Hi, Jan, I am a bit confused about the rtdm_recvmsg_lxrt and rtdm_sendmsg_lxrt functions. In the implementation, the first copy_from_user seems transfer the "msg" from user space to kernel space "krnl_msg", but then in the next rtdm_xxx kernel fucntion call, still the original "msg" is used, why and how is the krnl_msg used in this case?
And the RTDM_USER_MODE_CALL is used in rtdm_xxx to indicate the call from user space, but then I could not find out how RTDM_USER_MODE_CALL is used in udp's functions, e.g. rt_udp_sendmsg/recvmsg. Does udp support rtdm send/recvmsg call from user space?
