BIND 9.7.0a1 is now available.
BIND 9.7.0a1 is the FIRST ALPHA release of BIND 9.7.0.
This is a technology preview of new functionality to be
included in BIND 9.7.0. Not all new functionality is in
place. APIs and configuration syntax are not yet frozen.
BIND 9.7 includes a number of changes from BIND 9.6 and earlier
releases. Most are intended to simplify DNSSEC configuration.
New features include:
- Simplified configuration of DNSSEC Lookaside Validation (DLV).
- Simplified configuration of Dynamic DNS, using the
"ddns-confgen" command line tool or the "ddns-autoconf"
zone option. (As a side effect, this also makes it
easier to configure automatic zone re-signing.)
- New named option "attach-cache" that allows multiple views
to share a single cache.
- New logging category "query-errors" to provide detailed
internal information about query failures, especially
about server failures.
- DNS rebinding attack prevention.
- New default values for dnssec-keygen parameters.
Additional features planned but not included in this alpha release:
- Support for RFC 5011 (automated trust anchor maintenance)
- Simplified tools for zone signing and key maintenance
- Fully automatic signing of zones

Changes since 9.6.0:
2612. [func] Add default values for the arguments to
dnssec-keygen. Without arguments, it will now
generate a 1024-bit RSASHA1 zone-signing key,
or with the -f KSK option, a 2048-bit RSASHA1
key-signing key. [RT #19300]
2611. [func] Add -l option to dnssec-dsfromkey to generate
DLV records instead of DS records. [RT #19300]
2610. [port] sunos: Change #2363 was not complete. [RT #19796]
2609. [func] Simplify the configuration of dynamic zones:
- add ddns-confgen command to generate
configuration text for named.conf
- add zone option "ddns-autoconf yes;", which
causes named to generate a TSIG session key
and allow updates to the zone using that key
- add '-l' (localhost) option to nsupdate, which
causes nsupdate to connect to a locally-running
named process using the session key generated
2608. [func] Perform post signing verification checks in
dnssec-signzone. These can be disabled with -P.
The post sign verification test ensures that for each
algorithm in use there is at least one non revoked
self signed KSK key. That all revoked KSK keys are
self signed. That all records in the zone are signed
by the algorithm. [RT #19653]
2607. [bug] named could incorrectly delete NSEC3 records for
empty nodes when processing a update request.
2606. [bug] "delegation-only" was not being accepted in
delegation-only type zones. [RT #19717]
2605. [bug] Accept DS responses from delegation only zones.
[RT # 19296]
2604. [func] Add support for DNS rebinding attack prevention through
new options, deny-answer-addresses and
deny-answer-aliases. Based on contributed code from
JD Nurmi, Google. [RT #18192]
2603. [port] win32: handle .exe extension of named-checkzone and
named-comilezone argv names under windows.
2602. [port] win32: fix debugging command line build of libisccfg.
2601. [doc] Mention file creation mode mask in the
named manual page.
2600. [doc] ARM: miscellaneous reformatting for different
page widths. [RT #19574]
2599. [bug] Address rapid memory growth when validation fails.
2598. [func] Reserve the -F flag. [RT #19657]
2597. [bug] Handle a validation failure with a insecure delegation
from a NSEC3 signed master/slave zone. [RT #19464]
2596. [bug] Stale tree nodes of cache/dynamic rbtdb could stay
long, leading to inefficient memory usage or rejecting
newer cache entries in the worst case. [RT #19563]
2595. [bug] Fix unknown extended rcodes in dig. [RT #19625]
2594. [func] Have rndc warn if using its default configuration
file when the key file also exists. [RT #19424]
2593. [bug] Improve a corner source of SERVFAILs [RT #19632]
2592. [bug] Treat "any" as a type in nsupdate. [RT #19455]
2591. [bug] named could die when processing a update in
removed_orphaned_ds(). [RT #19507]
2590. [func] Report zone/class of "update with no effect".
2589. [bug] dns_db_unregister() failed to clear '*dbimp'.
2588. [bug] SO_REUSEADDR could be set unconditionally after failure
of bind(2) call. This should be rare and mostly
harmless, but may cause interference with other
processes that happen to use the same port. [RT #19642]
2587. [func] Improve logging by reporting serial numbers for
when zone serial has gone backwards or unchanged.
2586. [bug] Missing cleanup of SIG rdataset in searching a DLZ DB
or SDB. [RT #19577]
2585. [bug] Uninitialized socket name could be referenced via a
statistics channel, triggering an assertion failure in
