- Update to 1.21.0:
Security Fixes:
* Merge #1073: fix null pointer dereference issue in function
ub_ctx_set_fwd.
[CVE-2024-43167, bsc#1229068]
Features:
* Fix #1071: [FR] Clear both in-memory and cachedb module cache
with `unbound-control flush*` commands.
* Fix #144: Port ipset to BSD pf tables.
* Add dnstap-sample-rate that logs only 1/N messages, for high
volume server environments. Thanks Dan Luther.
* Add root key 38696 from 2024 for DNSSEC validation. It is added
to the default root keys in unbound-anchor. The content can be
inspected with `unbound-anchor -l`.
* Merge #1090: Cookie secret file. Adds `cookie-secret-file:
"unbound_cookiesecrets.txt"` option to store cookie secrets for
EDNS COOKIE secret rollover. The remote control
add_cookie_secret, activate_cookie_secret and
drop_cookie_secret commands can be used for rollover, the
command print_cookie_secrets shows the values in use.
Bug Fixes:
* Fix CAMP issues with global quota. Thanks to Huayi
Duan, Marco Bearzi, Jodok Vieli, and Cagin Tanir from NetSec
group, ETH Zurich.
* Fix CacheFlush issues with limit on NS RRs. Thanks to Yehuda
Afek, Anat Bremler-Barr, Shoham Danino and Yuval Shavitt
(Tel-Aviv University and Reichman University).
* Merge #1062: Fix potential overflow bug while parsing port in
function cfg_mark_ports.
* Fix for #1062: declaration before statement, avoid print of
null, and redundant check for array size.
* Fix to squelch udp connect errors in the log at low verbosity
about invalid argument for IPv6 link local addresses.
* Fix when the mesh jostle is exceeded that nameserver targets
are marked as resolved, so that the lookup is not stuck on the
requestlist.
* Add missing common functions to tdir tests.
* Merge #1070: Fix rtt assignement for low values of
infra-cache-max-rtt.
* Merge #1069: Fix unbound-control stdin commands for
multi-process Unbounds.
* Fix unbound-control commands that read stdin in multi-process
operation (local_zones_remove, local_zones, local_datas_remove,
local_datas, view_local_datas_remove, view_local_datas). They
will be properly distributed to all processes. dump_cache and
load_cache are no longer supported in multi-process operation.
* Remove testdata/remote-threaded.tdir.
testdata/09-unbound-control.tdir now checks both single and
multi process/thread operation.
* Fix to print a parse error when config is read with no name for
a forward-zone, stub-zone or view.
* Fix for parse end of forward-zone, stub-zone and view.
* Fix for #1064: Fix that cachedb expired messages are considered
insecure, and thus can be served to clients when dnssec is
enabled.
* Fix #1059: Intermittent DNS blocking failure with local-zone
and always_nxdomain. Addition of local_zones dynamically via
unbound-control was not finding the zone's parent correctly.
* Fix #1064: Unbound 1.20 Cachedb broken?

support.
* unbound-control-setup: check openssl availability before doing
anything, patch from Michael Tokarev.
* Update patch to remove 'command' shell builtin and update error
text.
* Fix to enable that SERVFAIL is cached, for a short period, for
more cases. In the cases where limits are exceeded.

* Fix #1079: tags from tagged rpz zones are no longer honored
after upgrade from 1.19.3 to 1.20.0.
* Fix for #1079: fix RPZ taglist in iterator callback that no
client info is like no taglist intersection.

memory leak fixes.
* Fix memory leak when reload_keep_cache is used and num-threads
changes.
* Fix memory leak on exit for unbound-dnstap-socket; creates
false negatives during testing.
* Fix memory leak in setup of dsa sig.
* Fix typos for 'the the' in text.
* Fix validation for repeated use of a DNAME record.
* Add unit test for validation of repeated use of a DNAME record.
* Fix #1091: Build fails with OpenSSL >= 3.0 built with
OPENSSL_NO_DEPRECATED.

by adding helpful text for the Python interpreter version and
allowing the default pkg-config unavailability error message to
be shown.
* Fix pkg-config availability check in dnstap/dnstap.m4 and
systemd.m4.
* Explicitly set the RD bit for the mesh query flags when
prefetching. These queries have no waiting client but they need
to be treated as recursive.
* Fix ip-ratelimit-cookie setting, it was not applied.
* Fix to remove unused include from the readzone test program.
* Fix unused variable warning in do_cache_remove.
* Fix compile warning in worker pthread id printout.

* Fix to use modstack_init in zonemd unit test.
* Fix to remove unneeded linebreak in fptr_wlist.c.
* Fix compile warnings in fptr_wlist.c.
* Fix for repeated use of a DNAME record: first overallocate and
then move the exact size of the init value to avoid false
positive heap overflow reads from address sanitizers.
* Fix to print details about the failure to lookup a DNSKEY
record when validation fails due to the missing DNSKEY. Also
for key prime and DS lookups.
* Fix for neater printout for error for missing DS response.
* Fix neater printout.
* Fix #1099: Unbound core dump on SIGSEGV.
* Fix for #1099: Fix to check for deleted RRset when the contents
is updated and fetched after it is stored, and also check for a
changed RRset.
* Don't check for message TTL changes if the RRsets remain the
same.
* Fix that validation reason failure that uses string print uses
separate buffer that is passed, from the scratch validation
buffer.
* Fixup algo_needs_reason string buffer length.
* Fix shadowed error string variable in validator dnskey
handling.
* Update list of known EDE codes.
* For #773: In contrib/unbound.service.in set unbound to start
after network-online.target. Also for
contrib/unbound_portable.service.in.
* Fix #1103: unbound 1.20.0 segmentation fault with nghttp2.
* For #1103: fix to also drop mesh state reference when a h2
reply is dropped.
* Add RPZ tag tests in acl_interface.tdir.
* For #1102: clearer text for using interface-* options for the
loopback interface.
* For #1103: fix to also drop mesh state reference when the
discard limit is reached, when there is an error making a new
recursion state and when the connection is dropped with
is_drop.
* For #1103: Fix to drop mesh state reference for the http2
stream associated with the reply, not the currently active
stream. And it does not remove it twice on a mesh_send_reply
call. The reply h2_stream is NULL when not in use, for more
initialisation.
* Fix dnstap wakeup, a running wakeup timer is left to expire and
not increased, a timer is started when the dtio thread is
sleeping, the timer set disabled when the dtio thread goes to
sleep, and after sleep the thread checks to see if there are
messages to log immediately.
* Merge #1110: Make fallthrough explicit for libworker.c.
* For #1110: Test for fallthrough attribute in configure and add
fallthrough attribute annotations.

