User may have two tun devices with the same names in different nets, and there is no way to differ them each other. The patchset adds support for ioctl() cmd SIOCGSKNS for tun devices. It will allow people to obtain net namespace file descriptor like we allow to do that for sockets in general. v2: Add new patch [2/3] to export open_related_ns(). --- Kirill Tkhai (3): net: Make extern and export get_net_ns() net: Export open_related_ns() tun: Add ioctl() SIOCGSKNS cmd to allow obtaining net ns of tun device drivers/net/tun.c | 16 ++++++++++++++-- fs/nsfs.c | 1 + include/linux/socket.h | 2 ++ net/socket.c | 3 ++- 4 files changed, 19 insertions(+), 3 deletions(-) -- Signed-off-by: Kirill Tkhai <ktkhai@...tuozzo.com>
