      dt-bindings: net: meson-dwmac: new compatible name for AXG SoC · 7e5d05e1
      Yixun Lan authored
      We need to introduce a new compatible name for the Meson-AXG SoC
      in order to support the RMII 100M ethernet PHY, since the PRG_ETH0
      register of the dwmac glue layer is changed from previous old SoC.

      ====================
      netns: uevent filtering
      
      This is the new approach to uevent filtering as discussed (see the
      threads in [1], [2], and [3]). It only contains *non-functional
      changes*.
      
      This series deals with with fixing up uevent filtering logic:
      - uevent filtering logic is simplified
      - locking time on uevent_sock_list is minimized
      - tagged and untagged kobjects are handled in separate codepaths
      - permissions for userspace are fixed for network device uevents in
        network namespaces owned by non-initial user namespaces
        Udev is now able to see those events correctly which it wasn't before.
        For example, moving a physical device into a network namespace not
        owned by the initial user namespaces before gave:
      
        root@xen1:~# udevadm --debug monitor -k
        calling: monitor
        monitor will print the received events for:
        KERNEL - the kernel uevent
      
        sender uid=65534, message ignored
        sender uid=65534, message ignored
        sender uid=65534, message ignored
        sender uid=65534, message ignored
        sender uid=65534, message ignored
      
        and now after the discussion and solution in [3] correctly gives:
      
        root@xen1:~# udevadm --debug monitor -k
        calling: monitor
        monitor will print the received events for:
        KERNEL - the kernel uevent
      
        KERNEL[625.301042] add      /devices/pci0000:00/0000:00:02.0/0000:01:00.1/net/enp1s0f1 (net)
        KERNEL[625.301109] move     /devices/pci0000:00/0000:00:02.0/0000:01:00.1/net/enp1s0f1 (net)
        KERNEL[625.301138] move     /devices/pci0000:00/0000:00:02.0/0000:01:00.1/net/eth1 (net)

      netns: restrict uevents · a3498436
      Christian Brauner authored
      commit 07e98962 ("kobject: Send hotplug events in all network namespaces")
      
      enabled sending hotplug events into all network namespaces back in 2010.
      Over time the set of uevents that get sent into all network namespaces has
      shrunk. We have now reached the point where hotplug events for all devices
      that carry a namespace tag are filtered according to that namespace.
      Specifically, they are filtered whenever the namespace tag of the kobject
      does not match the namespace tag of the netlink socket.
      Currently, only network devices carry namespace tags (i.e. network
      namespace tags). Hence, uevents for network devices only show up in the
      network namespace such devices are created in or moved to.
      
      However, any uevent for a kobject that does not have a namespace tag
      associated with it will not be filtered and we will broadcast it into all
      network namespaces. This behavior stopped making sense when user namespaces
      were introduced.
      
