters to "notify", to bring
terminology up-to-date with RFC 8499. [GL #1948]

5362. [func] Limit the size of IXFR responses so that AXFR will
be used instead if it would be smaller. This is
controlled by the "max-ixfr-ratio" option, which
is a percentage representing the ratio of IXFR size
to the size of the entire zone. This value cannot
exceed 100%, which is the default. [GL #1515]

--- 9.16.11 released ---

5559. [bug] The --with-maxminddb=PATH form of the build-time option
enabling support for libmaxminddb was not working
correctly. This has been fixed. [GL #2366]

5557. [bug] Prevent RBTDB instances from being destroyed by multiple
threads at the same time. [GL #2317]

5556. [bug] Further tweak newline printing in dnssec-signzone and
dnssec-verify. [GL #2359]

5555. [bug] server->reload_status was not properly initialized.
[GL #2361]

5554. [bug] dnssec-signzone and dnssec-verify were missing newlines
between log messages. [GL #2359]

5553. [bug] When reconfiguring named, removing "auto-dnssec" did not
turn off DNSSEC maintenance. [GL #2341]

5552. [func] When switching to "dnssec-policy none;", named now
permits a safe transition to insecure mode and publishes
the CDS and CDNSKEY DELETE records, as described in RFC
8078. [GL #1750]

5551. [bug] named no longer attempts to assign threads to CPUs
outside the CPU affinity set. Thanks to Ole Bjørn
Hessen. [GL #2245]

5550. [func] dnssec-signzone and named now log a warning when falling
back to the "increment" SOA serial method. [GL #2058]

5545. [func] OS support for load-balanced sockets is no longer
required to receive incoming queries in multiple netmgr
threads. [GL #2137]

5543. [bug] Fix UDP performance issues caused by making netmgr
callbacks asynchronous-only. [GL #2320]

5542. [bug] Refactor netmgr. [GL #1920] [GL #2034] [GL #2061]
[GL #2194] [GL #2221] [GL #2266] [GL #2283] [GL #2318]
[GL #2321]

--- 9.16.10 released ---

5544. [func] Restore the default value of "nocookie-udp-size" to 4096
bytes. [GL #2250]

5541. [func] Adjust the "max-recursion-queries" default from 75 to
100. [GL #2305]

5540. [port] Fix building with native PKCS#11 support for AEP Keyper.
[GL #2315]

5539. [bug] Tighten handling of missing DNS COOKIE responses over
UDP by falling back to TCP. [GL #2275]

5538. [func] Add NSEC3 support to KASP. A new option for
"dnssec-policy", "nsec3param", can be used to set the
desired NSEC3 parameters. NSEC3 salt collisions are
automatically prevented during resalting. Salt
generation is now logged with zone context. [GL #1620]

5534. [bug] The CNAME synthesized from a DNAME was incorrectly
followed when the QTYPE was CNAME or ANY. [GL #2280]

--- 9.16.9 released ---

5533. [func] Add the "stale-refresh-time" option, a time window that
starts after a failed lookup, during which a stale RRset
is served directly from cache before a new attempt to
refresh it is made. [GL #2066]

5530. [bug] dnstap did not capture responses to forwarded UPDATE
requests. [GL #2252]

5527. [bug] A NULL pointer dereference occurred when creating an NTA
recheck query failed. [GL #2244]

5525. [bug] Change 5503 inadvertently broke cross-compilation by
replacing a call to AC_LINK_IFELSE() with a call to
AC_RUN_IFELSE() in configure.ac. This has been fixed,
making cross-compilation possible again. [GL #2237]

5523. [bug] The initial lookup in a zone transitioning to/from a
signed state could fail if the DNSKEY RRset was not
found. [GL #2236]

5522. [bug] Fixed a race/NULL dereference in TCPDNS send. [GL #2227]

5520. [bug] Fixed a number of shutdown races, reference counting
errors, and spurious log messages that could occur
in the network manager. [GL #2221]

5518. [bug] Stub zones now work correctly with primary servers using
"minimal-responses yes". [GL #1736]

5517. [bug] Do not treat UV_EOF as a TCP4RecvErr or a TCP6RecvErr.
[GL #2208]

--- 9.16.8 released ---

5516. [func] The default EDNS buffer size has been changed from 4096
to 1232 bytes. [GL #2183]

5515. [func] Add 'rndc dnssec -rollover' command to trigger a manual
rollover for a specific key. [GL #1749]

5514. [bug] Fix KASP expected key size for Ed25519 and Ed448.
[GL #2171]

5513. [doc] The ARM section describing the "rrset-order" statement
was rewritten to make it unambiguous and up-to-date with
the source code. [GL #2139]

5512. [bug] "rrset-order" rules using "order none" were causing
named to crash despite named-checkconf treating them as
valid. [GL #2139]

5511. [bug] 'dig -u +yaml' failed to display timestamps to the
microsecond. [GL #2190]

5510. [bug] Implement the attach/detach semantics for dns_message_t
to fix a data race in accessing an already-destroyed
fctx->rmessage. [GL #2124]

5509. [bug] filter-aaaa: named crashed upon shutdown if it was in
the process of recursing for A RRsets. [GL #1040]

5508. [func] Added new parameter "-expired" for "rndc dumpdb" that
also prints expired RRsets (awaiting cleanup) to the
dump file. [GL #1870]

5507. [bug] Named could compute incorrect SIG(0) responses.
[GL #2109]

5506. [bug] Properly handle failed sysconf() calls, so we don't
report invalid memory size. [GL #2166]

5505. [bug] Updating contents of a mixed-case RPZ could cause some
rules to be ignored. [GL #2169]

