This is okay according 4035, but not after revising + existence in 4592. NSEC empty non-terminals exist and thus the + RCODE should have been NOERROR.

This ends up trying to acquire the lock again in + context_obtain_alloc in the call chain. + - Fix #528: if very high logging (4 or more) segfault on allow_snoop. + +26 Sep 2013: Wouter + - unbound-event.h is installed if configured --with-libevent. It + contains low-level library calls, that use libevent's event_base + and an ldns_buffer for the wire return packet to perform async + resolution in the client's eventloop. + +19 Sep 2013: Wouter + - 1.4.21 tag created. + - trunk has 1.4.22 number inside it. + - iana portlist updated. + - acx_nlnetlabs.m4 to 26; improve FLTO help text. + +16 Sep 2013: Wouter + - Fix#524: max-udp-size not effective to non-EDNS0 queries, from + Daisuke HIGASHI. + +10 Sep 2013: Wouter + - MIN_TTL and MAX_TTL also in time_t. + - tag 1.4.21rc1 made again. + +26 Aug 2013: Wouter + - More fixes for bug#519: for the threaded case test if the bg + thread has been killed, on ub_ctx_delete, to avoid hangs. + +22 Aug 2013: Wouter + - more fixes that I overlooked. + - review fixes from Willem. + +21 Aug 2013: Wouter + - Fix#520: Errors found by static analysis from Tomas Hozza(redhat). + +20 Aug 2013: Wouter + - Fix for 2038, with time_t instead of uint32_t. + +19 Aug 2013: Wouter + - Fix#519 ub_ctx_delete may hang in some scenarios (libunbound). + +14 Aug 2013: Wouter + - Fix uninit variable in fix#516. + +8 Aug 2013: Wouter + - Fix#516 dnssec lameness detection for answers that are improper. + +30 Jun 2013: Wouter + - tag 1.4.21rc1 + +29 Jun 2013: Wouter + - Fix#512 memleak in testcode for testbound (if it fails). + - Fix#512 NSS returned arrays out of setup function to be statics. + +26 Jun 2013: Wouter + - max include of 100.000 files (depth and globbed at one time). + This is to preserve system memory in bug cases, or endless cases. + - iana portlist updated. + +19 Jun 2013: Wouter + - streamtcp man page, contributed by Tomas Hozza. + - iana portlist updated. + - libunbound documentation on how to avoid openssl race conditions. + +25 Jun 2013: Wouter + - Squelch sendto-permission denied errors when the network is + not connected, to avoid spamming syslog. + - configure --disable-flto option (from Robert Edmonds). + +18 Jun 2013: Wouter + - Fix for const string literals in C++ for libunbound, from Karel + Slany. + - iana portlist updated. + +17 Jun 2013: Wouter + - Fixup manpage syntax. + +14 Jun 2013: Wouter + - get_option and set_option support for log-time-ascii, python-script + val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect + immediately.

Older fixes are + removed in place of a more exhaustive search for misconfigured data + available via the parent of a delegation. + This is designed to be throttled by cache entries, with TTL from the + parent if possible. Additionally the loop-counter is used. + It also tests for NS RRset differences between parent and child. + The fetch of misconfigured data should be more reliable and thorough. + It should work reliably even with no or only partial data in cache. + Data received from the child (as always) is deemed more + authoritative than information received from the delegation parent. + The search for misconfigured data is not performed normally. + +26 May 2010: Wouter + - Contribution from Migiel de Vos (Surfnet): nagios patch for + unbound-host, in contrib/ (in the source tarball).

If the iterator + can not recurse further and it finds the delegation in a state + where it would otherwise have rejected it outhand if so received + from a cache lookup, then it can try to ask higherup (with loop + protection). + - Fix comments in iter_utils:dp_is_useless. + +18 May 2010: Wouter + - Fix various compiler warnings from the clang llvm compiler. + - iana portlist updated. + +6 May 2010: Wouter + - Fix bug#308: spelling error in variable name in parser and lexer. + +4 May 2010: Wouter + - Fix dnssec-missing detection that was turned off by server selection. + - Conforms to draft-ietf-dnsop-default-local-zones-13.

