# Significant Changes in BIND9 package
## BIND 9.16
### New features
- *libuv* is used for network subsystem as a mandatory dependency
- *dnssec-policy* support in named.conf is introduced, providing a a key and signing policy
([KASP](https://gitlab.isc.org/isc-projects/bind9/-/wikis/DNSSEC-Key-and-Signing-Policy-(KASP)))
- *trusted-keys* and *managed-keys* are deprecated, replaced by *trust-anchors*
- *trust-anchors* support also anchor in a *DS* format, in addition to *DNSKEY* format
- **dig, mdig** and **delv** support **+yaml** parameter to print detailed machine parseable output
### Feature changes
- Static trust anchor and *dnssec-validation auto;* are incompatible and cause fatal error, when used together.
- *DS* and *CDS* now generates only SHA-256 digest, SHA-1 is no longer generated by default
- SipHash 2-4 DNS Cookie ([RFC 7873](https://www.rfc-editor.org/rfc/rfc7873.html) is now default).
Only AES alternative algorithm is kept, HMAC-SHA cookie support were removed.
- **dnssec-signzone** and **dnssec-verify** commands print output to stdout, *-q* parameter can silence them
### Features removed
- *dnssec-enable* option is obsolete, DNSSEC support is always enabled
- *dnssec-lookaside* option is deprecated and support for it removed from all tools
- *cleaning-interval* option is removed
### Upstream release notes
- [9.16.10 notes](https://downloads.isc.org/isc/bind9/9.16.10/doc/arm/html/notes.html#notes-for-bind-9-16-10)
- [9.16.0 notes](https://downloads.isc.org/isc/bind9/9.16.0/doc/arm/html/notes.html#notes-for-bind-9-16-0)
## BIND 9.14
- single thread support removed. Cannot provide *bind-export-libs* for DHCP
- *lwres* support completely removed. Both daemon and library
- common parts of daemon moved into *libns* shared library
- introduced plugin for filtering aaaa responses
- some SDB utilities no longer supported
### Upstream release notes
- [9.14.7 notes](https://downloads.isc.org/isc/bind9/9.14.7/RELEASE-NOTES-bind-9.14.7.html)

# BIND 9
[BIND (Berkeley Internet Name Domain)](https://www.isc.org/downloads/bind/doc/) is a complete, highly portable
implementation of the DNS (Domain Name System) protocol.
Internet Systems Consortium
([https://www.isc.org](https://www.isc.org)), a 501(c)(3) public benefit
corporation dedicated to providing software and services in support of the
Internet infrastructure, developed BIND 9 and is responsible for its
ongoing maintenance and improvement.
More details about upstream project can be found on their
[gitlab](https://gitlab.isc.org/isc-projects/bind9). This repository contains
only upstream sources and packaging instructions for
[Fedora Project](https://fedoraproject.org).
## Subpackages
The package contains several subpackages, some of them can be disabled on rebuild.
* **bind** -- *named* daemon providing DNS server
* **bind-utils** -- set of tools to analyse DNS responses or update entries (dig, host)
* **bind-doc** -- documentation for current bind, *BIND 9 Administrator Reference Manual*.
* **bind-license** -- Shared license for all packages but bind-export-libs.
* **bind-libs** -- Shared libraries used by some others programs
* **bind-devel** -- Development headers for libs. Can be disabled by `--without DEVEL`
## Optional features
* *GSSTSIG* -- Support for Kerberos authentication in BIND.
* *LMDB* -- Support for dynamic database for managing runtime added zones. Provides faster removal of added zone with much less overhead. But requires lmdb linked to base libs.
* *DLZ* -- Support for dynamic loaded modules providing support for features *bind-sdb* provides, but only small module is required.

