      intel_pstate: Fail initialization if P-state information is missing · 98a947ab
      Rafael J. Wysocki authored
      If pstate.current_pstate is 0 after the initial
      intel_pstate_get_cpu_pstates(), this means that we were unable to
      obtain any useful P-state information and there is no reason to
      continue, so free memory and return an error in that case.
      This fixes the following divide error occuring in a nested KVM
      Intel P-state driver initializing.
      Intel pstate controlling: cpu 0
      cpufreq: __cpufreq_add_dev: ->get() failed

      cpufreq: Use CONFIG_CPU_FREQ_DEFAULT_* to set initial policy for setpolicy drivers · a27a9ab7
      Jason Baron authored
      When configuring a default governor (via CONFIG_CPU_FREQ_DEFAULT_*) with the
      intel_pstate driver, the desired default policy is not properly set. For
      example, setting 'CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE' ends up with the
      'powersave' policy being set.
      Fix by configuring the correct default policy, if either 'powersave' or
      'performance' are requested. Otherwise, fallback to what the driver originally
      set via its 'init' routine.

      cpufreq: remove sysfs files for CPUs which failed to come back after resume · 42f921a6
      Viresh Kumar authored
      There are cases where cpufreq_add_dev() may fail for some CPUs
      during system resume. With the current code we will still have
      sysfs cpufreq files for those CPUs and struct cpufreq_policy
      would be already freed for them. Hence any operation on those
      sysfs files would result in kernel warnings.
      Example of problems resulting from resume errors (from Bjørn Mork):
      WARNING: CPU: 0 PID: 6055 at fs/sysfs/file.c:343 sysfs_open_file+0x77/0x212()

       [<ffffffff8138c812>] system_call_fastpath+0x16/0x1b
      To fix this, remove those sysfs files or put the associated kobject
      in case of such errors. Also, to make it simple, remove the cpufreq
      sysfs links from all the CPUs (except for the policy->cpu) during
      suspend, as that operation won't result in a loss of sysfs file
      permissions and we can create those links during resume just fine.

      null_blk: mem garbage on NUMA systems during init · 57053d8c
      Matias Bjorling authored
      For NUMA systems, initializing the blk-mq layer and using per node hctx.
      We initialize submit queues to 1, while blk-mq nr_hw_queues is
      initialized to the number of NUMA nodes.
      This makes the null_init_hctx function overwrite memory outside of what
      it allocated.  In my case it lead to writing garbage into struct
      request_queue's mq_map.

      radeon_pm: fix oops in hwmon_attributes_visible() and radeon_hwmon_show_temp_thresh() · e4158f1b
      Sergey Senozhatsky authored
      Since commit ec39f64b ("drm/radeon/dpm: Convert to use
      devm_hwmon_register_with_groups") radeon_hwmon_init() is using
      hwmon_device_register_with_groups(), which sets `rdev' as a device
      private driver_data, while hwmon_attributes_visible() and
      radeon_hwmon_show_temp_thresh() are still waiting for `drm_device'.
      Fix them by using dev_get_drvdata(), in order to avoid this oops:

       1) Revert CHECKSUM_COMPLETE optimization in pskb_trim_rcsum(), I can't

       3) Freescale FEC driver was DMA mapping the wrong number of bytes, from
          Sebastian Siewior.
       4) Blackhole and prohibit routes in ipv6 were not doing the right thing
          because their ->input and ->output methods were not being assigned
          correctly.  Now they behave properly like their ipv4 counterparts.
          From Kamala R.
       5) Several drivers advertise the NETIF_F_FRAGLIST capability, but
          really do not support this feature and will send garbage packets if
          fed fraglist SKBs.  From Eric Dumazet.
       6) Fix long standing user triggerable BUG_ON over loopback in RDS
          protocol stack, from Venkat Venkatsubra.
       7) Several not so common code paths can potentially try to invoke
          packet scheduler actions that might be NULL without checking.  Shore
          things up by either 1) defining a method as mandatory and erroring
          on registration if that method is NULL 2) defininig a method as
          optional and the registration function hooks up a default
          implementation when NULL is seen.  From Jamal Hadi Salim.
       8) Fix fragment detection in xen-natback driver, from Paul Durrant.
       9) Kill dangling enter_memory_pressure method in cg_proto ops, from
          Eric W Biederman.
      10) SKBs that traverse namespaces should have their local_df cleared,
          from Hannes Frederic Sowa.
      11) IOCB file position is not being updated by macvtap_aio_read() and
          tun_chr_aio_read().  From Zhi Yong Wu.
      12) Don't free virtio_net netdev before releasing all of the NAPI
          instances.  From Andrey Vagin.
      13) Procfs entry leak in xt_hashlimit, from Sergey Popovich.
      14) IPv6 routes that are no cached routes should not count against the
          garbage collection limits.  We had this almost right, but were
          missing handling addrconf generated routes properly.  From Hannes
          Frederic Sowa.
      15) fib{4,6}_rule_suppress() have to consider potentially seeing NULL
          route info when they are called, from Stefan Tomanek.
      16) TUN and MACVTAP have had truncated packet signalling for some time,
          fix from Jason Wang.

      Revert "selinux: consider filesystem subtype in policies" · 29b1deb2
      Linus Torvalds authored
      This reverts commit 102aefdd.
      Tom London reports that it causes sync() to hang on Fedora rawhide:
      and Josh Boyer bisected it down to this commit.  Reverting the commit in
      the rawhide kernel fixes the problem.
      Eric Paris root-caused it to incorrect subtype matching in that commit
      breaking fuse, and has a tentative patch, but by now we're better off
      retrying this in 3.14 rather than playing with it any more.

      igb: Fix for issue where values could be too high for udelay function. · df29df92
      Carolyn Wyborny authored
      This patch changes the igb_phy_has_link function to check the value of the
      parameter before deciding to use udelay or mdelay in order to be sure that
      the value is not too high for udelay function.

      Linus Torvalds authored
      Pull device mapper fixes from Mike Snitzer:
       "A set of device-mapper fixes for 3.13.
        A fix for possible memory corruption during DM table load, fix a
        possible leak of snapshot space in case of a crash, fix a possible
        deadlock due to a shared workqueue in the delay target, fix to
        initialize read-only module parameters that are used to export metrics
        for dm stats and dm bufio.
        Quite a few stable fixes were identified for both the thin-
        provisioning and caching targets as a result of increased regression
        testing using the device-mapper-test-suite (dmts).  The most notable
        of these are the reference counting fixes for the space map btree that
        is used by the dm-array interface -- without these the dm-cache
        metadata will leak, resulting in dm-cache devices running out of
        metadata blocks.  Also, some important fixes related to the
        thin-provisioning target's transition to read-only mode on error"
