udp6_sock_seq_show and raw6_sock_seq_show are identical, except the UDP version displays ports and the raw version displays the protocol. Refactor most of the code in these two functions into a new common ip6_dgram_sock_seq_show function, in preparation for using it to display ICMPv6 sockets as well. Also reduce the indentation in parts of include/net/transp_v6.h to improve readability. Compiles and displays reasonable results with CONFIG_IPV6={n,m,y} Signed-off-by: NLorenzo Colitti <lorenzo@google.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds the support of IPv4 over Ipv4 for the module sit. The gain of this feature is to be able to have 4in4 and 6in4 over the same interface instead of having one interface for 6in4 and another for 4in4 even if encapsulation addresses are the same. To avoid conflicting with ipip module, sit IPv4 over IPv4 protocol is registered with a smaller priority. Signed-off-by: NNicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: NDavid S.

This corrects an regression introduced by "net: Use 16bits for *_headers fields of struct skbuff" when NET_SKBUFF_DATA_USES_OFFSET is not set. In that case skb->tail will be a pointer whereas skb->transport_header will be an offset from head. This is corrected by using wrappers that ensure that comparisons and calculations are always made using pointers. Signed-off-by: NSimon Horman <horms@verge.net.au> Signed-off-by: NDavid S.

In the case where a non-MPLS packet is received and an MPLS stack is added it may well be the case that the original skb is GSO but the NIC used for transmit does not support GSO of MPLS packets. The aim of this code is to provide GSO in software for MPLS packets whose skbs are GSO. SKB Usage: When an implementation adds an MPLS stack to a non-MPLS packet it should do the following to skb metadata: * Set skb->inner_protocol to the old non-MPLS ethertype of the packet. skb->inner_protocol is added by this patch. * Set skb->protocol to the new MPLS ethertype of the packet. * Set skb->network_header to correspond to the end of the L3 header, including the MPLS label stack. I have posted a patch, "[PATCH v3.29] datapath: Add basic MPLS support to kernel" which adds MPLS support to the kernel datapath of Open vSwtich. That patch sets the above requirements in datapath/actions.c:push_mpls() and was used to exercise this code. The datapath patch is against the Open vSwtich tree but it is intended that it be added to the Open vSwtich code present in the mainline Linux kernel at some point. Features: I believe that the approach that I have taken is at least partially consistent with the handling of other protocols. Jesse, I understand that you have some ideas here. I am more than happy to change my implementation. This patch adds dev->mpls_features which may be used by devices to advertise features supported for MPLS packets. A new NETIF_F_MPLS_GSO feature is added for devices which support hardware MPLS GSO offload. Currently no devices support this and MPLS GSO always falls back to software. Alternate Implementation: One possible alternate implementation is to teach netif_skb_features() and skb_network_protocol() about MPLS, in a similar way to their understanding of VLANs. I believe this would avoid the need for net/mpls/mpls_gso.c and in particular the calls to __skb_push() and __skb_push() in mpls_gso_segment(). I have decided on the implementation in this patch as it should not introduce any overhead in the case where mpls_gso is not compiled into the kernel or inserted as a module. MPLS GSO suggested by Jesse Gross. Based in part on "v4 GRE: Add TCP segmentation offload for GRE" by Pravin B Shelar.

This adds the ability to send ICMPv6 echo requests without a raw socket. The equivalent ability for ICMPv4 was added in 2011. Instead of having separate code paths for IPv4 and IPv6, make most of the code in net/ipv4/ping.c dual-stack and only add a few IPv6-specific bits (like the protocol definition) to a new net/ipv6/ping.c. Hopefully this will reduce divergence and/or duplication of bugs in the future. Caveats: - Setting options via ancillary data (e.g., using IPV6_PKTINFO to specify the outgoing interface) is not yet supported. - There are no separate security settings for IPv4 and IPv6; everything is controlled by /proc/net/ipv4/ping_group_range. - The proc interface does not yet display IPv6 ping sockets properly. Tested with a patched copy of ping6 and using raw socket calls. Compiles and works with all of CONFIG_IPV6={n,m,y}. Signed-off-by: NLorenzo Colitti <lorenzo@google.com> Signed-off-by: NDavid S.

This patch adds the support of peer address for IPv6. For example, it is possible to specify the remote end of a 6inY tunnel. This was already possible in IPv4: ip addr add ip1 peer ip2 dev dev1 The peer address is specified with IFA_ADDRESS and the local address with IFA_LOCAL (like explained in include/uapi/linux/if_addr.h). Note that the API is not changed, because before this patch, it was not possible to specify two different addresses in IFA_LOCAL and IFA_REMOTE. There is a small change for the dump: if the peer is different from ::, IFA_ADDRESS will contain the peer address instead of the local address.

This patch extends logic used in commit fcbdf09d ("net: fix nulls list corruptions in sk_prot_alloc") TCP/UDP/UDPLite IPv6 protocols provide their own .clear_sk() method to make sure we do not clear pinet6 field.

Commit 4a94445c (net: Use ip_route_input_noref() in input path) added a bug in IP defragmentation handling, as non refcounted dst could escape an RCU protected section. Commit 64f3b9e2 (net: ip_expire() must revalidate route) fixed the case of timeouts, but not the general problem. Tom Parkin noticed crashes in UDP stack and provided a patch, but further analysis permitted us to pinpoint the root cause. Before queueing a packet into a frag list, we must drop its dst, as this dst has limited lifetime (RCU protected) When/if a packet is finally reassembled, we use the dst of the very last skb, still protected by RCU and valid, as the dst of the reassembled packet. Use same logic in IPv6, as there is no need to hold dst references.

Instead of invalidating all IPv6 addresses with global scope when one decides to use IPv6 tokens, we should only invalidate previous tokens and leave the rest intact until they expire eventually (or are intact forever). For doing this less greedy approach, we're adding a bool at the end of inet6_ifaddr structure instead, for two reasons: i) per-inet6_ifaddr flag space is already used up, making it wider might not be a good idea, since ii) also we do not necessarily need to export this information into user space.

This patch adds support for IPv6 tokenized IIDs, that allow for administrators to assign well-known host-part addresses to nodes whilst still obtaining global network prefix from Router Advertisements. It is currently in draft status. The primary target for such support is server platforms where addresses are usually manually configured, rather than using DHCPv6 or SLAAC. By using tokenised identifiers, hosts can still determine their network prefix by use of SLAAC, but more readily be automatically renumbered should their network prefix change. [...] The disadvantage with static addresses is that they are likely to require manual editing should the network prefix in use change. If instead there were a method to only manually configure the static identifier part of the IPv6 address, then the address could be automatically updated when a new prefix was introduced, as described in [RFC4192] for example. In such cases a DNS server might be configured with such a tokenised interface identifier of ::53, and SLAAC would use the token in constructing the interface address, using the advertised prefix. [...] http://tools.ietf.org/html/draft-chown-6man-tokenised-ipv6-identifiers-02 The implementation is partially based on top of Mark K. Thompson's proof of concept. However, it uses the Netlink interface for configuration resp. data retrival, so that it can be easily extended in future. Successfully tested by myself.

Tetja Rediske found that if the host receives an ICMPv6 redirect message after sending a SYN+ACK, the connection will be reset. He bisected it down to 093d04d4 (ipv6: Change skb->data before using icmpv6_notify() to propagate redirect), but the origin of the bug comes from ec18d9a2 (ipv6: Add redirect support to all protocol icmp error handlers.). The bug simply did not trigger prior to 093d04d4, because skb->data did not point to the inner IP header and thus icmpv6_notify did not call the correct err_handler. This patch adds the missing "goto out;" in tcp_v6_err. After receiving an ICMPv6 Redirect, we should not continue processing the ICMP in tcp_v6_err, as this may trigger the removal of request-socks or setting sk_err(_soft).

This patch adds netns support to nf_log and it prepares netns support for existing loggers. It is composed of four major changes. 1) nf_log_register has been split to two functions: nf_log_register and nf_log_set. The new nf_log_register is used to globally register the nf_logger and nf_log_set is used for enabling pernet support from nf_loggers. Per netns is not yet complete after this patch, it comes in separate follow up patches. 2) Add net as a parameter of nf_log_bind_pf. Per netns is not yet complete after this patch, it only allows to bind the nf_logger to the protocol family from init_net and it skips other cases. 3) Adapt all nf_log_packet callers to pass netns as parameter. After this patch, this function only works for init_net. 4) Make the sysctl net/netfilter/nf_log pernet.

IPv6 Routing table becomes broken once we do ifdown, ifup of the loopback(lo) interface. After down-up, routes of other interface's IPv6 addresses through 'lo' are lost. IPv6 addresses assigned to all interfaces are routed through 'lo' for internal communication. Once 'lo' is down, those routing entries are removed from routing table. But those removed entries are not being re-created properly when 'lo' is brought up. So IPv6 addresses of other interfaces becomes unreachable from the same machine. Also this breaks communication with other machines because of NDISC packet processing failure. This patch fixes this issue by reading all interface's IPv6 addresses and adding them to IPv6 routing table while bringing up 'lo'. ==Testing== Before applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ After applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ Signed-off-by: NBalakumaran Kannan <Balakumaran.Kannan@ap.sony.com> Signed-off-by: NMaruthi Thotad <Maruthi.Thotad@ap.sony.com> Signed-off-by: NDavid S.

Erik Hugne's errata proposal (Errata ID: 3480) to RFC4291 has been verified: http://www.rfc-editor.org/errata_search.php?eid=3480 We have to check for pkt_type and loopback flag because either the packets are allowed to travel over the loopback interface (in which case pkt_type is PACKET_HOST and IFF_LOOPBACK flag is set) or they travel over a non-loopback interface back to us (in which case PACKET_TYPE is PACKET_LOOPBACK and IFF_LOOPBACK flag is not set).

Following patch refactors GRE code into ip tunneling code and GRE specific code. Common tunneling code is moved to ip_tunnel module. ip_tunnel module is written as generic library which can be used by different tunneling implementations. ip_tunnel module contains following components: - packet xmit and rcv generic code. xmit flow looks like (gre_xmit/ipip_xmit)->ip_tunnel_xmit->ip_local_out. - hash table of all devices. - lookup for tunnel devices. - control plane operations like device create, destroy, ioctl, netlink operations code. - registration for tunneling modules, like gre, ipip etc. - define single pcpu_tstats dev->tstats. - struct tnl_ptk_info added to pass parsed tunnel packet parameters. ipip.h header is renamed to ip_tunnel.h Signed-off-by: NPravin B Shelar <pshelar@nicira.com> Signed-off-by: NDavid S.
