Security Fix(es):

  * A flaw was found in the way the Linux kernel's ASN.1 DER decoder
processed certain certificate files with tags of indefinite length. A
local, unprivileged user could use a specially crafted X.509 certificate
DER file to crash the system or, potentially, escalate their privileges on
the system. (CVE-2016-0758, Important)

Red Hat would like to thank Philip Pettersson of Samsung for reporting this
issue.

Bug Fix(es):

  * Under certain conditions, the migration threads could race with the CPU
hotplug, which could cause a deadlock. A set of patches has been provided
to fix this bug, and the deadlock no longer occurs in the system.
(BZ#1299338)

  * A bug in the code that cleans up revoked delegations could previously
cause a soft lockup in the NFS server. This patch fixes the underlying
source code, so the lockup no longer occurs. (BZ#1311582)

  * The second attempt to reload Common Application Programming Interface
(CAPI) devices on the little-endian variant of IBM Power Systems previously
failed. The provided set of patches fixes this bug, and reloading works as
intended. (BZ#1312396)

  * Due to inconsistencies in page size of IOMMU, the NVMe device, and the
kernel, the BUG_ON signal previously occurred in the nvme_setup_prps()
function, leading to the system crash while setting up the DMA transfer.
The provided patch sets the default NVMe page size to 4k, thus preventing
the system crash. (BZ#1312399)

  * Previously, on a system using the Infiniband mlx5 driver used for the SRP
stack, a hard lockup previously occurred after the kernel exceeded time
with lock held with interrupts blocked. As a consequence, the system
panicked. This update fixes this bug, and the system no longer panics in
this situation. (BZ#1313814)

  * On the little-endian variant of IBM Power Systems, the kernel previously
crashed in the bitmap_weight() function while running the memory affinity
script. The provided patch fortifies the topology setup and prevents
sd- child from being set to NULL when it is already NULL. As a result, the
memory affinity script runs successfully. (BZ#1316158)

  * When a KVM guest wrote random values to the special-purpose registers
(SPR) Instruction Authority Mask Register (IAMR), the guest and the
corresponding QEMU process previously hung. This update adds the code which
sets SPRs to a suitable neutral value on guest exit, thus fixing this bug.
(BZ#1316636)

  * Under heavy iSCSI traffic load, the system previously panicked due to a
race in the locking code leading to a ...
