Currently we need the IP6_TNL_F_CAP_XMIT capabiltiy to transmit packets through an ipv6 tunnel. This capability is set when the tunnel gets configured, based on the tunnel endpoint addresses. On tunnels with wildcard tunnel endpoints, we need to do the capabiltiy checking on a per packet basis like it is done in the receive path. This patch extends ip6_tnl_xmit_ctl() to take local and remote addresses as parameters to allow for per packet capabiltiy checking.

The fallback device is in ipv6 mode by default. The mode can not be changed in runtime, so there is no way to decapsulate ip4in6 packets coming from various sources without creating the specific tunnel ifaces for each peer. This allows to update the fallback tunnel device, but only the mode could be changed. Usual command should work for the fallback device: `ip -6 tun change ip6tnl0 mode any` The fallback device can not be hidden from the packet receiver as a regular tunnel, but there is no need for synchronization as long as we do single assignment.

Testing xmit_more support with netperf and connected UDP sockets, I found strange dst refcount false sharing. Current handling of IFF_XMIT_DST_RELEASE is not optimal. Dropping dst in validate_xmit_skb() is certainly too late in case packet was queued by cpu X but dequeued by cpu Y The logical point to take care of drop/force is in __dev_queue_xmit() before even taking qdisc lock. As Julian Anastasov pointed out, need for skb_dst() might come from some packet schedulers or classifiers. This patch adds new helper to cleanly express needs of various drivers or qdiscs/classifiers. Drivers that need skb_dst() in their ndo_start_xmit() should call following helper in their setup instead of the prior : dev->priv_flags &= ~IFF_XMIT_DST_RELEASE; -> netif_keep_dst(dev); Instead of using a single bit, we use two bits, one being eventually rebuilt in bonding/team drivers. The other one, is permanent and blocks IFF_XMIT_DST_RELEASE being rebuilt in bonding/team. Eventually, we could add something smarter later.

Automatically generate flow labels for IPv6 packets on transmit. The flow label is computed based on skb_get_hash. The flow label will only automatically be set when it is zero otherwise (i.e. flow label manager hasn't set one). This supports the transmit side functionality of RFC 6438. Added an IPv6 sysctl auto_flowlabels to enable/disable this behavior system wide, and added IPV6_AUTOFLOWLABEL socket option to enable this functionality per socket. By default, auto flowlabels are disabled to avoid possible conflicts with flow label manager, however if this feature proves useful we may want to enable it by default. It should also be noted that FreeBSD has already implemented automatic flow labels (including the sysctl and socket option). In FreeBSD, automatic flow labels default to enabled. Performance impact: Running super_netperf with 200 flows for TCP_RR and UDP_RR for IPv6. Note that in UDP case, __skb_get_hash will be called for every packet with explains slight regression. In the TCP case the hash is saved in the socket so there is no regression.

In order to enable lockdep on seqcount/seqlock structures, we must explicitly initialize any locks. The u64_stats_sync structure, uses a seqcount, and thus we need to introduce a u64_stats_init() function and use it to initialize the structure. This unfortunately adds a lot of fairly trivial initialization code to a number of drivers. But the benefit of ensuring correctness makes this worth while. Because these changes are required for lockdep to be enabled, and the changes are quite trivial, I've not yet split this patch out into 30-some separate patches, as I figured it would be better to get the various maintainers thoughts on how to best merge this change along with the seqcount lockdep enablement.

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).

This patch allows to switch the netns when packet is encapsulated or decapsulated. In other word, the encapsulated packet is received in a netns, where the lookup is done to find the tunnel. Once the tunnel is found, the packet is decapsulated and injecting into the corresponding interface which stands to another netns. When one of the two netns is removed, the tunnel is destroyed.

This patch reports the change made by Stephen Hemminger in ipip and gre[6] in commit eccc1bb8 (tunnel: drop packet if ECN present with not-ECT). Goal is to handle RFC6040, Section 4.2: Default Tunnel Egress Behaviour. o If the inner ECN field is Not-ECT, the decapsulator MUST NOT propagate any other ECN codepoint onwards. This is because the inner Not-ECT marking is set by transports that rely on dropped packets as an indication of congestion and would not understand or respond to any other ECN codepoint [RFC4774]. Specifically: * If the inner ECN field is Not-ECT and the outer ECN field is CE, the decapsulator MUST drop the packet. * If the inner ECN field is Not-ECT and the outer ECN field is Not-ECT, ECT(0), or ECT(1), the decapsulator MUST forward the outgoing packet with the ECN field cleared to Not-ECT. The patch takes benefits from common function added in net/inet_ecn.h. Like it was done for Xin4 tunnels, it adds logging to allow detecting broken systems that set ECN bits incorrectly when tunneling (or an intermediate router might be changing the header). Errors are also tracked via rx_frame_error. CC: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: NNicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: NDavid S.
