      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:

      Pull networking fixes from David Miller:
       1) Revert CHECKSUM_COMPLETE optimization in pskb_trim_rcsum(), I can't
          figure out why it breaks things.
       2) Fix comparison in netfilter ipset's hash_netnet4_data_equal(), it
          was basically doing "x == x", from Dave Jones.
       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.
      17) Fix use after frrr in __udp4_lib_rcv(), from Eric Dumazet.
      18) xen-netback does not interpret the NAPI budget properly for TX work,
          fix from Paul Durrant.

      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.

       "A set of device-mapper fixes for 3.13.
        A fix for possible memory corruption during DM table load, fix a

        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

      dm array: fix a reference counting bug in shadow_ablock · ed9571f0
      Joe Thornber authored
      An old array block could have its reference count decremented below
      zero when it is being replaced in the btree by a new array block.
      The fix is to increment the old ablock's reference count just before
      inserting a new ablock into the btree.

      dm space map: disallow decrementing a reference count below zero · 5b564d80
      Joe Thornber authored
      The old behaviour, returning -EINVAL if a ref_count of 0 would be
      decremented, was removed in commit f722063e
       ("dm space map: optimise
      sm_ll_dec and sm_ll_inc").  To fix this regression we return an error
      code from the mutator function pointer passed to sm_ll_mutate() and have
      dec_ref_count() return -EINVAL if the old ref_count is 0.
      Add a DMERR to reflect the potential seriousness of this error.
      Also, add missing dm_tm_unlock() to sm_ll_mutate()'s error path.
      With this fix the following dmts regression test now passes:
       dmtest run --suite cache -n /metadata_use_kernel/
      The next patch fixes the higher-level dm-array code that exposed this
