From 1fac73337080712109029302599945d1ac36c799 Mon Sep 17 00:00:00 2001 From: Mukul Sharma Date: Thu, 17 Mar 2016 09:55:27 -0700 Subject: wlan:Check priviledge permission before processing for SET_OEM_DATA_REQ 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_OEM_DATA_REQ IOCTLs, making sure user task has right permission to process the command.
