      UBI: attaching mtd1 to ubi0
      UBI: scanning is finished
      UBI error: init_volumes: not enough PEBs, required 706, available 686
      UBI error: ubi_wl_init: no enough physical eraseblocks (-20, need 1)
      UBI error: ubi_attach_mtd_dev: failed to attach mtd1, error -12 <= NOT ENOMEM
      UBI error: ubi_init: cannot attach mtd1
      
      If available PEBs are not enough when initializing volumes, return -ENOSPC
      directly. If available PEBs are not enough when initializing WL, return
      -ENOSPC instead of -ENOMEM.

      UBI: Validate data_size · 80fe92d4
      Richard Weinberger authored
      commit 281fda27 upstream.
      
      Make sure that data_size is less than LEB size.
      Otherwise a handcrafted UBI image is able to trigger
      an out of bounds memory access in ubi_compare_lebs().

      m68k: Define asmlinkage_protect · 5ae1b59c
      Andreas Schwab authored
      commit 8474ba74 upstream.
      
      Make sure the compiler does not modify arguments of syscall functions.
      This can happen if the compiler generates a tailcall to another
      function.  For example, without asmlinkage_protect sys_openat is compiled
      into this function:
      
      sys_openat:
      	clr.l %d0
      	move.w 18(%sp),%d0
      	move.l %d0,16(%sp)
      	jbra do_sys_open
      
      Note how the fourth argument is modified in place, modifying the register
      %d4 that gets restored from this stack slot when the function returns to
      user-space.  The caller may expect the register to be unmodified across
      system calls.

      perf tools: Fix copying of /proc/kcore · 8b9cce7b
      Adrian Hunter authored
      commit b5cabbcb upstream.
      
      A copy of /proc/kcore containing the kernel text can be made to the
      buildid cache. e.g.
      
      	perf buildid-cache -v -k /proc/kcore
      
      To workaround objdump limitations, a copy is also made when annotating
      against /proc/kcore.
      
      The copying process stops working from libelf about v1.62 onwards (the
      problem was found with v1.63).
      
      The cause is that a call to gelf_getphdr() in kcore__add_phdr() fails
      because additional validation has been added to gelf_getphdr().
      
      The use of gelf_getphdr() is a misguided attempt to get default
      initialization of the Gelf_Phdr structure.  That should not be
      necessary because every member of the Gelf_Phdr structure is
      subsequently assigned.  So just remove the call to gelf_getphdr().
      
      Similarly, a call to gelf_getehdr() in gelf_kcore__init() can be
      removed also.
      
      Committer notes:
      
      Note to stable@kernel.org, from Adrian in the cover letter for this
      patchkit:
      
      The "Fix copying of /proc/kcore" problem goes back to v3.13 if you think
      it is important enough for stable.

      tools lib traceevent: Fix string handling in heterogeneous arch environments · c98cc93e
      Kapileshwar Singh authored
      commit c2e4b24f upstream.
      
      When a trace recorded on a 32-bit device is processed with a 64-bit
      binary, the higher 32-bits of the address need to ignored.
      
      The lack of this results in the output of the 64-bit pointer
      value to the trace as the 32-bit address lookup fails in find_printk().
      
      Before:
      
        burn-1778  [003]   548.600305: bputs:   0xc0046db2s: 2cec5c058d98c
      
      After:
      
        burn-1778  [003]   548.600305: bputs:   0xc0046db2s: RT throttling activated
      
      The problem occurs in PRINT_FIELD when the field is recognized as a
      pointer to a string (of the type const char *)
      
      Heterogeneous architectures cases below can arise and should be handled:
      
      * Traces recorded using 32-bit addresses processed on a 64-bit machine
      * Traces recorded using 64-bit addresses processed on a 32-bit machine

      intel_pstate: Fix overflow in busy_scaled due to long delay · e60f66b5
      Prarit Bhargava authored
      commit 7180dddf upstream.

      being delayed. If this occurs the intel_pstate driver will crash with a

      The duration between reads of the APERF and MPERF registers overflowed a s32
      sized integer in intel_pstate_get_scaled_busy()'s call to div_fp().  The result
      is that int_tofp(duration_us) == 0, and the kernel attempts to divide by 0.
      
