[bsc#1221164] ------------------------------------------------------------------- Wed Feb 28 13:35:31 UTC 2024 - Pedro Monreal <pmonreal@suse.com> - Update to 1.19.1: * Bug Fixes: [bsc#1219823, CVE-2023-50387][bsc#1219826, CVE-2023-50868] - Fix CVE-2023-50387, DNSSEC verification complexity can be exploited to exhaust CPU resources and stall DNS resolvers. - Fix CVE-2023-50868, NSEC3 closest encloser proof can exhaust CPU. ------------------------------------------------------------------- Tue Feb 6 13:27:06 UTC 2024 - Stefan Seyfried <seife+obs@b1-systems.com> - as we use --disable-explicit-port-randomisation, also disable outgoing-port-permit and outgoing-port-avoid in config file to suppress the related unbound-checkconf warnings on every start ------------------------------------------------------------------- Fri Nov 17 09:50:18 UTC 2023 - Pedro Monreal <pmonreal@suse.com> - Update to 1.19.0: * Features: - Fix #850: [FR] Ability to use specific database in Redis, with new redis-logical-db configuration option. - Merge #944: Disable EDNS DO. Disable the EDNS DO flag in upstream requests. This can be helpful for devices that cannot handle DNSSEC information. But it should not be enabled otherwise, because that would stop DNSSEC validation. The DNSSEC validation would not work for Unbound itself, and also not for downstream users. Default is no. The option is disable-edns-do: no - Expose the script filename in the Python module environment 'mod_env' instead of the config_file structure which includes the linked list of scripts in a multi Python module setup; fixes #79. - Expose the configured listening and outgoing interfaces, if any, as a list of strings in the Python 'config_file' class instead of the current Swig object proxy; fixes #79. - Mailing list patches from Daniel Gröber for DNS64 fallback to plain AAAA when no A record exists for synthesis, and minor DNS64 code refactoring for better readability. - Merge #951: Cachedb no store. The cachedb-no-store: yes option is used to stop cachedb from writing messages to the backend storage. It reads messages when data is available from the backend. The default is no. * Bug Fixes: - Fix for version generation race condition that ignored changes. - Fix #942: 1.18.0 libunbound DNS regression when built without OpenSSL. - Fix for WKS call to getservbyname that creates allocation on exit in unit test by testing numbers first and testing from the services list later. - Fix autoconf 2.69 warnings in configure. - Fix #927: unbound 1.18.0 make test error. Fix make test without SHA1. - Merge #931: Prevent warnings from -Wmissing-prototypes. - Fix to scrub resource records of type A and AAAA that have an inappropriate size.

Reported by Florian Obser. - Fix authority zone answers for obscured DNAMEs and delegations. - Merge #936: Check for c99 with autoconf versions prior to 2.70. - Fix to remove two c99 notations. - Fix rpz tcp-only action with rpz triggers nsdname and nsip. - Fix misplaced comment. - Merge #881: Generalise the proxy protocol code. - Fix #946: Forwarder returns servfail on upstream response noerror no data. - Fix edns subnet so that queries with a source prefix of zero cause the recursor send no edns subnet option to the upstream. - Fix that printout of EDNS options shows the EDNS cookie option by name. - Fix infinite loop when reading multiple lines of input on a broken remote control socket. Addesses #947 and #948. - Fix #949: "could not create control compt". - Fix that cachedb does not warn when serve-expired is disabled about use of serve-expired-reply-ttl and serve-expired-client-timeout. - Fix for #949: Fix pythonmod/ubmodule-tst.py for Python 3.x. - Better fix for infinite loop when reading multiple lines of input on a broken remote control socket, by treating a zero byte line the same as transmission end. Addesses #947 and #948. - For multi Python module setups, clean previously parsed module functions in __main__'s dictionary, if any, so that only current module functions are registered. - Fix #954: Inconsistent RPZ handling for A record returned along with CNAME. - Fixes for the DNS64 patches. - Update the dns64_lookup.rpl test for the DNS64 fallback patch. - Merge #955 from buevsan: fix ipset wrong behavior. - Update testdata/ipset.tdir test for ipset fix. - Fix to print detailed errors when an SSL IO routine fails via SSL_get_error. - Clearer configure