I've commit a first userland select() support in both
net_userland_stack.c and userland_ipc.c. Basic tests I made works, but
it's not really a testbed.
As I want to be able to use the BONE notify_select_event() kernel call,
I choose to keep the select notification code into the driver, and add support
to driver and IPC server to handle the core->setsocket_event_callback()
callback mecanism used by our kernelland code version.
Basicly, the net_userland_stack launch a kernel thread at init time to
wait for *callback* message on a port, and we pass the notify port as needed
to userland server when we have at least one socket select()'d.
Same port for all sockets.
