[ Upstream commit 0eaef675b94c746900dcea7f6c41b9a103ed5d53 ]
smatch warnings:
drivers/crypto/stm32/stm32-crc32.c:108 stm32_crc_get_next_crc() warn:
can 'crc' even be NULL?
Use list_first_entry_or_null instead of list_first_entry to retrieve
the first device registered.
The function list_first_entry always return a non NULL pointer even if
the list is empty. Hence checking if the pointer returned is NULL does
not tell if the list is empty or not.

[ Upstream commit a3c6f4f4d249cecaf2f34471aadbfb4f4ef57298 ]
When testing sahara sha256 speed performance with tcrypt (mode=404) on
imx53-qsrb board, multiple "Invalid numbers of src SG." errors are
reported. This was traced to sahara_walk_and_recalc() resizing req->src
and causing the subsequent dma_map_sg() call to fail.
Now that the previous commit fixed sahara_sha_hw_links_create() to take
into account the actual request size, rather than relying on sg->length
values, the resize operation is no longer necessary.
Therefore, remove sahara_walk_and_recalc() and simplify associated logic.

In previous capability register implementation, qm irq related values
were read from capability registers dynamically when needed. But in
abnormal scenario, e.g. the core is timeout and the device needs to
soft reset and reset failed after disabling the MSE, the device can
not be removed normally, causing the following call trace:

The reason for this call trace is that when the MSE is disabled, the value
of capability registers in the BAR space become invalid. This will make the
subsequent unregister process get the wrong irq vector through capability
registers and get the wrong irq number by pci_irq_vector().
So add a capability table structure to pre-store the valid value of the irq
information capability register in qm init process, avoid obtaining invalid
capability register value after the MSE is disabled.

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.

The logic that selects the correct adf_fw_config structure based on the
configured service is replicated twice in the uof_get_name() and
uof_get_ae_mask() functions. Refactor the code so that there is no
replication.
This does not introduce any functional change.

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.

The data structure that associates a service id with its name is
replicated across the driver.
Remove duplication by moving this data structure to a new include file,
adf_cfg_services.h in order to have consistency across the drivers.
Note that the data structure is re-instantiated every time the new
include is added to a compilation unit.

If the queue isolation feature is enabled, the number of queues
supported by the device changes. When PF is enabled using the
current default number of queues, the default number of queues may
be greater than the number supported by the device. As a result,
the PF fails to be bound to the driver.
After modification, if queue isolation feature is enabled, when
the default queue parameter is greater than the number supported
by the device, the number of enabled queues will be changed to
the number supported by the device, so that the PF and driver
can be properly bound.

The function adf_dev_init(), through the subsystem qat_compression,
populates the list of list of compression instances
accel_dev->compression_list. If the list of instances is not empty,
the function adf_dev_start() will then call qat_compression_registers()
register the compression algorithms into the crypto framework.
If any of the functions in adf_dev_start() fail, the caller of such
function, in the error path calls adf_dev_down() which in turn call
adf_dev_stop() and adf_dev_shutdown(), see for example the function
state_store in adf_sriov.c.
However, if the registration of compression algorithms is not done,
adf_dev_stop() will try to unregister the algorithms regardless.
This might cause the counter active_devs in qat_compression.c to get
to a negative value.
Add a new state, ADF_STATUS_COMPRESSION_ALGS_REGISTERED, which tracks
if the compression algorithms are registered into the crypto framework.
Then use this to unregister the algorithms if such flag is set. This
ensures that the compression algorithms are only unregistered if
previously registered.

[ Upstream commit c9ca9756f376f51f985130a0e599d956065d4c44 ]
Commit 1bdc85550a2b ("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.
