From fd466e068e5adef5922b76f24374c96ba01faaa2 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 4 Apr 2017 16:50:45 -0700 Subject: [PATCH] randstruct: Whitelist struct security_hook_heads cast MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The LSM initialization routines walk security_hook_heads as an array of struct list_head instead of via names to avoid a ton of needless source. Whitelist this to avoid the false positive warning from the plugin: security/security.c: In function ‘security_init’: security/security.c:59:20: note: found mismatched op0 struct pointer types: ‘struct list_head’ and ‘struct security_hook_heads’ struct list_head *list = (struct list_head *) &security_hook_heads; ^ Cc: Tetsuo Handa Cc: James Morris Signed-off-by: Kees Cook --- scripts/gcc-plugins/randomize_layout_plugin.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/scripts/gcc-plugins/randomize_layout_plugin.c b/scripts/gcc-plugins/randomize_layout_plugin.c index e1d1ba28739f..dc0df3765a8f 100644 --- a/scripts/gcc-plugins/randomize_layout_plugin.c +++ b/scripts/gcc-plugins/randomize_layout_plugin.c @@ -46,6 +46,8 @@ struct whitelist_entry { }; static const struct whitelist_entry whitelist[] = { + /* walk struct security_hook_heads as an array of struct list_head */ + { "security/security.c", "list_head", "security_hook_heads" }, { } }; -- 2.20.1
