e01a2bc729 Added pprof to convergeserver and optionally to
the agent if PPROF_PORT is set.

Fixed issue with converge server not cleaning up goroutines because of blocking channel. Made sure to create channels with > 1 size everywhere it can be done. The blocking behavior of a default channel size is mostly in the way.

Known issue: Killing the SSH client will lead to the server side process not being terminated and some goroutines still running in the agent. This would require additional investigation to solve. The remote processes are still being cleaned up ok (at least on linux) when the agent exits.

This should not be an issue at all since the agent is a short-lived process and when running in a containerized environment with containers running on demand the cleanup will definitely work.

788050df32 Unique ids for clients generated by converge server and made available to the ssh session through a net.Conn extension that passes the ID to the SSH session through the LocalAddr(). 2024-09-08 11:16:49 +02:00
9d0675b2f2 initialization of username, password on client (from server) and initialization of agentinfo on server is now done as soon as the agent registered and not through a side channel.
Making use of some simple utilities for GOB to make it easy to send objects over the line.
2024-09-08 11:16:49 +02:00
ada34495ef GOB channel for easily and asynchronously using GOB on a single network connection, also dealing with timeouts and errors in a good way.
Protocol version is now checked when the agent connects to the converge server.

Next up: sending connection metadata and username password from server to agent and sending environment information back to the server. This means then that the side channel will only be used for expiry time messages and session type with the client id passed in so the converge server can than correlate the results back to the correct channel.

d3cbf8388f Lots of refactoring.
Now hijacking the ssh connection setup in the listener to exchange some information before passing the connection on to the SSH server.

Next step is to do the full exchange of required information and to make it easy some simple Read and Write methods with timeouts are needed that use gob.
