Introduction
BIND 9.6-ESV-R9-P1 is the latest production release of BIND 9.6-ESV.
Security Fixes
Prevents exploitation of a runtime_check which can crash named
when satisfying a recursive query for particular malformed zones.
(CVE-2013-3919) [RT #33690]
Prevents a named assert (crash) when validating caused by using
"Bad cache" data before it has been initialized. [CVE-2012-3817]
[RT #30025]
A condition has been corrected where improper handling of
zero-length RDATA could cause undesirable behavior, including
termination of the named process. [CVE-2012-1667] [RT #29644]
New Features
Adds a new configuration option, "check-spf"; valid values are
"warn" (default) and "ignore". When set to "warn", checks SPF
and TXT records in spf format, warning if either resource record
type occurs without a corresponding record of the other resource
record type. [RT #33355]
Adds support for Uniform Resource Identifier (URI) resource
records. [RT #23386]
Adds support for Host Identity Protocol (HIP) resource records
[RT #19384]
Adds support for the EUI48 and EUI64 RR types. [RT #33082]
Adds support for the RFC 6742 ILNP record types (NID, LP, L32,
and L64). [RT #31836]
The contributed queryperf utility has been improved, now retaining
better round trip time statistics. [RT #30128]
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
COMMENT should not be longer than 70 characters.
COMMENT should not begin with 'A'.
COMMENT should not begin with 'An'.
COMMENT should not begin with 'a'.
COMMENT should not end with a period.
COMMENT should start with a capital letter.
pkglint warnings. Some files also got minor formatting, spelling, and style
corrections.
Here are change changes from release note. Note security fixes except
CVE-2012-5166 should be already fixed in previous version of bind96 package.
Please refer https://kb.isc.org/article/AA-00795 for list of full bug fixes.
Security Fixes
* A deliberately constructed combination of records could cause named to hang
while populating the additional section of a response. [CVE-2012-5166] [RT
#31090]
* Prevents a named assert (crash) when queried for a record whose RDATA
exceeds 65535 bytes [CVE-2012-4244] [RT #30416]
* Prevents a named assert (crash) when validating caused by using "Bad cache"
data before it has been initialized. [CVE-2012-3817] [RT #30025]
* A condition has been corrected where improper handling of zero-length RDATA
could cause undesirable behavior, including termination of the named
process. [CVE-2012-1667] [RT #29644]
New Features
None
Feature Changes
* Improves OpenSSL error logging [RT #29932]
* nslookup now returns a nonzero exit code when it is unable to get an answer.
[RT #29492]
--- 9.6-ESV-R7-P3 released ---
3364. [security] Named could die on specially crafted record.
[RT #30416]
3358 [bug] Fix declaration of fatal in bin/named/server.c
and bin/nsupdate/main.c. [RT #30522]
--- 9.6-ESV-R7-P2 released ---
3346. [security] Bad-cache data could be used before it was
initialized, causing an assert. [RT #30025]
3343. [bug] Relax isc_random_jitter() REQUIRE tests. [RT #29821]
3342. [bug] Change #3314 broke saving of stub zones to disk
resulting in excessive cpu usage in some cases.
[RT #29952]
Security release for CVE-2012-1667.
--- 9.6-ESV-R7-P1 released ---
3331. [security] dns_rdataslab_fromrdataset could produce bad
rdataslabs. [RT #29644]
New Features
* None
Feature Changes
* BIND now recognizes the TLSA resource record type, created to
support IETF DANE (DNS-based Authentication of Named Entities)
[RT #28989]
Bug Fixes
* The locking strategy around the handling of iterative queries
has been tuned to reduce unnecessary contention in a multi-threaded
environment. (Note that this may not provide a measurable
improvement over previous versions of BIND, but it corrects the
performance impact of change 3309 / RT #27995) [RT #29239]
* Addresses a race condition that can cause named to to crash when
the masters list for a zone is updated via rndc reload/reconfig
[RT #26732]
* Fixes a race condition in zone.c that can cause named to crash
during the processing of rndc delzone [RT #29028]
* Prevents a named segfault from resolver.c due to procedure
fctx_finddone() not being thread-safe. [RT #27995]
* Uses hmctx, not mctx when freeing rbtdb->heaps to avoid triggering
an assertion when flushing cache data. [RT #28571]
* Resolves inconsistencies in locating DNSSEC keys where zone names
contain characters that require special mappings [RT #28600]
* A new flag -R has been added to queryperf for running tests
using non-recursive queries. It also now builds correctly on
MacOS version 10.7 (darwin) [RT #28565]
* Named no longer crashes if gssapi is enabled in named.conf but
was not compiled into the binary [RT #28338]
* SDB now handles unexpected errors from back-end database drivers
gracefully instead of exiting on an assert. [RT #28534]
Security Fixes
