- Fix #4132: Openness/closeness of RANGE intervals in rpl files.
- Fix #4126: RTT_band too low on VSAT links with 600+ms latency,
adds the option unknown-server-time-limit to unbound.conf that
can be increased to avoid the problem.
- remade makefile dependencies.
- Fix #4152: Logs shows wrong time when using log-time-ascii: yes.
24 October 2018: Ralph
- Add markdel function to ECS slabhash.
- Limit ECS scope returned to client to the scope used for caching.
- Make lint like previous #4154 fix.
22 October 2018: Wouter
- Fix #4192: unbound-control-setup generates keys not readable by
group.
- check that the dnstap socket file can be opened and exists, print
error if not.
- Fix #4154: make ECS_MAX_TREESIZE configurable, with
the max-ecs-tree-size-ipv4 and max-ecs-tree-size-ipv6 options.
22 October 2018: Ralph
- Change fast-server-num default to 3.
8 October 2018: Ralph
- Add fast-server-permil and fast-server-num options.
- Deprecate low-rtt and low-rtt-permil options.
8 October 2018: Wouter
- Squelch log of failed to tcp initiate after TCP Fastopen failure.
5 October 2018: Wouter
- Squelch EADDRNOTAVAIL errors when the interface goes away,
this omits 'can't assign requested address' errors unless
verbosity is set to a high value.
- Set default for so-reuseport to no for FreeBSD. It is enabled
by default for Linux and DragonFlyBSD. The setting can
be configured in unbound.conf to override the default.
- iana port update.
2 October 2018: Wouter
- updated contrib/fastrpz.patch to apply for this version
- dnscrypt.c removed sizeof to get array bounds.
- Fix testlock code to set noreturn on error routine.
- Remove unused variable from contrib fastrpz/rpz.c and
remove unused diagnostic pragmas that themselves generate warnings
- clang analyze test is used only when assertions are enabled.
1 October 2018: Wouter
- tag for release 1.8.1rc1. Became release 1.8.1 on 8 oct, with
fastrpz.patch fix included. Trunk has 1.8.2 in development.
27 September 2018: Wouter
- Fix #4188: IPv6 forwarders without ipv6 result in SERVFAIL, fixes
qname minimisation with a forwarder when connectivity has issues
from rejecting responses.
25 September 2018: Wouter
- 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.
- Fix #4149: Add SSL cleanup for tcp timeout.
17 September 2018: Wouter
- 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.
13 September 2018: Wouter
- 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.
11 September 2018: Wouter
- 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
10 September 2018: Wouter
- 1.8.1 in svn trunk. (changes from 4,5,.. sep apply).
- iana port update.
5 September 2018: Wouter
- Fix spelling error in header, from getdns commit by Andreas Gelmini.
4 September 2018: Ralph
- More explicitly mention the type of ratelimit when applying
ip-ratelimit.
4 September 2018: Wouter
- Tag for 1.8.0rc1 release, became 1.8.0 release on 10 Sep 2018.
31 August 2018: Wouter
- Disable minimal-responses in subnet unit tests.
30 August 2018: Wouter
- Fix that a local-zone with a local-zone-type that is transparent
in a view with view-first, makes queries check for answers from the
local-zones defined outside of views.
28 August 2018: Ralph
- Disable minimal-responses in ipsecmod unit tests.
- Added serve-expired-ttl and serve-expired-ttl-reset options.
27 August 2018: Wouter
- 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.
- next release is called 1.8.0.
- Fix lintflags for lint on FreeBSD.
22 August 2018: George
- #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.
21 August 2018: Wouter
- 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.
- Fix only misc failure from log-servfail when val-log-level is not
enabled.
17 August 2018: Ralph
- Fix classification for QTYPE=CNAME queries when QNAME minimisation is
enabled.
17 August 2018: Wouter
- 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.
- print servfail info to log as error.
- added more servfail printout statements, to the iterator.
- log-servfail: yes prints log lines that say why queries are
returning SERVFAIL to clients.
16 August 2018: Wouter
- Fix warning on compile without threads.
- Fix contrib/fastrpz.patch.
15 August 2018: Wouter