XML rendering. [RT #19427]
2584. [bug] alpha: gcc optimization could break atomic operations.
2583. [port] netbsd: provide a control to not add the compile
date to the version string, -DNO_VERSION_DATE.
2582. [bug] Don't emit warning log message when we attempt to
remove non-existant journal. [RT #19516]
2581. [contrib] dlz/mysql set MYSQL_OPT_RECONNECT option on connection.
Requires MySQL 5.0.19 or later. [RT #19084]
2580. [bug] UpdateRej statistics counter could be incremented twice
for one rejection. [RT #19476]
2579. [bug] DNSSEC lookaside validation failed to handle unknown
algorithms. [RT #19479]
2578. [bug] Changed default sig-signing-type to 65534, because
65535 turns out to be reserved. [RT #19477]
2577. [doc] Clarified some statistics counters. [RT #19454]
2576. [bug] NSEC record were not being correctly signed when
a zone transitions from insecure to secure.
Handle such incorrectly signed zones. [RT #19114]
2575. [func] New functions dns_name_fromstring() and
dns_name_tostring(), to simplify conversion
of a string to a dns_name structure and vice
versa. [RT #19451]
2574. [doc] Document nsupdate -g and -o. [RT #19351]
2573. [bug] Replacing a non-CNAME record with a CNAME record in a
single transaction in a signed zone failed. [RT #19397]
2572. [func] Simplify DLV configuration, with a new option
"dnssec-lookaside auto;" This is the equivalent
of "dnssec-lookaside . trust-anchor dlv.isc.org;"
plus setting a trusted-key for dlv.isc.org.
Note: The trusted key is hard-coded into named,
but is also stored in (and can be overridden
by) $sysconfdir/bind.keys. As the ISC DLV key
rolls over it can be kept up to date by replacing
the bind.keys file with a key downloaded from
https://www.isc.org/solutions/dlv. [RT #18685]
2571. [func] Add a new tool "arpaname" which translates IP addresses
to the corresponding IN-ADDR.ARPA or IP6.ARPA name.
2570. [func] Log the destination address the query was sent to.
2569. [func] Move journalprint, nsec3hash, and genrandom
commands from bin/tests into bin/tools;
"make install" will put them in $sbindir. [RT #19301]
2568. [bug] Report when the write to indicate a otherwise
successful start fails. [RT #19360]
2567. [bug] dst__privstruct_writefile() could miss write errors.
write_public_key() could miss write errors.
dnssec-dsfromkey could miss write errors.
2566. [cleanup] Clarify logged message when an insecure DNSSEC
response arrives from a zone thought to be secure:
"insecurity proof failed" instead of "not
insecure". [RT #19400]
2565. [func] Add support for HIP record. Includes new functions
and dns_rdata_hip_current(). [RT #19384]
2564. [bug] Only take EDNS fallback steps when processing timeouts.
2563. [bug] Dig could leak a socket causing it to wait forever
to exit. [RT #19359]
2562. [doc] ARM: miscellaneous improvements, reorganization,
and some new content.
2561. [doc] Add isc-config.sh(1) man page. [RT #16378]
2560. [bug] Add #include <config.h> to iptable.c. [RT #18258]
2559. [bug] dnssec-dsfromkey could compute bad DS records when
reading from a K* files. [RT #19357]
2558. [func] Set the ownership of missing directories created
for pid-file if -u has been specified on the command
line. [RT #19328]
2557. [cleanup] PCI compliance:
* new libisc log module file
* isc_dir_chroot() now also changes the working
directory to "/".
* additional INSISTs
* additional logging when files can't be removed.
2556. [port] Solaris: mkdir(2) on tmpfs filesystems does not do the
error checks in the correct order resulting in the
wrong error code sometimes being returned. [RT #19249]
2555. [func] dig: when emitting a hex dump also display the
corresponding characters. [RT #19258]
2554. [bug] Validation of uppercase queries from NSEC3 zones could

2549. [port] linux: define NR_OPEN if not currently defined.
2548. [bug] Install iterated_hash.h. [RT #19335]
2547. [bug] openssl_link.c:mem_realloc() could reference an
out-of-range area of the source buffer. New public
function isc_mem_reallocate() was introduced to address
this bug. [RT #19313]
2546. [func] Add --enable-openssl-hash configure flag to use
OpenSSL (in place of internal routine) for hash
functions (MD5, SHA and HMAC). [RT #18815]

especially with threads and smaller max-cache-size
values. [RT #19240]
2537. [func] Added more statistics counters including those on socket
I/O events and query RTT histograms. [RT #18802]
2536. [cleanup] Silence some warnings when -Werror=format-security is
specified. [RT #19083]
2535. [bug] dig +showsearch and +trace interacted badly. [RT #19091]
