For example, if you have three WWW servers with network addresses of 10.0.0.1, 10.0.0.2 and 10.0.0.3, a set of records such as the following means that clients will connect to each machine one third of the time:

The following command will generate a 128-bit (16 byte) HMAC-SHA256 key as described above. Longer keys are better, but shorter keys are easier to read. Note that the maximum key length is the digest length, here 256 bits.

dnssec-keygen -a hmac-sha256 -b 128 -n HOST host1-host2.

-

The key is in the file Khost1-host2.+163+00000.private. Nothing directly uses this file, but the base-64 encoded string following "Key:" can be extracted from the file and used as a shared secret:

-

+
 key host1-host2. {
   algorithm hmac-sha256;
   secret "La/E5CjG9O+os1jq0a2jdA==";
 };
 
-

+ +

The secret is the one generated above. Since this is a secret, it is recommended that either named.conf be non-world readable, or the key directive be added to a non-world readable file that is included by named.conf.

-

+

At this point, the key is recognized. This means that if the server receives a message signed by this key, it can verify the signature. If the signature is successfully verified, the response is signed by the same key.

Since keys are shared between two hosts only, the server must be told when keys are to be used. The following is added to the named.conf file for host1, if the IP address of host2 is 10.1.2.3:

+
 server 10.1.2.3 {
   keys { host1-host2. ;};
 };
 
-

+ +

Multiple keys may be present, but only the first is used. This directive does not contain any secrets, so it may be in a world-readable file.

-

+

If host1 sends a message that is a request to that address, the message will be signed with the specified key. host1 will expect any responses to signed messages to be signed with the same key.

A similar statement must be present in host2's configuration file (with host1's address) for host2 to sign request messages to host1.

Address match lists are primarily used to determine access control for various server operations. They are also used in - the listen-on and sortlist + the listen-on and sortlist statements. The elements which constitute an address match list can be any of the following:

    + +

    Elements can be negated with a leading exclamation mark (`!'), and the match list names "any", "none", "localhost", and "localnets" are predefined. More information on those names can be found in the description of the acl statement.

    -

    + +

    The addition of the key clause made the name of this syntactic element something of a misnomer, since security keys can be used to validate access without regard to a host or network address. Nonetheless, the term "address match list" is still used throughout the documentation.

    -

    + +

    When a given IP address or prefix is compared to an address match list, the comparison takes place in approximately O(1) time. However, key comparisons require that the list of keys be traversed until a matching key is found, and therefore may be somewhat slower.

BIND 9 provides the ability to filter out DNS responses from external DNS servers containing certain types of data in the answer section.

It can also reject CNAME or DNAME records if the "alias" name (i.e., the CNAME alias or the substituted query name due to DNAME) matches the given namelist of the - deny-answer-aliases option, where + deny-answer-aliases option, where "match" means the alias name is a subdomain of one of the name_list elements. If the optional namelist is specified - with except-from, records whose query name + with except-from, records whose query name matches the list will be accepted regardless of the filter setting. Likewise, if the alias name is a subdomain of the - corresponding zone, the deny-answer-aliases + corresponding zone, the deny-answer-aliases filter will not apply; for example, even if "example.com" is specified for - deny-answer-aliases, + deny-answer-aliases,

In the address_match_list of the - deny-answer-addresses option, only + deny-answer-addresses option, only ip_addr and ip_prefix are meaningful; any key_id will be silently ignored.

If a response message is rejected due to the filtering, the entire message is discarded without being cached, and a SERVFAIL error will be returned to the client.

Access Control Lists

-

Access Control Lists (ACLs) are address match lists that you can set up and nickname for future use in - allow-notify, allow-query, - allow-query-on, allow-recursion, - blackhole, allow-transfer, - match-clients, etc. + allow-notify, allow-query, + allow-query-on, allow-recursion, + blackhole, allow-transfer, + match-clients, etc.

-

+

Using ACLs allows you to have finer control over who can access your name server, without cluttering up your config files with huge lists of IP addresses.

-

+

It is a good idea to use ACLs, and to control access to your server. Limiting access to your server by outside parties can help prevent spoofing and denial of service (DoS) attacks against your server.

-

+

ACLs match clients on the basis of up to three characteristics: 1) The client's IP address; 2) the TSIG or SIG(0) key that was used to sign the request, if any; and 3) an address prefix encoded in an EDNS Client Subnet option, if any.

-

+

Here is an example of ACLs based on client addresses:

This allows authoritative queries for "example.com" from any address, but recursive queries only from the networks specified in "our-nets", and no queries at all from the networks specified in "bogusnets".

-

In addition to network addresses and prefixes, which are matched against the source address of the DNS request, ACLs may include key elements, which specify the @@ -128,34 +131,34 @@ zone "example.com" { if that prefix matches an EDNS client subnet option included in the request.

-

+

The EDNS Client Subnet (ECS) option is used by a recursive resolver to inform an authoritative name server of the network address block from which the original query was received, enabling authoritative servers to give different answers to the same resolver for different resolver clients. An ACL containing an element of the form - ecs prefix + ecs prefix will match if a request arrives in containing an ECS option encoding an address within that prefix. If the request has no ECS option, then "ecs" elements are simply ignored. Addresses in ACLs that are not prefixed with "ecs" are matched only against the source address.

-

+

When BIND 9 is built with GeoIP support, ACLs can also be used for geographic access restrictions. This is done by specifying an ACL element of the form: - geoip [db database] field value + geoip [db database] field value

-

+

The field indicates which field to search for a match. Available fields are "country", "region", "city", "continent", "postal" (postal code), "metro" (metro code), "area" (area code), "tz" (timezone), "isp", "org", "asnum", "domain" and "netspeed".

By default, if a DNS query includes an EDNS Client Subnet (ECS) option which encodes a non-zero address prefix, then GeoIP ACLs will be matched against that address prefix. Otherwise, they are matched against the source address of the query. To prevent GeoIP ACLs from matching against ECS options, set - the geoip-use-ecs to no. + the geoip-use-ecs to no.

