silence 'may be used uninitialized' warning. [RT #45139] (cherry picked from commit d1554926d0f2acd8be83630c70f7e732c35cbd64)

4504. [security] Allow the maximum number of records in a zone to be specified. This provides a control for issues raised in CVE-2016-6170. [RT #42143] (cherry picked from commit 5f8412a4cb5ee14a0e8cddd4107854b40ee3291e)

4439. [bug] Address race conditions getting ownernames of nodes. [RT #43005] (cherry picked from commit c7e021e2e64a73f665a3a57b6eb06670d2a21603)

4401. [misc] Change LICENSE to MPL 2.0.

4081. [cleanup] Use dns_rdatalist_init consistently. [RT #38759]

4079. [func] Preserve the case of the ownername of records to the RRset level. [RT #37442]

4074. [cleanup] Cleaned up more warnings from gcc -Wshadow. [RT #38708]

4010. [cleanup] Clear the prefetchable state when initiating a prefetch. [RT #37399]

[master] suppress unnecessary db lookups in DLZ redirect zones 3876. [bug] Improve efficiency of DLZ redirect zones by suppressing unnecessary database lookups. [RT #35835]

[master] better DDNS in DLZ; mysqldyn 3821. [contrib] Added a new "mysqldyn" DLZ module with dynamic update and transaction support. Thanks to Marty Lee for the contribution. [RT #35656] 3820. [func] The DLZ API doesn't pass the database version to the lookup() function; this can cause DLZ modules that allow dynamic updates to mishandle prerequisite checks. This has been corrected by adding a 'dbversion' field to the dns_clientinfo_t structure. [RT #35656]

[master] DLZ modules: filesystem, ldap, wildcard 3523. [contrib] Ported filesystem and ldap DLZ drivers to dynamically-loadable modules, and added the "wildcard" module based on a contribution from Vadim Goncharov <vgoncharov@nic.ru>. [RT #23569]

[master] handle servfail at DLZ zone apex 3522. [bug] DLZ lookups could fail to return SERVFAIL when they ought to. [RT #32685]

[master] RPZ speedup (phase 2, multiple RPZ's) 3495. [func] Support multiple response-policy zones, while improving RPZ performance. [RT #32476]

update copyright notice

[master] DLZ fixes - handle malformed answers from DLZ better: - handle dlz_lookup errors better: when the first lookup of a name returns an unexpected failure code, we return it to the caller rather than continuing on to look up the wildcard. we now only continue processing if the return from the first lookup was either ISC_R_SUCCESS or ISC_R_NOTFOUND. - improved backward-compatibility for dlz_version: added a DLZ_DLOPEN_AGE value indicating how many versions back from the current DLZ_DLOPEN_VERSION named will support

3437. [bug] isc_buffer_init -> isc_buffer_constinit to initialise buffers with constant data. [RT #32064] Squashed commit of the following: commit 3433b96bf11f8c90ccbe412f01d02a6d8bbc2d33 Author: Mark Andrews <marka@isc.org> Date: Sat Dec 8 12:41:16 2012 +1100 isc_buffer_init -> isc_buffer_constinit commit c22dbcc1122a0a44f7b46068e0ccbc25353a57d5 Author: Mark Andrews <marka@isc.org> Date: Sat Dec 8 12:38:39 2012 +1100 isc_buffer_init -> isc_buffer_constinit commit 900820416c45c1887d0d22d7a010df60a903bd56 Author: Mark Andrews <marka@isc.org> Date: Sat Dec 8 12:24:19 2012 +1100 remove isc_buffer_reconstinit commit f815711c17b05f9961786a90b9bae902d3c01494 Author: Mark Andrews <marka@isc.org> Date: Wed Dec 5 15:42:57 2012 +1100 add isc_buffer_constinit

[master] pass client info to DLZ findzone method 3434. [bug] Pass client info to the DLZ findzone() entry point in addition to lookup(). This makes it possible for a database to answer differently whether it's authoritative for a name depending on the address of the client. [RT #31775]

[master] multiple-dlz/dlz-nxdomain 3432. [func] Multiple DLZ databases can now be configured. DLZ databases are searched in the order configured, unless set to "search no", in which case a zone can be configured to be retrieved from a particular DLZ database by using a "dlz <name>" option in the zone statement. DLZ databases can support type "master" and "redirect" zones. [RT #27597]

Merge statistics code (ATT SoW, rt24117) 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]

Re-created rt27597a for ongoing DLZ work

Revert accidental merge of unfinished DLZ work

checkpoint: multiple-DLZ functionality - multiple DLZ's can be specified, including multiple DLZ's using the same driver; e.g., two different back-ends both loaded by the dlopen driver - new "search" option can be specified in a DLZ indicating whether this DLZ database should be searched for unknown zones. The default is "yes". If "no", then the zone can only be found by named if it's registered in the zone table, which happens if the zone is configured for dynamic updates, or if "dlz <dlzname>" is specified in the zone statement. (The latter functionality is incomplete in this commit).

3251. [bug] Enforce a upper bound (65535 bytes) on the amount of memory dns_sdlz_putrr() can allocate per record to prevent run away memory consumption on ISC_R_NOSPACE. [RT #26956]

3164. [func] Enable DLZ modules to retrieve client information, so that responses can be changed depending on the source address of the query. [RT #25768]

3087. [bug] DDNS updates using SIG(0) with update-policy match type "external" could cause a crash. [RT #23735]

3069. [cleanup] Silence warnings messages from clang static analysis. [RT #20256]

3008. [func] Response policy zones (RPZ) support. [RT #21726]

removed unnecessary "done" log message from dns_sdlzcreate(); it used __FUNCTION__ which caused problems on some compilers.

2989. [func] Added support for writable DLZ zones. (Contributed 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. (Contributed by Andrew Tridgell of the Samba 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]
