From f9008e4c5c525941967b67777945aa6266ab6326 Mon Sep 17 00:00:00 2001 From: David Quigley Date: Fri, 30 Jun 2006 01:55:46 -0700 Subject: [PATCH] SELinux: extend task_kill hook to handle signals sent by AIO completion This patch extends the security_task_kill hook to handle signals sent by AIO completion. In this case, the secid of the task responsible for the signal needs to be obtained and saved earlier, so a security_task_getsecid() hook is added, and then this saved value is passed subsequently to the extended task_kill hook for use in checking.
