[Devel] [PATCH vz7 0/2] Port SIOCGSKNS support for sockets and tun

[Kirill Tkhai]

This patchset ports get-socket-and-tun-net-namespace-fd functionality
from mainline kernel to vz7.

Note, that in case of sockets and tun we don't have proc vfsmnt
like we have for NS_GET_USERNS and NS_GET_PARENT. The workaround
is to use current's pid_ns->proc_mnt. It has to work even in case
of nested pid ns, since the namespaces inodes numbers are uniqul
in the system.

      tun: Add ioctl() SIOCGSKNS cmd to allow obtaining net ns of tun device
