Subject: wlan:Check priviledge permission for SET_VAR_INTS_GETNONE 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_VAR_INTS_GETNONE, making
|
|
sure user task has right permission to process the command.
