      lib: make memzero_explicit more robust against dead store elimination · 7829fb09
      Daniel Borkmann 提交于
      In commit 0b053c95 ("lib: memzero_explicit: use barrier instead
      of OPTIMIZER_HIDE_VAR"), we made memzero_explicit() more robust in
      case LTO would decide to inline memzero_explicit() and eventually
      find out it could be elimiated as dead store.
      
      While using barrier() works well for the case of gcc, recent efforts
      from LLVMLinux people suggest to use llvm as an alternative to gcc,
      and there, Stephan found in a simple stand-alone user space example
      that llvm could nevertheless optimize and thus elimitate the memset().
      A similar issue has been observed in the referenced llvm bug report,
      which is regarded as not-a-bug.
      
      Based on some experiments, icc is a bit special on its own, while it
      doesn't seem to eliminate the memset(), it could do so with an own
      implementation, and then result in similar findings as with llvm.
      
      The fix in this patch now works for all three compilers (also tested
      with more aggressive optimization levels). Arguably, in the current
      kernel tree it's more of a theoretical issue, but imho, it's better
      to be pedantic about it.
      
      It's clearly visible with gcc/llvm though, with the below code: if we
      would have used barrier() only here, llvm would have omitted clearing,
      not so with barrier_data() variant:
      
        static inline void memzero_explicit(void *s, size_t count)
        {
          memset(s, 0, count);
          barrier_data(s);
        }
      
        int main(void)
        {
          char buff[20];
          memzero_explicit(buff, sizeof(buff));
          return 0;
        }
      
        $ gcc -O2 test.c
        $ gdb a.out

      As gcc, clang, but also icc defines __GNUC__, it's sufficient to define
      this in compiler-gcc.h only to be picked up. For a fallback or otherwise
      unsupported compiler, we define it as a barrier. Similarly, for ecc which
      does not support gcc inline asm.

      ext4: fix growing of tiny filesystems · 2c869b26
      Jan Kara 提交于
      The estimate of necessary transaction credits in ext4_flex_group_add()
      is too pessimistic. It reserves credit for sb, resize inode, and resize
      inode dindirect block for each group added in a flex group although they
      are always the same block and thus it is enough to account them only
      once. Also the number of modified GDT block is overestimated since we
      fit EXT4_DESC_PER_BLOCK(sb) descriptors in one block.
      
      Make the estimation more precise. That reduces number of requested
      credits enough that we can grow 20 MB filesystem (which has 1 MB
      journal, 79 reserved GDT blocks, and flex group size 16 by default).

      ext4: fix data corruption caused by unwritten and delayed extents · d2dc317d
      Lukas Czerner 提交于
      Currently it is possible to lose whole file system block worth of data
      when we hit the specific interaction with unwritten and delayed extents
      in status extent tree.
      
      The problem is that when we insert delayed extent into extent status
      tree the only way to get rid of it is when we write out delayed buffer.
      However there is a limitation in the extent status tree implementation
      so that when inserting unwritten extent should there be even a single
      delayed block the whole unwritten extent would be marked as delayed.
      
      At this point, there is no way to get rid of the delayed extents,
      because there are no delayed buffers to write out. So when a we write
      into said unwritten extent we will convert it to written, but it still
      remains delayed.
      
      When we try to write into that block later ext4_da_map_blocks() will set
      the buffer new and delayed and map it to invalid block which causes
      the rest of the block to be zeroed loosing already written data.
      
      For now we can fix this by simply not allowing to set delayed status on
      written extent in the extent status tree. Also add WARN_ON() to make
      sure that we notice if this happens in the future.
      
      This problem can be easily reproduced by running the following xfs_io.
      
      xfs_io -f -c "pwrite -S 0xaa 4096 2048" \
                -c "falloc 0 131072" \
                -c "pwrite -S 0xbb 65536 2048" \
                -c "fsync" /mnt/test/fff
      
      echo 3 > /proc/sys/vm/drop_caches
      xfs_io -c "pwrite -S 0xdd 67584 2048" /mnt/test/fff
      
      This can be theoretically also reproduced by at random by running fsx,
      but it's not very reliable, though on machines with bigger page size
      (like ppc) this can be seen more often (especially xfstest generic/127)

      powerpc/powernv: Restore non-volatile CRs after nap · 0aab3747
      Sam Bobroff 提交于
      Patches 7cba160a "powernv/cpuidle: Redesign idle states management"
      and 77b54e9f "powernv/powerpc: Add winkle support for offline cpus"
      use non-volatile condition registers (cr2, cr3 and cr4) early in the system
      reset interrupt handler (system_reset_pSeries()) before it has been determined
      if state loss has occurred. If state loss has not occurred, control returns via
      the power7_wakeup_noloss() path which does not restore those condition
      registers, leaving them corrupted.
      
