 commit 28a1501b9a8b4c730f7f965d6b2e8fc50feba261
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Sat Mar 10 13:31:36 2012 +0100
    Releasing 1.0.17.
 commit 4712d8f92e63e86e835ffb624d6399343ee568ea
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Sat Mar 10 13:23:08 2012 +0100
    Update copyright notices.
 commit 5b0f5ad958d6db4e73aebc5ee6c608cdae81b7b5
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Thu Mar 8 23:23:39 2012 +0100
    Make sure disabling old RSA keys works on Windows.
    Seeking in files and rewriting parts of them does not seem to work properly on
    Windows. Instead, when old RSA keys are found when generating new ones, the
    file containing the old keys is copied to a temporary file where the changes
    are made, and that file is renamed back to the original filename. On Windows,
    we cannot atomically replace files with a rename(), so we need to move the
    original file out of the way first. If anything fails, the new code will warn
    that the user has to solve the problem by hand.
 commit 2f1c337c541fcb7e2c62aeeab245ff7a43eb51a5

    Accept Subnets passed with the -o option when StrictSubnets = yes.
 commit 63f8303a5dc1758876451a580a8317dbc3d295d6
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Fri Mar 2 16:09:58 2012 +0100
    Only log errors sending UDP packets when debug level >= 5.
    Since tinc will fall back to TCP or route via another node, it is not necessary
    to log such errors unconditionally.
 commit ae5249610954af17c68c547bb1b45ad286ad647e
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Sun Feb 26 16:23:02 2012 +0100
    Only use broadcast at the start of the PMTU discovery phase.
    For local peer discovery, only a handful of packets are necessary for
    peers to detect each other.
 commit 5140656de6bcfda72951a7827b05414ce306e3ca
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Sat Feb 25 22:11:30 2012 +0100
    Stricter checks against routing loops.
    If a packet that had to be sent via an intermediate hop, and that intermediate
    hop was the one that sent the packet, we drop it.
 commit f1d5eae643cdf537ef357f10f2da8ff83bdf32b4
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Sat Feb 25 21:46:18 2012 +0100
    Don't send ICMP Time Exceeded messages for other Time Exceeded messages.
    That would be silly.
 commit 5a28aa7b8b0ab6237c2eab5f8b11253ea3ec5a05
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Wed Feb 22 23:17:43 2012 +0100
    Add LocalDiscovery option which tries to detect peers on the local network.
    Currently, this is implemented by sending IPv4 broadcast packets to the
    LAN during path MTU discovery.

 commit ac48c4ee8c09c8144f830cb66386b9dbe7298440
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Tue Feb 21 14:06:55 2012 +0100
    Fix check for raw socket support.
    Also, move some variables so there are no compiler warnings about unused
    variables when there is no support for raw sockets.
 commit d9ad3d313d96d30ef45cd53367dff9a855a396d4
 Author: Guus Sliepen <guus@tinc-vpn.org>

 commit 8420a0c8bde1781db04dd2436eb9d5dca5a1732a
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Mon Feb 20 17:19:00 2012 +0100
    Allow disabling of broadcast packets.
    The Broadcast option can be used to cause tinc to drop all broadcast and
    multicast packets. This option might be expanded in the future to selectively
    allow only some broadcast packet types.
 commit ea415ccc1690d6e5864a7500977b181e5c8faafe