* Fix #1106: ratelimit-below-domain logs the wrong FROM address.
* Cleanup ede.tdir test.
* For #935 and #1104, clarify RPZ order and semantics.
* Fix to document parameters of auth_zone_verify_zonemd_with_key.
* Fix for #1114: Fix that cache fill for forward-host names is
performed, so that with nonzero target-fetch-policy it fetches
forwarder addresses and uses them from cache. Also updated that
delegation point cache fill routines use CDflag for AAAA
message lookups, so that its negative lookup stops a recursion
since the cache uses the bit for disambiguation for dns64 but
the recursion uses CDflag for the AAAA target lookups, so the
check correctly stops a useless recursion by its cache lookup.
* Fix dnstap test program, cleans up to have clean memory on
exit, for tap_data_free, does not delete NULL items. Also it
does not try to free the tail, specifically in the free of the
list since that picked up the next item in the list for its
loop causing invalid free. Added internal unit test to
unbound-dnstap-socket for that.
* Fix that the worker mem report with alloc stats does not
attempt to print memory use of forwards and hints if they have
been deleted already.
* Fix that alloc stats has strdup checks, it stops debuggers from
complaining about mismatch at free time.
* Fix testbound for alloc stats strdup in util/alloc.c.
* Fix that alloc stats for forwards and hints are printed, and
when alloc stats is enabled, the unit test for unbound control
waits for reloads to complete.
* Fix that for windows the module startup is called and sets up
the module-config.
* Fix spelling for the cache-min-negative-ttl entry in the
example.conf.

Wed May 8 09:15:01 UTC 2024 - Jorik Cronenberg <jorik.cronenberg@suse.com>
- Update to 1.20.0:
Features:
* The config for discard-timeout, wait-limit, wait-limit-cookie,
wait-limit-netblock and wait-limit-cookie-netblock was added,

first checks cachedb before serving the expired response.
* Fix GH#876: [FR] can unbound-checkconf be silenced when
configuration is valid?
Bug Fixes:
* Fix for the DNSBomb vulnerability CVE-2024-33655. Thanks to

redirection answers, and fix validator signature routine for
dealing with the synthesized CNAME for a DNAME without

action cname for the clientip trigger.
* Fix to unify codepath for local alias for rpz cname action
override.
* Fix rpz for cname override action after nsdname and nsip
triggers.

does.
* Merge GH#1030: Persist the openssl and expat directories for
repeated Windows builds.
* Fix that rpz CNAME content is limited to the max number of
cnames.
* Fix rpz, it follows iterator CNAMEs for nsip and nsdname and
sets the reply query_info values, that is better for debug
logging.
* Fix rpz that copies the cname override completely to the temp
region, so there are no references to the rpz region.
* Add rpz unit test for nsip action override.
* Fix rpz for qtype CNAME after nameserver trigger.
* Fix rpz so that rpz CNAME can apply after rpz CNAME. And fix
that clientip and nsip can give a CNAME.
* Fix localdata and rpz localdata to match CNAME only if no
direct type match is available.
* Merge GH#831 from Pierre4012: Improve Windows NSIS installer
script (setup.nsi).
* For GH#831: Format text, use exclamation icon and explicit label
names.

* Fix GH#1034: DoT forward-zone via unbound-control.
* Fix for crypto related failures to have a better error string.
* Fix GH#1035: Potential Bug while parsing port from the
"stub-host" string; also affected forward-zones and
remote-control host directives.
* Fix GH#369: dnstap showing extra responses; for client responses
right from the cache when replying with expired data or
prefetching.
* Fix GH#1040: fix heap-buffer-overflow issue in function
cfg_mark_ports of file util/config_file.c.
* For GH#1040: adjust error text and disallow negative ports in
other parts of cfg_mark_ports.
* Fix comment syntax for view function views_find_view.
* Fix GH#595: unbound-anchor cannot deal with full disk; it will
now first write out to a temp file before replacing the
original one, like Unbound already does for
auto-trust-anchor-file.
* Fixup compile without cachedb.
* Add test for cachedb serve expired.
* Extended test for cachedb serve expired.
* Fix makefile dependencies for fake_event.c.
* Fix cachedb for serve-expired with serve-expired-reply-ttl.
* Fix to not reply serve expired unless enabled for cachedb.
* Fix cachedb for serve-expired with
serve-expired-client-timeout.
* Fixup unit test for cachedb server expired client timeout with
a check if response if from upstream or from cachedb.
* Fixup cachedb to not refetch when serve-expired-client-timeout
is used.
* Merge GH#1049 from Petr Menšík: Py_NoSiteFlag is not needed since
Python 3.8
* Fix GH#1048: Update ax_pkg_swig.m4 and ax_pthread.m4.
* Fix configure, autoconf for GH#1048.
* Add checklock feature verbose_locking to trace locks and
unlocks.
* Fix edns subnet to sort rrset references when storing messages
in the cache. This fixes a race condition in the rrset locks.
* Merge GH#1053: Remove child delegations from cache when
grandchild delegations are returned from parent.
* Fix ci workflow for macos for moved install locations.
* Fix configure flto check error, by finding grep for it.
* Merge GH#1041: Stub and Forward unshare. This has one structure
for them and fixes GH#1038: fatal error: Could not initialize
thread / error: reading root hints.
* Fix to disable fragmentation on systems with IP_DONTFRAG, with
a nonzero value for the socket option argument.
* Fix doc unit test for out of directory build.
* Fix cachedb with serve-expired-client-timeout disabled. The
edns subnet module deletes global cache and cachedb cache when
it stores a result, and serve-expired is enabled, so that the
global reply, that is older than the ecs reply, does not return
after the ecs reply expires.
* Add unit tests for cachedb and subnet cache expired data.
* Man page entry for unbound-checkconf -q.
* Cleanup unnecessary strdup calls for EDE strings.
* Fix doxygen comment for errinf_to_str_bogus.

on positive replies.
[bsc#1221164]
-------------------------------------------------------------------
Wed Feb 28 13:35:31 UTC 2024 - Pedro Monreal <pmonreal@suse.com>
- Update to 1.19.1:

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

inappropriate size. They are removed from responses.
- Fix to move msgparse_rrset_remove_rr code to util/msgparse.c.
- Fix to add EDE text when RRs have been removed due to length.
- Fix to set ede match in unit test for rr length removal.
- Fix to print EDE text in readable form in output logs.
- Fix send of udp retries when ENOBUFS is returned. It stops looping
and also waits for the condition to go away. Reported by Florian Obser.
- Fix authority zone answers for obscured DNAMEs and delegations.
- Merge #936: Check for c99 with autoconf versions prior to 2.70.
- Fix to remove two c99 notations.

