1420 for secure domain name system traffic.
1421 If you used to rely on the older default of port 443, you have
1422 to put a clause in unbound.conf for that. The new value is likely
1423 going to be the standardised port number for this traffic.

1553 put text in the example configuration and man page to that effect.
1556 - Change syntax of particular validator error to be easier for
1557 machine parse, swap rrset and ip adres info so it looks like:
1558 validation failure <www.example.nl. TXT IN>: signature crypto
1559 failed from 2001:DB8:7:bba4::53 for <*.example.nl. NSEC IN>
1562 - caps-whitelist in unbound.conf allows whitelist of loadbalancers

1601 7 April 2015: Wouter
1602 - Libunbound skips dos-line-endings from etc/hosts.
1603 - Unbound exits with a fatal error when the auto-trust-anchor-file
1604 fails to be writable. This is seconds after startup. You can
1605 load a readonly auto-trust-anchor-file with trust-anchor-file.
1606 The file has to be writable to notice the trust anchor change,
1607 without it, a trust anchor change will be unnoticed and the system
1608 will then become inoperable.
1609 - unbound-control list_insecure command shows the negative trust
1610 anchors currently configured, patch from Jelte Jansen.

1665 - Patch from Brad Smith that syncs compat/getentropy_linux with
1666 OpenBSD's version (2015-03-04).
1667 - 0x20 fallback improved: servfail responses do not count as missing
1668 comparisons (except if all responses are errors),
1669 inability to find nameservers does not fail equality comparisons,
1670 many nameservers does not try to compare more than max-sent-count,
1671 parse failures start 0x20 fallback procedure.
1672 - store caps_response with best response in case downgrade response
1673 happens to be the last one.
1674 - Document windows 8 tests.

2032 - Code cleanup patch from Dag-Erling Smorgrav, with compiler issue
2033 fixes from FreeBSD's copy of Unbound, he notes:
2034 Generate unbound-control-setup.sh at build time so it respects
2035 prefix and sysconfdir from the configure script. Also fix the
2036 umask to match the comment, and the comment to match the umask.
2037 Add const and static where needed. Use unions instead of
2038 playing pointer poker. Move declarations that are needed in
2039 multiple source files into a shared header. Move sldns_bgetc()
2040 from parse.c to buffer.c where it belongs. Introduce a new
2041 header file, worker.h, which declares the callbacks that
2042 all workers must define. Remove those declarations from
2043 libworker.h. Include the correct headers in the correct places.
2044 Fix a few dummy callbacks that don't match their prototype.

2048 no longer used. Add unbound-control-setup.sh to the list of
2049 generated files. The prototype for libworker_event_done_cb()

2061 perform 10.0.0.0/8 and other reverse lookups normally, for use if
2062 unbound is running service for localhost on localhost.
2065 - Updated create_unbound_ad_servers and unbound_cache scripts from
2066 Yuri Voinov in the source/contrib directory. Added
2067 warmup.cmd (and .sh): warm up the DNS cache with your MRU domains.
2070 - Implement draft-ietf-dnsop-rfc6598-rfc6303-01.
2071 - iana portlist updated.
2074 - Contrib windows scripts from Yuri Voinov added to src/contrib:
2075 create_unbound_ad_servers.cmd: enters anti-ad server lists.
2076 unbound_cache.cmd: saves and loads the cache.
2077 - Added unbound-control-setup.cmd from Yuri Voinov to the windows
2078 unbound distribution set. It requires openssl installed in %PATH%.
2081 - Change MAX_SENT_COUNT from 16 to 32 to resolve some cases easier.

2090 and errors from the cache. For dnssec-trigger and NetworkManager,
2091 fixes cases where network changes have localdata that was already
2092 negatively cached from the previous network.
2094 23 April 2014: Wouter
2095 - Patch from Jeremie Courreges-Anglas to use arc4random_uniform
2096 if available on the OS, it gets entropy from the OS.
2098 15 April 2014: Wouter
2099 - Fix compile with libevent2 on FreeBSD.
2101 11 April 2014: Wouter
2102 - Fix #502: explain that do-ip6 disable does not stop AAAA lookups,

2104 - iana portlist updated.
2106 10 April 2014: Wouter
2107 - iana portlist updated.
2108 - Patch from Hannes Frederic Sowa for Linux 3.15 fragmentation

2114 +i annotation in output of list_forwards, also for list_stubs
2115 (for NetworkManager integration.)
2116 - Fix #554: use unsigned long to print 64bit statistics counters on
2118 - Fix #558: failed prefetch lookup does not remove cached response
2119 but delays next prefetch (in lieu of caching a SERVFAIL).
2120 - Fix #545: improved logging, the ip address of the error is printed
2121 on the same log-line as the error.
2123 8 April 2014: Wouter
2124 - Fix #574: make test fails on Ubuntu 14.04. Disabled remote-control
2125 in testbound scripts.
2126 - iana portlist updated.
2128 7 April 2014: Wouter
2129 - C.ROOT-SERVERS.NET has an IPv6 address, and we updated the root
2130 hints (patch from Anand Buddhdev).
2131 - Fix #572: Fix unit test failure for systems with different
2134 28 March 2014: Wouter
2135 - Fix #569: do_tcp is do-tcp in unbound.conf man page.

2154 21 February 2014: Wouter
2155 - iana portlist updated.
2157 20 February 2014: Matthijs
2158 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
2159 received. This is okay according 4035, but not after revising
2160 existence in 4592. NSEC empty non-terminals exist and thus the
2161 RCODE should have been NOERROR. If this occurs, and the RRsets
2162 are secure, we set the RCODE to NOERROR and the security status
2163 of the response is also considered secure.
2165 14 February 2014: Wouter
2166 - Works on Minix (3.2.1).
2168 11 February 2014: Wouter

2194 - fixup nss compile (no ldns in it).
2195 - fixup warning in unitldns
2196 - fixup WKS and rdata type service to print unsigned because strings
2197 are not portable; they cannot be read (for sure) on other computers.
2198 - fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
2201 30 January 2014: Wouter
2202 - delay-close does not act if there are udp-wait queries, so that
2203 it does not make a socketdrain DoS easier.
2205 28 January 2014: Wouter
2206 - iana portlist updated.
2207 - iana portlist test updated so it does not touch the source
2208 if there are no changes.
2209 - delay-close: msec option that delays closing ports for which
2210 the UDP reply has timed out. Keeps the port open, only accepts
2211 the correct reply. This correct reply is not used, but the port
2212 is open so that no port-denied ICMPs are generated.
2214 27 January 2014: Wouter
2215 - reuseport is attempted, then fallback to without on failure.
2217 24 January 2014: Wouter
2218 - Change unbound-event.h to use void* buffer, length idiom.
2219 - iana portlist updated.
2220 - unbound-event.h is installed if you configure --enable-event-api.
2221 - speed up unbound (reports say it could be up to 10%), by reducing
2222 lock contention on localzones.lock. It is changed to an rwlock.
2223 - so-reuseport: yesno option to distribute queries evenly over
2224 threads on Linux (Thanks Robert Edmonds).
2227 21 January 2014: Wouter
2228 - Fix #547: no trustanchor written if filesystem full, fclose checked.
2230 17 January 2014: Wouter
2231 - Fix isprint() portability in sldns, uses unsigned int.
2232 - iana portlist updated.
2234 16 January 2014: Wouter
2235 - fix #544: Fixed +i causes segfault when running with module conf
2237 - Windows port, adjust %lld to %I64d, and warning in win_event.c.
2239 14 January 2014: Wouter
2240 - iana portlist updated.
2243 - Fix bug in cachedump that uses sldns.
2244 - update pythonmod for ldns_ to sldns_ name change.
2247 - Fix sldns to use sldns_ prefix for all ldns_ variables.
2248 - Fix windows compile to compile with sldns.
2251 - Fix sldns to make globals use sldns_ prefix. This fixes
2252 linking with libldns that uses global variables ldns_ .
2255 - Fix bug#537: compile python plugin without ldns library.
2258 - Fix bug#536: acl_deny_non_local and refuse_non_local added.
2261 - Patch from Neel Goyal to fix async id assignment if callback
2262 is called by libunbound in the mesh attach.
2263 - Accept ip-address: as an alternative for interface: for
2264 consistency with nsd.conf syntax.
2267 - Patch from Neel Goyal to fix callback in libunbound.
2270 - if configured --with-libunbound-only fix make install.
2273 - Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
2274 more specific interface port 53 can be used at the same time, and
2275 one of the daemons is unbound.
2276 - iana portlist update.
2277 - separate ldns into core ldns inside ldns/ subdirectory. No more
2278 --with-ldns is needed and unbound does not rely on libldns.
2279 - portability fixes for new USE_SLDNS ldns subdir codebase.
2282 - Patch from Neel Goyal: Add an API call to set an event base on an
2283 existing ub_ctx. This basically just destroys the current worker and
2284 sets the event base to the current. And fix a deadlock in
2285 ub_resolve_event – the cfglock is held when libworker_create is
2286 called. This ends up trying to acquire the lock again in
2287 context_obtain_alloc in the call chain.
2288 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
2291 - unbound-event.h is installed if configured --with-libevent. It
2292 contains low-level library calls, that use libevent's event_base
2293 and an ldns_buffer for the wire return packet to perform async
2294 resolution in the client's eventloop.
2297 - 1.4.21 tag created.
2298 - trunk has 1.4.22 number inside it.
2299 - iana portlist updated.
2300 - acx_nlnetlabs.m4 to 26; improve FLTO help text.
2303 - Fix#524: max-udp-size not effective to non-EDNS0 queries, from
2307 - MIN_TTL and MAX_TTL also in time_t.
2308 - tag 1.4.21rc1 made again.
2311 - More fixes for bug#519: for the threaded case test if the bg
2312 thread has been killed, on ub_ctx_delete, to avoid hangs.
2315 - more fixes that I overlooked.
2316 - review fixes from Willem.
2319 - Fix#520: Errors found by static analysis from Tomas Hozza(redhat).
2322 - Fix for 2038, with time_t instead of uint32_t.
2325 - Fix#519 ub_ctx_delete may hang in some scenarios (libunbound).
2328 - Fix uninit variable in fix#516.
2331 - Fix#516 dnssec lameness detection for answers that are improper.
2337 - Fix#512 memleak in testcode for testbound (if it fails).
2338 - Fix#512 NSS returned arrays out of setup function to be statics.
2341 - max include of 100.000 files (depth and globbed at one time).
2342 This is to preserve system memory in bug cases, or endless cases.

2346 - streamtcp man page, contributed by Tomas Hozza.
2347 - iana portlist updated.
2348 - libunbound documentation on how to avoid openssl race conditions.

2356 - Fix for const string literals in C++ for libunbound, from Karel
2358 - iana portlist updated.
2361 - Fixup manpage syntax.
2364 - get_option and set_option support for log-time-ascii, python-script
2365 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
2366 immediately. The others are mostly useful for libunbound users.
2369 - get_option, set_option, unbound-checkconf -o and libunbound
2370 getoption and setoption support cache-min-ttl and cache-max-ttl.
2373 - Fix#501: forward-first does not recurse, when forward name is ".".
2374 - iana portlist update.
2375 - Max include depth is unlimited.
2378 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply
2379 patch to it to not fail when -Werror is also specified, from the
2381 - iana portlist update.
2384 - Explain bogus and secure flags in libunbound more.
2387 - Fix#499 use-after-free in out-of-memory handling code (thanks Jake
2389 - Fix#500 use on non-initialised values on socket bind failures.
2392 - Fix round-robin doesn't work with some Windows clients (from Ilya

2987 - fix iana_update target for gzipped file on iana site.
2989 24 October 2011: Wouter
2990 - Fix resolve of partners.extranet.microsoft.com with a fix for the
2991 server selection for choosing out of a (particular) list of bad
2993 - Fix make_new_space function so that the incoming query is not
2994 overwritten if a jostled out query causes a waiting query to be
2995 resumed that then fails and sends an error message. (Thanks to
2998 21 October 2011: Wouter
2999 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
3000 option enabled because of memory layout exe vs dll.
3002 19 October 2011: Wouter
3003 - fix unbound-anchor for broken strptime on OSX lion, detected
3005 - Detect if GOST really works, openssl1.0 on OSX fails.
3006 - Implement ipv6%interface notation for scope_id usage.
3008 17 October 2011: Wouter
3009 - better documentation for inform_super (Thanks Yang Zhe).
3011 14 October 2011: Wouter
3012 - Fix for out-of-memory condition in libunbound (thanks
3015 13 October 2011: Wouter
3016 - Fix --enable-allsymbols, it depended on link specifics of the
3017 target platform, or fptr_wlist assertion failures could occur.
3019 12 October 2011: Wouter
3020 - updated contrib/unbound_munin_ to family=auto so that it works with
3021 munin-node-configure automatically (if installed as
3022 /usr/local/share/munin/plugins/unbound_munin_ ).
3024 27 September 2011: Wouter
3025 - unbound.exe -w windows option for start and stop service.
3027 23 September 2011: Wouter
3028 - TCP-upstream calculates tcp-ping so server selection works if there
3031 20 September 2011: Wouter
3032 - Fix classification of NS set in answer section, where there is a
3033 parent-child server, and the answer has the AA flag for dir.slb.com.
3034 Thanks to Amanda Constant from Secure64.
3036 16 September 2011: Wouter
3037 - fix bug #408: accept patch from Steve Snyder that comments out
3038 unused functions in lookup3.c.
3039 - iana portlist updated.
3040 - fix EDNS1480 change memleak and TCP fallback.
3041 - fix various compiler warnings (reported by Paul Wouters).
3042 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
3043 fetch if sentcount > 3, stop query if sentcount > 16. Count is
3044 reset when referral or CNAME happens. This makes unbound better
3045 at managing large NS sets, they are explored when there is continued
3046 interest (in the form of queries).
3048 15 September 2011: Wouter
3050 - trunk contains 1.4.14 in development.
3051 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
3053 12 September 2011: Wouter
3054 - Reverted dns EDNS backoff fix, it did not help and needs
3055 fragmentation fixes instead.
3058 7 September 2011: Wouter
3059 - Fix operation in ipv6 only (do-ip4: no) mode.
3061 6 September 2011: Wouter
3062 - fedora specfile updated.
3064 5 September 2011: Wouter
3067 2 September 2011: Wouter
3068 - iana portlist updated.
3070 26 August 2011: Wouter
3071 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
3072 - Fix validation failures due to EDNS backoff retries, the retry
3073 for fetch of data has want_dnssec because the iter_indicate_dnssec
3074 function returns true when validation failure retry happens, and
3075 then the serviced query code does not fallback to noEDNS, even if
3076 the cache says it has this. This helps for DLV deployment when
3077 the DNSSEC status is not known for sure before the lookup concludes.
3079 24 August 2011: Wouter
3080 - Applied patch from Karel Slany that fixes a memory leak in the
3081 unbound python module, in string conversions.
3083 22 August 2011: Wouter
3084 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
3085 Zhang and Luo Ce). Unbound responds with the RR types that are
3086 available at the name for qtype ANY and validates those RR types.
3087 It does not test for completeness (i.e. with NSEC or NSEC3 query),
3088 and it does not follow the CNAME or DNAME to another name (with
3089 even more data for the already large response).
3090 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
3091 - Documented the options that work with control set_option command.
3092 - tcp-upstream yes/no option (works with set_option) for tunnels.
3094 18 August 2011: Wouter
3095 - fix autoconf call in makedist crosscompile to RC or snapshot.
3097 17 August 2011: Wouter
3098 - Fix validation of . DS query.

