      Jiri Pirko authored
      Similar to what is implemented in bonding. User is able to ask team
      driver to send IGMP rejoins in case port is enabled or disabled. Using
      previously introduced netdev notifier.

      net: convert resend IGMP to notifier event · 4aa5dee4
      Jiri Pirko authored
      Until now, bond_resend_igmp_join_requests() looks for vlans attached to
      bonding device, bridge where bonding act as port manually. It does not
      care of other scenarios, like stacked bonds or team device above. Make
      this more generic and use netdev notifier to propagate the event to
      upper devices and to actually call ip_mc_rejoin_groups().

      vxlan fdb replace an existing entry · 906dc186
      Thomas Richter authored
      Add support to replace an existing entry found in the
      vxlan fdb database. The entry in question is identified
      by its unicast mac address and the destination information
      is changed. If the entry is not found, it is added in the
      forwarding database. This is similar to changing an entry
      in the neighbour table.
      
      Multicast mac addresses can not be changed with the replace
      option.
      
      This is useful for virtual machine migration when the
      destination of a target virtual machine changes. The replace
      feature can be used instead of delete followed by add.

      tcp: use RTT from SACK for RTO · ed08495c
      Yuchung Cheng authored
      If RTT is not available because Karn's check has failed or no
      new packet is acked, use the RTT measured from SACK to estimate
      the RTO. The sender can continue to estimate the RTO during loss
      recovery or reordering event upon receiving non-partial ACKs.
      
      This also changes when the RTO is re-armed. Previously it is
      only re-armed when some data is cummulatively acknowledged (i.e.,
      SND.UNA advances), but now it is re-armed whenever RTT estimator
      is updated. This feature is particularly useful to reduce spurious
      timeout for buffer bloat including cellular carriers [1], and
      RTT estimation on reordering events.

      tcp: measure RTT from new SACK · 59c9af42
      Yuchung Cheng authored
      Take RTT sample if an ACK selectively acks some sequences that
      have never been retransmitted. The Karn's algorithm does not apply
      even if that ACK (s)acks other retransmitted sequences, because it
      must been generated by an original but perhaps out-of-order packet.
      There is no ambiguity. In case when multiple blocks are newly
      sacked because of ACK losses the earliest block is used to
      measure RTT, similar to cummulative ACKs.
      
      Such RTT samples allow the sender to estimate the RTO during loss
      recovery and packet reordering events. It is still useful even with
      TCP timestamps. That's because during these events the SND.UNA may
      not advance preventing RTT samples from TS ECR (thus the FLAG_ACKED
      check before calling tcp_ack_update_rtt()).  Therefore this new
      RTT source is complementary to existing ACK and TS RTT mechanisms.
      
      This patch does not update the RTO. It is done in the next patch.

      tcp: prefer packet timing to TS-ECR for RTT · 5b08e47c
      Yuchung Cheng authored
      Prefer packet timings to TS-ecr for RTT measurements when both
      sources are available. That's because broken middle-boxes and remote
      peer can return packets with corrupted TS ECR fields. Similarly most
      congestion controls that require RTT signals favor timing-based
      sources as well. Also check for bad TS ECR values to avoid RTT
      blow-ups. It has happened on production Web servers.

      tcp: consolidate SYNACK RTT sampling · 375fe02c
      Yuchung Cheng authored
      The first patch consolidates SYNACK and other RTT measurement to use a
      central function tcp_ack_update_rtt(). A (small) bonus is now SYNACK
      RTT measurement happens after PAWS check, potentially reducing the
      impact of RTO seeding on bad TCP timestamps values.

       "A couple interesting SKB fragment handling fixes, plus the usual small
        bits here and there:
      
         1) Fix 64-bit divide build failure on 32-bit platforms in mlx5, from
            Tim Gardner.
      
         2) Get rid of a stupid reimplementation on "%*phC" in our sysfs MAC
            address printing helper.
      
         3) Fix NETIF_F_SG capability advertisement in hyperv driver, if the
            device can't do checksumming offloads then it shouldn't say it can
            do SG either.  From Haiyang Zhang.
      
         4) bgmac needs to depend on PHYLIB, from Hauke Mehrtens.
      
         5) Don't leak DMA mappings on mapping failures, from Neil Horman.
      
         6) We need to reset the transport header of SKBs in ipv4 before we
            attempt to perform early socket demux, just like ipv6 does.  From
            Eric Dumazet.
      
         7) Add missing locking on vxlan device removal, from Stephen
            Hemminger.
      
