      ARM: Convert to GENERIC_IRQ_MULTI_HANDLER · 4c301f9b
      Palmer Dabbelt authored
      Converts the ARM interrupt code to use the recently added
      GENERIC_IRQ_MULTI_HANDLER, which is essentially just a copy of ARM's
      existhing MULTI_IRQ_HANDLER.  The only changes are:
      
      * handle_arch_irq is now defined in a generic C file instead of an
        arm-specific assembly file.
       
      * handle_arch_irq is now marked as __ro_after_init.

      irqchip: Port the ARM IRQ drivers to GENERIC_IRQ_MULTI_HANDLER · 08fb550c
      Palmer Dabbelt authored
      GENERIC_IRQ_MULTI_HANDLER is incompatible with MULTI_IRQ_HANDLER because
      they define the same symbols.  Multiple generic irqchip drivers select
      MULTI_IRQ_HANDLER, which is now defined on all architectures that
      provide set_handle_irq().
      
      To solve this select GENERIC_IRQ_MULTI_HANDLER for all drivers that used to
      select MULTI_IRQ_HANDLER, but only when MULTI_IRQ_HANDLER doesn't exist.
      
      After that every architecture can be converted over from MULTI_IRQ_HANDLER
      to GENERIC_IRQ_MULTI_HANDLER before removing the extra MULTI_IRQ_HANDLER
      scaffolding.

      genirq: Synchronize only with single thread on free_irq() · 519cc865
      Lukas Wunner authored
      When pciehp is converted to threaded IRQ handling, removal of unplugged
      devices below a PCIe hotplug port happens synchronously in the IRQ thread.
      Removal of devices typically entails a call to free_irq() by their drivers.
      
      If those devices share their IRQ with the hotplug port, __free_irq()
      deadlocks because it calls synchronize_irq() to wait for all hard IRQ
      handlers as well as all threads sharing the IRQ to finish.
      
      Actually it's sufficient to wait only for the IRQ thread of the removed
      device, so call synchronize_hardirq() to wait for all hard IRQ handlers to
      finish, but no longer for any threads.  Compensate by rearranging the
      control flow in irq_wait_for_interrupt() such that the device's thread is
      allowed to run one last time after kthread_stop() has been called.
      
      kthread_stop() blocks until the IRQ thread has completed.  On completion
      the IRQ thread clears its oneshot thread_mask bit.  This is safe because
      __free_irq() holds the request_mutex, thereby preventing __setup_irq() from
      handing out the same oneshot thread_mask bit to a newly requested action.
      
      Stack trace for posterity:

      genirq: Update code comments wrt recycled thread_mask · 836557bd
      Lukas Wunner authored
      Previously a race existed between __free_irq() and __setup_irq() wherein
      the thread_mask of a just removed action could be handed out to a newly
      added action and the freed irq thread would then tread on the oneshot
      mask bit of the newly added irq thread in irq_finalize_oneshot():
      
      time
       |  __free_irq()
       |    raw_spin_lock_irqsave(&desc->lock, flags);
       |    <remove action from linked list>
       |    raw_spin_unlock_irqrestore(&desc->lock, flags);
       |
       |  __setup_irq()
       |    raw_spin_lock_irqsave(&desc->lock, flags);
       |    <traverse linked list to determine oneshot mask bit>
       |    raw_spin_unlock_irqrestore(&desc->lock, flags);
       |
       |  irq_thread() of freed irq (__free_irq() waits in synchronize_irq())
       |    irq_thread_fn()
       |      irq_finalize_oneshot()
       |        raw_spin_lock_irq(&desc->lock);
       |        desc->threads_oneshot &= ~action->thread_mask;
       |        raw_spin_unlock_irq(&desc->lock);
       v
      
      The race was known at least since 2012 when it was documented in a code
      comment by commit e04268b0 ("genirq: Remove paranoid warnons and bogus
      fixups"). The race itself is harmless as nothing touches any of the
      potentially freed data after synchronize_irq().
      
      In 2017 the race was close by commit 9114014c ("genirq: Add mutex to
      irq desc to serialize request/free_irq()"), apparently inadvertantly so
      because the race is neither mentioned in the commit message nor was the
      code comment updated.  Make up for that.

      cifs: Fix invalid check in __cifs_calc_signature() · 83ffdead
      Paulo Alcantara authored
      The following check would never evaluate to true:
        > if (i == 0 && iov[0].iov_len <= 4)
      
      Because 'i' always starts at 1.
      
      This patch fixes it and also move the header checks outside the for loop
      - which makes more sense.

      cifs: Use correct packet length in SMB2_TRANSFORM header · 35e2cc1b
      Paulo Alcantara authored
      In smb3_init_transform_rq(), 'orig_len' was only counting the request
      length, but forgot to count any data pages in the request.
      
      Writing or creating files with the 'seal' mount option was broken.
      
      In addition, do some code refactoring by exporting smb2_rqst_len() to
      calculate the appropriate packet size and avoid duplicating the same
      calculation all over the code.
      
      The start of the io vector is either the rfc1002 length (4 bytes) or a
      SMB2 header which is always > 4. Use this fact to check and skip the
      rfc1002 length if requested.

         - some MAINTAINERS cleanups.
