The AES GCM function (in ccp-ops) requires a fair amount of
stack space, which elicits a complaint when KASAN is enabled.
Rearranging and packing a few structures eliminates the
warning.

This module registers a CRC32 ("Ethernet") and a CRC32C (Castagnoli)
algorithm that make use of the STMicroelectronics STM32 crypto hardware.
Theses algorithms are compatible with the little-endian generic ones.
Both algorithms use ~0 as default seed (key).
With CRC32C the output is xored with ~0.
Using TCRYPT CRC32C speed test, this shows up to 900% speedup compared
to the crc32c-generic algorithm.

Merge the crypto tree to resolve conflict between caam changes.

RNG instantiation was previously fixed by
commit 62743a4145bb9 ("crypto: caam - fix RNG init descriptor ret. code checking")
while deinstantiation was not addressed.
Since the descriptors used are similar, in the sense that they both end
with a JUMP HALT command, checking for errors should be similar too,
i.e. status code 7000_0000h should be considered successful.

The way Job Ring platform devices are created and released does not
allow for multiple create-release cycles.
JR0 Platform device creation error
JR0 Platform device creation error
caam 2100000.caam: no queues configured, terminating
caam: probe of 2100000.caam failed with error -12
The reason is that platform devices are created for each job ring:
for_each_available_child_of_node(nprop, np)
if (of_device_is_compatible(np, "fsl,sec-v4.0-job-ring") ||
of_device_is_compatible(np, "fsl,sec4.0-job-ring")) {
ctrlpriv->jrpdev[ring] =
of_platform_device_create(np, NULL, dev);
which sets OF_POPULATED on the device node, but then it cleans these up:
/* Remove platform devices for JobRs */
for (ring = 0; ring < ctrlpriv->total_jobrs; ring++) {
if (ctrlpriv->jrpdev[ring])
of_device_unregister(ctrlpriv->jrpdev[ring]);
}
which leaves OF_POPULATED set.
Use of_platform_populate / of_platform_depopulate instead.
This allows for a bit of driver clean-up, jrpdev is no longer needed.
Logic changes a bit too:
-exit in case of_platform_populate fails, since currently even QI backend
depends on JR; true, we no longer support the case when "some" of the JR
DT nodes are incorrect
-when cleaning up, caam_remove() would also depopulate RTIC in case
it would have been populated somewhere else - not the case for now

kernelci.org reports a build-time regression on linux-next, with a harmless

The return type for atomic64_read() unfortunately differs between
architectures, with some defining it as atomic_long_read() and others
returning a 64-bit type explicitly. Fixing this in general would be nice,
but also require changing other users of these functions, so the simpler
workaround is to add a cast here that avoids the warnings on the default
build.

Driver is capable of handling only one request at a time and it stores
it in its state container struct s5p_aes_dev. This stored request must be
protected between concurrent invocations (e.g. completing current
request and scheduling new one). Combination of lock and "busy" field
is used for that purpose.
When "busy" field is true, the driver will not accept new request thus
it will not overwrite currently handled data.
However commit 28b62b145868 ("crypto: s5p-sss - Fix spinlock recursion
on LRW(AES)") moved some of the write to "busy" field out of a lock
protected critical section. This might lead to potential race between
completing current request and scheduling a new one. Effectively the
request completion might try to operate on new crypto request.

