merge conflicts, adjust build.
--- 9.16.12 released ---
5578. [protocol] Make "check-names" accept A records below "_spf",
"_spf_rate", and "_spf_verify" labels in order to cater
for the "exists" SPF mechanism specified in RFC 7208
section 5.7 and appendix D.1. [GL #2377]
5577. [bug] Fix the "three is a crowd" key rollover bug in KASP by
correctly implementing Equation (2) of the "Flexible and
Robust Key Rollover" paper. [GL #2375]
5575. [bug] When migrating to KASP, BIND 9 considered keys with the
"Inactive" and/or "Delete" timing metadata to be
possible active keys. This has been fixed. [GL #2406]
5572. [bug] Address potential double free in generatexml().
[GL #2420]
5571. [bug] named failed to start when its configuration included a
zone with a non-builtin "allow-update" ACL attached.
[GL #2413]
5570. [bug] Improve performance of the DNSSEC verification code by
reducing the number of repeated calls to
dns_dnssec_keyfromrdata(). [GL #2073]
5569. [bug] Emit useful error message when "rndc retransfer" is
applied to a zone of inappropriate type. [GL #2342]
5568. [bug] Fixed a crash in "dnssec-keyfromlabel" when using ECDSA
keys. [GL #2178]
5567. [bug] Dig now reports unknown dash options while pre-parsing
the options. This prevents "-multi" instead of "+multi"
from reporting memory usage before ending option parsing
with "Invalid option: -lti". [GL #2403]
5566. [func] Add "stale-answer-client-timeout" option, which is the
amount of time a recursive resolver waits before
attempting to answer the query using stale data from
cache. [GL #2247]
5565. [func] The SONAMEs for BIND 9 libraries now include the current
BIND 9 version number, in an effort to tightly couple
internal libraries with a specific release. [GL #2387]
5562. [security] Fix off-by-one bug in ISC SPNEGO implementation.
(CVE-2020-8625) [GL #2354]
5561. [bug] KASP incorrectly set signature validity to the value of
the DNSKEY signature validity. This is now fixed.
[GL #2383]
5560. [func] The default value of "max-stale-ttl" has been changed
from 12 hours to 1 day and the default value of
"stale-answer-ttl" has been changed from 1 second to 30
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]
Merge conflicts
--- 9.16.3 released ---
5404. [bug] 'named-checkconf -z' could incorrectly indicate
success if errors were found in one view but not in a
subsequent one. [GL #1807]
5403. [func] Do not set UDP receive/send buffer sizes - use system
defaults. [GL #1713]
5402. [bug] On FreeBSD, use SO_REUSEPORT_LB instead of SO_REUSEPORT.
Enable use of SO_REUSEADDR on all platforms which
support it. [GL !3365]
5401. [bug] The number of input queues allocated during dnstap
initialization was too low, which could prevent some
dnstap data from being logged. [GL #1795]
5400. [func] Add engine support to OpenSSL EdDSA implementation.
[GL #1763]
5399. [func] Add engine support to OpenSSL ECDSA implementation.
[GL #1534]
5398. [bug] Named could fail to restart if a zone with a double
quote (") in its name was added with 'rndc addzone'.
[GL #1695]
5397. [func] Update PKCS#11 EdDSA implementation to PKCS#11 v3.0.
Thanks to Aaron Thompson. [GL !3326]
5396. [func] When necessary (i.e. in libuv >= 1.37), use the
UV_UDP_RECVMMSG flag to enable recvmmsg() support in
libuv. [GL #1797]
5395. [security] Further limit the number of queries that can be
triggered from a request. Root and TLD servers
are no longer exempt from max-recursion-queries.
