4235. [func] Added support in named for "dnstap", a fast method of
capturing and logging DNS traffic, and a new command
"dnstap-read" to read a dnstap log file. Use
"configure --enable-dnstap" to enable this
feature (note that this requires libprotobuf-c
and libfstrm). See the ARM for configuration details.
Thanks to Robert Edmonds of Farsight Security.
[RT #40211]
4224. [func] Added support for "dyndb", a new interface for loading
zone data from an external database, developed by
Red Hat for the FreeIPA project.
DynDB drivers fully implement the BIND database
API, and are capable of significantly better
performance and functionality than DLZ drivers,
while taking advantage of advanced database
features not available in BIND such as multi-master
replication.
Thanks to Adam Tkac and Petr Spacek of Red Hat.
[RT #35271]
4183. [cleanup] Use timing-safe memory comparisons in cryptographic
code. Also, the timing-safe comparison functions have
been renamed to avoid possible confusion with
memcmp(). [RT #40148]
3938. [func] Added quotas to be used in recursive resolvers
that are under high query load for names in zones
whose authoritative servers are nonresponsive or
are experiencing a denial of service attack.
- "fetches-per-server" limits the number of
simultaneous queries that can be sent to any
single authoritative server. The configured
value is a starting point; it is automatically
adjusted downward if the server is partially or
completely non-responsive. The algorithm used to
adjust the quota can be configured via the
"fetch-quota-params" option.
- "fetches-per-zone" limits the number of
simultaneous queries that can be sent for names
within a single domain. (Note: Unlike
"fetches-per-server", this value is not
self-tuning.)
- New stats counters have been added to count
queries spilled due to these quotas.
See the ARM for details of these options. [RT #37125]
experimental SIT option of BIND 9.10. The following
named.conf directives are avaliable: send-cookie,
cookie-secret, cookie-algorithm and nocookie-udp-size.
The following dig options are available:
+[no]cookie[=value] and +[no]badcookie. [RT #39928]
4005. [func] The buffer used for returning text from rndc
commands is now dynamically resizable, allowing
arbitrarily large amounts of text to be sent back
to the client. (Prior to this change, it was
possible for the output of "rndc tsig-list" to be
truncated.) [RT #37731]
3999. [func] "mkeys" and "nzf" files are now named after
their corresponding views, unless the view name
contains characters that would be incompatible
with use in a filename (i.e., slash, backslash,
or capital letters). If a view name does contain
these characters, the files will still be named
using a cryptographic hash of the view name.
Regardless of this, if a file using the old name
format is found to exist, it will continue to be
used. [RT #37704]
startup-notify-rate instead of serial-query-rate.
[RT #24454]
3955. [bug] Notify messages due to changes are no longer queued
behind startup notify messages. [RT #24454]
3936. [func] Added authoritative support for the EDNS Client
Subnet (ECS) option.
ACLs can now include "ecs" elements which specify
an address or network prefix; if an ECS option is
included in a DNS query, then the address encoded
in the option will be matched against "ecs" ACL
elements.
Also, if an ECS address is included in a query,
then it will be used instead of the client source
address when matching "geoip" ACL elements. This
behavior can be overridden with "geoip-use-ecs no;".
When "ecs" or "geoip" ACL elements are used to
select a view for a query, the response will include
an ECS option to indicate which client network the
answer is valid for.
(Thanks to Vincent Bernat.) [RT #36781]

Remove test for shortcut findnode()
The implementation was not included in this review branch, but the tests
erroneously made it through.
This functionality will be addressed in a different ticket (RT#35906).

RBT related updates
* Add various RBT unit tests
* Add some helper methods useful in unit testing RBT code
* General cleanup
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 PCKS#11 API implementation. [RT #35479]
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]
(which are similar to DNS Cookies by Donald Eastlake)
and are designed to help clients detect off path
spoofed responses and for servers to detect legitimate
clients.
SIT use a experimental EDNS option code (65001).
SIT can be enabled via --enable-developer or
--enable-sit. It is on by default in Windows.
RRL processing as been updated to know about SIT with
legitimate clients not being rate limited. [RT #35389]
3741. [func] "delve" (domain entity lookup and validation engine):
A new tool with dig-like semantics for performing DNS
lookups, with internal DNSSEC validation, using the
same resolver and validator logic as named. This
allows easy validation of DNSSEC data in environments
with untrustworthy resolvers, and assists with
troubleshooting of DNSSEC problems. (Note: not yet
available on win32.) [RT #32406]
information will be automatically updated if the
OS supports routing sockets. Use
"automatic-interface-scan no;" to disable.
Add "rndc scan" to trigger a scan. [RT #23027]
3705. [func] "configure --enable-native-pkcs11" enables BIND
to use the PKCS#11 API for all cryptographic
functions, so that it can drive a hardware service
module directly without the need to use a modified
OpenSSL as intermediary (so long as the HSM's vendor
provides a complete-enough implementation of the
PKCS#11 interface). This has been tested successfully
with the Thales nShield HSM and with SoftHSMv2 from
the OpenDNSSEC project. [RT #29031]
3700. [func] Allow access to subgroups of XML statistics via
special URLs http://<server>:<port>/xml/v3/server,
/zones, /net, /tasks, /mem, and /status. [RT #35115]
3699. [bug] Improvements to statistics channel XSL stylesheet:
the stylesheet can now be cached by the browser;
section headers are omitted from the stats display
when there is no data in those sections to be
displayed; counters are now right-justified for
easier readability. [RT #35117]
3535. [func] Add support for setting Differentiated Services Code
Point (DSCP) values in named. Most configuration
options which take a "port" option (e.g.,
listen-on, forwarders, also-notify, masters,
notify-source, etc) can now also take a "dscp"
option specifying a code point for use with
outgoing traffic, if supported by the underlying
OS. [RT #27596]
3524. [func] Added an alternate statistics channel in JSON format,
when the server is built with the json-c library:
http://[address]:[port]/json. [RT #32630]
3406. [bug] mem.c: Fix compilation errors when building with
ISC_MEM_TRACKLINES or ISC_MEMPOOL_NAMES disabled.
Also, ISC_MEM_DEBUG is no longer optional. [RT #31559]