      While the kernel shouldn't be delaying for a long time, it can and does
      happen and the intel_pstate driver should not panic in this situation.  This
      patch changes the div_fp() function to use div64_s64() to allow for "long"
      division.  This will avoid the overflow condition on long delays.

      div_s64() accepts the divisor parameter as s32. Helper div_fp()

      multiple skbs") introduced a regression in "ip rule show" - it ends up
      dumping the first rule over and over and never exiting, because 3.19
      and earlier are missing commit 053c095a ("netlink: make
      nlmsg_end() and genlmsg_end() void"), so fib_nl_fill_rule() ends up
      returning skb->len (i.e. > 0) in the success case.
      
      Fix this by checking the return code for < 0 instead of != 0.

      asix: Do full reset during ax88772_bind · 26fc260c
      Charles Keepax authored
      commit 436c2a50 upstream.
      
      commit 3cc81d85 ("asix: Don't reset PHY on if_up for ASIX 88772")
      causes the ethernet on Arndale to no longer function. This appears to
      be because the Arndale ethernet requires a full reset before it will
      function correctly, however simply reverting the above patch causes
      problems with ethtool settings getting reset.
      
      It seems the problem is that the ethernet is not properly reset during
      bind, and indeed the code in ax88772_bind that resets the device is a
      very small subset of the actual ax88772_reset function. This patch uses
      ax88772_reset in place of the existing reset code in ax88772_bind which
      removes some code duplication and fixes the ethernet on Arndale.
      
      It is still possible that the original patch causes some issues with
      suspend and resume but that seems like a separate issue and I haven't
      had a chance to test that yet.

      commit 3cc81d85 upstream.
      
      I've noticed every time the interface is set to 'up,', the kernel
      reports that the link speed is set to 100 Mbps/Full Duplex, even
      when ethtool is used to set autonegotiation to 'off', half
      duplex, 10 Mbps.
      It can be tested by:
       ifconfig eth0 down
       ethtool -s eth0 autoneg off speed 10 duplex half
       ifconfig eth0 up
      
      Then checking 'dmesg' for the link speed.

      jbd2: avoid infinite loop when destroying aborted journal · 4163c028
      Jan Kara authored
      commit 841df7df upstream.
      
      Commit 6f6a6fda "jbd2: fix ocfs2 corrupt when updating journal
      superblock fails" changed jbd2_cleanup_journal_tail() to return EIO
      when the journal is aborted. That makes logic in
      jbd2_log_do_checkpoint() bail out which is fine, except that
      jbd2_journal_destroy() expects jbd2_log_do_checkpoint() to always make
      a progress in cleaning the journal. Without it jbd2_journal_destroy()
      just loops in an infinite loop.
      
      Fix jbd2_journal_destroy() to cleanup journal checkpoint lists of
      jbd2_log_do_checkpoint() fails with error.

      vxlan: set needed headroom correctly · e4f4ae66
      Jiri Benc authored
      commit 9dc2ad10 upstream.
      
      vxlan_setup is called when allocating the net_device, i.e. way before
      vxlan_newlink (or vxlan_dev_configure) is called. This means
      vxlan->default_dst is actually unset in vxlan_setup and the condition that
      sets needed_headroom always takes the else branch.
      
      Set the needed_headrom at the point when we have the information about
      the address family available.

      The i2c5 pinctrl offsets are wrong. If the bootloader doesn't set the

      ASoC: fix broken pxa SoC support · 87d42cac
      Robert Jarzmik authored
      commit 3c8f7710 upstream.
      
      The previous fix of pxa library support, which was introduced to fix the
      library dependency, broke the previous SoC behavior, where a machine
      code binding pxa2xx-ac97 with a coded relied on :
       - sound/soc/pxa/pxa2xx-ac97.c
       - sound/soc/codecs/XXX.c
      
      For example, the mioa701_wm9713.c machine code is currently broken. The
      "select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
      compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
      in sound/arm/Kconfig and sound/soc/pxa/Kconfig.
      
      Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
      pxa2xx-ac97 compilation.
