BIND 10 - 1.0.0 Release Candidate
Welcome to the first release candidate toward the first production
BIND 10 1.0.0 release. BIND 10 provides a C++ library for DNS
(with python wrappers) and several cooperating daemons for providing
authoritative DNS service (with in-memory and SQLite3 backends and
DNSSEC support), dynamic DNS, zone transfers, and experimental
forwarding and recursive name service. Supplementary components
are included for statistics collection and reporting and remote
configuration and control.
This version of BIND 10 also includes the latest snapshot of the
BIND 10 DHCP development. The snapshot includes a C++ library for
DHCP and two DHCP servers, one for IPv4 and one for IPv6. Features
of these servers are:
* Able to allocate and renew addresses, and handle lease expiration
* Supports a subset of clients:
- DHCPv4 clients connected to the server via a relay.
- DHCPv6 clients on the same LAN as the server.
* Able to configure values for standard options returned to a client,
either globally or on a per-subnet basis.
* Able to define new options and configure them in the same way as
* Leases are stored in a MySQL database.
* Configuration, logging and process control uses the same mechanisms
as the BIND 10 DNS server.
Note: The default testing account and password for bindctl/b10-cmdctl
is now removed; a new account for remote configuration and control
can be created with b10-cmdctl-usermgr, for example:
b10-cmdctl-usermgr --file /usr/local/etc/bind10/cmdctl-accounts.csv
We are looking for testers to provide feedback about using this
release candidate. For more information about BIND 10, the release
schedule, and the community testing plans, please see:
Documentation is included and also available via the BIND 10 website

A summary of the significant changes since the previous release
include (from the ChangeLog):
580. [func]* muks
There is no longer a default user account. The old default account
with username 'root' has been removed. In a fresh installation of
BIND 10, the administrator has to configure a user account using
the b10-cmdctl-usermgr program.
(Trac #2641, git 54e8f4061f92c2f9e5b8564240937515efa6d934)
579. [bug] jinmei
libdatasrc/b10-auth: corrected some corner cases in query handling
of in-memory data source that led to the following invalid/odd
responses from b10-auth:
- duplicate RRs in answer and additional for type ANY query
- incorrect NSEC for no error, no data (NXRRSET) response that
matches a wildcard
(Trac #2585, git abe78fae4ba3aca5eb01806dd4e05607b1241745)
578. [bug] jinmei
b10-auth now returns closest encloser NSEC3 proof to queries for
an empty non terminal derived from an Opt-Out NSEC RR, as clarified
in errata 3441 for RFC5155. Previously it regarded such case as
broken zone and returned SERVFAIL.
(Trac #2659, git 24c235cb1b379c6472772d340e21577c3460b742)
577. [func] muks
Added an SQLite3 index on records(rname, rdtype). This decreases
insert performance by ~28% and adds about ~20% to the file size,
but increases zone iteration performance. As it introduces a new
index, a database upgrade would be required.
(Trac #1756, git 9b3c959af13111af1fa248c5010aa33ee7e307ee)
576. [bug] tmark, tomek
b10-dhcp6: Fixed bug when the server aborts operation when
receiving renew and there are no IPv6 subnets configured.
(Trac #2719, git 3132b8b19495470bbfd0f2ba0fe7da443926034b)
575. [bug] marcin
b10-dhcp6: Fixed the bug whereby the subnet for the incoming
packet was selected using only its source address. The subnet
is now selected using either source address or the name of the
server's interface on which the packet has been received.
(Trac #2704, git 1cbacf19a28bdae50bb9bd3767bca0147fde37ed)
574. [func] tmark
b10-dhcp4, b10-dhcp6: Composite key indexes were added to the lease
tables to reduce lease search time. The lease4 table now has two
additional indexes: a) hwaddr/subnet_id and b) client_id/subnet_id.
The lease6 now has the one additional index: iaid/subnet_id/duid.
Adding these indexes significantly improves lease acquisition
(Trac #2699,#2703, git 54bbed5fcbe237c5a49b515ae4c55148723406ce)
573. [bug] stephen
Fixed problem whereby the DHCP server crashed if it ran out of
addresses. Such a condition now causes a packet to be returned
to the client refusing the allocation of an address.
(Trac #2681, git 87ce14cdb121b37afb5b1931af51bed7f6323dd6)
572. [bug] marcin
perfdhcp: Fixed bug where the command line switches used to
run the perfdhcp where printed as ASCII codes.
(Trac #2700, git b8d6b949eb7f4705e32fbdfd7694ca2e6a6a5cdc)
571. [build] jinmei
The ./configure script can now handle output from python-config
--ldflags that contains a space after -L switches. This fixes
failure reported on some Solaris environments.
(Trac #2661, git e6f86f2f5eec8e6003c13d36804a767a840d96d6)
570. [bug] tmark, marcin, tomek
b10-dhcp4: Address renewal now works properly for DHCPv4 clients
that do not send client ID.
(Trac #2702, git daf2abe68ce9c111334a15c14e440730f3a085e2)
569. [bug] tomek
b10-dhcp4: Fix bug whereby a DHCP packet without a client ID
could crash the MySQL lease database backend.
(Trac #2697, git b5e2be95d21ed750ad7cf5e15de2058aa8bc45f4)
568. [func] muks
Various message IDs have been renamed to remove the word 'ERROR'
from them when they are not logged at ERROR severity level.
(Trac #2672, git 660a0d164feaf055677f375977f7ed327ead893e)
567. [doc] marcin, stephen, tomek
Update DHCP sections of the BIND 10 guide.

