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 --- net/netfilter/nf_conntrack_core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'net/netfilter/nf_conntrack_core.c') diff --git a/net/netfilter/nf_conntrack_core.c b/net/netfilter/nf_conntrack_core.c index 01130392b7c0..5e50c54e1318 100644 --- a/net/netfilter/nf_conntrack_core.c +++ b/net/netfilter/nf_conntrack_core.c @@ -1940,7 +1940,7 @@ int nf_conntrack_hash_resize(unsigned int hashsize) return 0; } -int nf_conntrack_set_hashsize(const char *val, struct kernel_param *kp) +int nf_conntrack_set_hashsize(const char *val, const struct kernel_param *kp) { unsigned int hashsize; int rc; -- cgit v1.2.3-55-g7522
