When connected to a QoS/WMM AP, mac80211 should use a QoS NDP for probing it, instead of a regular non-QoS one, fix this. Change all the drivers to *not* allow QoS NDP for now, even though it looks like most of them should be OK with that. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Commit 86dabda4 ("net: thunderbolt: Clear finished Tx frame bus address in tbnet_tx_callback()") fixed a DMA-API violation where the driver called dma_unmap_page() in tbnet_free_buffers() for a bus address that might already be unmapped. The fix was to zero out the bus address of a frame in tbnet_tx_callback(). However, as pointed out by David Miller, zero might well be valid mapping (at least in theory) so it is not good idea to use it here. It turns out that we don't need the whole map/unmap dance for Tx buffers at all. Instead we can map the buffers when they are initially allocated and unmap them when the interface is brought down. In between we just DMA sync the buffers for the CPU or device as needed. Signed-off-by: NMika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Don't offload IP header checksum to NIC. This fixes a previous patch which enabled checksum offloading for both IPv4 and IPv6 packets. So L3 checksum offload was getting enabled for IPv6 pkts.

In the function ipvlan_get_L3_hdr, current codes use pskb_may_pull to make sure the skb header has enough linear room for ipv6 header. But it would use the latter memory directly without linear check when it is icmp. So it still may access the unepxected memory in ipvlan_addr_lookup.

Tuntap and similar devices can inject GSO packets. Accept type VIRTIO_NET_HDR_GSO_UDP, even though not generating UFO natively. Processes are expected to use feature negotiation such as TUNSETOFFLOAD to detect supported offload types and refrain from injecting other packets. This process breaks down with live migration: guest kernels do not renegotiate flags, so destination hosts need to expose all features that the source host does. Partially revert the UFO removal from 182e0b6b~1..d9d30adf. This patch introduces nearly(*) no new code to simplify verification. It brings back verbatim tuntap UFO negotiation, VIRTIO_NET_HDR_GSO_UDP insertion and software UFO segmentation. It does not reinstate protocol stack support, hardware offload (NETIF_F_UFO), SKB_GSO_UDP tunneling in SKB_GSO_SOFTWARE or reception of VIRTIO_NET_HDR_GSO_UDP packets in tuntap. To support SKB_GSO_UDP reappearing in the stack, also reinstate logic in act_csum and openvswitch. Achieve equivalence with v4.13 HEAD by squashing in commit 93991221 ("net: skb_needs_check() removes CHECKSUM_UNNECESSARY check for tx.") and reverting commit 8d63bee6 ("net: avoid skb_warn_bad_offload false positives on UFO"). (*) To avoid having to bring back skb_shinfo(skb)->ip6_frag_id, ipv6_proxy_select_ident is changed to return a __be32 and this is assigned directly to the frag_hdr. Also, SKB_GSO_UDP is inserted at the end of the enum to minimize code churn. Tested Booted a v4.13 guest kernel with QEMU. On a host kernel before this patch `ethtool -k eth0` shows UFO disabled. After the patch, it is enabled, same as on a v4.13 host kernel. A UFO packet sent from the guest appears on the tap device: host: nc -l -p -u 8000 & tcpdump -n -i tap0 guest: dd if=/dev/zero of=payload.txt bs=1 count=2000 nc -u 192.16.1.1 8000 < payload.txt Direct tap to tap transmission of VIRTIO_NET_HDR_GSO_UDP succeeds, packets arriving fragmented: ./with_tap_pair.sh ./tap_send_ufo tap0 tap1 (from https://github.com/wdebruij/kerneltools/tree/master/tests) Changes v1 -> v2 - simplified set_offload change (review comment) - documented test procedure Link: http://lkml.kernel.org/r/<CAF=yD-LuUeDuL9YWPJD9ykOZ0QCjNeznPDr6whqZ9NGMNF12Mw@mail.gmail.com> Fixes: fb652fdf ("macvlan/macvtap: Remove NETIF_F_UFO advertisement.")

This patch fixes an issue seen on Power systems with ixgbe which results in skb list corruption and an eventual kernel oops. The following is what was observed: CPU 1 CPU2 ============================ ============================ 1: ixgbe_xmit_frame_ring ixgbe_clean_tx_irq 2: first->skb = skb eop_desc = tx_buffer->next_to_watch 3: ixgbe_tx_map read_barrier_depends() 4: wmb check adapter written status bit 5: first->next_to_watch = tx_desc napi_consume_skb(tx_buffer->skb ..); 6: writel(i, tx_ring->tail); The read_barrier_depends is insufficient to ensure that tx_buffer->skb does not get loaded prior to tx_buffer->next_to_watch, which then results in loading a stale skb pointer. This patch replaces the read_barrier_depends with smp_rmb to ensure loads are ordered with respect to the load of tx_buffer->next_to_watch.

The current method for notifying clients of l2 parameters is broken because we fail to copy the new parameters to the client instance struct, we need to do the notification before the client 'open' function pointer gets called, and lastly we should set the l2 parameters when first adding a client instance. This patch first introduces the i40evf_client_get_params function to prevent code duplication in the i40evf_client_add_instance and the i40evf_notify_client_l2_params functions. We then fix the notify l2 params function to actually copy the parameters to client instance struct and do the same in the *_add_instance' function. Lastly this patch reorganizes the priority in which client tasks fire so that if the flag for notifying l2 params is set, it will trigger before the open because the client needs these new parameters as part of a client open task.

Since commit 96a39aed ("i40e: Acquire NVM lock before reads on all devices") we've used the NVM lock to synchronize NVM reads even on devices which don't strictly need the lock. Doing so can cause a regression on older firmware prior to 1.5, especially when downgrading the firmware. Fix this by only grabbing the lock if we're running on an X722 device (which requires the lock as it uses the AdminQ to read the NVM), or if we're currently running 1.5 or newer firmware.

With TC shared block changes we can't depend on correct netdev pointer being available in cls_bpf. Move the device validation to the driver. Core will only make sure that offloaded programs are always attached in the driver (or in HW by the driver). We trust that drivers which implement offload callbacks will perform necessary checks. Moving the checks to the driver is generally a useful thing, in practice the check should be against a switchdev instance, not a netdev, given that most ASICs will probably allow using the same program on many ports.