Fetches for missing name server address records
are limited to 4 for any domain. (CVE-2020-8616)
[GL #1388]
5394. [cleanup] Named formerly attempted to change the effective UID and
GID in named_os_openfile(), which could trigger a
spurious log message if they were already set to the
desired values. This has been fixed. [GL #1042]
[GL #1090]
5392. [bug] It was possible for named to crash during shutdown
or reconfiguration if an RPZ zone was still being
updated. [GL #1779]
5390. [security] Replaying a TSIG BADTIME response as a request could
trigger an assertion failure. (CVE-2020-8617)
[GL #1703]
5389. [bug] Finish PKCS#11 code cleanup, fix a couple of smaller
bugs and use PKCS#11 v3.0 EdDSA macros and constants.
Thanks to Aaron Thompson. [GL !3391]
5387. [func] Warn about AXFR streams with inconsistent message IDs.
[GL #1674]
5386. [cleanup] Address Coverity warnings in lib/dns/keymgr.c.
[GL #1737]
5385. [func] Make ISC rwlock implementation the default again.
[GL #1753]
5384. [bug] With "dnssec-policy" in effect, "inline-signing" was
implicitly set to "yes". Now "inline-signing" is only
set to "yes" if the zone is not dynamic. [GL #1709]
--- 9.16.2 released ---
5383. [func] Add a quota attach function with a callback and clean up
the isc_quota API. [GL !3280]
5382. [bug] Use clock_gettime() instead of gettimeofday() for
isc_stdtime() function. [GL #1679]
5381. [bug] Fix logging API data race by adding rwlock and caching
logging levels in stdatomic variables to restore
performance to original levels. [GL #1675] [GL #1717]
5380. [contrib] Fix building MySQL DLZ modules against MySQL 8
libraries. [GL #1678]
5378. [bug] Receiving invalid DNS data was triggering an assertion
failure in nslookup. [GL #1652]
5376. [bug] Fix ineffective DNS rebinding protection when BIND is
configured as a forwarding DNS server. Thanks to Tobias
Klein. [GL #1574]
5375. [test] Fix timing issues in the "kasp" system test. [GL #1669]
5374. [bug] Statistics counters tracking recursive clients and
active connections could underflow. [GL #1087]
5373. [bug] Collecting statistics for DNSSEC signing operations
(change 5254) caused an array of significant size (over
100 kB) to be allocated for each configured zone. Each
of these arrays is tracking all possible key IDs; this
could trigger an out-of-memory condition on servers with
a high enough number of zones configured. Fixed by
tracking up to four keys per zone and rotating counters
when keys are replaced. This fixes the immediate problem
of high memory usage, but should be improved in a future
release by growing or shrinking the number of keys to
track upon key rollover events. [GL #1179]
5372. [bug] Fix migration from existing DNSSEC key files
("auto-dnssec maintain") to "dnssec-policy". [GL #1706]
5371. [bug] Improve incremental updates of the RPZ summary
database to reduce delays that could occur when
a policy zone update included a large number of
record deletions. [GL #1447]
5370. [bug] Deactivation of a netmgr handle associated with a
socket could be skipped in some circumstances.
Fixed by deactivating the netmgr handle before
scheduling the asynchronous close routine. [GL #1700]
5368. [bug] Named failed to restart if 'rndc addzone' names
contained special characters (e.g. '/'). [GL #1655]
5367. [bug] Fixed a flaw in the calculation of the zone database
size so that "max-journal-size default" uses the correct
limit. [GL #1661]
--- 9.16.1 released ---
5366. [bug] Fix a race condition with the keymgr when the same
zone plus dnssec-policy is configured in multiple
views. [GL #1653]
5365. [bug] Algorithm rollover was stuck on submitting DS
because keymgr thought it would move to an invalid
state. Fixed by checking the current key against
the desired state, not the existing state. [GL #1626]
5364. [bug] Algorithm rollover waited too long before introducing
zone signatures. It waited to make sure all signatures
were regenerated, but when introducing a new algorithm,
all signatures are regenerated immediately. Only
add the sign delay if there is a predecessor key.