text for missing protobuf-c development libraries. - autoconf. - Merge #930 from Stuart Henderson: add void to log_ident_revert_to_default declaration. - Fix #941: dnscrypt doesn't work after upgrade to 1.18 with suggestion by dukeartem to also fix the udp_ancil with dnscrypt. - Fix SSL compile failure for definition in log_crypto_err_io_code_arg. - Fix SSL compile failure for other missing definitions in log_crypto_err_io_code_arg. - Fix compilation without openssl, remove unused function warning. - Mention flex and bison in README.md when building from repository source. ------------------------------------------------------------------- Thu Sep 7 08:03:33 UTC 2023 - Pedro Monreal <pmonreal@suse.com> - Update to 1.18.0: * Features: - Аdd a metric about the maximum number of collisions in lrushah. - Set max-udp-size default to 1232. This is the same default value as the default value for edns-buffer-size. It restricts client edns buffer size choices, and makes unbound behave similar to other DNS resolvers. - Add harden-unknown-additional option. It removes unknown records from the authority section and additional section. - Added new static zone type block_a to suppress all A queries for specific zones. - [FR] Ability to use Redis unix sockets. - [FR] Ability to set the Redis password. - Features/dropqueuedpackets, with sock-queue-timeout option that drops packets that have been in the socket queue for too long. Added statistics num.queries_timed_out and query.queue_time_us.max that track the socket queue timeouts. - 'eqvinox' Lamparter: NAT64 support. - [FR] Use kernel timestamps for dnstap. - Add cachedb hit stat. Introduces 'num.query.cachedb' as a new statistical counter. - Add SVCB dohpath support. - Add validation EDEs to queries where the CD bit is set. - Add prefetch support for subnet cache entries. - Add EDE (RFC8914) caching. - Add support for EDE caching in cachedb and subnetcache. - Downstream DNS Server Cookies a la RFC7873 and RFC9018. Create server cookies for clients that send client cookies. This needs to be explicitly turned on in the config file with: `answer-cookie: yes`. * Bug Fixes - Response change to NODATA for some ANY queries since 1.12. - Fix not following cleared RD flags potentially enables amplification DDoS attacks. - Set default for harden-unknown-additional to no. So that it does not hamper future protocol developments. - Fix to ignore entirely empty responses, and try at another authority. This turns completely empty responses, a type of noerror/nodata into a servfail, but they do not conform to RFC2308, and the retry can fetch improved content. - Allow TTL refresh of expired error responses. - Fix: Unexpected behavior with client-subnet-always-forward and serve-expired - Fix unbound-dnstap-socket test program to reply the finish frame over a TLS connection correctly. - Fix: reserved identifier violation - Fix: Unencrypted query is sent when forward-tls-upstream: yes is used without tls-cert-bundle - Extra consistency check to make sure that when TLS is requested, either we set up a TLS connection or we return an error. - Fix: NXDOMAIN instead of NOERROR rcode when asked for existing CNAME record. - Fix: Bad interaction with 0 TTL records and serve-expired - Fix RPZ IP responses with trigger rpz-drop on cache entries. - Fix RPZ removal of client-ip, nsip, nsdname triggers from IXFR. - Fix dereference of NULL variable warning in mesh_do_callback. - Fix ip_ratelimit test to work with dig that enables DNS cookies. - Fix for iter_dec_attempts that could cause a hang, part of capsforid and qname minimisation, depending on the settings. - Fix uninitialized memory passed in padding bytes of cmsg to sendmsg. - Fix stat_values test to work with dig that enables DNS cookies. - unbound.service: Main process exited, code=killed, status=11/SEGV. Fixes cachedb configuration handling. - Fix: processQueryResponse() THROWAWAY should be mindful of fail_reply. ------------------------------------------------------------------- Thu May 4 13:57:54 UTC 2023 - Frederic Crozat <fcrozat@suse.com> - Add _multibuild to define additional spec files as additional flavors.

Features: - Perform TLS SNI indication of the host that is being contacted for DNS over TLS service. It sets the configured tls auth name. This is useful for hosts that apart from the DNS over TLS services also provide other (web) services.