3100 - iana portlist updated.
3102 10 August 2011: Wouter
3103 - Fix python site-packages path to /usr/lib64.
3104 - updated patch from Tom.
3105 - fix memory and fd leak after out-of-memory condition.
3107 9 August 2011: Wouter
3108 - patch from Tom Hendrikx fixes load of python modules.
3110 8 August 2011: Wouter
3111 - make clean had ldns-src reference, removed.
3113 1 August 2011: Wouter
3114 - Fix autoconf 2.68 warnings
3116 14 July 2011: Wouter
3117 - Unbound implements RFC6303 (since version 1.4.7).
3118 - tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
3119 meantime, those are for 1.4.13).
3120 - iana portlist updated.
3122 13 July 2011: Wouter
3123 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
3125 11 July 2011: Wouter
3126 - Fix wildcard expansion no-data reply under an optout NSEC3 zone is
3127 validated as insecure, reported by Jia Li (lijia@cnnic.cn).
3130 - 1.4.12rc1 tag created.
3133 - version number in example config file.
3134 - fix that --enable-static-exe does not complain about it unknown.
3136 30 June 2011: Wouter
3137 - tag relase 1.4.11, trunk is 1.4.12 development.
3138 - iana portlist updated.
3139 - fix bug#395: id bits of other query may leak out under conditions
3140 - fix replyaddr count wrong after jostled queries, which leads to
3141 eventual starvation where the daemon has no replyaddrs left to use.
3142 - fix comment about rndc port, that referred to the old port number.
3143 - fix that the listening socket is not closed when too many remote
3144 control connections are made at the same time.
3145 - removed ldns-src tarball inside the unbound tarball.
3147 23 June 2011: Wouter
3148 - Changed -flto check to support clang compiler.
3149 - tag 1.4.11rc3 created.
3151 17 June 2011: Wouter
3152 - tag 1.4.11rc1 created.
3153 - remove warning about signed/unsigned from flex (other flex version).
3154 - updated aclocal.m4 and libtool to match.
3155 - tag 1.4.11rc2 created.
3157 16 June 2011: Wouter
3158 - log-queries: yesno option, default is no, prints querylog.
3159 - version is 1.4.11.
3161 14 June 2011: Wouter
3162 - Use -flto compiler flag for link time optimization, if supported.
3163 - iana portlist updated.
3165 12 June 2011: Wouter
3166 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
3168 10 June 2011: Wouter
3169 - unbound-control has version number in the header,
3170 UBCT[version]_space_ is the header sent by the client now.
3171 - Unbound control port number is registered with IANA:
3172 ub-dns-control 8953/tcp unbound dns nameserver control
3173 This is the new default for the control-port config setting.
3174 - statistics-interval prints the number of jostled queries to log.
3177 - Fix Makefile for U in environment, since wrong U is more common than
3178 deansification necessity.
3179 - iana portlist updated.
3180 - updated ldns tarball to 1.6.10rc2 snapshot of today.
3183 - Fix assertion failure when unbound generates an empty error reply
3184 in response to a query, CVE-2011-1922 VU#531342.
3185 - This fix is in tag 1.4.10.
3186 - defense in depth against the above bug, an error is printed to log
3187 instead of an assertion failure.
3190 - bug#386: --enable-allsymbols option links all binaries to libunbound
3191 and reduces install size significantly.
3192 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
3193 - iana portlist updated.
3194 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
3196 14 April 2011: Wouter
3197 - configure created with newer autoconf 2.66.
3199 12 April 2011: Wouter
3200 - bug#378: Fix that configure checks for ldns_get_random presence.
3202 8 April 2011: Wouter
3203 - iana portlist updated.
3204 - queries with CD flag set cause DNSSEC validation, but the answer is
3205 not withheld if it is bogus. Thus, unbound will retry if it is bad
3206 and curb the TTL if it is bad, thus protecting the cache for use by
3207 downstream validators.
3208 - val-override-date: -1 ignores dates entirely, for NTP usage.
3210 29 March 2011: Wouter
3211 - harden-below-nxdomain: changed so that it activates when the
3212 cached nxdomain is dnssec secure. This avoids backwards
3213 incompatibility because those old servers do not have dnssec.
3215 24 March 2011: Wouter
3216 - iana portlist updated.
3220 17 March 2011: Wouter
3221 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
3222 Applied but did not do the --disable-gost.
3224 10 March 2011: Wouter
3225 - tag 1.4.9 release candidate 1 created.
3227 3 March 2011: Wouter
3228 - updated ldns to today.
3230 1 March 2011: Wouter
3231 - Fix no ADflag for NXDOMAIN in NSEC3 optout. And wildcard in optout.
3232 - give config parse error for multiple names on a stub or forward zone.
3233 - updated ldns tarball to 1.6.9(todays snapshot).
3235 24 February 2011: Wouter
3236 - bug #361: Fix, time.elapsed variable not reset with stats_noreset.
3238 23 February 2011: Wouter
3239 - iana portlist updated.
3240 - common.sh to version 3.
3242 18 February 2011: Wouter
3243 - common.sh in testdata updated to version 2.
3245 15 February 2011: Wouter
3246 - Added explicit note on unbound-anchor usage:
3247 Please note usage of unbound-anchor root anchor is at your own risk
3248 and under the terms of our LICENSE (see that file in the source).
3250 11 February 2011: Wouter
3251 - iana portlist updated.
3252 - tpkg updated with common.sh for common functionality.
3254 7 February 2011: Wouter
3255 - Added regression test for addition of a .net DS to the root, and
3256 cache effects with different TTL for glue and DNSKEY.
3257 - iana portlist updated.
3259 28 January 2011: Wouter
3260 - Fix remove private address does not throw away entire response.
3262 24 January 2011: Wouter
3265 19 January 2011: Wouter
3266 - fix bug#349: no -L/usr for ldns.
3268 18 January 2011: Wouter
3269 - ldns 1.6.8 tarball included.
3272 17 January 2011: Wouter
3273 - add get and set option for harden-below-nxdomain feature.
3274 - iana portlist updated.
3276 14 January 2011: Wouter
3277 - Fix so a changed NS RRset does not get moved name stuck on old
3278 server, for type NS the TTL is not increased.
3280 13 January 2011: Wouter
3281 - Fix prefetch so it does not get stuck on old server for moved names.
3283 12 January 2011: Wouter
3284 - iana portlist updated.
3286 11 January 2011: Wouter
3287 - Fix insecure CNAME sequence marked as secure, reported by Bert
3290 10 January 2011: Wouter
3291 - faster lruhash get_mem routine.
3293 4 January 2011: Wouter
3294 - bug#346: remove ITAR scripts from contrib, the service is discontinued, use the root.
3295 - iana portlist updated.
3297 23 December 2010: Wouter
3298 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
3300 21 December 2010: Wouter
3301 - algorithm compromise protection using the algorithms signalled in
3302 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
3303 and thus, if you have multiple algorithms in your trust-anchor-file
3304 then it will now behave different than before. Also, 5011 rollover
3305 for algorithms needs to be double-signature until the old algorithm
3307 It is not an option, because I see no use to turn the security off.
3308 - iana portlist updated.
3310 17 December 2010: Wouter
3311 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
3312 - fix validation in this case: CNAME to nodata for co-hosted opt-in
3313 NSEC3 insecure delegation, was bogus, fixed to be insecure.
3315 16 December 2010: Wouter
3316 - Fix our 'BDS' license (typo reported by Xavier Belanger).
3318 10 December 2010: Wouter

3330 - iana portlist updated.
3332 18 November 2010: Wouter
3333 - harden-below-nxdomain option, default off (because very old
3334 software may be incompatible). We could enable it by default in
3337 17 November 2010: Wouter
3338 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
3339 - make test output nicer.
3341 15 November 2010: Wouter
3342 - silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
3343 - iana portlist updated.
3344 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
3346 9 November 2010: Wouter
3347 - unbound-anchor compiles with openssl 0.9.7.
3349 8 November 2010: Wouter
3350 - release tag 1.4.7.
3351 - trunk is version 1.4.8.
3352 - Be lenient and accept imgw.pl malformed packet (like BIND).
3354 5 November 2010: Wouter
3355 - do not synthesize a CNAME message from cache for qtype DS.
3357 4 November 2010: Wouter
3358 - Use central entropy to seed threads.
3360 3 November 2010: Wouter
3361 - Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
3363 2 November 2010: Wouter
3367 1 November 2010: Wouter
3368 - GOST code enabled by default (RFC 5933).
3370 27 October 2010: Wouter
3371 - Fix uninit value in dump_infra print.
3372 - Fix validation failure for parent and child on same server with an
3373 insecure childzone and a CNAME from parent to child.
3374 - Configure detects libev-4.00.
3376 26 October 2010: Wouter
3377 - dump_infra and flush_infra commands for unbound-control.
3378 - no timeout backoff if meanwhile a query succeeded.
3379 - Change of timeout code. No more lost and backoff in blockage.
3380 At 12sec timeout (and at least 2x lost before) one probe per IP
3381 is allowed only. At 120sec, the IP is blocked. After 15min, a
3382 120sec entry has a single retry packet.
3384 25 October 2010: Wouter
3385 - Configure errors if ldns is not found.
3387 22 October 2010: Wouter
3388 - Windows 7 fix for the installer.
3390 21 October 2010: Wouter
3391 - Fix bug where fallback_tcp causes wrong roundtrip and edns
3392 observation to be noted in cache. Fix bug where EDNSprobe halted
3393 exponential backoff if EDNS status unknown.
3394 - new unresponsive host method, exponentially increasing block backoff.
3395 - iana portlist updated.
3397 20 October 2010: Wouter
3398 - interface automatic works for some people with ip6 disabled.
3399 Therefore the error check is removed, so they can use the option.
3401 19 October 2010: Wouter
3402 - Fix for request list growth, if a server has long timeout but the
3403 lost counter is low, then its effective rtt is the one without
3404 exponential backoff applied. Because the backoff is not working.
3405 The lost counter can then increase and the server is blacklisted,
3406 or the lost counter does not increase and the server is working
3409 18 October 2010: Wouter
3410 - iana portlist updated.
3412 13 October 2010: Wouter
3413 - Fix TCP so it uses a random outgoing-interface.
3414 - unbound-anchor handles ADDPEND keystate.
3416 11 October 2010: Wouter
3417 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
3418 the zone has a secure delegation hosted on the same server did not
3419 verify as secure (it was insecure by mistake).
3420 - iana portlist updated.
3421 - ldns tarball updated (for reading cachedumps with bad RR data).
3423 1 October 2010: Wouter
3424 - test for unbound-anchor. fix for reading certs.
3425 - Fix alloc_reg_release for longer uptime in out of memory conditions.
3427 28 September 2010: Wouter
3428 - unbound-anchor working, it creates or updates a root.key file.
3429 Use it before you start the validator (e.g. at system boot time).
3431 27 September 2010: Wouter
3432 - iana portlist updated.
3434 24 September 2010: Wouter

3437 23 September 2010: Wouter
3438 - unbound-anchor app, unbound requires libexpat (xml parser library).
3440 22 September 2010: Wouter
3441 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
3442 reverse ipv6 orchid prefix from builtin list.
3443 - iana portlist updated.
3445 17 September 2010: Wouter
3446 - DLV has downgrade protection again, because the RFC says so.
3447 - iana portlist updated.
3449 16 September 2010: Wouter
3450 - Algorithm rollover operational reality intrudes, for trust-anchor,
3451 5011-store, and DLV-anchor if one key matches it's good enough.
3452 - iana portlist updated.
3453 - Fix reported validation error in out of memory condition.
3455 15 September 2010: Wouter
3456 - Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
3458 14 September 2010: Wouter
3459 - increased mesh-max-activation from 1000 to 3000 for crazy domains
3460 like _tcp.slb.com with 262 servers.
3461 - iana portlist updated.
3463 13 September 2010: Wouter
3464 - bug#327: Fix for cannot access stub zones until the root is primed.
3466 9 September 2010: Wouter
3467 - unresponsive servers are not completely blacklisted (because of
3468 firewalls), but also not probed all the time (because of the request
3469 list size it generates). The probe rate is 1%.
3470 - iana portlist updated.
3472 20 August 2010: Wouter
3473 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
3474 iterator get_mem includes priv_get_mem. delegpt nodup removed.
3475 listen_pushback, query_info_allocqname, write_socket, send_packet,
3476 comm_point_set_cb_arg and listen_resume removed.
3478 19 August 2010: Wouter
3479 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
3480 Delegpt structures checked for duplicates always.
3481 No more nameserver lookups generated when depth is full anyway.
3482 - example.conf notes how to do DNSSEC validation and track the root.
3483 - iana portlist updated.
3485 18 August 2010: Wouter
3486 - Fix bug#322: configure does not respect CFLAGS on Solaris.
3487 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
3488 if use sun-cc, but some systems need different flags.
3490 16 August 2010: Wouter
3491 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
3492 changes, uses m4_bpatsubst now.
3493 - make test (or make check) should be more portable and run the unit
3494 test and testbound scripts. (make longtest has special requirements).
3496 13 August 2010: Wouter
3497 - More pleasant remote control command parsing.
3498 - documentation added for return values reported by doxygen 1.7.1.
3499 - iana portlist updated.
3501 9 August 2010: Wouter
3502 - Fix name of rrset printed that failed validation.
3504 5 August 2010: Wouter
3505 - Return NXDOMAIN after chain of CNAMEs ends at name-not-found.
3507 4 August 2010: Wouter
3508 - Fix validation in case a trust anchor enters into a zone with
3509 unsupported algorithms.
3511 3 August 2010: Wouter
3512 - updated ldns tarball with bugfixes.
3513 - release tag 1.4.6.

