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 <vmkari@cc.helsinki.fi> Signed-off-by: James Morris <jmorris@namei.org>
