dea722c4ac Add some checks when changing configuration. 2012-07-21 15:02:17 +02:00

cc0c35267f Call event_init() after detaching. 
Otherwise, the call to daemon() could close filedescriptors in use by libevent
itself; for example if it uses kqueue or epoll instead of a select() or poll()
backend.

1d4590ca5c Prefer routes with lower weight as long as they do not increase the number of hops. 
This should improve traffic to nodes that are not directly reachable somewhat.

4c8ead9874 Allow more configuration variables to be changed when reloading configuration. 
In particular, Subnets may be added or removed from the local node on the fly.

4591e96c76 Never remove items from cmdline_conf. 
We should treat cmdline_conf as const, so we can call read_config_options()
more than once with prefix = NULL.

68a20876d0 Use minor protocol version to determine whether to use ECDH key exchange between nodes. 2012-07-20 01:02:51 +02:00
Guus Sliepen
76a3ada4eb Put minor protocol version in connection options so other nodes can see it. 
This allows two nodes that do not have a meta-connection with each other see
which version they are.

68de7b481e When exporting configuration files, don't copy Name variables. 
These interfere with tincctl import. Besides, host configuration files should
not contain Name at all.

bce177767d Fix crash when handling the ALRM signal. 
In retry() the function do_outgoing_connection() is called, which can delete
items from the connection_tree, so when walking the tree we must first save the
pointer to the next item.

291a59b5b7 free_connection_partially(): also reset remote protocol version infos 
The used remote protocol can change between two reconnects, aka if
the remote side has enabled/disabled for example their ExperimentalProtocols
setting.

5ae19cb0bb Add support for proxying through an external command. 
Proxy type "exec" can be used to have an external script or binary set
up an outgoing connection. Standard input and output will be used to
exchange data with the external command. The variables REMOTEADDRESS and
REMOTEPORT are set to the intended destination address and port.

fb5588856f Add support for SOCKS 5 proxies. 
This only covers outgoing TCP connections, and supports only
username/password authentication or no authentication.

b58d95eb29 Add basic support for SOCKS 4 and HTTP CONNECT proxies. 
When the Proxy option is used, outgoing connections will be made via the
specified proxy. There is no support for authentication methods or for having
the proxy forward incoming connections, and there is no attempt to proxy UDP.

84531fb6e6 Allow broadcast packets to be sent directly instead of via the MST. 
When the "Broadcast = direct" option is used, broadcast packets are not sent
and forwarded via the Minimum Spanning Tree to all nodes, but are sent directly
to all nodes that can be reached in one hop.

One use for this is to allow running ad-hoc routing protocols, such as OLSR, on
top of tinc.

8792b9a9f3 Remove confusing error message for failed reading in ECDSA keys. 
Most likeley the error is that there just is no valid key inside the used
host file, and in this case errno just contains a random value from the
last previously failed call.

a5bb6d40fb sptps_stop(): clear pointers after free to avoid double free. 
sptps_stop() may get called twice on some failed connection setups.

535a55100b Allow environment variables to be used for Name. 
When the Name starts with a $, the rest will be interpreted as the name of an
environment variable containing the real Name. When Name is $HOST, but this
environment variable does not exist, gethostname() will be used to set the
Name. In both cases, illegal characters will be converted to underscores.
