/proc/sys/net/netfilter/* Variables:

nf_log_all_netns - BOOLEAN
	0 - disabled (default)
	not 0 - enabled

	By default, only init_net namespace can log packets into kernel log
	with LOG target; this aims to prevent containers from flooding host
	kernel log. If enabled, this target also works in other network
	namespaces. This variable is only accessible from init_net.