- Fix edns subnet so that queries with a source prefix of zero cause the
recursor send no edns subnet option to the upstream.
- Fix that printout of EDNS options shows the EDNS cookie option by name.
- Fix infinite loop when reading multiple lines of input on a broken remote
control socket. Addesses #947 and #948.
- Fix #949: "could not create control compt".
- Fix that cachedb does not warn when serve-expired is disabled about use
of serve-expired-reply-ttl and serve-expired-client-timeout.
- Fix for #949: Fix pythonmod/ubmodule-tst.py for Python 3.x.
- Better fix for infinite loop when reading multiple lines of input on a
broken remote control socket, by treating a zero byte line the same as
transmission end. Addesses #947 and #948.
- For multi Python module setups, clean previously parsed module functions
in __main__'s dictionary, if any, so that only current module functions
are registered.
- Fix #954: Inconsistent RPZ handling for A record returned along with CNAME.
- Fixes for the DNS64 patches.
- Update the dns64_lookup.rpl test for the DNS64 fallback patch.
- Merge #955 from buevsan: fix ipset wrong behavior.
- Update testdata/ipset.tdir test for ipset fix.
- Fix to print detailed errors when an SSL IO routine fails via SSL_get_error.
- Clearer configure text for missing protobuf-c development libraries.
- autoconf.
- Merge #930 from Stuart Henderson: add void to log_ident_revert_to_default
declaration.

- Mention flex and bison in README.md when building from repository source.
-------------------------------------------------------------------
Thu Sep 7 08:03:33 UTC 2023 - Pedro Monreal <pmonreal@suse.com>
- Update to 1.18.0:
* Features:
- Аdd a metric about the maximum number of collisions in lrushah.
- Set max-udp-size default to 1232. This is the same default value
as the default value for edns-buffer-size. It restricts client
edns buffer size choices, and makes unbound behave similar to
other DNS resolvers.
- Add harden-unknown-additional option. It removes unknown records
from the authority section and additional section.
- Added new static zone type block_a to suppress all A queries for
specific zones.
- [FR] Ability to use Redis unix sockets.
- [FR] Ability to set the Redis password.
- Features/dropqueuedpackets, with sock-queue-timeout option that
drops packets that have been in the socket queue for too long.
Added statistics num.queries_timed_out and query.queue_time_us.max
that track the socket queue timeouts.
- 'eqvinox' Lamparter: NAT64 support.
- [FR] Use kernel timestamps for dnstap.
- Add cachedb hit stat. Introduces 'num.query.cachedb' as a new
statistical counter.
- Add SVCB dohpath support.
- Add validation EDEs to queries where the CD bit is set.
- Add prefetch support for subnet cache entries.
- Add EDE (RFC8914) caching.
- Add support for EDE caching in cachedb and subnetcache.
- Downstream DNS Server Cookies a la RFC7873 and RFC9018. Create server
cookies for clients that send client cookies. This needs to be explicitly
turned on in the config file with: `answer-cookie: yes`.
* Bug Fixes
- Response change to NODATA for some ANY queries since 1.12.
- Fix not following cleared RD flags potentially enables
amplification DDoS attacks.
- Set default for harden-unknown-additional to no. So that it
does not hamper future protocol developments.
- Fix to ignore entirely empty responses, and try at another authority.
This turns completely empty responses, a type of noerror/nodata into

- update to 1.9.6
This release contains a number of security related fixes found in
a security audit
Features:
- The unbound.conf includes are sorted ascending, for include
statements with a '*' from glob.
- drop-tld.diff in contrib/ : adds option drop-tld: yesno that drops 2 label
queries, to stop random floods. Apply with
patch -p1 < contrib/drop-tld.diff and compile.
From Saksham Manchanda (Secure64). Please note that we think this
will drop DNSKEY and DS lookups for tlds and hence break DNSSEC
lookups for downstream clients.
- Add new configure option `--enable-fully-static` to enable full static
build if requested; in relation to #91.
- Add make distclean that removes everything configure produced,
and make maintainer-clean that removes bison and flex output.
- unbound-fuzzers.tar.bz2 in contrib/ : three programs for fuzzing, that
are 1:1 replacements for unbound-fuzzme.c that gets created after applying
the contrib/unbound-fuzzme.patch. They are contributed by

- update to 1.9.3
Features:
- PR #28: IPSet module, by Kevin Chou. Created a module to support
the ipset that could add the domain's ip to a list easily.
Needs libmnl, and --enable-ipset and config it, doc/README.ipset.md.
- Merge PR #6: Python module: support multiple instances
- Merge PR #5: Python module: define constant MODULE_RESTART_NEXT
- Merge PR #4: Python module: assign something useful to the
per-query data store 'qdata'

- Fix for #24: Fix abort due to scan of auth zone masters using old
address from previous scan.
- Fix to omit RRSIGs from addition to the ipset.
- Fix to make unbound-control with ipset, remove unused variable,
use unsigned type because of comparison, and assign null instead
of compare with it. Remade lex and yacc output.
- make depend
- Added documentation to the ipset files (for doxygen output).
- Fix python dict reference and double free in config.
- Fix memleak in unit test, reported from the clang 8.0 static analyzer.
- For #45, check that 127.0.0.1 and ::1 are not used in unbound.conf

unbound-checkconf prints a warning if it is found in forward-addr or
stub-addr statements.
- Fix for possible assertion failure when answering respip CNAME from
cache.
- Fix in respip addrtree selection. Absence of addr_tree_init_parents()
call made it impossible to go up the tree when the matching netmask is
too specific.

if minimal-responses is enabled, also the additional for negative
responses is removed.
- Fix #49: Set no renegotiation on the SSL context to stop client
session renegotiation.

