      These are occuring because the seqcount embedded in u64_stats_sync on

      tcp: reduce the bloat caused by tcp_is_cwnd_limited() · d10473d4
      Eric Dumazet authored
      tcp_is_cwnd_limited() allows GSO/TSO enabled flows to increase
      their cwnd to allow a full size (64KB) TSO packet to be sent.
      
      Non GSO flows only allow an extra room of 3 MSS.
      
      For most flows with a BDP below 10 MSS, this results in a bloat
      of cwnd reaching 90, and an inflate of RTT.
      
      Thanks to TSO auto sizing, we can restrict the bloat to the number
      of MSS contained in a TSO packet (tp->xmit_size_goal_segs), to keep
      original intent without performance impact.
      
      Because we keep cwnd small, it helps to keep TSO packet size to their
      optimal value.
      
      Example for a 10Mbit flow, with low TCP Small queue limits (no more than
      2 skb in qdisc/device tx ring)
      
      Before patch :
      
      lpk51:~# ./ss -i dst lpk52:44862 | grep cwnd
               cubic wscale:6,6 rto:215 rtt:15.875/2.5 mss:1448 cwnd:96
      ssthresh:96
      send 70.1Mbps unacked:14 rcv_space:29200
      
      After patch :
      
      lpk51:~# ./ss -i dst lpk52:52916 | grep cwnd
               cubic wscale:6,6 rto:206 rtt:5.206/0.036 mss:1448 cwnd:15
      ssthresh:14

      ipv6: reuse ip6_frag_id from ip6_ufo_append_data · 916e4cf4
      Hannes Frederic Sowa authored
      Currently we generate a new fragmentation id on UFO segmentation. It
      is pretty hairy to identify the correct net namespace and dst there.
      Especially tunnels use IFF_XMIT_DST_RELEASE and thus have no skb_dst
      available at all.
      
      This causes unreliable or very predictable ipv6 fragmentation id
      generation while segmentation.
      
      Luckily we already have pregenerated the ip6_frag_id in
      ip6_ufo_append_data and can use it here.

      net: sctp: rework multihoming retransmission path selection to rfc4960 · 4c47af4d
      Daniel Borkmann authored
      Problem statement: 1) both paths (primary path1 and alternate
      path2) are up after the association has been established i.e.,
      HB packets are normally exchanged, 2) path2 gets inactive after
      path_max_retrans * max_rto timed out (i.e. path2 is down completely),
      3) now, if a transmission times out on the only surviving/active
      path1 (any ~1sec network service impact could cause this like
      a channel bonding failover), then the retransmitted packets are
      sent over the inactive path2; this happens with partial failover
      and without it.
      
      Besides not being optimal in the above scenario, a small failure
      or timeout in the only existing path has the potential to cause
      long delays in the retransmission (depending on RTO_MAX) until
      the still active path is reselected. Further, when the T3-timeout
      occurs, we have active_patch == retrans_path, and even though the
      timeout occurred on the initial transmission of data, not a
      retransmit, we end up updating retransmit path.
      
      RFC4960, section 6.4. "Multi-Homed SCTP Endpoints" states under
      6.4.1. "Failover from an Inactive Destination Address" the
      following:
      
        Some of the transport addresses of a multi-homed SCTP endpoint
        may become inactive due to either the occurrence of certain
        error conditions (see Section 8.2) or adjustments from the
        SCTP user.
      
        When there is outbound data to send and the primary path
        becomes inactive (e.g., due to failures), or where the SCTP
        user explicitly requests to send data to an inactive
        destination transport address, before reporting an error to
        its ULP, the SCTP endpoint should try to send the data to an
        alternate __active__ destination transport address if one
        exists.
      
        When retransmitting data that timed out, if the endpoint is
        multihomed, it should consider each source-destination address
        pair in its retransmission selection policy. When retransmitting
        timed-out data, the endpoint should attempt to pick the most
        divergent source-destination pair from the original
        source-destination pair to which the packet was transmitted.
      
        Note: Rules for picking the most divergent source-destination
        pair are an implementation decision and are not specified
        within this document.
      
