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