treewide: Use struct_size() for devm_kmalloc() and friends
Replaces open-coded struct size calculations with struct_size() for devm_*, f2fs_*, and sock_* allocations. Automatically generated (and manually adjusted) from the following Coccinelle script: // Direct reference to struct field. @@ identifier alloc =~ "devm_kmalloc|devm_kzalloc|sock_kmalloc|f2fs_kmalloc|f2fs_kzalloc"; expression HANDLE; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(HANDLE, sizeof(*VAR) + COUNT * sizeof(*VAR->ELEMENT), GFP) + alloc(HANDLE, struct_size(VAR, ELEMENT, COUNT), GFP) // mr = kzalloc(sizeof(*mr) + m * sizeof(mr->map[0]), GFP_KERNEL); @@ identifier alloc =~ "devm_kmalloc|devm_kzalloc|sock_kmalloc|f2fs_kmalloc|f2fs_kzalloc"; expression HANDLE; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(HANDLE, sizeof(*VAR) + COUNT * sizeof(VAR->ELEMENT[0]), GFP) + alloc(HANDLE, struct_size(VAR, ELEMENT, COUNT), GFP) // Same pattern, but can't trivially locate the trailing element name, // or variable name. @@ identifier alloc =~ "devm_kmalloc|devm_kzalloc|sock_kmalloc|f2fs_kmalloc|f2fs_kzalloc"; expression HANDLE; expression GFP; expression SOMETHING, COUNT, ELEMENT; @@ - alloc(HANDLE, sizeof(SOMETHING) + COUNT * sizeof(ELEMENT), GFP) + alloc(HANDLE, CHECKME_struct_size(&SOMETHING, ELEMENT, COUNT), GFP) Signed-off-by: Kees Cook <keescook@chromium.org>
