From ce4a7d0d48bbaed78ccbb0bafb9229651a40303a Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 10 Jun 2008 12:39:35 -0700 Subject: inet{6}_request_sock: Init ->opt and ->pktopts in the constructor Wei Yongjun noticed that we may call reqsk_free on request sock objects where the opt fields may not be initialized, fix it by introducing inet_reqsk_alloc where we initialize ->opt to NULL and set ->pktopts to NULL in inet6_reqsk_alloc.
