      crypto: xts,lrw - fix out-of-bounds write after kmalloc failure · 9df0eb18
      Eric Biggers authored
      In the generic XTS and LRW algorithms, for input data > 128 bytes, a
      temporary buffer is allocated to hold the values to be XOR'ed with the
      data before and after encryption or decryption.  If the allocation
      fails, the fixed-size buffer embedded in the request buffer is meant to
      be used as a fallback --- resulting in more calls to the ECB algorithm,
      but still producing the correct result.  However, we weren't correctly
      limiting subreq->cryptlen in this case, resulting in pre_crypt()
      overrunning the embedded buffer.  Fix this by setting subreq->cryptlen

      crypto: ccp - Make some CCP DMA channels private · efc989fc
      Gary R Hook authored
      The CCP registers its queues as channels capable of handling
      general DMA operations. The NTB driver will use DMA if
      directed, but as public channels can be reserved for use in
      asynchronous operations some channels should be held back
      as private. Since the public/private determination is
      handled at a device level, reserve the "other" (secondary)
      CCP channels as private.
      Add a module parameter that allows for override, to be
      applied to all channels on all devices.

      padata: avoid race in reordering · de5540d0
      Jason A. Donenfeld authored
      Under extremely heavy uses of padata, crashes occur, and with list
      debugging turned on, this happens instead:
      [87487.298728] WARNING: CPU: 1 PID: 882 at lib/list_debug.c:33

      [87487.361084]  [<ffffffff99ef0055>] padata_do_serial+0xa5/0x120
      padata_reorder calls list_add_tail with the list to which its adding
      locked, which seems correct:
      list_add_tail(&padata->list, &squeue->serial.list);
      This therefore leaves only place where such inconsistency could occur:
      if padata->list is added at the same time on two different threads.
      This pdata pointer comes from the function call to
      padata_get_next(pd), which has in it the following block:
      next_queue = per_cpu_ptr(pd->pqueue, cpu);
      padata = NULL;
      reorder = &next_queue->reorder;
      if (!list_empty(&reorder->list)) {
             padata = list_entry(reorder->list.next,
                                 struct padata_priv, list);
             goto out;
      return padata;
      I strongly suspect that the problem here is that two threads can race
      on reorder list. Even though the deletion is locked, call to
      list_entry is not locked, which means it's feasible that two threads
      pick up the same padata object and subsequently call list_add_tail on
      them at the same time. The fix is thus be hoist that lock outside of
      that block.

      dt-bindings: rng: clocks property on omap_rng not always mandatory · 74d1cf48
      Thomas Petazzoni authored
      Commit 52060836 ("dt-bindings: omap-rng: Document SafeXcel IP-76
      device variant") update the omap_rng Device Tree binding to add support
      for the IP-76 variation of the IP. As part of this change, a "clocks"
      property was added, but is indicated as "Required", without indicated
      it's actually only required for some compatible strings.
      This commit fixes that, by explicitly stating that the clocks property
      is only required with the inside-secure,safexcel-eip76 compatible

      Prarit Bhargava authored
      After commit e9afc746 ("hwrng: geode - Use linux/io.h instead of
      asm/io.h") the geode-rng driver uses devres with pci_dev->dev to keep
      track of resources, but does not actually register a PCI driver.  This
      results in the following issues:
      1.  The driver leaks memory because the driver does not attach to a
      device.  The driver only uses the PCI device as a reference.   devm_*()
      functions will release resources on driver detach, which the geode-rng
      driver will never do.  As a result,
      2.  The driver cannot be reloaded because there is always a use of the
      ioport and region after the first load of the driver.

      Prarit Bhargava authored
      After commit 31b2a73c ("hwrng: amd - Migrate to managed API"), the
      amd-rng driver uses devres with pci_dev->dev to keep track of resources,
      but does not actually register a PCI driver.  This results in the
      following issues:
      1. The message
      WARNING: CPU: 2 PID: 621 at drivers/base/dd.c:349 driver_probe_device+0x38c
      is output when the i2c_amd756 driver loads and attempts to register a PCI
      driver.  The PCI & device subsystems assume that no resources have been
      registered for the device, and the WARN_ON() triggers since amd-rng has
      already do so.
      2.  The driver leaks memory because the driver does not attach to a
      device.  The driver only uses the PCI device as a reference.   devm_*()

      crypto: ccp - Assign DMA commands to the channel's CCP · 7c468447
      Gary R Hook authored
      The CCP driver generally uses a round-robin approach when
      assigning operations to available CCPs. For the DMA engine,
      however, the DMA mappings of the SGs are associated with a
      specific CCP. When an IOMMU is enabled, the IOMMU is
      programmed based on this specific device.
      If the DMA operations are not performed by that specific
      CCP then addressing errors and I/O page faults will occur.
      Update the CCP driver to allow a specific CCP device to be
      requested for an operation and use this in the DMA engine

      Interrupt handling routine was calling req->base.complete() under
      spinlock.  In most cases this wasn't fatal but when combined with some
      of the cipher modes (like LRW) this caused recursion - starting the new
      encryption (s5p_aes_crypt()) while still holding the spinlock from
      previous round (s5p_aes_complete()).
      Beside that, the s5p_aes_interrupt() error handling path could execute
      two completions in case of error for RX and TX blocks.
      Rewrite the interrupt handling routine and the completion by:
      1. Splitting the operations on scatterlist copies from
         s5p_aes_complete() into separate s5p_sg_done(). This still should be
         done under lock.
         The s5p_aes_complete() now only calls req->base.complete() and it has
         to be called outside of lock.
      2. Moving the s5p_aes_complete() out of spinlock critical sections.
         In interrupt service routine s5p_aes_interrupts(), it appeared in few
         places, including error paths inside other functions called from ISR.
         This code was not so obvious to read so simplify it by putting the
         s5p_aes_complete() only within ISR level.

      what kind of information it wants.
      It also allows for some explicit synchronization information to be

      is the cached value ok, or do you need open/close consistency, or what?
