From d12d01d6b4d197115c4d7736172b5b1ec8b1eb71 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Mon, 19 Nov 2007 22:28:35 -0800 Subject: [NET]: Make AF_PACKET handle multiple network namespaces This is done by making packet_sklist_lock and packet_sklist per network namespace and adding an additional filter condition on received packets to ensure they came from the proper network namespace. Changes from v1: - prohibit to call inet_dgram_ops.ioctl in other than init_net Signed-off-by: Denis V. Lunev Signed-off-by: Eric W. Biederman Signed-off-by: David S.