- Fix unittest valgrind false positive uninitialised value report,
where if gcc 9.1.1 uses -O2 (but not -O1) then valgrind 3.15.0
issues an uninitialised value for the token buffer at the str2wire.c
rrinternal_get_owner() strcmp with the '@' value. Rewritten to use
straight character comparisons removes the false positive. Also
valgrinds --expensive-definedness-checks=yes can stop this false
positive.

-------------------------------------------------------------------
Mon Oct 8 13:42:15 UTC 2018 - Michael Ströder <michael@stroeder.com>
- update to 1.8.1:
Number of bug fixes, a list of features added and some defaults changed.
Features:
- Perform TLS SNI indication of the host that is being contacted
for DNS over TLS service. It sets the configured tls auth name.
This is useful for hosts that apart from the DNS over TLS services
also provide other (web) services.
Bug Fixes:
- More explicitly mention the type of ratelimit when applying
ip-ratelimit.
- Fix spelling error in header, from getdns commit by Andreas Gelmini.
- iana port update.
- Fixed unused return value warnings in contrib/fastrpz.patch for
asprintf.
- Fix to squelch respip warning in unit test, it is printed at
higher verbosity settings.
- Fix spelling errors.
- Fix initialisation in remote.c
- Fix seed for random backup code to use explicit zero when wiped.
- exit log routine is annotated as noreturn function.
- free memory leaks in config strlist and str2list insert functions.
- do not move unused argv variable after getopt.
- Remove unused if clause in testcode.
- in testcode, free async ids, initialise array, and check for null
pointer during test of the test. And use exit for return to note
irregular program stop.
- Free memory leak in config strlist append.
- make sure nsec3 comparison salt is initialized.
- unit test has clang analysis.
- remove unused variable assignment from iterator scrub routine.
- check for null in delegation point during iterator refetch
in forward zone.
- neater pointer cast in libunbound context quit routine.
- initialize statistics totals for printout.
- in authzone check that node exists before adding rrset.
- in unbound-anchor, use readwrite memory BIO.
- assertion in autotrust that packed rrset is formed correctly.
- Fix memory leak when message parse fails partway through copy.
- remove unused udpsize assignment in message encode.
- nicer bio free code in unbound-anchor.
- annotate exit functions with noreturn in unbound-control.
- Fix compile on Mac for unbound, provide explicit_bzero when libc
does not have it.
- Fix unbound for openssl in FIPS mode, it uses the digests with
the EVP call contexts.
- Fix that with harden-below-nxdomain and qname minisation enabled
some iterator states for nonresponsive domains can get into a
state where they waited for an empty list.
- Stop UDP to TCP failover after timeouts that causes the ping count
to be reset by the TCP time measurement (that exists for TLS),
because that causes the UDP part to not be measured as timeout.
- Fix #4156: Fix systemd service manager state change notification.
- Fix #4149: Add SSL cleanup for tcp timeout.
- Fix #4188: IPv6 forwarders without ipv6 result in SERVFAIL, fixes
qname minimisation with a forwarder when connectivity has issues
from rejecting responses.
- fastrpz.patch fixed.
-------------------------------------------------------------------
Thu Sep 17 17:00:00 UTC 2018 - michael@stroeder.com
- update to 1.8.0:
Number of bug fixes, a list of features added and some defaults changed.
Features
- unbound-control auth_zone_reload _zone_ option rereads the zonefile.
- unbound-control auth_zone_transfer _zone_ option starts the probe
sequence for a master to transfer the zone from and transfers when
a new zone version is available.
- num.queries.tls counter for queries over TLS.
- log port number with err_addr logs.
- dns64-ignore-aaaa: config option to list domain names for which the
existing AAAA is ignored and dns64 processing is used on the A
record.
- Fix #4112: Fix that unbound-anchor -f /etc/resolv.conf will not pass
if DNSSEC is not enabled. New option -R allows fallback from
resolv.conf to direct queries.
- Note RFC8162 support. SMIMEA record type can be read in by the
zone record parser.
- Patches from Jim Hague (Sinodun) for EDNS KeepAlive.
- Add config tcp-idle-timeout (default 30s). This applies to
client connections only; the timeout on TCP connections upstream
is unaffected.
- Add edns-tcp-keepalive and edns-tcp-keepalive timeout options
and implement option in client responses.
- Add delay parameter to streamtcp, -d secs.
To be used when testing idle timeout.
- Expose if a query (or a subquery) was ratelimited (not src IP
ratelimiting) to libunbound under 'ub_result.was_ratelimited'.
This also introduces a change to 'ub_event_callback_type' in
libunbound/unbound-event.h.
- Patch to implement tcp-connection-limit from Jim Hague (Sinodun).
This limits the number of simultaneous TCP client connections
from a nominated netblock.
- Fix #4142: unbound.service.in: improvements and fixes.
Add unit dependency ordering (based on systemd-resolved).
Add 'CAP_SYS_RESOURCE' to 'CapabilityBoundingSet' (fixes warnings
about missing privileges during startup). Add 'AF_INET6' to
'RestrictAddressFamilies' (without it IPV6 can't work). From
Guido Shanahan.
- unbound-checkconf checks if modules exist and prints if they are
not compiled in the name of the wrong module.
- Patch for stub-no-cache and forward-no-cache options that disable
caching for the contents of that stub or forward, for when you
want immediate changes visible, from Bjoern A. Zeeb.
- Upgraded crosscompile script to include libunbound DLL in the
zipfile.
- Set libunbound to increase current, because the libunbound change
to the event callback function signature. That needs programs,
that use it, to recompile against the new header definition.
- log-servfail: yes prints log lines that say why queries are
returning SERVFAIL to clients.
- log-local-actions: yes option for unbound.conf that logs all the
local zone actions, a patch from Saksham Manchanda (Secure64).
- #4146: num.query.subnet and num.query.subnet_cache counters.
- #4140: Expose repinfo (comm_reply) to the inplace_callbacks. This
gives access to reply information for the client's communication
point when the callback is called before the mesh state (modules).
Changes to C and Python's inplace_callback signatures were also
necessary.
- Set defaults to yes for a number of options to increase speed and
resilience of the server. The so-reuseport, harden-below-nxdomain,
and minimal-responses options are enabled by default. They used
to be disabled by default, waiting to make sure they worked. They
are enabled by default now, and can be disabled explicitly by
setting them to "no" in the unbound.conf config file. The reuseport
and minimal options increases speed of the server, and should be
otherwise harmless. The harden-below-nxdomain option works well
together with the recently default enabled qname minimisation, this
causes more fetches to use information from the cache.
- Added serve-expired-ttl and serve-expired-ttl-reset options.
Bug Fixes
- Windows example service.conf edited with more windows specific
configuration.
- #4108: systemd reload hang fix.
- Fix usage printout for unbound-host, hostname has to be last
argument on BSDs and Windows.

