3606. [func] "rndc flushtree -all" flushes matching
records in the ADB and bad cache as well as
the DNS cache. (Without the "-all" option,
flushtree will still only flush records from
the DNS cache.) [RT #33970]
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]

return noqname proof with +cd and dlv
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
Added API to create a set of UDP dispatches which can be shared
round-robin style when making upstream queries for authoritative
data; this should reduce lock contention in the query source
dispatch.
negative-cache records rather than using rrtype 0;
this will prevent problems when that rrtype is
used in actual DNS packets. [RT #24777]
3123. [security] Change #2912 exposed a latent flaw in
dns_rdataset_totext() that could cause named to
crash with an assertion failure. [RT #24777]
