I have been looking into your suggestions and I have some questions about it.

I assume here the session() method inherited from Genode::Root has to be implemented such that it returns the capability that is the Slave::Connection after that connection has been initiated?

Here, you create a Forwarded_capability struct, which wraps a session capability. It inherits from Id_space<Parent::Client>::Element. Why if I may ask? Do I need to do that too? It eventually invokes env.session() to create a new capability for the forwarded service. Why does it not get its capability from the server, but instead seems to create a new session for a certain service? It seems to me that the Service router does not forward capabilities from children, or am I wrong? Does the cap live somewhere else? I'm missing the picture a bit here. Can you explain how it works with those capabilities? -- Met vriendelijke groet / kind regards, Boris Mulder Cyber Security Labs B.V. | Gooimeer 6-31 | 1411 DD Naarden | The Netherlands +31 35 631 3253 (office) ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ genode-main mailing list genode-main@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/genode-main
