treewide: Use struct_size() for vmalloc()-family
This only finds one hit in the entire tree, but here's the Coccinelle: // Directly refer to structure's field @@ identifier alloc =~ "vmalloc|vzalloc"; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(sizeof(*VAR) + COUNT * sizeof(*VAR->ELEMENT)) + alloc(struct_size(VAR, ELEMENT, COUNT)) // mr = kzalloc(sizeof(*mr) + m * sizeof(mr->map[0]), GFP_KERNEL); @@ identifier alloc =~ "vmalloc|vzalloc"; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(sizeof(*VAR) + COUNT * sizeof(VAR->ELEMENT[0])) + alloc(struct_size(VAR, ELEMENT, COUNT)) // Same pattern, but can't trivially locate the trailing element name, // or variable name. @@ identifier alloc =~ "vmalloc|vzalloc"; expression SOMETHING, COUNT, ELEMENT; @@ - alloc(sizeof(SOMETHING) + COUNT * sizeof(ELEMENT)) + alloc(CHECKME_struct_size(&SOMETHING, ELEMENT, COUNT)) Signed-off-by: Kees Cook <keescook@chromium.org>