When cycle + targets cause the server selection to believe there are more options + when they really are not there, the server selection is reinitiated. + - Fix fetch from blacklisted dnssec lame servers as last resort. The + server's IP address is then given in validator errors as well. + - Fix local-zone type redirect that did not use the query name for + the answer rrset. + +22 April 2010: Wouter + - tag 1.4.4. + - trunk contains 1.4.5 in development. + - Fix validation failure for qtype ANY caused by a RRSIG parse failure. + The validator error message was 'no signatures from ...'. + +16 April 2010: Wouter + - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN. + - tag 1.4.4rc1. + +15 April 2010: Wouter + - ECC-GOST algorithm number 12 that is assigned by IANA.

We made the choice to send out more conservatively, + protecting against an aggregate effect more than protecting a + single user (from their own folly, perhaps in case of misconfig). + +12 February 2010: Wouter + - Re-query pattern changed on validation failure. To protect troubled + authority servers, unbound caches a failure for the DNSKEY or DS + records for the entire zone, and only retries that 900 seconds later. + This implies that only a handful of packets are sent extra to the + authority if the zone fails. + +11 February 2010: Wouter + - ldns tarball update for long label length syntax error fix. + - iana portlist updated. + +9 February 2010: Wouter + - Fixup in compat snprintf routine, %f 1.02 and %g support. + - include math.h for testbound test compile portability. + +2 February 2010: Wouter + - Updated url of IANA itar, interim trust anchor repository, in script. + +1 February 2010: Wouter + - iana portlist updated. + - configure test for memcmp portability. + +27 January 2010: Wouter + - removed warning on format string in validator error log statement. + - iana portlist updated. + +22 January 2010: Wouter + - libtool finish the install of unbound python dynamic library. + +21 January 2010: Wouter + - acx_nlnetlabs.m4 synchronised with nsd's version. + +20 January 2010: Wouter + - Fixup lookup trouble for parent-child domains on the first query. + +14 January 2010: Wouter + - Fixup ldns detection to also check for header files. + +13 January 2010: Wouter + - prefetch-key option that performs DNSKEY queries earlier in the + validation process, and that could halve the latency on DNSSEC + queries.

The program uses wget and gpg to work. + - iana portlist updated. + - update-itar.sh: using ftp:// urls because https godaddy certificate + is not available everywhere and then gives fatal errors. The + security is provided by pgp signature. + +18 February 2009: Wouter + - more cycle detection. Also for target queries. + - fixup bug where during deletion of the mesh queries the callbacks + that were reentrant caused assertion failures. Keep the mesh in + a reentrant safe state.

And thus repeated validation helps + the operators get the problem fixed sooner. It makes validation + failures go away sooner (60 seconds after the zone is fixed). + Also it is likely to try different nameserver targets every minute, + so that if a zone is bad on one server but not another, it is + likely to pick up the 'correct' one after a couple minutes, + and if the TTL is big enough that solves validation for the zone. + - fixup unbound-control compilation on windows. + +17 October 2008: Wouter + - port Leopard/G5: fixup type conversion size_t/uint32. + please ranlib, stop file without symbols warning. + - harden referral path now also validates the root after priming. + It looks up the root NS authoritatively as well as the root servers + and attemps to validate the entries. + +16 October 2008: Wouter + - Fixup negative TTL values appearing (reported by Attila Nagy). + +15 October 2008: Wouter + - better documentation for 0x20; remove fallback TODO, it is done. + - harden-referral-path feature includes A, AAAA queries for glue, + as well as very careful NS caching (only when doing NS query). + A, AAAA use the delegation from the NS-query. + +14 October 2008: Wouter + - fwd_three.tpkg test was flaky. If the three requests hit the + wrong threads by chance (or bad OS) then the test would fail. + Made less flaky by increasing number of retries. + - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs. + - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014). + Which includes the ldns_dname_absolute fix. + - fwd_three test remains flaky now that unbound does not stop + listening when full.

Added a test for it. + - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com" + +29 September 2008: Wouter + - EDNS lameness detection, if EDNS packets are dropped this is + detected, eventually. + - multiple query timeout rtt backoff does not backoff too much. + +26 September 2008: Wouter + - tests for remote-control. + - small memory leak in exception during remote control fixed. + - fixup for lock checking but not unchecking in remote control. + - iana portlist updated. + +23 September 2008: Wouter + - Msg cache is loaded.