[GL #1625]
5363. [bug] When changing a dnssec-policy, existing keys with
properties that no longer match were not being retired.
[GL #1624]
5361. [bug] named might not accept new connections after
hitting tcp-clients quota. [GL #1643]
5360. [bug] delv could fail to load trust anchors in DNSKEY
format. [GL #1647]
5358. [bug] Inline master zones whose master files were touched
but otherwise unchanged and were subsequently reloaded
may have stopped re-signing. [GL !3135]
5357. [bug] Newly added RRSIG records with expiry times before
the previous earliest expiry times might not be
re-signed in time. This was a side effect of 5315.
[GL !3137]
--- 9.16.0 released ---
5356. [func] Update dnssec-policy configuration statements:
- Rename "zone-max-ttl" dnssec-policy option to
"max-zone-ttl" for consistency with the existing
zone option.
- Allow for "lifetime unlimited" as a synonym for
"lifetime PT0S".
- Make "key-directory" optional.
- Warn if specifying a key length does not make
sense; fail if key length is out of range for
the algorithm.
- Allow use of mnemonics when specifying key
algorithm (e.g. "rsasha256", "ecdsa384", etc.).
- Make ISO 8601 durations case-insensitive.
[GL #1598]
5355. [func] What was set with --with-tuning=large option in
older BIND9 versions is now a default, and
a --with-tuning=small option was added for small
(e.g. OpenWRT) systems. [GL !2989]
5354. [bug] dnssec-policy created new KSK keys for zones in the
initial stage of signing (with the DS not yet in the
rumoured or omnipresent states). Fix by checking the
key goals rather than the active state when determining
whether new keys are needed. [GL #1593]
5353. [doc] Document port and dscp parameters in forwarders
configuration option. [GL #914]
5352. [bug] Correctly handle catalog zone entries containing
characters that aren't legal in filenames. [GL #1592]
5351. [bug] CDS / CDNSKEY consistency checks failed to handle
removal records. [GL #1554]
5350. [bug] When a view was configured with class CHAOS, the
server could crash while processing a query for a
non-existent record. [GL #1540]
5349. [bug] Fix a race in task_pause/unpause. [GL #1571]
5348. [bug] dnssec-settime -Psync was not being honoured.
[GL !2925]
--- 9.15.8 released ---
5347. [bug] Fixed a bug that could cause an intermittent crash
in validator.c when validating a negative cache
entry. [GL #1561]
5346. [bug] Make hazard pointer array allocations dynamic, fixing
a bug that caused named to crash on machines with more
than 40 cores. [GL #1493]
5345. [func] Key-style trust anchors and DS-style trust anchors
can now both be used for the same name. [GL #1237]
5344. [bug] Handle accept() errors properly in netmgr. [GL !2880]
5343. [func] Add statistics counters to the netmgr. [GL #1311]
5342. [bug] Disable pktinfo for IPv6 and bind to each interface
explicitly instead, because libuv doesn't support
pktinfo control messages. [GL #1558]
5341. [func] Simplify passing the bound TCP socket to child
threads by using isc_uv_export/import functions.
[GL !2825]
5340. [bug] Don't deadlock when binding to a TCP socket fails.
[GL #1499]
5339. [bug] With some libmaxminddb versions, named could erroneously
match an IP address not belonging to any subnet defined
in a given GeoIP2 database to one of the existing
entries in that database. [GL #1552]
5338. [bug] Fix line spacing in `rndc secroots`.
Thanks to Tony Finch. [GL !2478]
5337. [func] 'named -V' now reports maxminddb and protobuf-c
versions. [GL !2686]
--- 9.15.7 released ---
5336. [bug] The TCP high-water statistic could report an
incorrect value on startup. [GL #1392]
5335. [func] Make TCP listening code multithreaded. [GL !2659]
5334. [doc] Update documentation with dnssec-policy clarifications.