Features - unbound-control auth_zone_reload _zone_ option rereads the zonefile. - unbound-control auth_zone_transfer _zone_ option starts the probe sequence for a master to transfer the zone from and transfers when a new zone version is available. - num.queries.tls counter for queries over TLS. - log port number with err_addr logs. - dns64-ignore-aaaa: config option to list domain names for which the existing AAAA is ignored and dns64 processing is used on the A record. - Fix #4112: Fix that unbound-anchor -f /etc/resolv.conf will not pass if DNSSEC is not enabled. New option -R allows fallback from resolv.conf to direct queries. - Note RFC8162 support. SMIMEA record type can be read in by the zone record parser. - Patches from Jim Hague (Sinodun) for EDNS KeepAlive. - Add config tcp-idle-timeout (default 30s). This applies to client connections only; the timeout on TCP connections upstream is unaffected. - Add edns-tcp-keepalive and edns-tcp-keepalive timeout options and implement option in client responses. - Add delay parameter to streamtcp, -d secs. To be used when testing idle timeout. - Expose if a query (or a subquery) was ratelimited (not src IP ratelimiting) to libunbound under 'ub_result.was_ratelimited'. This also introduces a change to 'ub_event_callback_type' in libunbound/unbound-event.h. - Patch to implement tcp-connection-limit from Jim Hague (Sinodun). This limits the number of simultaneous TCP client connections from a nominated netblock. - Fix #4142: unbound.service.in: improvements and fixes. Add unit dependency ordering (based on systemd-resolved). Add 'CAP_SYS_RESOURCE' to 'CapabilityBoundingSet' (fixes warnings about missing privileges during startup). Add 'AF_INET6' to 'RestrictAddressFamilies' (without it IPV6 can't work). From Guido Shanahan. - unbound-checkconf checks if modules exist and prints if they are not compiled in the name of the wrong module. - Patch for stub-no-cache and forward-no-cache options that disable caching for the contents of that stub or forward, for when you want immediate changes visible, from Bjoern A. Zeeb. - Upgraded crosscompile script to include libunbound DLL in the zipfile. - Set libunbound to increase current, because the libunbound change to the event callback function signature. That needs programs, that use it, to recompile against the new header definition. - log-servfail: yes prints log lines that say why queries are returning SERVFAIL to clients. - log-local-actions: yes option for unbound.conf that logs all the local zone actions, a patch from Saksham Manchanda (Secure64). - #4146: num.query.subnet and num.query.subnet_cache counters. - #4140: Expose repinfo (comm_reply) to the inplace_callbacks. This gives access to reply information for the client's communication point when the callback is called before the mesh state (modules). Changes to C and Python's inplace_callback signatures were also necessary. - Set defaults to yes for a number of options to increase speed and resilience of the server. The so-reuseport, harden-below-nxdomain, and minimal-responses options are enabled by default. They used to be disabled by default, waiting to make sure they worked. They are enabled by default now, and can be disabled explicitly by setting them to "no" in the unbound.conf config file. The reuseport and minimal options increases speed of the server, and should be otherwise harmless. The harden-below-nxdomain option works well together with the recently default enabled qname minimisation, this causes more fetches to use information from the cache. - Added serve-expired-ttl and serve-expired-ttl-reset options. Bug Fixes - Windows example service.conf edited with more windows specific configuration. - #4108: systemd reload hang fix. - Fix usage printout for unbound-host, hostname has to be last argument on BSDs and Windows. - Partial fix for permission denied on IPv6 address on FreeBSD. - Fix that auth-zone master reply with current SOA serial does not stop scan of masters for an updated zone. - Fix that auth-zone does not start the wait timer without checking if the wait timer has already been started. - #4109: Fix that package config depends on python unconditionally. - Patch, do not export python from pkg-config, from Petr Menšík. - Fix checking for libhiredis printout in configure output. - Fix typo on man page in ip-address description. - Update libunbound/python/examples/dnssec_test.py example code to also set the 20326 trust anchor for the root in the example code. - Better documentation for unblock-lan-zones and insecure-lan-zones config statements. - Fix permission denied printed for auth zone probe random port nrs. - Fix documentation ambiguity for tls-win-cert in tls-upstream and forward-tls-upstream docs. - iana port update. - Fix round robin for failed addresses with prefer-ip6: yes - Note