5e3607b616 Remove GraphDumpFile from the manual and manpages.
This option is not supported in tinc 1.1, "tincctl dump graph" can be used
instead.

In particular, Windows does support many of the timer* macros, except timeradd
and timersub.

d2b19be1a0 Fix use of unitialised values in hash tables.
Not only was Valgrind unhappy about it, it could also result in cache misses.

d9c70767aa Fix check for expired events.
This would trigger a infinite loop if a timeout expired and the next timeout
was not expired yet, but less than 1 second from being expired.

6bc5d626a8 Drop libevent and use our own event handling again.
There are several reasons for this:

- MacOS/X doesn't support polling the tap device using kqueue, requiring a
  workaround to fall back to select().
- On Windows only sockets are properly handled, therefore tinc uses a second
  thread that does a blocking ReadFile() on the TAP-Win32/64 device. However,
  this does not mix well with libevent.
- Libevent, event just the core, is quite large, and although it is easy to get
  and install on many platforms, it can be a burden.
- Libev is more lightweight and seems technically superior, but it doesn't
  abstract away all the platform differences (for example, async events are not
  supported on Windows).

3c1b704733 Improve UDP address selection.
We don't need to search the whole edge tree, we can use the node's own edge
tree since each edge has a pointer to its reverse. Also, we do need to make
sure we try the reflexive address often.

e8bf81794f Send broadcast packets using a random socket, and properly support IPv6.
Before it would always use the first socket, and always send an IPv4 broadcast packet. That
works fine in a lot of situations, but it is better to try all sockets, and to send IPv6 packets
on IPv6 sockets. This is especially important for users that are on IPv6-only networks or that
have multiple physical network interfaces, although in the latter case it probably requires
them to use the ListenAddress variable to create a separate socket for each interface.

0ee139e914 Make sure PMTU discovery works in switch mode with VLAN tags.
Before, when tinc saw a packet larger than the PMTU with a VLAN tag, it would
not know what to do with it, and would just forward it via TCP. Now, tinc
handles 802.1q packets correctly, as long as there is only one tag.

ade4fccad6 Using alloca() for a constant sized buffer is very silly.
Cppcheck said using alloca() in the 21st century is silly anyway.

717ea66d7b Add the AutoConnect option.
When set to a non-zero value, tinc will try to maintain exactly that number of
meta connections to other nodes.  If there are not enough connections, it will
periodically try to set up an outgoing connection to a random node.  If there
are too many connections, it will periodically try to remove an outgoing
connection.

44a24f63ac Fix handling of initial datagram SPTPS packet.
Only the very first packet of an SPTPS session should be send with REQ_KEY,
this signals the peer to abort any previous session and start a new one as
well.

ec1f7e525d sptps.c: Add missing newline to log message. 2012-10-12 17:19:56 +02:00
Guus Sliepen
94ec8d34db Strip newline from incoming SPTPS requests.
Most of the code doesn't care whether requests are terminated with a newline or
not, except that when requests are forwarded, it is assumed they do not have
one and a newline is added.  When a node using SPTPS receives a request from
another SPTPS-using node, and forwards it to a non-SPTPS-using node, this will
result in two consecutive newlines, which the latter node will see as an empty,
and thus invalid, request.