 commit cff5a844a3e6b494f4a4f6eb5b48a84780f2d0e5
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Mon Feb 20 16:52:53 2012 +0100
    Don't bind outgoing TCP sockets anymore.
    The code introduced in commit 41a05f59ba2c3eb5caab555f096ed1b9fbe69ee3 is not
    needed anymore, since tinc has been able to handle UDP packets from a different
    source address than those of the TCP packets since 1.0.10.  When using multiple
    BindToAddress statements, this code does not make sense anymore, we do want the
    kernel to choose the source address on its own.
 commit 0233b1d710222cb09be0cbd08c1297e3ece38a9f
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Mon Feb 20 16:34:02 2012 +0100
    Decrement TTL of incoming packets.
    Tinc will now, by default, decrement the TTL field of incoming IPv4 and IPv6
    packets, before forwarding them to the virtual network device or to another
    node. Packets with a TTL value of zero will be dropped, and an ICMP Time
    Exceeded message will be sent back.
    This behaviour can be disabled using the DecrementTTL option.
 commit 6289859ab365dc1c0d420323174418b316b14502
 Author: Guus Sliepen <guus@tinc-vpn.org>

 commit 708314df2f61675d0f54e541c9fff62ac1f433b5
 Author: Guus Sliepen <guus@tinc-vpn.org>
 Date:   Fri Feb 17 16:13:38 2012 +0100
    Set FD_CLOEXEC flag on all sockets.
    Scripts called by tinc would inherit its open filedescriptors. This could
    be a problem if other long-running daemons are started from those scripts,
    if those daemons would not close all filedescriptors before going into the
    background.
    Problem found and solution suggested by Nick Hibma.

    Allow linking with multiple device drivers.
    Apart from the platform specific tun/tap driver, link with the dummy and
    raw_socket devices, and optionally with support for UML and VDE devices.
    At runtime, the DeviceType option can be used to select which driver to
    use.

 commit e838289683c0039fac0ae6172d40b4177c17911b

    Prevent read_rsa_public_key() from returning an uninitialized RSA structure.
    In case the config file could not be opened a new but unitialized RSA structure
    would be returned, causing a segmentation fault later on. This would only
    happen in the case that the config file could be opened before, but not when
    read_rsa_public_key() was called. This situation could occur when the --user
    option was used, and the config files were not readable by the specified user.

 * Add LocalDiscovery option allowing tinc to detect peers that are behind the
   same NAT.
 * Accept Subnets passed with the -o option when StrictSubnets = yes.
 * Disabling old RSA keys when generating new ones now also works properly on
   Windows.

@item dummy
 Use a dummy interface.
 No packets are ever read or written to a virtual network device.
 Useful for testing, or when setting up a node that only forwards packets for other nodes.
@cindex raw_socket
@item raw_socket
 Open a raw socket, and bind it to a pre-existing
@var{Interface} (eth0 by default).
 All packets are read from this interface.
 Packets received for the local node are written to the raw socket.
 However, at least on Linux, the operating system does not process IP packets destined for the local host.
@cindex UML
@item uml (not compiled in by default)
 Create a UNIX socket with the filename specified by
@var{Device}, or @file{@value{localstatedir}/run/@var{netname}.umlsocket}

 Tinc will wait for a User Mode Linux instance to connect to this socket.
@cindex VDE

@var{Device}, or @file{@value{localstatedir}/run/vde.ctl}

 Also, in case tinc does not seem to correctly interpret packets received from the virtual network device,
 it can be used to change the way packets are interpreted:

 Tinc will expect packets read from the virtual network device
 to start with a four byte header containing the address family,
 followed by an IP header.
 This mode should support both IPv4 and IPv6 packets.

 Under Windows, this variable is used to select which network interface will be used.
 If you specified a Device, this variable is almost always already correctly set.
@cindex LocalDiscovery
@item LocalDiscovery = <yes | no> (no) [experimental]
 When enabled, tinc will try to detect peers that are on the same local network.
 This will allow direct communication using LAN addresses, even if both peers are behind a NAT
 and they only ConnectTo a third node outside the NAT,
 which normally would prevent the peers from learning each other's LAN address.
 Currently, local discovery is implemented by sending broadcast packets to the LAN during path MTU discovery.
 This feature may not work in all possible situations.

 If specified as @var{HOST}.@var{KEY}=@var{VALUE},
 this will set the host configuration variable @var{KEY} of the host named @var{HOST} to @var{VALUE}.
