Import bind-9.16.15
Changes since bind-9.16.12:
--- 9.16.15 released ---
5621. [bug] Due to a backporting mistake in change 5609, named
binaries built against a Kerberos/GSSAPI library whose
header files did not define the GSS_SPNEGO_MECHANISM
preprocessor macro were not able to start if their
configuration included the "tkey-gssapi-credential"
option. This has been fixed. [GL #2634]
5620. [bug] If zone journal files written by BIND 9.16.11 or earlier
were present when BIND was upgraded, the zone file for
that zone could have been inadvertently rewritten with
the current zone contents. This caused the original zone
file structure (e.g. comments, $INCLUDE directives) to
be lost, although the zone data itself was preserved.
This has been fixed. [GL #2623]
--- 9.16.14 released ---
5617. [security] A specially crafted GSS-TSIG query could cause a buffer
overflow in the ISC implementation of SPNEGO.
(CVE-2021-25216) [GL #2604]
5616. [security] named crashed when a DNAME record placed in the ANSWER
section during DNAME chasing turned out to be the final
answer to a client query. (CVE-2021-25215) [GL #2540]
5615. [security] Insufficient IXFR checks could result in named serving a
zone without an SOA record at the apex, leading to a
RUNTIME_CHECK assertion failure when the zone was
subsequently refreshed. This has been fixed by adding an
owner name check for all SOA records which are included
in a zone transfer. (CVE-2021-25214) [GL #2467]
5614. [bug] Ensure all resources are properly cleaned up when a call
to gss_accept_sec_context() fails. [GL #2620]
5613. [bug] It was possible to write an invalid transaction header
in the journal file for a managed-keys database after
upgrading. This has been fixed. Invalid headers in
existing journal files are detected and named is able
to recover from them. [GL #2600]
5611. [func] Set "stale-answer-client-timeout" to "off" by default.
[GL #2608]
5610. [bug] Prevent a crash which could happen when a lookup
triggered by "stale-answer-client-timeout" was attempted
right after recursion for a client query finished.
[GL #2594]
5609. [func] The ISC implementation of SPNEGO was removed from BIND 9
source code. It was no longer necessary as all major
contemporary Kerberos/GSSAPI libraries include support
for SPNEGO. [GL #2607]
5608. [bug] When sending queries over TCP, dig now properly handles
"+tries=1 +retry=0" by not retrying the connection when
the remote server closes the connection prematurely.
[GL #2490]
5607. [bug] As "rndc dnssec -checkds" and "rndc dnssec -rollover"
commands may affect the next scheduled key event,
reconfiguration of zone keys is now triggered after
receiving either of these commands to prevent
unnecessary key rollover delays. [GL #2488]
5606. [bug] CDS/CDNSKEY DELETE records are now removed when a zone
transitions from a secure to an insecure state.
named-checkzone also no longer reports an error when
such records are found in an unsigned zone. [GL #2517]
5605. [bug] "dig -u" now uses the CLOCK_REALTIME clock source for
more accurate time reporting. [GL #2592]
5603. [bug] Fix a memory leak that occurred when named failed to
bind a UDP socket to a network interface. [GL #2575]
5602. [bug] Fix TCPDNS and TLSDNS timers in Network Manager. This
makes the "tcp-initial-timeout" and "tcp-idle-timeout"
options work correctly again. [GL #2583]
5601. [bug] Zones using KASP could not be thawed after they were
frozen using "rndc freeze". This has been fixed.
[GL #2523]
--- 9.16.13 released ---
5597. [bug] When serve-stale was enabled and starting the recursive
resolution process for a query failed, a named instance
could crash if it was configured as both a recursive and
authoritative server. This problem was introduced by
change 5573 and has now been fixed. [GL #2565]
5595. [cleanup] Public header files for BIND 9 libraries no longer
directly include third-party library headers. This
prevents the need to include paths to third-party header
files in CFLAGS whenever BIND 9 public header files are
used, which could cause build-time issues on hosts with
older versions of BIND 9 installed. [GL #2357]
5594. [bug] Building with --enable-dnsrps --enable-dnsrps-dl failed.
[GL #2298]
5593. [bug] Journal files written by older versions of named can now
be read when loading zones, so that journal
incompatibility does not cause problems on upgrade.
Outdated journals are updated to the new format after
loading. [GL #2505]
5592. [bug] Prevent hazard pointer table overflows on machines with
many cores, by allowing the thread IDs (serving as
indices into hazard pointer tables) of finished threads
to be reused by those created later. [GL #2396]
5591. [bug] Fix a crash that occurred when
"stale-answer-client-timeout" was triggered without any
(stale) data available in the cache to answer the query.
[GL #2503]
5590. [bug] NSEC3 records were not immediately created for dynamic
zones using NSEC3 with "dnssec-policy", resulting in
such zones going bogus. Add code to process the
NSEC3PARAM queue at zone load time so that NSEC3 records
for such zones are created immediately. [GL #2498]
5588. [func] Add a new "purge-keys" option for "dnssec-policy". This
option determines the period of time for which key files
are retained after they become obsolete. [GL #2408]
5586. [bug] An invalid direction field in a LOC record resulted in
an INSIST failure when a zone file containing such a
record was loaded. [GL #2499]
5584. [bug] No longer set the IP_DONTFRAG option on UDP sockets, to
prevent dropping outgoing packets exceeding
"max-udp-size". [GL #2466]
5582. [bug] BIND 9 failed to build when static OpenSSL libraries
were used and the pkg-config files for libssl and/or
libcrypto were unavailable. This has been fixed by
ensuring that the correct linking order for libssl and
libcrypto is always used. [GL #2402]
5581. [bug] Fix a memory leak that occurred when inline-signed zones
were added to the configuration, followed by a
reconfiguration of named. [GL #2041]
5580. [test] The system test framework no longer differentiates
between SKIPPED and UNTESTED system test results. Any
system test which is not run is now marked as SKIPPED.
[GL !4517]
5573. [func] When serve-stale is enabled and stale data is available,
named now returns stale answers upon encountering any
unexpected error in the query resolution process.
However, the "stale-refresh-time" window is still only
started upon a timeout. [GL #2434]
5564. [cleanup] Network manager's TLSDNS module was refactored to use
libuv and libssl directly instead of a stack of TCP/TLS
sockets. [GL #2335]
