that libc provides. XXX: Perhaps it is better to just make irs a private
library since not many things use it, and it is so small after we removed
the stuff that is provided by libc.

[RT #35128]
3803. [bug] "named-checkconf -z" incorrectly rejected zones
using alternate data sources for not having a "file"

mistake.
--- 9.10.0b2 released ---
3787. [bug] The code that checks whether "auto-dnssec" is
allowed was ignoring "allow-update" ACLs set at
the options or view level. [RT #29536]
3786. [func] Provide more detailed error codes when using
native PKCS#11. "pkcs11-tokens" now fails robustly
rather than asserting when run against an HSM with
an incomplete PKCS#11 API implementation. [RT #35479]
3785. [bug] Debugging code dumphex didn't accept arbitrarily long
input (only compiled with -DDEBUG). [RT #35544]
3784. [bug] Using "rrset-order fixed" when it had not been
enabled at compile time caused inconsistent
results. It now works as documented, defaulting
to cyclic mode. [RT #28104]
3783. [func] "tsig-keygen" is now available as an alternate
command name for "ddns-confgen". It generates
a TSIG key in named.conf format without comments.
[RT #35503]
3782. [func] Specifying "auto" as the salt when using
"rndc signing -nsec3param" causes named to
generate a 64-bit salt at random. [RT #35322]
3781. [tuning] Use adaptive mutex locks when available; this
has been found to improve performance under load
on many systems. "configure --with-locktype=standard"
restores conventional mutex locks. [RT #32576]
3780. [bug] $GENERATE handled negative numbers incorrectly.
[RT #25528]
3779. [cleanup] Clarify the error message when using an option
that was not enabled at compile time. [RT #35504]
3778. [bug] Log a warning when the wrong address family is
used in "listen-on" or "listen-on-v6". [RT #17848]
3777. [bug] EDNS EXPIRE code could dump core when processing
DLZ queries. [RT #35493]
3776. [func] "rndc -q" suppresses output from successful
rndc commands. Errors are printed on stderr.
[RT #21393]
3775. [bug] dlz_dlopen driver could return the wrong error
code on API version mismatch, leading to a segfault.
[RT #35495]
3774. [func] When using "request-nsid", log the NSID value in
printable form as well as hex. [RT #20864]
3773. [func] "host", "nslookup" and "nsupdate" now have
options to print the version number and exit.
[RT #26057]
3772. [contrib] Added sqlite3 dynamically-loadable DLZ module.
(Based in part on a contribution from Tim Tessier.)
[RT #20822]
3771. [cleanup] Adjusted log level for "using built-in key"
messages. [RT #24383]
3770. [bug] "dig +trace" could fail with an assertion when it
needed to fall back to TCP due to a truncated
response. [RT #24660]
3769. [doc] Improved documentation of "rndc signing -list".
[RT #30652]
3768. [bug] "dnssec-checkds" was missing the SHA-384 digest
algorithm. [RT #34000]
3767. [func] Log explicitly when using rndc.key to configure
command channel. [RT #35316]
3766. [cleanup] Fixed problems with building outside the source
tree when using native PKCS#11. [RT #35459]
3765. [bug] Fixed a bug in "rndc secroots" that could crash
named when dumping an empty keynode. [RT #35469]
3764. [bug] The dnssec-keygen/settime -S and -i options
(to set up a successor key and set the prepublication
interval) were missing from dnssec-keyfromlabel.
[RT #35394]
3763. [bug] delve: Cache DNSSEC records to avoid the need to
re-fetch them when restarting validation. [RT #35476]
3762. [bug] Address build problems with --pkcs11-native +
--with-openssl with ECDSA support. [RT #35467]
3761. [bug] Address dangling reference bug in dns_keytable_add.
[RT #35471]
3760. [bug] Improve SIT with native PKCS#11 and on Windows.