PGSQL BIND SDB driver
The postgresql BIND SDB driver is of experimental status and should not be
used for production systems.
Usage:
o Use the named_sdb process ( put ENABLE_SDB=yes in /etc/sysconfig/named )
o Edit your named.conf to contain a database zone, eg. :
zone "pgdb.net." IN {
type master;
database "pgsql bind pgdb localhost pguser pgpasswd";
# ^- DB name ^-Table ^-host ^-user ^-password
};
o Create the database zone table
The table must contain the columns "name", "rdtype", and "rdata", and
is expected to contain a properly constructed zone. The program "zonetodb"
creates such a table.
zonetodb usage:
zonetodb origin file dbname dbtable
where
origin : zone origin, eg "pgdb.net."
file : master zone database file, eg. pgdb.net.db
dbname : name of postgresql database
dbtable: name of table in database
Eg. to import this zone in the file 'pgdb.net.db' into the 'bind' database
'pgdb' table:
---
#pgdb.net.db:
$TTL 1H
@ SOA localhost. root.localhost. ( 1
3H
1H
1W
1H )
NS localhost.
host1 A 192.168.2.1
host2 A 192.168.2.2
host3 A 192.168.2.3
host4 A 192.168.2.4
host5 A 192.168.2.5
host6 A 192.168.2.6
host7 A 192.168.2.7
---
Issue this command as the pgsql user authorized to update the bind database:
# zonetodb pgdb.net. pgdb.net.db bind pgdb
will create / update the pgdb table in the 'bind' db:
$ psql -dbind -c 'select * from pgdb;'
name | ttl | rdtype | rdata
----------------+------+--------+-----------------------------------------------------
pgdb.net | 3600 | SOA | localhost. root.localhost. 1 10800 3600 604800 3600
pgdb.net | 3600 | NS | localhost.
host1.pgdb.net | 3600 | A | 192.168.2.1
host2.pgdb.net | 3600 | A | 192.168.2.2
host3.pgdb.net | 3600 | A | 192.168.2.3
host4.pgdb.net | 3600 | A | 192.168.2.4
host5.pgdb.net | 3600 | A | 192.168.2.5
host6.pgdb.net | 3600 | A | 192.168.2.6
host7.pgdb.net | 3600 | A | 192.168.2.7
(9 rows)
I've tested exactly the above configuration with bind-sdb-9.3.1+ and it works OK.
NOTE: If you use pgsqldb SDB, ensure the postgresql service is started before the named
service .
USE AT YOUR OWN RISK!

From 1f5cb247ecd20ba57c472138f94856aa83caf042 Mon Sep 17 00:00:00 2001
From: Mark Andrews <marka@isc.org>
Date: Tue, 1 Mar 2022 09:48:05 +1100
Subject: [PATCH] Add additional name checks when using a forwarder
When using a forwarder, check that the owner name of response
records are within the bailiwick of the forwarded name space.
(cherry picked from commit e8df2802ac62016ea68585893eb4310fc3329028)
Check that the forward declaration is unchanged and not overridden
If we are using a fowarder, in addition to checking that names to
be cached are subdomains of the forwarded namespace, we must also
check that there are no subsidiary forwarded namespaces which would
take precedence. To be safe, we don't cache any responses if the
forwarding configuration has changed since the query was sent.
(cherry picked from commit 590f8698fc876d6d72f75cf35359e7546c3af972)
Check cached names for possible "forward only" clause
When caching additional and glue data *not* from a forwarder, we must
check that there is no "forward only" clause covering the owner name
that would take precedence. Such names would normally be allowed by
baliwick rules, but a "forward only" zone introduces a new baliwick
scope.
(cherry picked from commit 4a144fae16e70517be894a971cef1d085ee68ebe)
Look for zones deeper than the current domain or forward name
When caching glue, we need to ensure that there is no closer
source of truth for the name. If the owner name for the glue
record would be answered by a locally configured zone, do not
cache.
(cherry picked from commit 42f8c538d3fb9d075b98d82688aeb71621798754)
Avoid use of compound literals
Compound literals are not used in BIND 9.11, in order to ensure backward
compatibility with ancient compilers. Rework the relevant parts of the
BIND 9.11 backport of the CVE-2021-25220 fix so that compound literals
are not used.
(cherry picked from commit d4b1efbcbd4dfb8c6ef303968992440c5bdeed15)

Subject: [PATCH] Bound the amount of work performed for delegations
Limit the amount of database lookups that can be triggered in
fctx_getaddresses() (i.e. when determining the name server addresses to
query next) by setting a hard limit on the number of NS RRs processed
for any delegation encountered. Without any limit in place, named can
be forced to perform large amounts of database lookups per each query
received, which severely impacts resolver performance.
The limit used (20) is an arbitrary value that is considered to be big
enough for any sane DNS delegation.

