From 13b287e8d1cad951634389f85b8c9b816bd3bb1e Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Thu, 7 Jan 2016 16:38:43 +0200 Subject: ipv4: Namespaceify tcp_keepalive_time sysctl knob Different net namespaces might have different requirements as to the keepalive time of tcp sockets. This might be required in cases where different firewall rules are in place which require tcp timeout sockets to be increased/decreased independently of the host.