in documentation that the cert name match code needs OpenSSL 1.1.0 or later to be enabled. - Fix to improve systemd socket activation code file descriptor assignment. - Fix for 4126 that the #define for UNKNOWN_SERVER_NICENESS can be more easily changed to adjust default rtt assumptions. - Fix #4127 unbound -h does not list -p help. - Print error if SSL name verification configured but not available in the ssl library. - Fix that ratelimit and ip-ratelimit are applied after reload of changed config file. - Resize ratelimit and ip-ratelimit caches if changed on reload. - Fix #4129 unbound-control error message with wrong cert permissions is too cryptic. - Fix #4130: print text describing -dd and unbound-checkconf on config file read error at startup, the errors may have been moved away by the startup process. - Fix #4131: for solaris, error YY_CURRENT_BUFFER undeclared. - Fix use-systemd readiness signalling, only when use-systemd is yes and not in signal handler. - Fix #4135: 64-bit Windows Installer Creates Entries Under The Wrong Registry Key, reported by Brian White. - Fix man page, say that chroot is enabled by default. - Sort out test runs when the build directory isn't the project root directory. - Error if EDNS Keepalive received over UDP. - Correct and expand manual page entries for keepalive and idle timeout. - Implement progressive backoff of TCP idle/keepalive timeout. - Fix 'make depend' to work when build dir is not project root. - Fix #4139: Fix unbound-host leaks memory on ANY. - Fix to remove systemd sockaddr function check, that is not always present. Make socket activation more lenient. But not different when socket activation is not used. - Fix #4136: insufficiency from mismatch of FLEX capability between released tarball and build host. Fix to unconditionally call destroy in daemon.c. - Make capsforid fallback QNAME minimisation aware. - document --enable-subnet in doc/README. - Fix #4144: dns64 module caches wrong (negative) information. - Fix that printout of error for cycle targets is a verbosity 4 printout and does not wrongly print it is a memory error. - Fix segfault in auth-zone read and reorder of RRSIGs. - Fix contrib/fastrpz.patch. - Fix warning on compile without threads. - print servfail info to log as error. - added more servfail printout statements, to the iterator. - Fix classification for QTYPE=CNAME queries when QNAME minimisation is enabled. - Fix only misc failure from log-servfail when val-log-level is not enabled. - Fix lintflags for lint on FreeBSD. - Fix that a local-zone with a local-zone-type that is transparent in a view with view-first, makes queries check for answers from the local-zones defined outside of views. ------------------------------------------------------------------- Thu Jun 21 09:19:02 UTC 2018 - michael@stroeder.com - update to 1.7.3 Features - #4102 for NSD, but for Unbound. Named unix pipes do not use certificate and key files, access can be restricted with file and directory permissions. The option control-use-cert is no longer used, and ignored if found in unbound.conf. - Rename tls-additional-ports to tls-additional-port, because every line adds one port. Bug Fixes - Don't count CNAME response types received during qname minimisation as query restart. - #4100: Fix stub reprime when it becomes useless. - Fix crash if ratelimit taken into use with unbound-control instead of with unbound.conf. - Patch to fix openwrt for mac os build darwin detection in configure. - #4103: Fix that auth-zone does not insist on SOA record first in file for url downloads. - Fix that first control-interface determines if TLS is used.

This implementation depends on the hiredis client library (https://redislabs.com/lp/hiredis/). And unbound should be built with both --enable-cachedb and --with-libhiredis[=PATH] (where $PATH/include/hiredis/hiredis.h should exist). Patch from Jinmei Tatuya (Infoblox). - Create additional tls service interfaces by opening them on other portnumbers and listing the portnumbers as additional-tls-port: nr. - ED448 support. - num.query.authzone.up and num.query.authzone.down statistics counters. - Accept both option names with and without colon for get_option and set_option. - low-rtt and low-rtt-pct in unbound.conf enable the server selection of fast servers for some percentage of the time. - num.query.aggressive.NOERROR and num.query.aggressive.NXDOMAIN statistics counters. - allow-notify: config statement for auth-zones. - Can set tls authentication with forward-addr: IP#tls.auth.name And put the public cert bundle in tls-cert-bundle: "ca-bundle.pem". such as forward-addr: 9.9.9.9@853#dns.quad9.net or 1.1.1.1@853#cloudflare-dns.com - list_auth_zones unbound-control command. - Added root-key-sentinel support Bug Fixes - Fix #3727: Protocol name is TLS, options have been renamed but