      This patch simplifies and fixes couple of things:
      - Split codepath for sending uevents by kobject namespace tags:
        1. Untagged kobjects - uevent_net_broadcast_untagged():
           Untagged kobjects will be broadcast into all uevent sockets recorded
           in uevent_sock_list, i.e. into all network namespacs owned by the
           intial user namespace.
        2. Tagged kobjects - uevent_net_broadcast_tagged():
           Tagged kobjects will only be broadcast into the network namespace they
           were tagged with.
        Handling of tagged kobjects in 2. does not cause any semantic changes.
        This is just splitting out the filtering logic that was handled by
        kobj_bcast_filter() before.
        Handling of untagged kobjects in 1. will cause a semantic change. The
        reasons why this is needed and ok have been discussed in [1]. Here is a
        short summary:
        - Userspace ignores uevents from network namespaces that are not owned by
          the intial user namespace:
          Uevents are filtered by userspace in a user namespace because the
          received uid != 0. Instead the uid associated with the event will be
          65534 == "nobody" because the global root uid is not mapped.
          This means we can safely and without introducing regressions modify the
          kernel to not send uevents into all network namespaces whose owning
          user namespace is not the initial user namespace because we know that
          userspace will ignore the message because of the uid anyway.
          I have a) verified that is is true for every udev implementation out
          there b) that this behavior has been present in all udev
          implementations from the very beginning.
        - Thundering herd:
          Broadcasting uevents into all network namespaces introduces significant
          overhead.
          All processes that listen to uevents running in non-initial user
          namespaces will end up responding to uevents that will be meaningless
          to them. Mainly, because non-initial user namespaces cannot easily
          manage devices unless they have a privileged host-process helping them
          out. This means that there will be a thundering herd of activity when
          there shouldn't be any.
        - Removing needless overhead/Increasing performance:
          Currently, the uevent socket for each network namespace is added to the
          global variable uevent_sock_list. The list itself needs to be protected
          by a mutex. So everytime a uevent is generated the mutex is taken on
          the list. The mutex is held *from the creation of the uevent (memory
          allocation, string creation etc. until all uevent sockets have been
          handled*. This is aggravated by the fact that for each uevent socket
          that has listeners the mc_list must be walked as well which means we're
          talking O(n^2) here. Given that a standard Linux workload usually has
          quite a lot of network namespaces and - in the face of containers - a
          lot of user namespaces this quickly becomes a performance problem (see
          "Thundering herd" above). By just recording uevent sockets of network
          namespaces that are owned by the initial user namespace we
          significantly increase performance in this codepath.
        - Injecting uevents:
          There's a valid argument that containers might be interested in
          receiving device events especially if they are delegated to them by a
          privileged userspace process. One prime example are SR-IOV enabled
          devices that are explicitly designed to be handed of to other users
          such as VMs or containers.
          This use-case can now be correctly handled since
          commit 692ec06d ("netns: send uevent messages"). This commit
          introduced the ability to send uevents from userspace. As such we can
          let a sufficiently privileged (CAP_SYS_ADMIN in the owning user
          namespace of the network namespace of the netlink socket) userspace
          process make a decision what uevents should be sent. This removes the
          need to blindly broadcast uevents into all user namespaces and provides
          a performant and safe solution to this problem.
        - Filtering logic:
          This patch filters by *owning user namespace of the network namespace a
          given task resides in* and not by user namespace of the task per se.
          This means if the user namespace of a given task is unshared but the
          network namespace is kept and is owned by the initial user namespace a
          listener that is opening the uevent socket in that network namespace
          can still listen to uevents.
      - Fix permission for tagged kobjects:
        Network devices that are created or moved into a network namespace that
        is owned by a non-initial user namespace currently are send with
        INVALID_{G,U}ID in their credentials. This means that all current udev
        implementations in userspace will ignore the uevent they receive for
        them. This has lead to weird bugs whereby new devices showing up in such
        network namespaces were not recognized and did not get IPs assigned etc.
        This patch adjusts the permission to the appropriate {g,u}id in the
        respective user namespace. This way udevd is able to correctly handle
        such devices.
      - Simplify filtering logic:
        do_one_broadcast() already ensures that only listeners in mc_list receive
        uevents that have the same network namespace as the uevent socket itself.
        So the filtering logic in kobj_bcast_filter is not needed (see [3]). This
        patch therefore removes kobj_bcast_filter() and replaces
        netlink_broadcast_filtered() with the simpler netlink_broadcast()
        everywhere.

      This series adds a generic infrastructure to offload TLS crypto to a
      network devices. It enables the kernel TLS socket to skip encryption and
      authentication operations on the transmit side of the data path. Leaving
      those computationally expensive operations to the NIC.
      
      The NIC offload infrastructure builds TLS records and pushes them to the
      TCP layer just like the SW KTLS implementation and using the same API.
      TCP segmentation is mostly unaffected. Currently the only exception is
      that we prevent mixed SKBs where only part of the payload requires
      offload. In the future we are likely to add a similar restriction
      following a change cipher spec record.
      
      The notable differences between SW KTLS and NIC offloaded TLS
      implementations are as follows:
      1. The offloaded implementation builds "plaintext TLS record", those
      records contain plaintext instead of ciphertext and place holder bytes
      instead of authentication tags.
      2. The offloaded implementation maintains a mapping from TCP sequence
      number to TLS records. Thus given a TCP SKB sent from a NIC offloaded
      TLS socket, we can use the tls NIC offload infrastructure to obtain
      enough context to encrypt the payload of the SKB.
      A TLS record is released when the last byte of the record is ack'ed,
      this is done through the new icsk_clean_acked callback.
      
      The infrastructure should be extendable to support various NIC offload
      implementations.  However it is currently written with the
      implementation below in mind:
      The NIC assumes that packets from each offloaded stream are sent as
      plaintext and in-order. It keeps track of the TLS records in the TCP
      stream. When a packet marked for offload is transmitted, the NIC
      encrypts the payload in-place and puts authentication tags in the
      relevant place holders.
      
      The responsibility for handling out-of-order packets (i.e. TCP
      retransmission, qdisc drops) falls on the netdev driver.
      
      The netdev driver keeps track of the expected TCP SN from the NIC's
      perspective.  If the next packet to transmit matches the expected TCP
      SN, the driver advances the expected TCP SN, and transmits the packet
      with TLS offload indication.
      
      If the next packet to transmit does not match the expected TCP SN. The
      driver calls the TLS layer to obtain the TLS record that includes the
      TCP of the packet for transmission. Using this TLS record, the driver
      posts a work entry on the transmit queue to reconstruct the NIC TLS
      state required for the offload of the out-of-order packet. It updates
      the expected TCP SN accordingly and transmit the now in-order packet.
      The same queue is used for packet transmission and TLS context
      reconstruction to avoid the need for flushing the transmit queue before
      issuing the context reconstruction request.
      
      Expected TCP SN is accessed without a lock, under the assumption that
      TCP doesn't transmit SKBs from different TX queue concurrently.
      
      If packets are rerouted to a different netdevice, then a software
      fallback routine handles encryption.

      TCP of the packet for transmission. Using this TLS record, the driver
      posts a work entry on the transmit queue to reconstruct the NIC TLS
      state required for the offload of the out-of-order packet. It updates
      the expected TCP SN accordingly and transmits the now in-order packet.
      The same queue is used for packet transmission and TLS context
      reconstruction to avoid the need for flushing the transmit queue before
      issuing the context reconstruction request.

      net/tls: Split conf to rx + tx · f66de3ee
      Boris Pismenny authored
      In TLS inline crypto, we can have one direction in software
      and another in hardware. Thus, we split the TLS configuration to separate
      structures for receive and transmit.

      net: Add Software fallback infrastructure for socket dependent offloads · ebf4e808
      Ilya Lesokhin authored
      With socket dependent offloads we rely on the netdev to transform
      the transmitted packets before sending them to the wire.
      When a packet from an offloaded socket is rerouted to a different
      device we need to detect it and do the transformation in software.

      net: Rename and export copy_skb_header · 08303c18
      Ilya Lesokhin authored
      copy_skb_header is renamed to skb_copy_header and
      exported. Exposing this function give more flexibility
      in copying SKBs.
      skb_copy and skb_copy_expand do not give enough control
      over which parts are copied.

      ====================
      40GbE Intel Wired LAN Driver Updates 2018-04-30
      
      This series contains updates to i40e and i40evf only.
      
      Jia-Ju Bai replaces an instance of GFP_ATOMIC to GFP_KERNEL, since
      i40evf is not in atomic context when i40evf_add_vlan() is called.
      
      Jake cleans up function header comments to ensure that the function
      parameter comments actually match the function parameters.  Fixed a
      possible overflow error in the PTP clock code.  Fixed warnings regarding
      restricted __be32 type usage.
      
      Mariusz fixes the reading of the LLDP configuration, which moves from
      using relative values to calculating the absolute address.
      
      Jakub adds a check for 10G LR mode for i40e.
      
      Paweł fixes an issue, where changing the MTU would turn on TSO, GSO and
      GRO.
      
      Alex fixes a couple of issues with the UDP tunnel filter configuration.
      First being that the tunnels did not have mutual exclusion in place to
      prevent a race condition between a user request to add/remove a port and
      an update.  The second issue was we were deleting filters that were not
      associated with the actual filter we wanted to delete.
      
      Harshitha ensures that the queue map sent by the VF is taken into
      account when enabling/disabling queues in the VF VSI.