      So, we should first reconsider to take the current active
      retransmission transport if we cannot find an alternative
      active one. If all of that fails, we can still round robin
      through unkown, partial failover, and inactive ones in the
      hope to find something still suitable.
      
      Commit 4141ddc0 ("sctp: retran_path update bug fix") broke
      that behaviour by selecting the next inactive transport when
      no other active transport was found besides the current assoc's
      peer.retran_path. Before commit 4141ddc0, we would have
      traversed through the list until we reach our peer.retran_path
      again, and in case that is still in state SCTP_ACTIVE, we would
      take it and return. Only if that is not the case either, we
      take the next inactive transport.
      
      Besides all that, another issue is that transports in state
      SCTP_UNKNOWN could be preferred over transports in state
      SCTP_ACTIVE in case a SCTP_ACTIVE transport appears after
      SCTP_UNKNOWN in the transport list yielding a weaker transport
      state to be used in retransmission.
      
      This patch mostly reverts 4141ddc0, but also rewrites
      this function to introduce more clarity and strictness into
      the code. A strict priority of transport states is enforced
      in this patch, hence selection is active > unkown > partial
      failover > inactive.
      
      Fixes: 4141ddc0 ("sctp: retran_path update bug fix")

      1) The tcp_sendmsg(...,  @size) argument was ignored.
      
         Code was relying on user not fooling the kernel with iovec mismatches
      
      2) When MTU is about 64KB, tcp_send_syn_data() attempts order-5
      allocations, which are likely to fail when memory gets fragmented.

      In this series, we will fix a regression issue involved by commit
      6e967adf(tipc: relocate common functions from media to bearer)
      But before the issue is fixed, we firstly adjust the process of
      components initialization so as to remove all enabled flags from
      necessary tipc components. Otherwise, without the change, we also
      have to add an extra enabled flag into bearer layer indicating
      whether bearer setup is finshed or not.

      tipc: make bearer set up in module insertion stage · 970122fd
      Ying Xue authored
      Accidentally a side effect is involved by commit 6e967adf(tipc:
      relocate common functions from media to bearer). Now tipc stack
      handler of receiving packets from netdevices as well as netdevice
      notification handler are registered when bearer is enabled rather
      than tipc module initialization stage, but the two handlers are
      both unregistered in tipc module exit phase. If tipc module is
      inserted and then immediately removed, the following warning
      message will appear:
      
      "dev_remove_pack: ffffffffa0380940 not found"
      
      This is because in module insertion stage tipc stack packet handler
      is not registered at all, but in module exit phase dev_remove_pack()
      needs to remove it. Of course, dev_remove_pack() cannot find tipc
      protocol handler from the kernel protocol handler list so that the
      warning message is printed out.
      
      But if registering the two handlers is adjusted from enabling bearer
      phase into inserting module stage, the warning message will be
      eliminated. Due to this change, tipc_core_start_net() and
      tipc_core_stop_net() can be deleted as well.

      tipc: remove all enabled flags from all tipc components · 9fe7ed47
      Ying Xue authored
      When tipc module is inserted, many tipc components are initialized
      one by one. During the initialization period, if one of them is
      failed, tipc_core_stop() will be called to stop all components
      whatever corresponding components are created or not. To avoid to
      release uncreated ones, relevant components have to add necessary
      enabled flags indicating whether they are created or not.
      
      But in the initialization stage, if one component is unsuccessfully
      created, we will just destroy successfully created components before
      the failed component instead of all components. All enabled flags
      defined in components, in turn, become redundant. Additionally it's
      also unnecessary to identify whether table.types is NULL in
      tipc_nametbl_stop() because name stable has been definitely created
      successfully when tipc_nametbl_stop() is called.

      xen-netfront: reset skb network header before checksum · d554f73d
      Wei Liu authored
      In ed1f50c3 ("net: add skb_checksum_setup") we introduced some checksum
      functions in core driver. Subsequent change b5cf66cd ("xen-netfront:
      use new skb_checksum_setup function") made use of those functions to
      replace its own implementation.
      
      However with that change netfront is broken. It sees a lot of checksum
      error. That's because its own implementation of checksum function was a
      bit hacky (dereferencing skb->data directly) while the new function was
      implemented using ip_hdr(). The network header is not reset before skb
      is passed to the new function. When the new function tries to do its
      job, it's confused and reports error.
      
      The fix is simple, we need to reset network header before passing skb to
      checksum function. Netback is not affected as it already does the right
      thing.

      Pull ARM fixes from Russell King:
       "A range of ARM fixes.  Biggest change is the stage-2 attributes used
        for for hyp mode which were wrong.  I've killed some bits in a couple
        of DT files which turned out not to be required, and a few other
        fixes.
      
        One fix touches code outside of arch/arm, which is related to sorting
        out the DMA masks correctly.  There is a long standing issue with the
        conversion from PFNs to addresses where people assume that shifting an
        unsigned long left by PAGE_SHIFT results in a correct address.  This
        is not the case with C: the integer promotion happens at assignment
        after evaluation.  This fixes the recently introduced dma_max_pfn()
        function, but there's a number of other places where we try this
        directly on an unsigned long in the mm code"

      of_mdio: fix phy interrupt passing · f15c586d
      Ben Dooks authored
      The of_mdiobus_register_phy() is not setting phy->irq thus causing
      some drivers to incorrectly assume that the PHY does not have an
      IRQ associated with it. Not only do some drivers report no IRQ
      they do not install an interrupt handler for the PHY.
      
      Simplify the code setting irq and set the phy->irq at the same
      time so that we cover the following issues, which should cover
      all the cases the code will find:
      
      - Set phy->irq if node has irq property and mdio->irq is NULL
      - Set phy->irq if node has no irq and mdio->irq is not NULL
      - Leave phy->irq as PHY_POLL default if none of the above
      
      This fixes the issue:
       net eth0: attached PHY 1 (IRQ -1) to driver Micrel KSZ8041RNLI
      
      to the correct:
       net eth0: attached PHY 1 (IRQ 416) to driver Micrel KSZ8041RNLI

      net: ethernet: update dependency and help text of mvneta · 4b636b53
      Thomas Petazzoni authored
      With the introduction of the support for Armada 375 and Armada 38x,
      the hidden Kconfig option MACH_ARMADA_370_XP is being renamed to
      MACH_MVEBU_V7. Therefore, the dependency that was used for the mvneta
      driver can no longer work. This commit replaces this dependency by a
      dependency on PLAT_ORION, which is used similarly for the mv643xx_eth
      driver.
      
      In addition to this, it takes this opportunity to adjust the
      description and help text to indicate that the driver can is also used
      for Armada 38x. Note that Armada 375 cannot use this driver as it has
      a completely different networking unit, which will require a separate
      driver.

      "As explicitly written in the commit message, we prefer to disable Tx
      AMPDU on NICs supported by iwldvm. This feature gives a big boost in
      Tx performance, but the firmware is buggy and we can't rely on it.
      Our hope is that most of the users out there want wifi to surf on
      the web which means that they care more for Rx traffic than for Tx.
      People who want to enable it can do so with the help of a module
      parameter."

      net: sctp: fix sctp_connectx abi for ia32 emulation/compat mode · ffd59393
      Daniel Borkmann authored
      SCTP's sctp_connectx() abi breaks for 64bit kernels compiled with 32bit
      emulation (e.g. ia32 emulation or x86_x32). Due to internal usage of
      'struct sctp_getaddrs_old' which includes a struct sockaddr pointer,
      sizeof(param) check will always fail in kernel as the structure in
      64bit kernel space is 4bytes larger than for user binaries compiled
      in 32bit mode. Thus, applications making use of sctp_connectx() won't
      be able to run under such circumstances.
      
      Introduce a compat interface in the kernel to deal with such
      situations by using a 'struct compat_sctp_getaddrs_old' structure
      where user data is copied into it, and then sucessively transformed
      into a 'struct sctp_getaddrs_old' structure with the help of
      compat_ptr(). That fixes sctp_connectx() abi without any changes
      needed in user space, and lets the SCTP test suite pass when compiled
      in 32bit and run on 64bit kernels.
