[Qemu-devel] USB port NULL pointer causes segv

[Erik Rull]

Hi all,

in usb-linux.c my qemu crashes in
static int usb_host_open(USBHostDevice *dev, int bus_num, int addr, char 
*port, const char *prod_name, int speed)

because port is NULL.

The line that causes the problem is:
strcpy(dev->port, port);

All Ports are displayed in the qemu monitor info as (null)

when changing the line to:
    if (port)
      strcpy(dev->port, port);
    else
      dev->port[0] = '\0';

everything is fine :-)

Please check this issue and let me know if my workaround is okay.

Best regards,

Erik