Subject: [PATCH] Improve RBT overmem cache cleaning
When cache memory usage is over the configured cache size (overmem) and
we are cleaning unused entries, it might not be enough to clean just two
entries if the entries to be expired are smaller than the newly added
rdata. This could be abused by an attacker to cause a remote Denial of
Service by possibly running out of the operating system memory.
Currently, the addrdataset() tries to do a single TTL-based cleaning
considering the serve-stale TTL and then optionally moves to overmem
cleaning if we are in that condition. Then the overmem_purge() tries to
do another single TTL based cleaning from the TTL heap and then continue
with LRU-based cleaning up to 2 entries cleaned.
Squash the TTL-cleaning mechanism into single call from addrdataset(),
but ignore the serve-stale TTL if we are currently overmem.
Then instead of having a fixed number of entries to clean, pass the size
of newly added rdatasetheader to the overmem_purge() function and
cleanup at least the size of the newly added data. This prevents the
cache going over the configured memory limit (`max-cache-size`).
Additionally, refactor the overmem_purge() function to reduce for-loop
nesting for readability.

Subject: [PATCH] Fail the DNSSEC validation on the first failure
Be more strict when encountering DNSSEC validation failures - fail on
the first failure. This will break domains that have DNSSEC signing
keys with duplicate key ids, but this is something that's much easier
to fix on the authoritative side, so we are just going to be strict
on the resolver side where it is causing performance problems.
(cherry picked from commit 8b7ecba9885e163c07c2dd3e1ceab79b2ba89e34)
Add normal and slow task queues
Split the task manager queues into normal and slow task queues, so we
can move the tasks that blocks processing for a long time (like DNSSEC
validation) into the slow queue which doesn't block fast
operations (like responding from the cache). This mitigates the whole
class of KeyTrap-like issues.
(cherry picked from commit db083a21726300916fa0b9fd8a433a796fedf636)
Don't iterate from start every time we select new signing key
Improve the selecting of the new signing key by remembering where
we stopped the iteration and just continue from that place instead
of iterating from the start over and over again each time.
(cherry picked from commit 75faeefcab47e4f1e12b358525190b4be90f97de)
Optimize selecting the signing key
Don't parse the crypto data before parsing and matching the id and the
algorithm.
(cherry picked from commit b38552cca7200a72658e482f8407f57516efc5db)
6322. [security] Specific DNS answers could cause a denial-of-service
condition due to DNS validation taking a long time.
(CVE-2023-50387) [GL #4424]
The same code change also addresses another problem:
preparing NSEC3 closest encloser proofs could exhaust
available CPU resources. (CVE-2023-50868) [GL #4459]

Subject: [PATCH] Allow global runtime definition by DNS_RBTDB_MAX_RTYPES
Modify rbtdb to not set it only at runtime, but allow setting that also
in runtime via environment variable. It is still possible to modify
default during the build define. In addition to it allows runtime change
also. Can be positive number to set limit, 0 disabled the check.
Similarly add also DNS_RDATASET_MAX_RECORDS to set maximum number of
records for a single name. This must be positive number, 0 is no accepted.
These replaces max-records-per-type and max-types-per-name in later
versions. But can be configured only by environment and can be
configured only globally, not in each view or zone.

