From d366477a52f1df29fa066ffb18e4e6101ee2ad04 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Tue, 6 Dec 2011 07:58:03 +0000 Subject: sock_diag: Initial skeleton When receiving the SOCK_DIAG_BY_FAMILY message we have to find the handler for provided family and pass the nl message to it. This patch describes an infrastructure to work with such nandlers and implements stubs for AF_INET(6) ones. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
