IPVS: init and cleanup restructuring

2011-05-10T07:52:47Z

DESCRIPTION This patch tries to restore the initial init and cleanup sequences that was before namspace patch. Netns also requires action when net devices unregister which has never been implemented. I.e this patch also covers when a device moves into a network namespace, and has to be released. IMPLEMENTATION The number of calls to register_pernet_device have been reduced to one for the ip_vs.ko Schedulers still have their own calls. This patch adds a function __ip_vs_service_cleanup() and an enable flag for the netfilter hooks. The nf hooks will be enabled when the first service is loaded and never disabled again, except when a namespace exit starts.

IPVS: fix NULL ptr dereference in ip_vs_ctl.c ip_vs_genl_dump_daemons()

2011-04-04T13:25:18Z

ipvsadm -ln --daemon will trigger a Null pointer exception because ip_vs_genl_dump_daemons() uses skb_net() instead of skb_sknet(). To prevent others from NULL ptr a check is made in ip_vs.h skb_net(). Signed-off-by: Hans Schillstrom Signed-off-by: Simon Horman Signed-off-by: Patrick McHardy

IPVS: Use global mutex in ip_vs_app.c

2011-03-22T03:39:24Z

As part of the work to make IPVS network namespace aware __ip_vs_app_mutex was replaced by a per-namespace lock, ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes. Unfortunately this implementation results in ipvs->app_key residing in non-static storage which at the very least causes a lockdep warning. This patch takes the rather heavy-handed approach of reinstating __ip_vs_app_mutex which will cover access to the ipvs->list_head of all network namespaces.
