2018-04-28Use validation instead of two-way bindingJason A. Donenfeld
This is insane, but it appears to be working. We essentially store things in a separate class for editing, and then commit it back at a given time. This business with onViewStateRestored in both TunnelEditorFragment and in TunnelDetailFragment is buggy and likely wrong. In general TunnelEditorFragment should probably be rewritten. The relationship with the changed name is not clear. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-04-27Do not do DNS lookups for IPsJason A. Donenfeld
This involves reflection, which is a bummer, but it's better than doing unnecessary DNS lookups. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-04-27Throw IllegalArgumentExceptions when arguments are badJason A. Donenfeld
This will make the two way data binding crash more, but it will improve the robustness of the config file parser, which deals with exceptions gracefully, and when we move to one way data binding, it will help with that too. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-04-26Manifest: disable always-on VPNJason A. Donenfeld
We don't actually comprehend how this works yet, so disable it. But we'll need to add support for this at some point. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-04-25GoBackend: bring down tunnels when revoked or disconnectedJason A. Donenfeld
This synchronizes the OS's connection state with ours, such as when the user disconnects using the system UI. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-04-17GoBackend: default MTU is 1280Jason A. Donenfeld
This sucks, but it works with mobile networks. Later we can do something sophisticated like we do with wg-quick.c, but not now. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-04-17Remove sloppy java with enterprise java horrorsJason A. Donenfeld
Since the amount of mind numbing boiler plate has been increased, this must be the proper way to do things. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-04-17GoBackend: Handle vpn service expirationAurélien Chabot
After a timeout the android system is destroying the vpn service when it is not used. By using a completable future we can wait for the service to be relaunch on demand. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-02-03manifest: Add permission to read external storageSamuel Holland
This fixes support for file managers that don't proxy the file access from the file selection dialog through a content provider, and just return a raw file:// URL. In this case, resolver.openInputStream() tries to open the file directly, and fails with "Permission denied". Signed-off-by: Samuel Holland <samuel@sholland.org>

It can't work and may be crashing the runtime. Use a lock object to avoid exposing the synchronization in the class's interface. Signed-off-by: Samuel Holland <samuel@sholland.org>