5503. [bug] Cleaned up reference counting of network manager
handles, now using isc_nmhandle_attach() and _detach()
instead of _ref() and _unref(). [GL #2122]

--- 9.16.7 released ---

5501. [func] Log CDS/CDNSKEY publication. [GL #1748]

5500. [bug] Fix (non-)publication of CDS and CDNSKEY records.
[GL #2103]

5499. [func] Add '-P ds' and '-D ds' arguments to dnssec-settime.
[GL #1748]

5497. [bug] 'dig +bufsize=0' failed to disable EDNS. [GL #2054]

5496. [bug] Address a TSAN report by ensuring each rate limiter
object holds a reference to its task. [GL #2081]

5495. [bug] With query minimization enabled, named failed to
resolve ip6.arpa. names that had extra labels to the
left of the IPv6 part. [GL #1847]

5494. [bug] Silence the EPROTO syslog message on older systems.
[GL #1928]

5493. [bug] Fix off-by-one error when calculating new hash table
size. [GL #2104]

5492. [bug] Tighten LOC parsing to reject a period (".") and/or "m"
as a value. Fix handling of negative altitudes which are
not whole meters. [GL #2074]

5491. [bug] rbtversion->glue_table_size could be read without the
appropriate lock being held. [GL #2080]

5489. [bug] Named erroneously accepted certain invalid resource
records that were incorrectly processed after
subsequently being written to disk and loaded back, as
the wire format differed. Such records include: CERT,
IPSECKEY, NSEC3, NSEC3PARAM, NXT, SIG, TLSA, WKS, and
X25. [GL !3953]

5488. [bug] NTA code needed to have a weak reference on its
associated view to prevent the latter from being deleted
while NTA tests were being performed. [GL #2067]

5486. [func] Add 'rndc dnssec -checkds' command, which signals to
named that the DS record for a given zone or key has
been updated in the parent zone. [GL #1613]

--- 9.16.6 released ---

5484. [func] Expire zero TTL records quickly rather than using them
for stale answers. [GL #1829]

5483. [func] A new configuration option "stale-cache-enable" has been
introduced to enable or disable keeping stale answers in
cache. [GL #1712]

5482. [bug] If the Duplicate Address Detection (DAD) mechanism had
not yet finished after adding a new IPv6 address to the
system, BIND 9 would fail to bind to IPv6 addresses in a
tentative state. [GL #2038]

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

5480. [security] When BIND 9 was compiled with native PKCS#11 support, it
was possible to trigger an assertion failure in code
determining the number of bits in the PKCS#11 RSA public
key with a specially crafted packet. (CVE-2020-8623)
[GL #2037]

5479. [security] named could crash in certain query resolution scenarios
where QNAME minimization and forwarding were both
enabled. (CVE-2020-8621) [GL #1997]

5478. [security] It was possible to trigger an assertion failure by
sending a specially crafted large TCP DNS message.
(CVE-2020-8620) [GL #1996]

5477. [bug] The idle timeout for connected TCP sockets, which was
previously set to a high fixed value, is now derived
from the client query processing timeout configured for
a resolver. [GL #2024]

5476. [security] It was possible to trigger an assertion failure when
verifying the response to a TSIG-signed request.
(CVE-2020-8622) [GL #2028]

5475. [bug] Wildcard RPZ passthru rules could incorrectly be
overridden by other rules that were loaded from RPZ
zones which appeared later in the "response-policy"
statement. This has been fixed. [GL #1619]

5474. [bug] dns_rdata_hip_next() failed to return ISC_R_NOMORE
when it should have. [GL !3880]

5473. [func] The RBT hash table implementation has been changed
to use a faster hash function (HalfSipHash2-4) and
Fibonacci hashing for better distribution. Setting
"max-cache-size" now preallocates a fixed-size hash
table so that rehashing does not cause resolution
brownouts while the hash table is grown. [GL #1775]

5471. [bug] The introduction of KASP support inadvertently caused
the second field of "sig-validity-interval" to always be
calculated in hours, even in cases when it should have
been calculated in days. This has been fixed. (Thanks to
Tony Finch.) [GL !3735]

5469. [port] On illumos, a constant called SEC is already defined in
<sys/time.h>, which conflicts with an identically named
constant in libbind9. This conflict has been resolved.
[GL #1993]

5468. [bug] Addressed potential double unlock in process_fd().
[GL #2005]

5466. [bug] Addressed an error in recursive clients stats reporting.
[GL #1719]

5465. [func] Added fallback to built-in trust-anchors, managed-keys,
or trusted-keys if the bindkeys-file (bind.keys) cannot
be parsed. [GL #1235]

5464. [bug] Requesting more than 128 files to be saved when rolling
dnstap log files caused a buffer overflow. This has been
fixed. [GL #1989]

5462. [bug] Move LMDB locking from LMDB itself to named. [GL #1976]

5461. [bug] The STALE rdataset header attribute was updated while
the write lock was not being held, leading to incorrect
statistics. The header attributes are now converted to
use atomic operations. [GL #1475]

[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]

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]

explicitly instead, because libuv doesn't support
pktinfo control messages. [GL #1558]

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]

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]

--- 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

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`.

