      net: pch_gbe depends on x86 · f0e61604
      Jiri Slaby authored
      Since 4bb16672 (build some drivers only
      when compile-testing), PTP_1588_CLOCK_PCH depends on (X86 ||
      COMPILE_TEST). But PCH_GBE selects PTP_1588_CLOCK_PCH without
      depending on x86. Fix this by adding the same dependency here.

      The following patchset contains Netfilter fixes for your net tree,
      they are:
      
      * Fix potential NULL dereference in the socket match if revision 0
        is used, from Eric Dumazet.
      
      * Fix missing expectation NAT initialization that results in dumping
        the NAT part via ctnetlink, thus leading to problems in expectation
        synchronization through conntrackd, from myself.

       "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

      rtlwifi: Fix build errors for unusual cases · 6f334c2b
      Larry Finger authored
      The present build configuration for the rtlwifi family of drivers will
      fail under two known conditions:
      
      (1) If rtlwifi is selected without selecting any of the dependent drivers,
          there are errors in the build.
      (2) If the PCI drivers are built into the kernel and the USB drivers are modules,
          or vice versa, there are missing globals.
      
      The first condition is fixed by never building rtlwifi unless at least one
      of the device drivers is selected. The second failure is fixed by splitting
      the PCI and USB codes out of rtlwifi, and creating their own mini drivers.
      If the drivers that use them are modules, they will also be modules.
      
      Although a number of files are touched by this patch, only Makefile and Kconfig
      have undergone significant changes. The only modifications to the other files
      were to export entry points needed by the new rtl_pci and rtl_usb units, or to
      rename two variables that had names that were likely to cause namespace collisions.

      ssb: fix alignment of struct bcma_device_id · b01a60be
      Arnd Bergmann authored
      The ARM OABI and EABI disagree on the alignment of structures
      with small members, so module init tools may interpret the
      ssb device table incorrectly, as shown  by this warning when
      building the b43 device driver in an OABI kernel:
      
      FATAL: drivers/net/wireless/b43/b43: sizeof(struct ssb_device_id)=6 is
      not a modulo of the size of section __mod_ssb_device_table=88.
      
      Forcing the default (EABI) alignment on the structure makes this
      problem go away. Since the ssb_device_id may have the same problem,
      better fix both structures.

      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 :
      
      16:48:00.780413 IP6 2001:16d8:8100:4000:ee1c:0:9d9:bc87 >

      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.

      tuntap: do not zerocopy if iov needs more pages than MAX_SKB_FRAGS · 88529176
      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.

      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
        reported problems"
