Davide De Rosa 6fb409b112 Drop UDP packets on no buffer space available

 2019-04-25 14:39:40 +02:00
Davide De Rosa 224a76ac58 Parse --redirect-gateway from configuration 
FIXME: for now only redirects ALL traffic when the option is found
in the configuration file, whatever the arguments.

Also drop unnecessary base options in tests as everything was made
optional recently.

Davide De Rosa 9b8be02c2a Shut down when no IPv4/6 routing available 
Would fake-connect without VPN icon otherwise.
 2019-04-19 09:45:15 +02:00
Davide De Rosa c565e32dcd Add "dev-type tun" to local options 
Plus other hardcoded options like key-method and tls-client.

Seems that older OpenVPN servers didn't send routing info in
PUSH_REPLY if dev-type is not specified explicitly.

Fixes #86
 2019-04-18 13:10:57 +02:00
Davide De Rosa 887e2ae55d Consider stale if HARD_RESET while connected 
Was disconnecting when more than one HARD_RESET_SERVER was
received during negotiation.
 2019-04-17 09:24:16 +02:00
Davide De Rosa 28fd80f4e0 Treat empty DNS servers as nil 
Empty local DNS array was pretty much hiding server-pushed DNS.
 2019-04-17 00:50:53 +02:00
Davide De Rosa 6fd6d228bf Loop pulling plain text from TLS 
There might be more data to read.

Davide De Rosa a2250686b6 Merge OptionsBundle into Configuration 
FIXME: issues with non-optional .cipher and .compressionFraming

Because:

- No pushed cipher (nil) is NOT .aes128cbc
- No pushed framing (nil) is NOT .disabled

Breaks conditions on pushed cipher/framing via PUSH_REPLY.
 2019-04-04 18:51:06 +02:00
Davide De Rosa 7aec0637b2 Move endpoints inside SessionProxy.Configuration 
Make optional.

TunnelKitProvider still gets hostname from .serverAddress rather
than SessionProxy.Configuration

Also drop useless Equatable implementations.

Davide De Rosa 11fd418f82 Extend encrypted private key quick test 
Test .ovpn didn't use an PKCS#8 key due to a slip-up. Fixing it
