      mm: memory-failure: use rcu lock instead of tasklist_lock when collect_procs() · d256d1cd
      Tong Tiangen authored
      We found a softlock issue in our test, analyzed the logs, and found that
      the relevant CPU call trace as follows:
      
      CPU0:
        _do_fork
          -> copy_process()
            -> write_lock_irq(&tasklist_lock)  //Disable irq,waiting for
            					 //tasklist_lock
      
      CPU1:
        wp_page_copy()
          ->pte_offset_map_lock()
            -> spin_lock(&page->ptl);        //Hold page->ptl
          -> ptep_clear_flush()
            -> flush_tlb_others() ...
              -> smp_call_function_many()
                -> arch_send_call_function_ipi_mask()
                  -> csd_lock_wait()         //Waiting for other CPUs respond
      	                               //IPI
      
      CPU2:
        collect_procs_anon()
          -> read_lock(&tasklist_lock)       //Hold tasklist_lock
            ->for_each_process(tsk)
              -> page_mapped_in_vma()
                -> page_vma_mapped_walk()
      	    -> map_pte()
                    ->spin_lock(&page->ptl)  //Waiting for page->ptl
      
      We can see that CPU1 waiting for CPU0 respond IPI,CPU0 waiting for CPU2
      unlock tasklist_lock, CPU2 waiting for CPU1 unlock page->ptl. As a result,
      softlockup is triggered.
      
      For collect_procs_anon(), what we're doing is task list iteration, during
      the iteration, with the help of call_rcu(), the task_struct object is freed
      only after one or more grace periods elapse. the logic as follows:
      
      release_task()
        -> __exit_signal()
          -> __unhash_process()
            -> list_del_rcu()
      
        -> put_task_struct_rcu_user()
          -> call_rcu(&task->rcu, delayed_put_task_struct)
      
      delayed_put_task_struct()
        -> put_task_struct()
        -> if (refcount_sub_and_test())
           	__put_task_struct()
                -> free_task()
      
      Therefore, under the protection of the rcu lock, we can safely use
      get_task_struct() to ensure a safe reference to task_struct during the
      iteration.
      
      By removing the use of tasklist_lock in task list iteration, we can break
      the softlock chain above.
      
      The same logic can also be applied to:
       - collect_procs_file()
       - collect_procs_fsdax()
       - collect_procs_ksm()

      Andrew Morton authored
      This warning is telling userspace developers to pass MFD_EXEC and
      MFD_NOEXEC_SEAL to memfd_create().  Commit 434ed335 ("memfd: improve
      userspace warnings for missing exec-related flags") made the warning more
      frequent and visible in the hope that this would accelerate the fixing of
      errant userspace.
      
      But the overall effect is to generate far too much dmesg noise.

      rcu: dump vmalloc memory info safely · c83ad36a
      Zqiang authored
      Currently, for double invoke call_rcu(), will dump rcu_head objects memory
      info, if the objects is not allocated from the slab allocator, the
      vmalloc_dump_obj() will be invoke and the vmap_area_lock spinlock need to
      be held, since the call_rcu() can be invoked in interrupt context,
      therefore, there is a possibility of spinlock deadlock scenarios.

      The previous patch fixes this by using the deadlock-safe best-effort
      version of find_vm_area.  However, in case of failure print the fact that
      the pointer was a vmalloc pointer so that we print at least something.

      mm/vmalloc: add a safer version of find_vm_area() for debug · 0818e739
      Joel Fernandes (Google) authored
      It is unsafe to dump vmalloc area information when trying to do so from
      some contexts.  Add a safer trylock version of the same function to do a
      best-effort VMA finding and use it from vmalloc_dump_obj().

      memcontrol: ensure memcg acquired by id is properly set up · 6f0df8e1
      Johannes Weiner authored
      In the eviction recency check, we attempt to retrieve the memcg to which
      the folio belonged when it was evicted, by the memcg id stored in the
      shadow entry.  However, there is a chance that the retrieved memcg is not
      the original memcg that has been killed, but a new one which happens to
      have the same id.
      
      This is a somewhat unfortunate, but acceptable and rare inaccuracy in the
      heuristics.  However, if we retrieve this new memcg between its allocation
      and when it is properly attached to the memcg hierarchy, we could run into
      the following NULL pointer exception during the memcg hierarchy traversal
      done in mem_cgroup_get_nr_swap_pages():

      The DT of_device.h and of_platform.h date back to the separate

      As part of that merge prepping Arm DT support 13 years ago, they
      "temporarily" include each other. They also include platform_device.h
      and of.h. As a result, there's a pretty much random mix of those include
      files used throughout the tree. In order to detangle these headers and
      replace the implicit includes with struct declarations, users need to
      explicitly include the correct includes.

      Convert platform_get_resource(), devm_ioremap_resource() to a single
      call to devm_platform_get_and_ioremap_resource(), as this is exactly
      what this function does.

       "These are mostly updates of thermal control drivers for ARM platforms,

           Kozlowski)

           already called it, from the Mediatek sensor (Chen Jiahao)

      Pull remoteproc updates from Bjorn Andersson:
       "Support for booting the iMX remoteprocs using MMIO, instead of SMCCC
        is added. The iMX driver is also extended to support delivering
        interrupts from an arbitrary number of vdev.
      
        Support is added to the TI PRU driver, to allow GPMUX to be controlled
        from DeviceTree.
      
        The Qualcomm coredump collector is extended to fall back to generating
        a full coredump, in the case that the loaded firmware doesn't support
        generating minidump. The overly terse MD abbreviation of "MINIDUMP" is
        expanded, to make the code easier on the eye.
      
        The list of Qualcomm Sensor Low Power Island (SLPI) instances
        supported is cleaned up, and SDM845 is added. SDM630/636/660 support
        for the modem subsystem (mss) is added.
      
        All the Qualcomm drivers are transitioned to of_reserved_mem_lookup()
        instead of open coding the resolution of reserved-memory regions, to
        gain handling of error cases. A couple of drivers are transitioned to
        use devm_platform_ioremap_resource_byname().
      
        The stm32 remoteproc driver's PM operations are updated to modern
        macros, to avoid the "unused variable"-warning in some configurations.
      
        Drivers are transitioned away from directly including of_device.h"

      tpm: Enable hwrng only for Pluton on AMD CPUs · 8f7f35e5
      Jarkko Sakkinen authored
      The vendor check introduced by commit 554b841d ("tpm: Disable RNG for
      all AMD fTPMs") doesn't work properly on a number of Intel fTPMs.  On the
      reported systems the TPM doesn't reply at bootup and returns back the
      command code. This makes the TPM fail probe on Lenovo Legion Y540 laptop.
      
      Since only Microsoft Pluton is the only known combination of AMD CPU and
      fTPM from other vendor, disable hwrng otherwise. In order to make sysadmin
      aware of this, print also info message to the klog.