+Security Fixes

+ +
    +
  • +

    + An incorrect boundary check in the OPENPGPKEY rdatatype + could trigger an assertion failure. This flaw is disclosed + in CVE-2015-5986. [RT #40286] +

    +
  • +
  • +

    + A buffer accounting error could trigger an assertion failure + when parsing certain malformed DNSSEC keys. +

    +

    + This flaw was discovered by Hanno Böck of the Fuzzing + Project, and is disclosed in CVE-2015-5722. [RT #40212] +

    +
  • +
  • +

    + A specially crafted query could trigger an assertion failure + in message.c. +

    +

    + This flaw was discovered by Jonathan Foote, and is disclosed + in CVE-2015-5477. [RT #40046] +

    +
  • +
  • +

    + On servers configured to perform DNSSEC validation, an + assertion failure could be triggered on answers from + a specially configured server. +

    +

    + This flaw was discovered by Breno Silveira Soares, and is + disclosed in CVE-2015-4620. [RT #39795] +

    +
  • +
  • +

    + On servers configured to perform DNSSEC validation using + managed trust anchors (i.e., keys configured explicitly + via managed-keys, or implicitly + via dnssec-validation auto; or + dnssec-lookaside auto;), revoking + a trust anchor and sending a new untrusted replacement + could cause named to crash with an + assertion failure. This could occur in the event of a + botched key rollover, or potentially as a result of a + deliberate attack if the attacker was in position to + monitor the victim's DNS traffic. +

    +

    + This flaw was discovered by Jan-Piet Mens, and is + disclosed in CVE-2015-1349. [RT #38344] +

    +
  • +
  • +

    + A flaw in delegation handling could be exploited to put + named into an infinite loop, in which + each lookup of a name server triggered additional lookups + of more name servers. This has been addressed by placing + limits on the number of levels of recursion + named will allow (default 7), and + on the number of queries that it will send before + terminating a recursive query (default 50). +

    +

    + The recursion depth limit is configured via the + max-recursion-depth option, and the query limit + via the max-recursion-queries option. +

    +

    + The flaw was discovered by Florian Maury of ANSSI, and is + disclosed in CVE-2014-8500. [RT #37580] +

    +
  • +
  • +

    + Two separate problems were identified in BIND's GeoIP code that + could lead to an assertion failure. One was triggered by use of + both IPv4 and IPv6 address families, the other by referencing + a GeoIP database in named.conf which was + not installed. Both are covered by CVE-2014-8680. [RT #37672] + [RT #37679] +

    +

    + A less serious security flaw was also found in GeoIP: changes + to the geoip-directory option in + named.conf were ignored when running + rndc reconfig. In theory, this could allow + named to allow access to unintended clients. +

    +
  • +
+
+
+

+New Features

+ +
    +
  • +

    + Added support for DynDB, a new interface for loading zone data + from an external database, developed by Red Hat for the FreeIPA + project. (Thanks in particular to Adam Tkac and Petr + Spacek of Red Hat for the contribution.) +

    +

    + Unlike the existing DLZ and SDB interfaces, which provide a + limited subset of database functionality within BIND — + translating DNS queries into real-time database lookups with + relatively poor performance and with no ability to handle + DNSSEC-signed data — DynDB is able to fully implement + and extend the database API used natively by BIND. +

    +

    + A DynDB module could pre-load data from an external data + source, then serve it with the same performance and + functionality as conventional BIND zones, and with the + ability to take advantage of database features not + available in BIND, such as multi-master replication. +

    +
  • +
  • +

    + New quotas have been added to limit the queries that are + sent by recursive resolvers to authoritative servers + experiencing denial-of-service attacks. When configured, + these options can both reduce the harm done to authoritative + servers and also avoid the resource exhaustion that can be + experienced by recursives when they are being used as a + vehicle for such an 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.) +

      +
    • +
    +

    + Statistics counters have also been added to track the number + of queries affected by these quotas. +

    +
  • +
  • +

    + Added support for dnstap, a fast, + flexible method for capturing and logging DNS traffic, + developed by Robert Edmonds at Farsight Security, Inc., + whose assistance is gratefully acknowledged. +

    +

    + To enable dnstap at compile time, + the fstrm and protobuf-c + libraries must be available, and BIND must be configured with + --enable-dnstap. +

    +

    + A new utility dnstap-read has been added + to allow dnstap data to be presented in + a human-readable format. +

    +

    + For more information on dnstap, see + http://dnstap.info. +

    +
  • +
  • +

    + New statistics counters have been added to track traffic + sizes, as specified in RSSAC002. Query and response + message sizes are broken up into ranges of histogram buckets: + TCP and UDP queries of size 0-15, 16-31, ..., 272-288, and 288+, + and TCP and UDP responses of size 0-15, 16-31, ..., 4080-4095, + and 4096+. These values can be accessed via the XML and JSON + statistics channels at, for example, + http://localhost:8888/xml/v3/traffic + or + http://localhost:8888/json/v1/traffic. +

    +
  • +
  • +

    + The serial number of a dynamically updatable zone can + now be set using + rndc signing -serial number zonename. + This is particularly useful with inline-signing + zones that have been reset. Setting the serial number to a value + larger than that on the slaves will trigger an AXFR-style + transfer. +

    +
  • +
  • +

    + When answering recursive queries, SERVFAIL responses can now be + cached by the server for a limited time; subsequent queries for + the same query name and type will return another SERVFAIL until + the cache times out. This reduces the frequency of retries + when a query is persistently failing, which can be a burden + on recursive serviers. The SERVFAIL cache timeout is controlled + by servfail-ttl, which defaults to 10 seconds + and has an upper limit of 30. +

    +
  • +
  • +

    + The new rndc nta command can now be used to + set a "negative trust anchor" (NTA), disabling DNSSEC validation for + a specific domain; this can be used when responses from a domain + are known to be failing validation due to administrative error + rather than because of a spoofing attack. NTAs are strictly + temporary; by default they expire after one hour, but can be + configured to last up to one week. The default NTA lifetime + can be changed by setting the nta-lifetime in + named.conf. When added, NTAs are stored in a + file (viewname.nta) + in order to persist across restarts of the named server. +

    +
  • +
  • +

    + The EDNS Client Subnet (ECS) option is now supported for + authoritative servers; if a query contains an ECS option then + ACLs containing geoip or ecs + elements can match against the the address encoded in the option. + This can be used to select a view for a query, so that different + answers can be provided depending on the client network. +

    +
  • +
  • +

    + The EDNS EXPIRE option has been implemented on the client + side, allowing a slave server to set the expiration timer + correctly when transferring zone data from another slave + server. +

    +
  • +
  • +

    + A new masterfile-style zone option controls + the formatting of text zone files: When set to + full, the zone file will dumped in + single-line-per-record format. +

    +
  • +
  • +

    + dig +ednsopt can now be used to set + arbitrary EDNS options in DNS requests. +

    +
  • +
  • +

    + dig +ednsflags can now be used to set + yet-to-be-defined EDNS flags in DNS requests. +

