Version 1.1pre11 December 27 2014
|
||||
|
||||
* Added a "network" command to list or switch networks.
|
||||
|
||||
* Switched to Ed25519 keys and the ChaCha-Poly1305 cipher for the new protocol.
|
||||
|
||||
* AutoConnect is now a boolean option, when enabled tinc always tries to keep
|
||||
at least three meta-connections open.
|
||||
|
||||
* The new protocol now uses UDP much more often.
|
||||
|
||||
* Tinc "del" and "get" commands now return a non-zero exit code when they
|
||||
don't find the requested variable.
|
||||
|
||||
* Updated documentation.
|
||||
|
||||
* Added a "DeviceStandby" option to defer running tinc-up until a working
|
||||
connection is made, and which on Windows will also change the network
|
||||
interface link status accordingly.
|
||||
|
||||
* Tinc now tells the resolver to reload /etc/resolv.conf when it receives
|
||||
SIGALRM.
|
||||
|
||||
* Improved error messages and event loop handling on Windows.
|
||||
|
||||
* LocalDiscovery now uses local address learned from other nodes, and is
|
||||
enabled by default.
|
||||
|
||||
* Added a "BroadcastSubnet" option to change the behavior of broadcast packets
|
||||
in router mode.
|
||||
|
||||
* Added support for dotted quad notation in IPv6 (e.g. ::1.2.3.4).
|
||||
|
||||
* Improved format of printed Subnets, MAC and IPv6 addresses.
|
||||
|
||||
* Added a "--batch" option to force the tinc CLI to run in non-interactive
|
||||
mode.
|
||||
|
||||
* Improve default Device selection on *BSD and Mac OS X.
|
||||
|
||||
* Allow running tinc without RSA keys.

Version 1.1pre10 February 7 2014
|
||||

* Fixed a crash when using Name = $HOST while $HOST is not set.

|
||||
* Use AES-256-GCM for the new protocol.
|
||||
|
||||
* Updated support for Solaris.
|
||||
|
||||
* Allow running tincd without a private ECDSA key present when
|
||||
ExperimentalProtocol is not explicitly set.
|
||||
|
||||
* Enable various compiler hardening flags by default.
|
||||
|
||||
* Added support for a "conf.d" configuration directory.
|
||||
|
||||
* Fix tinc-gui on Windows, also allowing it to connect to a 32-bits tincd when
|
||||
tinc-gui is run in a 64-bits Python environment.
|
||||
|
||||
* Added a "ListenAddress" option, which like BindToAddress adds more listening
|
||||
address/ports, but doesn't bind to them for outgoing sockets.
|
||||
|
||||
* Make invitations work better when the "invite" and "join" commands are not
|
||||
run interactively.
|
||||
|
||||
* When creating meta-connections to a node for which no Address statement is
|
||||
specified, try to use addresses learned from other nodes.
|
||||
|
||||
Thanks to Dennis Joachimsthaler and Florent Clairambault for their contribution
|
||||
to this version of tinc.
|
||||
|
||||
Version 1.1pre9 September 8 2013
|
||||
|
||||
* The UNIX socket is now created before tinc-up is called.

When using 256 bits Ed25519 keys, the AES-256-CTR cipher and
|
||||
HMAC-SHA-256 digest algorithm, the sizes are as follows:
|
||||
|
||||
ECDH_SIZE: 67 (= ceil(521/8) + 1)
|
||||
ECDSA_SIZE: 141 (= 2 * ceil(521/8) + 9)
|
||||
ECDH_SIZE: 32 (= 256/8)
|
||||
ECDSA_SIZE: 64 (= 2 * 256/8)
|
||||
CIPHER_KEYSIZE: 48 (= 256/8 + 128/8)
|
||||
DIGEST_KEYSIZE: 32 (= 256/8)

# Check whether the given FLAG works with the current language's compiler

# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on

# If EXTRA-FLAGS is defined, it is added to the current language's default

# flags (e.g. CFLAGS) when the check is done. The check is thus made with

||||
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to

# force the compiler to issue an error when a bad flag is given.

# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this

For some reason, Microsoft decided to make the FD_WRITE event edge-triggered instead of level-triggered,

which is the opposite of what select() does. In practice, that means that if a FD_WRITE event triggers,
|
||||
it will never trigger again until a send() returns EWOULDBLOCK. Since the semantics of this event loop
|
||||
is that write events are level-triggered (i.e. they continue firing until the socket is full), we need
|
||||
to emulate these semantics by making sure we fire each IO_WRITE that is still writeable.
|
||||
|
||||
Note that technically FD_CLOSE has the same problem, but it's okay because user code does not rely on
|
||||
this event being fired again if ignored.
