From f856567b930dfcdbc3323261bf77240ccdde01f5 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 29 Oct 2013 22:11:06 +0300 Subject: [PATCH] aacraid: missing capable() check in compat ioctl In commit d496f94d22d1 ('[SCSI] aacraid: fix security weakness') we added a check on CAP_SYS_RAWIO to the ioctl. The compat ioctls need the check as well.