Also change some defaults. [GL !2711]
5333. [bug] Fix duration printing on Solaris when value is not
an ISO 8601 duration. [GL #1460]
5332. [func] Renamed "dnssec-keys" configuration statement
to the more descriptive "trust-anchors". [GL !2702]
5331. [func] Use compiler-provided mechanisms for thread local
storage, and make the requirement for such mechanisms
explicit in configure. [GL #1444]
5330. [bug] 'configure --without-python' was ineffective if
PYTHON was set in the environment. [GL #1434]
5329. [bug] Reconfiguring named caused memory to be leaked when any
GeoIP2 database was in use. [GL #1445]
5328. [bug] rbtdb.c:rdataset_{get,set}ownercase failed to obtain
a node lock. [GL #1417]
5327. [func] Added a statistics counter to track queries
dropped because the recursive-clients quota was
exceeded. [GL #1399]
5326. [bug] Add Python dependency on 'distutils.core' to configure.
'distutils.core' is required for installation.
[GL #1397]
5325. [bug] Addressed several issues with TCP connections in
the netmgr: restored support for TCP connection
timeouts, restored TCP backlog support, actively
close all open sockets during shutdown. [GL #1312]
5324. [bug] Change the category of some log messages from general
to the more appropriate catergory of xfer-in. [GL #1394]
5323. [bug] Fix a bug in DNSSEC trust anchor verification.
[GL !2609]
5322. [placeholder]
5321. [bug] Obtain write lock before updating version->records
and version->bytes. [GL #1341]
5320. [cleanup] Silence TSAN on header->count. [GL #1344]
--- 9.15.6 released ---
5319. [func] Trust anchors can now be configured using DS
format to represent a key digest, by using the
new "initial-ds" or "static-ds" keywords in
the "dnssec-keys" statement.
Note: DNSKEY-format and DS-format trust anchors
cannot both be used for the same domain name.
[GL #622]
5318. [cleanup] The DNSSEC validation code has been refactored
for clarity and to reduce code duplication.
[GL #622]
5317. [func] A new asynchronous network communications system
based on libuv is now used for listening for
incoming requests and responding to them. (The
old isc_socket API remains in use for sending
iterative queries and processing responses; this
will be changed too in a later release.)
This change will make it easier to improve
performance and implement new protocol layers
(e.g., DNS over TLS) in the future. [GL #29]
5316. [func] A new "dnssec-policy" option has been added to
named.conf to implement a key and signing policy
(KASP) for zones. When this option is in use,
named can generate new keys as needed and
automatically roll both ZSK and KSK keys. (Note
that the syntax for this statement differs from
the dnssec policy used by dnssec-keymgr.)
See the ARM for configuration details. [GL #1134]
5315. [bug] Apply the initial RRSIG expiration spread fixed
to all dynamically created records in the zone
including NSEC3. Also fix the signature clusters
when the server has been offline for prolonged
period of times. [GL #1256]
5314. [func] Added a new statistics variable "tcp-highwater"
that reports the maximum number of simultaneous TCP
clients BIND has handled while running. [GL #1206]
5313. [bug] The default GeoIP2 database location did not match
the ARM. 'named -V' now reports the default
location. [GL #1301]
5312. [bug] Do not flush the cache for `rndc validation status`.
Thanks to Tony Finch. [GL !2462]
5311. [cleanup] Include all views in output of `rndc validation status`.
Thanks to Tony Finch. [GL !2461]
5310. [bug] TCP failures were affecting EDNS statistics. [GL #1059]
5309. [placeholder]
5308. [bug] Don't log DNS_R_UNCHANGED from sync_secure_journal()
at ERROR level in receive_secure_serial(). [GL #1288]
5307. [bug] Fix hang when named-compilezone output is sent to pipe.
