Secure RPC messaging¶
Background¶
Trove uses oslo_messaging.rpc for communication amongst the various control plane components and the guest agents. For secure operation of the system, these RPC calls can be fully encrypted. A control plane encryption key is used for communications between the API service and the taskmanager, and system generated per-instance keys are used for communication between the control plane and guest instances.
This document provides some useful tips on how to use this mechanism.
The default system behavior¶
By default, the system will attempt to encrypt all RPC communication. This behavior is controlled by the following configuration parameters:
enable_secure_rpc_messaging
boolean that determines whether rpc messages will be secured by encryption. The default value is True.
taskmanager_rpc_encr_key
the key used for encrypting messages sent to the taskmanager. A default value is provided for this and it is important that deployers change this.
inst_rpc_key_encr_key
the key used for encrypting the per-instance keys when they are stored in the trove infrastructure database (catalog). A default is provided for this and it is important that deployers change this.
Interoperability and Upgrade¶
Consider the system as shown below which runs a version of code prior to the introduciton of this oslo_messaging.rpc security. Observe, for example that the instances table in the system catalog does not include the per-instance encrypted key column:

We launch an instance of MySQL using this version of the software:

And on that machine, the configuration file looks like this:

For testing later, we launch a few more instances:
amrith@amrith-work:/opt/stack/trove/integration/scripts$ trove create m3 25 --size 3 --nic net-id=4bab02e7-87bb-4cc0-8c07-2f282c777c85

+--------------------------------------+------+-----------+-------------------+--------+-----------+------+-----------+
In this condition, we take down the control plane and upgrade the software running on it. This will result in a catalog upgrade. Since this system is based on devstack, here’s what that looks like:
amrith@amrith-work:/opt/stack/trove$ git branch

We can now relaunch the control plane software but before we do that, we inspect the configuration parameters and disable secure RPC messaging by adding this line into the configuration files:
amrith@amrith-work:/etc/trove$ grep enable_secure_rpc_messaging *.conf
trove.conf:enable_secure_rpc_messaging = False

At this point communication between API service and Task Manager, and between the control plane and instance m20 is encrypted but communication between control plane and all other instances is not encrypted.
In this condition we can attempt some operations on the various instances. First with the legacy instances created on software that predated the secure RPC mechanism:
amrith@amrith-work:/etc/trove$ trove database-list m2
+------+
| Name |
+------+
+------+
amrith@amrith-work:/etc/trove$ trove database-create m2 foo2
amrith@amrith-work:/etc/trove$ trove database-list m2
+------+
| Name |
+------+
| foo2 |
+------+
And at the same time with the instance m10 which is created with the current software but without RPC encryption:
amrith@amrith-work:/etc/trove$ trove database-list m10
+------+
| Name |
+------+
+------+
amrith@amrith-work:/etc/trove$ trove database-create m10 foo10
amrith@amrith-work:/etc/trove$ trove database-list m10
+-------+
| Name |
+-------+
| foo10 |
+-------+
amrith@amrith-work:/etc/trove$
And finally with an instance that uses encrypted RPC communications:
amrith@amrith-work:/etc/trove$ trove database-list m20
+------+
| Name |
+------+
+------+

Finally, we can upgrade an instance that has no encryption to have rpc encryption:

Let’s look at instance m2:
