commit 6e6b037ef4fd9877aeb1d947da7364409fa8cbb7

|
||||
|
||||
Check for EVP_EncryptInit_ex instead of SHA1_Version in OpenSSL.
|
||||
|
||||
The latter function disappeared, and wasn't actually used in tinc, so now we
|
||||
check on a function that we do use.

commit 257cb6ac60bb0924720de9e252cdf7f4759bf741

Author: Guus Sliepen <guus@tinc-vpn.org>
|

|
||||
|
||||
Always use the default signal handler for ABRT signals.
|
||||
|
||||
This will allow coredumps to be generated when tinc is daemonized.
|
||||
Also add the -kABRT option.

commit eacb5a28fb4c1515633f2b8a206e7067bc7b8f0c

|
||||
Increase threshold for detecting two nodes with the same Name.
|
||||
|
||||
In commit 4a21aabada23d1d2c8a10f54dd7248171c4ec82f, code was added to detect
|
||||
contradicting ADD_EDGE and DEL_EDGE messages being sent, which is an indication
|
||||
of two nodes with the same Name connected to the same VPN. However, these
|
||||
contradictory messages can also happen when there is a network partitioning. In
|
||||
the former case a loop happens which causes many contradictory message, while
|
||||
in the latter case only a few of those messages will be sent. So, now we
|
||||
increase the threshold to at least 10 of both ADD_EDGE and DEL_EDGE messages.

commit f11c6101f30df645223920bef3eb7592de9bcb79
|

|
||||
|
||||
Fix command-line '-o' option for host configuration
|
||||
|
||||
This fixes a regression introduced by commit 667b1ba while refactoring option
|
||||
parsing code.

||||

commit 0aa86d4b8b3010522e6de8842f5bd29004ba3df6

||||

|
||||
|
||||
Do not set indirect flag on edges from nodes with multiple addresses.
|
||||
|
||||
Since tinc now handles UDP packets with a different source address and port
|
||||
than used for TCP connections, the heuristic to treat edges as indirect when
|
||||
tinc could detect that multiple addresses were used does not make sense
|
||||
anymore, and can actually reduce performance.
|
||||
|
||||
commit 7cf68b5e35c002511cc7468967de6a75934cc998
|
||||
Author: Guus Sliepen <guus@tinc-vpn.org>
|
||||
Date: Fri Feb 18 23:11:43 2011 +0100
|
||||
|
||||
Prevent anything from updating our own UDP address.
|
||||
|
||||
Because we don't want to keep track of that, and this will cause the node
|
||||
structure from being relinked into the node tree, which results in myself
|
||||
pointing to an invalid address.

||||

||||
commit cdbbbfabea173894bd2fb5f28135a04ddc5e3fd7
|
||||
Author: Guus Sliepen <guus@tinc-vpn.org>
|
||||
Date: Fri Feb 18 23:02:11 2011 +0100
|
||||
|
||||
Fix spurious misidentification of incoming UDP packets.
|
||||
|
||||
When a UDP packet was received with an unknown source address/port, and if it
|
||||
failed a HMAC check against known keys, it could still incorrectly assign that
|
||||
UDP address to another node. This would temporarily cause outgoing UDP packets
|
||||
to go to the wrong destination address, until packets from the correct address
|
||||
were received again.

Add support for VDE through libvdeplug.
|
||||
|
||||
When compiled with vde/device.c, tinc will connect to a vde_switch instance
|
||||
instead of using a tun/tap device.

|

Always send MTU probes at least once every PingInterval.
|
||||
|
||||
Before, if MTU probes failed, tinc would stop sending probes until the next
|
||||
time keys were regenerated (by default, once every hour). Now it continues to
|
||||
send them every PingInterval, so it recovers faster from temporary failures.

Use setpriority() instead of nice() on UNIX-like systems.
|

|

The return value of nice() can not reliably indicate errors. The return value
|
||||
of the setpriority() call is well-defined.

Quit when there are too many consecutive errors on the tun/tap device.
|
||||
|
||||
Although transient errors sometimes happen on the tun/tap device (for example,
|
||||
if the kernel is temporarily out of buffer space), there are situations where
|
||||
the tun/tap device becomes permanently broken. Instead of endlessly spamming
|
||||
the syslog, we now sleep an increasing amount of time between consecutive read
|
||||
errors, and if reads still fail after 10 attempts (approximately 3 seconds),
|
||||
tinc will quit.

-n option is specified.

|

|
||||
New '-o' option to configure server or hosts from command line
|
||||
|
||||
Options given on the command line have precedence over configuration from files.
|
||||
|
||||
This can be useful, for example, for a roaming node, for which 'ConnectTo' and
|
||||
<host>.Address depends on its location.

Do not append an address to ANS_KEY messages if we don't know any address.
|
||||
|
||||
This would let tinc raise an exception when an ANS_KEY request crossed a
|
||||
DEL_EDGE request for the node sending the key.

Detect and prevent two nodes with the same Name being on the VPN simultaneously.
|

In this situation, the two nodes will start fighting over the edges they announced.
|

When we have to contradict both ADD_EDGE and DEL_EDGE messages, we log a warning,

and with 25% chance per PingTimeout we quit.

Version 1.0.14 May 8 2011
|
||||
|
||||
* Fixed reading configuration files that do not end with a newline. Again.
|
||||
|
||||
* Allow arbitrary configuration options being specified on the command line.
|
||||
|
||||
* Allow all options in both tinc.conf and the local host config file.
|
||||
|
||||
* Configurable replay window, UDP send and receive buffers for performance tuning.
|
||||
|
||||
* Try harder to get UDP communication back after falling back to TCP.
|
||||
|
||||
* Initial support for attaching tinc to a VDE switch.
|
||||
|
||||
* DragonFly BSD support.
|
||||
|

This is the size of the replay tracking window for each remote
