linux-user: add ioctl(SIOCGIWNAME, ...) support.
Allow to run properly following program from linux-user: /* cc -o wifi wifi.c */ #include <stdio.h> #include <sys/ioctl.h> #include <sys/types.h> #include <sys/socket.h> #include <linux/wireless.h> #include <netinet/in.h> #include <arpa/inet.h> #include <string.h> int main(int argc, char **argv) { int ret; struct ifreq req; struct sockaddr_in *addr; int s; if (argc != 2) { fprintf(stderr, "Need an interface name (like wlan0)\n"); return 1; } s = socket( AF_INET, SOCK_DGRAM, 0 ); if (s < 0) { perror("Cannot open socket"); return 1; } strncpy(req.ifr_name, argv[1], sizeof(req.ifr_name)); ret = ioctl( s, SIOCGIWNAME, &req ); if (ret < 0) { fprintf(stderr, "No wireless extension\n"); return 1; } printf("%s\n", req.ifr_name); printf("%s\n", req.ifr_newname); return 0; } $ ./wifi eth0 No wireless extension $ ./wifi wlan0 wlan0 IEEE 802.11bg Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
