      hwmon: (via-cputemp) Use get_online_cpus to avoid races involving CPU hotplug · 1ec3ddfd
      Silas Boyd-Wickizer authored
      
      
      via_cputemp_init loops with for_each_online_cpu, adding
      platform_devices, then calls register_hotcpu_notifier.  If a CPU is
      offlined between the loop and register_hotcpu_notifier, then later
      onlined, via_cputemp_device_add will attempt to add platform devices
      with the same ID.  A similar race occurs during via_cputemp_exit,
      after the module calls unregister_hotcpu_notifier, a CPU might offline
      and a device will exist for a CPU that is offline.
      
      This fix surrounds for_each_online_cpu and register_hotcpu_notifier
      with get_online_cpus+put_online_cpus; and surrounds
      unregister_hotcpu_notifier and device unregistering with
      get_online_cpus+put_online_cpus.
      
      Build tested.

      Linus Torvalds authored
      Pull networking updates from David Miller:
       "More bug fixes, nothing gets past these guys"
      
       1) More kernel info leaks found by Mathias Krause, this time in the
          IPSEC configuration layers.
      
       2) When IPSEC policies change, we do not properly make sure that cached
          routes (which could now be stale) throughout the system will be
          revalidated.  Fix this by generalizing the generation count
          invalidation scheme used by ipv4.  From Nicolas Dichtel.
      
       3) When repairing TCP sockets, we need to allow to restore not just the
          send window scale, but the receive one too.  Extend the existing
          interface to achieve this in a backwards compatible way.  From
          Andrey Vagin.
      
       4) A fix for FCOE scatter gather feature validation erroneously caused
          scatter gather to be disabled for things like AOE too.  From Ed L
          Cashin.
      
       5) Several cases of mishandling of error pointers, from Mathias Krause,
          Wei Yongjun, and Devendra Naga.
      
       6) Fix gianfar build, from Richard Cochran.
      
       7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao
          Hongjiang.
      
       8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder.
      
       9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde.
      
      10) The removal of the conditional compilation of the clk support code
          in the stmmac driver broke things.  This is because the interfaces
          used are the ones that don't also perform the enable/disable of the
          clk.  Fix from Stefan Roese.
      
      11) The QFQ packet scheduler can record out of range virtual start
          times, resulting later in misbehavior and even crashes.  Fix from
          Paolo Valente.
      
      12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the
          receiver when the advertised receive window goes to zero.  Detect
          this case and force the processing of the IOAT DMA queue when it
          happens to avoid getting stuck.  Fix from Michal Kubecek.
      
      13) batman-adv assumes that test_bit() returns only 0 or 1, but this is
          not true for x86 (which returns -1 or 0, via the 'sbb' instruction).
          Fix from Linus Lussing.
      
      14) Fix small packet corruption in e1000, from Tushar Dave.
      
      15) make_blackhole() in the IPSEC policy code can do one read unlock too
          many, fix from Li RongQing.
      
      16) The new tcp_try_coalesce() code introduced a bug in TCP URG
          handling, fix from Eric Dumazet.
      
      17) Fix memory leak in __netif_receive_skb() when doing zerocopy and
          when hit an OOM condition.  From Michael S Tsirkin.
      
      18) netxen blindly deferences pdev->bus->self, which is not guarenteed
          to be non-NULL.  Fix from Nikolay Aleksandrov.
      