Subject: [PATCH] [9.11][CVE-2024-1737] Add a limit to the number of RRs in
RRSets
Add a limit to the number of RRs in RRSets
Previously, the number of RRs in the RRSets were internally unlimited.
As the data structure that holds the RRs is just a linked list, and
there are places where we just walk through all of the RRs, adding an
RRSet with huge number of RRs inside would slow down processing of said
RRSets.
The fix for end-of-life branches make the limit compile-time only for
simplicity and the limit can be changed at the compile time by adding
following define to CFLAGS:
-DDNS_RDATASET_MAX_RECORDS=<limit>
(cherry picked from commit c5c4d00c38530390c9e1ae4c98b65fbbadfe9e5e)
(cherry picked from commit 7f705778af729ada7fec36ac4b456c73329bd996)
(cherry picked from commit b9b5485b22c364fb88c27aa04bad4c8f616da3fa)
Add a limit to the number of RR types for single name
Previously, the number of RR types for a single owner name was limited
only by the maximum number of the types (64k). As the data structure
that holds the RR types for the database node is just a linked list, and
there are places where we just walk through the whole list (again and
again), adding a large number of RR types for a single owner named with
would slow down processing of such name (database node).
Add a hard-coded limit (100) to cap the number of the RR types for a single
owner. The limit can be changed at the compile time by adding following
define to CFLAGS:
-DDNS_RBTDB_MAX_RTYPES=<limit>
(cherry picked from commit 538b843d84f49ba5125ff545e3d0cf1c8434a8f2)
(cherry picked from commit 3f10d6eff035702796ba82cd28b9f7cf9836e743)
Optimize the slabheader placement for certain RRTypes
Mark the infrastructure RRTypes as "priority" types and place them at
the beginning of the rdataslab header data graph. The non-priority
types either go right after the priority types (if any).
(cherry picked from commit 3ac482be7fd058d284e89873021339579fad0615)
(cherry picked from commit 23a4652346fb2877d6246b1eebaa967969dbde16)
[9.11][CVE-2024-1737 (part 2)] Be smarter about refusing to add many RR types to the database
Expand the list of the priority types
Add HTTPS, SVCB, SRV, PTR, NAPTR, DNSKEY and TXT records to the list of
the priority types that are put at the beginning of the slabheader list
for faster access and to avoid eviction when there are more types than
the max-types-per-name limit.
(cherry picked from commit b27c6bcce894786a8e082eafd59eccbf6f2731cb)
(cherry picked from commit 3e0a67e4bdb253dae3a03a45c1aa117239a3313d)
Be smarter about refusing to add many RR types to the database
Instead of outright refusing to add new RR types to the cache, be a bit
smarter:
1. If the new header type is in our priority list, we always add either
positive or negative entry at the beginning of the list.
2. If the new header type is negative entry, and we are over the limit,
we mark it as ancient immediately, so it gets evicted from the cache
as soon as possible.
3. Otherwise add the new header after the priority headers (or at the
head of the list).
4. If we are over the limit, evict the last entry on the normal header
list.
(cherry picked from commit 57cd34441a1b4ecc9874a4a106c2c95b8d7a3120)
(cherry picked from commit e4d7ce686bb38428eddc7e33b40057d68eca9a6e)

Subject: [PATCH] Allow explicit disabling of autodisabled MD5
Default security policy might include explicitly disabled RSAMD5
algorithm. Current FIPS code automatically disables in FIPS mode. But if
RSAMD5 is included in security policy, it fails to start, because that
algorithm is not recognized. Allow it disabled, but fail on any

Subject: [PATCH] Disable IDN from environment as documented
Manual page of host contained instructions to disable IDN processing
when it was built with libidn2. When refactoring IDN support however,
support for disabling IDN in host and nslookup was lost. Use also
environment variable and document it for nslookup, host and dig.
Support variable CHARSET=ASCII to disable IDN, supported in downstream
RH patch since RHEL 5.

Do not test random entropy on startup when used by DHCP. On most cases
random entropy is not even used by DHCP. In cases it is (LDAP SSL), fail
whenever it is not available.

Subject: [PATCH] Use proper entropy to initialize tsig keyname
Random names used on GSS backed nsupdate can conflict in specific
situations. That might include starting a lot of machines from
containers, where they took all similar time to start. PID and timestamp
would be similar and therefore randomness is quite low. Use entropy to
generate more random identifier and reduce chance of conflict.

Subject: [PATCH] Have dns_zt_apply lock the zone table
There where a number of places where the zone table should have
been locked, but wasn't, when dns_zt_apply was called.
Added a isc_rwlocktype_t type parameter to dns_zt_apply and adjusted
all calls to using it. Removed locks in callers.
Modified upstream commit for v9_11

Subject: [PATCH] Add include to rwlocktype_t to dns/zt.h
It got broken as part of bug #2101712 fix. Introduced new definition,
which passes during bind build, but breaks bind-dyndb-ldap build.

From af3b530773231f8cff6548e36962ad1f25e38c5d Mon Sep 17 00:00:00 2001
From: Evan Hunt <each@isc.org>
Date: Thu, 28 Sep 2017 10:09:22 -0700
Subject: [PATCH] completed and corrected the crypto-random change
4724. [func] By default, BIND now uses the random number
functions provided by the crypto library (i.e.,
OpenSSL or a PKCS#11 provider) as a source of
randomness rather than /dev/random. This is
suitable for virtual machine environments
which have limited entropy pools and lack
hardware random number generators.
This can be overridden by specifying another
entropy source via the "random-device" option
in named.conf, or via the -r command line option;
however, for functions requiring full cryptographic
strength, such as DNSSEC key generation, this
cannot be overridden. In particular, the -r
command line option no longer has any effect on
dnssec-keygen.
This can be disabled by building with
"configure --disable-crypto-rand".

