Subject: [Qemu-devel] USB port NULL pointer causes segv
Date: Wed, 17 Aug 2011 18:24:48 +0200	[thread overview]
Message-ID: <4E4BEB50.2080800@rdsoftware.de> (raw)

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
