net: add ability to set names for outside links of veth devices When restoring a container crtools create veth pair inside it and then pushed one end to the namespaces crtools live in (outside). To facilitate the subsequent management of the otter end of the veth pair this option is added -- one can specifu a name by which the respective end would be visible.

netns: Basic link dump, restore and show Only support the lo device. This is not final yet (much more stuff is to be handled for a link) but is rather a skeleton showing how to do it and letting us check the LXC container early.

net: Push the host end of a veth to original netns The call will then have to handle this end (put into a bridge). Signed-off-by: Pavel Emelyanov <xemul@parallels.com> 2012-08-10 19:14:36 +04:00			`int netns_pre_create(void);`

headers: Unify include guards (in comments) and a few fixes - fix names in comments - add empty lines where needed - fix rbtree.h - fix syscall-types.h Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@parallels.com> 2012-12-25 22:40:24 +04:00
ns: Introduce ns descriptors These are structs that (now) tie together ns string and the CLONE_ flag. It's nice to have one (some code becomes simpler) and will help us with auto-namespaces detection.
