In sctp_setsockopt_bindx()/__sctp_setsockopt_connectx(), it allocates
memory with addrs_size which is passed from userspace. We used flag
GFP_USER to put some more restrictions on it in Commit cacc062152
("sctp: use GFP_USER for user-controlled kmalloc").
However, since Commit c981f254cc ("sctp: use vmemdup_user() rather
than badly open-coding memdup_user()"), vmemdup_user() has been used,
which doesn't check GFP_USER flag when goes to vmalloc_*(). So when
addrs_size is a huge value, it could exhaust memory and even trigger
oom killer.
This patch is to use memdup_user() instead, in which GFP_USER would
work to limit the memory allocation with a huge addrs_size.
Note we can't fix it by limiting 'addrs_size', as there's no demand
for it from RFC.

Added support for AES128-CCM based record encryption. AES128-CCM is
similar to AES128-GCM. Both of them have same salt/iv/mac size. The
notable difference between the two is that while invoking AES128-CCM
operation, the salt||nonce (which is passed as IV) has to be prefixed
with a hardcoded value '2'. Further, CCM implementation in kernel
requires IV passed in crypto_aead_request() to be full '16' bytes.
Therefore, the record structure 'struct tls_rec' has been modified to
reserve '16' bytes for IV. This works for both GCM and CCM based cipher.

Currently the Phy driver's link_change_notify callback is called
whenever the state machine is run (every second if polling), no matter
whether the state changed or not. This isn't needed and may confuse
users considering the name of the callback. Actually it contradicts
its kernel-doc description. Therefore let's change the behavior and
call this callback only in case of an actual state change.
This requires changes to the at803x and rockchip drivers.
at803x can be simplified so that it reacts on a state change to
PHY_NOLINK only.
The rockchip driver can also be much simplified. We simply re-init
the AFE/DSP registers whenever we change to PHY_RUNNING and speed
is 100Mbps. This causes very small overhead because we do this even
if the speed was 100Mbps already. But this is negligible and
I think justified by the much simpler code.
Changes are compile-tested only.
A little bit problematic seems to be to find somebody with the
hardware to test the changes to the two PHY drivers. See also [0].
David may be able to test the Rockchip driver.

We rely on the mmu_notifier call backs to handle the split/merge
of huge pages and thus we are guaranteed that, while creating a
block mapping, either the entire block is unmapped at stage2 or it
is missing permission.
However, we miss a case where the block mapping is split for dirty
logging case and then could later be made block mapping, if we cancel the
dirty logging. This not only creates inconsistent TLB entries for
the pages in the the block, but also leakes the table pages for
PMD level.
Handle this corner case for the huge mappings at stage2 by
unmapping the non-huge mapping for the block. This could potentially
release the upper level table. So we need to restart the table walk
once we unmap the range.

100GbE Intel Wired LAN Driver Updates 2019-03-19
This series contains updates to ice driver only.
Michal adds support for the pruning enable flag to avoid seeing
broadcast packets on different VLANs.
Akeem fixes an issue with VF queues being disabled and the VF netdev
network carrier being lost after reset. Fixed an issue issue when doing
PFR and CORER resets, where all VF VSIs need to be reset and rebuilt
with the main VSIs before replaying all VSIs. Resolved an issue to
properly initialize VFs in the guest OS via PCI passthrough.
Bruce adds a local variable to avoid unnecessary de-references
throughout ice_probe().
Brett cleans up the code a bit by removing the need for a local variable
and re-designs the loop to simply return when get a successful result.
Cleans up the code to replace loop calls with a predefined macro to make
the code more consistent. Updated the driver to ensure ITR granularity
is always 2 usecs. Refactors the calculation of VSIs per PF into a
general function that can calculate per PF allocations for not just VSIs
but across multiple resource types. Improve the driver performance of
the driver when using the default settings by determining the ring size
and the number of descriptors for transmit and receive based on a
calculation with the PAGE_SIZE, ICE_MAX_NUM_DESC, and
ICE_REQ_DESC_MULTIPLE.
Chinh fixes an issue, where a reserved bit was possibly being set when
it should never be set.

Because map updates are distributed lazily, an OSD may not know about
the new blacklist for quite some time after "osd blacklist add" command
is completed. This makes it possible for a blacklisted but still alive
client to overwrite a post-blacklist update, resulting in data
corruption.
Waiting for latest osdmap in ceph_monc_blacklist_add() and thus using
the post-blacklist epoch for all post-blacklist requests ensures that
all such requests "wait" for the blacklist to come into force on their
respective OSDs.