documentation is not consistent. - Check IXFR start serial. - Fix typo in documentation. - Fix #3736: Fix 0 TTL domains stuck on SERVFAIL unless manually flushed with serve-expired on. - Fix #3817: core dump happens in libunbound delete, when queued servfail hits deleted message queue. - corrected a minor typo in the changelog. - move htobe64/be64toh portability code to cachedb.c. - iana port update. - Do not use cached NSEC records to generate negative answers for domains under DNSSEC Negative Trust Anchors. - Fix unbound-control get_option aggressive-nsec - Check "result" in dup_all(), by Florian Obser. - Fix #4043: make test fails due to v6 presentation issue in macOS. - Fix unable to resolve after new WLAN connection, due to auth-zone failing with a forwarder set. Now, auth-zone is only used for answers (not referrals) when a forwarder is set. - Combine write of tcp length and tcp query for dns over tls. - nitpick fixes in example.conf. - Fix above stub queries for type NS and useless delegation point. - Fix unbound-control over pipe with openssl 1.1.1, the TLSv1.3 tls_choose_sigalg routine does not allow the ciphers for the pipe, so use TLSv1.2. - Fix that flush_zone sets prefetch ttl expired, so that with serve-expired enabled it'll start prefetching those entries. - Fix downstream auth zone, only fallback when auth zone fails to answer and fallback is enabled. - Fix for max include depth for authzones. - Fix memory free on fail for $INCLUDE in authzone. - Fix that an internal error to look up the wrong rr type for auth zone gets stopped, before trying to send there. - Fix auth zone target lookup iterator. - Fix auth-zone retry timer to be on schedule with retry timeout, with backoff. Also time a refresh at the zone expiry. - Fix #658: unbound using TLS in a forwarding configuration does not verify the server's certificate (RFC 8310 support). - For addr with #authname and no @port notation, the default is 853. - man page documentation for dns-over-tls forward-addr '#' notation. - removed free from failed parse case. - Fix #4091: Fix that reload of auth-zone does not merge the zonefile with the previous contents. - Delete auth zone when removed from config. - makedist uses bz2 for expat code, instead of tar.gz. - Fix #4092: libunbound: use-caps-for-id lacks colon in config_set_option. - auth zone http download stores exact copy of downloaded file, including comments in the file. - Fix sldns parse failure for CDS alternate delete syntax empty hex. - Attempt for auth zone fix; add of callback in mesh gets from callback does not skip callback of result. - Fix cname classification with qname minimisation enabled. - Fix contrib/fastrpz.patch for this release. - Fix auth https for libev. - Fix memory leak when caching wildcard records for aggressive NSEC use - Fix for crash in daemon_cleanup with dnstap during reload, from Saksham Manchanda. - Also that for dnscrypt. ------------------------------------------------------------------- Sun Apr 22 19:26:03 UTC 2018 - michael@stroeder.com - Commented configuration directive dlv-anchor-file: in unbound.conf (see bsc#1055060). The DLV key file is deliberately still shipped in the package so users could easily re-enable this. ------------------------------------------------------------------- Wed Apr 4 11:54:01 UTC 2018 - michael@stroeder.com - update to 1.7.0 Features - auth-zone provides a way to configure RFC7706 from unbound.conf, eg. with auth-zone: name: "." for-downstream: no for-upstream: yes fallback-enabled: yes and masters or a zonefile with data. - Aggressive use of NSEC implementation. Use cached NSEC records to generate NXDOMAIN, NODATA and positive wildcard answers. - Accept tls-upstream in unbound.conf, the ssl-upstream keyword is also recognized and means the same. Also for tls-port, tls-service-key, tls-service-pem, stub-tls-upstream and forward-tls-upstream. - [dnscrypt] introduce dnscrypt-provider-cert-rotated option, from Manu Bretelle. This option allows handling multiple cert/key pairs while only distributing some of them. In order to reliably match a client magic with a given key without strong assumption as to how those were generated, we need both key and cert. Likewise, in order to know which ES version should be used. On the other hand, when rotating a cert, it can be desirable to only serve the new cert but still be able to handle clients that are still using the old certs's public key. The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not publish the cert as part of the DNS's provider_name's TXT answer. - Update B root ipv4 address. - make ip-transparent option work on OpenBSD. - Fix #2801: Install libunbound.pc. - ltrace.conf file for libunbound in contrib. - Fix #3598: Fix swig build issue on rhel6 based system. configure --disable-swig-version-check stops the swig version check.