      Fix this by restoring the condition registers in the power7_wakeup_noloss()
      case.
      
      This is apparent when running a KVM guest on hardware that does not
      support winkle or sleep and the guest makes use of secondary threads. In
      practice this means Power7 machines, though some early unreleased Power8
      machines may also be susceptible.
      
      The secondary CPUs are taken off line before the guest is started and
      they call pnv_smp_cpu_kill_self(). This checks support for sleep
      states (in this case there is no support) and power7_nap() is called.
      
      When the CPU is woken, power7_nap() returns and because the CPU is
      still off line, the main while loop executes again. The sleep states
      support test is executed again, but because the tested values cannot
      have changed, the compiler has optimized the test away and instead we
      rely on the result of the first test, which has been left in cr3
      and/or cr4. With the result overwritten, the wrong branch is taken and
      power7_winkle() is called on a CPU that does not support it, leading
      to it stalling.

      PCI transactions (except PCI config read/write) automatically by
      hardware during reset, which would cause recursive EEH error.
      However, the (software) frozen state EEH_PE_ISOLATED is missed.
      When users get 0xFF from PCI config or MMIO read, EEH_PE_ISOLATED
      is set in PE state retrival backend. Unfortunately, nobody (the
      reset handler or the EEH recovery functinality in host) will clear
      EEH_PE_ISOLATED when the PE has been passed through to guest.
      
      The patch sets and clears EEH_PE_ISOLATED properly during reset
      in function pcibios_set_pcie_reset_state() to fix the issue.

      powerpc/pseries: Correct cpu affinity for dlpar added cpus · f32393c9
      Nathan Fontenot 提交于
      The incorrect ordering of operations during cpu dlpar add results in invalid
      affinity for the cpu being added. The ibm,associativity property in the
      device tree is populated with all zeroes for the added cpu which results in
      invalid affinity mappings and all cpus appear to belong to node 0.
      
      This occurs because rtas configure-connector is called prior to making the
      rtas set-indicator calls. Phyp does not assign affinity information
      for a cpu until the rtas set-indicator calls are made to set the isolation
      and allocation state.
      
      Correct the order of operations to make the rtas set-indicator
      calls (done in dlpar_acquire_drc) before calling rtas configure-connector.

         - Fix for a build problem in ACPICA (with GCC 4.5) introduced by one
           of the recent ACPICA tools commits that added a duplicate typedef
           to one of the ACPICA's header files by mistake (Olaf Hering)
      
         - Fix for a regression in the ACPI SBS (Smart Battery Subsystem)
           driver introduced during the 3.18 development cycle causing the
           smart battery manager to be marked as not present when it should be
           marked as present (Chris Bainbridge)"

       "One nice fix is Peter's patch to make the old good SB Audigy PCI to
        work with 32bit DMA instead of 31bit.  This allows the MIDI synth

        emu10k1 have merged.
      
        In ASoC side, there is one fix in the common code, but it's just
        trivial additions of static inline functions for CONFIG_PM=n.  The
        rest are various device-specific small fixes.

      RGMII-ID uses an internal delay within the transmitter or receiver. This
      feature is phy specific. The rest of the communication is normal RGMII.
      
      So the fec driver has to check for all RGMII modes, not only

      net/mlx4_en: Schedule napi when RX buffers allocation fails · 07841f9d
      Ido Shamay 提交于
      When system is out of memory, refilling of RX buffers fails while
      the driver continue to pass the received packets to the kernel stack.
      At some point, when all RX buffers deplete, driver may fall into a
      sleep, and not recover when memory for new RX buffers is once again
      availible. This is because hardware does not have valid descriptors,
      so no interrupt will be generated for the driver to return to work
      in napi context. Fix it by schedule the napi poll function from
      stats_task delayed workqueue, as long as the allocations fail.
