Casts __kernel to __user pointer require __force markup, so add it. Also sock_get/setsockopt() takes @optval and/or @optlen arguments as user pointers but were taking kernel pointers, use new variables 'uoptval' and/or 'uoptlen' to fix it. These remove following warnings from sparse: net/socket.c:1922:46: warning: cast adds address space to expression (<asn:1>) net/socket.c:3061:61: warning: incorrect type in argument 4 (different address spaces) net/socket.c:3061:61: expected char [noderef] <asn:1>*optval net/socket.c:3061:61: got char *optval net/socket.c:3061:69: warning: incorrect type in argument 5 (different address spaces) net/socket.c:3061:69: expected int [noderef] <asn:1>*optlen net/socket.c:3061:69: got int *optlen net/socket.c:3063:67: warning: incorrect type in argument 4 (different address spaces) net/socket.c:3063:67: expected char [noderef] <asn:1>*optval net/socket.c:3063:67: got char *optval net/socket.c:3064:45: warning: incorrect type in argument 5 (different address spaces) net/socket.c:3064:45: expected int [noderef] <asn:1>*optlen net/socket.c:3064:45: got int *optlen net/socket.c:3078:61: warning: incorrect type in argument 4 (different address spaces) net/socket.c:3078:61: expected char [noderef] <asn:1>*optval net/socket.c:3078:61: got char *optval net/socket.c:3080:67: warning: incorrect type in argument 4 (different address spaces) net/socket.c:3080:67: expected char [noderef] <asn:1>*optval net/socket.c:3080:67: got char *optval Signed-off-by: Namhyung Kim <namhyung@gmail.com> Signed-off-by: David S.
