Subject: wlan:Check priviledge permission
|
||
|
|
|
||
|
|
for SET_BAND_CONFIG IOCTL
|
||
|
|
|
||
|
|
Kernel assumes all SET IOCTL commands are assigned with even
|
||
|
|
numbers. But in our WLAN driver, some SET IOCTLS are assigned with
|
||
|
|
odd numbers. This leads kernel fail to check, for some SET IOCTLs,
|
||
|
|
whether user has the right permission to do SET operation.
|
||
|
|
Hence, in driver, before processing SET_BAND_CONFIG IOCTL, making
|
||
|
|
sure user task has right permission to process the command.
