From e3e2775cedc9d6294b7bc7cbe9f59c62f9472871 Mon Sep 17 00:00:00 2001 From: Nickolai Zeldovich Date: Wed, 16 Jan 2013 21:36:17 -0500 Subject: [PATCH] cifs: fix srcip_matches() for ipv6 srcip_matches() previously had code like this: srcip_matches(..., struct sockaddr *rhs) { /* ... */ struct sockaddr_in6 *vaddr6 = (struct sockaddr_in6 *) &rhs; return ipv6_addr_equal(..., &vaddr6->sin6_addr); } which interpreted the values on the stack after the 'rhs' pointer as an ipv6 address. The correct thing to do is to use 'rhs', not '&rhs'.