    +
  • +
  • +

    + dig +[no]ednsnegotiation can now be used enable / + disable EDNS version negotiation. +

    +
  • +
  • +

    + dig +header-only can now be used to send + queries without a question section. +

    +
  • +
  • +

    + dig +ttlunits causes dig + to print TTL values with time-unit suffixes: w, d, h, m, s for + weeks, days, hours, minutes, and seconds. +

    +
  • +
  • +

    + dig +zflag can be used to set the last + unassigned DNS header flag bit. This bit in normally zero. +

    +
  • +
  • +

    + dig +dscp=value + can now be used to set the DSCP code point in outgoing query + packets. +

    +
  • +
  • +

    + serial-update-method can now be set to + date. On update, the serial number will + be set to the current date in YYYYMMDDNN format. +

    +
  • +
  • +

    + dnssec-signzone -N date also sets the serial + number to YYYYMMDDNN. +

    +
  • +
  • +

    + named -L filename + causes named to send log messages to the specified file by + default instead of to the system log. +

    +
  • +
  • +

    + The rate limiter configured by the + serial-query-rate option no longer covers + NOTIFY messages; those are now separately controlled by + notify-rate and + startup-notify-rate (the latter of which + controls the rate of NOTIFY messages sent when the server + is first started up or reconfigured). +

    +
  • +
  • +

    + The default number of tasks and client objects available + for serving lightweight resolver queries have been increased, + and are now configurable via the new lwres-tasks + and lwres-clients options in + named.conf. [RT #35857] +

    +
  • +
  • +

    + Log output to files can now be buffered by specifying + buffered yes; when creating a channel. +

    +
  • +
  • +

    + delv +tcp will exclusively use TCP when + sending queries. +

    +
  • +
  • +

    + named will now check to see whether + other name server processes are running before starting up. + This is implemented in two ways: 1) by refusing to start + if the configured network interfaces all return "address + in use", and 2) by attempting to acquire a lock on a file + specified by the lock-file option or + the -X command line option. The + default lock file is + /var/run/named/named.lock. + Specifying none will disable the lock + file check. +

    +
  • +
  • +

    + rndc delzone can now be applied to zones + which were configured in named.conf; + it is no longer restricted to zones which were added by + rndc addzone. (Note, however, that + this does not edit named.conf; the zone + must be removed from the configuration or it will return + when named is restarted or reloaded.) +

    +
  • +
  • +

    + rndc modzone can be used to reconfigure + a zone, using similar syntax to rndc addzone. +

    +
  • +
  • +

    + rndc showzone displays the current + configuration for a specified zone. +

    +
  • +
  • +

    + Added server-side support for pipelined TCP queries. Clients + may continue sending queries via TCP while previous queries are + processed in parallel. Responses are sent when they are + ready, not necessarily in the order in which the queries were + received. +

    +

    + To revert to the former behavior for a particular + client address or range of addresses, specify the address prefix + in the "keep-response-order" option. To revert to the former + behavior for all clients, use "keep-response-order { any; };". +

    +
  • +
  • +

    + The new mdig command is a version of + dig that sends multiple pipelined + queries and then waits for responses, instead of sending one + query and waiting the response before sending the next. [RT #38261] +

    +
  • +
  • +

    + To enable better monitoring and troubleshooting of RFC 5011 + trust anchor management, the new 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 now has + easier-to-read comments. [RT #38458] +

    +
  • +
  • +

    + An --enable-querytrace configure switch is + now available to enable very verbose query tracelogging. This + option can only be set at compile time. This option has a + negative performance impact and should be used only for + debugging. [RT #37520] +

    +
  • +
  • +

    + A new tcp-only option can be specified + in server statements to force + named to connect to the specified + server via TCP. [RT #37800] +

    +
  • +
  • +

    + The nxdomain-redirect option specifies + a DNS namespace to use for NXDOMAIN redirection. When a + recursive lookup returns NXDOMAIN, a second lookup is + initiated with the specified name appended to the query + name. This allows NXDOMAIN redirection data to be supplied + by multiple zones configured on the server or by recursive + queries to other servers. (The older method, using + a single type redirect zone, has + better average performance but is less flexible.) [RT #37989] +

    +
  • +
  • +

    + The following types have been implemented: CSYNC, NINFO, RKEY, + SINK, TA, TALINK. +

    +
  • +
+
+
+

+Feature Changes

+ +
    +
  • +

    + ACLs containing geoip asnum elements were + not correctly matched unless the full organization name was + specified in the ACL (as in + geoip asnum "AS1234 Example, Inc.";). + They can now match against the AS number alone (as in + geoip asnum "AS1234";). +

    +
  • +
  • +

    + When using native PKCS#11 cryptography (i.e., + configure --enable-native-pkcs11) HSM PINs + of up to 256 characters can now be used. +

    +
  • +
  • +

    + NXDOMAIN responses to queries of type DS are now cached separately + from those for other types. This helps when using "grafted" zones + of type forward, for which the parent zone does not contain a + delegation, such as local top-level domains. Previously a query + of type DS for such a zone could cause the zone apex to be cached + as NXDOMAIN, blocking all subsequent queries. (Note: This + change is only helpful when DNSSEC validation is not enabled. + "Grafted" zones without a delegation in the parent are not a + recommended configuration.) +

    +
  • +
  • +

    + Update forwarding performance has been improved by allowing + a single TCP connection to be shared between multiple updates. +

    +
  • +
  • +

    + By default, nsupdate will now check + the correctness of hostnames when adding records of type + A, AAAA, MX, SOA, NS, SRV or PTR. This behavior can be + disabled with check-names no. +

    +
  • +
  • +

    + Added support for OPENPGPKEY type. +

    +
  • +
  • +

    + The names of the files used to store managed keys and added + zones for each view are no longer based on the SHA256 hash + of the view name, except when this is necessary because the + view name contains characters that would be incompatible with use + as a file name. For views whose names do not contain forward + slashes ('/'), backslashes ('\'), or capital letters - which + could potentially cause namespace collision problems on + case-insensitive filesystems - files will now be named + after the view (for example, internal.mkeys + or external.nzf). However, to ensure + consistent behavior when upgrading, if a file using the old + name format is found to exist, it will continue to be used. +

    +
  • +
  • +

    + "rndc" can now return text output of arbitrary size to + the caller. (Prior to this, certain commands such as + "rndc tsig-list" and "rndc zonestatus" could return + truncated output.) +

