      sfc: Ensure down_write(&filter_sem) and up_write() are matched before calling efx_net_open() · 671b53ee
      Shradha Shah authored
      This patch avoids the double up_write to filter_sem if
      efx_net_open() fails.

      bridge: mdb: zero out the local br_ip variable before use · f1158b74
      Nikolay Aleksandrov authored
      Since commit b0e9a30d ("bridge: Add vlan id to multicast groups")
      there's a check in br_ip_equal() for a matching vlan id, but the mdb
      functions were not modified to use (or at least zero it) so when an
      entry was added it would have a garbage vlan id (from the local br_ip
      variable in __br_mdb_add/del) and this would prevent it from being
      matched and also deleted. So zero out the whole local ip var to protect
      ourselves from future changes and also to fix the current bug, since
      there's no vlan id support in the mdb uapi - use always vlan id 0.
      Example before patch:
      root@debian:~# bridge mdb add dev br0 port eth1 grp 239.0.0.1 permanent
      root@debian:~# bridge mdb
      dev br0 port eth1 grp 239.0.0.1 permanent
      root@debian:~# bridge mdb del dev br0 port eth1 grp 239.0.0.1 permanent
      RTNETLINK answers: Invalid argument
      
      After patch:
      root@debian:~# bridge mdb add dev br0 port eth1 grp 239.0.0.1 permanent
      root@debian:~# bridge mdb

      drivers: net: cpsw: fix crash while accessing second slave ethernet interface · 1973db0d
      Mugunthan V N authored
      When cpsw's number of slave is set to 1 in device tree and while
      accessing second slave ndev and priv in cpsw_tx_interrupt(),
      there is a kernel crash. This is due to cpsw_get_slave_priv()
      not verifying number of slaves while retriving netdev priv and
      returns a invalid memory region. Fixing the issue by introducing
      number of slave check in cpsw_get_slave_priv() and
      cpsw_get_slave_ndev().

      net/tipc: initialize security state for new connection socket · fdd75ea8
      Stephen Smalley authored
      Calling connect() with an AF_TIPC socket would trigger a series
      of error messages from SELinux along the lines of:
      SELinux: Invalid class 0
      type=AVC msg=audit(1434126658.487:34500): avc:  denied  { <unprintable> }
        for pid=292 comm="kworker/u16:5" scontext=system_u:system_r:kernel_t:s0
        tcontext=system_u:object_r:unlabeled_t:s0 tclass=<unprintable>
        permissive=0
      
      This was due to a failure to initialize the security state of the new
      connection sock by the tipc code, leaving it with junk in the security
      class field and an unlabeled secid.  Add a call to security_sk_clone()
      to inherit the security state from the parent socket.

      sfc: add legacy method for changing a PF's MAC address · 7a186f47
      Daniel Pieczko authored
      Some versions of MCFW do not support the MC_CMD_VADAPTOR_SET_MAC
      command, and ENOSYS will be returned.
      
      If the PF created its own vport, the function's datapath must be
      stopped and the vport can be reconfigured to reflect the new MAC
      address.
      
      If the MCFW created the vport for the PF (which is the case when
      the nic_data->vport_mac is blank), nothing further needs to be
      done as the vport is not under the control of the PF.
      
      This only applies to PFs because the MCFW in question does not
      support VFs.

      Re-organize the structure of error handling to avoid having
      to duplicate the netif_err() around the ifdefs.
      
      The only change to the behaviour of the error-handling is that
      the PF's data structure to record VF details should only be
      updated if the original command succeeded.

      bonding: "primary_reselect" with "failure" is not working properly · b5a983f3
      Mazhar Rana authored
      When "primary_reselect" is set to "failure", primary interface should
      not become active until current active slave is down. But if we set first
      member of bond device as a "primary" interface and "primary_reselect"
      is set to "failure" then whenever primary interface's link get back(up)
      it become active slave even if current active slave is still up.
      
      With this patch, "bond_find_best_slave" will not traverse members if
      primary interface is not candidate for failover/reselection and current
      active slave is still up.

      ip_tunnel: fix ipv4 pmtu check to honor inner ip header df · fc24f2b2
      Timo Teräs authored
      Frag needed should be sent only if the inner header asked
      to not fragment. Currently fragmentation is broken if the
      tunnel has df set, but df was not asked in the original
      packet. The tunnel's df needs to be still checked to update
      internally the pmtu cache.
      
