- 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]

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.

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
