Primary Changes:
- Remove reliance on Private Key PEM:
- Update native and keygen packages to return PrivateKey instead of PEM key
- Add new PrivateKey interface which implements crypto.Signer
- Replace PEM encoded private key usage where possible
- Replace calls to tls.(Load)X509KeyPair with keys.(Load)X509KeyPair in
client packages
Minor Changes:
- Remove unused agent.AddedKey return from LoadKey
- Simplify sshutils and removed unused code paths
- Add ecdsa and ed25519 key support
* Add additional debug logging for instantiation of ssh server conn
* Rough out introducing mux to ssh listener
* Catch errors from multiplexer serve
* Adapt multiplexer to support ProxyHelloSignature
* Adjust logging for ssh conn creation
* Adjust tests to use semantically correct assert/require helpers
* Address PR comments
* Check Client addr is properly propagated in mux test
* Add tracing instrumentation for ssh clients/servers
Add tracing context to the existing ProxyHelloSignature to provide
span information across ssh connections. To add span context per
ssh session on top of new connections, the same tracing context is
passed in the first global request of the session.
In order to ensure that tracing context is pulled from and inserted
into the proper context.Context, some interfaces and methods were
changed to take one as the first argument.
Load access requests from SSH cert instead of the profile. The profile
only exists on CLI clients, but not in the proxy.
Note: theoretically, SSH cert may be missing in some cases for CLI
clients. We should eventually encode access requests in TLS certs too,
which are always present.
* Added support for connecting API client through tunnel proxy and web proxy addresses (with identity file).
* Added concurrent dialing logic to dial several possible dialing combinations and seamlessly return the first client to connect.
