From 10f47e6a1b8b276323b652053945c87a63a5812d Mon Sep 17 00:00:00 2001 From: Stephen Smalley Date: Fri, 9 Sep 2005 13:01:39 -0700 Subject: [PATCH] ext2: Enable atomic inode security labeling This patch modifies ext2 to call the inode_init_security LSM hook to obtain the security attribute for a newly created inode and to set the resulting attribute on the new inode. This parallels the existing processing for setting ACLs on newly created inodes.
