From e6a1f7e0b0fe5997b896b793c70d12fc5ed06cdd Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Wed, 4 Aug 2021 16:18:50 -0500 Subject: net/ipv4/igmp: Use struct_size() helper Replace IP_SFLSIZE() with struct_size() helper in order to avoid any potential type mistakes or integer overflows that, in the worst scenario, could lead to heap overflows.