Subject: [PATCH] Do not keep stale records by default
By default set max-stale-ttl to 0, unless stale-answer-enable yes. This
were enabled by mistake when backporting fix for CVE-2023-2828. It
causes increased cache usage on servers not wanting to serve stale
records. Fix that by setting smart defaults based on stale answers
enabled with possible manual tuning.

It fails too often on some architecture, failing the whole build along.
Because it runs two times for pkcs11 and normal build and any of
subtests can occasionally fail, stop it.
It can be used again by defining 'unstable' variable in Kyuafile.

Subject: [PATCH] Use RESOLVER_NTASKS_PERCPU - 32 for regular tuning, 8 for
small
Modify original upstream commit 0d80266f7e3, add high limit of used
tasks. Minimum would be lower on machines with few cpus, but maximum
would stay unchanged. Should prevent negatives of this change.

Subject: [PATCH] add an update quota
limit the number of simultaneous DNS UPDATE events that can be
processed by adding a quota for update and update forwarding.
this quota currently, arbitrarily, defaults to 100.
also add a statistics counter to record when the update quota
has been exceeded.

Subject: [PATCH] move update ACL and update-policy checks before quota
check allow-update, update-policy, and allow-update-forwarding before
consuming quota slots, so that unauthorized clients can't fill the
quota.
(this moves the access check before the prerequisite check, which
violates the precise wording of RFC 2136. however, RFC co-author Paul
Vixie has stated that the RFC is mistaken on this point; it should have
said that access checking must happen *no later than* the completion of
prerequisite checks, not that it must happen exactly then.)
(cherry picked from commit 964f559edb5036880b8e463b8f190b9007ee055d)

From 3d84c651f823cb90b73fd736d32ad6de57b11610 Mon Sep 17 00:00:00 2001
From: Evan Hunt <each@isc.org>
Date: Wed, 9 Nov 2022 21:56:16 -0800
Subject: [PATCH] test failure conditions
verify that updates are refused when the client is disallowed by
allow-query, and update forwarding is refused when the client is
is disallowed by update-forwarding.
verify that "too many DNS UPDATEs" appears in the log file when too
many simultaneous updates are processing.
(cherry picked from commit b91339b80e5b82a56622c93cc1e3cca2d0c11bc0)

+
+ <para>
+ By default, Red Hat ships BIND with the most secure SELinux policy
+ that will not prevent normal BIND operation and will prevent exploitation
+ of all known BIND security vulnerabilities . See the selinux(8) man page
+ for information about SElinux.
+ </para>
+
+ <para>
+ It is not necessary to run named in a chroot environment if the Red Hat
+ SELinux policy for named is enabled. When enabled, this policy is far
+ more secure than a chroot environment. Users are recommended to enable
+ SELinux and remove the bind-chroot package.
+ </para>
+
+ <para>
+ With this extra security comes some restrictions:
+ </para>
+
+ <para>
+ By default, the SELinux policy allows named to write any master
+ zone database files. Only the root user may create files in the $ROOTDIR/var/named
+ zone database file directory (the options { "directory" } option), where
+ $ROOTDIR is set in /etc/sysconfig/named.
+ </para>
+
+ <para>
+ The "named" group must be granted read privelege to
+ these files in order for named to be enabled to read them.
+ </para>
+
+ <para>
+ Any file created in the zone database file directory is automatically assigned
+ the SELinux file context named_zone_t .
+ </para>
+
+ <para>
+ By default, SELinux prevents any role from modifying named_zone_t files; this
+ means that files in the zone database directory cannot be modified by dynamic
+ DNS (DDNS) updates or zone transfers.
+ </para>
+
+ <para>
+ The Red Hat BIND distribution and SELinux policy creates three directories where
+ named is allowed to create and modify files: /var/named/slaves, /var/named/dynamic
+ /var/named/data. By placing files you want named to modify, such as
+ slave or DDNS updateable zone files and database / statistics dump files in
+ these directories, named will work normally and no further operator action is
+ required. Files in these directories are automatically assigned the 'named_cache_t'
+ file context, which SELinux allows named to write.
+ </para>
+ </refsection>
+
+ <refsection><info><title>Red Hat BIND SDB support</title></info>
+
+ <para>
+ Red Hat ships named with compiled in Simplified Database Backend modules that ISC
+ provides in the "contrib/sdb" directory. Install bind-sdb package if you want use them.
+ </para>

+ The SDB modules for LDAP, PostGreSQL, DirDB and SQLite are compiled into <command>named-sdb</command>.
