 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.
+
 Cryptography is a hard thing to get right. We cannot make any
 guarantees. Time, review and feedback are the only things that can
 prove the security of any cryptographic product. If you wish to review
 tinc or give us feedback, you are strongly encouraged to do so.

+  This package now provides native systemd service files, allowing multiple

+  /etc/tinc/nets.boot will be converted to service instances once during this
+  upgrade. Afterwards, you can enable and disable networks using:
+  
+    systemctl enable tinc@<netname>
+    systemctl disable tinc@<netname>
+  
+  If you do not have systemd installed, the SysV init script will continue to
+  work as usual. For more information, see README.Debian.

+tinc for Debian
+---------------
+
+The manual for tinc is also available as info pages, type `info tinc'
+to read it.
+
+There are several ways in which tinc may be automatically started at boot:
+
+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.

+ tinc is a daemon with which you can create a virtual private network
+ (VPN). One daemon can handle multiple connections, so you can
+ create an entire (moderately sized) VPN with only one daemon per

+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
+index ff82c06e..cd55383a 100644
+--- a/src/route.c
++++ b/src/route.c
+@@ -60,7 +60,7 @@ static const size_t opt_size = sizeof(struct nd_opt_hdr);
+

+-static uint16_t inet_checksum(void *data, int len, uint16_t prevsum) {

+ 	uint16_t *p = data;
+ 	uint32_t checksum = prevsum ^ 0xFFFF;
+
+
+
+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.
+
+Thanks!

+Yours,
+Benda

+7.3.1 Linux
+-----------
+
+There are many Linux distributions, and historically, many of them had
+their own way of starting programs at boot time.  Today, a number of
+major Linux distributions have chosen to use systemd as their init
+system.  Tinc ships with systemd service files that allow you to start
+and stop tinc using systemd.  There are two service files:
+'tinc.service' is used to globally enable or disable all tinc daemons
+managed by systemd, and 'tinc@NETNAME.service' is used to enable or
+disable specific tinc daemons.  So if one has created a tinc network
+with netname 'foo', then you have to run the following two commands to
+ensure it is started at boot time:
+
+     systemctl enable tinc
+     systemctl enable tinc@foo
+
+   To start the tinc daemon immediately if it wasn't already running,
+use the following command:
+
+     systemctl start tinc@foo
+
+   You can also use 'systemctl start tinc', this will start all tinc
+daemons that are enabled.  You can stop and disable tinc networks in the
+same way.
+
+   If your system is not using systemd, then you have to look up your
+distribution's way of starting tinc at boot time.

+
+7.3.2 Windows
+-------------
+
+On Windows, if tinc is started without the '-D' or '--no-detach' option,
+it will automatically register itself as a service that is started at
+boot time.  When tinc is stopped using the '-k' or '--kill', it will
+also automatically unregister itself.  Once tinc is registered as a
+service, it is also possible to stop and start tinc using the Windows
+Services Manager.