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]

"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

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
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]

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]

5221. [test] Enable parallel execution of system tests on
Windows. [GL !4101]

5220. [cleanup] Refactor the isc_stat structure to take advantage
of stdatomic. [GL !1493]

5219. [bug] Fixed a race in the filter-aaaa plugin that could
trigger a crash when returning an instance object
to the memory pool. [GL #982]

5217. [bug] Restore key id calculation for RSAMD5. [GL #996]

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]

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]

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]

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]

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

mirror zones. [GL #774]

5155. [func] "named -V" now outputs the default paths to
named.conf, rndc.conf, bind.keys, and other

that the correct paths to these files can quickly be
determined regardless of the configure settings
used when BIND was built. [GL #859]

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]

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]

timeout did not prevent that forwarder from being
queried again after falling back to full recursive
resolution. [GL #315]

--- 9.14.5 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]

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]

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

5268. [bug] named could crash during configuration if
configured to use "geoip continent" ACLs with
legacy GeoIP. [GL #1163]

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. [GL #605]

5236. [func] Add SipHash 2-4 implementation in lib/isc/siphash.c
and switch isc_hash_function() to use SipHash 2-4.
[GL #605]

--- 9.14.4 released ---

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

5258. [func] Added support for the GeoIP2 API from MaxMind,
when BIND is compiled using "configure --with-geoip2".
The legacy GeoIP API can be enabled by using
"configure --with-geoip" instead. These options
cannot be used together.

Certain geoip ACL settings that were available with
legacy GeoIP are not available when using GeoIP2.
See the ARM for details. [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]

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

--- 9.14.3 released ---

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 minimizatiom 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]

5238. [bug] Fix a possible deadlock in TCP code. [GL #1046]

5237. [bug] Recurse to find the root server list with 'dig +trace'.
[GL #1028]

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

--- 9.14.2 released ---

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

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

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

5228. [cleanup] If trusted-keys and managed-keys are configured
simultaneously for the same name, the key cannot
be rolled automatically. This configuration now
logs a warning. [GL #868]

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]

5222. [bug] 'delv -t ANY' could leak memory. [GL #983]

5221. [test] Enable parallel execution of system tests on
Windows. [GL !4101]

5220. [cleanup] Refactor the isc_stat structure to take advantage
of stdatomic. [GL !1493]

5219. [bug] Fixed a race in the filter-aaaa plugin that could
trigger a crash when returning an instance object
to the memory pool. [GL #982]

5218. [bug] Conditionally include <dlfcn.h>. [GL #995]

5217. [bug] Restore key id calculation for RSAMD5. [GL #996]

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]

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]

5206. [bug] Delv could print out bad TTLs. [GL #965]

will be accepted by dns_rdata_fromwire(). [GL #852]

5203. [bug] Enforce whether key rdata exists or not in KEY,
DNSKEY, CDNSKEY and RKEY. [GL #899]

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

5108. [bug] Named could fail to determine bottom of zone when
removing out of date keys leading to invalid NSEC
and NSEC3 records being added to the zone. [GL #771]

5107. [bug] 'host -U' did not work. [GL #769]

5106. [experimental] A new "plugin" mechanism has been added to allow
extension of query processing functionality through
the use of dynamically loadable libraries. A
"filter-aaaa.so" plugin has been implemented,
replacing the filter-aaaa feature that was formerly
implemented as a native part of BIND.

The "filter-aaaa", "filter-aaaa-on-v4" and
"filter-aaaa-on-v6" options can no longer be
configured using native named.conf syntax. However,
loading the filter-aaaa.so plugin and setting its
parameters provides identical functionality.

Note that the plugin API is a work in progress and
is likely to evolve as further plugins are
implemented. [GL #15]

5105. [bug] Fix a race between process_fd and socketclose in
unix socket code. [GL #744]

Thanks to Tony Finch. [GL !1157]

5103. [bug] Add missing design by contract tests to dns_catz*.
[GL #748]

5102. [bug] dnssec-coverage failed to use the default TTL when
checking KSK deletion times leading to a exception.
[GL #585]

5101. [bug] Fix default installation path for Python modules and
remove the dnspython dependency accidentally introduced
by change 4970. [GL #730]

5100. [func] Pin resolver tasks to specific task queues. [GL !1117]

5099. [func] Failed mutex and conditional creations are always
fatal. [GL #674]

--- 9.13.4 released ---

5098. [func] Failed memory allocations are now fatal. [GL #674]

5097. [cleanup] Remove embedded ATF unit testing framework
from BIND source distribution. [GL !875]

5096. [func] Use multiple event loops in socket code, and
make network threads CPU-affinitive. This
significantly improves performance on large
systems. [GL #666]

5095. [test] Converted all unit tests from ATF to CMocka;
removed the source code for the ATF libraries.
Build with "configure --with-cmocka" to enable
unit testing. [GL #620]

5094. [func] Add 'dig -r' to disable reading of .digrc. [GL !970]

5093. [bug] Log lame qname-minimization servers only if they're
really lame. [GL #671]

5092. [bug] Address memory leak on SIGTERM in nsupdate when using
GSS-TSIG. [GL #558]

5091. [func] Two new global and per-view options min-cache-ttl
and min-ncache-ttl [GL #613]

5090. [bug] dig and mdig failed to properly preparse dash value
pairs when value was a seperate argument and started
with a dash. [GL #584]

5089. [bug] Restore localhost fallback in dig and host which is
used when no nameserver addresses present in
/etc/resolv.conf are usable due to the requested
address family restrictions. [GL #433]

5088. [bug] dig/host/nslookup could crash when interrupted close to
a query timeout. [GL #599]

5087. [test] Check that result tables are complete. [GL #676]

5086. [func] Log of RPZ now includes the QTYPE and QCLASS. [GL #623]

5085. [bug] win32: Restore looking up nameservers, search list,
etc. [GL #186]

5084. [placeholder]

5083. [func] Add autoconf macro AX_POSIX_SHELL, so we
can use POSIX-compatible shell features
in the scripts.