[RT #35433]
3759. [port] Enable delve on Windows. [RT #35441]
3758. [port] Enable export library APIs on Windows. [RT #35382]
3757. [port] Enable Python tools (dnssec-coverage,
dnssec-checkds) to run on Windows. [RT #34355]
3756. [bug] GSSAPI Kerberos realm checking was broken in
check_config leading to spurious messages being
logged. [RT #35443]
Move all the reference manuals to subdirs of /usr/share/doc/reference.
We have subdirs ref1-ref9, corresponding to man page sections 1-9.
Everything that's the reference manual for a program (sections 1, 6,
8), C interface (sections 2, 3), driver or file system (section 4),
format or configuration (section 5), or kernel internal interface
(section 9) belongs in here.
Section 7 is a little less clear: some things that might go in section
7 if they were a man page aren't really reference manuals. So I'm only
putting things in reference section 7 that are (to me) clearly
reference material, rather than e.g. tutorials, guides, FAQs, etc.
This obviously leaves some room for debate, especially without first
editing the docs with this distinction in mind, but if people hate
what I've done things can always be moved again.
Note also that while roff macro man pages traditionally go in section
7, I have put all the roff documentation (macros, tools, etc.) in one
place in reference/ref1/roff. This will make it easier to find and
also easier to edit it into some kind of coherent form.
SIGHUP,SIGINT,SIGTERM on startup, so make those also conditional to isc_bind9.
The net effect of this was that dhclient blocked the 3 signals for both
itself and its progeny so /etc/rc.d/dhclient restart would not work.

New Features
DNS Response-rate limiting (DNS RRL), which blunts the impact
of reflection and amplification attacks, is always compiled in
and no longer requires a compile-time option to enable it.
An experimental "Source Identity Token" (SIT) EDNS option is now
available. Similar to DNS Cookies (as invented by Donald Eastlake
III and described in draft-eastlake-dnsext-cookies-04), these
are designed to enable clients to detect off-path spoofed
responses, and to enable servers to detect spoofed-source queries.
Servers can be configured to send smaller responses to clients
that have not identified themselves using a SIT option, reducing
the effectiveness of amplification attacks. RRL processing has
also been updated: clients proven to be legitimate via SIT are
not subject to rate limiting. Use "configure --enable-sit" to
enable this feature in BIND 9. [RT #35389] **
A new zone file format, "map", stores zone data in a format that
can be mapped directly into memory, allowing significantly faster
zone loading. [RT #25419]
"delve" (domain entity lookup and validation engine) is a new
tool with dig-like semantics for looking up DNS data and performing
internal DNSSEC validation. This allows easy validation in
environments where the resolver may not be trustworthy, and
assists with troubleshooting of DNSSEC problems. (Note: not yet
available on Windows.) [RT #32406] **
The new "prefetch" option can improve recursive resolver
performance: when it is in use, cache records that are still
being requested by clients will automatically be refreshed from
the authoritative server before they expire, reducing or eliminating
the time window in which no answer is available in the cache.
[RT #35041]
Improved EDNS processing allows better resolver performance and
reliability over slow or lossy connections. [RT #30655]
Substantial improvements have been made in response-policy zone
(RPZ) performance. Up to 32 response-policy zones can now be
configured. Performance loss due to adding additional RPZs is
minimal.
RPZ now allows response policies to be configured based on the
IP address of the client.
ACLs can now be specified based on geographic location using the
MaxMind GeoIP databases. Use "configure --with-geoip" to enable
this feature in BIND 9. Thanks to Ken Brownfield for the
contribution. [RT #30681]
The version 3 XML schema for the statistics channel, including
new statistics and a flattened XML tree for faster parsing, is
no longer optional. The version 2 XML schema is now deprecated.
