From e4dca7b7aa08b22893c45485d222b5807c1375ae Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 17 Oct 2017 19:04:42 -0700 Subject: treewide: Fix function prototypes for module_param_call() Several function prototypes for the set/get functions defined by module_param_call() have a slightly wrong argument types. This fixes those in an effort to clean up the calls when running under type-enforced compiler instrumentation for CFI. This is the result of running the following semantic patch: @match_module_param_call_function@ declarer name module_param_call; identifier _name, _set_func, _get_func; expression _arg, _mode; @@ module_param_call(_name, _set_func, _get_func, _arg, _mode); @fix_set_prototype depends on match_module_param_call_function@ identifier match_module_param_call_function._set_func; identifier _val, _param; type _val_type, _param_type; @@ int _set_func( -_val_type _val +const char * _val , -_param_type _param +const struct kernel_param * _param ) { ... } @fix_get_prototype depends on match_module_param_call_function@ identifier match_module_param_call_function._get_func; identifier _val, _param; type _val_type, _param_type; @@ int _get_func( -_val_type _val +char * _val , -_param_type _param +const struct kernel_param * _param ) { ... } Two additional by-hand changes are included for places where the above Coccinelle script didn't notice them: drivers/platform/x86/thinkpad_acpi.c fs/lockd/svc.c Signed-off-by: Kees Cook Signed-off-by: Jessica Yu --- drivers/android/binder.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/android/binder.c') diff --git a/drivers/android/binder.c b/drivers/android/binder.c index 0621a95b8597..c45157d71b33 100644 --- a/drivers/android/binder.c +++ b/drivers/android/binder.c @@ -150,7 +150,7 @@ static DECLARE_WAIT_QUEUE_HEAD(binder_user_error_wait); static int binder_stop_on_user_error; static int binder_set_stop_on_user_error(const char *val, - struct kernel_param *kp) + const struct kernel_param *kp) { int ret; -- cgit v1.2.3