Thanks to Tony Finch. [GL !2481]
5306. [security] Set a limit on number of simultaneous pipelined TCP
queries. (CVE-2019-6477) [GL #1264]
5305. [bug] NSEC Aggressive Cache ("synth-from-dnssec") has been
disabled by default because it was found to have
a significant performance impact on the recursive
service. [GL #1265]
5304. [bug] "dnskey-sig-validity 0;" was not being accepted.
[GL #876]
5303. [placeholder]
5302. [bug] Fix checking that "dnstap-output" is defined when
"dnstap" is specified in a view. [GL #1281]
5301. [bug] Detect partial prefixes / incomplete IPv4 address in
acls. [GL #1143]
5300. [bug] dig/mdig/delv: Add a colon after EDNS option names,
even when the option is empty, to improve
readability and allow correct parsing of YAML
output. [GL #1226]
--- 9.15.5 released ---
5299. [security] A flaw in DNSSEC verification when transferring
mirror zones could allow data to be incorrectly
marked valid. (CVE-2019-6475) [GL #1252]
5298. [security] Named could assert if a forwarder returned a
referral, rather than resolving the query, when QNAME
minimization was enabled. (CVE-2019-6476) [GL #1051]
5297. [bug] Check whether a previous QNAME minimization fetch
is still running before starting a new one; return
SERVFAIL and log an error if so. [GL #1191]
5296. [placeholder]
5295. [cleanup] Split dns_name_copy() calls into dns_name_copy() and
dns_name_copynf() for those calls that can potentially
fail and those that should not fail respectively.
[GL !2265]
5294. [func] Fallback to ACE name on output in locale, which does not
support converting it to unicode. [GL #846]
5293. [bug] On Windows, named crashed upon any attempt to fetch XML
statistics from it. [GL #1245]
5292. [bug] Queue 'rndc nsec3param' requests while signing inline
zone changes. [GL #1205]
--- 9.15.4 released ---

5289. [bug] Address NULL pointer dereference in rpz.c:rpz_detach.
[GL #1210]
5288. [bug] dnssec-must-be-secure was not always honored.
[GL #1209]
5287. [placeholder]
5286. [contrib] Address potential NULL pointer dereferences in
dlz_mysqldyn_mod.c. [GL #1207]
5285. [port] win32: implement "-T maxudpXXX". [GL #837]
5284. [func] Added +unexpected command line option to dig.
By default, dig won't accept a reply from a source
other than the one to which it sent the query.
Invoking dig with +unexpected argument will allow it
to process replies from unexpected sources.
5283. [bug] When a response-policy zone expires, ensure that
its policies are removed from the RPZ summary
database. [GL #1146]
5282. [bug] Fixed a bug in searching for possible wildcard matches
for query names in the RPZ summary database. [GL #1146]
5281. [cleanup] Don't escape commas when reporting named's command
line. [GL #1189]
5280. [protocol] Add support for displaying EDNS option LLQ. [GL #1201]
5279. [bug] When loading, reject zones containing CDS or CDNSKEY
RRsets at the zone apex if they would cause DNSSEC
validation failures if published in the parent zone
as the DS RRset. [GL #1187]
5278. [func] Add YAML output formats for dig, mdig and delv;
use the "+yaml" option to enable. [GL #1145]
--- 9.15.3 released ---
5277. [bug] Cache DB statistics could underflow when serve-stale
was in use, because of a bug in counter maintenance
when RRsets become stale.
Functions for dumping statistics have been updated
to dump active, stale, and ancient statistic
counters. Ancient RRset counters are prefixed
with '~'; stale RRset counters are still prefixed
with '#'. [GL #602]
5276. [func] DNSSEC Lookaside Validation (DLV) is now obsolete;
all code enabling its use has been removed from the
validator, "delv", and the DNSSEC tools. [GL #7]
5275. [bug] Mark DS records included in referral messages
with trust level "pending" so that they can be
validated and cached immediately, with no need to
re-query. [GL #964]
5274. [bug] Address potential use after free race when shutting
down rpz. [GL #1175]
5273. [bug] Check that bits [64..71] of a dns64 prefix are zero.