Also works on Solaris 10 sparc64, + Solaris 9, FreeBSD 6, Linux i386 and OSX powerpc. + - malloc rndstate, so that it is aligned for access. + - fixed rbtree cleanup with postorder traverse. + - fixed pending messages are deleted when handled. + - You can control verbosity; default is not verbose, every -v + adds more verbosity. + +14 February 2007: Wouter + - Included configure.ac changes from ldns. + - detect (some) headers before the standards check. + - do not use isblank to test c99, since its not available on solaris9. + - review of testcode. + * entries in a RANGE are no longer reversed. + * print name of file with replay entry parse errors. + - port to OSX: cast to int for some prints of sizet. + - Makefile copies ldnstestpkts.c before doing dependencies on it. + +13 February 2007: Wouter + - work on fake events, first fwd replay works. + - events can do timeouts and errors on queries to servers. + - test package that runs replay scenarios. + +12 February 2007: Wouter + - work on fake events. + +9 February 2007: Wouter + - replay file reading. + - fake event setup, it creates fake structures, and teardowns, + added signal callbacks to reply to be able to fake those, + and main structure of event replay routines. + +8 February 2007: Wouter + - added tcp test. + - replay storage. + - testcode/fake_event work. + +7 February 2007: Wouter + - return answer with the same ID as query was sent with. + - created udp forwarder test. I've done some effort to make it perform + quickly. After servers are created, no big sleep statements but + it checks the logfiles to see if servers have come up. Takes 0.14s. + - set addrlen value when calling recvfrom. + - comparison of addrs more portable. + - LIBEVENT option for testbed to set libevent directory. + - work on tcp input. + +6 February 2007: Wouter + - reviewed code and improved in places. + +5 February 2007: Wouter + - Picked up stdc99 and other define tests from ldns. Improved + POSIX define test to include getaddrinfo. + - defined constants for netevent callback error code. + - unit test for strisip6. + +2 February 2007: Wouter + - Created udp4 and udp6 port arrays to provide service for both + address families. + - uses IPV6_USE_MIN_MTU for udp6 ,IPV6_V6ONLY to make ip6 sockets. + - listens on both ip4 and ip6 ports to provide correct return address. + - worker fwder address filled correctly. + - fixup timer code. + - forwards udp queries and sends answer. + +1 February 2007: Wouter + - outside network more UDP work. + - moved * closer to type. + - comm_timer object and events. + +31 January 2007: Wouter + - Added makedist.sh script to make release tarball. + - Removed listen callback layer, did not add anything. + - Added UDP recv to netevent, worker callback for udp. + - netevent communication reply storage structure. + - minimal query header sanity checking for worker. + - copied over rbtree implementation from NSD (BSD licensed too). + - outgoing network query service work. + +30 January 2007: Wouter + - links in example/ldns-testpkts.c and .h for premade packet support. + - added callback argument to listen_dnsport and daemon/worker. + +29 January 2007: Wouter + - unbound.8 a short manpage. + +26 January 2007: Wouter + - fixed memleak. + - make lint works on BSD and Linux (openssl defines). + - make tags works. + - testbound program start. + +25 January 2007: Wouter + - fixed lint so it may work on BSD. + - put license into header of every file. + - created verbosity flag. + - fixed libevent configure flag. + - detects event_base_free() in new libevent 1.2 version. + - getopt in daemon. fatal_exit() and verbose() logging funcs. + - created log_assert, that throws assertions to the logfile. + - listen_dnsport service. Binds ports. + +24 January 2007: Wouter + - cleaned up configure.ac. + +23 January 2007: Wouter + - added libevent to configure to link with. + - util/netevent setup work. + - configure searches for libevent. + - search for libs at end of configure (when other headers and types + have been found). + - doxygen works with ATTR_UNUSED(). + - util/netevent implementation. + +22 January 2007: Wouter + - Designed header file for network communication. + +16 January 2007: Wouter + - added readme.svn and readme.tests. + +4 January 2007: Wouter + - Testbed script (run on multiple platforms the test set). + Works on Sunos9, Sunos10, FreeBSD 6.1, Fedora core 5. + - added unit test tpkg. + +3 January 2007: Wouter + - committed first set of files into subversion repository. + svn co svn+ssh://unbound.net/svn/unbound + You need a ssh login. There is no https access yet. + - Added LICENSE, the BSD license. + - Added doc/README with compile help. + - main program stub and quiet makefile. + - minimal logging service (to stderr). + - added postcommit hook that serves emails. + - added first test 00-lint. postcommit also checks if build succeeds. + - 01-doc: doxygen doc target added for html docs.