- Update libunbound/python/examples/dnssec_test.py example code to
also set the 20326 trust anchor for the root in the example code.

config statements.
- Fix permission denied printed for auth zone probe random port nrs.
- Fix documentation ambiguity for tls-win-cert in tls-upstream and
forward-tls-upstream docs.
- iana port update.
- Fix round robin for failed addresses with prefer-ip6: yes
- Note in documentation that the cert name match code needs
OpenSSL 1.1.0 or later to be enabled.

- Print error if SSL name verification configured but not available
in the ssl library.
- Fix that ratelimit and ip-ratelimit are applied after reload of
changed config file.
- Resize ratelimit and ip-ratelimit caches if changed on reload.
- Fix #4129 unbound-control error message with wrong cert permissions
is too cryptic.
- Fix #4130: print text describing -dd and unbound-checkconf on
config file read error at startup, the errors may have been moved
away by the startup process.
- Fix #4131: for solaris, error YY_CURRENT_BUFFER undeclared.
- Fix use-systemd readiness signalling, only when use-systemd is yes
and not in signal handler.
- Fix #4135: 64-bit Windows Installer Creates Entries Under The
Wrong Registry Key, reported by Brian White.

- Implement progressive backoff of TCP idle/keepalive timeout.
- Fix 'make depend' to work when build dir is not project root.

- Fix to remove systemd sockaddr function check, that is not
always present. Make socket activation more lenient. But not
different when socket activation is not used.
- Fix #4136: insufficiency from mismatch of FLEX capability between
released tarball and build host. Fix to unconditionally call
destroy in daemon.c.
- Make capsforid fallback QNAME minimisation aware.
- document --enable-subnet in doc/README.
- Fix #4144: dns64 module caches wrong (negative) information.
- Fix that printout of error for cycle targets is a verbosity 4
printout and does not wrongly print it is a memory error.
- Fix segfault in auth-zone read and reorder of RRSIGs.
- Fix contrib/fastrpz.patch.

enabled.
- Fix lintflags for lint on FreeBSD.

in a view with view-first, makes queries check for answers from the
local-zones defined outside of views.
-------------------------------------------------------------------
Thu Jun 21 09:19:02 UTC 2018 - michael@stroeder.com
- update to 1.7.3
Features
- #4102 for NSD, but for Unbound. Named unix pipes do not use
certificate and key files, access can be restricted with file and
directory permissions. The option control-use-cert is no longer
used, and ignored if found in unbound.conf.
- Rename tls-additional-ports to tls-additional-port, because every
line adds one port.
Bug Fixes
- Don't count CNAME response types received during qname minimisation
as query restart.
- #4100: Fix stub reprime when it becomes useless.
- Fix crash if ratelimit taken into use with unbound-control
instead of with unbound.conf.
- Patch to fix openwrt for mac os build darwin detection in configure.
- #4103: Fix that auth-zone does not insist on SOA record first in
file for url downloads.

for windows users to use the CA certificates from the Windows cert
stores, tls-win-cert: yes in unbound.conf.
* The code has been updated with a speed up that improves performance for
large numbers of incoming TCP and TLS connections.
* There is an option to allow to ignore an unset RD bit for access control
subnets and always allow recursion to the request.
-------------------------------------------------------------------
Thu May 3 16:38:07 UTC 2018 - michael@stroeder.com
- update to 1.7.1
Features
- Add --with-libhiredis, unbound support for a new cachedb
backend that uses a Redis server as the storage. This
implementation depends on the hiredis client library
(https://redislabs.com/lp/hiredis/).
And unbound should be built with both --enable-cachedb and
--with-libhiredis[=PATH] (where $PATH/include/hiredis/hiredis.h
should exist). Patch from Jinmei Tatuya (Infoblox).
- Create additional tls service interfaces by opening them on other
portnumbers and listing the portnumbers as additional-tls-port: nr.
- ED448 support.
- num.query.authzone.up and num.query.authzone.down statistics counters.
- Accept both option names with and without colon for get_option
and set_option.
- low-rtt and low-rtt-pct in unbound.conf enable the server selection
of fast servers for some percentage of the time.
- num.query.aggressive.NOERROR and num.query.aggressive.NXDOMAIN
statistics counters.
- allow-notify: config statement for auth-zones.
- Can set tls authentication with forward-addr: IP#tls.auth.name
And put the public cert bundle in tls-cert-bundle: "ca-bundle.pem".
such as forward-addr: 9.9.9.9@853#dns.quad9.net or
1.1.1.1@853#cloudflare-dns.com
- list_auth_zones unbound-control command.

- Check "result" in dup_all(), by Florian Obser.
- Fix #4043: make test fails due to v6 presentation issue in macOS.
- Fix unable to resolve after new WLAN connection, due to auth-zone
failing with a forwarder set. Now, auth-zone is only used for
answers (not referrals) when a forwarder is set.
- Combine write of tcp length and tcp query for dns over tls.
- nitpick fixes in example.conf.
- Fix above stub queries for type NS and useless delegation point.
- Fix unbound-control over pipe with openssl 1.1.1, the TLSv1.3
tls_choose_sigalg routine does not allow the ciphers for the pipe,
so use TLSv1.2.
- Fix that flush_zone sets prefetch ttl expired, so that with
serve-expired enabled it'll start prefetching those entries.
- Fix downstream auth zone, only fallback when auth zone fails to
answer and fallback is enabled.
- Fix for max include depth for authzones.
- Fix memory free on fail for $INCLUDE in authzone.
- Fix that an internal error to look up the wrong rr type for
auth zone gets stopped, before trying to send there.
- Fix auth zone target lookup iterator.
- Fix auth-zone retry timer to be on schedule with retry timeout,
with backoff. Also time a refresh at the zone expiry.

verify the server's certificate (RFC 8310 support).
- For addr with #authname and no @port notation, the default is 853.
- man page documentation for dns-over-tls forward-addr '#' notation.
- removed free from failed parse case.
- Fix #4091: Fix that reload of auth-zone does not merge the zonefile
with the previous contents.

