From e0df02e0c2118892b302e8248dbbb21698bedfed Mon Sep 17 00:00:00 2001 From: Craig Gallek Date: Wed, 17 Jun 2015 10:59:10 -0400 Subject: sock_diag: fetch source port from inet_sock When an inet_sock is destroyed, its source port (sk_num) is set to zero as part of the unhash procedure. In order to supply a source port as part of the NETLINK_SOCK_DIAG socket destruction broadcasts, the source port number must be read from inet_sport instead.