3523 14 July 2010: Wouter
3524 - Donation text added to README.
3525 - Fix integer underflow in prefetch ttl creation from cache. This
3526 fixes a potential negative prefetch ttl.
3528 12 July 2010: Wouter
3529 - Changed the defaults for num-queries-per-thread/outgoing-range.
3530 For builtin-select: 512/960, for libevent 1024/4096 and for
3531 windows 24/48 (because of win api). This makes the ratio this way
3532 to improve resilience under heavy load. For high performance, use
3533 libevent and possibly higher numbers.
3535 10 July 2010: Wouter
3536 - GOST enabled if SSL is recent and ldns has GOST enabled too.
3537 - ldns tarball updated.
3540 - iana portlist updated.
3541 - Fix validation of qtype DNSKEY when a key-cache entry exists but
3542 no rr-cache entry is used (it expired or prefetch), it then goes
3543 back up to the DS or trust-anchor to validate the DNSKEY.
3546 - Neat function prototypes, unshadowed local declarations.
3549 - failure to chown the pidfile is not fatal any more.
3550 - testbound uses UTC timezone.
3551 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
3552 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
3555 - log if a server is skipped because it is on the donotquery list,
3556 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
3557 - added feature to print configure date, target and options with -h.
3558 - added feature to print event backend system details with -h.
3559 - wdiff is not actually required by make test, updated requirements.
3562 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
3563 must be signed with all algorithms from the DS rrset at the parent.
3564 This is now checked and becomes bogus if not.
3566 28 June 2010: Wouter
3567 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
3568 in overload situations to be about 5 qps for the class of shortly
3570 The capacity of the resolver is then about (numqueriesperthread / 2)
3571 / (average time for such long queries) qps for long queries.
3572 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
3573 qps for short queries, per thread.
3574 - Fix the max number of reply-address count to be applied for duplicate
3575 queries, and not for new query list entries. This raises the memory
3576 usage to a max of (16+1)*numqueriesperthread reply addresses.
3578 25 June 2010: Wouter
3579 - Fix handling of corner case reply from lame server, follows rfc2308.
3580 It could lead to a nodata reply getting into the cache if the search
3581 for a non-lame server turned up other misconfigured servers.
3582 - unbound.h has extern "C" statement for easier include in c++.
3584 23 June 2010: Wouter
3585 - iana portlist updated.
3586 - makedist upgraded cross compile openssl option, like this:
3587 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
3589 22 June 2010: Wouter
3590 - Unbound reports libev or libevent correctly in logs in verbose mode.
3591 - Fix to unload gost dynamic library module for leak testing.
3593 18 June 2010: Wouter
3594 - iana portlist updated.
3596 17 June 2010: Wouter
3597 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
3599 16 June 2010: Wouter
3600 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
3601 assertion was wrong.
3602 - updated ldns tarball.
3604 15 June 2010: Wouter
3605 - tag 1.4.5 created.
3606 - trunk contains 1.4.6 in development.
3607 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
3608 - Fix to use one pointer less for iterator query state store_parent_NS.
3609 - makedist crosscompile to windows uses builtin ldns not host ldns.
3610 - Max referral count from 30 to 130, because 128 one character domains
3612 - added documentation for the histogram printout to syslog.
3614 11 June 2010: Wouter
3615 - When retry to parent the retrycount is not wiped, so failed
3616 nameservers are not tried again.
3617 - iana portlist updated.
3619 10 June 2010: Wouter
3620 - Fix bug where a long loop could be entered, now cycle detection
3621 has a loop-counter and maximum search amount.
3624 - iana portlist updated.
3625 - 1.4.5rc1 tag created.
3628 - ldns tarball updated, 1.6.5.
3629 - review comments, split dependency cycle tracking for parentside
3630 last resort lookups for A and AAAA so there are more lookup options.
3633 - Fix compile warning if compiled without threads.
3634 - updated ldns-tarball with current ldns svn (pre 1.6.5).
3635 - GOST disabled-by-default, the algorithm number is allocated but the
3636 RFC is still has to pass AUTH48 at the IETF.
3639 - Ignore Z flag in incoming messages too.
3640 - Fix storage of negative parent glue if that last resort fails.
3641 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
3642 - new splint flags for newer splint install.
3645 - Fix AD flag handling, it could in some cases mistakenly copy the AD
3646 flag from upstream servers.
3647 - alloc_special_obtain out of memory is not a fatal error any more,
3648 enabling unbound to continue longer in out of memory conditions.
3649 - parentside names are dispreferred but not said to be dnssec-lame.
3650 - parentside check for cached newname glue.
3651 - fix parentside and querytargets modulestate, for dump_requestlist.
3652 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
3653 - fix parentside from cache to be marked dispreferred for bad names.
3656 - iana portlist updated.
3657 - parent-child disagreement approach altered. Older fixes are
3658 removed in place of a more exhaustive search for misconfigured data
3659 available via the parent of a delegation.
3660 This is designed to be throttled by cache entries, with TTL from the
3661 parent if possible. Additionally the loop-counter is used.
3662 It also tests for NS RRset differences between parent and child.
3663 The fetch of misconfigured data should be more reliable and thorough.
3664 It should work reliably even with no or only partial data in cache.
3665 Data received from the child (as always) is deemed more
3666 authoritative than information received from the delegation parent.
3667 The search for misconfigured data is not performed normally.
3670 - Contribution from Migiel de Vos (Surfnet): nagios patch for
3671 unbound-host, in contrib/ (in the source tarball). Makes
3672 unbound-host suitable for monitoring dnssec(-chain) status.
3675 - EDNS timeout code will not fire if EDNS status already known.
3676 - EDNS failure not stored if EDNS status known to work.
3679 - Fix resolution for domains like safesvc.com.cn. If the iterator
3680 can not recurse further and it finds the delegation in a state
3681 where it would otherwise have rejected it outhand if so received
3682 from a cache lookup, then it can try to ask higherup (with loop
3684 - Fix comments in iter_utils:dp_is_useless.
3687 - Fix various compiler warnings from the clang llvm compiler.
3688 - iana portlist updated.
3691 - Fix bug#308: spelling error in variable name in parser and lexer.
3694 - Fix dnssec-missing detection that was turned off by server selection.
3695 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
3696 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
3697 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
3699 29 April 2010: Wouter
3700 - Fix for dnssec lameness detection to use the key cache.
3701 - infra cache entries that are expired are wiped clean. Previously
3702 it was possible to not expire host data (if accessed often).
3704 28 April 2010: Wouter
3705 - ldns tarball updated and GOST support is detected and then enabled.
3706 - iana portlist updated.
3707 - Fix detection of gost support in ldns (reported by Chris Smith).
3709 27 April 2010: Wouter
3710 - unbound-control get_option domain-insecure shows config file items.
3711 - fix retry sequence if prime hints are recursion-lame.
3712 - autotrust anchor file can be initialized with a ZSK key as well.
3713 - harden-referral-path does not result in failures due to max-depth.
3714 You can increase the max-depth by adding numbers (' 0') after the
3715 target-fetch-policy, this increases the depth to which is checked.
3717 26 April 2010: Wouter
3718 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
3719 CPPFLAGS during configure process.
3720 - if libev is installed on the base system (not libevent), detect
3721 it from the event.h header file and link with -lev.
3722 - configlexer.lex gets config.h, and configyyrename.h added by make,
3723 no more double include.
3724 - More strict scrubber (Thanks to George Barwood for the idea):
3725 NS set must be pertinent to the query (qname subdomain nsname).
3726 - Fix bug#307: In 0x20 backoff fix fallback so the number of
3727 outstanding queries does not become -1 and block the request.
3728 Fixed handling of recursion-lame in combination with 0x20 fallback.
3729 Fix so RRsets are compared canonicalized and sorted if the immediate
3730 comparison fails, this makes it work around round-robin sites.
3732 23 April 2010: Wouter
3733 - Squelch log message: sendto failed permission denied for
3734 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
3735 - Fix to fetch data as last resort more tenaciously. When cycle
3736 targets cause the server selection to believe there are more options
3737 when they really are not there, the server selection is reinitiated.
3738 - Fix fetch from blacklisted dnssec lame servers as last resort. The
3739 server's IP address is then given in validator errors as well.
3740 - Fix local-zone type redirect that did not use the query name for
3743 22 April 2010: Wouter
3745 - trunk contains 1.4.5 in development.
3746 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
3747 The validator error message was 'no signatures from ...'.
3749 16 April 2010: Wouter
3750 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
3753 15 April 2010: Wouter
3754 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
3755 example key and signatures for GOST. GOST requires openssl-1.0.0.
3756 GOST is still disabled by default.
3758 9 April 2010: Wouter
3759 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
3760 get into an endless loop, if 0x20 was enabled, and buffers are small
3761 or particular broken packets are received.
3762 - Fix chain of trust with CNAME at an intermediate step, for the DS
3765 8 April 2010: Wouter
3766 - Fix validation of queries with wildcard names (*.example).
3768 6 April 2010: Wouter
3769 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
3770 cache timeout coincided with a server update, the current EDNS
3771 backoff is less sensitive, and does not cache the backoff unless
3772 the backoff actually works and the domain is not expecting DNSSEC.
3773 - GOST support with correct algorithm numbers.
3775 1 April 2010: Wouter
3776 - iana portlist updated.
3778 24 March 2010: Wouter
3779 - unbound control flushed items are not counted when flushed again.
3781 23 March 2010: Wouter
3782 - iana portlist updated.
3784 22 March 2010: Wouter
3785 - unbound-host disables use-syslog from config file so that the
3786 config file for the main server can be used more easily.
3787 - fix bug#301: unbound-checkconf could not parse interface
3788 '0.0.0.0@5353', even though unbound itself worked fine.
3790 19 March 2010: Wouter
3791 - fix fwd_ancil test to pass if the socket options are not supported.
3793 18 March 2010: Wouter
3794 - Fixed random numbers for port, interface and server selection.
3795 Removed very small bias.
3796 - Refer to the listing in unbound-control man page in the extended
3797 statistics entry in the unbound.conf man page.
3799 16 March 2010: Wouter
3800 - Fix interface-automatic for OpenBSD: msg.controllen was too small,
3801 also assertions on ancillary data buffer.
3802 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
3803 - for NSEC3 check if signatures are cached.
3805 15 March 2010: Wouter
3806 - unit test for util/regional.c.
3808 12 March 2010: Wouter
3809 - Reordered configure checks so fork and -lnsl -lsocket checks are
3810 earlier, and thus later checks benefit from and do not hinder them.
3811 - iana portlist updated.
3812 - ldns tarball updated.
3813 - Fix python use when multithreaded.
3814 - Fix solaris python compile.
3815 - Include less in config.h and include per code file for ldns, ssl.
3817 11 March 2010: Wouter
3818 - another memory allocation option: --enable-alloc-nonregional.
3819 exposes the regional allocations to other memory purifiers.
3820 - fix for memory alignment in struct sock_list allocation.
3821 - Fix for MacPorts ldns without ssl default, unbound checks if ldns
3822 has dnssec functionality and uses the builtin if not.
3823 - Fix daemonize on Solaris 10, it did not detach from terminal.
3824 - tag 1.4.3 created.
3825 - trunk is 1.4.4 in development.
3826 - spelling fix in validation error involving cnames.
3828 10 March 2010: Wouter
3829 - --enable-alloc-lite works with test set.
3830 - portability in the testset: printf format conversions, prototypes.
3832 9 March 2010: Wouter
3833 - tag 1.4.2 created.
3834 - trunk is 1.4.3 in development.
3835 - --enable-alloc-lite debug option.
3837 8 March 2010: Wouter
3838 - iana portlist updated.
3840 4 March 2010: Wouter
3841 - Fix crash in control channel code.
3843 3 March 2010: Wouter
3844 - better casts in pipe code, brackets placed wrongly.
3845 - iana portlist updated.
3847 1 March 2010: Wouter
3848 - make install depends on make all.
3849 - Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
3850 - --enable-checking: enables assertions but does not look nonproduction.
3851 - nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
3852 nxdomain and nodata distinguished.
3853 - ldns tarball updated.
3854 - --disable-rpath fixed for libtool not found errors.
3855 - new fedora specfile from Fedora13 in contrib from Paul Wouters.
3857 26 February 2010: Wouter
3858 - Fixup prototype for lexer cleanup in daemon code.
3859 - unbound-control list_stubs, list_forwards, list_local_zones and
3862 24 February 2010: Wouter
3863 - Fix scrubber bug that potentially let NS records through. Reported
3865 - Also delete potential poison references from additional.
3866 - Fix: no classification of a forwarder as lame, throw away instead.
3868 23 February 2010: Wouter
3869 - libunbound ub_ctx_get_option() added.
3870 - unbound-control set_option and get_option commands.
3871 - iana portlist updated.
3873 18 February 2010: Wouter
3874 - A little more strict DS scrubbing.
3875 - No more blacklisting of unresponsive servers, a 2 minute timeout
3877 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.
3878 - pickup ldns compile fix, libdl for libcrypto.
3879 - log 'tcp connect: connection timed out' only in high verbosity.
3880 - unbound-control log_reopen command.
3881 - moved get_option code from unbound-checkconf to util/config_file.c
3883 17 February 2010: Wouter
3884 - Disregard DNSKEY from authority section for chain of trust.
3885 DS records that are irrelevant to a referral scrubbed. Anti-poison.
3886 - iana portlist updated.
3888 16 February 2010: Wouter
3889 - Check for 'no space left on device' (or other errors) when
3890 writing updated autotrust anchors and print errno to log.
3892 15 February 2010: Wouter
3893 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
3894 hardcoded. We made the choice to send out more conservatively,
3895 protecting against an aggregate effect more than protecting a
3896 single user (from their own folly, perhaps in case of misconfig).
3898 12 February 2010: Wouter
3899 - Re-query pattern changed on validation failure. To protect troubled
3900 authority servers, unbound caches a failure for the DNSKEY or DS
3901 records for the entire zone, and only retries that 900 seconds later.
3902 This implies that only a handful of packets are sent extra to the
3903 authority if the zone fails.
3905 11 February 2010: Wouter
3906 - ldns tarball update for long label length syntax error fix.
3907 - iana portlist updated.
3909 9 February 2010: Wouter
3910 - Fixup in compat snprintf routine, %f 1.02 and %g support.
3911 - include math.h for testbound test compile portability.
3913 2 February 2010: Wouter
3914 - Updated url of IANA itar, interim trust anchor repository, in script.
3916 1 February 2010: Wouter
3917 - iana portlist updated.
3918 - configure test for memcmp portability.
3920 27 January 2010: Wouter
3921 - removed warning on format string in validator error log statement.
3922 - iana portlist updated.
3924 22 January 2010: Wouter
3925 - libtool finish the install of unbound python dynamic library.
3927 21 January 2010: Wouter
3928 - acx_nlnetlabs.m4 synchronised with nsd's version.
3930 20 January 2010: Wouter
3931 - Fixup lookup trouble for parent-child domains on the first query.
3933 14 January 2010: Wouter
3934 - Fixup ldns detection to also check for header files.
3936 13 January 2010: Wouter
3937 - prefetch-key option that performs DNSKEY queries earlier in the
3938 validation process, and that could halve the latency on DNSSEC
3939 queries. It takes some extra processing (CPU, a cache is needed).
3941 12 January 2010: Wouter
3942 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
3944 8 January 2010: Wouter
3945 - Fix for parent-child disagreement code which could have trouble
3946 when (a) ipv6 was disabled and (b) the TTL for parent and child
3947 were different. There were two bugs, the parent-side information
3948 is fixed to no longer block lookup of child side information and
3949 the iterator is fixed to no longer attempt to get ipv6 when it is
3950 not enabled and then give up in failure.
3951 - test and fixes to make prefetch actually store the answer in the
3952 cache. Considers some rrsets 'already expired' but does not allow
3953 overwriting of rrsets considered more secure.
3955 7 January 2010: Wouter
3956 - Fixup python documentation (thanks Leo Vandewoestijne).
3957 - Work on cache prefetch feature.
3958 - Stats for prefetch, in log print stats, unbound-control stats
3959 and in unbound_munin plugin.
3961 6 January 2010: Wouter
3962 - iana portlist updated.
3963 - bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.
3964 - verbose output includes parent-side-address notion for lameness.
3965 - documented val-log-level: 2 setting in example.conf and man page.
3966 - change unbound-control-setup from 1024(sha1) to 1536(sha256).
3968 1 January 2010: Wouter
3969 - iana portlist updated.
3971 22 December 2009: Wouter
3972 - configure with newer libtool 2.2.6b.
3974 17 December 2009: Wouter
3977 - trunk to version 1.4.2.
3979 15 December 2009: Wouter
3980 - Answer to qclass=ANY queries, with class IN contents.
3981 Test that validation also works.
3982 - updated ldns snapshot tarball with latest fixes (parsing records).
3984 11 December 2009: Wouter
3985 - on IPv4 UDP turn off DF flag.
3987 10 December 2009: Wouter
3988 - requirements.txt updated with design choice explanations.
3989 - Reading fixes: fix to set unlame when child confirms parent glue,
3990 and fix to avoid duplicate addresses in delegation point.
3991 - verify_rrsig routine checks expiration last.
3993 9 December 2009: Wouter
3994 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
3995 errors generated for domain names like '.example.com'.
3996 - Fix SOA excluded from negative DS responses. Reported by Hauke
3997 Lampe. The negative cache did not include proper SOA records for
3998 negative qtype DS responses which makes BIND barf on it, such
3999 responses are now only used internally.
4000 - Fix negative cache lookup of closestencloser check of DS type bit.
4002 8 December 2009: Wouter
4003 - Fix for lookup of parent-child disagreement domains, where the
4004 parent-side glue works but it does not provide proper NS, A or AAAA
4005 for itself, fixing domains such as motorcaravanners.eu.
4006 - Feature: you can specify a port number in the interface: line, so
4007 you can bind the same interface multiple times at different ports.
4009 7 December 2009: Wouter
4010 - Bug#287: Fix segfault when unbound-control remove nonexistent local
4011 data. Added check to tests.
4013 1 December 2009: Wouter
4014 - Fix crash with module-config "iterator".
4015 - Added unit test that has "iterator" module-config.
4017 30 November 2009: Wouter

4022 - tag for 1.4.0 release.
4023 - 1.4.1 version in trunk.
4024 - Fixup major libtool version to 2 because of why_bogus change.
4025 It was 1:5:0 but should have been 2:0:0.
4027 23 November 2009: Wouter
4028 - Patch from David Hubbard for libunbound manual page.
4029 - Fixup endless spinning in unbound-control stats reported by
4030 Attila Nagy. Probably caused by clock reversal.
4032 20 November 2009: Wouter
4033 - contrib/split-itar.sh contributed by Tom Hendrikx.
4035 19 November 2009: Wouter
4036 - better argument help for unbound-control.

4049 13 November 2009: Wouter
4050 - Fixed validation failure for CNAME to optout NSEC3 nodata answer.
4051 - unbound-host does not fail on type ANY.
4052 - Fixed wireparse failure to put RRSIGs together with data in some
4053 long ANY mix cases, which fixes validation failures.
4055 12 November 2009: Wouter
4056 - iana portlist updated.
4057 - fix manpage errors reported by debian lintian.
4059 - fixup very long vallog2 level error strings.
4061 11 November 2009: Wouter
4062 - ldns tarball updated (to 1.6.2).
4065 10 November 2009: Wouter
4066 - Thanks to Surfnet found bug in new dnssec-retry code that failed
4067 to combine well when combined with DLV and a particular failure.
4068 - Fixed unbound-control -h output about argument optionality.
4071 5 November 2009: Wouter
4072 - lint fixes and portability tests.
4073 - better error text for multiple domain keys in one autotrust file.
4075 2 November 2009: Wouter
4076 - Fix bug where autotrust does not work when started with a DS.
4077 - Updated GOST unit tests for unofficial algorithm number 249
4078 and DNSKEY-format changes in draft version -01.

4087 - iana portlist updated.
4088 - RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
4089 - ldns tarball updated (which also enables rsasha256 support).
4091 27 October 2009: Wouter
4092 - iana portlist updated.
4094 8 October 2009: Wouter
4096 - add val-log-level print to corner case (nameserver.epost.bg).
4097 - more detail to errors from insecure delegation checks.
4098 - Fix double time subtraction in negative cache reported by
4099 Amanda Constant and Hugh Mahon.
4100 - Made new validator error string available from libunbound for
4101 applications. It is in result->why_bogus, a zero-terminated string.
4102 unbound-host prints it by default if a result is bogus.
4103 Also the errinf is public in module_qstate (for other modules).
4105 7 October 2009: Wouter
4106 - retry for validation failure in DS and prime results. Less mem use.
4107 unit test. Provisioning in other tests for requeries.

4113 enabled the substitution of an insecure delegation.
4114 - moved version number to 1.4.0 because of 1.3.4 release with only
4115 the NSEC3 patch from the entry above.
4116 - val-log-level: 2 shows extended error information for validation
4117 failures, but still one (longish) line per failure. For example:
4118 validation failure <example.com. DNSKEY IN>: signature expired from
4119 192.0.2.4 for trust anchor example.com. while building chain of trust
4120 validation failure <www.example.com. A IN>: no signatures from
4121 192.0.2.6 for key example.com. while building chain of trust
4123 6 October 2009: Wouter
4124 - Test set updated to provide additional ns lookup result.
4125 The retry would attempt to fetch the data from other nameservers
4126 for bogus data, and this needed to be provisioned in the tests.