    +
  • +
  • +

    + Errors reported when running rndc addzone + (e.g., when a zone file cannot be loaded) have been clarified + to make it easier to diagnose problems. +

    +
  • +
  • +

    + When encountering an authoritative name server whose name is + an alias pointing to another name, the resolver treats + this as an error and skips to the next server. Previously + this happened silently; now the error will be logged to + the newly-created "cname" log category. +

    +
  • +
  • +

    + If named is not configured to validate the answer then + allow fallback to plain DNS on timeout even when we know + the server supports EDNS. This will allow the server to + potentially resolve signed queries when TCP is being + blocked. +

    +
  • +
  • +

    + Large inline-signing changes should be less disruptive. + Signature generation is now done incrementally; the number + of signatures to be generated in each quantum is controlled + by "sig-signing-signatures number;". + [RT #37927] +

    +
  • +
  • +

    + The experimental SIT option (code point 65001) of BIND + 9.10.0 through BIND 9.10.2 has been replaced with the COOKIE + option (code point 10). It is no longer experimental, and + is sent by default, by both named and + dig. +

    +

    + The SIT-related named.conf options have been marked as + obsolete, and are otherwise ignored. +

    +
  • +
  • +

    + When dig receives a truncated (TC=1) + response or a BADCOOKIE response code from a server, it + will automatically retry the query using the server COOKIE + that was returned by the server in its initial response. + [RT #39047] +

    +
  • +
  • +

    + A alternative NXDOMAIN redirect method (nxdomain-redirect) + which allows the redirect information to be looked up from + a namespace on the Internet rather than requiring a zone + to be configured on the server is now available. +

    +
  • +
  • +

    + Retrieving the local port range from net.ipv4.ip_local_port_range + on Linux is now supported. +

    +
  • +
  • +

    + Within the response-policy option, it is now + possible to configure RPZ rewrite logging on a per-zone basis + using the log clause. +

    +
  • +
  • +

    + The default preferred glue is now the address type of the + transport the query was received over. +

    +
  • +
  • +

    + On machines with 2 or more processors (CPU), the default value + for the number of UDP listeners has been changed to the number + of detected processors minus one. +

    +
  • +
+
+
+

+Porting Changes

+ +
  • +

    + The Microsoft Windows install tool + BINDInstall.exe which requires a + non-free version of Visual Studio to be built, now uses two + files (lists of flags and files) created by the Configure + perl script with all the needed information which were + previously compiled in the binary. Read + win32utils/build.txt for more details. + [RT #38915] +

    +
+
+
+

+Bug Fixes

+ +
    +
  • +

    + dig, host and + nslookup aborted when encountering + a name which, after appending search list elements, + exceeded 255 bytes. Such names are now skipped, but + processing of other names will continue. [RT #36892] +

    +
  • +
  • +

    + The error message generated when + named-checkzone or + named-checkconf -z encounters a + $TTL directive without a value has + been clarified. [RT #37138] +

    +
  • +
  • +

    + Semicolon characters (;) included in TXT records were + incorrectly escaped with a backslash when the record was + displayed as text. This is actually only necessary when there + are no quotation marks. [RT #37159] +

    +
  • +
  • +

    + When files opened for writing by named, + such as zone journal files, were referenced more than once + in named.conf, it could lead to file + corruption as multiple threads wrote to the same file. This + is now detected when loading named.conf + and reported as an error. [RT #37172] +

    +
  • +
  • +

    + When checking for updates to trust anchors listed in + managed-keys, named + now revalidates keys based on the current set of + active trust anchors, without relying on any cached + record of previous validation. [RT #37506] +

    +
  • +
  • +

    + Large-system tuning + (configure --with-tuning=large) caused + problems on some platforms by setting a socket receive + buffer size that was too large. This is now detected and + corrected at run time. [RT #37187] +

    +
  • +
  • +

    + When NXDOMAIN redirection is in use, queries for a name + that is present in the redirection zone but a type that + is not present will now return NOERROR instead of NXDOMAIN. +

    +
  • +
  • +

    + Due to an inadvertent removal of code in the previous + release, when named encountered an + authoritative name server which dropped all EDNS queries, + it did not always try plain DNS. This has been corrected. + [RT #37965] +

    +
  • +
  • +

    + A regression caused nsupdate to use the default recursive servers + rather than the SOA MNAME server when sending the UPDATE. +

    +
  • +
  • +

    + Adjusted max-recursion-queries to accommodate the smaller + initial packet sizes used in BIND 9.10 and higher when + contacting authoritative servers for the first time. +

    +
  • +
  • +

    + Built-in "empty" zones did not correctly inherit the + "allow-transfer" ACL from the options or view. [RT #38310] +

    +
  • +
  • +

    + Two leaks were fixed that could cause named + processes to grow to very large sizes. [RT #38454] +

    +
  • +
  • +

    + Fixed some bugs in RFC 5011 trust anchor management, + including a memory leak and a possible loss of state + information. [RT #38458] +

    +
  • +
  • +

    + 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] +

    +
  • +
  • +

    + A race during shutdown or reconfiguration could + cause an assertion failure in mem.c. [RT #38979] +

    +
  • +
  • +

    + Some answer formatting options didn't work correctly with + dig +short. [RT #39291] +

    +
  • +
  • +

    + Several bugs have been fixed in the RPZ implementation: +

    +
      +
    • +

      + Policy zones that did not specifically require recursion + could be treated as if they did; consequently, setting + qname-wait-recurse no; was + sometimes ineffective. This has been corrected. + In most configurations, behavioral changes due to this + fix will not be noticeable. [RT #39229] +

      +
    • +
    • +

      + The server could crash if policy zones were updated (e.g. + via rndc reload or an incoming zone + transfer) while RPZ processing was still ongoing for an + active query. [RT #39415] +

      +
    • +
    • +

      + On servers with one or more policy zones configured as + slaves, if a policy zone updated during regular operation + (rather than at startup) using a full zone reload, such as + via AXFR, a bug could allow the RPZ summary data to fall out + of sync, potentially leading to an assertion failure in + rpz.c when further incremental updates were made to the + zone, such as via IXFR. [RT #39567] +

      +
    • +
    • +

      + The server could match a shorter prefix than what was + available in CLIENT-IP policy triggers, and so, an + unexpected action could be taken. This has been + corrected. [RT #39481] +

      +
    • +
    • +

      + The server could crash if a reload of an RPZ zone was + initiated while another reload of the same zone was + already in progress. [RT #39649] +

      +

This version of BIND 9 "exports" its internal libraries so that they can be used by third-party applications more easily (we call them "export" libraries in this document). In addition to all major DNS-related APIs BIND 9 is currently using, the export libraries provide the following features:

      The newly created "DNS client" module. This is a higher level API that provides an interface to name resolution, single DNS transaction with a particular server, and dynamic update. Regarding name resolution, it supports advanced features such as DNSSEC validation and caching. This module - supports both synchronous and asynchronous mode.

