wan: Missing capability checks in sbni_ioctl()
There are missing capability checks in the following code:
1300 static int
1301 sbni_ioctl( struct net_device *dev, struct ifreq *ifr, int cmd)
1302 {
[...]
1319 case SIOCDEVRESINSTATS :
1320 if( current->euid != 0 ) /* root only */
1321 return -EPERM;
[...]
1336 case SIOCDEVSHWSTATE :
1337 if( current->euid != 0 ) /* root only */
1338 return -EPERM;
[...]
1357 case SIOCDEVENSLAVE :
1358 if( current->euid != 0 ) /* root only */
1359 return -EPERM;
[...]
1372 case SIOCDEVEMANSIPATE :
1373 if( current->euid != 0 ) /* root only */
1374 return -EPERM;
Here's my proposed fix:
Missing capability checks.