5082. [bug] Fixed a race that could cause a crash in
dig/host/nslookup. [GL #650]

5081. [func] Use per-worker queues in task manager, make task
runners CPU-affine. [GL #659]

5080. [func] Improvements to "rndc nta" user interface:
- catch and report invalid command line options
- when removing an NTA from all views, do not
abort with an error if the NTA was not found
in one of the views
- include the view name in "rndc nta -dump"
output, for consistency with the add and remove
actions
Thanks to Tony Finch. [GL !816]

5079. [func] Disable IDN processing in dig and nslookup
when not on a tty. [GL #653]

5078. [cleanup] Require python components to be explicitly disabled if

"rate-limit" was configured. [GL #617]

5075. [bug] Refresh nameservers from cache when sending final
query in qname minimization. [GL #16]

5074. [cleanup] Remove vector socket functions - isc_socket_recvv(),
isc_socket_sendtov(), isc_socket_sendtov2(),
isc_socket_sendv() - in order to simplify socket code.
[GL #645]

5073. [bug] Destroy a task first when destroying rpzs and catzs.
[GL #84]

5072. [bug] Add unit tests for isc_buffer_copyregion() and fix its
behavior for auto-reallocated buffers. [GL #644]

5071. [bug] Comparision of NXT records was broken. [GL #631]

5070. [bug] Record types which support a empty rdata field were
not handling the empty rdata field case. [GL #638]

zone update. [GL !907]

5068. [bug] Fix a race in RPZ with min-update-interval set to 0.
[GL #643]

5067. [bug] Don't minimize qname when sending the query

in response-policy statements. [GL #641]

5065. [bug] Only set IPV6_USE_MIN_MTU on IPv6. [GL #553]

5064. [test] Initalize TZ environment variable before calling
dns_test_begin in dnstap_test. [GL #624]

5063. [test] In statschannel test try a few times before failing
when checking if the compressed output is the same as
uncompressed. [GL !909]

[GL #427]

5058. [func] Replace old message digest and hmac APIs with more
generic isc_md and isc_hmac APIs, and convert their
respective tests to cmocka. [GL #305]

5057. [protocol] Add support for ATMA. [GL #619]

5056. [placeholder]

5055. [func] A default list of primary servers for the root zone is
now built into named, allowing the "masters" statement
to be omitted when configuring an IANA root zone
mirror. [GL #564]

5054. [func] Attempts to use mirror zones with recursion disabled
are now considered a configuration error. [GL #564]

5053. [func] The only valid zone-level NOTIFY settings for mirror
zones are now "notify no;" and "notify explicit;".
[GL #564]

5052. [func] Mirror zones are now configured using "type mirror;"
rather than "mirror yes;". [GL #564]

5051. [doc] Documentation incorrectly stated that the
"server-addresses" static-stub zone option accepts
custom port numbers. [GL #582]

5050. [bug] The libirs version of getaddrinfo() was unable to parse
scoped IPv6 addresses present in /etc/resolv.conf.
[GL #187]

5049. [cleanup] QNAME minimization has been deeply refactored. [GL #16]

5048. [func] Add configure option to enable and enforce FIPS mode
in BIND 9. [GL #506]

5047. [bug] Messages logged for certain query processing failures
now include a more specific error description if it is
available. [GL #572]

5046. [bug] named could crash during shutdown if an RPZ
reload was in progress. [RT #46210]

5045. [func] Remove support for DNSSEC algorithms 3 (DSA)
and 6 (DSA-NSEC3-SHA1). [GL #22]

5044. [cleanup] If "dnssec-enable" is no, then "dnssec-validation"
now also defaults to no. [GL #388]

5043. [bug] Fix creating and validating EdDSA signatures. [GL #579]

5042. [test] Make the chained delegations in reclimit behave
like they would in a regular name server. [GL #578]

5041. [test] The chain test contains a incomplete delegation.
[GL #568]

5040. [func] Extended dnstap so that it can log UPDATE requests
and responses as separate message types. Thanks
to Greg Rabil. [GL #570]

5039. [bug] Named could fail to preserve owner name case of new
RRset. [GL #420]

5038. [bug] Chaosnet addresses were compared incorrectly.
[GL #562]

5037. [func] "allow-recursion-on" and "allow-query-cache-on"
each now default to the other if only one of them
is set, in order to be more consistent with the way
"allow-recursion" and "allow-query-cache" work.
Also we now ensure that both query-cache ACLs are
checked when determining cache access. [GL #319]

5036. [cleanup] Fixed a spacing/formatting error in some RPZ-related
error messages in the log. [GL !805]

5035. [test] Fixed errors that prevented the DNSRPS subtests
from running in the rpz and rpzrecurse system
tests. [GL #503]

5034. [bug] A race between threads could prevent zone maintenance
scheduled immediately after zone load from being
performed. [GL #542]

5033. [bug] When adding NTAs to multiple views using "rndc nta",
the text returned via rndc was incorrectly terminated
after the first line, making it look as if only one
NTA had been added. Also, it was not possible to
differentiate between views with the same name but
different classes; this has been corrected with the
addition of a "-class" option. [GL #105]

5032. [func] Add krb5-selfsub and ms-selfsub update policy rules.
[GL #511]

5031. [cleanup] Various defines in platform.h has been either dropped
if always or never triggered on supported platforms
or replaced with config.h equivalents if the defines
didn't have any impact on public headers. Workarounds
for LinuxThreads have been removed because NPTL is
available since Linux kernel 2.6.0. [GL #525]

