Prasun Maiti 3d5fdff46c wext: Fix 32 bit iwpriv compatibility issue with 64 bit Kernel ... iwpriv app uses iw_point structure to send data to Kernel. The iw_point structure holds a pointer. For compatibility Kernel converts the pointer as required for WEXT IOCTLs (SIOCIWFIRST to SIOCIWLAST). Some drivers may use iw_handler_def.private_args to populate iwpriv commands instead of iw_handler_def.private. For those case, the IOCTLs from SIOCIWFIRSTPRIV to SIOCIWLASTPRIV will follow the path ndo_do_ioctl(). Accordingly when the filled up iw_point structure comes from 32 bit iwpriv to 64 bit Kernel, Kernel will not convert the pointer and sends it to driver. So, the driver may get the invalid data. The pointer conversion for the IOCTLs (SIOCIWFIRSTPRIV to SIOCIWLASTPRIV), which follow the path ndo_do_ioctl(), is mandatory. This patch adds pointer conversion from 32 bit to 64 bit and vice versa, if the ioctl comes from 32 bit iwpriv to 64 bit Kernel.
