Remove the FLAGS_NEW_KEY logic as it has the following issues:
- the wrong key may end up being used when there are multiple data streams:
t1 t2
setkey()
encrypt()
setkey()
encrypt()
encrypt() <--- key from t2 is used
- switching between encryption and decryption with the same key is not
possible, as the hdr flags are only updated when a new setkey() is
performed
With this change, the key is always sent along with the cryptdata when
performing encryption/decryption operations.

In the scenario where the accelerator business is fully loaded.
When the workqueue receiving messages and performing callback
processing, there are a large number of messages that need to be
received, and there are continuously messages that have been
processed and need to be received.
This will cause the receive loop here to be locked for a long time.
This scenario will cause watchdog timeout problems on OS with kernel
preemption turned off.

[ Upstream commit 203b01001c ]
If a request has the flag CRYPTO_TFM_REQ_MAY_BACKLOG set, the function
qat_alg_send_message_maybacklog(), enqueues it in a backlog list if
either (1) there is already at least one request in the backlog list, or
(2) the HW ring is nearly full or (3) the enqueue to the HW ring fails.
If an interrupt occurs right before the lock in qat_alg_backlog_req() is
taken and the backlog queue is being emptied, then there is no request
in the HW queues that can trigger a subsequent interrupt that can clear
the backlog queue. In addition subsequent requests are enqueued to the
backlog list and not sent to the hardware.
Fix it by holding the lock while taking the decision if the request
needs to be included in the backlog queue or not. This synchronizes the
flow with the interrupt handler that drains the backlog queue.
For performance reasons, the logic has been changed to try to enqueue
first without holding the lock.

QAT GEN4 devices support chained compression operations. These
allow, with a single request to firmware, to hash then compress
data.
Extend the configuration to enable such mode. The cfg_services
operations in sysfs are extended to allow the string "dcc". When
selected, the driver downloads to the device both the symmetric
crypto and the compression firmware images and sends an admin message
to firmware which enables `chained` operations.
In addition, it sets the device's capabilities as the combination
of compression and symmetric crypto capabilities, while excluding
the ICP_ACCEL_CAPABILITIES_CRYPTO_SYMMETRIC bit to indicate
that in this mode, symmetric crypto instances are not supported.
When "dcc" is enabled, the device will handle compression requests
as if the "dc" configuration is loaded ("dcc" is a variation of "dc")
and the driver will register the acomp algorithms.
As for the other extended configurations, "dcc" is only available for
qat_4xxx devices and the chaining service will be only accessible from
user space.

However, if the registration of compression algorithms is not done,

Add a new state, ADF_STATUS_COMPRESSION_ALGS_REGISTERED, which tracks

Commit 1bdc85550a ("crypto: qat - fix concurrency issue when device
state changes") introduced the function adf_dev_down() which wraps the
functions adf_dev_stop() and adf_dev_shutdown().
In a subsequent change, the sequence adf_dev_stop() followed by
adf_dev_shutdown() was then replaced across the driver with just a call
to the function adf_dev_down().
The functions adf_dev_stop() and adf_dev_shutdown() are called in error
paths to stop the accelerator and free up resources and can be called
even if the counterparts adf_dev_init() and adf_dev_start() did not
complete successfully.
However, the implementation of adf_dev_down() prevents the stop/shutdown
sequence if the device is found already down.
For example, if adf_dev_init() fails, the device status is not set as
started and therefore a call to adf_dev_down() won't be calling
adf_dev_shutdown() to undo what adf_dev_init() did.
Do not check if a device is started in adf_dev_down() but do the
equivalent check in adf_sysfs.c when handling a DEV_DOWN command from
the user.

Introduction
===
Currently we are facing some limitations in the caam/jr module lifecycle.
There are some discussion in upstream:
Link: https://lore.kernel.org/linux-crypto/20190904023515.7107-13-andrew.smirnov@gmail.com
Link: https://lore.kernel.org/linux-crypto/20191105151353.6522-1-andrew.smirnov@gmail.com
but in the end it all seems to get down to implementations not being able
to gracefully unregister crypto algorithms from crypto API while there are
users / allocated tfms (cra_refcnt > 1).
[*] OTOH functionalities in caam/jr that don't interact with crypto API
(like Secure Memory or black keys / blobs generation) don't face this
limitation.
Issue at hand
===
When unloading the caam_jr module, the .remove callback for the last JR
device exits with -EBUSY (see "Introduction" above) and doesn't perform
the clean-up (crypto algorithms unregistering etc.).
One side effect of this is leeding to an oops, which occurs due to a
corruption in the linked list of "misc devices"
(drivers/char/misc.c - misc_list):
1. caam_jr module is unloaded without calling unregister_algs()->
caam_keygen_exit()->misc_deregister() for the last job ring device;
this leaves a dangling entry in the misc_list double-linked list
2. rng_core module is unloaded and calls misc_deregister(); this implies
removing the corresponding entry in the misc_list; while doing this the
dangling entry is accessed - which leads to an oops since the address is
no longer valid (address points to the caam_jr module address space,
but caam_jr has been previously unloaded).
Fix this by moving the clean-up of non-crypto related functionalities [*]
before crypto related ones.