[RT #30023]
Improvements have been made to the XSL stylesheet used for XML
statistics: The stylesheet can now be cached by the browser;
section headers are omitted when the sections have no data to
display; counter readability has been improved. Also, broken-out
subgroups of XML statistics (server, zones, net, tasks, mem, and
status) can now be requested. Thanks to Timothe Litt for the
assistance. [RT #35115] [RT #35117]
The statistics channel can now provide data in JSON format as
well as XML.
Per-zone stats counters have been added to track TCP and UDP
queries. [RT #35375] **
Server-wide stats counters have been added to track EDNS options
received. [RT #35447] **
The new "in-view" zone option allows zone data to be shared
between views, so that multiple views can serve the same zones
authoritatively without storing multiple copies in memory. [RT #32968]
A new compile-time option, "configure --enable-native-pkcs11",
allows the BIND 9 cryptography functions to use the PKCS#11 API
natively, so that BIND can drive a cryptographic hardware service
module (HSM) directly instead of using a modified OpenSSL as an
intermediary. This has been tested with the Thales nShield HSM
and with SoftHSMv2 from the OpenDNSSEC project. [RT #29031]
When re-signing a zone, the new "dnssec-signzone -Q" option drops
signatures from keys that are still published but are no longer
active. Thanks to Pierre Beyssac for the contribution. [RT #34990]
New options have been added to "dnssec-coverage": -z and -k
indicate whether to limit coverage checks to ZSK's or KSK's, and
-l limits coverage checking to a specified duration. Thanks to
Peter Palfrader for the contribution. [RT #35168]
"named-checkconf -px" will print the contents of configuration
files with the shared secrets obscured, making it easier to share
configuration (e.g. when submitting a bug report) without revealing
private information. [RT #34465]
Added a "no-case-compress" ACL, which causes "named" to use
case-insensitive compression for specified clients. This is
useful when dealing with broken client implementations that use
case-sensitive name comparisons, rejecting responses that fail
to match the capitalization of the query that was sent.
"named" now preserves the capitalization of names when responding
to queries: for instance, a query for "example.com" may be
answered with "example.COM" if the name was configured that way
in the zone file. Some clients have a bug causing them to depend
on the older behavior, in which the case of the answer always
matched the case of the query, rather than the case of the name
configured in the DNS. Such clients can now be specified in the
new "no-case-compress" ACL; this will restore the older behavior
of "named" for those clients only. [RT #35300] **
On operating systems that support routing sockets, including Mac
OSX, *BSD and Linux, network interfaces are re-scanned automatically
whenever they change. Use "automatic-interface-scan no;" to
disable this feature. [RT #23027] **
Added "rndc scan" to trigger an interface scan manually. [RT #23027] **
A new compile-time option, "configure --with-tuning=3Dlarge", tunes
various compiled-in constants and default settings to values
suited to large servers with abundant memory. This can improve
performance on such servers, but will consume more memory and
may degrade performance on smaller systems. [RT #29538] **
The new "max-zone-ttl" option enforces maximum TTLs for zones.
If loading a zone containing a higher TTL, the load fails. DDNS
updates with higher TTLs are accepted but the TTL is truncated.
(Note: Currently supported for master zones only; inline-signing
slaves will be added.) [RT #38405] **
Added a new "dig +subnet" option to send an EDNS CLIENT-SUBNET
option (as described in draft-vandergaast-edns-client-subnet-02)
containing the specified address/prefix when querying. Thanks
to Wilmer van der Gaast for the contribution. [RT #35415] **
Partially implemented the EDNS EXPIRE option (as described in
draft-andrews-dnsext-expire-00). "dig +expire" sends an EXPIRE
option when querying. When this option is sent with an SOA query
to a slave zone running on a server that supports the option,
the response will report the time until the slave zone expires.
EXPIRE uses an experimental option code (65002), which is subject
to change when a permanent code is assigned by IANA. [RT #35416] **
Multiple DLZ databases can now be configured, and are searched
in order to find one that can answer an incoming query. Individual
zones can now be configured to be served from a specific DLZ
database. DLZ databases can serve zones of type "master" and
"redirect".