566. [func]* jinmei
libdns++/Python isc.dns: In Python isc.dns, function style
constants for RRType, RRClass, Rcode and Opcode were deprecated
and replaced with straightforward object constants, e.g., from
RRType.AAAA() to RRType.AAAA. This is a backward incompatible
change (see the Trac ticket for a conversion script if needed).
Also, these constants are now more consistent between C++
and Python, and RRType constants for all currently standardized
types are now supported (even if Rdata for these are not yet
(Trac #1866 and #2409, git e5005185351cf73d4a611407c2cfcd163f80e428)
565. [func]* jelte
The main initializer script (formerly known as either 'bind10',
'boss', or 'bob'), has been renamed to b10-init (and Init in
configuration). Configuring which components are run is henceforth
done through '/Init/components', and the sbin/bind10 script is now
simply a shellscript that runs b10-init. Existing configuration is
automatically updated. NOTE: once configuration with this update
has been saved (by committing any new change with bindctl), you
cannot run older versions of BIND 10 anymore with this configuration.
(Trac #1901, git bae3798603affdb276f370c1ac6b33b011a5ed4f)
564. [func] muks
libdns++: the CNAME, DNAME, MX, NS, PTR and SRV Rdata classes now
use the generic lexer in constructors from text. This means that
the name fields in such RRs in a zone file can now be non-absolute
(the origin name in that context will be used), e.g., when loaded
by b10-loadzone. One additional change to the libdns++ API is that
the existing string constructors for these Rdata classes also use
the generic lexer, and they now expect an absolute name (with the
trailing '.') in the name fields.
(Trac #2390, git a01569277cda3f78b1171bbf79f15ecf502e81e2)
(Trac #2656, git 5a0d055137287f81e23fbeedd35236fee274596d)

Added --disable-rpath configure option to avoid embedding library
paths to binaries. Patch from Adam Tkac.
(Trac #2667, git 1c50c5a6ee7e9675e3ab154f2c7f975ef519fca2)

The b10-xfrin now performs basic sanity check on just received
zone. It'll reject severely broken zones (such as missing NS
(Trac #2439, git 44699b4b18162581cd1dd39be5fb76ca536012e6)
561. [bug] kambe, jelte
b10-stats-httpd no longer dumps request information to the console,
but uses the bind10 logging system. Additionally, the logging
identifiers have been changed from STATHTTPD_* to STATSHTTPD_*
(Trac #1897, git 93716b025a4755a8a2cbf250a9e4187741dbc9bb)
560. [bug] jinmei
b10-auth now sets the TTL of SOA RR for negative responses to
the minimum of the RR TTL and the minimum TTL of the SOA RDATA
as specified in RFC2308; previously the RR TTL was always used.
The ZoneFinder class was extended partly for implementing this
and partly for allowing further optimization.
(Trac #2309 and #2635, git ee17e979fcde48b59d91c74ac368244169065f3b)
559. [bug] jelte
b10-cmdctl no longer aborts on basic file issues with its https
certificate or private key file. It performs additional checks, and
provides better error logs if these fail. Additionally, bindctl
provides a better error report if it is unable to connect over
https connection. This issue could occur if BIND 10 was installed
with root privileges but then started as a normal user.