4129 - first validation failure retry code. Retries for data failures.
4132 2 October 2009: Wouter

4141 - review fixes to comments, removed unused code.
4143 25 September 2009: Wouter
4144 - so-rcvbuf: 4m option added. Set this on large busy servers to not
4145 drop the occasional packet in spikes due to full socket buffers.
4146 netstat -su keeps a counter of UDP dropped due to full buffers.
4147 - review of validator/autotrust.c, small fixes and comments.
4149 23 September 2009: Wouter
4150 - 5011 query failed counts verification failures, not lookup failures.
4151 - 5011 probe failure handling fixup.
4152 - test unbound reading of original autotrust data.
4153 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
4154 picked up, otherwise performs initial probe like usual.
4156 22 September 2009: Wouter
4157 - autotrust test with algorithm rollover, new ordering of checks
4158 assists in orderly rollover.
4159 - autotrust test with algorithm rollover to unknown algorithm.
4160 checks if new keys are supported before adding them.
4161 - autotrust test with trust point revocation, becomes unsigned.
4162 - fix DNSSEC-missing-signature detection for minimal responses
4163 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
4165 18 September 2009: Wouter
4166 - autotrust tests, fix trustpoint timer deletion code.
4167 fix count of valid anchors during missing remove.
4168 - autotrust: pick up REVOKE even if not signed with known other keys.

4179 15 September 2009: Wouter
4180 - iana portlist updated.
4182 10 September 2009: Wouter
4183 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
4184 - use linebuffering for log-file: output, this can be significantly
4185 faster than the previous fflush method and enable some class of
4186 resolvers to use high verbosity (for short periods).
4187 Not on windows, because line buffering does not work there.
4189 9 September 2009: Wouter
4190 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
4191 The RRsets would still expire at the normal time, but this would
4192 keep messages bogus in the cache for too long.
4193 - regression test for that bug.
4194 - documented that load_cache is meant for debugging.
4196 8 September 2009: Wouter
4197 - fixup printing errors when load_cache, they were printed to the
4198 SSL connection which broke, now to the log.
4199 - new ldns - with fixed parse of large SOA values.
4201 7 September 2009: Wouter
4202 - autotrust testbound scenarios.
4203 - autotrust fix that failure count is written to file.
4204 - autotrust fix that keys may become valid after add holddown time
4205 alone, before the probe returns.
4207 4 September 2009: Wouter
4208 - Changes to make unbound work with libevent-2.0.3 alpha. (in
4209 configure detection due to new ssl dependency in libevent)
4210 - do not call sphinx for documentation when python is disabled.
4211 - remove EV_PERSIST from libevent timeout code to make the code
4212 compatible with the libevent-2.0. Works with older libevent too.
4213 - fix memory leak in python code.
4215 3 September 2009: Wouter
4216 - Got a patch from Luca Bruno for libunbound support on windows to
4217 pick up the system resolvconf nameservers and hosts there.

4279 - autotrust work, split up DS verification of DNSKEYs.
4281 14 August 2009: Wouter
4282 - unbound-control lookup prints out infra cache information, like RTT.
4283 - Fix bug in DLV lookup reported by Amanda from Secure64.
4284 It could sometimes wrongly classify a domain as unsigned, which
4285 does not give the AD bit on replies.
4287 13 August 2009: Wouter
4288 - autotrust read anchor files. locked trust anchors.
4290 12 August 2009: Wouter

4334 - Fix server selection, so that it waits for open target queries when
4335 faced with lameness.
4337 20 July 2009: Wouter

4384 29 June 2009: Wouter
4385 - ldns trunk r2959 imported as tarball, because of solaris cc compile
4386 support for c99. r2960 for better configure.
4387 - better wrongly_truncated check.
4388 - On Linux, fragment IPv6 datagrams to the IPv6 minimum MTU, to
4389 avoid dropped packets at routers.
4391 26 June 2009: Wouter
4392 - Fix EDNS fallback when EDNS works for short answers but long answers
4395 22 June 2009: Wouter

4405 - harden-referral-path: handle cases where NS is in answer section.
4407 18 June 2009: Wouter
4408 - Fix of message parse bug where (specifically) an NSEC and RRSIG
4409 in the wrong order would be parsed, but put wrongly into internal
4410 structures so that later validation would fail.
4411 - Extreme lenience for wrongly truncated replies where a positive
4412 reply has an NS in the authority but no signatures. They are
4413 turned into minimal responses with only the (secure) answer.
4414 - autoconf 2.63 for configure.
4415 - python warnings suppress. Keep python API away from header files.
4417 17 June 2009: Wouter
4418 - CREDITS entry for cz.nic, sponsoring a 'summer of code' that was

4422 - Fixup opportunistic target query generation to it does not
4423 generate queries that are known to fail.
4424 - Touchup on munin total memory report.
4425 - messages picked out of the cache by the iterator are checked
4426 if their cname chain is still correct and if validation status
4427 has to be reexamined.
4429 15 June 2009: Wouter
4430 - iana portlist updated.
4432 14 June 2009: Wouter
4433 - Fixed bug where cached responses would lose their security
4434 status on second validation, which especially impacted dlv
4435 lookups. Reported by Hauke Lampe.
4437 13 June 2009: Wouter
4438 - bug #254. removed random whitespace from example.conf.
4440 12 June 2009: Wouter
4441 - Fixup potential wrong NSEC picked out of the cache.
4442 - If unfulfilled callbacks are deleted they are called with an error.
4443 - fptr wlist checks for mesh callbacks.
4444 - fwd above stub in configuration works.
4446 11 June 2009: Wouter
4447 - Fix queries for type DS when forward or stub zones are there.
4448 They are performed to higherup domains, and thus treated as if
4449 going to higher zones when looking up the right forward or stub
4450 server. This makes a stub pointing to a local server that has
4451 a local view of example.com signed with the same keys as are
4452 publicly used work. Reported by Johan Ihren.
4453 - Added build-unbound-localzone-from-hosts.pl to contrib, from
4454 Dennis DeDonatis. It converts /etc/hosts into config statements.
4455 - same thing fixed for forward-zone and DS, chain of trust from
4456 public internet into the forward-zone works now. Added unit test.
4459 - openssl key files are opened apache-style, when user is root and
4460 before chrooting. This makes permissions on remote-control key
4461 files easier to set up. Fixes bug #251.
4462 - flush_type and flush_name remove msg cache entries.
4463 - codereview - dp copy bogus setting fix.
4466 - Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
4467 inadvertant behaviour.
4468 - 1.3.0 tarball for release created.
4469 - 1.3.1 development in svn trunk.
4470 - iana portlist updated.
4471 - fix lint from complaining on ldns/sha.h.
4472 - help compiler figure out aliasing in priv_rrset_bad() routine.
4473 - fail to configure with python if swig is not found.
4474 - unbound_munin_ in contrib uses ps to show rss if sbrk does not work.
4477 - fixup bad free() when wrongly encoded DSA signature is seen.
4478 Reported by Paul Wouters.
4479 - review comments from Matthijs.
4482 - --enable-sha2 option. The draft rsasha256 changed its algorithm
4483 numbers too often. Therefore it is more prudent to disable the
4484 RSASHA256 and RSASHA512 support by default.
4485 - ldns trunk included as new tarball.
4486 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.
4489 - fixup doc bug in README reported by Matthew Dempsky.
4492 - update iana port list
4493 - update ldns lib tarball
4496 - detect lack of IPv6 support on XP (with a different error code).
4497 - Fixup a crash-on-exit which was triggered by a very long queue.
4498 Unbound would try to re-use ports that came free, but this is
4499 of course not really possible because everything is deleted.
4500 Most easily triggered on XP (not Vista), maybe because of the
4501 network stack encouraging large messages backlogs.
4502 - change in debug statements.
4503 - Fixed bug that could cause a crash if root prime failed when there
4504 were message backlogs.
4507 - Thanks again to Brett Carr, found an assertion that was not true.
4508 Assertion checked if recursion parent query still existed.
4510 29 April 2009: Wouter
4511 - Thanks to Brett Carr, caught windows resource leak, use
4512 closesocket() and not close() on sockets or else the network stack
4513 starts to leak handles.
4514 - Removed usage of windows Mutex because windows cannot handle enough
4515 mutexes open. Provide own mutex implementation using primitives.
4517 28 April 2009: Wouter
4518 - created svn tag for 1.3.0.
4520 27 April 2009: Wouter

4540 - faster fix for winsock reentrant check.
4541 - fix rsasha512 unit test for new (interim) algorithm number.
4542 - fix test:ldns doesn't like DOS line endings in keyfiles on unix.
4543 - fix compile warning on ubuntu (configlexer fwrite return value).
4544 - move python include directives into CPPFLAGS instead of CFLAGS.
4546 16 April 2009: Wouter
4547 - winsock event handler exit very quickly on signal, even if
4549 - iana portlist updated.
4550 - fixup windows winsock handler reentrant problem.
4552 14 April 2009: Wouter

4554 - makedist.sh; better help text.
4555 - cache-min-ttl option and tests.
4556 - mingw detect error condition on TCP sockets (NOTCONN).
4558 9 April 2009: Wouter
4559 - Fix for removal of RSASHA256_NSEC3 protonumber from ldns.
4560 - ldns tarball updated.
4561 - iana portlist update.
4562 - detect GOST support in openssl-1.0.0-beta1, and fix compile problem
4563 because that openssl defines the name STRING for itself.
4565 6 April 2009: Wouter
4566 - windows compile fix.
4567 - Detect FreeBSD jail without ipv6 addresses assigned.
4568 - python libunbound wrapper unit test.
4569 - installs the following files. Default is to not build them.
4570 from configure --with-pythonmodule:
4571 /usr/lib/python2.x/site-packages/unboundmodule.py
4572 from configure --with-pyunbound:
4573 /usr/lib/python2.x/site-packages/unbound.py
4574 /usr/lib/python2.x/site-packages/_unbound.so*
4575 The example python scripts (pythonmod/examples and
4576 libunbound/python/examples) are not installed.
4577 - python invalidate routine respects packed rrset ids and locks.
4578 - clock skew checks in unbound, config statements.
4579 - nxdomain ttl considerations in requirements.txt
4581 3 April 2009: Wouter
4582 - Fixed a bug that caused messages to be stored in the cache too
4583 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
4584 targets have been more vulnerable to the TTL miscalculation bug.
4585 - documentation test fixed for python addition.
4587 2 April 2009: Wouter
4588 - pyunbound (libunbound python plugin) compiles using libtool.
4589 - documentation for pythonmod and pyunbound is generated in doc/html.
4590 - iana portlist updated.
4591 - fixed bug in unbound-control flush_zone where it would not flush
4592 every message in the target domain. This especially impacted
4593 NXDOMAIN messages which could remain in the cache regardless.
4594 - python module test package.
4596 1 April 2009: Wouter
4597 - suppress errors when trying to contact authority servers that gave
4598 ipv6 AAAA records for their nameservers with ipv4 mapped contents.
4599 Still tries to do so, could work when deployed in intranet.
4600 Higher verbosity shows the error.
4601 - new libunbound calls documented.
4602 - pyunbound in libunbound/python. Removed compile warnings.

4656 - Fix for and test for unknown algorithms in a trust anchor
4657 definition. Trust anchors with no supported algos are ignored.
4658 This means a (higher)DS or DLV entry for them could succeed, and
4659 otherwise they are treated as insecure.
4660 - domain-insecure: "example.com" statement added. Sets domain
4661 insecure regardless of chain of trust DSs or DLVs. The inverse

4747 You can provide your own PGP key and trust repo, or can use the
4748 builtin. The program uses wget and gpg to work.
4749 - iana portlist updated.
4750 - update-itar.sh: using ftp:// urls because https godaddy certificate
4751 is not available everywhere and then gives fatal errors. The
4752 security is provided by pgp signature.
4754 18 February 2009: Wouter
4755 - more cycle detection. Also for target queries.
4756 - fixup bug where during deletion of the mesh queries the callbacks

4794 - verbosity level 5 logs customer IP for new requestlist entries.
4795 - test fix, lexer and cancel test.

4797 in the log file as Feb 06 13:45:26 (like syslog does).
4798 - detect event_base_new in libevent-1.4.1 and later and use it.
4799 - #231 unbound-checkconf -o option prints that value from config file.
4800 Useful for scripting in management scripts and the like.
4802 5 February 2009: Wouter
4803 - ldns 1.5.0 rc as tarball included.
4804 - 1.3.0 development continues:
4805 change in libunbound API: ub_cancel can return an error, that
4806 the async_id did not exist, or that it was already delivered.
4807 The result could have been delivered just before the cancel
4808 routine managed to acquire the lock, so a caller may get the
4809 result at the same time they call cancel. For this case,
4810 ub_cancel tries to return an error code.
4811 Fixes race condition in ub_cancel() libunbound function.
4812 - MacOSX Leopard cleaner text output from configure.
4813 - initgroups(3) is called to drop secondary group permissions, if
4815 - configure option --with-ldns-builtin forces the use of the
4816 inluded ldns package with the unbound source. The -I include
4817 is put before the others, so it avoids bad include files from
4818 an older ldns install.
4819 - daemon(3) posix call is used when available.
4820 - testbound test for older fix added.
4822 4 February 2009: Wouter

4831 16 January 2009: Wouter
4832 - more quiet about ipv6 network failures, i.e. when ipv6 is not
4833 available (network unreachable). Debug still printed on high
4835 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
4836 debugging with unbound-host -4 -d ...
4837 - more cycle detection for NS-check, addr-check, root-prime and
4838 stub-prime queries in the iterator. Avoids possible deadlock
4841 15 January 2009: Wouter
4842 - bug #229: fixup configure checks for compilation with Solaris
4843 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc

4845 - fix bug where unbound could crash using libevent 1.3 and older.
4846 - update testset for recent retry change.
4848 14 January 2009: Wouter
4849 - 1.2.1 feature: negative caching for failed queries.
4850 Queries that failed are cached for 5 seconds (NORR_TTL).
4851 If the failure is local, like out of memory, it is not cached.
4852 - the TTL comparison for the cache used different comparisons,
4853 causing many cache responses that used the iterator and validator
4854 state machines unnecessarily.
4855 - retry from 4 to 5 so that EDNS drop retry is part of the first
4856 query resolve attempt, and cached error does not stop EDNS fallback.
4857 - remove debug prints that protect against bad referrals.
4858 - honor QUIET=no on make commandline (or QUIET=yes ).

4887 statements. (Adapted from patch by Paul Wouters).
4888 - typo fix and iana portlist updated.
4889 - porting testsuite; unused var warning, and type fixup.
4891 6 January 2009: Wouter
4892 - fixup packet-of-death when compiled with --enable-debug.
4893 A malformed packet could cause an internal assertion failure.
4894 - added test for HINFO canonicalisation behaviour.
4895 - fixup reported problem with transparent local-zone data where
4896 queries with different type could get nxdomain. Now queries
4897 with a different name get resolved normally, with different type
4898 get a correct NOERROR/NODATA answer.
4899 - HINFO no longer downcased for validation, making unbound compatible
4901 - fix reading included config files when chrooted.
4902 Give full path names for include files.
4903 Relative path names work if the start dir equals the working dir.
4904 - fix libunbound message transport when no packet buffer is available.
4906 5 January 2009: Wouter
4907 - fixup getaddrinfo failure handling for remote control port.

4909 - fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
4910 - comm_timer_set performs base_set operation after event_add.
4912 18 December 2008: Wouter

4914 some zones that had correct DLV keys as insecure.
4915 - follows -rc makedist from ldns changes (no _rc).
4916 - ldns tarball updated with 1.4.1rc for DLV unit test.

4929 - follow makedist improvements from ldns, for maintainers prereleases.
4930 - snapshot version uses _ not - to help rpm distinguish the
4933 11 December 2008: Wouter
4934 - better fix for bug #219: use LOG_NDELAY with openlog() call.
4935 Thanks to Tamas Tevesz.
4937 9 December 2008: Wouter
4938 - bug #221 fixed: unbound checkconf checks if key files exist if
4939 remote control is enabled. Also fixed NULL printf when not chrooted.
4940 - iana portlist updated.
4942 3 December 2008: Wouter
4943 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
4944 freezes up unbound if this was compiled without threading, and
4945 was using multiple processes.
4946 - iana portlist updated.
4947 - test for remote control with interprocess communication.
4948 - created command distribution mechanism so that remote control
4949 commands other than 'stats' work on all processes in a nonthreaded
4950 compiled version. dump/load cache work, on the first process.
4951 - fixup remote control local_data addition memory corruption bug.
4953 1 December 2008: Wouter

4960 - fixup testcode/streamtcp to work on vista/mingw.
4961 - root-hints test checks version of dig required.
4962 - blacklisted servers are polled at a low rate (1%) to see if they
4963 come back up. But not if there is some other working server.
4965 24 November 2008: Wouter
4966 - document that the user of the server daemon needs read privileges
4967 on the keys and certificates generated by unbound-control-setup.
4968 This is different per system or distribution, usually, running the
4969 script under the same username as the server uses suffices.
4970 i.e. sudo -u unbound unbound-control-setup
4971 - testset port to vista/mingw.
4972 - tcp_sigpipe to freebsd port.
4974 21 November 2008: Wouter
4975 - fixed tcp accept, errors were printed when they should not.
4976 - unbound-control-setup.sh removes read/write permissions other
4977 from the keys it creates (as suggested by Dmitriy Demidov).

