release-1.15.0
c29b0e0a · ·Unbound 1.15.0 This release has bug fixes for crashes that happened on heavy network usage. The default for the aggressive-nsec option has changed, it is now enabled. The ratelimit logic had to be reworked for the crash fixes. As a result, there are new options to control the behaviour of ratelimiting. The ratelimit-backoff and ip-ratelimit-backoff options can be used to control how severe the backoff is when the ratelimit is exceeded. The rpz-signal-nxdomain-ra option can be used to unset the RA flag, for NXDOMAIN answers from RPZ. That is used by some clients to detect that the domain is externally blocked. The RPZ option for-downstream can be used like for auth zones, this allows the RPZ zone information to be queried. That can be useful for monitoring scripts. Features - Fix #596: unset the RA bit when a query is blocked by an unbound RPZ nxdomain reply. The option rpz-signal-nxdomain-ra allows to signal that a domain is externally blocked to clients when it is blocked with NXDOMAIN by unsetting RA. - Add rpz: for-downstream: yesno option, where the RPZ zone is authoritatively answered for, so the RPZ zone contents can be checked with DNS queries directed at the RPZ zone. - Merge PR #616: Update ratelimit logic. It also introduces ratelimit-backoff and ip-ratelimit-backoff configuration options. - Change aggressive-nsec default to yes. Bug Fixes - Fix compile warning for if_nametoindex on windows 64bit. - Merge PR #581 from fobser: Fix -Wmissing-prototypes and -Wshadow warnings in rpz. - Fix validator debug output about DS support, print correct algorithm. - Add code similar to fix for ldns for tab between strings, for consistency, the test case was not broken. - Allow local-data for classes other than IN to inherit a configured local-zone's type if possible, instead of defaulting to type transparent as per the implicit rule. - Fix to pick up other class local zone information before unlock. - Add missing configure flags for optional features in the documentation. - Fix Unbound capitalization in the documentation. - Fix #591: Unbound-anchor manpage links to non-existent license file. - contrib/aaaa-filter-iterator.patch file renewed diff content to apply cleanly to the current coderepo for the current code version. - Fix to add test for rpz-signal-nxdomain-ra. - Fix #596: only unset RA when NXDOMAIN is signalled. - Fix that RPZ does not set RD flag on replies, it should be copied from the query. - Fix for #596: fix that rpz return message is returned and not just the rcode from the iterator return path. This fixes signal unset RA after a CNAME. - Fix unit tests for rpz now that the AA flag returns successfully from the iterator loop. - Fix for #596: add unit test for nsdname trigger and signal unset RA. - Fix for #596: add unit test for nsip trigger and signal unset RA. - Fix #598: Fix unbound-checkconf fatal error: module conf 'respip dns64 validator iterator' is not known to work. - Fix for #596: Fix rpz-signal-nxdomain-ra to work for clientip triggered operation. - Merge #600 from pemensik: Change file mode before changing file owner. - Fix prematurely terminated TCP queries when a reply has the same ID. - For #602: Allow the module-config "subnetcache validator cachedb iterator". - Fix EDNS to upstream where the same option could be attached more than once. - Add a region to serviced_query for allocations. - For dnstap, do not wakeupnow right there. Instead zero the timer to force the wakeup callback asap. - Fix #610: Undefine-shift in sldns_str2wire_hip_buf. - Fix #588: Unbound 1.13.2 crashes due to p->pc is NULL in serviced_udp_callback. - Merge PR #612: TCP race condition. - Test for NSID in SERVFAIL response due to DNSSEC bogus. - Fix #599: [FR] RFC 9156 (obsoletes RFC 7816), by noting the new RFC document. - Fix tls-* and ssl-* documented alternate syntax to also be available through remote-control and unbound-checkconf. - Better cleanup on failed DoT/DoH listening socket creation. - iana portlist update. - Fix review comment for use-after-free when failing to send UDP out. - Merge PR #603 from fobser: Use OpenSSL 1.1 API to access DSA and RSA internals. - Merge PR #532 from Shchelk: Fix: buffer overflow bug. - Merge PR #617: Update stub/forward-host notation to accept port and tls-auth-name. - Update stream_ssl.tdir test to also use the new forward-host notation. - Fix header comment for doxygen for authextstrtoaddr. - please clang analyzer for loop in test code. - Fix docker splint test to use more portable uname. - Update contrib/aaaa-filter-iterator.patch with diff for current software version. - Fix for #611: Integer overflow in sldns_wire2str_pkt_scan.

release-1.14.0
919c8c95 · ·Unbound 1.14.0 This release contains bug fixes and a full set of RPZ triggers and actions that are supported. This works with RPZ zones, configured with `rpz:`. It is possible to selectively enable use of TCP for stub zones and forward zones, without having enable it server wide, by enabling it with the `stub-tcp-upstream: yes` and `forward-tcp-upstream: yes` options. The added contrib/Dockerfile.tests from ziollek can be used to setup a Docker environment to run tests in. The documentation is in the doc/README.tests file. If openssl it installed with different versions, you can set the location as `--with-ssl=/usr/include/openssl11` and it then detects the use of the lib dir split off in /usr/lib64/openssl11 with regex. This is useful if to pass to configure if openssl is installed in such a manner. The option `outbound-msg-retry` can be used to select the number of retries when a non-positive response is received. It is best left at default, but when the upstream is known to not need retries, it can be lowered, because in that case the upstream is performing the retry for non-positive responses. The domain `home.arpa.` is set by default as blocked, as per RFC8375. If you want to use it, unblock it with a local-zone nodefault statement, or use another type of local-zone to override it with your choice. In the config it is possible to enter IPv6 scope-id values with interface names, instead of a number, for link-local addresses. Features - Merge #401: RPZ triggers. This add additional RPZ triggers, unbound supports a full set of rpz triggers, and this now includes nsdname, nsip and clientip triggers. Also actions are fully supported, and this now includes the tcp-only action. - Merge #519: Support for selective enabling tcp-upstream for stub/forward zones. - Merge PR #514, from ziollek: Docker environment for run tests. - Support using system-wide crypto policies. - Fix that --with-ssl can use "/usr/include/openssl11" to pass the location of a different openssl version. - Merged #41 from Moritz Schneider: made outbound-msg-retry configurable. - Implement RFC8375: Special-Use Domain 'home.arpa.'. - Merge PR #555 from fobser: Allow interface names as scope-id in IPv6 link-local addresses.

