We do not backport security fixes to +older (minor) versions. In the event a new major version is released (e.g. from +3.2.18 to 4.0.0), support will also be provided on the latest minor version of +the previous major version (3.2.18) for a period of one year from the release of +the new major version (4.0.0). + +In the event that, during this period, a new patch or minor version of the +previous major version is released, then support on these versions will only be +provided for the remainder of the one-year-period. + +You can find detailed information on our software support policy here: + +https://www.nlnetlabs.nl/support/software-support-policy/ + +## Reporting a Vulnerability + +We take security very seriously. If you have discovered a security vulnerability +in one of our projects and you would like to report it to us, you can send an +encrypted message to our Security Entry Point. + +Details are described here: + +https://www.nlnetlabs.nl/security-report/ diff --git a/contrib/unbound/cachedb/cachedb.c b/contrib/unbound/cachedb/cachedb.c index 725bc6ce8b38..b07743d85259 100644 --- a/contrib/unbound/cachedb/cachedb.c +++ b/contrib/unbound/cachedb/cachedb.c @@ -1,865 +1,865 @@ /* * cachedb/cachedb.c - cache from a database external to the program module * * Copyright (c) 2016, NLnet Labs.

Slower, but allows use of large outgoing port ranges. --with-libexpat=path specify explicit path for libexpat. --with-libhiredis=path specify explicit path for libhiredis. --with-libnghttp2=path specify explicit path for libnghttp2. --with-dnstap-socket-path=pathname set default dnstap socket path --with-protobuf-c=path Path where protobuf-c is installed, for dnstap --with-libsodium=path Path where libsodium is installed, for dnscrypt --with-libmnl=path specify explicit path for libmnl. --with-libunbound-only do not build daemon and tool programs Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L if you have libraries in a nonstandard directory LIBS libraries to pass to the linker, e.g. -l CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if you have headers in a nonstandard directory CPP C preprocessor YACC The `Yet Another Compiler Compiler' implementation to use. Defaults to the first program found out of: `bison -y', `byacc', `yacc'. YFLAGS The list of arguments that will be passed by default to $YACC. This script will default YFLAGS to the empty string to avoid a default value of `-d' given by some make applications. LT_SYS_LIBRARY_PATH User-defined run-time library search path. PKG_CONFIG path to pkg-config utility PKG_CONFIG_PATH directories to add to pkg-config's search path PKG_CONFIG_LIBDIR path overriding pkg-config's built-in search path SYSTEMD_CFLAGS C compiler flags for SYSTEMD, overriding pkg-config SYSTEMD_LIBS linker flags for SYSTEMD, overriding pkg-config SYSTEMD_DAEMON_CFLAGS C compiler flags for SYSTEMD_DAEMON, overriding pkg-config SYSTEMD_DAEMON_LIBS linker flags for SYSTEMD_DAEMON, overriding pkg-config PYTHON_VERSION The installed Python version to use, for example '2.3'. This string will be appended to the Python interpreter canonical name. Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.

This has a number of new features. The dependency on libfstrm is removed. The fstrm protocol code resides in dnstap/dnstap_fstrm.h and dnstap/dnstap_fstrm.c. This contains a brief definition of what unbound needs. The make unbound-dnstap-socket builds a debug tool, unbound-dnstap-socket. It can listen, accept multiple DNSTAP streams and print information. Commandline options control it. Unbound can reconnect if the unix domain socket file socket is closed. This uses exponential backoff after which it uses a one second timer to throttle cpu down. There is also support to use TCP and TLS for connecting to the log server. There are new config options to turn them on, in the dnstap section in the man page and example config file. dnstap-ip with IP address of server for TCP or TLS use. dnstap-tls to turn on TLS. And dnstap-tls-server-name, dnstap-tls-cert-bundle, dnstap-tls-client-key-file and dnstap-tls-client-cert-file to configure the certificates for server authentication and client authentication, or leave at "" to not use that. 27 February 2020: George - Merge PR #171: Add additional compilers and platforms to Travis testing, by noloader. 27 February 2020: Wouter - Fix #169: Fix warning for daemon/remote.c output may be truncated from snprintf. - Fix #170: Fix gcc undefined sanitizer signed integer overflow warning in signature expiry RFC1982 serial number arithmetic. - Fix more undefined sanitizer issues, in respip copy_rrset null dname, and in the client_info_compare routine for null memcmp. 26 February 2020: Wouter - iana portlist updated. 25 February 2020: Wouter - Fix #165: Add prefer-ip4: yesno config option to prefer ipv4 for using ipv4 filters, because the hosts ip6 netblock /64 is not owned by one operator, and thus reputation is shared. 24 February 2020: George - Merge PR #166: Fix typo in unbound.service.in, by glitsj16. 20 February 2020: Wouter - Updated contrib/unbound_smf23.tar.gz with Solaris SMF service for Unbound from Yuri Voinov. - master branch has 1.10.1 version. 18 February 2020: Wouter - protect X509_CHECK_FLAG_NO_PARTIAL_WILDCARDS with ifdef for different openssl versions. 17 February 2020: Wouter - changelog point where the tag for 1.10.0rc2 release is.

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 also introduces a change to 'ub_event_callback_type' in libunbound/unbound-event.h. - Tidy pylib tests. 3 August 2018: Wouter - Revert previous change for #4136: because it introduces build problems. - New fix for #4136: This one ignores lex without without yylex_destroy. 1 August 2018: Wouter - 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. - iana port list update. 31 July 2018: Wouter - Patches from Jim Hague (Sinodun) for EDNS KeepAlive. - Sort out test runs when the build directory isn't the project root directory. - Add config tcp-idle-timeout (default 30s).

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.
