ipc: add protected payload
Add a field ip_protected_payload and a flag ip_has_protected_payload
to struct ipc_port.
Clear the protected payload when a receive port is moved from one ipc
space to another. This is done to retain the old behavior of
mach_msg, so that a port name is sent in the msgh_local_port field.
If the new owner of that receive right wishes to use the protected
payload mechanism, it has to be explicitly set again.
* ipc/ipc_port.h (struct ipc_port): Add field ip_protected_payload.
(ipc_port_set_protected_payload): Add function declaration.
(ipc_port_clear_protected_payload): Likewise.
(ipc_port_flag_protected_payload): Add accessor for the protected
payload flag.
(ipc_port_flag_protected_payload_set): Likewise.
(ipc_port_flag_protected_payload_clear): Likewise.
* ipc/ipc_port.c (ipc_port_init): Initialize protected payload.
(ipc_port_print): Print protected_payload.
(ipc_port_set_protected_payload): New function.
(ipc_port_clear_protected_payload): Likewise.
(ipc_port_destroy): Clear the payload when moving a receive port.
* ipc/ipc_right.c (ipc_right_copyin): Likewise.
(ipc_right_copyout): Likewise.
* ipc/ipc_object.c (ipc_object_copyin_from_kernel): Likewise.
* ipc/ipc_object.h (IO_BITS_PROTECTED_PAYLOAD): New bitmask.
(IO_BITS_OTYPE): Adjust accordingly.
