riccardom a9fb4e9f0a Makes Transport just a UDP socket.
Manager owns maps for remoteID <-> remote UDP addr
Engine talks to manager only

riccardom 010f5281ce Removes confirm. Uses next offer to deliver confirmation/ack of previous round
We clock the next Offer initiation to the OnDataPathRekeyed, so we have 2 minutes
ahead of us to do our attempts and stuff before to give up.
On failure, we will know because we will not receive a new answer.. but more importantly
the wg handshake will fail :D

riccardom e88fc05575 Leave signal offer/answer as a pull/push operation not as an actual transport 2026-07-27 17:09:35 +02:00
riccardom 7d2c71f84f Assume two transports: initial "signal" (control plane) one (no data path established yet) + data path one
Define OnDataPathRekeyed event to transition from control plane path to data plane path over the WG tunnel.

Keep confirm ALWAYS on NEW established WG tunnel (posthandshake with rekeying). We keep an active method
irrelevant of the WG handshake (we might decide that the indirect wg handshake is sufficient in the future).

Optimistic commit on responder(when sending answer), while on initiator we set it on getting the answer

riccardom 46d4e4585d Collapse Driver and Manager in one.
- Have just one manager => one lock
 - Session state is needed in driver to => we have it available now.
 - Isomorphically align to rosenpass components and functionality