release-1.13.2
8e538dca · ·Unbound 1.13.2 This release contains a number of bug fixes. There is a crash fix for broken internal structures in stream reuse, that is used when many TCP or TLS upstream connections are made. Also a number of features are added. The ZONEMD support allows verification of downloaded authority zone files with the zonemd hash. It can be enabled with the zonemd-check option. It implements RFC8976. With zonemd-permissive-mode it is possible to try out the functionality without withholding the zone if the checks fail. With zonemd-reject-absence the zonemd record becomes a requirement for a zone. It is possible to use interface names for the control-interface as well, it was already possible for the interface, but now also for the remote control functionality. It allows the user to config the interface with the interface name, like 'eth0', instead of an IP address. It is possible to configure the persistent TCP connection, with the options max-reuse-tcp-queries and tcp-reuse-timeout. These also apply to TLS reused connections. The local zone types always_null, always_nodata and always_deny work inside the local zones that are defined inside a view. The log servfail error message now includes more information, it attempts to add an IP address and information about the one of the last failures that is associated with that query. With the option tcp-auth-query-timeout, the time to wait for queries to upstream authority servers can be configured, for TCP and TLS queries. It is possible to configure unbound with --with-deprecate-rsa-1024, that stops the use of RSA 1024 keys. That makes unbound work with certain FIPS installations that do not allow such calls to the crypto API. If the option is enabled, Unbound treats RSA keys with an insufficiently sized key as not supported. Responses with unsupported crypto are marked insecure. The NSEC3 maximum iterations are lowered to 150. This is the new default setting. This puts this in line with other DNS implementations. If the iterations count is exceeded the response becomes insecure. The number of validator retries when there is a DNSSEC failure can be configured with the val-max-restart option. The RR types SVCB and HTTPS are supported according to the draft specification. The syntax can be used in local zones and zone files, and debug output. The types themselves were already supported on the wire the RFC3597 unknown RR type support. The HTTP user agent header can be configured or elided, to avoid printing the version of type of the software running on the server, with the options http-user-agent and hide-http-user-agent. Features - Merge PR #317: ZONEMD Zone Verification, with RFC 8976 support. ZONEMD records are checked for zones loaded as auth-zone, with DNSSEC if available. There is an added option zonemd-permissive-mode that makes it log but not fail wrong zones. With zonemd-reject-absence for an auth-zone the presence of a zonemd can be mandated for specific zones. - Fix: Resolve interface names on control-interface too. - Merge #470 from edevil: Allow configuration of persistent TCP connections. - Fix #474: always_null and others inside view. - Add that log-servfail prints an IP address and more information about one of the last failures for that query. - Merge #478: Allow configuration of TCP timeout while waiting for response. - Add ./configure --with-deprecate-rsa-1024 that turns off RSA 1024. - Move the NSEC3 max iterations count in line with the 150 value used by BIND, Knot and PowerDNS. This sets the default value for it in the configuration to 150 for all key sizes. - zonemd-check: yesno option, default no, enables the processing of ZONEMD records for that zone. - Merge #486 by fobster: Make VAL_MAX_RESTART_COUNT configurable. - Merge PR #491: Add SVCB and HTTPS types and handling according to draft-ietf-dnsop-svcb-https. - Introduce 'http-user-agent:' and 'hide-http-user-agent:' options. Bug Fixes - Fix for Python 3.9, no longer use deprecated functions of PyEval_CallObject (now PyObject_Call), PyEval_InitThreads (now none), PyParser_SimpleParseFile (now Py_CompileString). - Merge PR #420 from dyunwei: DOH not responsing with "http2_query_read_done failure" logged. - Fix #422: IPv6 fallback issues when IPv6 is not properly enabled/configured. - Fix to make tests work with support indicators set for iterator. - Fix build on Python 3.10. - Fix doxygen and pydoc warnings. - Fix #429: rpz: url: with https: broken (regression in 1.13.1). - rpz skip nsec3param records, and nicer log for unsupported actions. - Fix #431: Squelch permission denied errors for tcp connect and udp connect from the logs, unless at high verbosity. - Fix for zonemd, that nxdomain for the chain of trust is allowed for island zones, it is treated as an insecure zone for verification. - Fix for zonemd, that domain-insecure zones work without dnssec. - Fix for zonemd, do not reject insecure result from trust anchor validation step in dnssec chain of trust. - On startup of unbound it checks if rlimits on memory size look sufficient for the configured cache size, and logs warning if not. - Fix function documentation. - Fix unit test for added ulimit checks. - spelling fix in header. - Fix #384: (1) A minor request to improve the log (2) A minor bug in one log message. - ipsecmod: Better logging for detecting a cycle when attaching the A/AAAA subquery. - Merge PR #367 : DNSTAP log local address.