CAAM engine supports two interfaces for crypto job submission:
-job ring interface - already existing caam/jr driver
-Queue Interface (QI) - caam/qi driver added in current patch
QI is present in CAAM engines found on DPAA platforms.
QI gets its I/O (frame descriptors) from QMan (Queue Manager) queues.
This patch adds a platform device for accessing CAAM's queue interface.
The requests are submitted to CAAM using one frame queue per
cryptographic context. Each crypto context has one shared descriptor.
This shared descriptor is attached to frame queue associated with
corresponding driver context using context_a.
The driver hides the mechanics of FQ creation, initialisation from its
applications. Each cryptographic context needs to be associated with
driver context which houses the FQ to be used to transport the job to
CAAM. The driver provides API for:
(a) Context creation
(b) Job submission
(c) Context deletion
(d) Congestion indication - whether path to/from CAAM is congested
The driver supports affining its context to a particular CPU.
This means that any responses from CAAM for the context in question
would arrive at the given CPU. This helps in implementing one CPU
per packet round trip in IPsec application.
The driver processes CAAM responses under NAPI contexts.
NAPI contexts are instantiated only on cores with affined portals since
only cores having their own portal can receive responses from DQRR.
The responses from CAAM for all cryptographic contexts ride on a fixed
set of FQs. We use one response FQ per portal owning core. The response
FQ is configured in each core's and thus portal's dedicated channel.
This gives the flexibility to direct CAAM's responses for a crypto
context on a given core.

Merging 4.11-rc3 to pick up md5 removal from /dev/random.

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.

This patch refines data structures, which are used to control engine's
data path, to make it more efficient. Hence current change are:
- gathers the broken pieces of structures 'mtk_aes_ct''mtk_aes_tfm'
into struct mtk_aes_info hence avoiding additional DMA-mapping.
- adds 'keymode' in struct mtk_aes_base_ctx. When .setkey() callback is
called, we store keybit setting in keymode. Doing so, there is no need
to check keylen second time in mtk_aes_info_init() / mtk_aes_gcm_info_init().
Besides, this patch also removes unused macro definitions and adds helper
inline function to write security information(key, IV,...) to info->state.

In old code, we must to add one to shift ring to the next segment, and
then use this value to caculate current offset from ring base for each

This is a transitional patch. It merges mtk_sha_xmit() and mtk_sha_xmit2()

In addition, res->buf and cryp->tmp_dma in mtk_sha_xmit() are useless, since

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
support.

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.

In a regular interrupt handler driver was finishing the crypt/decrypt
request by calling complete on crypto request. This is disallowed since
converting to skcipher in commit b286d8b1a690 ("crypto: skcipher - Add
skcipher walk interface") and causes a warning:
WARNING: CPU: 0 PID: 0 at crypto/skcipher.c:430 skcipher_walk_first+0x13c/0x14c
The interrupt is marked shared but in fact there are no other users
sharing it. Thus the simplest solution seems to be to just use a
threaded interrupt handler, after converting it to oneshot.

Pull vhost updates from Michael Tsirkin:
"virtio, vhost: optimizations, fixes
Looks like a quiet cycle for vhost/virtio, just a couple of minor
tweaks. Most notable is automatic interrupt affinity for blk and scsi.
Hopefully other devices are not far behind"
* tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost:
virtio-console: avoid DMA from stack
vhost: introduce O(1) vq metadata cache
virtio_scsi: use virtio IRQ affinity
virtio_blk: use virtio IRQ affinity
blk-mq: provide a default queue mapping for virtio device
virtio: provide a method to get the IRQ affinity mask for a virtqueue
virtio: allow drivers to request IRQ affinity when creating VQs
virtio_pci: simplify MSI-X setup
virtio_pci: don't duplicate the msix_enable flag in struct pci_dev
virtio_pci: use shared interrupts for virtqueues
virtio_pci: remove struct virtio_pci_vq_info
vhost: try avoiding avail index access when getting descriptor
virtio_mmio: expose header to userspace

Pull more s390 updates from Martin Schwidefsky:
"Next to the usual bug fixes (including the TASK_SIZE fix), there is
one larger crypto item. It allows to use protected keys with the
in-kernel crypto API
The protected key support has two parts, the pkey user space API to
convert key formats and the paes crypto module that uses a protected
key instead of a standard AES key"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390: TASK_SIZE for kernel threads

Add a struct irq_affinity pointer to the find_vqs methods, which if set
is used to tell the PCI layer to create the MSI-X vectors for our I/O
virtqueues with the proper affinity from the start. Compared to after
the fact affinity hints this gives us an instantly working setup and
allows to allocate the irq descritors node-local and avoid interconnect
traffic. Last but not least this will allow blk-mq queues are created
based on the interrupt affinity for storage drivers.
