Subject: net: ipc_router: Register services only on client port
|
|
|
|
Allowing services to be registered on a non-client port will cause either
|
|
an existing service or a control port to be over-written. This will cause
|
|
undefined functional behavior.
|
|
|
|
Allow the services to be registered only on client ports.
