From: Kurt Garloff <[EMAIL PROTECTED]> Subject: Clean LSM stub file References: 40217, 39439
Rather than having every LSM hook twice, once for the case with CONFIG_SECURITY enabled and once for the disabled case, put everything in one inline function. This reduces the chance of the two to go out of sync immensely. This is patch 2/5 of the LSM overhaul. security.h | 1268 ++++++++++++++++--------------------------------------------- 1 files changed, 337 insertions(+), 931 deletions(-) Signed-off-by: Kurt Garloff <[EMAIL PROTECTED]> Index: linux-2.6.10/include/linux/security.h =================================================================== --- linux-2.6.10.orig/include/linux/security.h +++ linux-2.6.10/include/linux/security.h @@ -1242,1543 +1242,949 @@ struct security_operations { /* global variables */ extern struct security_operations *security_ops;
