Version 4.4.2
22 January 2020
Release Notes
NEW FEATURES
Please note that that ISC DHCP is now licensed under the Mozilla Public License,
MPL 2.0. Please see https://www.mozilla.org/en-US/MPL/2.0/ to read the MPL 2.0
license terms.
While release 4.4.2 is primarily a maintenance release that addresses a number
of defects, it does introduce a few new features:
- Keama - Keama is a migration utility that assists in converting ISC DHCP
server configuration files to Kea configuration files. It is found in the
keama subdirectory and includes a README.md file with instructions on how
to build it as well as a manpage on its usage.
- Two new server parameters related to ping checking were added:
1. ping-cltt-secs which allows the user to specify the number of seconds
that must elapse since CLTT before a ping check is conducted.
2. ping-timeout-ms which allows the user to specify the amount of time the
server waits for a ping-check response in milliseconds rather than in
seconds.
In general, the areas of focus for ISC DHCP 4.4 were:
1. Dynamic DNS additions
2. dhclient improvements
3. Support for dynamic shared libraries
Dynamic DNS Improvements:
- We added three new server configuration parameters which influence DDNS
conflict resolution:
1. ddns-dual-stack-mixed-mode - alters DNS conflict resolution behavior
to mitigate issues with non-compliant clients in dual stack environments.
2. ddns-guard-id-must-match - relaxes the DHCID RR client id matching
requirement of DNS conflict resolution.
3. ddns-other-guard-is-dynamic - alters dual-stack-mixed-mode behavior to
allow unguarded DNS entries to be overwritten in certain cases
- The server now honors update-static-leases parameter for static DHCPv6
hosts.
dhclient Improvements:
- We've added three command line parameters to dhclient:
1. --prefix-len-hint - directs dhclient to use the given length as
the prefix length hint when requesting prefixes
2. --decline-wait-time - instructs the client to wait the given number
of seconds after declining an IPv4 address before issuing a discover
3. --address-prefix-len - specifies the prefix length passed by dhclient
into the client script (via the environment variable ip6_prefixlen) with
each IPv6 address. We added this parameter because we have changed the
default value from 64 to 128 in order to be compliant with RFC3315bis
draft (-09, page 64) and RFC5942, Section 4, point 1.
**WARNING**: The new default value of 128 may not be backwardly compatible
with your environment. If you are operating without a router, such as
between VMs on a host, you may find they cannot see each other with prefix
length of 128. In such cases, you'll need to either provide routing or use
the command line parameter to set the value to 64. Alternatively you may
change the default at compile time by setting DHCLIENT_DEFAULT_PREFIX_LEN
in includes/site.h.
- dhclient will now generate a DHCPv6 DECLINE message when the client script
indicates a DAD failure
Dynamic shared library support:
Configure script, configure.ac+lt, which supports libtool is now provided
with the source tar ball. This script can be used to configure ISC DHCP
to build with libtool and thus use dynamic shared libraries.
Other Highlights:
- The server now supports dhcp-cache-threshold for DHCPv6 operations
- The server now supports DHPv6 address allocation based on EUI-64 DUIDs
- Experimental support for alternate relay port in the both the server
and relay for IPv4, IPv6 and 4o6 (see: draft-ietf-dhc-relay-port-10.txt)
For information on how to install, configure and run this software, as
well as how to find documentation and report bugs, please consult the
README file.
ISC DHCP uses standard GNU configure for installation. Please review the
output of "./configure --help" to see what options are available.
The system has only been tested on Linux, FreeBSD, and Solaris, and may not
work on other platforms. Please report any problems and suggested fixes to
<dhcp-users@isc.org>.
ISC DHCP is open source software maintained by Internet Systems
Consortium. This product includes cryptographic software written
by Eric Young (eay@cryptsoft.com).
Changes since 4.4.2b1 (Bug Fixes)
- Added a clarification on DHCPINFORMs and server authority to
dhcpd.conf.5
[Gitlab #37]
- Only emit lease scrubbing log messages when DEBUG_FAILOVER_MESSAGES
is defined.
[Gitlab #72]
- Added the interface name to socket initialization failure log messages.
Prior to this the log messages stated only the error reason without
stating the target interface.
[Gitlab #75]
- Corrected buffer pointer logic in dhcrelay functions that manipulate
agent relay options. Thanks to Thomas Imbert of MSRC Vulnerabilities
& Mitigations for reporting the issue.
[#71]
- Corrected unresolved symbol errors building relay_unittests when
configured to build using libtool.
[#80]
Changes since 4.4.1 (New Features)
- A new configuration parameter, ping-cltt-secs (v4 operation only), has
been added to allow the user to specify the number of seconds that must