5030. [bug] Align CMSG buffers to a 64-bit boundary, fixes crash
on architectures with strict alignment. [GL #521]

--- 9.13.3 released ---

5029. [func] Workarounds for servers that misbehave when queried
with EDNS have been removed, because these broken
servers and the workarounds for their noncompliance
cause unnecessary delays, increase code complexity,
and prevent deployment of new DNS features. See
https://dnsflagday.net for further details. [GL #150]

5028. [bug] Spread the initial RRSIG expiration times over the
entire working sig-validity-interval when signing a
zone in named to even out re-signing and transfer
loads. [GL #418]

5027. [func] Set SO_SNDBUF size on sockets. [GL #74]

5026. [bug] rndc reconfig should not touch already loaded zones.
[GL #276]

5025. [cleanup] Remove isc_keyboard family of functions. [GL #178]

5024. [func] Replace custom assembly for atomic operations with
atomic support from the compiler. The code will now use
C11 stdatomic, or __atomic, or __sync builtins with GCC
or Clang compilers, and Interlocked functions with MSVC.
[GL #10]

5023. [cleanup] Remove wrappers that try to fix broken or incomplete
implementations of IPv6, pthreads and other core
functionality required and used by BIND. [GL #192]

5022. [doc] Update ms-self, ms-subdomain, krb5-self, and
krb5-subdomain documentation. [GL !708]

5021. [bug] dig returned a non-zero exit code when it received a
reply over TCP after a retry. [GL #487]

5020. [func] RNG uses thread-local storage instead of locks, if
supported by platform. [GL #496]

5019. [cleanup] A message is now logged when ixfr-from-differences is
set at zone level for an inline-signed zone. [GL #470]

5018. [bug] Fix incorrect sizeof arguments in lib/isc/pk11.c.
[GL !588]

5017. [bug] lib/isc/pk11.c failed to unlink the session before
releasing the lock which is unsafe. [GL !589]

5016. [bug] Named could assert with overlapping filter-aaaa and
dns64 acls. [GL #445]

5015. [bug] Reloading all zones caused zone maintenance to cease
for inline-signed zones. [GL #435]

5014. [bug] Signatures loaded from the journal for the signed
version of an inline-signed zone were not scheduled for
refresh. [GL #482]

5013. [bug] A referral response with a non-empty ANSWER section was
inadvertently being treated as an error. [GL #390]

5012. [bug] Fix lock order reversal in pk11_initialize. [GL !590]

5011. [func] Remove support for unthreaded named. [GL #478]

5010. [func] New "validate-except" option specifies a list of
domains beneath which DNSSEC validation should not
be performed. [GL #237]

5009. [bug] Upon an OpenSSL failure, the first error in the OpenSSL
error queue was not logged. [GL #476]

5008. [bug] "rndc signing -nsec3param ..." requests were silently
ignored for zones which were not yet loaded or
transferred. [GL #468]

5007. [cleanup] Replace custom ISC boolean and integer data types
with C99 stdint.h and stdbool.h types. [GL #9]

5006. [cleanup] Code preparing a delegation response was extracted from
query_delegation() and query_zone_delegation() into a
separate function in order to decrease code
duplication. [GL #431]

5005. [bug] dnssec-verify, and dnssec-signzone at the verification
step, failed on some validly signed zones. [GL #442]

5004. [bug] 'rndc reconfig' could cause inline zones to stop
re-signing. [GL #439]

5003. [bug] dns_acl_isinsecure did not handle geoip elements.
[GL #406]

5002. [bug] mdig: Handle malformed +ednsopt option, support 100
+ednsopt options per query rather than 100 total and
address memory leaks if +ednsopt was specified.
[GL #410]

5001. [bug] Fix refcount errors on error paths. [GL !563]

5000. [bug] named_server_servestale() could leave the server in
exclusive mode if an error occured. [GL #441]

4999. [cleanup] Remove custom printf implementation in lib/isc/print.c.
[GL #261]

4998. [test] Make resolver and cacheclean tests more civilized.

4997. [security] named could crash during recursive processing
of DNAME records when "deny-answer-aliases" was
in use. (CVE-2018-5740) [GL #387]

4996. [bug] dig: Handle malformed +ednsopt option. [GL #403]

4995. [test] Add tests for "tcp-self" update policy. [GL !282]

4994. [bug] Trust anchor telemetry queries were not being sent
upstream for locally served zones. [GL #392]

4993. [cleanup] Remove support for silently ignoring 'no-change' deltas
from BIND 8 when processing an IXFR stream. 'no-change'
deltas will now trigger a fallback to AXFR as the
recovery mechanism. [GL #369]

4992. [bug] The wrong address was being logged for trust anchor
telemetry queries. [GL #379]

4991. [bug] "rndc reconfig" was incorrectly handling zones whose
"mirror" setting was changed. [GL #381]

4990. [bug] Prevent a possible NULL reference in pkcs11-keygen.
[GL #401]

4989. [cleanup] IDN support in dig has been reworked. IDNA2003
fallbacks were removed in the process. [GL #384]

4988. [bug] Don't synthesize NXDOMAIN from NSEC for records under
a DNAME.

