4152. [func] Implement DNS COOKIE option. This replaces the
experimental SIT option of BIND 9.10. The following
named.conf directives are available: send-cookie,
cookie-secret, cookie-algorithm, nocookie-udp-size
and require-server-cookie. The following dig options
are available: +[no]cookie[=value] and +[no]badcookie.
[RT #39928]
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]
4156. [func] Added statistics counters to track the sizes
of incoming queries and outgoing responses in
histogram buckets, as specified in RSSAC002.
[RT #39049]
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]
4121. [bug] When updating a response-policy zone via AXFR,
summary data about other policy zones could fall
out of sync. Ultimately this could trigger an
assertion failure in rpz.c. [RT #39567]
4120. [bug] A bug in RPZ could cause the server to crash if
policy zones were updated while recursion was
pending for RPZ processing of an active query.
[RT #39415]
4108. [func] An additional NXDOMAIN redirect method (option
"nxdomain-redirect") has been added, allowing
redirection to a specified DNS namespace instead
of a single redirect zone. [RT #37989]
4080. [func] Completed change #4022, adding a "lock-file" option
to named.conf to override the default lock file,
in addition to the "named -X <filename>" command
line option. Setting the lock file to "none"
using either method disables the check completely.
[RT #37908]
4063. [bug] Asynchronous zone loads were not handled
correctly when the zone load was already in
progress; this could trigger a crash in zt.c.
[RT #37573]
4056. [bug] Expanded automatic testing of trust anchor
management and fixed several small bugs including
a memory leak and a possible loss of key state
information. [RT #38458]
4055. [func] "rndc managed-keys" can be used to check status
of trust anchors or to force keys to be refreshed,
Also, the managed keys data file has easier-to-read
comments. [RT #38458]
4053. [security] Revoking a managed trust anchor and supplying
an untrusted replacement could cause named
to crash with an assertion failure.
(CVE-2015-1349) [RT #38344]
4040. [func] Added server-side support for pipelined TCP
queries. TCP connections are no longer closed after
the first query received from a client. (The new
"keep-response-order" option allows clients to be
specified for which the old behavior will still be
used.) [RT #37821]
4034. [func] When added, negative trust anchors (NTA) are now
saved to files (viewname.nta), in order to
persist across restarts of the named server.
[RT #37087]
4030. [func] "rndc delzone" is now applicable to zones that were
configured in named.conf, as well as zones that
were added via "rndc addzone". (Note, however, that
if named.conf is not also modified, the deleted zone
will return when named is reloaded.) [RT #37887]
4029. [func] "rndc showzone" displays the current configuration
of a specified zone. [RT #37887]
Conflicts:
bin/tests/system/conf.sh.in
lib/dns/win32/libdns.def.in
lib/isc/win32/file.c
The merge also needed to update files in legacy and tcp system tests
(newly introduced in master after branch was created) to introduce use
of lockfile.