+ BIND 9 nameservers performing recursive queries could cache an
invalid record and subsequent queries for that record could
crash the resolvers with an assertion failure. [RT #26590]
[CVE-2011-4313]
Feature Changes
+ Improves initial start-up and server reload time by increasing
the default size of the hash table the configuration parser
uses to keep track of loaded zones and allowing it to grow
dynamically to better handle systems with large numbers of
zones. [RT #26523]
+ --enable-developer, a new composite argument to the configure
script, enables a set of build options normally disabled but
frequently selected in test or development builds, specifically:
enable_fixed_rrset, with_atf, enable_filter_aaaa, enable_rpz_nsip,
enable_rpz_nsdname, and with_dlz_filesystem (and on Linux and
Darwin, also enable_exportlib) [RT #27103]
* BIND 9 nameservers performing recursive queries could cache an invalid
record and subsequent queries for that record could crash the resolvers
with an assertion failure. [RT #26590]

New Features
9.6-ESV-R5
* Added a tool able to generate malformed packets to allow testing of
how named handles them. [RT #24096]
Security Fixes
9.6-ESV-R5
* named, set up to be a caching resolver, is vulnerable to a user
querying a domain with very large resource record sets (RRSets)
when trying to negatively cache the response. Due to an off-by-one
error, caching the response could cause named to crash. [RT #24650]
[CVE-2011-1910]
* Change #2912 populated the message section in replies to UPDATE
requests, which some Windows clients wanted. This exposed a latent
bug that allowed the response message to crash named. With this
fix, change 2912 has been reduced to copy only the zone section to
the reply. A more complete fix for the latent bug will be released
later. [RT #24777]
Feature Changes
9.6-ESV-R5
* Merged in the NetBSD ATF test framework (currently version 0.12)
for development of future unit tests. Use configure --with-atf to
build ATF internally or configure --with-atf=prefix to use an
external copy. [RT #23209]
* Added more verbose error reporting from DLZ LDAP. [RT #23402]
* Replaced compile time constant with STDTIME_ON_32BITS. [RT #23587]
The package name was selected as:
- Make sure to greater version from bind-9.6.3.
- Include "ESV" (Extended Support Version) string.
Since changes from BIND 9.6.3 are too may, please refer changes in detail:

9.6.3
* BIND now builds with threads disabled in versions of NetBSD earlier
than 5.0 and with pthreads enabled by default in NetBSD versions
5.0 and higher. Also removes support for unproven-pthreads,
mit-pthreads and ptl2. [RT #19203]
* HPUX now correctly defaults to using /dev/poll, which should
increase performance. [RT #21919]
* If named is running as a threaded application, after an "rndc stop"
command has been issued, other inbound TCP requests can cause named
to hang and never complete shutdown. [RT #22108]
* When performing a GSS-TSIG signed dynamic zone update, memory could
be leaked. This causes an unclean shutdown and may affect
long-running servers. [RT #22573]
* A bug in NetBSD and FreeBSD kernels with SO_ACCEPTFILTER enabled
allows for a TCP DoS attack. Until there is a kernel fix, ISC is
disabling SO_ACCEPTFILTER support in BIND. [RT #22589]
* Corrected a defect where a combination of dynamic updates and zone
transfers incorrectly locked the in-memory zone database, causing
named to freeze. [RT #22614]
* Don't run MX checks (check-mx) when the MX record points to ".".
[RT #22645]
* DST key reference counts can now be incremented via dst_key_attach.
[RT #22672]
* isc_mutex_init_errcheck() in phtreads/mutex.c failed to destroy
attr. [RT #22766]
* The Kerberos realm was being truncated when being pulled from the
the host prinicipal, make krb5-self updates fail. [RT #22770]
* named failed to preserve the case of domain names in RDATA which is
not compressible when writing master files. [RT #22863]
* There was a bug in how the clients-per-query code worked with some
query patterns. This could result, in rare circumstances, in having
all the client query slots filled with queries for the same DNS
label, essentially ignoring the max-clients-per-query setting. [RT
#22972]
--- 9.6.1-P3 released ---
2831. [security] Do not attempt to validate or cache
out-of-bailiwick data returned with a secure
answer; it must be re-fetched from its original
source and validated in that context. [RT #20819]
2828. [security] Cached CNAME or DNAME RR could be returned to clients
without DNSSEC validation. [RT #20737]
2827. [security] Bogus NXDOMAIN could be cached as if valid. [RT #20712]
--- 9.6.1-P2 released ---
2772. [security] When validating, track whether pending data was from
the additional section or not and only return it if
validates as secure. [RT #20438]
Based on PR 41772 by Robert Elz.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