      The new "IRS" (Information Retrieval System) library. It provides an interface to parse the traditional resolv.conf file and more advanced, DNS-specific configuration file for the rest of this package (see the description for the - dns.conf file below).

      +
    • +
    • +

      As part of the IRS library, newly implemented standard address-name mapping functions, getaddrinfo() and getnameinfo(), are provided. They use the DNSSEC-aware validating resolver backend, and could use other advanced features of the BIND 9 libraries such as caching. The getaddrinfo() function resolves both A and AAAA RRs - concurrently (when the address family is unspecified).

+ +

GNU make is required to build the export libraries (other part of BIND 9 can still be built with other types of make). In the reminder of this document, "make" means GNU make. Note that in some platforms you may need to invoke a different command name than "make" (e.g. "gmake") to indicate it's GNU make.

-Compilation

-
+Compilation
+ +
 $ ./configure --enable-exportlib [other flags]
 $ make
 
-

+

This will create (in addition to usual BIND 9 programs) and a separate set of libraries under the lib/export directory. For example, lib/export/dns/libdns.a is the archive file of the export version of the BIND 9 DNS library. Sample application programs using the libraries will also be built under the lib/export/samples directory (see below).

-
-
+
+

-Installation

-
+Installation
+ +
 $ cd lib/export
 $ make install

+

This will install library object files under the directory specified by the --with-export-libdir configure option (default: EPREFIX/lib/bind9), and header files under the directory specified by the --with-export-includedir configure option (default: PREFIX/include/bind9). Root privilege is normally required. - "make install" at the top directory will do the + "make install" at the top directory will do the same.

    To build the SHA-256 DS RR from the Kexample.com.+003+26160 keyfile name, the following command would be issued:

    If no algorithm is specified, then RSASHA1 will be used by default, unless the -3 option is specified, in which case NSEC3RSASHA1 will be used instead. (If -3 is used and an algorithm is specified, that algorithm will be checked for compatibility with NSEC3.)

    DESCRIPTION

    + +

    dnssec-keygen generates keys for DNSSEC (Secure DNS), as defined in RFC 2535 and RFC 4034. It can also generate keys for use with TSIG (Transaction Signatures) as defined in RFC 2845, or TKEY (Transaction Key) as defined in RFC 2930.

    DESCRIPTION

    + + +

    lwresd is the daemon providing name lookup services to clients that use the BIND 9 lightweight resolver library. It is essentially a stripped-down, caching-only name server that answers queries using the BIND 9 lightweight resolver protocol rather than the DNS protocol.

This - means that lwresd can only be used by + means that lwresd can only be used by processes running on the local machine. By default, UDP port number 921 is used for lightweight resolver requests and responses.

    Incoming lightweight resolver requests are decoded by the server which then resolves them using the DNS protocol. When - the DNS lookup completes, lwresd encodes + the DNS lookup completes, lwresd encodes the answers in the lightweight resolver format and returns them to the client that made the request.

    +

    If /etc/resolv.conf contains any - nameserver entries, lwresd + nameserver entries, lwresd sends recursive DNS queries to those servers. This is similar to the use of forwarders in a caching name server. If no nameserver entries are present, or if - forwarding fails, lwresd resolves the + forwarding fails, lwresd resolves the queries autonomously starting at the root name servers, using a built-in list of root server hints.

    DESCRIPTION

    + +

    named-rrchecker read a individual DNS resource record from standard input and checks if it is syntactically correct.

    +

    The -h prints out the help menu.

    -

    +

    The -o origin option specifies a origin to be used when interpreting the record.

    -

    +

    The -p prints out the resulting record in canonical form. If there is no canonical form defined then the record will be printed in unknown record format.

    -

    +

    The -u prints out the resulting record in unknown record form.

    -

    +

    The -C, -T and -P print out the known class, standard type and private type mnemonics respectively.

    DESCRIPTION

    nsupdate is used to submit Dynamic DNS Update requests as defined in RFC 2136 to a name server. This allows resource records to be added or removed from a zone @@ -60,114 +92,134 @@ one resource record.

    Zones that are under dynamic control via - nsupdate + nsupdate or a DHCP server should not be edited by hand. Manual edits could conflict with dynamic updates and cause data to be lost.

    -

    +

    The resource records that are dynamically added or removed with - nsupdate + nsupdate have to be in the same zone. Requests are sent to the zone's master server. This is identified by the MNAME field of the zone's SOA record.

    +

    Transaction signatures can be used to authenticate the Dynamic DNS updates. These use the TSIG resource record type described in RFC 2845 or the SIG(0) record described in RFC 2535 and RFC 2931 or GSS-TSIG as described in RFC 3645.

You can use ddns-confgen to generate suitable configuration fragments. - nsupdate + nsupdate uses the -y or -k options to provide the TSIG shared secret. These options are mutually exclusive.

    +

    SIG(0) uses public key cryptography. To use a SIG(0) key, the public key must be stored in a KEY record in a zone served by the name server.

    +

    GSS-TSIG uses Kerberos credentials. Standard GSS-TSIG mode is switched on with the -g flag. A non-standards-compliant variant of GSS-TSIG used by Windows 2000 can be switched on with the -o flag.