[GL #1159]
5272. [cleanup] Remove isc-config.sh script as the BIND 9 libraries
are now purely internal. [GL #1123]
5271. [func] The normal (non-debugging) output of dnssec-signzone
and dnssec-verify tools now goes to stdout, instead of
the combination of stderr and stdout.
5270. [bug] 'dig +expandaaaa +short' did not work. [GL #1152]
5269. [port] cygwin: can return ETIMEDOUT on connect() with a
non-blocking socket. [GL #1133]
5268. [placeholder]
5267. [func] Allow statistics groups display to be toggle-able.
[GL #1030]
5266. [bug] named-checkconf failed to report dnstap-output
missing from named.conf when dnstap was specified.
[GL #1136]
5265. [bug] DNS64 and RPZ nodata (CNAME *.) rules interacted badly
[GL #1106]
5264. [func] New DNS Cookie algorithm - siphash24 - has been added
to BIND 9, and the old HMAC-SHA DNS Cookie algorithms
have been removed. [GL #605]
--- 9.15.2 released ---
5263. [cleanup] Use atomics and isc_refcount_t wherever possible.
[GL #1038]
5262. [func] Removed support for the legacy GeoIP API. [GL #1112]
5261. [cleanup] Remove SO_BSDCOMPAT socket option usage.
5260. [bug] dnstap-read was producing malformed output for large
packets. [GL #1093]
5259. [func] New option '-i' for 'named-checkconf' to ignore
warnings about deprecated options. [GL #1101]
5258. [func] Added support for the GeoIP2 API from MaxMind. This
will be compiled in by default if the "libmaxminddb"
library is found at compile time, but can be
suppressed using "configure --disable-geoip".
Certain geoip ACL settings that were available with
legacy GeoIP are not available when using GeoIP2.
[GL #182]
5257. [bug] Some statistics data was not being displayed.
Add shading to the zone tables. [GL #1030]
5256. [bug] Ensure that glue records are included in root
priming responses if "minimal-responses" is not
set to "yes". [GL #1092]
5255. [bug] Errors encountered while reloading inline-signing
zones could be ignored, causing the zone content to
be left in an incompletely updated state rather than
reverted. [GL #1109]
5254. [func] Collect metrics to report to the statistics-channel
DNSSEC signing operations (dnssec-sign) and refresh
operations (dnssec-refresh) per zone and per keytag.
[GL #513]
5253. [port] Support platforms that don't define ULLONG_MAX.
[GL #1098]
5252. [func] Report if the last 'rndc reload/reconfig' failed in
rndc status. [GL !2040]
5251. [bug] Statistics were broken in x86 Windows builds.
[GL #1081]
5250. [func] The default size for RSA keys is now 2048 bits,
for both ZSKs and KSKs. [GL #1097]
5249. [bug] Fix a possible underflow in recursion clients
statistics when hitting recursive clients
soft quota. [GL #1067]
--- 9.15.1 released ---
5248. [func] To clarify the configuration of DNSSEC keys,
the "managed-keys" and "trusted-keys" options
have both been deprecated. The new "dnssec-keys"
statement can now be used for all trust anchors,
with the keywords "iniital-key" or "static-key"
to indicate whether the configured trust anchor
should be used for initialization of RFC 5011 key
management, or as a permanent trust anchor.
The "static-key" keyword will generate a warning if
used for the root zone.
Configurations using "trusted-keys" or "managed-keys"
will continue to work with no changes, but will
generate warnings in the log. In a future release,
these options will be marked obsolete. [GL #6]
5247. [cleanup] The 'cleaning-interval' option has been removed.
[GL !1731]
5246. [func] Log TSIG if appropriate in 'sending notify to' message.