--- 9.13.2 released ---

4987. [cleanup] dns_rdataslab_tordataset() and its related
dns_rdatasetmethods_t callbacks were removed as they
were not being used by anything in BIND. [GL #371]

4986. [func] When built on Linux, BIND now requires the libcap
library to set process privileges, unless capability
support is explicitly overridden with "configure
--disable-linux-caps". [GL #321]

4985. [func] Add a new slave zone option, "mirror", to enable
serving a non-authoritative copy of a zone that
is subject to DNSSEC validation before being
used. For now, this option is only meant to
facilitate deployment of an RFC 7706-style local
copy of the root zone. [GL #33]

4984. [bug] Improve handling of very large incremental
zone transfers to prevent journal corruption. [GL #339]

4983. [func] Add the ability to not return a DNS COOKIE option
when one is present in the request (answer-cookie no;).
[GL #173]

4982. [cleanup] Return FORMERR if the question section is empty
and no COOKIE option is present; this restores
older behavior except in the newly specified
COOKIE case. [GL #260]

4981. [bug] Fix race in cmsg buffer usage in socket code.
[GL #180]

4980. [bug] Named-checkconf failed to detect bad in-view targets.
[GL #288]

4979. [placeholder]

4978. [test] Fix error handling and resolver configuration in the
"rpz" system test. [GL #312]

4977. [func] When starting up, log the same details that
would be reported by 'named -V'. [GL #247]

4976. [bug] Log the label with invalid prefix length correctly
when loading RPZ zones. [GL #254]

4975. [bug] The server cookie computation for sha1 and sha256 did
not match the method described in RFC 7873. [GL #356]

4974. [bug] Restore default rrset-order to random. [GL #336]

4973. [func] verifyzone() and the functions it uses were moved to
libdns and refactored to prevent exit() from being
called upon failure. A side effect of that is that
dnssec-signzone and dnssec-verify now check for memory
leaks upon shutdown. [GL #266]

4972. [func] Declare the 'rdata' argument for dns_rdata_tostruct()
to be const. [GL #341]

4971. [bug] dnssec-signzone and dnssec-verify did not treat records
below a DNAME as out-of-zone data. [GL #298]

4970. [func] Add QNAME minimization option to resolver. [GL #16]

4969. [cleanup] Refactor zone logging functions. [GL #269]

--- 9.13.1 released ---

4968. [bug] If glue records are signed, attempt to validate them.
[GL #209]

4967. [cleanup] Add "answer-cookie" to the parser, marked obsolete.

4966. [placeholder]

4965. [func] Add support for marking options as deprecated.
[GL #322]

4964. [bug] Reduce the probabilty of double signature when deleting
a DNSKEY by checking if the node is otherwise signed
by the algorithm of the key to be deleted. [GL #240]

4963. [test] ifconfig.sh now uses "ip" instead of "ifconfig",
if available, to configure the test interfaces on
linux. [GL #302]

4962. [cleanup] Move 'named -T' processing to its own function.
[GL #316]

4961. [protocol] Remove support for ECC-GOST (GOST R 34.11-94).
[GL #295]

4960. [security] When recursion is enabled, but the "allow-recursion"
and "allow-query-cache" ACLs are not specified,
they should be limited to local networks,
but were inadvertently set to match the default
"allow-query", thus allowing remote queries.
(CVE-2018-5738) [GL #309]

4959. [func] NSID logging (enabled by the "request-nsid" option)
now has its own "nsid" category, instead of using the
"resolver" category. [GL !332]

4958. [bug] Remove redundant space from NSEC3 record. [GL #281]

4957. [func] The default setting for "dnssec-validation" is now
"auto", which activates DNSSEC validation using the
IANA root key. (The default can be changed back to
"yes", which activates DNSSEC validation only when keys
are explicitly configured in named.conf, by building
BIND with "configure --disable-auto-validation".)
[GL #30]

4956. [func] Change isc_random() to be just PRNG using xoshiro128**,
and add isc_nonce_buf() that uses CSPRNG. [GL #289]

4955. [cleanup] Silence cppcheck warnings in lib/dns/master.c.
[GL #286]

4954. [func] Messages about serving of stale answers are now
directed to the "serve-stale" logging category.
Also clarified serve-stale documentation. [GL !323]

4953. [bug] Removed the option to build the red black tree
database without a hash table; the non-hashing
version was buggy and is not needed. [GL #184]

4952. [func] Authoritative server support in named for the
EDNS CLIENT-SUBNET option (which was experimental
and not practical to deploy) has been removed.

The ECS option is still supported in dig and mdig
via the +subnet option, and can be parsed and logged
when received by named, but it is no longer used
for ACL processing. The "geoip-use-ecs" option
is now obsolete; a warning will be logged if it is
used in named.conf. "ecs" tags in an ACL definition
are also obsolete and will cause the configuration
to fail to load. [GL #32]

4951. [protocol] Add "HOME.ARPA" to list of built in empty zones as
per RFC 8375. [GL #273]

--- 9.13.0 released ---

4950. [bug] ISC_SOCKEVENTATTR_TRUNC was not be set. [GL #238]

4949. [placeholder]

4948. [bug] When request-nsid is turned on, EDNS NSID options
should be logged at level info. Since change 3741
they have been logged at debug(3) by mistake.
[GL !290]

4947. [func] Replace all random functions with isc_random(),
isc_random_buf() and isc_random_uniform() API.
[GL #221]

4946. [bug] Additional glue was not being returned by resolver
for unsigned zones since change 4596. [GL #209]

4945. [func] BIND can no longer be built without DNSSEC support.
A cryptography provder (i.e., OpenSSL or a hardware
service module with PKCS#11 support) must be
available. [GL #244]

4944. [cleanup] Silence cppcheck portability warnings in
lib/isc/tests/buffer_test.c. [GL #239]

4943. [bug] Change 4687 consumed too much memory when running
system tests with --with-tuning=large. Reduced the
hash table size to 512 entries for 'named -m record'
restoring the previous memory footprint. [GL #248]

4942. [cleanup] Consolidate multiple instances of splitting of
batchline in dig into a single function. [GL #196]