    +Release Notes for BIND Version 9.11.0pre-alpha

    + +
    +

    +Introduction

    + +

    + This document summarizes changes since the last production release + of BIND on the corresponding major release branch. +

    +
    +
    +

    +Download

    + +

    + The latest versions of BIND 9 software can always be found at + http://www.isc.org/downloads/. + There you will find additional information about each release, + source code, and pre-compiled versions for Microsoft Windows + operating systems. +

    +
    +
    +

    +Security Fixes

    + +
      +
    • +

      + An incorrect boundary check in the OPENPGPKEY rdatatype + could trigger an assertion failure. This flaw is disclosed + in CVE-2015-5986. [RT #40286] +

      +
    • +
    • +

      + A buffer accounting error could trigger an assertion failure + when parsing certain malformed DNSSEC keys. +

      +

      + This flaw was discovered by Hanno Böck of the Fuzzing + Project, and is disclosed in CVE-2015-5722. [RT #40212] +

      +
    • +
    • +

      + A specially crafted query could trigger an assertion failure + in message.c. +

      +

      + This flaw was discovered by Jonathan Foote, and is disclosed + in CVE-2015-5477. [RT #40046] +

      +
    • +
    • +

      + On servers configured to perform DNSSEC validation, an + assertion failure could be triggered on answers from + a specially configured server. +

      +

      + This flaw was discovered by Breno Silveira Soares, and is + disclosed in CVE-2015-4620. [RT #39795] +

      +
    • +
    • +

      + On servers configured to perform DNSSEC validation using + managed trust anchors (i.e., keys configured explicitly + via managed-keys, or implicitly + via dnssec-validation auto; or + dnssec-lookaside auto;), revoking + a trust anchor and sending a new untrusted replacement + could cause named to crash with an + assertion failure. This could occur in the event of a + botched key rollover, or potentially as a result of a + deliberate attack if the attacker was in position to + monitor the victim's DNS traffic. +

      +

      + This flaw was discovered by Jan-Piet Mens, and is + disclosed in CVE-2015-1349. [RT #38344] +

      +
    • +
    • +

      + A flaw in delegation handling could be exploited to put + named into an infinite loop, in which + each lookup of a name server triggered additional lookups + of more name servers. This has been addressed by placing + limits on the number of levels of recursion + named will allow (default 7), and + on the number of queries that it will send before + terminating a recursive query (default 50). +

      +

      + The recursion depth limit is configured via the + max-recursion-depth option, and the query limit + via the max-recursion-queries option. +

      +

      + The flaw was discovered by Florian Maury of ANSSI, and is + disclosed in CVE-2014-8500. [RT #37580] +

      +
    • +
    • +

      + Two separate problems were identified in BIND's GeoIP code that + could lead to an assertion failure. One was triggered by use of + both IPv4 and IPv6 address families, the other by referencing + a GeoIP database in named.conf which was + not installed. Both are covered by CVE-2014-8680. [RT #37672] + [RT #37679] +

      +

      + A less serious security flaw was also found in GeoIP: changes + to the geoip-directory option in + named.conf were ignored when running + rndc reconfig. In theory, this could allow + named to allow access to unintended clients. +

      +
    • +
    +
    +
    +

    +New Features

    + +
      +
    • +

      + Added support for DynDB, a new interface for loading zone data + from an external database, developed by Red Hat for the FreeIPA + project. (Thanks in particular to Adam Tkac and Petr + Spacek of Red Hat for the contribution.) +

      +

      + Unlike the existing DLZ and SDB interfaces, which provide a + limited subset of database functionality within BIND — + translating DNS queries into real-time database lookups with + relatively poor performance and with no ability to handle + DNSSEC-signed data — DynDB is able to fully implement + and extend the database API used natively by BIND. +

      +

      + A DynDB module could pre-load data from an external data + source, then serve it with the same performance and + functionality as conventional BIND zones, and with the + ability to take advantage of database features not + available in BIND, such as multi-master replication. +

      +
    • +
    • +

      + New quotas have been added to limit the queries that are + sent by recursive resolvers to authoritative servers + experiencing denial-of-service attacks. When configured, + these options can both reduce the harm done to authoritative + servers and also avoid the resource exhaustion that can be + experienced by recursives when they are being used as a + vehicle for such an 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.) +

        +
      • +
      +

      + Statistics counters have also been added to track the number + of queries affected by these quotas. +

      +
    • +
    • +

      + Added support for dnstap, a fast, + flexible method for capturing and logging DNS traffic, + developed by Robert Edmonds at Farsight Security, Inc., + whose assistance is gratefully acknowledged. +

      +

      + To enable dnstap at compile time, + the fstrm and protobuf-c + libraries must be available, and BIND must be configured with + --enable-dnstap. +

      +

      + A new utility dnstap-read has been added + to allow dnstap data to be presented in + a human-readable format. +

      +

      + For more information on dnstap, see + http://dnstap.info. +

      +
    • +
    • +

      + New statistics counters have been added to track traffic + sizes, as specified in RSSAC002. Query and response + message sizes are broken up into ranges of histogram buckets: + TCP and UDP queries of size 0-15, 16-31, ..., 272-288, and 288+, + and TCP and UDP responses of size 0-15, 16-31, ..., 4080-4095, + and 4096+. These values can be accessed via the XML and JSON + statistics channels at, for example, + http://localhost:8888/xml/v3/traffic + or + http://localhost:8888/json/v1/traffic. +

      +
    • +
    • +

      + The serial number of a dynamically updatable zone can + now be set using + rndc signing -serial number zonename. + This is particularly useful with inline-signing + zones that have been reset. Setting the serial number to a value + larger than that on the slaves will trigger an AXFR-style + transfer. +

      +
    • +
    • +

      + When answering recursive queries, SERVFAIL responses can now be + cached by the server for a limited time; subsequent queries for + the same query name and type will return another SERVFAIL until + the cache times out. This reduces the frequency of retries + when a query is persistently failing, which can be a burden + on recursive serviers. The SERVFAIL cache timeout is controlled + by servfail-ttl, which defaults to 10 seconds + and has an upper limit of 30. +

      +
    • +
    • +

      + The new rndc nta command can now be used to + set a "negative trust anchor" (NTA), disabling DNSSEC validation for + a specific domain; this can be used when responses from a domain + are known to be failing validation due to administrative error + rather than because of a spoofing attack. NTAs are strictly + temporary; by default they expire after one hour, but can be + configured to last up to one week. The default NTA lifetime + can be changed by setting the nta-lifetime in + named.conf. When added, NTAs are stored in a + file (viewname.nta) + in order to persist across restarts of the named server. +

      +
    • +
    • +

      + The EDNS Client Subnet (ECS) option is now supported for + authoritative servers; if a query contains an ECS option then + ACLs containing geoip or ecs + elements can match against the the address encoded in the option. + This can be used to select a view for a query, so that different + answers can be provided depending on the client network. +

      +
    • +
    • +

      + The EDNS EXPIRE option has been implemented on the client + side, allowing a slave server to set the expiration timer + correctly when transferring zone data from another slave + server. +

      +
    • +
    • +

      + A new masterfile-style zone option controls + the formatting of text zone files: When set to + full, the zone file will dumped in + single-line-per-record format. +

      +
    • +
    • +

      + dig +ednsopt can now be used to set + arbitrary EDNS options in DNS requests. +