[GL #1058]
5245. [cleanup] Reduce logging level for IXFR up-to-date poll
responses. [GL #1009]
5244. [security] Fixed a race condition in dns_dispatch_getnext()
that could cause an assertion failure if a
significant number of incoming packets were
rejected. (CVE-2019-6471) [GL #942]
5243. [bug] Fix a possible race between dispatcher and socket
code in a high-load cold-cache resolver scenario.
[GL #943]
5242. [bug] In relaxed qname minimization mode, fall back to
normal resolution when encountering a lame
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]
5239. [func] Change the json-c detection to pkg-config. [GL #855]
5238. [bug] Fix a possible deadlock in TCP code. [GL #1046]

[GL #1028]
5236. [func] Add SipHash 2-4 implementation in lib/isc/siphash.c
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]
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]
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]

5204. [test] Check that dns_rdata_fromtext() produces a record that
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]
5201. [bug] Fix a possible deadlock in RPZ update code. [GL #973]
5200. [security] tcp-clients settings could be exceeded in some cases,
which could lead to exhaustion of file descriptors.
(CVE-2018-5743) [GL #615]
5199. [security] In certain configurations, named could crash
if nxdomain-redirect was in use and a redirected
query resulted in an NXDOMAIN from the cache.
(CVE-2019-6467) [GL #880]
5198. [bug] If a fetch context was being shut down and, at the same
time, we returned from qname minimization, an INSIST
could be hit. [GL #966]
5197. [bug] dig could die in best effort mode on multiple SIG(0)
records. Similarly on multiple OPT and multiple TSIG
records. [GL #920]
5196. [bug] make install failed with --with-dlopen=no. [GL #955]
5195. [bug] "allow-update" and "allow-update-forwarding" were
treated as configuration errors if used at the
options or view level. [GL #913]
5194. [bug] Enforce non empty ZOMEMD hash. [GL #899]

[GL #806]
5189. [cleanup] Remove revoked root DNSKEY from bind.keys. [GL #945]
5188. [func] The "dnssec-enable" option is deprecated and no
longer has any effect; DNSSEC responses are
always enabled. [GL #866]
5187. [test] Set time zone before running any tests in dnstap_test.
[GL #940]
5186. [cleanup] More dnssec-keygen manual tidying. [GL !1678]
5185. [placeholder]
5184. [bug] Missing unlocks in sdlz.c. [GL #936]
5183. [bug] Reinitialize ECS data before reusing client
structures. [GL #881]
5182. [bug] Fix a high-load race/crash in handling of
isc_socket_close() in resolver. [GL #834]
5181. [func] Add a mechanism for a DLZ module to signal that
the view's allow-transfer ACL should be used to
determine whether transfers are allowed. [GL #803]
5180. [bug] delv now honors the operating system's preferred
ephemeral port range. [GL #925]
5179. [cleanup] Replace some vague type declarations with the more
specific dns_secalg_t and dns_dsdigest_t.
Thanks to Tony Finch. [GL !1498]
5178. [bug] Handle EDQUOT (disk quota) and ENOSPC (disk full)
errors when writing files. [GL #902]
5177. [func] Add the ability to specify in named.conf whether a
response-policy zone's SOA record should be added
to the additional section (add-soa yes/no). [GL #865]
5176. [tests] Remove a dependency on libxml in statschannel system
test. [GL #926]
5175. [bug] Fixed a problem with file input in dnssec-keymgr,
dnssec-coverage and dnssec-checkds when using
python3. [GL #882]
5174. [doc] Tidy dnssec-keygen manual. [GL !1557]
5173. [bug] Fixed a race in socket code that could occur when
accept, send, or recv were called from an event
loop but the socket had been closed by another
thread. [RT #874]
5172. [bug] nsupdate now honors the operating system's preferred
ephemeral port range. [GL #905]
5171. [func] named plugins are now installed into a separate
directory. Supplying a filename (a string without path
separators) in a "plugin" configuration stanza now
causes named to look for that plugin in that directory.
