Greg Kroah-Hartman 01d00bc035 global: add SPDX tags to all files
It's good to have SPDX identifiers in all files as the Linux kernel
developers are working to add these identifiers to all files.

Update all files with the correct SPDX license identifier based on the license
text of the project or based on the license in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of the
full boiler plate text.

Jason A. Donenfeld b16641e30c wg: first additions of userspace integration
This is designed to work with a server that follows this:

  struct sockaddr_un addr = {
      .sun_family = AF_UNIX,
      .sun_path = "/var/run/wireguard/wguserspace0.sock"
  };
  int fd, ret;
  ssize_t len;
  socklen_t socklen;
  struct wgdevice *device;

  fd = socket(AF_UNIX, SOCK_DGRAM, 0);
  if (fd < 0)
      exit(1);
  if (bind(fd, (struct sockaddr *)&addr, sizeof(addr)) < 0)
      exit(1);

  for (;;) {
      /* First we look at how big the next message is, so we know how much to
       * allocate. Note on BSD you can instead use ioctl(fd, FIONREAD, &len). */
      len = recv(fd, NULL, 0, MSG_PEEK | MSG_TRUNC);
      if (len < 0) {
          handle_error();
          continue;
      }
      /* Next we allocate a buffer for the received data. */
      device = NULL;
      if (len) {
          device = malloc(len);
          if (!device) {
              handle_error();
              continue;
          }
      }
      /* Finally we receive the data, storing too the return address. */
      socklen = sizeof(addr);
      len = recvfrom(fd, device, len, 0, (struct sockaddr *)&addr, (socklen_t *)&socklen);
      if (len < 0) {
          handle_error();
          free(device);
          continue;
      }
      if (!len) { /* If len is zero, it's a "get" request, so we send our device back. */
          device = get_current_wireguard_device(&len);
          sendto(fd, device, len, 0, (struct sockaddr *)&addr, socklen);
      } else { /* Otherwise, we just received a wgdevice, so we should "set" and send back the return status. */
          ret = set_current_wireguard_device(device);
          sendto(fd, &ret, sizeof(ret), 0, (struct sockaddr *)&addr, socklen);
          free(device);
      }
  }