4998 17 November 2008: Wouter
4999 - theoretical fix for problems reported on mailing list.
5000 If a delegation point has no A but only AAAA and do-ip6 is no,
5001 resolution would fail. Fixed to ask for the A and AAAA records.
5002 It has to ask for both always, so that it can fail quietly, from
5003 TLD perspective, when a zone is only reachable on one transport.
5004 - test for above, only AAAA and doip6 is no. Fix causes A record
5005 for nameserver to be fetched.
5006 - fixup address duplication on cache fillup for delegation points.
5007 - testset updated for new query answer requirements.

5022 12 November 2008: Wouter
5023 - add unbound-control manpage to makedist replace list.
5025 11 November 2008: Wouter
5026 - unit test for negative cache, stress tests the refcounting.
5027 - fix for refcounting error that could cause fptr_wlist fatal exit
5028 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
5029 Attila Nagy for testing).
5030 - nicer comments in cachedump about failed RR to string conversion.

5053 had outstanding (TCP) replies.
5054 - DNAMEs used from cache have their synthesized CNAMEs initialized

5057 - fixed memleak at exit for nsec3 negative cached zones.
5058 - fixed memleak for the keyword 'nodefault' when reading config.

5081 - CFLAGS are picked up by configure from the environment.
5082 - iana portlist updated.
5083 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
5084 - new stub-prime: yesno option. Default is off, so it does not prime.
5085 can be turned on to get same behaviour as previous unbound release.
5086 - made automated test that checks if builtin root hints are uptodate.
5087 - finished draft-wijngaards-dnsext-resolver-side-mitigation

5101 - do not query bogus nameservers. It is like nameservers that have
5102 the NS or A or AAAA record bogus are listed as donotquery.
5103 - if server selection is faced with only bad choices, it will
5104 attempt to get more options to be fetched.
5105 - changed bogus-ttl default value from 900 to 60 seconds.
5106 In anticipation that operator caused failures are more likely than
5107 actual attacks at this time. And thus repeated validation helps
5108 the operators get the problem fixed sooner. It makes validation
5109 failures go away sooner (60 seconds after the zone is fixed).
5110 Also it is likely to try different nameserver targets every minute,
5111 so that if a zone is bad on one server but not another, it is
5112 likely to pick up the 'correct' one after a couple minutes,
5113 and if the TTL is big enough that solves validation for the zone.
5114 - fixup unbound-control compilation on windows.
5116 17 October 2008: Wouter
5117 - port Leopard/G5: fixup type conversion size_t/uint32.

5121 and attemps to validate the entries.
5123 16 October 2008: Wouter
5124 - Fixup negative TTL values appearing (reported by Attila Nagy).
5126 15 October 2008: Wouter

5129 as well as very careful NS caching (only when doing NS query).
5130 A, AAAA use the delegation from the NS-query.
5132 14 October 2008: Wouter
5133 - fwd_three.tpkg test was flaky. If the three requests hit the
5134 wrong threads by chance (or bad OS) then the test would fail.
5135 Made less flaky by increasing number of retries.
5136 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.

5138 Which includes the ldns_dname_absolute fix.
5139 - fwd_three test remains flaky now that unbound does not stop
5140 listening when full. Thus, removed timeout problem.
5141 It may be serviced by three threads, or maybe by one.
5142 Mostly only useful for lock-check testing now.
5144 13 October 2008: Wouter
5145 - fixed recursion servers deployed as authoritative detection, so
5146 that as a last resort, a +RD query is sent there to get the
5148 - iana port list update.

5174 can restart unbound exactly when needed.
5176 30 September 2008: Wouter
5177 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
5178 - tests for sha256 support and downgrade resistance.

5182 Like when running NSD to host a local zone, on the same machine.
5183 The noprime feature. manpages more explanation. Added a test for it.
5184 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"

5637 - removed base_port.
5638 - created 256-port ephemeral space for the OS, 59802 available.
5639 - fixup consistency of port_if out array during heavy use.
5641 10 April 2008: Wouter
5642 - --with-libevent works with latest libevent 1.4.99-trunk.
5643 - added log file statistics perl script to contrib.
5644 - automatic iana ports update from makefile. 60058 available.
5646 9 April 2008: Wouter
5647 - configure can detect libev(from its build directory) when passed
5648 --with-libevent=/home/wouter/libev-3.2
5649 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
5650 - unused commpoints not listed in epoll list.
5651 - statistics-cumulative option so that the values are not reset.
5652 - config creates array of available ports, 61841 available,
5653 it excludes <1024 and iana assigned numbers.
5654 config statements to modify the available port numbers.
5656 8 April 2008: Wouter
5657 - unbound tries to set the ulimit fds when started as server.
5658 if that does not work, it will scale back its requirements.
5660 27 March 2008: Wouter
5661 - documented /dev/random symlink from chrootdir as FAQ entry.
5663 26 March 2008: Wouter
5664 - implemented AD bit signaling. If a query sets AD bit (but not DO)
5665 then the AD bit is set in the reply if the answer validated.
5666 Without including DNSSEC signatures. Useful if you have a trusted
5667 path from the client to the resolver. Follows dnssec-updates draft.
5669 25 March 2008: Wouter
5670 - implemented check that for NXDOMAIN and NOERROR answers a query
5671 section must be present in the reply (by the scrubber). And it must
5672 be equal to the question sent, at least lowercase folded.
5673 Previously this feature happened because the cache code refused
5674 to store such messages. However blocking by the scrubber makes
5675 sure nothing gets into the RRset cache. Also, this looks like a
5676 timeout (instead of an allocation failure) and this retries are
5677 done (which is useful in a spoofing situation).
5678 - RTT banding. Band size 400 msec, this makes band around zero (fast)
5679 include unknown servers. This makes unbound explore unknown servers.
5681 7 March 2008: Wouter
5682 - -C config feature for harvest program.
5683 - harvest handles CNAMEs too.
5685 5 March 2008: Wouter
5686 - patch from Hugo Koji Kobayashi for iterator logs spelling.
5688 4 March 2008: Wouter
5689 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
5690 of a cname trust chain is lower; not full answer_AA.
5691 - test for this fix.
5692 - default config file location is /usr/local/etc/unbound.
5693 Thus prefix is used to determine the location. This is also the
5694 chroot and pidfile default location.
5696 3 March 2008: Wouter
5697 - Create 0.10 svn tag.
5698 - 0.11 version in trunk.
5699 - indentation nicer.
5701 29 February 2008: Wouter
5702 - documentation update.
5703 - fixup port to Solaris of perf test tool.
5704 - updated ldns-tarball with decl-after-statement fixes.
5706 28 February 2008: Wouter
5707 - fixed memory leaks in libunbound (during cancellation and wait).
5708 - libunbound returns the answer packet in full.
5709 - snprintf compat update.
5710 - harvest performs lookup.
5711 - ldns-tarball update with fix for ldns_dname_label.
5712 - installs to sbin by default.
5713 - install all manual pages (unbound-host and libunbound too).
5715 27 February 2008: Wouter
5716 - option to use caps for id randomness.
5717 - config file option use-caps-for-id: yes
5718 - harvest debug tool
5720 26 February 2008: Wouter
5721 - delay utility delays TCP as well. If the server that is forwarded
5722 to has a TCP error, the delay utility closes the connection.
5723 - delay does REUSE_ADDR, and can handle a server that closes its end.
5724 - answers use casing from query.
5726 25 February 2008: Wouter
5727 - delay utility works. Gets decent thoughput too (>20000).
5729 22 February 2008: Wouter
5730 - +2% for recursions, if identical queries (except for destination
5731 and query ID) in the reply list, avoid re-encoding the answer.
5732 - removed TODO items for optimizations that do not show up in
5734 - default is now minievent - not libevent. As its faster and
5735 not needed for regular installs, only for very large port ranges.
5736 - loop check different speedup pkt-dname-reading, 1% faster for
5737 nocache-recursion check.
5738 - less hashing during msg parse, 4% for recursion.
5739 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
5740 - some speed results noted:
5741 optimization resulted in +40% for recursion (cache miss) and
5742 +70 to +80 for cache hits, and +96% for version.bind.
5743 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
5744 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
5745 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
5746 So, unbound can be about equal qps to NSD in cache hits.
5747 And about 3.4x faster than BIND in cache performance.
5748 - delay utility for testing.
5750 21 February 2008: Wouter
5751 - speedup of root-delegation message encoding by 15%.
5752 - minor speedup of compress tree_lookup, maybe 1%.
5753 - speedup of dname_lab_cmp and memlowercmp - the top functions in
5754 profiler output, maybe a couple percent when it matters.
5756 20 February 2008: Wouter
5757 - setup speec_cache for need-ldns-testns in dotests.
5758 - check number of queued replies on incoming queries to avoid overload
5760 - fptr whitelist checks are not disabled in optimize mode.
5761 - do-daemonize config file option.
5762 - minievent time share initializes time at start.
5763 - updated testdata for nsec3 new algorithm numbers (6, 7).
5764 - small performance test of packet encoding (root delegation).
5766 19 February 2008: Wouter
5767 - applied patch to unbound-host man page from Jan-Piet Mens.
5768 - fix donotquery-localhost: yes default (it erroneously was switched
5770 - time is only gotten once and the value is shared across unbound.
5771 - unittest cleans up crypto, so that it has no memory leaks.
5772 - mini_event shares the time value with unbound this results in
5773 +3% speed for cache responses and +9% for recursions.
5774 - ldns tarball update with new NSEC3 sign code numbers.
5775 - perform several reads per UDP operation. This improves performance
5776 in DoS conditions, and costs very little in normal conditions.
5777 improves cache response +50%, and recursions +10%.
5778 - modified asynclook test. because the callback from async is not
5779 in any sort of lock (and thus can use all library functions freely),
5780 this causes a tiny race condition window when the last lock is
5781 released for a callback and a new cancel() for that callback.
5782 The only way to remove this is by putting callbacks into some
5783 lock window. I'd rather have the small possibility of a callback
5784 for a cancelled function then no use of library functions in
5785 callbacks. Could be possible to only outlaw process(), wait(),
5786 cancel() from callbacks, by adding another lock, but I'd rather not.
5788 18 February 2008: Wouter
5789 - patch to unbound-host from Jan-Piet Mens.
5790 - unbound host prints errors if fails to configure context.
5791 - fixup perf to resend faster, so that long waiting requests do
5792 not hold up the queue, they become lost packets or SERVFAILs,
5793 or can be sent a little while later (i.e. processing time may
5794 take long, but throughput has to be high).
5795 - fixup iterator operating in no cache conditions (RD flag unset
5797 - streamlined code for RD flag setting.
5798 - profiled code and changed dname compares to be faster.
5799 The speedup is about +3% to +8% (depending on the test).
5800 - minievent tests for eintr and eagain.
5802 15 February 2008: Wouter
5803 - added FreeBSD rc.d script to contrib.
5804 - --prefix option for configure also changes directory: pidfile:
5805 and chroot: defaults in config file.
5806 - added cache speed test, for cache size OK and cache too small.
5808 14 February 2008: Wouter
5809 - start without a config file (will complain, but start with
5811 - perf test program works.
5813 13 February 2008: Wouter
5815 - 1.0 development. Printout ldns version on unbound -h.
5816 - start of perf tool.
5817 - bugfix to read empty lines from /etc/hosts.

5824 - changed library to use ub_ instead of ub_val_ as prefix.
5825 - statistics output text nice.
5826 - etc/hosts handling.
5827 - library function to put logging to a stream.
5828 - set any option interface.

5831 - test program for multiple queries over a TCP channel.
5832 - tpkg test for stream tcp queries.
5833 - unbound replies to multiple TCP queries on a TCP channel.
5834 - fixup misclassification of root referral with NS in answer
5835 when validating a nonrec query.
5837 - layout of manpages, spelling fix in header, manpages process by
5838 makedist, list asynclook and tcpstream tests as ldns-testns
5841 7 February 2008: Wouter
5842 - moved up all current level 2 to be level 3. And 3 to 4.
5843 to make room for new debug level 2 for detailed information
5845 - verbosity level 2. Describes recursion and validation.
5846 - cleaner configure script and fixes for libevent solaris.
5847 - signedness for log output memory sizes in high verbosity.
5849 6 February 2008: Wouter
5850 - clearer explanation of threading configure options.
5851 - fixup asynclook test for nothreading (it creates only one process
5852 to do the extended test).
5853 - changed name of ub_val_result_free to ub_val_resolve_free.
5854 - removes warning message during library linking, renamed
5855 libunbound/unbound.c -> libunbound.c and worker to libworker.
5856 - fallback without EDNS if result is NOTIMPL as well as on FORMERR.
5858 5 February 2008: Wouter
5859 - statistics-interval: seconds option added.
5860 - test for statistics option
5861 - ignore errors making directories, these can occur in parallel builds
5862 - fixup Makefile strip command and libunbound docs typo.
5864 31 January 2008: Wouter
5865 - bg thread/process reads and writes the pipe nonblocking all the time
5866 so that even if the pipe is buffered or so, the bg thread does not
5867 block, and services both pipes and queries.
5869 30 January 2008: Wouter
5870 - check trailing / on chrootdir in checkconf.
5871 - check if root hints and anchor files are in chrootdir.
5872 - no route to host tcp error is verbosity level 2.
5873 - removed unused send_reply_iov. and its configure check.
5874 - added prints of 'remote address is 1.2.3.4 port 53' to errors
5875 from netevent; the basic socket errors.
5877 28 January 2008: Wouter
5878 - fixup uninit use of buffer by libunbound (query id, flags) for
5880 - fixup uninit warning from random.c; also seems to fix sporadic
5881 sigFPE coming out of openssl.
5882 - made openssl entropy warning more silent for library use. Needs
5884 - fixup forgotten locks for rbtree_searches on ctx->query tree.
5885 - random generator cleanup - RND_STATE_SIZE removed, and instead
5886 a super-rnd can be passed at init to chain init random states.
5887 - test also does lock checks if available.
5888 - protect config access in libworker_setup().
5889 - libevent doesn't like comm_base_exit outside of runloop.
5890 - close fds after removing commpoints only (for epoll, kqueue).
5892 25 January 2008: Wouter
5893 - added tpkg for asynclook and library use.
5894 - allows localhost to be queried when as a library.
5895 - fixup race condition between cancel and answer (in case of
5896 really fast answers that beat the cancel).
5897 - please doxygen, put doxygen comment in one place.
5898 - asynclook -b blocking mode and test.
5899 - refactor asynclook, nicer code.
5900 - fixup race problems from opensll in rand init from library, with
5901 a mutex around the rand init.
5902 - fix pass async_id=NULL to _async resolve().
5903 - rewrote _wait() routine, so that it is threadsafe.
5904 - cancelation is threadsafe.
5905 - asynclook extended test in tpkg.
5906 - fixed two races where forked bg process waits for (somehow shared?)
5907 locks, so does not service the query pipe on the bg side.
5908 Now those locks are only held for fg_threads and for bg_as_a_thread.
5910 24 January 2008: Wouter
5911 - tested the cancel() function.
5912 - asynclook -c (cancel) feature.

5920 23 January 2008: Wouter
5921 - removed debug prints from if-auto, verb-algo enables some.
5922 - libunbound QUIT setup, remove memory leaks, when using threads
5923 will share memory for passing results instead of writing it over
5924 the pipe, only writes ID number over the pipe (towards the handler
5925 thread that does process() ).
5927 22 January 2008: Wouter
5928 - library code for async in libunbound/unbound.c.
5929 - fix link testbound.
5930 - fixup exit bug in mini_event.
5931 - background worker query enter and result functions.
5932 - bg query test application asynclook, it looks up multiple
5933 hostaddresses (A records) at the same time.
5935 21 January 2008: Wouter
5936 - libworker work, netevent raw commpoints, write_msg, serialize.
5938 18 January 2008: Wouter
5939 - touch up of manpage for libunbound.
5940 - support for IP_RECVDSTADDR (for *BSD ip4).
5941 - fix for BSD, do not use ip4to6 mapping, make two sockets, once
5942 ip6 and once ip4, uses socket options.
5943 - goodbye ip4to6 mapping.
5944 - update ldns-testpkts with latest version from ldns-trunk.
5945 - updated makedist for relative ldns pathnames.
5946 - library API with more information inside the result structure.