      +
    • +
    • +

      + dig +ednsflags can now be used to set + yet-to-be-defined EDNS flags in DNS requests. +

      +
    • +
    • +

      + dig +[no]ednsnegotiation can now be used enable / + disable EDNS version negotiation. +

      +
    • +
    • +

      + dig +header-only can now be used to send + queries without a question section. +

      +
    • +
    • +

      + dig +ttlunits causes dig + to print TTL values with time-unit suffixes: w, d, h, m, s for + weeks, days, hours, minutes, and seconds. +

      +
    • +
    • +

      + dig +zflag can be used to set the last + unassigned DNS header flag bit. This bit in normally zero. +

      +
    • +
    • +

      + dig +dscp=value + can now be used to set the DSCP code point in outgoing query + packets. +

      +
    • +
    • +

      + serial-update-method can now be set to + date. On update, the serial number will + be set to the current date in YYYYMMDDNN format. +

      +
    • +
    • +

      + dnssec-signzone -N date also sets the serial + number to YYYYMMDDNN. +

      +
    • +
    • +

      + named -L filename + causes named to send log messages to the specified file by + default instead of to the system log. +

      +
    • +
    • +

      + The rate limiter configured by the + serial-query-rate option no longer covers + NOTIFY messages; those are now separately controlled by + notify-rate and + startup-notify-rate (the latter of which + controls the rate of NOTIFY messages sent when the server + is first started up or reconfigured). +

      +
    • +
    • +

      + The default number of tasks and client objects available + for serving lightweight resolver queries have been increased, + and are now configurable via the new lwres-tasks + and lwres-clients options in + named.conf. [RT #35857] +

      +
    • +
    • +

      + Log output to files can now be buffered by specifying + buffered yes; when creating a channel. +

      +
    • +
    • +

      + delv +tcp will exclusively use TCP when + sending queries. +

      +
    • +
    • +

      + named will now check to see whether + other name server processes are running before starting up. + This is implemented in two ways: 1) by refusing to start + if the configured network interfaces all return "address + in use", and 2) by attempting to acquire a lock on a file + specified by the lock-file option or + the -X command line option. The + default lock file is + /var/run/named/named.lock. + Specifying none will disable the lock + file check. +

      +
    • +
    • +

      + rndc delzone can now be applied to zones + which were configured in named.conf; + it is no longer restricted to zones which were added by + rndc addzone. (Note, however, that + this does not edit named.conf; the zone + must be removed from the configuration or it will return + when named is restarted or reloaded.) +

      +
    • +
    • +

      + rndc modzone can be used to reconfigure + a zone, using similar syntax to rndc addzone. +

      +
    • +
    • +

      + rndc showzone displays the current + configuration for a specified zone. +

      +
    • +
    • +

      + Added server-side support for pipelined TCP queries. Clients + may continue sending queries via TCP while previous queries are + processed in parallel. Responses are sent when they are + ready, not necessarily in the order in which the queries were + received. +

      +

      + To revert to the former behavior for a particular + client address or range of addresses, specify the address prefix + in the "keep-response-order" option. To revert to the former + behavior for all clients, use "keep-response-order { any; };". +

      +
    • +
    • +

      + The new mdig command is a version of + dig that sends multiple pipelined + queries and then waits for responses, instead of sending one + query and waiting the response before sending the next. [RT #38261] +

      +
    • +
    • +

      + To enable better monitoring and troubleshooting of RFC 5011 + trust anchor management, the new 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 now has + easier-to-read comments. [RT #38458] +

      +
    • +
    • +

      + An --enable-querytrace configure switch is + now available to enable very verbose query tracelogging. This + option can only be set at compile time. This option has a + negative performance impact and should be used only for + debugging. [RT #37520] +

      +
    • +
    • +

      + A new tcp-only option can be specified + in server statements to force + named to connect to the specified + server via TCP. [RT #37800] +

      +
    • +
    • +

      + The nxdomain-redirect option specifies + a DNS namespace to use for NXDOMAIN redirection. When a + recursive lookup returns NXDOMAIN, a second lookup is + initiated with the specified name appended to the query + name. This allows NXDOMAIN redirection data to be supplied + by multiple zones configured on the server or by recursive + queries to other servers. (The older method, using + a single type redirect zone, has + better average performance but is less flexible.) [RT #37989] +

      +
    • +
    • +

      + The following types have been implemented: CSYNC, NINFO, RKEY, + SINK, TA, TALINK. +

      +
    • +
    +
    +
    +

    +Feature Changes

    + +
      +
    • +

      + ACLs containing geoip asnum elements were + not correctly matched unless the full organization name was + specified in the ACL (as in + geoip asnum "AS1234 Example, Inc.";). + They can now match against the AS number alone (as in + geoip asnum "AS1234";). +

      +
    • +
    • +

      + When using native PKCS#11 cryptography (i.e., + configure --enable-native-pkcs11) HSM PINs + of up to 256 characters can now be used. +

      +
    • +
    • +

      + NXDOMAIN responses to queries of type DS are now cached separately + from those for other types. This helps when using "grafted" zones + of type forward, for which the parent zone does not contain a + delegation, such as local top-level domains. Previously a query + of type DS for such a zone could cause the zone apex to be cached + as NXDOMAIN, blocking all subsequent queries. (Note: This + change is only helpful when DNSSEC validation is not enabled. + "Grafted" zones without a delegation in the parent are not a + recommended configuration.) +

      +
    • +
    • +

      + Update forwarding performance has been improved by allowing + a single TCP connection to be shared between multiple updates. +

      +
    • +
    • +

      + By default, nsupdate will now check + the correctness of hostnames when adding records of type + A, AAAA, MX, SOA, NS, SRV or PTR. This behavior can be + disabled with check-names no. +

      +
    • +
    • +

      + Added support for OPENPGPKEY type. +

      +
    • +
    • +

      + The names of the files used to store managed keys and added + zones for each view are no longer based on the SHA256 hash + of the view name, except when this is necessary because the + view name contains characters that would be incompatible with use + as a file name. For views whose names do not contain forward + slashes ('/'), backslashes ('\'), or capital letters - which + could potentially cause namespace collision problems on + case-insensitive filesystems - files will now be named + after the view (for example, internal.mkeys + or external.nzf). However, to ensure + consistent behavior when upgrading, if a file using the old + name format is found to exist, it will continue to be used. +

      +
    • +
    • +

      + "rndc" can now return text output of arbitrary size to + the caller. (Prior to this, certain commands such as + "rndc tsig-list" and "rndc zonestatus" could return + truncated output.) +

