+The Sweet32 attack affects versions of tinc prior to 1.0.30.
+
+On September 6th, 2018, Michael Yonly contacted us and provided
+proof-of-concept code that allowed a remote attacker to create an
+authenticated, one-way connection with a node, and also that there was a
+possibility for a man-in-the-middle to force UDP packets from a node to be sent
+in plaintext. The first issue was trivial to exploit on tinc versions prior to
+1.0.30, but the changes in 1.0.30 to mitigate the Sweet32 attack made this
+weakness much harder to exploit. These issues have been fixed in tinc 1.0.35.
+The new protocol in the tinc 1.1 branch is not susceptible to these issues.

+    systemctl disable tinc@<netname>
+  
+  If you do not have systemd installed, the SysV init script will continue to

 tinc for Debian
-----------------------
+---------------
 
 The manual for tinc is also available as info pages, type `info tinc'
 to read it.
 
-The system startup script for tinc, /etc/init.d/tinc, uses the file
+There are several ways in which tinc may be automatically started at boot:
-/etc/tinc/nets.boot to find out which networks have to be started.
 
- -- Ivo Timmermans <ivo@debian.org>, Wed, 31 May 2000, 19:56:05 +0200
+Systemd
+-------
+
+Since 1.0.27-1, the tinc package comes with native systemd service files.
+To enable and start a net, call:
+
+systemctl enable tinc@<netname>
+systemctl start tinc@<netname>
+
+This will cause a tincd to be started which uses the configuration from
+/etc/tinc/<netname>, and also makes sure that it will be started next time your
+system boots.
+
+Apart from controlling individual instances, you can also start/stop/reload all
+enabled instances simultaneously by omitting @<netname>, for example:
+
+systemctl reload tinc
+
+Note that when you have systemd installed on your system, the file
+/etc/tinc/nets.boot will not be used anymore to automatically start tinc
+daemons. If the variable EXTRA is defined in /etc/default/tinc, it will be
+passed on to tinc. The variable LIMITS is however not used.
+
+The service files that come with this package start tinc unconditionally.
+However, tinc does support socket activation. If you wish to write a socket
+unit for tinc, use the ListenStream option to specify on which port(s) and
+address(es) tinc should listen.
+
+SysVinit
+--------
+
+The system startup script for tinc, /etc/init.d/tinc, uses the file
+/etc/tinc/nets.boot to find out which networks have to be started. Use one
+netname per line. Lines starting with a # are ignored.
+
+/etc/network/interfaces
+-----------------------
+
+You can create a stanza in /etc/network/interfaces, and add a line with
+"tinc-net <netname>". This will cause a tincd to be started which uses the
+configuration from /etc/tinc/<netname>. You can use an inet static (with
+address and netmask options) or inet dhcp stanza, in which case the ifup will
+configure the VPN interface and you do not need to have a tinc-up script.
+
+The following options are also recognized and map directly to the corresponding
+command line options for tincd:
+
+tinc-config <directory>
+tinc-debug <level>
+tinc-mlock yes
+tinc-logfile <filename>
+tinc-pidfile <filename>
+tinc-chroot yes
+tinc-user <username>
+
+An example stanza:
+
+iface vpn inet static
+	address 192.168.2.42
+	netmask 255.255.0.0
+	tinc-net myvpn
+	tinc-debug 1
+	tinc-mlock yes
+	tinc-user nobody
+	tinc-pidfile /tmp/tinc.pid
+
+This will start a tinc daemon that reads its configuration from
+/etc/tinc/myvpn, logs at debug level 1, locks itself in RAM, runs as user
+nobody, and creates a network interface called "vpn". Ifup then sets the
+address and netmask on that interface.

+Package: tinc
+Version: 1.0.33-1
+Severity: important
+
+Dear Guus,
+
+I have been using tinc since 2009 and it is great!
+
+When PMTUDiscovery=yes and Mode=switch, and if ipv6 is used inside
+tinc, the ICMPv6 "Packet Too Big" packets have incorrect checksums.
+It can be reproduced by `ping6 <host in tinc> -s 1800` and `tcpdump -i
+<tinc interface>`.  Consequently, the host ignores the tinc-generated
+ICMPv6 packets, PMTUDiscovery does not work and the connections freeze
+when data flows are big.
+
+I find the bug is gone if the function "inet_checksum" in route.c is
+not inlined, either by compiling tinc with "-O2
+-fno-inline-functions", or apply a patch such as,
+
+diff --git a/src/route.c b/src/route.c

+
+
+
+I have tested with gcc-7.3.0 and gcc-5.4.0.  They behaved the same.  I
+am not good at assembly to find out what really happened, but it is
+for sure that inet_checksum does not work as expected if compiled
+inline.

-/* alloca.c -- allocate automatically reclaimed memory
-   (Mostly) portable public-domain implementation -- D A Gwyn
-
-   This implementation of the PWB library alloca function,
-   which is used to allocate space off the run-time stack so
-   that it is automatically reclaimed upon procedure exit,
-   was inspired by discussions with J. Q. Johnson of Cornell.
-   J.Otto Tennant <jot@cray.com> contributed the Cray support.
-
-   There are some preprocessor constants that can
-   be defined when compiling for your specific system, for
-   improved efficiency; however, the defaults should be okay.
-
-   The general concept of this implementation is to keep
-   track of all alloca-allocated blocks, and reclaim any
-   that are found to be deeper in the stack than the current
-   invocation.  This heuristic does not reclaim storage as
-   soon as it becomes invalid, but it will do so eventually.
-
-   As a special case, alloca(0) reclaims storage without
-   allocating any.  It is a good idea to use alloca(0) in
-   your main control loop, etc. to force garbage collection.  */

+#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space

+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