"named-checkzone" and "named-compilezone" can now read journal
files, allowing them to process dynamic zones without the zones
needing to be frozen first.
The "rndc" command now supports new key algorithms in addition
to HMAC-MD5, including HMAC-SHA1, -SHA224, -SHA256, -SHA384, and
-SHA512. The -A option to rndc-confgen can be used to select
the algorithm for the generated key. (The default is still
HMAC-MD5; this may change in a future release.) [RT #20363]
The internal and export versions of the BIND libraries (libisc,
libdns, etc) have been unified so that external library clients
can use the same libraries as BIND itself. [RT #33131]
Added a "Configure" script for Windows to simplify enabling or
disabling optional features. All versions of Visual Studio up
to 2013 are now supported, and support has been added for 64-bit
builds. Zip files containing pre-compiled 64-bit versions of
BIND 9 are now included with releases. [RT #34160] **
"rndc zonestatus" reports information about a specified zone.
"named" now listens on IPv6 as well as IPv4 interfaces by default.
Feature Changes
The default setting for the -U option (setting the number of UDP
listeners per interface) has been adjusted to improve performance.
[RT #35417] **
Updated zkt and nslint in the contrib directory to the newest
versions: zkt 1.1.2 and nslint-3.0a2. **
The isc_bitstring API is no longer used and has been removed
from the libisc library. [RT #35284] **
The word "never" can now be used as a synonym for "none" when
configuring key event dates in the dnssec tools. [RT #35277]
**
The new libiscpk11 library, introduced in the previous development
release to support native PKCS#11, has been merged into libisc
to simplify dependencies. [RT #35205] **
Documentation of native PKCS#11 has been expanded, specifically
to describe the new pkcs11: URI format used in key labels. [RT #35287] *=
*
The Windows installer now places files in the Program Files area
rather than system services. [RT #35361] **
The timestamps included in RRSIG records can now be read as
integers indicating the number of seconds since the UNIX epoch,
in addition to being read as formatted dates in YYYYMMDDHHMMSS
format. [RT #35185]
The irs_resconf_load() function, used for reading /etc/resolv.conf,
now returns ISC_R_FILENOTFOUND when the file is missing or
unreadable. However, it will still initialize an irs_resconf
structure as if the file had been configured with nameservers
at the IPv4 and IPv6 localhost addresses. Existing code that
uses irs_resconf_load() will need to be updated to treat
ISC_R_FILENOTFOUND as a qualified success, or it may leak memory
due to treating the result as a failure even though an irs_resconf
structure was allocated; see CHANGES for sample C code that
implements the correct behavior [RT #35194]
Bug Fixes
"dnssec-keygen" could set the publication date incorrectly when
only the activation date was specified on the command line. [RT #35278]
Fixed a type mismatch causing the ODBC DLZ driver to dump core
on 64-bit systems. [RT #35324]
Improved building with libtool. [RT #35314]
When a server is specified by name in "nsupdate", all addresses
for that name will be tried before giving up. Previously, if
the first address for the server name was not reachable the
update would fail. [RT #25784]
Fixed an assertion failure caused by using "rndc retransfer"
with inline-signing zones. [RT #35353]
Fixed a build failure from using "./configure --enable-openssl-hash".
[RT #35343]
The "delegation-only" flag now works in zones of type "forward".
(This had previously been documented to work, but this was
actually rejected by the configuration parser.) [RT #35392]
Fixed a race condition which could lead to a core dump when
destroying a resolver fetch object. [RT #35385]
Addressed a potential REQUIRE failure that could occur when
printing out an rdataset using a format that includes comment
data.
The "allow-notify" ACL formerly ignored TSIG keys; this has been
corrected. [RT #35425]
Fixed an uninitialized pointer in log.c that could potentially
have caused a core dump on some platforms. [RT #35260]