      Commit 23a3647b broke it, and this commit fixes
      the ipv4 df check back to the way it was.

      rtnetlink: verify IFLA_VF_INFO attributes before passing them to driver · 4f7d2cdf
      Daniel Borkmann authored
      Jason Gunthorpe reported that since commit c02db8c6 ("rtnetlink: make
      SR-IOV VF interface symmetric"), we don't verify IFLA_VF_INFO attributes
      anymore with respect to their policy, that is, ifla_vfinfo_policy[].
      
      Before, they were part of ifla_policy[], but they have been nested since
      placed under IFLA_VFINFO_LIST, that contains the attribute IFLA_VF_INFO,
      which is another nested attribute for the actual VF attributes such as
      IFLA_VF_MAC, IFLA_VF_VLAN, etc.
      
      Despite the policy being split out from ifla_policy[] in this commit,
      it's never applied anywhere. nla_for_each_nested() only does basic nla_ok()
      testing for struct nlattr, but it doesn't know about the data context and
      their requirements.
      
      Fix, on top of Jason's initial work, does 1) parsing of the attributes
      with the right policy, and 2) using the resulting parsed attribute table
      from 1) instead of the nla_for_each_nested() loop (just like we used to
      do when still part of ifla_policy[]).

      net: fec: Ensure clocks are enabled while using mdio bus · 6c3e921b
      Andrew Lunn authored
      When a switch is attached to the mdio bus, the mdio bus can be used
      while the interface is not open. If the IPG clock is not enabled, MDIO
      reads/writes will simply time out.
      
      Add support for runtime PM to control this clock. Enable/disable this
      clock using runtime PM, with open()/close() and mdio read()/write()
      function triggering runtime PM operations. Since PM is optional, the
      IPG clock is enabled at probe and is no longer modified by
      fec_enet_clk_enable(), thus if PM is not enabled in the kernel, it is
      guaranteed the clock is running when MDIO operations are performed.

      amd-xgbe: Fix DMA API debug warning · cfbfd86b

      When running a kernel configured with CONFIG_DMA_API_DEBUG=y a warning
      is issued:
        DMA-API: device driver tries to sync DMA memory it has not allocated
      
      This warning is the result of mapping the full range of the Rx buffer
      pages allocated and then performing a dma_sync_single_for_cpu against
      a calculated DMA address. The proper thing to do is to use the
      dma_sync_single_range_for_cpu with a base DMA address and an offset.

      rhashtable: fix for resize events during table walk · 142b942a
      Phil Sutter authored
      If rhashtable_walk_next detects a resize operation in progress, it jumps
      to the new table and continues walking that one. But it misses to drop
      the reference to it's current item, leading it to continue traversing
      the new table's bucket in which the current item is sorted into, and
      after reaching that bucket's end continues traversing the new table's
      second bucket instead of the first one, thereby potentially missing
      items.
      
      This fixes the rhashtable runtime test for me. Bug probably introduced
      by Herbert Xu's patch eddee5ba ("rhashtable: Fix walker behaviour during
      rehash") although not explicitly tested.

      masking a few bugs: a missing INIT_LIST_HEAD() call and incorrectly
      using list_del() rather than list_del_init(). The two patches in this
      set fix these, and it'd be nice they could still make it to 4.2-rc1 to
      avoid new bug reports from users.

      In enic_poll, we clean tx and rx queues, when low latency busy socket polling
      is happening, enic_poll will only clean tx queue. After cleaning tx, it should
      return total budget for re-poll.
      
      There is a small window between vnic_intr_unmask() and enic_poll_unlock_napi().
      In this window if an irq occurs and napi is scheduled on different cpu, it tries
      to acquire enic_poll_lock_napi() and fails. Unlock napi_poll before unmasking
      the interrupt.

      Do not change tx wonk done behaviour. Consider only rx work done for completing

       "Replace module_platform_driver with builtin_platform driver in non
        modules.
      
        We see an increasing number of non-modular drivers using
        modular_driver() type register functions.  There are several downsides
        to letting this continue unchecked:
      
         - The code can appear modular to a reader of the code, and they won't
           know if the code really is modular without checking the Makefile
           and Kconfig to see if compilation is governed by a bool or
           tristate.
      
         - Coders of drivers may be tempted to code up an __exit function that
           is never used, just in order to satisfy the required three args of
           the modular registration function.
      