- Fix contrib/fastrpz.patch for this release.
- Fix auth https for libev.
- Fix memory leak when caching wildcard records for aggressive NSEC use
- Fix for crash in daemon_cleanup with dnstap during reload,
from Saksham Manchanda.
- Also that for dnscrypt.
-------------------------------------------------------------------
Sun Apr 22 19:26:03 UTC 2018 - michael@stroeder.com
- Commented configuration directive dlv-anchor-file: in unbound.conf
(see bsc#1055060). The DLV key file is deliberately still
shipped in the package so users could easily re-enable this.
-------------------------------------------------------------------
Wed Apr 4 11:54:01 UTC 2018 - michael@stroeder.com
- update to 1.7.0
Features
- auth-zone provides a way to configure RFC7706 from unbound.conf,
eg. with auth-zone: name: "." for-downstream: no for-upstream: yes
fallback-enabled: yes and masters or a zonefile with data.
- Aggressive use of NSEC implementation. Use cached NSEC records to
generate NXDOMAIN, NODATA and positive wildcard answers.
- Accept tls-upstream in unbound.conf, the ssl-upstream keyword is
also recognized and means the same. Also for tls-port,
tls-service-key, tls-service-pem, stub-tls-upstream and
forward-tls-upstream.
- [dnscrypt] introduce dnscrypt-provider-cert-rotated option,
from Manu Bretelle.
This option allows handling multiple cert/key pairs while only
distributing some of them.
In order to reliably match a client magic with a given key without
strong assumption as to how those were generated, we need both key and
cert. Likewise, in order to know which ES version should be used.
On the other hand, when rotating a cert, it can be desirable to only
serve the new cert but still be able to handle clients that are still
using the old certs's public key.
The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not
publish the cert as part of the DNS's provider_name's TXT answer.
- Update B root ipv4 address.
- make ip-transparent option work on OpenBSD.
- Fix #2801: Install libunbound.pc.
- ltrace.conf file for libunbound in contrib.

- Fix #2141 - for libsodium detect lack of entropy in chroot, print
a message and exit.
- Fix #2492: Documentation libunbound.
- Fix #2882: Unbound behaviour changes (wrong) when domain-insecure is
set for stub zone. It no longer searches for DNSSEC information.
- Fix #3299 - forward CNAME daisy chain is not working
- Fix link failure on OmniOS.
- Check whether --with-libunbound-only is set when using --with-nettle
or --with-nss.
- Fix qname-minimisation documentation (A QTYPE, not NS)
- Fix that DS queries with referral replies are answered straight
away, without a repeat query picking the DS from cache.
The correct reply should have been an answer, the reply is fixed
by the scrubber to have the answer in the answer section.
- Fix that expiration date checks don't fail with clang -O2.
- Fix queries being leaked above stub when refetching glue.
- Copy query and correctly set flags on REFUSED answers when cache

Thu Dec 15 16:28:44 UTC 2016 - michael@stroeder.com
- update to 1.6.0
Features
* Added generic EDNS code for registering known EDNS option codes,
bypassing the cache response stage and uniquifying mesh states. Four
EDNS option lists were added to module_qstate
(module_qstate.edns_opts_*) to store EDNS options from/to front/back side.
* Added two flags to module_qstate (no_cache_lookup, no_cache_store)
that control the modules' cache interactions.
* Added code for registering inplace callback functions. The registered
functions can be called just before replying with local data or Chaos,
replying from cache, replying with SERVFAIL, replying with a resolved
query, sending a query to a nameserver. The functions can inspect the
available data and maybe change response/query related data (i.e. append
EDNS options).
* Updated Python module for the above.
* Updated Python documentation.
* Added views functionality.
* Added qname-minimisation-strict config option.
* Patch that resolves CNAMEs entered in local-data conf statements that
point to data on the internet, from Jinmei Tatuya (Infoblox).
* serve-expired config option: serve expired responses with TTL 0.
* .gitattributes line for githubs code language display.
* log-identity: config option to set sys log identity, patch from "Robin
H. Johnson" (robbat2@gentoo.org).
* Added stub-ssl-upstream and forward-ssl-upstream options.
* Added local-zones and local-data bulk addition and removal
functionality in unbound-control (local_zones, local_zones_remove,
local_datas and local_datas_remove).
* g.root-servers.net has AAAA address.
Bug Fixes

Pavel Odintsov.
* Fix failure to build on arm64 with no sbrk.
* Set OpenSSL security level to 0 when using aNULL ciphers.
* configure detects ssl security level API function in the autoconf
manner. Every function on its own, so that other libraries (eg.
LibreSSL) can develop their API without hindrance.
* Fix #1154: segfault when reading config with duplicate zones.
* Note that for harden-below-nxdomain the nxdomain must be secure, this
means nsec3 with optout is insufficient.
* Fix #1155: test status code of unbound-control in 04-checkconf, not
the status code from the tee command.
* Fix #1158: reference RFC 8020 "NXDOMAIN: There Really Is Nothing
Underneath" for the harden-below-nxdomain option.

-------------------------------------------------------------------
Wed Feb 17 15:55:34 UTC 2016 - mrueckert@suse.de
- revert the previous change which would not solve the problem as
the library package requires the unbound-anchor package
instead introduce a libunbound-devel-mini package which holds the
shared library and devel files with a minimal build requires.
-------------------------------------------------------------------
Thu Feb 4 13:01:35 UTC 2016 - meissner@suse.com
- split off a libunbound package with less buildrequires to
allow shorter buildcycles when built by gnutls. bsc#964346
-------------------------------------------------------------------
Thu Dec 10 11:48:46 UTC 2015 - michael@stroeder.com

-------------------------------------------------------------------
Thu Oct 15 19:31:43 UTC 2015 - michael@stroeder.com
- update to 1.5.6
Features
- Default for ssl-port is port 853, the temporary port assignment for
secure domain name system traffic. If you used to rely on the older
default of port 443, you have to put a clause in unbound.conf for
that. The new value is likely going to be the standardised port number
for this traffic.
- ANY responses include DNAME records if present, as per Evan Hunt's
remark in dnsop.
Bug Fixes
- Fix segfault in the dns64 module in the formaterror error path.
- Fix manpage to suggest using SIGTERM to terminate the server.

