      slub: fix off by one in number of slab tests · 8a5b20ae
      Joonsoo Kim 提交于
      min_partial means minimum number of slab cached in node partial list.
      So, if nr_partial is less than it, we keep newly empty slab on node
      partial list rather than freeing it.  But if nr_partial is equal or
      greater than it, it means that we have enough partial slabs so should
      free newly empty slab.  Current implementation missed the equal case so
      if we set min_partial is 0, then, at least one slab could be cached.
      This is critical problem to kmemcg destroying logic because it doesn't
      works properly if some slabs is cached.  This patch fixes this problem.
      
      Fixes 91cb69620284 ("slub: make dead memcg caches discard free slabs
      immediately").

      This happens because init_cma_reserved_pageblock() calls
      __free_one_page() with pageblock_order as page order but it is bigger
      than MAX_ORDER.  This in turn causes accesses past zone->free_list[].
      
      Fix the problem by changing init_cma_reserved_pageblock() such that it
      splits pageblock into individual MAX_ORDER pages if pageblock is bigger
      than a MAX_ORDER page.
      
      In cases where !CONFIG_HUGETLB_PAGE_SIZE_VARIABLE, which is all
      architectures expect for ia64, powerpc and tile at the moment, the
      “pageblock_order > MAX_ORDER” condition will be optimised out since both
      sides of the operator are constants.  In cases where pageblock size is
      variable, the performance degradation should not be significant anyway
      since init_cma_reserved_pageblock() is called only at boot time at most
      MAX_CMA_AREAS times which by default is eight.

      ARM: 8087/1: ptrace: reload syscall number after secure_computing() check · 42309ab4
      Will Deacon 提交于
      On the syscall tracing path, we call out to secure_computing() to allow
      seccomp to check the syscall number being attempted. As part of this, a
      SIGTRAP may be sent to the tracer and the syscall could be re-written by
      a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall
      is ignored by the current code unless TIF_SYSCALL_TRACE is also set on
      the current thread.
      
      This patch slightly reworks the enter path of the syscall tracing code
      so that we always reload the syscall number from
      current_thread_info()->syscall after the potential ptrace traps.

      Commit 1c2f87c2 (ARM: 8025/1: Get rid of meminfo) changed find_limits
      to use memblock_get_current_limit for calculating the max_low pfn.
      nommu targets never actually set a limit on memblock though which
      means memblock_get_current_limit will just return the default
      value. Set the memblock_limit to be the end of DDR to make sure
      bounds are calculated correctly.

      ARM: 8076/1: mm: add support for HW coherent systems in PL310 cache · 98ea2dba
      Thomas Petazzoni 提交于
      When a PL310 cache is used on a system that provides hardware
      coherency, the outer cache sync operation is useless, and can be
      skipped. Moreover, on some systems, it is harmful as it causes
      deadlocks between the Marvell coherency mechanism, the Marvell PCIe
      controller and the Cortex-A9.
      
      To avoid this, this commit introduces a new Device Tree property
      'arm,io-coherent' for the L2 cache controller node, valid only for the
      PL310 cache. It identifies the usage of the PL310 cache in an I/O
      coherent configuration. Internally, it makes the driver disable the
      outer cache sync operation.
      
      Note that technically speaking, a fully coherent system wouldn't
      require any of the other .outer_cache operations. However, in
      practice, when booting secondary CPUs, these are not yet coherent, and
      therefore a set of cache maintenance operations are necessary at this
      point. This explains why we keep the other .outer_cache operations and
      only ->sync is disabled.
      
      While in theory any write to a PL310 register could cause the
      deadlock, in practice, disabling ->sync is sufficient to workaround
      the deadlock, since the other cache maintenance operations are only
      used in very specific situations.
      
      Contrary to previous versions of this patch, this new version does not
      simply NULL-ify the ->sync member, because the l2c_init_data
      structures are now 'const' and therefore cannot be modified, which is
      a good thing. Therefore, this patch introduces a separate
      l2c_init_data instance, called of_l2c310_coherent_data.

      iscsi-target: fix iscsit_del_np deadlock on unload · 81a9c5e7
      Mikulas Patocka 提交于
      On uniprocessor preemptible kernel, target core deadlocks on unload. The
      following events happen:
      * iscsit_del_np is called
      * it calls send_sig(SIGINT, np->np_thread, 1);
      * the scheduler switches to the np_thread
      * the np_thread is woken up, it sees that kthread_should_stop() returns
        false, so it doesn't terminate
      * the np_thread clears signals with flush_signals(current); and goes back
        to sleep in iscsit_accept_np
      * the scheduler switches back to iscsit_del_np
      * iscsit_del_np calls kthread_stop(np->np_thread);
      * the np_thread is waiting in iscsit_accept_np and it doesn't respond to
        kthread_stop
      
      The deadlock could be resolved if the administrator sends SIGINT signal to
      the np_thread with killall -INT iscsi_np
      
      The reproducible deadlock was introduced in commit
      db6077fd, but the thread-stopping code was
      racy even before.
      
      This patch fixes the problem. Using kthread_should_stop to stop the
      np_thread is unreliable, so we test np_thread_state instead. If
      np_thread_state equals ISCSI_NP_THREAD_SHUTDOWN, the thread exits.

          vhost-scsi: Include prot_bytes into expected data transfer length
      in target-pending makes drivers/vhost/scsi.c call memcpy_fromiovecend().
      This function is not available when CONFIG_NET is not enabled.
      
      socket.h already includes uio.h, so no callers need updating.

      iscsi-target: Avoid rejecting incorrect ITT for Data-Out · 97c99b47
      Nicholas Bellinger 提交于
      This patch changes iscsit_check_dataout_hdr() to dump the incoming
      Data-Out payload when the received ITT is not associated with a
      WRITE, instead of calling iscsit_reject_cmd() for the non WRITE
      ITT descriptor.
      
      This addresses a bug where an initiator sending an Data-Out for
      an ITT associated with a READ would end up generating a reject
      for the READ, eventually resulting in list corruption.

      lz4: fix another possible overrun · 4148c1f6
      Greg Kroah-Hartman 提交于
      There is one other possible overrun in the lz4 code as implemented by
      Linux at this point in time (which differs from the upstream lz4
      codebase, but will get synced at in a future kernel release.)  As
      pointed out by Don, we also need to check the overflow in the data
      itself.
      
      While we are at it, replace the odd error return value with just a
      "simple" -1 value as the return value is never used for anything other
      than a basic "did this work or not" check.
