This patch replaces the seqniv generator with seqiv when the
underlying algorithm understands the new calling convention.
This not only makes more sense as now seqiv is solely responsible
for IV generation rather than also determining how the IV is going
to be used, it also allows for optimisations in the underlying
implementation. For example, the space for the IV could be used
to add padding for authentication.
This patch also removes the unnecessary copying of IV to dst
during seqiv decryption as the IV is part of the AD and not cipher
text.

This patch fixes a bug where we were incorrectly including the
IV in the AD during encryption. The IV must remain in the plain
text for it to be encrypted.
During decryption there is no need to copy the IV to dst because
it's now part of the AD.
This patch removes an unncessary check on authsize which would be
performed by the underlying decrypt call.

This patch fixes a host of reentrancy bugs in the nx driver. The
following algorithms are affected:
* CCM
* GCM
* CTR
* XCBC
* SHA256
* SHA512
The crypto API allows a single transform to be used by multiple
threads simultaneously. For example, IPsec will use a single tfm
to process packets for a given SA. As packets may arrive on
multiple CPUs that tfm must be reentrant.
The nx driver does try to deal with this by using a spin lock.
Unfortunately only the basic AES/CBC/ECB algorithms do this in
the correct way.
The symptom of these bugs may range from the generation of incorrect
output to memory corruption.

Commit 835a6a2f86 ("Bluetooth: Stop sabotaging list poisoning")
thought that the code was sabotaging the list poisoning when NULL'ing
out the list pointers and removed it.
But what was going on was that the bluetooth code was using NULL
pointers for the list as a way to mark it empty, and that commit just
broke it (and replaced the test with NULL with a "list_empty()" test on
a uninitialized list instead, breaking things even further).
So fix it all up to use the regular and real list_empty() handling
(which does not use NULL, but a pointer to itself), also making sure to
initialize the list properly (the previous NULL case was initialized
implicitly by the session being allocated with kzalloc())
This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong
An.

"It's been a busy development cycle for target-core in a number of
different areas.
The fabric API usage for se_node_acl allocation is now within
target-core code, dropping the external API callers for all fabric
drivers tree-wide.
There is a new conversion to RCU hlists for se_node_acl and
se_portal_group LUN mappings, that turns fast-past LUN lookup into a
completely lockless code-path. It also removes the original
hard-coded limitation of 256 LUNs per fabric endpoint.
The configfs attributes for backends can now be shared between core
and driver code, allowing existing drivers to use common code while
still allowing flexibility for new backend provided attributes.

- Merge sbc_verify_dif_* into common code (sagi)