- Change default of harden-algo-downgrade to off. This is lenient
for algorithm rollover.
- Added permit-small-holddown config to debug fast 5011 rollover.
- Allow certificate chain files to allow for intermediate
certificates. (thanks Daniel Kahn Gillmor)
- Enable ECDHE for servers. Where available, use
SSL_CTX_set_ecdh_auto() for TLS-wrapped server configurations
to enable ECDHE. Otherwise, manually offer curve p256. Client
connections should automatically use ECDHE when available.
(thanks Daniel Kahn Gillmor)
- Feature --enable-pie option to that builds PIE binary.
[bugzilla: 699 ]
- Feature --enable-relro-now option that enables full read-only
relocation. [bugzilla: 700 ]
- New IPs for for h.root-servers.net. [bugzilla: 702 ]
Bug Fixes
- Fix setting forwarders with unbound-control forward implicitly
turns on forward-first. [bugzilla: 681 ]

num-threads. [bugzilla: 690 ]
- please afl-gcc (llvm) for uninitialised variable warning.
- Fix mktime in unbound-anchor not using UTC.
- Fix 5011 anchor update timer after reload.
- 5011 implementation does not insist on all algorithms, when
harden-algo-downgrade is turned off.
- Document in the manual more text about configuring locally
served zones.
- Document that local-zone nodefault matches exactly and
transparent can be used to release a subzone.
- Fix that configure script does not detect LibreSSL 2.2.2
[bugzilla: 694 ]
- Fix deadlock for local data add and zone add when
unbound-control list_local_data printout is interrupted.

official configure options.
-------------------------------------------------------------------
Fri Sep 4 13:37:38 UTC 2015 - mrueckert@suse.de
- enable event api
- enable dnstap support
-------------------------------------------------------------------
Thu Jul 9 10:16:32 UTC 2015 - michael@stroeder.com
- update to 1.5.4
Features
- [bugzilla: 644 ] harden-algo-downgrade option, if turned off,
fixes the reported excessive validation failure when multiple
algorithms are present. If set to 'no', it allows the weakest
algorithm to validate the zone.
- stats reports tcp usage, of incoming-num-tcp buffers.
- contrib/unbound_smf22.tar.gz: Solaris SMF installation/removal
scripts. Contributed by Yuri Voinov.
- Add ip-transparent config option for bind to non-local addresses.
- Synthesize ANY responses from cache. Does not search exhaustively,
but MX,A,AAAA,SOA,NS also CNAME.
- unbound-control list_insecure command shows the negative trust
anchors currently configured, patch from Jelte Jansen.
- ratelimit feature, ratelimit: 1000, can be used to turn it on. It
ratelimits recursion effort per zone. For particular names you can
configure exceptions in unbound.conf.
- Ratelimit does not apply to prefetched queries, and
ratelimit-factor is default 10. Repeated normal queries get resolved
and with prefetch stay in the cache.
- unbound-control ratelimit_list lists high rate domains.
- caps-whitelist in unbound.conf allows whitelist of loadbalancers
that cannot work with caps-for-id or its fallback.
- RFC 7553 RR type URI support, is now enabled by default.
- cache-max-negative-ttl config option, default 3600.
- Add local-zone type inform_deny, that logs query and drops answer.
Bug Fixes
- Unbound exits with a fatal error when the auto-trust-anchor-file
fails to be writable. This is seconds after startup. You can load a
readonly auto-trust-anchor-file with trust-anchor-file. The file has
to be writable to notice the trust anchor change, without it, a trust
anchor change will be unnoticed and the system will then become
inoperable.
- DLV is going to be decommissioned. Advice to stop using it, and
put text in the example configuration and man page to that effect.
- Patch from Brad Smith that syncs compat/getentropy_linux with
OpenBSD's version (2015-03-04).
- 0x20 fallback improved: servfail responses do not count as missing
comparisons (except if all responses are errors), inability to find
nameservers does not fail equality comparisons, many nameservers does
not try to compare more than max-sent-count, parse failures start 0x20
fallback procedure.
- store caps_response with best response in case downgrade response
happens to be the last one.
- Document that incoming-num-tcp increase is good for large servers.
- Fix lintian warning in unbound-checkconf man page (from Andreas
Schulze).
- Updated default keylength in unbound-control-setup to 3k.
- Fixup compile on cygwin, more portable openssl thread id.
- Use reallocarray for integer overflow protection, patch submitted
by Loganaden Velvindron.
- Fixed to add integer overflow checks on allocation (defense in depth).
- Fix segfault on user not found at startup (from Maciej Soltysiak).
- [bugzilla: 657 ] Fix that libunbound(3) recommends deprecated
CRYPTO_set_id_callback.
- If unknown trust anchor algorithm, and libressl is used, error
message encourages upgrade of the libressl package.
- rename ldns subdirectory to sldns to avoid name collision.
- [bugzilla: 660 ] Fix interface-automatic broken in the presence of
asymmetric routing.
- Libunbound skips dos-line-endings from etc/hosts.
- Fix crash in dnstap: Do not try to log TCP responses after timeout.
- Fix that get_option for cache-sizes does not print double newline.
- [bugzilla: 663 ] Fix that ssl handshake fails when using unix
socket because dh size is too small.
- [bugzilla: 664 ] libunbound python3 related fixes (from Tomas
Hozza); Use print_function also for Python2. libunbound examples:
produce sorted output. libunbound-Python: libldns is not used anymore.
Fix issue with Python 3 mapping of FILE* using file_py3.i from ldns.
- Fix leaked dns64prefix configuration string.
- Removed contrib/unbound_unixsock.diff, because it has been
integrated, use control-interface: /path in unbound.conf.
- Change syntax of particular validator error to be easier for
machine parse, swap rrset and ip adres info so it looks like:
validation failure <www.example.nl. TXT IN>: signature crypto failed
from 2001:DB8:7:bba4::53 for <*.example.nl. NSEC IN>
- Fix that unparseable error responses are ratelimited.
- SOA negative TTL is capped at minimumttl in its rdata section.
- [bugzilla: 674 ] Do not free pointers given by getenv.
- [bugzilla: 677 ] Fix CNAME corresponding to a DNAME was checked
incorrectly and was therefore always synthesized (thanks to Valentin
Dietrich). And fix DNAME responses from cache that failed internal
chain test.
- iana portlist update.

