release-1.16.0
edc1d077 · ·Unbound 1.16.0 This release has EDE support, for extended EDNS error reporting, it fixes unsupported ZONEMD algorithms to load, and has more bug fixes. The EDE errors can be turned on by `ede: yes`, it is default disabled. Validation errors and other errors are then reported. If you also want stale answers for expired responses to have an error code, the option `ede-serve-expired: yes` can be used. Features - Merge PR #604: Add basic support for EDE (RFC8914). Bug Fixes - Fix #412: cache invalidation issue with CNAME+A. - Fix that TCP interface does not use TLS when TLS is also configured. - Fix #624: Unable to stop Unbound in Windows console (does not respond to CTRL+C command). - Fix #618: enabling interface-automatic disables DNS-over-TLS. Adds the option to list interface-automatic-ports. - Remove debug info from #618 fix. - Fix #628: A rpz-passthru action is not ending RPZ zone processing. - Fix for #628: fix rpz-passthru for qname trigger by localzone type. - Fix that address not available is squelched from the logs for udp connect failures. It is visible on verbosity 4 and more. - Merge #631 from mollyim: Replace OpenSSL's ERR_PACK with ERR_GET_REASON. - Fix to detect that no IPv6 support means that IPv6 addresses are useless for delegation point lookups. - update Makefile dependencies. - Fix check interface existence for support detection in remote lookup. - Fix #633: Document unix domain socket support for unbound-control. - Fix for #633: updated fix with new text. - Fix edns client subnet to add the option based on the option list, so that it is not state dependent, after the state fix of #605 for double EDNS options. - Fix for edns client subnet option add fix in removal code, from review. - Fix #630: Unify the RPZ log messages. - Merge #623 from rex4539: Fix typos. - Fix pythonmod for change in iter_dp_is_useless function prototype. - Fix compile warnings for printf ll format on mingw compile. - Merge PR #632 from scottrw93: Match cnames in ipset. - Various fixes for #632: variable initialisation, convert the qinfo to str once, accept trailing dot in the local-zone ipset option. - Fix #637: Integer Overflow in sldns_str2period function. - Fix for #637: fix integer overflow checks in sldns_str2period. - Fix configure for python to use sysutils, because distutils is deprecated. It uses sysutils when available, distutils otherwise. - Merge #644: Make `install-lib` make target install the pkg-config file. - Fix to ensure uniform handling of spaces and tabs when parsing RRs. - Fix to describe auth-zone and other configuration at the local-zone configuration option, to allow for more broadly view of the options. - Merge PR #648 from eaglegai: fix -q doesn't work when use with 'unbound-control stats_shm'. - Fix #651: [FR] Better logging for refused queries. - Fix spelling error in comment in sldns_str2wire_svcparam_key_lookup. - Fix zonemd check to allow unsupported algorithms to load.

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.

And fix python bindings, and test program unbound-dnstap-socket. - For #519: fix comments for doxygen. - Fix to print error from unbound-anchor for writing to the key file, also when not verbose. - For #514: generate configure. - Fix for #431: Squelch permission denied errors for udp connect, and udp send, they are visible at higher verbosity settings. - Fix zonemd verification of key that is not in DNS but in the zone and needs a chain of trust. - zonemd, fix order of bogus printout string manipulation. - Fix to support harden-algo-downgrade for ZONEMD dnssec checks. - Merge PR #528 from fobser: Make sldns_str2wire_svcparam_buf() static. - Fix #527: not sending quad9 cert to syslog (and may be more). - Fix sed script in ssldir split handling. - Fix #529: Fix: log_assert does nothing if UNBOUND_DEBUG is undefined. - Fix #531: Fix: passed to proc after free. - Fix #536: error: RPZ: name of record (drop.spamhaus.org.rpz.local.) to insert into RPZ. - Fix the stream wait stream_wait_count_lock and http2 buffer locks setup and desetup from race condition. - Fix RPZ locks. Do not unlock zones lock if requested and rpz find zone does not find the zone. Readlock the clientip that is found for ipbased triggers. Unlock the nsdname zone lock when done. Unlock zone and ip in rpz nsip and nsdname callback. Unlock authzone and localzone if clientip found in rpz worker call. - Fix compile warning in libunbound for listen desetup routine. - Fix asynclook unit test for setup of lockchecks before log. - Fix #533: Negative responses get cached even when setting cache-max-negative-ttl: 1 - Fix tcp fastopen failure when disabled, try normal connect instead. - Fix #538: Fix subnetcache statistics. - Small fixes for #41: changelog, conflicts resolved, processQueryResponse takes an iterator env argument like other functions in the iterator, no colon in string for set_option, and some whitespace style, to make it similar to the rest. - Fix for #41: change outbound retry to int to fix signed comparison warnings. - Fix root_anchor test to check with new icannbundle date. - Fix initialisation errors reported by gcc sanitizer. - Fix lock debug code for gcc sanitizer reports. - Fix more initialisation errors reported by gcc sanitizer. - Fix crosscompile on windows to work with openssl 3.0.0 the link with ws2_32 needs -l:libssp.a for __strcpy_chk.
