To prevent users from being able to directly connect to registered
OpenSSH (Agentless) nodes, the OpenSSH CA was introduced. When
connecting to Agentless nodes, the Proxy will forward the connection
so the session can be recorded. The forwarding SSH server is configured
to authenticate to the target node with a certificate signed by OpenSSH
CA, which users do not have access to.
The Okta service and client have been introduced. This will allow for the
maintenance of Okta objects via our gRPC server and auth client. Some
additional improvements have been made so that the local okta service now
better reflects the gRPC definition.
Additionally, the gRPC authorization mechanism has been lifted out of
`lib/auth/grpcserver.go` and moved into a common authorizer. Finally, the
ability to check access to verbs has been lifted out of the `pluginsv1`
service into that same authorizer. This will hopefully provide a good base
for separate gRPC services in the future.
Adds a new `GetCertAuthorities` unary RPC to
`teleport.v1.trust.TrustService` and deprecates the equivalent
HTTP endpoint. All associated interfaces have been updated to remove
the marshal options as well.
This PR removes the `types.KindKubeService` objects that were
deprecated in Teleport 11.
Teleport 12 removed the double heartbeat and for Teleport 13 we can
safely drop the support of the old hearbeat based on `types.Server`
objects.
Clients older than Teleport 12 connecting to a Teleport 13 server will
fail since they cannot heartbeat using the old mechanism.
Now that the authorizer has been moved to the `authz` package, the
permissions alias has been removed. Additionally, the `contextKey` in
`permissions.go` has been unexported.
The HTTP client created by `auth.NewClient` has an idle timeout of
30s and each instance periodically gets cert authorities in
`TeleportProcess.syncRotationStateCycle`. If there has been no
activity when the ticker expires then the request will result in a
brand new connection to Auth to be established. This can cause a
spikes in open file descriptors on the Proxy when there are a large
number of instances connected via a tunnel.
To prevent periodic dialing when retrieving cert authorities the
endpoint has been migrated to the new Trust gRPC service. For now
only the get endpoint has been migrated but the rest of the CRUD
operations for cert authorities should be migrated from the HTTP
api to the gRPC service as well.
* Move the authorizer into its own package.
The Authorizer and associated functions and constants have been moved into
their own package `authz`. This will allow us to more easily create separate
services for gRPC functionality so that we're not pushing as much into the
`lib/auth` package.
Though this PR is large, the only actual code change here is making
`ContextForLocalUser` exported and changing the `permissions_test.go` so that
it doesn't rely on the `lib/auth` package.
* Use context functions.
* Test and linting fixes.
* Add in a temporary alias file to ensure e still compiles.
* Use functions instead of var aliases for performance reasons.
* Adding in godocs, cleaning up tests.
* Fix tests.
* Add a few more aliases.