         8) xen-netfront has to make two passes over an SKB to prepare it for
            transfer.  One pass calculates the number of slots needed, the
            second massages the SKB and fills the slots.  Unfortunately, the
            first pass doesn't calculate the number of slots properly so we
            can end up trying to build a MAX_SKB_FRAGS + 1 SKB which doesn't
            work out so well.  Fix from Jan Beulich with help and discussion
            with several others.
      
         9) Fix a similar problem in tun and macvtap, which have to split up
            scatter-gather elements at PAGE_SIZE boundaries.  Don't do
            zerocopy if it would result in a > MAX_SKB_FRAGS skb.  Fixes from
            Jason Wang.
      
        10) On receive, once we've decoded the VLAN state completely, clear
            skb->vlan_tci.  Otherwise demuxed tunnels underneath can trigger
            the VLAN code again, corrupting the packet.  Fix from Eric
            Dumazet"

      vlan: mask vlan prio bits · d4b812de
      Eric Dumazet authored
      In commit 48cc32d3
      ("vlan: don't deliver frames for unknown vlans to protocols")
      Florian made sure we set pkt_type to PACKET_OTHERHOST
      if the vlan id is set and we could find a vlan device for this
      particular id.
      
      But we also have a problem if prio bits are set.
      
      Steinar reported an issue on a router receiving IPv6 frames with a
      vlan tag of 4000 (id 0, prio 2), and tunneled into a sit device,
      because skb->vlan_tci is set.
      
      Forwarded frame is completely corrupted : We can see (8100:4000)
      being inserted in the middle of IPv6 source address :

      It seems we are not really ready to properly cope with this right now.
      
      We can probably do better in future kernels :
      vlan_get_ingress_priority() should be a netdev property instead of
      a per vlan_dev one.
      
      For stable kernels, lets clear vlan_tci to fix the bugs.

      macvtap: do not zerocopy if iov needs more pages than MAX_SKB_FRAGS · ece793fc
      Jason Wang authored
      We try to linearize part of the skb when the number of iov is greater than
      MAX_SKB_FRAGS. This is not enough since each single vector may occupy more than
      one pages, so zerocopy_sg_fromiovec() may still fail and may break the guest
      network.
      
      Solve this problem by calculate the pages needed for iov before trying to do
      zerocopy and switch to use copy instead of zerocopy if it needs more than
      MAX_SKB_FRAGS.
      
      This is done through introducing a new helper to count the pages for iov, and
      call uarg->callback() manually when switching from zerocopy to copy to notify
      vhost.
      
      We can do further optimization on top.

      pkt_sched: sch_qfq: remove a source of high packet delay/jitter · 87f40dd6
      Paolo Valente authored
      QFQ+ inherits from QFQ a design choice that may cause a high packet
      delay/jitter and a severe short-term unfairness. As QFQ, QFQ+ uses a
      special quantity, the system virtual time, to track the service
      provided by the ideal system it approximates. When a packet is
      dequeued, this quantity must be incremented by the size of the packet,
      divided by the sum of the weights of the aggregates waiting to be
      served. Tracking this sum correctly is a non-trivial task, because, to
      preserve tight service guarantees, the decrement of this sum must be
      delayed in a special way [1]: this sum can be decremented only after
      that its value would decrease also in the ideal system approximated by
      QFQ+. For efficiency, QFQ+ keeps track only of the 'instantaneous'
      weight sum, increased and decreased immediately as the weight of an
      aggregate changes, and as an aggregate is created or destroyed (which,
      in its turn, happens as a consequence of some class being
      created/destroyed/changed). However, to avoid the problems caused to
      service guarantees by these immediate decreases, QFQ+ increments the
      system virtual time using the maximum value allowed for the weight
      sum, 2^10, in place of the dynamic, instantaneous value. The
      instantaneous value of the weight sum is used only to check whether a
      request of weight increase or a class creation can be satisfied.
      
      Unfortunately, the problems caused by this choice are worse than the
      temporary degradation of the service guarantees that may occur, when a
      class is changed or destroyed, if the instantaneous value of the
      weight sum was used to update the system virtual time. In fact, the
      fraction of the link bandwidth guaranteed by QFQ+ to each aggregate is
      equal to the ratio between the weight of the aggregate and the sum of
      the weights of the competing aggregates. The packet delay guaranteed
      to the aggregate is instead inversely proportional to the guaranteed
      bandwidth. By using the maximum possible value, and not the actual
      value of the weight sum, QFQ+ provides each aggregate with the worst
      possible service guarantees, and not with service guarantees related
      to the actual set of competing aggregates. To see the consequences of
      this fact, consider the following simple example.
      
