Tobias Brunner 9d0f8a3a95 Use a separate (volatile) variable for certificate alias 
If a connection is started while certificates are still loading and the
initiation is then canceled a deadlock could result if the daemon is
trying to enumerate the certificates just then.

Tobias Brunner ae4f1ea180 Native counterpart of VpnService.Builder added, exposed by charonservice 2012-08-13 11:09:33 +02:00
Tobias Brunner 5215d512bf Adapter class added around VpnService.Builder which allows to access it via JNI 2012-08-13 11:00:29 +02:00
Tobias Brunner f12b3ad2c9 Don't print hosts as %any if %+H is used 
That is, the plus sign can be used in the format string to force a numeric
string representation of all host_t objects even 0.0.0.0 and :: which
would otherwise be printed as %any and %any6.
 2012-08-13 11:00:29 +02:00

Tobias Brunner d4f7675199 Implement kernel_ipsec_t.bypass_socket() via JNI and VpnService.protect() 2012-08-13 11:00:27 +02:00
Tobias Brunner 03de55ad98 CharonVpnService binds to VpnStateService and does basic state updates 2012-08-13 11:00:27 +02:00
Tobias Brunner a4f9028e08 CharonVpnService reacts on Intents and properly inits/deinits charon 
Charon is initialized with every new connection attempt and
deinitialized when the service is terminated or it receives an empty
Intent (or before starting a new connection).

A separate thread is used to handle the connection attempts, this thread
acts as main thread for charon.
 2012-08-13 11:00:27 +02:00
Tobias Brunner d1220566ef Service added that keeps track of VPN state and notifies listeners about changes 
It is ensured that listeners are notified only from the main thread.
 2012-08-13 11:00:27 +02:00
Tobias Brunner 175088517f Add an Android specific kernel_ipsec_t implementation 
This is pretty much a proxy class that delegates everything (that is
currently supported) to libipsec.
 2012-08-13 11:00:27 +02:00
Tobias Brunner 24447cf49f Add an Android specific kernel_net_t implementation 
This currently provides only no-ops and is just added because a
kernel-net implementation is required and kernel-netlink can't be used
at the moment.
 2012-08-13 11:00:27 +02:00
Tobias Brunner 6e04147743 Clone the current VPN profile before updating the password 
Storing the password on the original object would be problematic in case
the user mistypes the password (no prompt would be shown the second time).

An alternative would be to just return the ID of the selected profile
and then fetch it from the database.
 2012-08-13 11:00:26 +02:00
Tobias Brunner 8d4eea5325 Allow VpnProfile objects to be cloned 2012-08-13 11:00:26 +02:00
Tobias Brunner b1340aa129 Prompt the user for a password if none is configured in the VPN profile 2012-08-13 11:00:26 +02:00
Tobias Brunner fcb5448017 Allow selection of a CA certificate for a VPN profile 
This solution is just temporary as it really is not that user-friendly
to select CA certificates with a Spinner widget.
 2012-08-13 11:00:26 +02:00
Tobias Brunner 8db37772f5 Simplified asynchronous loading of CA certificates in MainActivity 2012-08-13 11:00:26 +02:00
Tobias Brunner b21979f12f Added simple adapter for trusted certificates (to be used with a Spinner widget) 2012-08-13 11:00:26 +02:00

Tobias Brunner 6316b50280 Renamed main Activity (shorter name in Launcher) 2012-08-13 11:00:25 +02:00
Tobias Brunner 0b362ed837 MainActivity starts CharonVpnService if a VpnProfile is clicked in the list 
This is done by implementing the OnVpnProfileSelectedListener interface
provided by VpnProfileListFragment.
 2012-08-13 11:00:25 +02:00
Tobias Brunner c8b942a1e2 Menu option added to reload cached CA certificates 
This might be required if the user installs a new CA certificate.
 2012-08-13 11:00:25 +02:00

Tobias Brunner 19567a5e3a Helper function added to handle Java exceptions in native code 2012-08-13 11:00:25 +02:00
Tobias Brunner 95e9a12c28 Don't attach to actual Java threads (or already attached ones) 
We check this by trying to retrieve a JNIEnv object from the JVM,
if one is returned the current thread is not native (created from Java)
or the thread is already attached.
 2012-08-13 11:00:25 +02:00
