From 1f2aab8aaaa5f3a5d1bd712173187c92986f753b Mon Sep 17 00:00:00 2001 From: David Gibson Date: Fri, 8 Dec 2023 01:31:33 +1100 Subject: [PATCH] tcp: Fix address type for tcp_sock_init_af() This takes a struct in_addr * (i.e. an IPv4 address), although it's explicitly supposed to handle IPv6 as well. Both its caller and sock_l4() which it calls use a void * for the address, which can be either an in_addr or an in6_addr. We get away with this, because we don't do anything with the pointer other than transfer it from the caller to sock_l4(), but it's misleading. And quite possibly technically UB, because C is like that.