- Contrib windows scripts from Yuri Voinov added to src/contrib:
create_unbound_ad_servers.cmd: enters anti-ad server lists.
unbound_cache.cmd: saves and loads the cache. Also warmup.cmd
(and .sh): warm up the DNS cache with your MRU domains.
- Added unbound-control-setup.cmd from Yuri Voinov to the windows
unbound distribution set. It requires openssl installed in
%PATH%.
- Implement draft-ietf-dnsop-rfc6598-rfc6303-01.
- Feature, unblock-lan-zones: yesno that you can use to make
unbound perform 10.0.0.0/8 and other reverse lookups normally,
for use if unbound is running service for localhost on localhost.
- unbound-host -D enabled dnssec and reads root trust anchor from
the default root key file that was compiled in.
- Add AAAA for B root server to default root hints.
- unbound-control status reports if so-reuseport was successful.
- so-reuseport is available on BSDs(such as FreeBSD 10) and OS/X.
- arc4random in compat/ and getentropy, explicit_bzero, chacha
for dependencies, from OpenBSD. arc4_lock and sha512 in compat.
This makes arc4random available on all platforms, except when
compiled with LIBNSS (it uses libNSS crypto random).
- Patch from Dag-Erling Smorgrav that implements that: unbound
-dd does not fork in the background and also logs to stderr.
- DNS64 from Viagenie (BSD Licensed), written by Simon Perrault.
Initial commit of the patch from the FreeBSD base (with its
fixes). This adds a module (for module-config in unbound.conf)
dns64 that performs DNS64 processing, see README.DNS64.
- Patch add msg, rrset, infra and key cache sizes to stats
command from Maciej Soltysiak.
- DNSTAP support, with a patch from Farsight Security, written by
Robert Edmonds. The --enable-dnstap needs libfstrm and
protobuf-c. It is BSD licensed (see dnstap/dnstap.c). Also
--with-libfstrm and --with-protobuf-c configure options.
- type CDS and CDNSKEY types.
- Updated the TCP_BACLOG from 5 to 256, so that the tcp accept
queue is longer and more tcp connections can be handled.
- Add ub_ctx_add_ta_autr function to add a RFC5011 automatically
tracked trust anchor to libunbound.
Bug Fixes
- Fix print filename of encompassing config file on read failure.
- Patch from Stuart Henderson to build unbound-host man from
.1.in.
- [bugzilla: 569] Fix do_tcp is do-tcp in unbound.conf man page.
- [bugzilla: 572] Fix unit test failure for systems with
different /etc/ services.
- iana portlist updated.
- [bugzilla: 574] Fix make test fails on Ubuntu 14.04. Disabled
remote-control in testbound scripts.
- Documented that dump_requestlist only prints queries from
thread 0.
- [bugzilla: 567] Fix unbound lists if forward zone is secure or
insecure with +i annotation in output of list_forwards, also
for list_stubs (for NetworkManager integration). And remove ':'
from output of stub and forward lists, this is easier to parse.
- [bugzilla: 554] Fix use unsigned long to print 64bit statistics
counters on 64bit systems.
- [bugzilla: 558] Fix failed prefetch lookup does not remove
cached response but delays next prefetch (in lieu of caching a
SERVFAIL).
- [bugzilla: 545] Fix improved logging, the ip address of the
error is printed on the same log-line as the error.
- [bugzilla: 502] Fix explain that do-ip6 disable does not stop
AAAA lookups, but it stops the use of the ipv6 transport layer
for DNS traffic.
- Fix compile with libevent2 on FreeBSD.
- Change MAX_SENT_COUNT from 16 to 32 to resolve some cases easier.
- Fixup out-of-directory compile with unbound-control-setup.sh.in.
- Code cleanup patch from Dag-Erling Smorgrav, with compiler
issue fixes from FreeBSD's copy of Unbound, he notes: Generate
unbound-control-setup.sh at build time so it respects prefix
and sysconfdir from the configure script. Also fix the umask
to match the comment, and the comment to match the umask. Add
const and static where needed. Use unions instead of playing
pointer poker. Move declarations that are needed in multiple
source files into a shared header. Move sldns_bgetc() from
parse.c to buffer.c where it belongs. Introduce a new header
file, worker.h, which declares the callbacks that all workers
must define. Remove those declarations from libworker.h.
Include the correct headers in the correct places. Fix a few
dummy callbacks that don't match their prototype. Fix some
casts. Hide the sbrk madness behind #ifdef HAVE_SBRK. Remove a
useless printf which breaks reproducible builds. Get rid of
CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're no longer
used. Add unbound-control-setup.sh to the list of generated
files. The prototype for libworker_event_done_cb() needs to be
moved from libunbound/libworker.h to libunbound/worker.h.
- Fix caps-for-id fallback, and added fallback attempt when
servers drop 0x20 perturbed queries.
- [bugzilla: 593] Fix segfault or crash upon rotating logfile.
- fake-rfc2553 patch (thanks Benjamin Baier).
- LibreSSL provides compat items, check for that in configure.
- [bugzilla: 596] Bail out of unbound-control list_local_zones
when ssl write fails.
- Fix endian.h include for OpenBSD.
- [bugzilla: 603] Fix unbound-checkconf -o option should skip
verification checks.
- Fixup doc/unbound.doxygen to remove obsolete 1.8.7 settings.
- Update unbound manpage with more explanation (from Florian Obser).
- Fix tcp timer waiting list removal code.

- [bugzilla: 612] Fix create service with service.conf in present
directory and auto load it.
- [bugzilla: 613] Allow tab ws in var length last rdfs (in ldns
str2wire).
- [bugzilla: 614] Fix man page variable substitution bug.
- Whitespaces after $ORIGIN are not part of the origin dname
(ldns).
- $TTL's value starts at position 5 (ldns).
- Fix unbound-checkconf check for module config with dns64
module.
- Fix unbound capsforid fallback, it ignores TTLs in comparison.
- [bugzilla: 617] Fix in ldns in unbound, lowercase WKS services.
- Fix ctype invocation casts.
- Disabled use of SSLv3 in remote-control and ssl-upstream.
- Redefine internal minievent symbols to unique symbols that
helps linking on platforms where the linker leaks names across
modules.
- Fix bug where forward or stub addresses with same address but
different port number were not tried.
