Hi All,

As far as I understand, in seL4, the notion of a subject is similar to a thread (process). Each process has a different cspace and thus has different capabilities. Correct me, if I am wrong.

Currently, we can make different components say server and client which run on the same seL4 kernel. They can interact with each other by creating endpoint and adding capability for that endpoint, in others cspace.

Now, I want to extend it and run client and server on different host machines which run seL4. The threads (client and server) thus generated will be different users as per the standard linux convention.

a) How does the communication happen in such a scenario in seL4? The problem which I see is how the capabilities for endpoint on one machine will be minted into other machine's process cspace. b) I also want to understand the notion of a user in seL4.