      Suppose that only the following aggregates are backlogged, i.e., that
      only the classes in the following aggregates have packets to transmit:
      one aggregate with weight 10, say A, and ten aggregates with weight 1,
      say B1, B2, ..., B10. In particular, suppose that these aggregates are
      always backlogged. Given the weight distribution, the smoothest and
      fairest service order would be:
      A B1 A B2 A B3 A B4 A B5 A B6 A B7 A B8 A B9 A B10 A B1 A B2 ...
      
      QFQ+ would provide exactly this optimal service if it used the actual
      value for the weight sum instead of the maximum possible value, i.e.,
      11 instead of 2^10. In contrast, since QFQ+ uses the latter value, it
      serves aggregates as follows (easy to prove and to reproduce
      experimentally):
      A B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 A A A A A A A A A A B1 B2 ... B10 A A ...
      
      By replacing 10 with N in the above example, and by increasing N, one
      can increase at will the maximum packet delay and the jitter
      experienced by the classes in aggregate A.
      
      This patch addresses this issue by just using the above
      'instantaneous' value of the weight sum, instead of the maximum
      possible value, when updating the system virtual time.  After the
      instantaneous weight sum is decreased, QFQ+ may deviate from the ideal
      service for a time interval in the order of the time to serve one
      maximum-size packet for each backlogged class. The worst-case extent
      of the deviation exhibited by QFQ+ during this time interval [1] is
      basically the same as of the deviation described above (but, without
      this patch, QFQ+ suffers from such a deviation all the time). Finally,
      this patch modifies the comment to the function qfq_slot_insert, to
      make it coherent with the fact that the weight sum used by QFQ+ can
      now be lower than the maximum possible value.

      Pull driver core patches from Greg KH:
       "Here are some driver core patches for 3.11-rc2.  They aren't really
        bugfixes, but a bunch of new helper macros for drivers to properly
        create attribute groups, which drivers and subsystems need to fix up a
        ton of race issues with incorrectly creating sysfs files (binary and
        normal) after userspace has been told that the device is present.
      
        Also here is the ability to create binary files as attribute groups,
        to solve that race condition, which was impossible to do before this,
        so that's my fault the drivers were broken.
      
        The majority of the .c changes is indenting and moving code around a
        bit.  It affects no existing code, but allows the large backlog of 70+
        patches that I already have created to start flowing into the
        different subtrees, instead of having to live in my driver-core tree,
        causing merge nightmares in linux-next for the next few months.
      
        These were finalized too late for the -rc1 merge window, which is why
        they were didn't make that pull request, testing and review from
        others didn't happen until a few weeks ago, and then there's the whole
        distraction of the past few days, which prevented these from getting
        to you sooner, sorry about that.
      
        Oh, and there's a bugfix for the documentation build warning in here
        as well.  All of these have been in linux-next this week, with no

      Pull phase two of __cpuinit removal from Paul Gortmaker:
       "With the __cpuinit infrastructure removed earlier, this group of
        commits only removes the function/data tagging that was done with the
        various (now no-op) __cpuinit related prefixes.
      
        Now that the dust has settled with yesterday's v3.11-rc1, there
        hopefully shouldn't be any new users leaking back in tree, but I think
        we can leave the harmless no-op stubs there for a release as a
        courtesy to those who still have out of tree stuff and weren't paying
        attention.
      
        Although the commits are against the recent tag to allow for minor
        context refreshes for things like yesterday's v3.11-rc1~ slab content,
        the patches have been largely unchanged for weeks, aside from such
        trivial updates.

        involvement required to shepherd such a treewide change to completion.

      md/raid1: fix bio handling problems in process_checks() · 30bc9b53
      NeilBrown authored
      Recent change to use bio_copy_data() in raid1 when repairing
      an array is faulty.
      
      The underlying may have changed the bio in various ways using
      bio_advance and these need to be undone not just for the 'sbio' which
      is being copied to, but also the 'pbio' (primary) which is being
      copied from.
      
      So perform the reset on all bios that were read from and do it early.
      
      This also ensure that the sbio->bi_io_vec[j].bv_len passed to
      memcmp is correct.
      
      This fixes a crash during a 'check' of a RAID1 array.  The crash was
      introduced in 3.10 so this is suitable for 3.10-stable.
