      crypto: ahash - ensure statesize is non-zero · 8996eafd
      Russell King authored 
      Unlike shash algorithms, ahash drivers must implement export
and import as their descriptors may contain hardware state and
cannot be exported as is.  Unfortunately some ahash drivers did
not provide them and end up causing crashes with algif_hash.

This patch adds a check to prevent these drivers from registering
ahash algorithms until they are fixed.

     changes introduced when adding the bi_error field to bio.

   - DM snapshot fix to only support snapshots that overflow if the

     snapshot status interface change"

      dm snapshot: add new persistent store option to support overflow · b0d3cc01
      Mike Snitzer authored 
      Commit 76c44f6d introduced the possibly for "Overflow" to be reported
by the snapshot device's status.  Older userspace (e.g. lvm2) does not
handle the "Overflow" status response.

Fix this incompatibility by requiring newer userspace code, that can
cope with "Overflow", request the persistent store with overflow support
by using "PO" (Persistent with Overflow) for the snapshot store type.

      iommu/amd: Fix NULL pointer deref on device detach · 5adad991
      Joerg Roedel authored 
      When a device group is detached from its domain, the iommu
core code calls into the iommu driver to detach each device
individually.

Before this functionality went into the iommu core code, it
was implemented in the drivers, also in the AMD IOMMU
driver as the device alias handling code.

This code is still present, as there might be aliases that
don't exist as real PCI devices (and are therefore invisible
to the iommu core code).

Unfortunatly it might happen now, that a device is unbound
multiple times from its domain, first by the alias handling
code and then by the iommu core code (or vice verca).

This ends up in the do_detach function which dereferences
the dev_data->domain pointer. When the device is already
detached, this pointer is NULL and we get a kernel oops.

Removing the alias code completly is not an option, as that
would also remove the code which handles invisible aliases.
The code could be simplified, but this is too big of a
change outside the merge window.

For now, just check the dev_data->domain pointer in
do_detach and bail out if it is NULL.