This makes the RDATA origin consistent between local-data and access-control-tag-data. * Fix NSEC ENT wildcard check. Matching wildcard does not have to be a subdomain of the NSEC owner. * QNAME minimisation uses QTYPE=A, therefore always check cache for this type in harden-below-nxdomain functionality. * Added unit test for QNAME minimisation + harden below nxdomain synergy. * Fix that with openssl 1.1 control-use-cert: no uses less cpu, by using no encryption over the unix socket. * hyphen as minus fix, by Andreas Schulze * Fix #1170: document that 'inform' local-zone uses local-data. * Fix #1173: differ local-zone type deny from unset tag_actions element. * Add DSA support for OpenSSL 1.1.0 * Fix remote control without cert for LibreSSL * Fix downcast warnings from visual studio in sldns code. ------------------------------------------------------------------- Tue Sep 27 12:41:57 UTC 2016 - michael@stroeder.com - update to 1.5.10 Features * Create a pkg-config file for libunbound in contrib. * TCP Fast open patch from Sara Dickinson. * Finegrained localzone control with define-tag, access-control-tag, access-control-tag-action, access-control-tag-data, local-zone-tag, and local-zone-override.

It ratelimits recursion effort per zone. For particular names you can configure exceptions in unbound.conf. - Ratelimit does not apply to prefetched queries, and ratelimit-factor is default 10. Repeated normal queries get resolved and with prefetch stay in the cache. - unbound-control ratelimit_list lists high rate domains. - caps-whitelist in unbound.conf allows whitelist of loadbalancers that cannot work with caps-for-id or its fallback. - RFC 7553 RR type URI support, is now enabled by default. - cache-max-negative-ttl config option, default 3600. - Add local-zone type inform_deny, that logs query and drops answer. Bug Fixes - Unbound exits with a fatal error when the auto-trust-anchor-file fails to be writable. This is seconds after startup. You can load a readonly auto-trust-anchor-file with trust-anchor-file. The file has to be writable to notice the trust anchor change, without it, a trust anchor change will be unnoticed and the system will then become inoperable. - DLV is going to be decommissioned. Advice to stop using it, and put text in the example configuration and man page to that effect. - Patch from Brad Smith that syncs compat/getentropy_linux with OpenBSD's version (2015-03-04). - 0x20 fallback improved: servfail responses do not count as missing comparisons (except if all responses are errors), inability to find nameservers does not fail equality comparisons, many nameservers does not try to compare more than max-sent-count, parse failures start 0x20 fallback procedure. - store caps_response with best response in case downgrade response happens to be the last one. - Document that incoming-num-tcp increase is good for large servers. - Fix lintian warning in unbound-checkconf man page (from Andreas Schulze). - Updated default keylength in unbound-control-setup to 3k. - Fixup compile on cygwin, more portable openssl thread id. - Use reallocarray for integer overflow protection, patch submitted by Loganaden Velvindron. - Fixed to add integer overflow checks on allocation (defense in depth). - Fix segfault on user not found at startup (from Maciej Soltysiak). - [bugzilla: 657 ] Fix that libunbound(3) recommends deprecated CRYPTO_set_id_callback. - If unknown trust anchor algorithm, and libressl is used, error message encourages upgrade of the libressl package. - rename ldns subdirectory to sldns to avoid name collision. - [bugzilla: 660 ] Fix interface-automatic broken in the presence of asymmetric routing. - Libunbound skips dos-line-endings from etc/hosts. - Fix crash in dnstap: Do not try to log TCP responses after timeout. - Fix that get_option for cache-sizes does not print double newline. - [bugzilla: 663 ] Fix that ssl handshake fails when using unix socket because dh size is too small. - [bugzilla: 664 ] libunbound python3 related fixes (from Tomas Hozza); Use print_function also for Python2. libunbound examples: produce sorted output. libunbound-Python: libldns is not used anymore.

TXT IN>: signature crypto failed from 2001:DB8:7:bba4::53 for <*.example.nl. NSEC IN> - Fix that unparseable error responses are ratelimited. - SOA negative TTL is capped at minimumttl in its rdata section. - [bugzilla: 674 ] Do not free pointers given by getenv. - [bugzilla: 677 ] Fix CNAME corresponding to a DNAME was checked incorrectly and was therefore always synthesized (thanks to Valentin Dietrich).

