Linux kernel space and user space network transmission point! Due to a need, caused by the client kernel module form msghdr LKM sent to the server structure of the data; Server space is the ordinary user applications, but the client server data received for the distortion, no matter what transmission characters show for the same distortion go up in smoke. I would like to ask the user space and kernel space network transmission is not what problems need to be considered and resolved. PS : I was sent msghdr sock_sendmsg space in the core data structure, users receive msghdr recvmsg space structure, but the data show is the domain distortion go up in smoke. [ Closed window ]
