2013-08-21Merge branch 'tuntap'David S. Miller
Pavel Emelyanov says: ==================== tun: Some bits required for tun's checkpoint-restore (v2) After taking a closer look on tun checkpoint-restore I've found several issues with the tun's API that make it impossible to dump and restore the state of tun device and attached tun-files. The proposed API changes are all about extending the existing ioctl-based stuff. Patches fit today's net-next. This v2 has David's comments about patch #1 fixed. All the rest is the same. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2013-08-21tun: Get skfilter layoutPavel Emelyanov
The only thing we may have from tun device is the fprog, whic contains the number of filter elements and a pointer to (user-space) memory where the elements are. The program itself may not be available if the device is persistent and detached. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-08-21tun: Allow to skip filter on attachPavel Emelyanov
There's a small problem with sk-filters on tun devices. Consider an application doing this sequence of steps: fd = open("/dev/net/tun"); ioctl(fd, TUNSETIFF, { .ifr_name = "tun0" }); ioctl(fd, TUNATTACHFILTER, &my_filter); ioctl(fd, TUNSETPERSIST, 1); close(fd); At that point the tun0 will remain in the system and will keep in mind that there should be a socket filter at address '&my_filter'. If after that we do fd = open("/dev/net/tun"); ioctl(fd, TUNSETIFF, { .ifr_name = "tun0" }); we most likely receive the -EFAULT error, since tun_attach() would try to connect the filter back. But (!) if we provide a filter at address &my_filter, then tun0 will be created and the "new" filter would be attached, but application may not know about that. This may create certain problems to anyone using tun-s, but it's critical problem for c/r -- if we meet a persistent tun device with a filter in mind, we will not be able to attach to it to dump its state (flags, owner, address, vnethdr size, etc.). The proposal is to allow to attach to tun device (with TUNSETIFF) w/o attaching the filter to the tun-file's socket. After this attach app may e.g clean the device by dropping the filter, it doesn't want to have one, or (in case of c/r) get information about the device with tun ioctls.

2013-08-21tun: Add ability to create tun device with given indexPavel Emelyanov
Tun devices cannot be created with ifidex user wants, but it's required by checkpoint-restore project. Long time ago such ability was implemented for rtnl_ops-based interface for creating links (9c7dafbf net: Allow to create links with given ifindex), but the only API for creating and managing tuntap devices is ioctl-based and is evolving with adding new ones (cde8b15f tuntap: add ioctl to attach or detach a file form tuntap device). Following that trend, here's how a new ioctl that sets the ifindex for device, that _will_ be created by TUNSETIFF ioctl looks like. So those who want a tuntap device with the ifindex N, should open the tun device, call ioctl(fd, TUNSETIFINDEX, &N), then call TUNSETIFF. If the index N is busy, then the register_netdev will find this out and the ioctl would be failed with -EBUSY. If setifindex is not called, then it will be generated as before.

2013-08-20ip6_tunnel: ensure to always have a link local addressNicolas Dichtel
When an Xin6 tunnel is set up, we check other netdevices to inherit the link- local address. If none is available, the interface will not have any link-local address. RFC4862 expects that each interface has a link local address. Now than this kind of tunnels supports x-netns, it's easy to fall in this case (by creating the tunnel in a netns where ethernet interfaces stand and then moving it to a other netns where no ethernet interface is available). RFC4291, Appendix A suggests two methods: the first is the one currently implemented, the second is to generate a unique identifier, so that we can always generate the link-local address. Let's use eth_random_addr() to generate this interface indentifier. I remove completly the previous method, hence for the whole life of the interface, the link-local address remains the same (previously, it depends on which ethernet interfaces were up when the tunnel interface was set up).
