This reverts commit 64506929. While the code does not actually break anything, it does not completely follow RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better implemented in userspace. The kernel should not send RS packages for ISATAP at all. Signed-off-by: NSascha Hlusiak <contact@saschahlusiak.de> Acked-by: NFred L. Templin <Fred.L.Templin@boeing.com> Signed-off-by: NDavid S.

It seems recursion field from "struct ip_tunnel" is not anymore needed. recursion prevention is done at the upper level (in dev_queue_xmit()), since we use HARD_TX_LOCK protection for tunnels. This avoids a cache line ping pong on "struct ip_tunnel" : This structure should be now mostly read on xmit and receive paths.

if tunnel parameters have frag_off set to IP_DF, pmtudisc on the ipv4 link will be performed by deriving the mtu from the ipv4 link and setting the DF-Flag of the encapsulating IPv4 Header. If fragmentation is needed on the way, the IPv4 pmtu gets adjusted, the ipv6 package will be resent eventually, using the new and lower mtu and everyone is happy. If the frag_off parameter is unset, the mtu for the tunnel will be derived from the tunnel device or the ipv6 pmtu, which might be higher than the ipv4 pmtu. In that case we must allow the fragmentation of the IPv4 packet because the IPv6 mtu wouldn't 'learn' from the adjusted IPv4 pmtu, resulting in frequent icmp_frag_needed and package loss on the IPv6 layer. This patch allows fragmentation when tunnel was created with parameter nopmtudisc, like in ipip/gre tunnels. Signed-off-by: NSascha Hlusiak <contact@saschahlusiak.de> Signed-off-by: NDavid S.

The sit module makes use of skb->dst in it's xmit function, so since 93f154b5 ("net: release dst entry in dev_hard_start_xmit()") sit tunnels are broken, because the flag IFF_XMIT_DST_RELEASE is not unset.

dev_net_set() should be the very first thing after alloc_netdev(). "ndo_" changes turned simple assignment (which is OK to do before netns assignment) into quite non-trivial operation (which is not OK, init_net was used).

Four tunnel drivers (ip_gre, ipip, ip6_tunnel and sit) can receive a pre-defined name for a device from the userspace. Since these drivers call the register_netdevice() (rtnl_lock, is held), which does _not_ generate the device's name, this name may contain a '%' character. Not sure how bad is this to have a device with a '%' in its name, but all the other places either use the register_netdev(), which call the dev_alloc_name(), or explicitly call the dev_alloc_name() before registering, i.e. do not allow for such names. This had to be prior to the commit 34cc7b, but I forgot to number the patches and this one got lost, sorry. Signed-off-by: NPavel Emelyanov <xemul@openvz.org> Signed-off-by: NDavid S.

This is similar to the change already done for IPIP tunnels. Once created, a SIT tunnel can't be bound to another device. To reproduce: # create a tunnel: ip tunnel add tunneltest0 mode sit remote 10.0.0.1 dev eth0 # try to change the bounding device from eth0 to eth1: ip tunnel change tunneltest0 dev eth1 # show the result: ip tunnel show tunneltest0 tunneltest0: ipv6/ip remote 10.0.0.1 local any dev eth0 ttl inherit Notice the bound device has not changed from eth0 to eth1.
