Davide De Rosa 6fb409b112 Drop UDP packets on no buffer space available
Tolerate only on data channel. Control channel should never reach
high speeds.

Fixes #87
2019-04-25 17:29:10 +02:00
Davide De Rosa f9f642b64e Set as default gateway based on routing policies
Also fix IPv6 routes not properly set.
2019-04-25 14:39:40 +02:00
Davide De Rosa 65af163aeb Do not resend non-acked packets if reliable
In control channel.
2019-04-23 23:06:39 +02:00
Davide De Rosa 9b8be02c2a Shut down when no IPv4/6 routing available
Would fake-connect without VPN icon otherwise.

Davide De Rosa 887e2ae55d Consider stale if HARD_RESET while connected
Was disconnecting when more than one HARD_RESET_SERVER was
received during negotiation.

Davide De Rosa ad964e2041 Send local options with authentication
Fixes some obsolete servers requiring cipher keysize.
2019-04-15 17:37:57 +02:00
Davide De Rosa 55534df6fa Work around cipher/digest/framing issues
- Make them optional
- Set default values inside SessionProxy

Fallback is not needed anywhere else.

Davide De Rosa 4dc9539260 Rename OptionsError to ConfigurationError 2019-04-04 18:51:06 +02:00
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 9876c81de5 Parse PUSH_REPLY options in OptionsBundle
- auth-token

- Routing

Reorganize options by semantic.

Reuse OptionsBundle in PushReply.