5950 - fixup configure in case -lldns is installed.
5951 - fixup a couple of doxygen warnings, about enum variables.
5952 - interface-automatic now copies the interface address from the
5953 PKT_INFO structure as well.
5954 - manual page with library API, all on one page 'man libunbound'.
5955 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
5957 16 January 2008: Wouter
5958 - incoming queries to the server with TC bit on are replied FORMERR.
5959 - interface-automatic replied the wrong source address on localhost
5960 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
5961 to use ifnum=-1 to mean 'no interface, use kernel route'.
5963 15 January 2008: Wouter
5964 - interface-automatic feature. experimental. Nice for anycast.
5965 - tpkg test for ip6 ancillary data.
5966 - removed debug prints.
5967 - porting experience, define for Solaris, test refined for BSD
5968 compatibility. The feature probably will not work on OpenBSD.
5969 - makedist fixup for ldns-src in build-dir.
5971 14 January 2008: Wouter
5972 - in no debug sets NDEBUG to remove asserts.
5973 - configure --enable-debug is needed for dependency generation
5974 for assertions and for compiler warnings.
5975 - ldns.tgz updated with ldns-trunk (where buffer.h is updated).
5976 - fix lint, unit test in optimize mode.
5977 - default access control allows ::ffff:127.0.0.1 v6mapped localhost.
5979 11 January 2008: Wouter
5980 - man page, warning removed.
5981 - added text describing the use of stub zones for private zones.
5982 - checkconf tests for bad hostnames (IP address), and for doubled
5984 - memory sizes can be given with 'k', 'Kb', or M or G appended.
5986 10 January 2008: Wouter
5987 - typo in example.conf.
5988 - made using ldns-src that is included the package more portable
5989 by linking with .lo instead of .o files in the ldns package.
5990 - nicer do-ip6: yes/no documentation.
5991 - nicer linking of libevent .o files.
5992 - man pages render correctly on solaris.
5994 9 January 2008: Wouter
5995 - fixup openssl RAND problem, when the system is not configured to
5996 give entropy, and the rng needs to be seeded.
5998 8 January 2008: Wouter
5999 - print median and quartiles with extensive logging.
6001 4 January 2008: Wouter
6002 - document misconfiguration in private network.
6004 2 January 2008: Wouter
6005 - fixup typo in requirements.
6006 - document that 'refused' is a better choice than 'drop' for
6007 the access control list, as refused will stop retries.
6009 7 December 2007: Wouter
6010 - unbound-host has a -d option to show what happens. This can help
6011 with debugging (why do I get this answer).
6012 - fixup CNAME handling, on nodata, sets and display canonname.
6013 - dot removed from CNAME display.
6014 - respect -v for NXDOMAINs.
6015 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
6016 - size_t to int for portability of the header file.
6017 - fixup bogus handling.
6018 - dependencies and lint for unbound-host.
6020 6 December 2007: Wouter
6021 - library resolution works in foreground mode, unbound-host app
6023 - unbound-host prints rdata using ldns.
6024 - unbound-host accepts trust anchors, and prints validation
6025 information when you give -v.
6027 5 December 2007: Wouter
6028 - locking in context_new() inside the function.
6029 - setup of libworker.
6031 4 December 2007: Wouter
6032 - minor Makefile fixup.
6033 - moved module-stack code out of daemon/daemon into services/modstack,
6034 preparing for code-reuse.
6035 - move context into own header file.
6036 - context query structure.
6037 - removed unused variable pwd from checkconf.
6038 - removed unused assignment from outside netw.
6039 - check timeval length of string.
6040 - fixup error in val_utils getsigner.
6041 - fixup same (*var) error in netblocktostr.
6042 - fixup memleak on parse error in localzone.
6043 - fixup memleak on packet parse error.
6044 - put ; after union in parser.y.
6045 - small hardening in iter_operate against iq==NULL.
6046 - hardening, if error reply with rcode=0 (noerror) send servfail.
6047 - fixup same (*var) error in find_rrset in msgparse, was harmless.
6048 - check return value of evtimer_add().
6049 - fixup lockorder in lruhash_reclaim(), building up a list of locked
6050 entries one at a time. Instead they are removed and unlocked.
6051 - fptr_wlist for markdelfunc.
6052 - removed is_locked param from lruhash delkeyfunc.
6053 - moved bin_unlock during bin_split purely to please.
6055 3 December 2007: Wouter
6056 - changed checkconf/ to smallapp/ to make room for more support tools.
6057 (such as unbound-host).
6058 - install dirs created with -m 755 because they need to be accessible.
6059 - library extensive featurelist added to TODO.
6060 - please doxygen, lint.
6061 - library test application, with basic functionality.
6062 - fix for building in a subdirectory.
6063 - link lib fix for Leopard.
6065 30 November 2007: Wouter
6066 - makefile that creates libunbound.la, basic file or libunbound.a
6067 when creating static executables (no libtool).
6070 29 November 2007: Wouter
6071 - 0.9 public API start.
6073 28 November 2007: Wouter
6074 - Changeup plan for 0.8 - no complication needed, a simple solution
6075 has been chosen for authoritative features.
6076 - you can use single quotes in the config file, so it is possible
6077 to specify TXT records in local data.
6078 - fixup small memory problem in implicit transparent zone creation.
6079 - test for implicit zone creation and multiple RR RRsets local data.
6080 - local-zone nodefault test.
6081 - show testbound testlist on commit.
6082 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
6083 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
6085 - nicer verbosity: 0 and 1 levels.
6086 - lower nonRDquery chance of eliciting wrongly typed validation
6087 requiring message from the cache.
6088 - fix for nonRDquery validation typing; nodata is detected when
6089 SOA record in auth section (all validation-requiring nodata messages
6090 have a SOA record in authority, so this is OK for the validator),
6091 and NS record is needed to be a referral.
6092 - duplicate checking when adding NSECs for a CNAME, and test.
6093 - created svn tag 0.8, after completing testbed tests.
6095 27 November 2007: Wouter
6096 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
6097 - set size of msgparse lookup table to 32, from 1024, so that its size
6098 is below the 2048 regional large size threshold, and does not cause
6099 a call to malloc when a message is parsed.
6100 - update of memstats tool to print number of allocation calls.
6101 This is what is taking time (not space) and indicates the avg size
6102 of the allocations as well. region_alloc stat is removed.
6104 22 November 2007: Wouter
6105 - noted EDNS in-the-middle dropping trouble as a TODO.
6106 At this point theoretical, no user trouble has been reported.
6107 - added all default AS112 zones.
6108 - answers from local zone content.
6109 * positive answer, the rrset in question
6110 * nodata answer (exist, but not that type).
6111 * nxdomain answer (domain does not exist).
6112 * empty-nonterminal answer.
6113 * But not: wildcard, nsec, referral, rrsig, cname/dname,
6114 or additional section processing, NS put in auth.
6115 - test for correct working of static and transparent and couple
6116 of important defaults (localhost, as112, reverses).
6117 Also checks deny and refuse settings.
6118 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
6120 21 November 2007: Wouter
6121 - local zone internal data setup.
6123 20 November 2007: Wouter
6124 - 0.8 - str2list config support for double string config options.
6125 - local-zone and local-data options, config storage and documentation.
6127 19 November 2007: Wouter
6128 - do not downcase NSEC and RRSIG for verification. Follows
6129 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
6130 - fixup leaking unbound daemons at end of tests.
6131 - README file updated.
6132 - nice libevent not found error.
6133 - README talks about gnu make.
6134 - 0.8: unit test for addr_mask and fixups for it.
6135 and unit test for addr_in_common().
6136 - 0.8: access-control config file element.
6137 and unit test rpl replay file.
6138 - 0.8: fixup address reporting from netevent.
6140 16 November 2007: Wouter
6141 - privilege separation is not needed in unbound at this time.
6142 TODO item marked as such.
6143 - created beta-0.7 branch for support.
6144 - tagged 0.7 for beta release.
6145 - moved trunk to 0.8 for 0.8(auth features) development.
6146 - 0.8: access control list setup.
6148 15 November 2007: Wouter
6149 - review fixups from Jelte.
6151 14 November 2007: Wouter
6152 - testbed script does not recreate configure, since its in svn now.
6153 - fixup checkconf test so that it does not test
6154 /etc/unbound/unbound.conf.
6157 13 November 2007: Wouter
6158 - remove debug print.
6159 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
6161 12 November 2007: Wouter
6162 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
6164 - bugreports to unbound-bugs@nlnetlabs.nl
6165 - fixup testbound so it exits cleanly.
6166 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
6168 9 November 2007: Wouter
6169 - took ldns snapshot in repo.
6170 - default config file is /etc/unbound/unbound.conf.
6171 If it doesn't exist, it is installed with the doc/example.conf file.
6172 The file is not deleted on uninstall.
6173 - default listening is not all, but localhost interfaces.
6175 8 November 2007: Wouter
6176 - Fixup chroot and drop user privileges.
6177 - new L root ip address in default hints.
6179 1 November 2007: Wouter
6180 - Fixup of crash on reload, due to anchors in env not NULLed after
6181 dealloc during deinit.
6182 - Fixup of chroot call. Happens after privileges are dropped, so
6183 that checking the passwd entry still works.
6184 - minor touch up of clear() hashtable function.
6185 - VERB_DETAIL prints out what chdir, username, chroot is being done.
6186 - when id numbers run out, caches are cleared, as in design notes.
6187 Tested with a mock setup with very few bits in id, it worked.
6188 - harden-dnssec-stripped: yes is now default. It insists on dnssec
6189 data for trust anchors. Included tests for the feature.
6191 31 October 2007: Wouter
6192 - cache-max-ttl config option.
6193 - building outside sourcedir works again.
6194 - defaults more secure:
6196 chroot: "/etc/unbound"
6197 The operator can override them to be less secure ("") if necessary.
6198 - fix horrible oversight in sorting rrset references in a message,
6199 sort per reference key pointer, not on referencepointer itself.
6200 - pidfile: "/etc/unbound/unbound.pid" is now the default.
6201 - tests changed to reflect the updated default.
6202 - created hashtable clear() function that respects locks.
6204 30 October 2007: Wouter
6205 - fixup assertion failure that relied on compressed names to be
6206 smaller than uncompressed names. A packet from comrite.com was seen
6207 to be compressed to a larger size. Added it as unit test.
6208 - quieter logging at low verbosity level for common tcp messages.
6209 - no greedy TTL update.
6211 23 October 2007: Wouter
6212 - fixup (grand-)parent problem for dnssec-lameness detection.
6213 - fixup tests to do additional section processing for lame replies,
6214 since the detection needs that.
6215 - no longer trust in query section in reply during dnssec lame detect.
6216 - dnssec lameness does not make the server never ever queried, but
6217 non-preferred. If no other servers exist or answer, the dnssec lame
6218 server is used; the fastest dnssec lame server is chosen.
6219 - added test then when trust anchor cannot be primed (nodata), the
6220 insecure mode from unbound works.
6221 - Fixup max queries per thread, any more are dropped.
6223 22 October 2007: Wouter
6224 - added donotquerylocalhost config option. Can be turned off for
6226 - ISO C compat changes.
6227 - detect RA-no-AA lameness, as LAME.
6228 - DNSSEC-lameness detection, as LAME.
6229 See notes in requirements.txt for choices made.
6230 - tests for lameness detection.
6231 - added all to make test target; need unbound for fwd tests.
6232 - testbound does not pollute /etc/unbound.
6234 19 October 2007: Wouter
6235 - added configure (and its files) to svn, so that the trunk is easier
6236 to use. ./configure, config.guess, config.sub, ltmain.sh,
6238 - added yacc/lex generated files, util/configlexer.c,
6239 util/configparser.c util/configparser.h, to svn.
6240 - without lex no attempt to use it.
6241 - unsecure response validation collated into one block.
6242 - remove warning about const cast of cfgfile name.
6243 - outgoing-interfaces can be different from service interfaces.
6244 - ldns-src configure is done during unbound configure and
6245 ldns-src make is done during unbound make, and so inherits the
6246 make arguments from the unbound make invocation.
6247 - nicer error when libevent problem causes instant exit on signal.
6248 - read root hints from a root hint file (like BIND does).
6250 18 October 2007: Wouter
6251 - addresses are logged with errors.
6252 - fixup testcode fake event to remove pending before callback
6253 since the callback may create new pending items.
6254 - tests updated because retries are now in iterator module.
6255 - ldns-testpkts code is checked for differences between unbound
6256 and ldns by makedist.sh.
6257 - ldns trunk from today added in svn repo for fallback in case
6258 no ldns is installed on the system.
6259 make download_ldns refreshes the tarball with ldns svn trunk.
6260 - ldns-src.tar.gz is used if no ldns is found on the system, and
6261 statically linked into unbound.
6262 - start of regional allocator code.
6263 - regional uses less memory and variables, simplified code.
6264 - remove of region-allocator.
6265 - alloc cache keeps a cache of recently released regional blocks,
6267 - make unit test cleanly free memory.
6269 17 October 2007: Wouter
6270 - fixup another cycle detect and ns-addr timeout resolution bug.
6271 This time by refusing delegations from the cache without addresses
6272 when resolving a mandatory-glue nameserver-address for that zone.
6273 We're going to have to ask a TLD server anyway; might as well be
6274 the TLD server for this name. And this resolves a lot of cases where
6275 the other nameserver names lead to cycles or are not available.
6276 - changed random generator from random(3) clone to arc4random wrapped
6277 for thread safety. The random generator is initialised with
6278 entropy from the system.
6279 - fix crash where failure to prime DNSKEY tried to print null pointer
6281 - removed some debug prints, only verb_algo (4) enables them.
6282 - fixup test; new random generator took new paths; such as one
6283 where no scripted answer was available.
6284 - mark insecure RRs as insecure.
6285 - fixup removal of nonsecure items from the additional.
6286 - reduced timeout values to more realistic, 376 msec (262 msec has
6287 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
6288 - server selection failover to next server after timeout (376 msec).
6290 16 October 2007: Wouter
6291 - no malloc in log_hex.
6292 - assertions around system calls.
6293 - protect against gethostname without ending zero.
6294 - ntop output is null terminated by unbound.
6295 - pidfile content null termination
6296 - various snprintf use sizeof(stringbuf) instead of fixed constant.
6297 - changed loopdetect % 8 with & 0x7 since % can become negative for
6298 weird negative input and particular interpretation of integer math.
6299 - dname_pkt_copy checks length of result, to protect result buffers.
6300 prints an error, this should not happen. Bad strings should have
6301 been rejected earlier in the program.
6302 - remove a size_t underflow from msgreply size func.
6304 15 October 2007: Wouter
6306 - fix IP6 TCP, wrong definition check. With test package.
6307 - fixup the fact that the query section was not compressed to,
6308 the code was there but was called by value instead of by reference.
6309 And test for the case, uses xxd and nc.
6310 - more portable ip6 check for sockaddr types.
6312 8 October 2007: Wouter
6313 - --disable-rpath option in configure for 64bit systems with
6314 several dynamic lib dirs.
6316 7 October 2007: Wouter
6317 - fixup tests for no AD bit in non-DO queries.
6318 - test that makes sure AD bit is not set on non-DO query.
6320 6 October 2007: Wouter
6321 - removed logfile open early. It did not have the proper permissions;
6322 it was opened as root instead of the user. And we cannot change user
6323 id yet, since chroot and bind ports need to be done.
6324 - callback checks for event callbacks done from mini_event. Because
6325 of deletions cannot do this from netevent. This means when using
6326 libevent the protection does not work on event-callbacks.
6327 - fixup too small reply (did not zero counts).
6328 - fixup reply no longer AD bit when query without DO bit.
6330 5 October 2007: Wouter
6331 - function pointer whitelist.
6333 4 October 2007: Wouter
6334 - overwrite sensitive random seed value after use.
6335 - switch to logfile very soon if not -d (console attached).
6336 - error messages do not reveal the trustanchor contents.
6337 - start work on function pointer whitelists.
6339 3 October 2007: Wouter
6340 - fix for multiple empty nonterminals, after multiple DSes in the
6342 - mesh checks if modules are looping, and stops them.
6343 - refetch with CNAMEd nameserver address regression test added.
6344 - fixup line count bug in testcode, so testbound prints correct line
6345 number with parse errors.
6346 - unit test for multiple ENT case.
6347 - fix for cname out of validated unsec zone.
6348 - fixup nasty id=0 reuse. Also added assertions to detect its
6349 return (the assertion catches in the existing test cases).
6351 1 October 2007: Wouter
6352 - skip F77, CXX, objC tests in configure step.
6353 - fixup crash in refetch glue after a CNAME.
6354 and protection against similar failures (with error print).
6356 28 September 2007: Wouter
6357 - test case for unbound-checkconf, fixed so it also checks the
6358 interface: statements.
6360 26 September 2007: Wouter
6361 - SIGHUP will reopen the log file.
6362 - Option to log to syslog.
6363 - please lint, fixup tests (that went to syslog on open, oops).
6364 - config check program.
6366 25 September 2007: Wouter
6367 - tests for NSEC3. Fixup bitmap checks for NSEC3.
6368 - positive ANY response needs to check if wildcard expansion, and
6369 check that original data did not exist.
6370 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
6371 delegation, for abuse of child zone apex nsec3.
6372 - create 0.5 release tag.
6374 24 September 2007: Wouter
6375 - do not make test programs by default.
6376 - But 'make test' will perform all of the tests.
6377 - Advertise builtin select libevent alternative when no libevent
6379 - signit can generate NSEC3 hashes, for generating tests.
6380 - multiple nsec3 parameters in message test.
6381 - too high nsec3 iterations becomes insecure test.
6383 21 September 2007: Wouter
6384 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
6385 - fixup testcode lock safety (port FreeBSD).
6386 - removes subscript has type char warnings (port Solaris 9).
6387 - fixup of field with format type to int (port MacOS/X intel).
6388 - added test for infinite loop case in nonRD answer validation.
6389 It was a more general problem, but hard to reproduce. When an
6390 unsigned rrset is being validated and the key fetched, the DS
6391 sequence is followed, but if the final name has no DS, then no
6392 proof is possible - the signature has been stripped off.
6394 20 September 2007: Wouter
6395 - fixup and test for NSEC wildcard with empty nonterminals.
6396 - makedist.sh fixup for svn info.
6397 - acl features request in plan.
6398 - improved DS empty nonterminal handling.
6399 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
6400 proof anyway, which succeeds in ANS failure case.
6401 - striplab protection in case it becomes -1.
6402 - plans for static and blacklist config.
6404 19 September 2007: Wouter
6405 - comments about non-packed usage.
6406 - plan for overload support in 0.6.
6407 - added testbound tests for a failed resolution from the logs
6408 and for failed prime when missing glue.
6409 - fixup so useless delegation points are not returned from the
6410 cache. Also the safety belt is used if priming fails to complete.
6411 - fixup NSEC rdata not to be lowercased, bind compat.
6413 18 September 2007: Wouter
6414 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
6415 - validator prints subtype classification for debug.
6417 17 September 2007: Wouter
6418 - NSEC3 hash cache unit test.
6419 - validator nsec3 nameerror test.
6421 14 September 2007: Wouter
6422 - nsec3 nodata proof, nods proof, wildcard proof.
6423 - nsec3 support for cname chain ending in noerror or nodata.
6424 - validator calls nsec3 proof routines if no NSECs prove anything.
6425 - fixup iterator bug where it stored the answer to a cname under
6426 the wrong qname into the cache. When prepending the cnames, the
6427 qname has to be reset to the original qname.
6429 13 September 2007: Wouter
6430 - nsec3 find matching and covering, ce proof, prove namerror msg.
6432 12 September 2007: Wouter
6433 - fixup of manual page warnings, like for NSD bugreport.
6434 - nsec3 work, config, max iterations, filter, and hash cache.
6436 6 September 2007: Wouter
6437 - fixup to find libevent on mac port install.
6438 - fixup size_t vs unsigned portability in validator/sigcrypt.
6439 - please compiler on different platforms, for unreachable code.
6441 - pthread_rwlock type is optional, in case of old pthread libs.
6443 5 September 2007: Wouter
6444 - cname, name error validator tests.
6445 - logging of qtype ANY works.
6446 - ANY type answers get RRSIG in answer section of replies (but not
6447 in other sections, unless DO bit is on).
6448 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
6449 - DS and noDS referral validation test.
6450 - if you configure many trust anchors, parent trust anchors can
6451 securely deny existence of child trust anchors, if validated.
6452 - not all *.name NSECs are present because a wildcard was matched,
6453 and *.name NSECs can prove nodata for empty nonterminals.
6454 Also, for wildcard name NSECs, check they are not from the parent
6455 zone (for wildcarded zone cuts), and check absence of CNAME bit,
6457 - configure option for memory allocation debugging.
6458 - port configure option for memory allocation to solaris10.
6460 4 September 2007: Wouter
6461 - fixup of Leakage warning when serviced queries processed multiple
6462 callbacks for the same query from the same server.
6463 - testbound removes config file from /tmp on failed exit.
6464 - fixup for referral cleanup of the additional section.
6465 - tests for cname, referral validation.
6466 - neater testbound tpkg output.
6467 - DNAMEs no longer match their apex when synthesized from the cache.
6468 - find correct signer name for DNAME responses.
6469 - wildcarded DNAME test and fixup code to detect.
6470 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
6471 So that wildcarded CNAMEs get their NSEC with them to the answer.
6472 - test for a CNAME to a DNAME to a CNAME to an answer, all from
6473 different domains, for key fetching and signature checking of
6476 3 September 2007: Wouter
6477 - Fixed error in iterator that would cause assertion failure in
6478 validator. CNAME to a NXDOMAIN response was collated into a response
6479 with both a CNAME and the NXDOMAIN rcode. Added a test that the
6480 rcode is changed to NOERROR (because of the CNAME).
6481 - timeout on tcp does not lead to spurious leakage detect.
6482 - account memory for name of lame zones, so that memory leakages does
6483 not show lame cache growth as a leakage growth.
6484 - config setting for lameness cache expressed in bytes, instead of
6486 - tool too summarize allocations per code line.
6488 31 August 2007: Wouter
6489 - can read bind trusted-keys { ... }; files, in a compatibility mode.
6490 - iterator should not detach target queries that it still could need.
6491 the protection against multiple outstanding queries is moved to a
6492 current_query num check.
6493 - validator nodata, positive, referral tests.
6494 - dname print can print '*' wildcard.
6496 30 August 2007: Wouter
6497 - fixup override date config option.
6498 - config options to control memory usage.
6499 - caught bad free of un-alloced data in worker_send error case.
6500 - memory accounting for key cache (trust anchors and temporary cache).
6501 - memory accounting fixup for outside network tcp pending waits.
6502 - memory accounting fixup for outside network tcp callbacks.
6503 - memory accounting for iterator fixed storage.
6504 - key cache size and slabs config options.
6505 - lib crypto cleanups at exit.
6507 29 August 2007: Wouter
6508 - test tool to sign rrsets for testing validator with.
6509 - added RSA and DSA test keys, public and private pairs, 512 bits.
6510 - default configuration is with validation enabled.
6511 Only a trust-anchor needs to be configured for DNSSEC to work.
6512 - do not convert to DER for DSA signature verification.
6513 - validator replay test file, for a DS to DNSKEY DSA key prime and
6516 28 August 2007: Wouter
6517 - removed double use for udp buffers, that could fail,
6518 instead performs a malloc to do the backup.
6519 - validator validates referral messages, by validating all the rrsets
6520 and stores the rrsets in the cache. Further referral (nonRD queries)
6521 replies are made from the rrset cache directly. Unless unchecked
6522 rrsets are encountered, there are then validated.
6523 - enforce that signing is done by a parent domain (or same domain).
6524 - adjust TTL downwards if rrset TTL bigger than signature allows.
6525 - permissive mode feature, sets AD bit for secure, but bogus does
6526 not give servfail (bogus is changed into indeterminate).
6527 - optimization of rrset verification. rr canonical sorting is reused,
6528 for the same rrset. canonical rrset image in buffer is reused for
6530 - if the rrset is too big (64k exactly + large owner name) the
6531 canonicalization routine will fail if it does not fit in buffer.
6532 - faster verification for large sigsets.
6533 - verb_detail mode reports validation failures, but not the entire
6534 algorithm for validation. Key prime failures are reported as
6537 27 August 2007: Wouter
6538 - do not garble the edns if a cache answer fails.
6539 - answer norecursive from cache if possible.
6540 - honor clean_additional setting when returning secure non-recursive
6542 - do not store referral in msg cache for nonRD queries.
6543 - store verification status in the rrset cache to speed up future
6545 - mark rrsets indeterminate and insecure if they are found to be so.
6546 and store this in the cache.
6548 24 August 2007: Wouter
6549 - message is bogus if unsecure authority rrsets are present.
6550 - val-clean-additional option, so you can turn it off.
6551 - move rrset verification out of the specific proof types into one
6552 routine. This makes the proof routines prettier.
6553 - fixup cname handling in validator, cname-to-positive and cname-to-
6555 - Do not synthesize DNSKEY and DS responses from the rrset cache if
6556 the rrset is from the additional section. Signatures may have
6557 fallen off the packet, and cause validation failure.
6558 - more verbose signature date errors (with the date attached).
6559 - increased default infrastructure cache size. It is important for
6560 performance, and 1000 entries are only 212k (or a 400 k total cache
6561 size). To 10000 entries (for 2M entries, 4M cache size).
6563 23 August 2007: Wouter
6564 - CNAME handling - move needs_validation to before val_new().
6565 val_new() setups the chase-reply to be an edited copy of the msg.
6566 new classification, and find signer can find for it.
6567 removal of unsigned crap from additional, and query restart for
6569 - refuse to follow wildcarded DNAMEs when validating.
6570 But you can query for qtype ANY, or qtype DNAME and validate that.
6572 22 August 2007: Wouter
6574 - review - use val_error().
6576 21 August 2007: Wouter
6577 - ANY response validation.
6578 - store security status in cache.
6579 - check cache security status and either send the query to be
6580 validated, return the query to client, or send servfail to client.
6581 Sets AD bit on validated replies.
6582 - do not examine security status on an error reply in mesh_done.
6583 - construct DS, DNSKEY messages from rrset cache.
6584 - manual page entry for override-date.
6586 20 August 2007: Wouter
6587 - validate and positive validation, positive wildcard NSEC validation.
6588 - nodata validation, nxdomain validation.
6590 18 August 2007: Wouter
6591 - process DNSKEY response in FINDKEY state.
6593 17 August 2007: Wouter
6594 - work on DS2KE routine.
6595 - val_nsec.c for validator NSEC proofs.
6596 - unit test for NSEC bitmap reading.
6597 - dname iswild and canonical_compare with unit tests.
6599 16 August 2007: Wouter
6601 - latest release libevent 1.3c and 1.3d have threading fixed.
6602 - key entry fixup data pointer and ttl absolute.
6603 - This makes a key-prime succeed in validator, with DS or DNSKEY as
6605 - fixup canonical compare byfield routine, fix bug and also neater.
6606 - fixed iterator response type classification for queries of type
6608 dig ANY gives sometimes NS rrset in AN and NS section, and parser
6609 removes the NS section duplicate. dig NS gives sometimes the NS
6610 in the answer section, as referral.
6611 - validator FINDKEY state.
6613 15 August 2007: Wouter
6614 - crypto calls to verify signatures.
6615 - unit test for rrsig verification.
6617 14 August 2007: Wouter
6618 - default outgoing ports changed to avoid port 2049 by default.
6619 This port is widely blocked by firewalls.
6620 - count infra lameness cache in memory size.
6621 - accounting of memory improved
6622 - outbound entries are allocated in the query region they are for.
6623 - extensive debugging for memory allocations.
6624 - --enable-lock-checks can be used to enable lock checking.
6625 - protect undefs in config.h from autoheaders ministrations.
6626 - print all received udp packets. log hex will print on multiple
6628 - fixed error in parser with backwards rrsig references.
6629 - mark cycle targets for iterator did not have CD flag so failed
6632 13 August 2007: Wouter
6633 - fixup makefile, if lexer is missing give nice error and do not
6634 mess up the dependencies.
6635 - canonical compare routine updated.
6636 - canonical hinfo compare.
6637 - printout list of the queries that the mesh is working on.
6639 10 August 2007: Wouter
6640 - malloc and free overrides that track total allocation and frees.
6641 for memory debugging.
6642 - work on canonical sort.
6644 9 August 2007: Wouter
6645 - canonicalization, signature checks
6646 - dname signature label count and unit test.
6647 - added debug heap size print to memory printout.
6648 - typo fixup in worker.c
6649 - -R needed on solaris.
6650 - validator override option for date check testing.
6652 8 August 2007: Wouter
6653 - ldns _raw routines created (in ldns trunk).
6654 - sigcrypt DS digest routines
6655 - val_utils uses sigcrypt to perform signature cryptography.
6656 - sigcrypt keyset processing
6658 7 August 2007: Wouter
6659 - security status type.
6660 - security status is copied when rdata is equal for rrsets.
6661 - rrset id is updated to invalidate all the message cache entries
6662 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
6664 - val_sigcrypt file for validator signature checks.
6666 6 August 2007: Wouter
6667 - key cache for validator.
6668 - moved isroot and dellabel to own dname routines, with unit test.
6670 3 August 2007: Wouter
6672 - scrubber check section of lame NS set.
6673 - trust anchors can be in config file or read from zone file,
6674 DS and DNSKEY entries.
6675 - unit test trust anchor storage.
6676 - trust anchors converted to packed rrsets.
6677 - key entry definition.
6679 2 August 2007: Wouter
6680 - configure change for latest libevent trunk version (needs -lrt).
6681 - query_done and walk_supers are moved out of module interface.
6682 - fixup delegation point duplicates.
6683 - fixup iterator scrubber; lame NS set is let through the scrubber
6684 so that the classification is lame.
6685 - validator module exists, and does nothing but pass through,
6686 with calling of next module and return.
6689 1 August 2007: Wouter
6690 - set version to 0.5
6691 - module work for module to module interconnections.
6692 - config of modules.
6693 - detect cycle takes flags.
6695 31 July 2007: Wouter
6699 30 July 2007: Wouter
6700 - changed random state init, so that sequential process IDs are not
6701 cancelled out by sequential thread-ids in the random number seed.
6702 - the fwd_three test, which sends three queries to unbound, and
6703 unbound is kept waiting by ldns-testns for 3 seconds, failed
6704 because the retry timeout for default by unbound is 3 seconds too,
6705 it would hit that timeout and fail the test. Changed so that unbound
6706 is kept waiting for 2 seconds instead.
6708 27 July 2007: Wouter
6709 - removed useless -C debug option. It did not work.
6710 - text edit of documentation.
6711 - added doc/CREDITS file, referred to by the manpages.
6714 26 July 2007: Wouter
6715 - cycle detection, for query state dependencies. Will attempt to
6716 circumvent the cycle, but if no other targets available fails.
6717 - unit test for AXFR, IXFR response.
6718 - test for cycle detection.
6720 25 July 2007: Wouter
6721 - testbound read ADDRESS and check it.
6722 - test for version.bind and friends.
6723 - test for iterator chaining through several referrals.
6724 - test and fixup for refetch for glue. Refetch fails if glue
6725 is still not provided.
6727 24 July 2007: Wouter
6728 - Example section in config manual.
6729 - Addr stored for range and moment in replay.
6731 20 July 2007: Wouter
6732 - Check CNAME chain before returning cache entry with CNAMEs.
6733 - Option harden-glue, default is on. It will discard out of zone
6734 data. If disabled, performance is faster, but spoofing attempts
6735 become a possibility. Note that still normalize scrubbing is done,
6736 and that the potentially spoofed data is used for infrastructure
6737 and not returned to the client.
6738 - if glue times out, refetch by asking parent of delegation again.
6739 Much like asking for DS at the parent side.
6740 - TODO items from forgery-resilience draft.
6741 and on memory handling improvements.
6742 - renamed module_event_timeout to module_event_noreply.
6743 - memory reporting code; reports on memory usage after handling
6744 a network packet (not on cache replies).
6746 19 July 2007: Wouter
6747 - shuffle NS selection when getting nameserver target addresses.
6748 - fixup of deadlock warnings, yield cpu in checklock code so that
6749 freebsd scheduler selects correct process to run.
6750 - added identity and version config options and replies.
6751 - store cname messages complete answers.
6753 18 July 2007: Wouter
6754 - do not query addresses, 127.0.0.1, and ::1 by default.
6756 17 July 2007: Wouter
6757 - forward zone options in config file.
6758 - forward per zone in iterator. takes precedence over stubs.
6759 - fixup commithooks.
6760 - removed forward-to and forward-to-port features, subsumed by
6762 - fix parser to handle absent server: clause.
6763 - change untrusted rrset test to account for scrubber that is now
6764 applied during the test (which removes the poison, by the way).
6765 - feature, addresses can be specified with @portnumber, like nsd.conf.
6766 - test config files changed over to new forwarder syntax.
6768 27 June 2007: Wouter
6769 - delete of mesh does a postorder traverse of the tree.
6770 - found and fixed a memory leak. For TTL=0 messages, that would
6771 not be cached, instead the msg-replyinfo structure was leaked.
6772 - changed server selection so it will filter out hosts that are
6773 unresponsive. This is defined as a host with the maximum rto value.
6774 This means that unbound tried the host for retries up to 120 secs.
6775 The rto value will time out after host-ttl seconds from the cache.
6776 This keeps such unresolvable queries from taking up resources.
6777 - utility for keeping histogram.
6779 26 June 2007: Wouter
6780 - mesh is called by worker, and iterator uses it.
6781 This removes the hierarchical code.
6782 QueryTargets state and Finished state are merged for iterator.
6783 - forwarder mode no longer sets AA bit on first reply.
6784 - rcode in walk_supers is not needed.
6786 25 June 2007: Wouter
6788 - error encode routine for ease.
6790 22 June 2007: Wouter
6791 - removed unused _node iterator value from rbtree_t. Takes up space.
6792 - iterator can handle querytargets state without a delegation point
6793 set, so that a priming(stub) subquery error can be handled.
6794 - iterator stores if it is priming or not.
6795 - log_query_info() neater logging.
6796 - changed iterator so that it does not alter module_qstate.qinfo
6797 but keeps a chase query info. Also query_flags are not altered,
6798 the iterator uses chase_flags.
6799 - fixup crash in case no ports for the family exist.
6801 21 June 2007: Wouter
6802 - Fixup secondary buffer in case of error callback.
6803 - cleanup slumber list of runnable states.
6804 - module_subreq_depth fails to work in slumber list.
6805 - fixup query release for cached results to sub targets.
6806 - neater error for tcp connection failure, shows addr in verbose.
6807 - rbtree_init so that it can be used with preallocated memory.
6809 20 June 2007: Wouter
6810 - new -C option to enable coredumps after forking away.
6812 - fixup CNAME generation by scrubber, and memory allocation of it.
6813 - fixup deletion of serviced queries when all callbacks delete too.
6814 - set num target queries to 0 when you move them to slumber list.
6815 - typo in check caused subquery errors to be ignored, fixed.
6816 - make lint happy about rlim_t.
6817 - freeup of modules after freeup of module-states.
6818 - duplicate replies work, this uses secondary udp buffer in outnet.
6820 19 June 2007: Wouter
6821 - nicer layout in stats.c, review 0.3 change.
6822 - spelling improvement, review 0.3 change.
6823 - uncapped timeout for server selection, so that very fast or slow
6824 servers will stand out from the rest.
6825 - target-fetch-policy: "3 2 1 0 0" config setting.
6826 - fixup queries answered without RD bit (for root prime results).
6827 - refuse AXFR and IXFR requests.
6828 - fixup RD flag in error reply from iterator. fixup RA flag from
6830 - fixup encoding of very short edns buffer sizes, now sets TC bit.
6831 - config options harden-short-bufsize and harden-large-queries.
6833 18 June 2007: Wouter
6834 - same, move subqueries to slumber list when first has resolved.
6835 - fixup last fix for duplicate callbacks.
6836 - another offbyone in targetcounter. Also in Java prototype by the way.
6838 15 June 2007: Wouter
6839 - if a query asks to be notified of the same serviced query result
6840 multiple times, this will succeed. Only one callback will happen;
6841 multiple outbound-list entries result (but the double cleanup of it
6843 - when iterator moves on due to CNAME or referral, it will remove
6844 the subqueries (for other targets). These are put on the slumber
6846 - state module wait subq is OK with no new subqs, an old one may have
6847 stopped, with an error, and it is still waiting for other ones.
6848 - if a query loops, halt entire query (easy way to clean up properly).
6850 14 June 2007: Wouter
6851 - num query targets was > 0 , not >= 0 compared, so that fetch
6852 policy of 0 did nothing.
6854 13 June 2007: Wouter
6855 - debug option: configure --enable-static-exe for compile where
6856 ldns and libevent are linked statically. Default is off.
6857 - make install and make uninstall. Works with static-exe and without.
6858 installation of unbound binary and manual pages.
6859 - alignment problem fix on solaris 64.
6860 - fixup address in case of TCP error.
6862 12 June 2007: Wouter
6863 - num target queries was set to 0 at a bad time. Default it to 0 and
6864 increase as target queries are done.
6865 - synthesize CNAME and DNAME responses from the cache.
6866 - Updated doxygen config for doxygen 1.5.
6867 - aclocal newer version.
6868 - doxygen 1.5 fixes for comments (for the strict check on docs).
6870 11 June 2007: Wouter
6871 - replies on TCP queries have the address field set in replyinfo,
6872 for serviced queries, because the initiator does not know that
6873 a TCP fallback has occured.
6874 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
6875 if qtype directly queries for the type (and then only show that
6876 'unknown type' in the answer section).
6877 - fixed message parsing where rrsigs on their own would be put
6878 in the signature list over the rrsig type.
6881 - fixup error in double linked list insertion for subqueries and
6882 for outbound list of serviced queries for iterator module.
6883 - nicer printout of outgoing port selection.
6884 - fixup cname target readout.
6885 - nicer debug output.
6886 - fixup rrset counts when prepending CNAMEs to the answer.
6887 - fixup rrset TTL for prepended CNAMEs.
6888 - process better check for looping modules, and which submodule to
6890 - subreq insertion code fixup for slumber list.
6891 - VERB_DETAIL, verbosity: 2 level gives short but readable output.
6892 VERB_ALGO, verbosity: 3 gives extensive output.
6893 - fixup RA bit in cached replies.
6894 - fixup CNAME responses from the cache no longer partial response.
6895 - error in network send handled without leakage.
6896 - enable ip6 from config, and try ip6 addresses if available,
6897 if ip6 is not connected, skips to next server.
6900 - iterator state finished.
6901 - subrequests without parent store in cache and stop.
6902 - worker slumber list for ongoing promiscuous queries.