And remove ':' from output of stub and forward lists, this is easier to parse. - [bugzilla: 554] Fix use unsigned long to print 64bit statistics counters on 64bit systems. - [bugzilla: 558] Fix failed prefetch lookup does not remove cached response but delays next prefetch (in lieu of caching a SERVFAIL). - [bugzilla: 545] Fix improved logging, the ip address of the error is printed on the same log-line as the error. - [bugzilla: 502] Fix explain that do-ip6 disable does not stop AAAA lookups, but it stops the use of the ipv6 transport layer for DNS traffic. - Fix compile with libevent2 on FreeBSD. - Change MAX_SENT_COUNT from 16 to 32 to resolve some cases easier. - Fixup out-of-directory compile with unbound-control-setup.sh.in. - Code cleanup patch from Dag-Erling Smorgrav, with compiler issue fixes from FreeBSD's copy of Unbound, he notes: Generate unbound-control-setup.sh at build time so it respects prefix and sysconfdir from the configure script. Also fix the umask to match the comment, and the comment to match the umask. Add const and static where needed. Use unions instead of playing pointer poker. Move declarations that are needed in multiple source files into a shared header. Move sldns_bgetc() from parse.c to buffer.c where it belongs. Introduce a new header file, worker.h, which declares the callbacks that all workers must define. Remove those declarations from libworker.h. Include the correct headers in the correct places. Fix a few dummy callbacks that don't match their prototype. Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK. Remove a useless printf which breaks reproducible builds. Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're no longer used. Add unbound-control-setup.sh to the list of generated files. The prototype for libworker_event_done_cb() needs to be moved from libunbound/libworker.h to libunbound/worker.h. - Fix caps-for-id fallback, and added fallback attempt when servers drop 0x20 perturbed queries. - [bugzilla: 593] Fix segfault or crash upon rotating logfile. - fake-rfc2553 patch (thanks Benjamin Baier). - LibreSSL provides compat items, check for that in configure. - [bugzilla: 596] Bail out of unbound-control list_local_zones when ssl write fails. - Fix endian.h include for OpenBSD. - [bugzilla: 603] Fix unbound-checkconf -o option should skip verification checks. - Fixup doc/unbound.doxygen to remove obsolete 1.8.7 settings. - Update unbound manpage with more explanation (from Florian Obser). - Fix tcp timer waiting list removal code. - patches to also build with Python 3.x (from Pavel Simerda). - improve python configuration detection to build on Fedora 22. - Fix swig and python examples for Python 3.x. - Fix for mingw compile with openssl-1.0.1i. - [bugzilla: 612] Fix create service with service.conf in present directory and auto load it. - [bugzilla: 613] Allow tab ws in var length last rdfs (in ldns str2wire). - [bugzilla: 614] Fix man page variable substitution bug. - Whitespaces after $ORIGIN are not part of the origin dname (ldns). - $TTL's value starts at position 5 (ldns). - Fix unbound-checkconf check for module config with dns64 module. - Fix unbound capsforid fallback, it ignores TTLs in comparison. - [bugzilla: 617] Fix in ldns in unbound, lowercase WKS services. - Fix ctype invocation casts. - Disabled use of SSLv3 in remote-control and ssl-upstream. - Redefine internal minievent symbols to unique symbols that helps linking on platforms where the linker leaks names across modules. - Fix bug where forward or stub addresses with same address but different port number were not tried. ------------------------------------------------------------------- Mon Nov 10 00:45:00 UTC 2014 - Led <ledest@gmail.com> - fix bashisms in pre script ------------------------------------------------------------------- Fri Sep 5 13:32:55 UTC 2014 - darin@darins.net - cleanup .spec - removed unused packes ------------------------------------------------------------------- Tue Sep 2 13:21:55 UTC 2014 - darin@darins.net - disable %check until https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=602 is fixed ------------------------------------------------------------------- Wed Aug 20 13:34:00 UTC 2014 - darin@darins.net - Added firewall service file ------------------------------------------------------------------- Wed Aug 13 20:00:21 UTC 2014 - darin@darins.net - upadte to 1.4.22 - use /run for pid to clear dir-or-file-in-var-run in factory ------------------------------------------------------------------- Sat Dec 28 13:32:06 UTC 2013 - mrueckert@suse.de - fixed the execstartpre for unbound so we actually call unbound-anchor now. ------------------------------------------------------------------- Sat Dec 28 13:29:56 UTC 2013 - mrueckert@suse.de - fixed a few rpmlint warnings - added unbound-rpmlintrc: files duplicate on those man page links - changed symlink to /usr/sbin/service - improved descriptions ------------------------------------------------------------------- Sat Dec 28 04:02:56 UTC 2013 - mrueckert@suse.de - update to 1.4.21 merged lots of stuff from the fedora package - added python/munin/shlib/anchor subpackages - currently the package only supports systemd ------------------------------------------------------------------- Wed May 21 03:50:15 CEST 2008 - mrueckert@suse.de - initial package