[GL #878]
5170. [test] Added --with-dlz-filesystem to feature-test. [GL !1587]
5169. [bug] The presence of certain types in an otherwise
empty node could cause a crash while processing a
type ANY query. [GL #901]
5168. [bug] Do not crash on shutdown when RPZ fails to load. Also,
keep previous version of the database if RPZ fails to

5161. [bug] Do not require the SEP bit to be set for mirror zone
trust anchors. [GL #873]
5160. [contrib] Added DNAME support to the DLZ LDAP schema. Also
fixed a compilation bug affecting several DLZ
modules. [GL #872]
5159. [bug] dnssec-coverage was incorrectly ignoring
names specified on the command line without
trailing dots. [GL !1478]
5158. [protocol] Add support for AMTRELAY and ZONEMD. [GL #867]
5157. [bug] Nslookup now errors out if there are extra command
line arguments. [GL #207]
5156. [doc] Extended and refined the section of the ARM describing
mirror zones. [GL #774]
5155. [func] "named -V" now outputs the default paths to
named.conf, rndc.conf, bind.keys, and other
files used or created by named and other tools, so
that the correct paths to these files can quickly be
determined regardless of the configure settings
used when BIND was built. [GL #859]
5154. [bug] dig: process_opt could be called twice on the same
message leading to a assertion failure. [GL #860]
5153. [func] Zone transfer statistics (size, number of records, and
number of messages) are now logged for outgoing
transfers as well as incoming ones. [GL #513]
5152. [func] Improved logging of DNSSEC key events:
- Zone signing and DNSKEY maintenance events are
now logged to the "dnssec" category
- Messages are now logged when DNSSEC keys are
published, activated, inactivated, deleted,
or revoked.
[GL #714]
5151. [func] Options that have been been marked as obsolete in
named.conf for a very long time are now fatal
configuration errors. [GL #358]
5150. [cleanup] Remove the ability to compile BIND with assertions
disabled. [GL #735]
5149. [func] "rndc dumpdb" now prints a line above a stale RRset
indicating how long the data will be retained in the
cache for emergency use. [GL #101]
5148. [bug] named did not sign the TKEY response. [GL #821]
5147. [bug] dnssec-keymgr: Add a five-minute margin to better
handle key events close to 'now'. [GL #848]
5146. [placeholder]
5145. [func] Use atomics instead of locked variables for isc_quota
and isc_counter. [GL !1389]
5144. [bug] dig now returns a non-zero exit code when a TCP
connection is prematurely closed by a peer more than
once for the same lookup. [GL #820]
5143. [bug] dnssec-keymgr and dnssec-coverage failed to find
key files for zone names ending in ".". [GL #560]
5142. [cleanup] Removed "configure --disable-rpz-nsip" and
"--disable-rpz-nsdname" options. "nsip-enable"
and "nsdname-enable" both now default to yes,
regardless of compile-time settings. [GL #824]
5141. [security] Zone transfer controls for writable DLZ zones were
not effective as the allowzonexfr method was not being
called for such zones. (CVE-2019-6465) [GL #790]
5140. [bug] Don't immediately mark existing keys as inactive and
deleted when running dnssec-keymgr for the first
time. [GL #117]
5139. [bug] If possible, don't use forwarders when priming.
This ensures we can get root server IP addresses
from priming query response glue, which may not
be present if the forwarding server is returning
minimal responses. [GL #752]
5138. [bug] Under some circumstances named could hit an assertion
failure when doing qname minimization when using
forwarders. [GL #797]
5137. [func] named now logs messages whenever a mirror zone becomes
usable or unusable for resolution purposes. [GL #818]
5136. [cleanup] Check in named-checkconf that allow-update and
allow-update-forwarding are not set at the
view/options level; fix documentation. [GL #512]
5135. [port] sparc: Use smt_pause() instead of pause. [GL #816]
5134. [bug] win32: WSAStartup was not called before getservbyname