CAAM's Black Key mechanism is intended for protection
of user keys against bus snooping. This automatically
encapsulates and decapsulates cryptographic keys ''on-the-fly''
in an encrypted data structure called a Black Key.
Before a value is copied from a Key Register to memory,
CAAM will automatically encrypt the key as a Black Key
(encrypted key) using the current value in the JDKEKR or
TDKEKR as the encryption key.
CAAM's built-in Blob Protocol provides a method for protecting
user-defined data across system power cycles. CAAM protects data
in a data structure called a Blob, which provides both confidentiality
and integrity protection. The data to be protected is encrypted so that
it can be safely placed into non-volatile storage before the SoC is
powered down.
This patch includes the support to generate a black key from random or
from a plaintext. Also one can encapsulate it into a blob or decapsulate
a black key from a blob.
The key and blob generation descriptors are exported into a separate file,
such that they could be shared with other interfaces (qi, qi2).
This feature has support only for black keys, encapsulated in
black blobs in General Memory.
In caamkeyblob_test.c file is a test that validates the above
operations: create a black key from plaintext or from random,
encapsulate and decapsulate a blob and compare the obtained black key.
This test is configured as a kernel module.

Tagged keys are keys that contain metadata indicating what
they are and how to handle them using the new added tag_object API.
A tag object represents the metadata (or simply a header/configuration)
and the actual data (e.g. black key) obtained from hardware.
The support, for tagged keys, to skcipher algorithms, is done by
adding new transformations, with tk prefix to distinguish
between plaintext and tagged keys.
The tk_ transformations can be used directly by their name:
struct sockaddr_alg sa = {
.salg_family = AF_ALG,
.salg_type = "skcipher", /* this selects the symmetric cipher */
.salg_name = "tk(cbc(aes))" /* this is the cipher name */
};
or for dm-crypt, e.g. using dmsetup:
dmsetup -v create encrypted --table "0 $(blockdev --getsz /dev/mmcblk2p10)
crypt capi:tk(cbc(aes))-plain :32:logon:seckey 0 /dev/mmcblk2p10 0 1
sector_size:512".
tk_ transformations will know how to handle tagged keys, by loading the
proper settings for KEY command.
The API expects that the object (the actual data) from a tag object
to be a buffer (defined by address and size).

Some i.MX8 processors, e.g. i.MX8QM (QM, QP), i.MX8QX (QXP, DX) have a
System Controller Firmware (SCFW) running on a dedicated Cortex-M core
that provides power, clock, and resource management.
caam driver needs to be aware of SCU f/w presence, since some things
are done differently:
1. clocks are under SCU f/w control and are turned on automatically
2. there is no access to controller's register page (note however that
some registers are aliased in job rings' register pages)
It's worth mentioning that due to this, MCFGR[PS] cannot be read
and driver assumes MCFGR[PS] = b'0 - engine using 32-bit address pointers.
This is in sync with the limitation imposed by the
SECO (Security Controller) ROM and f/w running on a dedicated Cortex-M.
3. as a consequence of "2.", part of the initialization is moved in
other f/w (SCU, TF-A etc.), e.g. RNG initialization

Merge tag 's390-6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens:
- Add vfio-ap support to pass-through crypto devices to secure
execution guests
- Add API ordinal 6 support to zcrypt_ep11misc device drive, which is
required to handle key generate and key derive (e.g. secure key to
protected key) correctly
- Add missing secure/has_secure sysfs files for the case where it is
not possible to figure where a system has been booted from. Existing
user space relies on that these files are always present
- Fix DCSS block device driver list corruption, caused by incorrect
error handling
- Convert virt_to_pfn() and pfn_to_virt() from defines to static inline
functions to enforce type checking
- Cleanups, improvements, and minor fixes to the kernel mapping setup
- Fix various virtual vs physical address confusions
- Move pfault code to separate file, since it has nothing to do with
regular fault handling
- Move s390 documentation to Documentation/arch/ like it has been done
for other architectures already
- Add HAVE_FUNCTION_GRAPH_RETVAL support
- Factor out the s390_hypfs filesystem and add a new config option for
it. The filesystem is deprecated and as soon as all users are gone it
can be removed some time in the not so near future
- Remove support for old CEX2 and CEX3 crypto cards from zcrypt device
driver
- Add support for user-defined certificates: receive user-defined
certificates with a diagnose call and provide them via 'cert_store'
keyring to user space
- Couple of other small fixes and improvements all over the place

When extending the capability detection logic for 4xxx devices the
SMx algorithms were accidentally missed.
Enable these SMx capabilities by default for QAT GEN4 devices.
Check for device variants where the SMx algorithms are explicitly
disabled by the GEN4 hardware. This is indicated in fusectl1
register.
Mask out SM3 and SM4 based on a bit specific to those algorithms.
Mask out SM2 if the PKE slice is not present.
Fixes: 4b44d28c71 ("crypto: qat - extend crypto capability detection for 4xxx")

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Algorithms must never be added to a driver unless there is a generic
implementation. These truncated versions of sha512 slipped through.
Remove them as they are useless.

The header file jh7110-cryp uses ahash_request without including
crypto/hash.h. Fix that by adding the inclusion.