         - Non-modular code ends up including the <module.h> which increases
           CPP overhead that they don't need.
      
         - It hinders us from performing better separation of the module init
           code and the generic init code.
      
        So here we introduce similar macros for builtin drivers.  Then we
        convert builtin drivers (controlled by a bool Kconfig) by making the
        following type of mapping:
      
          module_platform_driver()       --->  builtin_platform_driver()
          module_platform_driver_probe() --->  builtin_platform_driver_probe().
      
        The set of drivers that are converted here are just the ones that
        showed up as relying on an implicit include of <module.h> during a
        pending header cleanup.  So we convert them here vs adding an include
        of <module.h> to non-modular code to avoid compile fails.  Additonal
        conversions can be done asynchronously at any time.
      
        Once again, an unused module_exit function that is removed here
        appears in the diffstat as an outlier wrt all the other changes"

      Pull module_init replacement part two from Paul Gortmaker:
       "Replace module_init with appropriate alternate initcall in non
        modules.
      
        This series converts non-modular code that is using the module_init()
        call to hook itself into the system to instead use one of our
        alternate priority initcalls.
      
        Unlike the previous series that used device_initcall and hence was a
        runtime no-op, these commits change to one of the alternate initcalls,
        because (a) we have them and (b) it seems like the right thing to do.
      
        For example, it would seem logical to use arch_initcall for arch
        specific setup code and fs_initcall for filesystem setup code.
      
        This does mean however, that changes in the init ordering will be
        taking place, and so there is a small risk that some kind of implicit
        init ordering issue may lie uncovered.  But I think it is still better
        to give these ones sensible priorities than to just assign them all to
        device_initcall in order to exactly preserve the old ordering.
      
        Thad said, we have already made similar changes in core kernel code in
        commit c96d6660 ("kernel: audit/fix non-modular users of
        module_init in core code") without any regressions reported, so this
        type of change isn't without precedent.  It has also got the same
        local testing and linux-next coverage as all the other pull requests
        that I'm sending for this merge window have got.

      Pull module_init replacement part one from Paul Gortmaker:
       "Replace module_init with equivalent device_initcall in non modules.
      
        This series of commits converts non-modular code that is using the
        module_init() call to hook itself into the system to instead use
        device_initcall().
      
        The conversion is a runtime no-op, since module_init actually becomes
        __initcall in the non-modular case, and that in turn gets mapped onto
        device_initcall.  A couple files show a larger negative diffstat,
        representing ones that had a module_exit function that we remove here
        vs previously relying on the linker to dispose of it.
      
        We make this conversion now, so that we can relocate module_init from
        init.h into module.h in the future.
      
        The files changed here are just limited to those that would otherwise
        have to add module.h to obviously non-modular code, in order to avoid
        a compile fail, as testing has shown"

      Pull implicit module.h fixes from Paul Gortmaker:
       "Fix up implicit <module.h> users that will break later.
      
        The files changed here are simply modular source files that are
        implicitly relying on <module.h> being present.  We fix them up now,
        so that we can decouple some of the module related init code from the
        core init code in the future.
      
        The addition of the module.h include to several files here is also a
        no-op from a code generation point of view, else there would already
        be compile issues with these files today.
      
        There may be lots more implicit includes of <module.h> in tree, but
        these are the ones that extensive build test coverage has shown that
        must be fixed in order to avoid build breakage fallout for the pending

      Pull __cpuinit removal from Paul Gortmaker:
       "Remove __cpuinit macros and users.
      
        We removed the __cpuinit stuff in 3.11-rc1 with commit 22f0a273
        ("init.h: remove __cpuinit sections from the kernel") but we left some
        no-op stubs as a courtesy to unmerged code.
      
        Here we get rid of the stubs as well, since (as can be seen in these
        changes) they are enabling use cases to sneak back in, primarily from
        older BSP code that has been living out of tree for some time prior to
        getting mainlined.  So we get rid of these "new" users 1st and then
        get rid of the stubs.
      
        Obviously, getting rid of the stubs can't happen until all the users
        are gone, so I had to keep this together as a series, even though some
        of these commits since got picked up into maintainers trees as well.
      
        The nature of this change is such that it should have zero impact on
        the generated runtime.
      
        This is one of several independent cleanup branches aimed at enabling
        better organization in the init.h and module.h code.  They have been
        getting coverage in the linux-next tree for the last month, in
        addition to my local testing, which also covers approximately a half