558. [func] marcin
b10-dhcp4: server now adds configured options to its
responses to a client when client requests them.
A few basic options: Routers, Domain Name, Domain
Name Servers and Subnet Mask are added regardless
if client requested them or not.

556. [bug] marcin
Fixed DHCP servers configuration whereby the servers did not
receive a configuration stored in the database on their startup.
Also, the configuration handler function now uses full configuration
instead of partial to configure the server. This guarantees that
dependencies between various configuration parameters are

The encapsulated option space name can be specified for
a DHCP option. It comprises sub-options being sent within
an option that encapsulates this option space.

b10-loadzone: improved completion log message and intermediate
reports: It now logs the precise number of loaded RRs on
completion, and intermediate reports show additional information
such as the estimated progress in percentage and estimated time

Values of the parameters to access the DHCP server lease database
can now be set through the BIND 10 configuration mechanism.

552. [bug] shane
Build on Raspberry PI.
The main issue was use of char for reading from input streams,
which is incorrect, as EOF is returned as an int -1, which would
then get cast into a char -1.
A number of other minor issues were also fixed.

551. [bug] shane
Kill msgq if we cannot connect to it on startup.
When the boss process was unable to connect to the msgq, it would
exit. However, it would leave the msgq process running. This has
been fixed, and the msgq is now stopped in this case.

b10-dhcp4: The DHCPv4 server now generates a server identifier
the first time it is run. The identifier is preserved in a file
across server restarts.

libdns++: the SOA Rdata class now uses the generic lexer in
constructors from text. This means that the MNAME and RNAME of an
SOA RR in a zone file can now be non absolute (the origin name
in that context will be used), e.g., when loaded by b10-loadzone.

b10-dhcp4: Allocation engine support for IPv4 added. Currently
supported operations are server selection (Discover/Offer),
address assignment (Request/Ack), address renewal (Request/Ack),
and address release (Release). Expired leases can be reused.
Some options (e.g. Router Option) are still hardcoded, so the
DHCPv4 server is not yet usable, although its address allocation

Created OptionSpace and OptionSpace6 classes to represent DHCP
option spaces. The option spaces are used to group instances
and definitions of options having uniqe codes. A special type
of option space is the so-called "vendor specific option space"
which groups sub-options sent within Vendor Encapsulated Options.
The new classes are not used yet but they will be used once

DHCP Option values can be now specified using a string of
tokens separated with comma sign. Subsequent tokens are used
to set values for corresponding data fields in a particular
DHCP option. The format of the token matches the data type
of the corresponding option field: e.g. "192.168.2.1" for IPv4
address, "5" for integer value etc.

538. [bug] muks
Added escaping of special characters (double-quotes, semicolon,
backslash, etc.) in text-like RRType's toText() implementation.
Without this change, some TXT and SPF RDATA were incorrectly
stored in SQLite3 datasource as they were not escaped.

Detect a build issue on FreeBSD with g++ 4.2 and Boost installed via
FreeBSD ports at ./configure time. This seems to be a bug of
FreeBSD ports setup and has been reported to the maintainer:
Until it's fixed, you need to build BIND 10 for FreeBSD that has
this problem with specifying --without-werror, with clang++
(development version), or with manually extracted Boost header
files (no compiled Boost library is necessary).

535. [bug] jelte
The log4cplus internal logging mechanism has been disabled, and no
output from the log4cplus library itself should be printed to
stderr anymore. This output can be enabled by using the
compile-time option --enable-debug.

The b10-msgq now uses the same logging format as the rest
of the system. However, it still doesn't obey the common
