From 421fae06be9e0dac45747494756b3580643815f9 Mon Sep 17 00:00:00 2001 From: Vesa-Matti Kari Date: Wed, 6 Aug 2008 18:24:51 +0300 Subject: selinux: conditional expression type validation was off-by-one expr_isvalid() in conditional.c was off-by-one and allowed invalid expression type COND_LAST. However, it is this header file that needs to be fixed. That way the if-statement's disjunction's second component reads more naturally, "if expr type is greater than the last allowed value" ( rather than using ">=" in conditional.c): if (expr->expr_type <= 0 || expr->expr_type > COND_LAST) Signed-off-by: Vesa-Matti Kari Signed-off-by: James Morris --- security/selinux/ss/conditional.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'security') diff --git a/security/selinux/ss/conditional.h b/security/selinux/ss/conditional.h index 65b9f8366e9..53ddb013ae5 100644 --- a/security/selinux/ss/conditional.h +++ b/security/selinux/ss/conditional.h @@ -28,7 +28,7 @@ struct cond_expr { #define COND_XOR 5 /* bool ^ bool */ #define COND_EQ 6 /* bool == bool */ #define COND_NEQ 7 /* bool != bool */ -#define COND_LAST 8 +#define COND_LAST COND_NEQ __u32 expr_type; __u32 bool; struct cond_expr *next; -- cgit v1.2.3-70-g09d2
