 Security statement
 ------------------
 
-In August 2000, we discovered the existence of a security hole in all versions
+This version uses an experimental and unfinished cryptographic protocol. Use
-of tinc up to and including 1.0pre2. This had to do with the way we exchanged
+it at your own risk.
-keys. Since then, we have been working on a new authentication scheme to make
-tinc as secure as possible. The current version uses the OpenSSL library and
-uses strong authentication with RSA keys.
-
-On the 29th of December 2001, Jerome Etienne posted a security analysis of tinc
-1.0pre4. Due to a lack of sequence numbers and a message authentication code
-for each packet, an attacker could possibly disrupt certain network services or
-launch a denial of service attack by replaying intercepted packets. The current
-version adds sequence numbers and message authentication codes to prevent such
-attacks.
-
-On September the 15th of 2003, Peter Gutmann contacted us and showed us a
-writeup describing various security issues in several VPN daemons. He showed
-that tinc lacks perfect forward security, the connection authentication could
-be done more properly, that the sequence number we use as an IV is not the best
-practice and that the default length of the HMAC for packets is too short in
-his opinion. We do not know of a way to exploit these weaknesses, but these
-issues are being addressed in the tinc 1.1 branch.
-
-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.

 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
+/etc/tinc/nets.boot to find out which networks have to be started.

 This will start a tinc daemon that reads its configuration from

 nobody, and creates a network interface called "vpn". Ifup then sets the
 address and netmask on that interface.

-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,

-# SYNOPSIS
-#
-#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
-#
-# DESCRIPTION
-#
-#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
-#   added in between.
-#
-#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
-#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
-#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
-#   FLAG.
-#
-#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

-#

-#   HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
-#   Intel compilers.  For a given compiler, the Fortran flags are much more

-#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