      19) Fix a performance regression caused by mistakes in ipv6 checksum
          validation in the bnx2x driver, fix from Michal Schmidt.

      net/stmmac: Use clk_prepare_enable and clk_disable_unprepare · a630844d
      Stefan Roese authored
      This patch fixes an issue introduced by commit ID 6a81c26f
      
      
      [net/stmmac: remove conditional compilation of clk code], which
      switched from the internal stmmac_clk_{en}{dis}able calls to
      clk_{en}{dis}able. By this, calling clk_prepare and clk_unprepare
      was removed.
      
      clk_{un}prepare is mandatory for platforms using common clock framework.
      Since these drivers are used by SPEAr platform, which supports common
      clock framework, add clk_{un}prepare() support for them. Otherwise
      the clocks are not correctly en-/disabled and ethernet support doesn't
      work.

      debugfs: fix u32_array race in format_array_alloc · e05e279e
      Linus Torvalds authored
      
      
      The format_array_alloc() function is fundamentally racy, in that it
      prints the array twice: once to figure out how much space to allocate
      for the buffer, and the second time to actually print out the data.
      
      If any of the array contents changes in between, the allocation size may
      be wrong, and the end result may be truncated in odd ways.
      
      Just don't do it.  Allocate a maximum-sized array up-front, and just
      format the array contents once.  The only user of the u32_array
      interfaces is the Xen spinlock statistics code, and it has 31 entries in
      the arrays, so the maximum size really isn't that big, and the end
      result is much simpler code without the bug.

      This patch fixes a build failure introduced in commit 66636287
      
      
      ("gianfar: Support the get_ts_info ethtool method."). Not only was a
      global variable inconsistently named, but also it was not exported as
      it should have been.
      
      This fix is also needed in stable version 3.5.

      debugfs: fix race in u32_array_read and allocate array at open · 36048853
      David Rientjes authored
      
      
      u32_array_open() is racy when multiple threads read from a file with a
      seek position of zero, i.e. when two or more simultaneous reads are
      occurring after the non-seekable files are created.  It is possible that
      file->private_data is double-freed because the threads races between
      
      	kfree(file->private-data);
      
      and
      
      	file->private_data = NULL;
      
      The fix is to only do format_array_alloc() when the file is opened and
      free it when it is closed.
      
      Note that because the file has always been non-seekable, you can't open
      it and read it multiple times anyway, so the data has always been
      generated just once.  The difference is that now it is generated at open
      time rather than at the time of the first read, and that avoids the
      race.

      bnx2x: remove false warning regarding interrupt number · 185d4c8b
      Ariel Elior authored
      
      
      Since version 7.4 the FW configures in the pci config space the max
      number of interrupts available to the physical function, instead of
      the exact number to use.
      This causes a false warning in driver when comparing the number of
      configured interrupts to the number about to be used.

      net: do not disable sg for packets requiring no checksum · c0d680e5
      Ed Cashin authored
      A change in a series of VLAN-related changes appears to have
      inadvertently disabled the use of the scatter gather feature of
      network cards for transmission of non-IP ethernet protocols like ATA
      over Ethernet (AoE).  Below is a reference to the commit that
      introduces a "harmonize_features" function that turns off scatter
      gather when the NIC does not support hardware checksumming for the
      ethernet protocol of an sk buff.
      
        commit f01a5236
        Author: Jesse Gross <jesse@nicira.com>
        Date:   Sun Jan 9 06:23:31 2011 +0000
      
            net offloading: Generalize netif_get_vlan_features().
      
      The can_checksum_protocol function is not equipped to consider a
      protocol that does not require checksumming.  Calling it for a
      protocol that requires no checksum is inappropriate.
      
      The patch below has harmonize_features call can_checksum_protocol when
      the protocol needs a checksum, so that the network layer is not forced
      to perform unnecessary skb linearization on the transmission of AoE
      packets.  Unnecessary linearization results in decreased performance
      and increased memory pressure, as reported here:
      
        http://www.spinics.net/lists/linux-mm/msg15184.html
      
      The problem has probably not been widely experienced yet, because
      only recently has the kernel.org-distributed aoe driver acquired the
      ability to use payloads of over a page in size, with the patchset
      recently included in the mm tree:
      
        https://lkml.org/lkml/2012/8/28/140
      
      
      
      The coraid.com-distributed aoe driver already could use payloads of
      greater than a page in size, but its users generally do not use the
      newest kernels.