      +
    • +
    • +

      + Errors reported when running rndc addzone + (e.g., when a zone file cannot be loaded) have been clarified + to make it easier to diagnose problems. +

      +
    • +
    • +

      + When encountering an authoritative name server whose name is + an alias pointing to another name, the resolver treats + this as an error and skips to the next server. Previously + this happened silently; now the error will be logged to + the newly-created "cname" log category. +

      +
    • +
    • +

      + If named is not configured to validate the answer then + allow fallback to plain DNS on timeout even when we know + the server supports EDNS. This will allow the server to + potentially resolve signed queries when TCP is being + blocked. +

      +
    • +
    • +

      + Large inline-signing changes should be less disruptive. + Signature generation is now done incrementally; the number + of signatures to be generated in each quantum is controlled + by "sig-signing-signatures number;". + [RT #37927] +

      +
    • +
    • +

      + The experimental SIT option (code point 65001) of BIND + 9.10.0 through BIND 9.10.2 has been replaced with the COOKIE + option (code point 10). It is no longer experimental, and + is sent by default, by both named and + dig. +

      +

      + The SIT-related named.conf options have been marked as + obsolete, and are otherwise ignored. +

      +
    • +
    • +

      + When dig receives a truncated (TC=1) + response or a BADCOOKIE response code from a server, it + will automatically retry the query using the server COOKIE + that was returned by the server in its initial response. + [RT #39047] +

      +
    • +
    • +

      + A alternative NXDOMAIN redirect method (nxdomain-redirect) + which allows the redirect information to be looked up from + a namespace on the Internet rather than requiring a zone + to be configured on the server is now available. +

      +
    • +
    • +

      + Retrieving the local port range from net.ipv4.ip_local_port_range + on Linux is now supported. +

      +
    • +
    • +

      + Within the response-policy option, it is now + possible to configure RPZ rewrite logging on a per-zone basis + using the log clause. +

      +
    • +
    • +

      + The default preferred glue is now the address type of the + transport the query was received over. +

      +
    • +
    • +

      + On machines with 2 or more processors (CPU), the default value + for the number of UDP listeners has been changed to the number + of detected processors minus one. +

      +
    • +
    +
    +
    +

    +Porting Changes

    + +
    • +

      + The Microsoft Windows install tool + BINDInstall.exe which requires a + non-free version of Visual Studio to be built, now uses two + files (lists of flags and files) created by the Configure + perl script with all the needed information which were + previously compiled in the binary. Read + win32utils/build.txt for more details. + [RT #38915] +

      +
    +
    +
    +

    +Bug Fixes

    + +
      +
    • +

      + dig, host and + nslookup aborted when encountering + a name which, after appending search list elements, + exceeded 255 bytes. Such names are now skipped, but + processing of other names will continue. [RT #36892] +

      +
    • +
    • +

      + The error message generated when + named-checkzone or + named-checkconf -z encounters a + $TTL directive without a value has + been clarified. [RT #37138] +

      +
    • +
    • +

      + Semicolon characters (;) included in TXT records were + incorrectly escaped with a backslash when the record was + displayed as text. This is actually only necessary when there + are no quotation marks. [RT #37159] +

      +
    • +
    • +

      + When files opened for writing by named, + such as zone journal files, were referenced more than once + in named.conf, it could lead to file + corruption as multiple threads wrote to the same file. This + is now detected when loading named.conf + and reported as an error. [RT #37172] +

      +
    • +
    • +

      + When checking for updates to trust anchors listed in + managed-keys, named + now revalidates keys based on the current set of + active trust anchors, without relying on any cached + record of previous validation. [RT #37506] +

      +
    • +
    • +

      + Large-system tuning + (configure --with-tuning=large) caused + problems on some platforms by setting a socket receive + buffer size that was too large. This is now detected and + corrected at run time. [RT #37187] +

      +
    • +
    • +

      + When NXDOMAIN redirection is in use, queries for a name + that is present in the redirection zone but a type that + is not present will now return NOERROR instead of NXDOMAIN. +

      +
    • +
    • +

      + Due to an inadvertent removal of code in the previous + release, when named encountered an + authoritative name server which dropped all EDNS queries, + it did not always try plain DNS. This has been corrected. + [RT #37965] +

      +
    • +
    • +

      + A regression caused nsupdate to use the default recursive servers + rather than the SOA MNAME server when sending the UPDATE. +

      +
    • +
    • +

      + Adjusted max-recursion-queries to accommodate the smaller + initial packet sizes used in BIND 9.10 and higher when + contacting authoritative servers for the first time. +

      +
    • +
    • +

      + Built-in "empty" zones did not correctly inherit the + "allow-transfer" ACL from the options or view. [RT #38310] +

      +
    • +
    • +

      + Two leaks were fixed that could cause named + processes to grow to very large sizes. [RT #38454] +

      +
    • +
    • +

      + Fixed some bugs in RFC 5011 trust anchor management, + including a memory leak and a possible loss of state + information. [RT #38458] +

      +
    • +
    • +

      + 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] +

      +
    • +
    • +

      + A race during shutdown or reconfiguration could + cause an assertion failure in mem.c. [RT #38979] +

      +
    • +
    • +

      + Some answer formatting options didn't work correctly with + dig +short. [RT #39291] +

      +
    • +
    • +

      + Several bugs have been fixed in the RPZ implementation: +

      +
        +
      • +

        + Policy zones that did not specifically require recursion + could be treated as if they did; consequently, setting + qname-wait-recurse no; was + sometimes ineffective. This has been corrected. + In most configurations, behavioral changes due to this + fix will not be noticeable. [RT #39229] +

        +
      • +
      • +

        + The server could crash if policy zones were updated (e.g. + via rndc reload or an incoming zone + transfer) while RPZ processing was still ongoing for an + active query. [RT #39415] +

        +
      • +
      • +

        + On servers with one or more policy zones configured as + slaves, if a policy zone updated during regular operation + (rather than at startup) using a full zone reload, such as + via AXFR, a bug could allow the RPZ summary data to fall out + of sync, potentially leading to an assertion failure in + rpz.c when further incremental updates were made to the + zone, such as via IXFR. [RT #39567] +

        +
      • +
      • +

        + The server could match a shorter prefix than what was + available in CLIENT-IP policy triggers, and so, an + unexpected action could be taken. This has been + corrected. [RT #39481] +

        +
      • +
      • +

        + The server could crash if a reload of an RPZ zone was + initiated while another reload of the same zone was + already in progress. [RT #39649] +