6905 - priming gives LAME result, returns SERVFAIL.
6906 - debug routine to print dns_msg as handled by iterator.
6907 - memleak in config file stubs fixup.
6908 - more small bugs, in scrubber, query compare no ID for lookup,
6909 in dname validation for NS targets.
6910 - sets entry.key for new special allocs.
6911 - lognametypeclass can display unknown types and classes.
6914 - random selection of equally preferred nameserver targets.
6915 - reply info copy routine. Reuses existing code.
6916 - cache lameness in response handling.
6917 - do not touch qstate after worker_process_query because it may have
6918 been deleted by that routine.
6919 - Prime response state.
6920 - Process target response state.
6921 - some memcmp changed to dname_compare for case preservation.
6924 - normalize incoming messages. Like unbound-java, with CNAME chain
6925 checked, DNAME checked, CNAME's synthesized, glue checked.
6926 - sanitize incoming messages.
6927 - split msgreply encode functions into own file msgencode.c.
6928 - msg_parse to queryinfo/replyinfo conversion more versatile.
6929 - process_response, classify response, delegpt_from_message.
6932 - querytargets state.
6933 - dname_subdomain_c() routine.
6934 - server selection, based on RTT. ip6 is filtered out if not available,
6935 and lameness is checked too.
6936 - delegation point copy routine.
6939 - removed FLAG_CD from message and rrset caches. This was useful for
6940 an agnostic forwarder, but not for a sophisticated (trust value per
6941 rrset enabled) cache.
6942 - iterator response typing.
6943 - iterator cname handle.
6944 - iterator prime start.
6946 - processInitRequest and processInitRequest2.
6947 - cache synthesizes referral messages, with DS and NSEC.