4941. [cleanup] Silence clang static analyzer warnings. [GL #196]

4940. [cleanup] Extract the loop in dns__zone_updatesigs() into
separate functions to improve code readability.
[GL #135]

4939. [test] Add basic unit tests for update_sigs(). [GL #135]

4938. [placeholder]

4937. [func] Remove support for OpenSSL < 1.0.0 [GL #191]

4936. [func] Always use OpenSSL or PKCS#11 random data providers,
and remove the --{enable,disable}-crypto-rand configure
options. [GL #165]

4935. [func] Add support for LibreSSL >= 2.7.0 (some OpenSSL 1.1.0
call were added). [GL #191]

4934. [security] The serve-stale feature could cause an assertion failure
in rbtdb.c even when stale-answer-enable was false.
Simultaneous use of stale cache records and NSEC
aggressive negative caching could trigger a recursion
loop. (CVE-2018-5737) [GL #185]

4933. [bug] Not creating signing keys for an inline signed zone
prevented changes applied to the raw zone from being
reflected in the secure zone until signing keys were
made available. [GL #159]

4932. [bug] Bumped signed serial of an inline signed zone was
logged even when an error occurred while updating
signatures. [GL #159]

4931. [func] Removed the "rbtdb64" database implementation.
[GL #217]

4930. [bug] Remove a bogus check in nslookup command line
argument processing. [GL #206]

4929. [func] Add the ability to set RA and TC in queries made by
dig (+[no]raflag, +[no]tcflag). [GL #213]

4928. [func] The "dnskey-sig-validity" option allows
"sig-validity-interval" to be overriden for signatures
covering DNSKEY RRsets. [GL #145]

4927. [placeholder]

4926. [func] Add root key sentinel support. To disable, add
'root-key-sentinel no;' to named.conf. [GL #37]

4925. [func] Several configuration options that define intervals
can now take TTL value suffixes (for example, 2h or 1d)
in addition to integer parameters. These include
max-cache-ttl, max-ncache-ttl, max-policy-ttl,
fstrm-set-reopen-interval, interface-interval, and
min-update-interval. [GL #203]

4924. [cleanup] Clean up the isc_string_* namespace and leave
only strlcpy and strlcat. [GL #178]

4923. [cleanup] Refactor socket and socket event options into
enum types. [GL !135]

4922. [bug] dnstap: Log the destination address of client
packets rather than the interface address.
[GL #197]

4921. [cleanup] Add dns_fixedname_initname() and refactor the caller
code to make usage of the new function, as a part of
refactoring dns_fixedname_*() macros were turned into
functions. [GL #183]

4920. [cleanup] Clean up libdns removing most of the backwards
compatibility wrappers.

4919. [cleanup] Clean up the isc_hash_* namespace and leave only
the FNV-1a hash implementation. [GL #178]

4918. [bug] Fix double free after keygen error in dnssec-keygen
when OpenSSL >= 1.1.0 is used and RSA_generate_key_ex
fails. [GL #109]

4917. [func] Support 64 RPZ policy zones by default. [GL #123]

4916. [func] Remove IDNA2003 support and the bundled idnkit-1.0
library.

4915. [func] Implement IDNA2008 support in dig by adding support
for libidn2. New dig option +idnin has been added,
which allows to process invalid domain names much
like dig without IDN support. libidn2 version 2.0
or higher is needed for +idnout enabled by default.

4914. [security] A bug in zone database reference counting could lead to
a crash when multiple versions of a slave zone were
transferred from a master in close succession.
(CVE-2018-5736) [GL #134]

4913. [test] Re-implemented older unit tests in bin/tests as ATF,
removed the lib/tests unit testing library. [GL #115]

4912. [test] Improved the reliability of the 'cds' system test.
[GL #136]

4911. [test] Improved the reliability of the 'mkeys' system test.
[GL #128]

4910. [func] Update util/check-changes to work on release branches.
[GL #113]

4909. [bug] named-checkconf did not detect in-view zone collisions.
[GL #125]

4908. [test] Eliminated unnecessary waiting in the allow_query
system test. Also changed its name to allow-query.
[GL #81]

4907. [test] Improved the reliability of the 'notify' system
test. [GL #59]

4906. [func] Replace getquad() with inet_pton(), completing
change #4900. [GL #56]

4905. [bug] irs_resconf_load() ignored resolv.conf syntax errors
when "domain" or "search" options were present in that
file. [GL #110]

4904. [bug] Temporarily revert change #4859. [GL #124]

4903. [bug] "check-mx fail;" did not prevent MX records containing
IP addresses from being added to a zone by a dynamic
update. [GL #112]

4902. [test] Improved the reliability of the 'ixfr' system
test. [GL #66]

4901. [func] "dig +nssearch" now lists the name servers
for a domain that time out, as well as the servers
that respond. [GL #64]

4900. [func] Remove all uses of inet_aton(). As a result of this
change, IPv4 addresses are now only accepted in
dotted-quad format. [GL #13]

4899. [test] Convert most of the remaining system tests to be able
to run in parallel, continuing the work from change
#4895. To take advantage of this, use "make -jN check",
where N is the number of processors to use. [GL #91]

4898. [func] Remove libseccomp based system-call filtering. [GL #93]

4897. [test] Update to rpz system test so that it doesn't recurse.
[GL #68]

4896. [test] cacheclean system test was not robust. [GL #82]

4895. [test] Allow some system tests to run in parallel.
[RT #46602]

4894. [bug] named could crash while rolling a dnstap output file.
[RT #46942]

4893. [bug] Address various issues reported by cppcheck. [GL #51]

