From 89eda06837094ce9f34fae269b8773fcfd70f046 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Sun, 4 Oct 2009 21:49:47 +0900 Subject: LSM: Add security_path_chmod() and security_path_chown(). This patch allows pathname based LSM modules to check chmod()/chown() operations. Since notify_change() does not receive "struct vfsmount *", we add security_path_chmod() and security_path_chown() to the caller of notify_change(). These hooks are used by TOMOYO.