6956 - 'qnamesize' changed to 'qname_len' for similar naming scheme.
6959 - Acknowledge use of unbound-java code in iterator. Nicer readme.
6960 - services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
6961 rrset cache from module environment.
6962 - packed rrset key has type and class as easily accessible struct
6963 members. They are still kept in network format for fast msg encode.
6964 - dns cache find_delegation routine.
6965 - iterator main functions setup.
6966 - dns cache lookup setup.
6969 - small changes to prepare for subqueries.
6970 - iterator forwarder feature separated out.
6971 - iterator hints stub code, config file stub code, so that first
6972 testing can proceed locally.
6973 - replay tests now have config option to enable forwarding mode.
6976 - outside network does precise timers for roundtrip estimates for rtt
6977 and for setting timeout for UDP. Pending_udp takes milliseconds.
6978 - cleaner iterator sockaddr conversion of forwarder address.
6979 - iterator/iter_utils and iter_delegpt setup.
6983 - outbound query list for modules and support to callback with the
6984 outbound entry to the module.
6985 - testbound support for new serviced queries.
6986 - test for retry to TCP cannot use testbound any longer.
6987 - testns test for EDNS fallback, test for TCP fallback already exists.
6988 - fixes for no-locking compile.
6989 - mini_event timer precision and fix for change in timeouts during
6990 timeout callback. Fix for fwd_three tests, performed nonexit query.
6993 - small comment on hash table locking.
6994 - outside network serviced queries, contain edns and tcp fallback,
6995 and udp retries and rtt timing.

7043 - EDNS read from query, used to make reply smaller.
7044 - advertised edns value constants.
7045 - EDNS BADVERS response, if asked for too high edns version.
7046 - EDNS extended error responses once the EDNS record from the query
7047 has successfully been parsed.
7050 - msgreply sizefunc is more accurate.

7052 - hashtable insert takes argument so that a thread can use its own
7053 alloc cache to store released keys.
7054 - alloc cache special_release() locks if necessary.
7055 - rrset trustworthiness type added.
7056 - thread keeps a scratchpad region for handling messages.

7065 - fill refs. Use new parse and encode to answer queries.
7066 - stores rrsets in cache.
7067 - uses new msgreply format in cache.
7070 - dname unit tests in own file and spread out neatly in functions.
7071 - more dname unit tests.
7072 - message encoding creates truncated TC flagged messages if they do
7073 not fit, and will leave out (whole)rrsets from additional if needed.
7076 - decompress query section, extremely lenient acceptance.
7077 But only for answers from other servers, not for plain queries.
7078 - compression and decompression test cases.
7080 - example.conf interface: line is changed from 127.0.0.1 which leads
7081 to problems if used (restricting communication to the localhost),
7082 to a documentation and test address.
7084 27 April 2007: Wouter

7143 - following a small change in LDNS, parsing code calculates the
7144 memory size to allocate for rrs.
7145 - code to handle ID creation.
7147 13 April 2007: Wouter
7148 - parse routines. Code that parses rrsets, rrs.

7151 - dname compare routine that preserves case, with unit tests.
7153 11 April 2007: Wouter
7154 - parse work - dname packet parse, msgparse, querysection parse,
7155 start of sectionparse.
7157 10 April 2007: Wouter
7158 - Improved alignment of reply_info packet, nice for 32 and 64 bit.

7175 3 April 2007: Wouter
7176 - detect sign of msghdr.msg_iovlen so that the cast to that type
7177 in netevent (which is there to please lint) can be correct.
7178 The type on several OSes ranges from int, int32, uint32, size_t.
7179 Detects unsigned or signed using math trick.

7200 - do not do useless byteswap on query id. Store reply flags in uint16
7201 for easier access (and no repeated byteswapping).
7203 - configure detects and config.h includes sys/uio.h for writev decl.
7205 28 March 2007: Wouter
7206 - new config option: num-queries-per-thread.
7207 - added tpkg test for answering three queries at the same time
7208 using one thread (from the query service list).
7210 27 March 2007: Wouter
7211 - added test for cache and not cached answers, in testbound replays.
7212 - testbound can give config file and commandline options from the
7213 replay file to unbound.
7214 - created test that checks if items drop out of the cache.
7215 - added word 'partitioned hash table' to documentation on slab hash.
7216 A slab hash is a partitioned hash table.
7217 - worker can handle multiple queries at a time.
7219 26 March 2007: Wouter
7220 - config settings for slab hash message cache.
7221 - test for cached answer.
7222 - Fixup deleting fake answer from testbound list.
7224 23 March 2007: Wouter
7225 - review of yesterday's commits.
7226 - covered up memory leak of the entry locks.
7227 - answers from the cache correctly. Copies flags correctly.
7228 - sanity check for incoming query replies.
7229 - slabbed hash table. Much nicer contention, need dual cpu to see.
7231 22 March 2007: Wouter
7232 - AIX configure check.
7233 - lock-verify can handle references to locks that are created
7234 in files it has not yet read in.
7235 - threaded hash table test.
7236 - unit test runs lock-verify afterwards and checks result.
7237 - need writelock to update data on hash_insert.
7238 - message cache code, msgreply code.
7240 21 March 2007: Wouter
7241 - unit test of hash table, fixup locking problem in table_grow().
7242 - fixup accounting of sizes for removing items from hashtable.
7243 - unit test for hash table, single threaded test of integrity.
7244 - lock-verify reports errors nicely. More quiet in operation.
7246 16 March 2007: Wouter
7247 - lock-verifier, checks consistent order of locking.
7249 14 March 2007: Wouter
7250 - hash table insert (and subroutines) and lookup implemented.

7256 - util/storage/lruhash.h for LRU hash table structure.
7258 12 March 2007: Wouter
7259 - configure.ac moved to 0.2.
7260 - query_info and replymsg util/data structure.
7262 9 March 2007: Wouter
7263 - added rwlock writelock checking.
7264 So it will keep track of the writelock, and readlocks are enforced
7265 to not change protected memory areas.
7266 - log_hex function to dump hex strings to the logfile.
7267 - checklocks zeroes its destroyed lock after checking memory areas.
7268 - unit test for alloc.
7269 - identifier for union in checklocks to please older compilers.
7272 8 March 2007: Wouter
7273 - Reviewed checklock code.
7275 7 March 2007: Wouter
7276 - created a wrapper around thread calls that performs some basic
7277 checking for data race and deadlock, and basic performance
7278 contention measurement.
7280 6 March 2007: Wouter
7281 - Testbed works with threading (different machines, different options).
7282 - alloc work, does the special type.
7284 2 March 2007: Wouter
7285 - do not compile fork funcs unless needed. Otherwise will give
7286 type errors as their typedefs have not been enabled.
7287 - log shows thread numbers much more nicely (and portably).
7288 - even on systems with nonthreadsafe libevent signal handling,
7289 unbound will exit if given a signal.
7290 Reloads will not work, and exit is not graceful.
7291 - start of alloc framework layout.
7293 1 March 2007: Wouter
7294 - Signals, libevent and threads work well, with libevent patch and
7295 changes to code (close after event_del).
7296 - set ipc pipes nonblocking.
7298 27 February 2007: Wouter
7299 - ub_thread_join portable definition.
7300 - forking is used if no threading is available.
7301 Tested, it works, since pipes work across processes as well.
7302 Thread_join is replaced with waitpid.
7303 - During reloads the daemon will temporarily handle signals,
7304 so that they do not result in problems.
7305 - Also randomize the outgoing port range for tests.
7306 - If query list is full, will stop selecting listening ports for read.
7307 This makes all threads service incoming requests, instead of one.
7308 No memory is leaking during reloads, service of queries, etc.
7309 - test that uses ldns-testns -f to test threading. Have to answer
7310 three queries at the same time.
7311 - with verbose=0 operates quietly.
7313 26 February 2007: Wouter
7314 - ub_random code used to select ID and port.
7315 - log code prints thread id.
7316 - unbound can thread itself, with reload(HUP) and quit working
7318 - don't open pipes for #0, doesn't need it.
7319 - listens to SIGTERM, SIGQUIT, SIGINT (all quit) and SIGHUP (reload).
7321 23 February 2007: Wouter
7322 - Can do reloads on sigHUP. Everything is stopped, and freed,
7323 except the listening ports. Then the config file is reread.
7324 And everything is started again (and listening ports if needed).
7325 - Ports for queries are shared.
7326 - config file added interface:, chroot: and username:.
7327 - config file: directory, logfile, pidfile. And they work too.
7328 - will daemonize by default now. Use -d to stay in the foreground.
7329 - got BSD random[256 state] code, made it threadsafe. util/random.
7331 22 February 2007: Wouter
7332 - Have a config file. Removed commandline options, moved to config.

7344 - put include errno.h in config.h
7346 19 February 2007: Wouter
7347 - Created 0.0 svn tag.
7348 - added acx_pthread.m4 autoconf check for pthreads from
7349 the autoconf archive. It is GPL-with-autoconf-exception Licensed.

7352 16 February 2007: Wouter
7353 - Updated testbed script, works better by using make on remote end.
7354 - removed check decls, we can compile without them.
7355 - makefile supports LIBOBJ replacements.
7356 - docs checks ignore compat code.
7357 - added util/mini-event.c and .h, a select based alternative used with
7358 ./configure --with-libevent=no
7359 It is limited to 1024 file descriptors, and has less features.
7360 - will not create ip6 sockets if ip6 not on the machine.
7362 15 February 2007: Wouter
7363 - port to FreeBSD 4.11 Dec Alpha. Also works on Solaris 10 sparc64,
7364 Solaris 9, FreeBSD 6, Linux i386 and OSX powerpc.
7365 - malloc rndstate, so that it is aligned for access.
7366 - fixed rbtree cleanup with postorder traverse.
7367 - fixed pending messages are deleted when handled.
7368 - You can control verbosity; default is not verbose, every -v
7369 adds more verbosity.
7371 14 February 2007: Wouter
7372 - Included configure.ac changes from ldns.
7373 - detect (some) headers before the standards check.
7374 - do not use isblank to test c99, since its not available on solaris9.
7375 - review of testcode.
7376 * entries in a RANGE are no longer reversed.
7377 * print name of file with replay entry parse errors.
7378 - port to OSX: cast to int for some prints of sizet.
7379 - Makefile copies ldnstestpkts.c before doing dependencies on it.
7381 13 February 2007: Wouter

7393 and main structure of event replay routines.
7395 8 February 2007: Wouter
7398 - testcode/fake_event work.
7400 7 February 2007: Wouter
7401 - return answer with the same ID as query was sent with.
7402 - created udp forwarder test. I've done some effort to make it perform
7403 quickly. After servers are created, no big sleep statements but
7404 it checks the logfiles to see if servers have come up. Takes 0.14s.
7405 - set addrlen value when calling recvfrom.
7406 - comparison of addrs more portable.