4892. [bug] named could leak memory when "rndc reload" was invoked
before all zone loading actions triggered by a previous
"rndc reload" command were completed. [RT #47076]

4891. [placeholder]

4890. [func] Remove unused ondestroy callback from libisc.
[isc-projects/bind9!3]

4889. [func] Warn about the use of old root keys without the new
root key being present. Warn about dlv.isc.org's
key being present. Warn about both managed and
trusted root keys being present. [RT #43670]

4888. [test] Initialize sockets correctly in sample-update so
that the nsupdate system test will run on Windows.
[RT #47097]

4887. [test] Enable the rpzrecurse test to run on Windows.
[RT #47093]

4886. [doc] Document dig -u in manpage. [RT #47150]

4885. [security] update-policy rules that otherwise ignore the name
field now require that it be set to "." to ensure
that any type list present is properly interpreted.
[RT #47126]

4884. [bug] named could crash on shutdown due to a race between
shutdown_server() and ns__client_request(). [RT #47120]

4883. [cleanup] Improved debugging output from dnssec-cds. [RT #47026]

4882. [bug] Address potential memory leak in
dns_update_signaturesinc. [RT #47084]

4881. [bug] Only include dst_openssl.h when OpenSSL is required.
[RT #47068]

4880. [bug] Named wasn't returning the target of a cross-zone
CNAME between two served zones when recursion was
desired and available (RD=1, RA=1). (When this is
not the case, the CNAME target is deliberately
withheld to prevent accidental cache poisoning.)
[RT #47078]

4879. [bug] dns_rdata_caa:value_len field was too small.
[RT #47086]

4878. [bug] List 'ply' as a requirement for the 'isc' python
package. [RT #47065]

4877. [bug] Address integer overflow when exponentially
backing off retry intervals. [RT #47041]

4876. [bug] Address deadlock with accessing a keytable. [RT #47000]

4875. [bug] Address compile failures on older systems. [RT #47015]

4874. [bug] Wrong time display when reporting new keywarntime.
[RT #47042]

4873. [doc] Grammars for named.conf included in the ARM are now
automatically generated by the configuration parser
itself. As a side effect of the work needed to
separate zone type grammars from each other, this
also makes checking of zone statements in
named-checkconf more correct and consistent.
[RT #36957]

4872. [bug] Don't permit loading meta RR types such as TKEY
from master files. [RT #47009]

4871. [bug] Fix configure glitch in detecting stdatomic.h
support on systems with multiple compilers.
[RT #46959]

4870. [test] Update included ATF library to atf-0.21 preserving
the ATF tool. [RT #46967]

4869. [bug] Address some cases where NULL with zero length could
be passed to memmove which is undefined behavior and
can lead to bad optimization. [RT #46888]

4868. [func] dnssec-keygen can no longer generate HMAC keys.
Use tsig-keygen instead. [RT #46404]

4867. [cleanup] Normalize rndc on/off commands (validation,
querylog, serve-stale) so they all accept the
same synonyms for on/off (yes/no, true/false,
enable/disable). Thanks to Tony Finch. [RT #47022]

4866. [port] DST library initialization verifies MD5 (when MD5
was not disabled) and SHA-1 hash and HMAC support.
[RT #46764]

4865. [cleanup] Simplify handling isc_socket_sendto2() return values.
[RT #46986]

4864. [bug] named acting as a slave for a catalog zone crashed if
the latter contained a master definition without an IP
address. [RT #45999]

4863. [bug] Fix various other bugs reported by Valgrind's
memcheck tool. [RT #46978]

4862. [bug] The rdata flags for RRSIG were not being properly set
when constructing a rdataslab. [RT #46978]

4861. [bug] The isc_crc64 unit test was not endian independent.
[RT #46973]

4860. [bug] isc_int8_t should be signed char. [RT #46973]

4859. [bug] A loop was possible when attempting to validate
unsigned CNAME responses from secure zones;
this caused a delay in returning SERVFAIL and
also increased the chances of encountering
CVE-2017-3145. [RT #46839]

4858. [security] Addresses could be referenced after being freed
in resolver.c, causing an assertion failure.
(CVE-2017-3145) [RT #46839]

4857. [bug] Maintain attach/detach semantics for event->db,
event->node, event->rdataset and event->sigrdataset
in query.c. [RT #46891]

4856. [bug] 'rndc zonestatus' reported the wrong underlying type
for a inline slave zone. [RT #46875]

4855. [bug] isc_time_formatshorttimestamp produced incorrect
output. [RT #46938]

4854. [bug] query_synthcnamewildcard should stop generating the
response if query_synthwildcard fails. [RT #46939]

4853. [bug] Add REQUIRE's and INSIST's to isc_time_formatISO8601L
and isc_time_formatISO8601Lms. [RT #46916]

4852. [bug] Handle strftime() failing in isc_time_formatISO8601ms.
Add REQUIRE's and INSIST's to isc_time_formattimestamp,
isc_time_formathttptimestamp, isc_time_formatISO8601,
isc_time_formatISO8601ms. [RT #46892]

4851. [port] Support using kyua as well as atf-run to run the unit
tests. [RT #46853]

4850. [bug] Named failed to restart with multiple added zones in
lmdb database. [RT #46889]

4849. [bug] Duplicate zones could appear in the .nzf file if
addzone failed. [RT #46435]

4848. [func] Zone types "primary" and "secondary" can now be used
as synonyms for "master" and "slave" in named.conf.
[RT #46713]

4847. [bug] dnssec-dnskey-kskonly was not being honored for
CDS and CDNSKEY. [RT #46755]
