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]
- check for mmap() in configure
- implement isc_file_mmap() and isc_file_munmap() to do
malloc()/read() and free() when run on systems that do not
support mmap().
This includes the following changes:
3326. [func] Added task list statistics: task model, worker
threads, quantum, tasks running, tasks ready.
[RT #27678]
3325. [func] Report cache statistics: memory use, number of
nodes, number of hash buckets, hit and miss counts.
[RT #27056]
3324. [test] Add better tests for ADB stats [RT #27057]
3323. [func] Report the number of buckets the resolver is using.
[RT #27020]
3322. [func] Monitor the number of active TCP and UDP dispatches.
[RT #27055]
3321. [func] Monitor the number of recursive fetches and the
number of open sockets, and report these values in
the statistics channel. [RT #27054]
3320. [func] Added support for monitoring of recursing client
count. [RT #27009]
3319. [func] Added support for monitoring of ADB entry count and
hash size. [RT #27057]
3316. [tuning] Improved locking performance when recursing.
[RT #28836]
- Use one lock per memory pool instead of associating
them all with a single 'pool_lock' in the dispatch manager.
- Reduce the critical sections for qid->lock in get_dispsocket(),
deref_portentry() and dns_dispatch_addresponse2().
- Added a memory pool for socket events in dns_dispatch_t.
- Add an isc_socketevent_t member in the resquery_t object, and use
it with isc_socket_sendto2() instead of using isc_socket_sendto()
- Tuned the memory pools in dispatch.c for better performance
under load
to 10. Allow setting this in named.conf using the new
'resolver-query-timeout' option, which specifies a max
time in seconds. 0 means 'default' and anything longer
than 30 will be silently set to 30. [RT #22852]
by Andrew Tridgell of the Samba project.) [RT #22629]
2988. [experimental] Added a "dlopen" DLZ driver, allowing the creation
of external DLZ drivers that can be loaded as
shared objects at runtime rather than linked with
named. Currently this is switched on via a
compile-time option, "configure --with-dlz-dlopen".
Note: the syntax for configuring DLZ zones
is likely to be refined in future releases.

project.) [RT #22629]
2987. [func] Improve ease of configuring TKEY/GSS updates by
adding a "tkey-gssapi-keytab" option. If set,
updates will be allowed with any key matching
a principal in the specified keytab file.
"tkey-gssapi-credential" is no longer required
and is expected to be deprecated. (Contributed
by Andrew Tridgell of the Samba project.)
[RT #22629]
memory conditions. Without this fix a DNS cache DB or
ADB could incorrectly stay in an over memory state,
effectively refusing further caching, which
subsequently made a BIND 9 caching server unworkable.
This fix prevents this problem from happening by
polling the state of the memory context, rather than
making a copy of the state, which appeared to cause
a race. This is a "workaround" in that it doesn't
solve the possible race per se, but several experiments
proved this change solves the symptom. Also, the
polling overhead hasn't been reported to be an issue.
This bug should only affect a caching server that
specifies a finite max-cache-size. It's also quite
likely that the bug happens only when enabling threads,
but it's not confirmed yet. [RT #21818]
digest length were used incorrectly, leading to
interoperability problems with other DNS
implementations. This has been corrected.
(Note: If an oversize key is in use, and
compatibility is needed with an older release of
BIND, the new tool "isc-hmac-fixup" can convert
the key secret to a form that will work with all
versions.) [RT #20751]