elapse since CLTT before a ping check is conducted. Prior to this, the
value was hard coded at 60 seconds. Please see the server man pages for
a more detailed discussion.
[ISC-Bugs #36283]
- A new configuration parameter, ping-timeout-ms (v4 operation only),
has been added that allows the user to specify the amount of time
the server waits for a ping-check response in milliseconds rather
than in seconds (via ping-timeout). When greater than zero, the value
of ping-timeout-ms will override the value of ping-timeout. Thanks
to Jay Doran from Bluecat Networks for suggesting this feature.
[Gitlab #10]
- An experimental tool called, Keama (KEA Migration Assistant), which helps
translate ISC DHCP configurations to Kea configurations, is now included
in the distribution.
[Gitlab #34]
Changes since 4.4.1 (Bug Fixes)
- Corrected a misuse of the BIND9 DDNS API which caused DDNS updates to be
carried out over TCP rather than UDP. The coding error was exposed by
migration to BIND9 9.11. Thanks to Jinmei Tatuya at Infoblox for
reporting the issue.
[ISC-Bugs #47757]
- Bind9 now defaults to requiring python to build. The Makefile for
building Bind9 when bundled with ISC DHCP was modified to turn off
this dependency.
[Gitlab #3]
- Corrected a dual-stack mixed-mode issue that occurs when both
ddns-guard-id-must-match and ddns-other-guard-is-dynamic
are enabled and that caused the server to incorrectly interpret
the presence of a guard record belonging to another client as
a case of no guard record at all. Thanks to Fernando Soto
from BlueCat Networks for reporting this issue.
[Gitlab #1]
- Corrected a compilation issue that occurred when building without DNS
update ability (e.g. by undefining NSUPDATE).
[Gitlab #16]
- Corrected an issue that was causing the server, when running in
DHPCv4 mode, to segfault when class lease limits are reached.
Thanks to Peter Nagy at Porion-Digital for reporting the matter
and submitting a patch.
[Gitlab #13]
- Made minor changes to eliminate warnings when compiled with GCC 9.
Thanks to Brett Neumeier for bringing the matter to our attention.
[Gitlab #15]
- Fixed potential memory leaks in parser error message generation
spotted by Coverity, CIDs: 1448191, 1448193, 1448194, 1448195
[Gitlab #30]
- Updated URL of IEEE oui.txt in contrib/dhcp-lease-list.pl. Thanks
to Tommy Smith for contributing the patch.
[Gitlab #26]
- Fixed define flags when using SO_BINDTODEVICE. Thanks to Joe LeVeque for
reporting the issue.
[GitLab #19]
- Applied a patch from OpenBSD to always set the scope id of outbound
DHPCv6 packets. Note this change only applies when compiling under
OpenBSD. Thanks to Brad Smith at OpenBSD from bringing it to our
attention.
[Gitlab #33]
- Modified dhclient to not discard config file leases that are
duplicates of server-provided leases and to retain such leases
after they have been used as the fallback active lease and
DHCP service has been restored. This allows them to be used
more than once during the lifetime of a dhclient instance.
This applies to DHCPv4 operation only.
[Gitlab #9]
- Corrected a number of reference counter and zero-length buffer leaks.
Thanks to Christopher Ertl of MSRC Vulnerabilities & Mitigations for
pointing them out.
[Gitlab #57]
- Closed a small window of time between the installation of graceful
shutdown signal handlers and application context startup, during which
the receipt of shutdown signal would cause a REQUIRE() assertion to
occur. Note this issue is only visible when compiling with
ENABLE_GENTLE_SHUTDOWN defined.
[Gitlab #53]
- Corrected a buffer overflow that can occur when retrieving zone
names that are more than 255 characters in length.
[Gitlab #20]
- The "d" domain name option format was incorrectly handled as text
instead of RFC 1035 wire format. Thanks to Jay Doran at BlueCat Networks
for reporting this issue.
[Gitlab #2]
- Improved the error message issued when a host declaration has both
a uid and a dhcp-client-identifier. Server configuration parsing will
now fail if a host declaration specifies more than one uid.
[Gitlab #7]
- Updated developer's documentation on building and running unit tests.
Removed support for --with-atf=bind as BIND9 no longer bundles in ATF
source.
[Gitlab #35]
- Fixed a syntax error in ldap.c which cropped up under Ubuntu
18.04.1/gcc 7.4.0. Thanks to Charles Hedrick for pointing it out.
[Gitlab #51]
- Added clarification to dhcp-options.5 section on ip-address values
describing the first-use DNS resolution of options with hostnames as
values (e.g. next-server).
[Gitlab #28]
- The option format for the server option omapi-key was changed to a
format type 'k' (key name); while server options ldap-port and
ldap-init-retry were changed to 'L' (unsigned 32-bit integer). These
three options were inadvertantly broken when the 'd' format content
was changed to comply with RFC 1035 wire format (see Gitlab #2).
[Gitlab #68]
5458. [bug] Prevent a theoretically possible NULL dereference caused
by a data race between zone_maintenance() and

[GL #1952]
5446. [bug] The validator could fail to accept a properly signed
RRset if an unsupported algorithm appeared earlier in
the DNSKEY RRset than a supported algorithm. It could
also stop if it detected a malformed public key.
[GL #1689]
5444. [bug] 'rndc dnstap -roll <value>' did not limit the number of
saved files to <value>. [GL !3728]
5443. [bug] The "primary" and "secondary" keywords, when used
as parameters for "check-names", were not
processed correctly and were being ignored. [GL #1949]
5441. [bug] ${LMDB_CFLAGS} was missing from make/includes.in.
[GL #1955]
5440. [test] Properly handle missing kyua. [GL #1950]
5439. [bug] The DS RRset returned by dns_keynode_dsset() was used in
a non-thread-safe manner. [GL #1926]

5438. [bug] Fix a race in TCP accepting code. [GL #1930]
5437. [bug] Fix a data race in lib/dns/resolver.c:log_formerr().
[GL #1808]
5436. [security] It was possible to trigger an INSIST when determining

(CVE-2020-8618) [GL #1850]
5435. [tests] Add RFC 4592 responses examples to the wildcard system
test. [GL #1718]
5434. [security] It was possible to trigger an INSIST in
lib/dns/rbtdb.c:new_reference() with a particular zone
content and query patterns. (CVE-2020-8619) [GL #1111]
[GL #1718]
5431. [func] Reject DS records at the zone apex when loading
master files. Log but otherwise ignore attempts to
add DS records at the zone apex via UPDATE. [GL #1798]
5430. [doc] Update docs - with netmgr, a separate listening socket
is created for each IPv6 interface (just as with IPv4).
[GL #1782]
5428. [bug] Clean up GSSAPI resources in nsupdate only after taskmgr
has been destroyed. Thanks to Petr Menšík. [GL !3316]
5426. [bug] Don't abort() when setting SO_INCOMING_CPU on the socket
fails. [GL #1911]
5425. [func] The default value of "max-stale-ttl" has been changed
from 1 week to 12 hours. [GL #1877]
5424. [bug] With KASP, when creating a successor key, the "goal"
state of the current active key (predecessor) was not
changed and thus never removed from the zone. [GL #1846]
5423. [bug] Fix a bug in keymgr_key_has_successor(): it incorrectly
returned true if any other key in the keyring had a
successor. [GL #1845]
5422. [bug] When using dnssec-policy, print correct key timing
metadata. [GL #1843]
5421. [bug] Fix a race that could cause named to crash when looking
up the nodename of an RBT node if the tree was modified.
[GL #1857]
5420. [bug] Add missing isc_{mutex,conditional}_destroy() calls
that caused a memory leak on FreeBSD. [GL #1893]
5418. [bug] delv failed to parse deprecated trusted-keys-style
trust anchors. [GL #1860]
5416. [bug] Fix a lock order inversion in lib/isc/unix/socket.c.
[GL #1859]
5415. [test] Address race in dnssec system test that led to
test failures. [GL #1852]
5414. [test] Adjust time allowed for journal truncation to occur
in nsupdate system test to avoid test failure.
[GL #1855]
5413. [test] Address race in autosign system test that led to
test failures. [GL #1852]
5412. [bug] 'provide-ixfr no;' failed to return up-to-date responses
when the serial was greater than or equal to the
current serial. [GL #1714]
5411. [cleanup] TCP accept code has been refactored to use a single
accept() and pass the accepted socket to child threads
for processing. [GL !3320]
5409. [performance] When looking up NSEC3 data in a zone database, skip the
check for empty non-terminal nodes; the NSEC3 tree does
not have any. [GL #1834]
5408. [protocol] Print Extended DNS Errors if present in OPT record.
[GL #1835]
5407. [func] Zone timers are now exported via statistics channel.
Thanks to Paul Frieden, Verizon Media. [GL #1232]
5405. [bug] 'named-checkconf -p' could include spurious text in
server-addresses statements due to an uninitialized DSCP
value. [GL #1812]
This logic correctly uses strncpy(3) to fully initialize a fixed-width field, and also ensures
NUL-termination on the next line as other users of the field expect.
Add -Werror=stringop-truncation to prevent build failure, when run with MKSANITIZER=yes.
Error was reported when build.sh was run with MKSANITIZER=yes flag.
Reviewed by: kamil@
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]

[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]

[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]

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]

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]

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

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

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]
