      iwlwifi: mvm: support dumping UMAC internal txfifos · 5b086414
      Golan Ben-Ami 提交于
      In case of FW error, support dumping the UMAC internal txfifos.
      To do so, support version 2 of shared memory cfg command, which
      contains the sizes of the internal txfifos, and move the command
      to the system group.

      iwlwifi: mvm: make sure FW contains the right amount of paging sections · cd47a3d3
      Matti Gottlieb 提交于
      Paging contains 3 sections in the fw. The first for the paging separator,
      The second for the CSS block, the third with the paging data.
      
      Currently if the driver finds the paging separator, and there is only
      section left (CSS), once reading the CSS section, the driver will
      attempt to read the paging data and will go out of the arrays bounds.
      
      Make sure that the FW image contains the right amount of sections for
      paging.

      iwlwifi: mvm: Decrease size of the paging download buffer · c94d7996
      Matti Gottlieb 提交于
      Currently the driver has 2 buffers for paging:
      1. paging db - this contains all of the pages that were in the FW
      image, that the driver stores for the FW. This is allocated for each
      block separately (not contiguous).
      2. download buffer - we need to provide this empty buffer for the
      iwl_sdio_load_fw_chunk function to copy the requested pages to the shared
      memory. This is one big buffer of contiguous memory whose size is the
      size of all the blocks that the fw paging section can contain.
      
      This download buffer size is too big, and causes the allocation to fail
      sometimes. Since the driver allocates memory for each block separately,
      it is not possible for the FW to request all of the pages in one request
      (the FW gives an address and size, so blocks need to be contiguous for
      this to happen), therefore the FW is limited to request only one block.
      
      Decrease the size of the paging download buffer to be the size of a
      paging block.

      Pull networking updates from David Miller:
       "Highlights:
      
         1) Support more Realtek wireless chips, from Jes Sorenson.
      
         2) New BPF types for per-cpu hash and arrap maps, from Alexei
            Starovoitov.
      
         3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
      
         4) Allow the use of SO_REUSEPORT in order to do per-thread processing
         of incoming TCP/UDP connections.  The muxing can be done using a
         BPF program which hashes the incoming packet.  From Craig Gallek.
      
         5) Add a multiplexer for TCP streams, to provide a messaged based
            interface.  BPF programs can be used to determine the message
            boundaries.  From Tom Herbert.
      
         6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
      
         7) Avoid factorial complexity when taking down an inetdev interface
            with lots of configured addresses.  We were doing things like
            traversing the entire address less for each address removed, and
            flushing the entire netfilter conntrack table for every address as
            well.
      
         8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
      
         9) Allow offloading u32 classifiers to hardware, and implement for
            ixgbe, from John Fastabend.
      
        10) Allow configuring IRQ coalescing parameters on a per-queue basis,
            from Kan Liang.
      
        11) Extend ethtool so that larger link mode masks can be supported.
            From David Decotigny.
      
        12) Introduce devlink, which can be used to configure port link types
            (ethernet vs Infiniband, etc.), port splitting, and switch device
            level attributes as a whole.  From Jiri Pirko.
      
        13) Hardware offload support for flower classifiers, from Amir Vadai.
      
        14) Add "Local Checksum Offload".  Basically, for a tunneled packet
            the checksum of the outer header is 'constant' (because with the
            checksum field filled into the inner protocol header, the payload
            of the outer frame checksums to 'zero'), and we can take advantage
            of that in various ways.  From Edward Cree"

      Merge branch 'for-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup · 6b5f04b6
      Linus Torvalds 提交于
      Pull cgroup updates from Tejun Heo:
       "cgroup changes for v4.6-rc1.  No userland visible behavior changes in
        this pull request.  I'll send out a separate pull request for the
        addition of cgroup namespace support.
      
         - The biggest change is the revamping of cgroup core task migration
           and controller handling logic.  There are quite a few places where
           controllers and tasks are manipulated.  Previously, many of those
           places implemented custom operations for each specific use case
           assuming specific starting conditions.  While this worked, it makes
           the code fragile and difficult to follow.
      
           The bulk of this pull request restructures these operations so that
           most related operations are performed through common helpers which
           implement recursive (subtrees are always processed consistently)
           and idempotent (they make cgroup hierarchy converge to the target
           state rather than performing operations assuming specific starting
           conditions).  This makes the code a lot easier to understand,
           verify and extend.
      
         - Implicit controller support is added.  This is primarily for using
           perf_event on the v2 hierarchy so that perf can match cgroup v2
           path without requiring the user to do anything special.  The kernel
           portion of perf_event changes is acked but userland changes are
           still pending review.
      
         - cgroup_no_v1= boot parameter added to ease testing cgroup v2 in
           certain environments.
      
         - There is a regression introduced during v4.4 devel cycle where
           attempts to migrate zombie tasks can mess up internal object
           management.  This was fixed earlier this week and included in this
           pull request w/ stable cc'd.
      
         - Misc non-critical fixes and improvements"

      bonding: fix bond_get_stats() · fe30937b
      Eric Dumazet 提交于
      bond_get_stats() can be called from rtnetlink (with RTNL held)
      or from /proc/net/dev seq handler (with RCU held)
      
      The logic added in commit 5f0c5f73 ("bonding: make global bonding
      stats more reliable") kind of assumed only one cpu could run there.
      
      If multiple threads are reading /proc/net/dev, stats can be really
      messed up after a while.
      
      A second problem is that some fields are 32bit, so we need to properly
      handle the wrap around problem.
      
      Given that RTNL is not always held, we need to use
      bond_for_each_slave_rcu().

      Eli Cohen 提交于
      Commit 85743f1e ("net/mlx4_core: Set UAR page size to 4KB regardless
      of system page size") introduced dependency where old VF drivers without
      this fix fail to load if the PF driver runs with this commit.
      
      To resolve this add a module parameter which disables that functionality
      by default.  If both the PF and VFs are running with a driver with that
      commit the administrator may set the module param to true.
      
      The module parameter is called enable_4k_uar.
