Geneve can benefit from GRO at the device level in a manner similar to other tunnels, especially as hardware offloads are still emerging. After this patch, aggregated frames are seen on the tunnel interface. Single stream throughput nearly doubles in ideal circumstances (on old hardware). Signed-off-by:

When an error occurs skipping IPv6 extension headers retain the already parsed IP protocol and IPv6 addresses in the flow. Also assume that the packet is not a fragment in the absence of information to the contrary; that is always use the frag_off value set by ipv6_skip_exthdr(). This allows matching on the IP protocol and IPv6 addresses of packets with malformed extension headers. Signed-off-by:

Jiri Benc says: ==================== tunnels: fix incorrect IPv4/v6 headers interpretation With tunneling, it is currently possible to get an IPv6 header and interpret it as an IPv4 header, or to interpret an IPv6 address as an IPv4 address (and vice versa). This leads to things like sending packets to incorrect address, IPv6 flow label being interpreted as IP packet length, etc. Fix several places where this can happen. Most of this is net-next only. The third patch affects net, too, but it doesn't seem there's anything in user space that sets the attribute at all currently, thus net-next is fine. Changelog: v2: fixed geneve after incorrect rebase on top of Pravin's patches ==================== Signed-off-by: -

By default (subject to the sysctl settings), IPv6 sockets listen also for IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in packets received through an IPv6 socket. In addition, it's currently not possible to have both IPv4 and IPv6 vxlan tunnel on the same port (unless bindv6only sysctl is enabled), as it's not possible to create and bind both IPv4 and IPv6 vxlan interfaces and there's no way to specify both IPv4 and IPv6 remote/group IP addresses. Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not done globally in udp_tunnel, as l2tp and tipc seems to work okay when receiving IPv4 packets on IPv6 socket and people may rely on this behavior. The other tunnels (geneve and fou) do not support IPv6. Signed-off-by:

fou does not really support IPv6 encapsulation. After an UDP socket is created in fou_create, the encap_rcv callback is set either to fou_udp_recv or to gue_udp_recv. Both of those unconditionally assume that the received packet has an IPv4 header and access the data at network_header as it was an IPv4 header. This leads to IPv6 flow label being interpreted as IP packet length, etc. Disallow fou tunnel to be configured as IPv6 until real IPv6 support is added to fou.

There's currently nothing preventing directing packets with IPv6 encapsulation data to IPv4 tunnels (and vice versa). If this happens, IPv6 addresses are incorrectly interpreted as IPv4 ones. Track whether the given ip_tunnel_key contains IPv4 or IPv6 data. Store this in ip_tunnel_info. Reject packets at appropriate places if they are supposed to be encapsulated into an incompatible protocol. Signed-off-by:

When removing an non-primary transport during ASCONF processing, we end up traversing the transport list twice: once in sctp_cmd_del_non_primary, and once in sctp_assoc_del_peer.

Since commit c05cdb1b ("netlink: allow large data transfers from user-space"), the kernel may fail to allocate the necessary room for the acknowledgment message back to userspace. This patch introduces a new socket option that trims off the payload of the original netlink message. The netlink message header is still included, so the user can guess from the sequence number what is the message that has triggered the acknowledgment. Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree. In sum, patches to address fallout from the previous round plus updates from the IPVS folks via Simon Horman, they are: 1) Add a new scheduler to IPVS: The weighted overflow scheduling algorithm directs network connections to the server with the highest weight that is currently available and overflows to the next when active connections exceed the node's weight. From Raducu Deaconu. 2) Fix locking ordering in IPVS, always take rtnl_lock in first place. Patch from Julian Anastasov. 3) Allow to indicate the MTU to the IPVS in-kernel state sync daemon. From Julian Anastasov. 4) Enhance multicast configuration for the IPVS state sync daemon. Also from Julian. 5) Resolve sparse warnings in the nf_dup modules. 6) Fix a linking problem when CONFIG_NF_DUP_IPV6 is not set. 7) Add ICMP codes 5 and 6 to IPv6 REJECT target, they are more informative subsets of code 1. From Andreas Herz. 8) Revert the jumpstack size calculation from mark_source_chains due to chain depth miscalculations, from Florian Westphal. 9) Calm down more sparse warning around the Netfilter tree, again from Florian Westphal. ==================== Signed-off-by: -

Previously, the driver would refuse to load if it couldn't secure enough VIs from the MC to fulfill its RSS requirements. This was causing probe to fail on later functions in configurations where we'd run out of VIs, such as having many VFs. This change allows the driver to load with fewer VIs, down to a minimum of 2. A warning will be printed saying that RSS requirements were not met, possibly affecting performance. efx->max_tx_channels needs to be set to avoid going down the failure path in efx_probe_nic() immediately in the loop after the probe() NIC-type function. Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack of VIs. Signed-off-by:
