commit cd26cd65476711e2c69e0a049c0eeef4b743f5ac upstream.
Offset based on (id * size) is wrong for sqc and cqc.
(*sqc/*cqc + 1) can already offset sizeof(struct(Xqc)) length.

[ Upstream commit 70199359902f1c7187dcb28a1be679a7081de7cc ]
Resetting the service arbiter config can cause potential issues
related to response ordering and ring flow control check in the
event of AER or device hang. This is because it results in changing
the default response ring size from 32 bytes to 16 bytes. The service
arbiter config reset also disables response ring flow control check.
Thus, by removing this reset we can prevent the service arbiter from
being configured inappropriately, which leads to undesired device
behaviour in the event of errors.

[ Upstream commit 23717055a79981daf7fafa09a4b0d7566f8384aa ]
The debugfs functions are guaranteed to return a valid error code
instead of NULL upon failure. Consequently, the driver can directly
propagate any error returned without additional checks.
Remove the unnecessary `if` statement after debugfs_create_dir(). If
this function fails, the error code is stored in accel_dev->debugfs_dir
and utilized in subsequent debugfs calls.
Additionally, since accel_dev->debugfs_dir is assured to be non-NULL,
remove the superfluous NULL pointer checks within the adf_dbgfs_add()
and adf_dbgfs_rm().

by some callers of ahash_edesc_alloc, but ahash_digest was conspicuously
missing.
In any case, doing it in the allocation function ensures that the
memory is always there.

The qcom-rng driver supports both ACPI and device tree-based systems.
ACPI support was broken when the hw_random interface support was added.
Let's go ahead and fix this by adding the appropriate driver data to the
ACPI match table, and change the of_device_get_match_data() call to
device_get_match_data() so that it will also work on ACPI-based systems.
This fix was boot tested on a Qualcomm Amberwing server (ACPI based) and
on a Qualcomm SA8775p Automotive Development Board (DT based). I also
verified that qcom-rng shows up in /proc/crypto on both systems.

accelerator core reports memory error. Therefore, the driver
needs to inject the qm error to close the master ooo. Currently,
the qm error is injected after stopping queue, memory may be
released immediately after stopping queue, causing the device to
access the released memory. Therefore, error is injected to close master
ooo before stopping queue to ensure that the device does not access

does not need to be reset. If an error occurs in the cluster,

The req_lock is currently implemented as a rw_lock, but there are no
instances where read_lock() is called. This means that the lock is
effectively only used by writers, making it functionally equivalent to
a simple spinlock.
As stated in Documentation/locking/spinlocks.rst:
"Reader-writer locks require more atomic memory operations than simple
spinlocks. Unless the reader critical section is long, you are better
off just using spinlocks."
Since the rw_lock in this case incurs additional atomic memory
operations without any benefit from reader-writer locking, it is more
efficient to replace it with a spinlock. This patch implements that
replacement to optimize the driver's performance.

In case of sev PLATFORM_STATUS failure, sev_get_api_version() fails
resulting in sev_data field of psp_master nulled out. This later becomes
a problem when unloading the ccp module because the device has not been
unregistered (via misc_deregister()) before clearing the sev_data field
of psp_master. As a result, on reloading the ccp module, a duplicate
device issue is encountered as can be seen from the dmesg log below.
on reloading ccp module via modprobe ccp

Introduce pkey base kernel code with a simple pkey handler registry.
Regroup the pkey code into these kernel modules:
- pkey is the pkey api supporting the ioctls, sysfs and in-kernel api.
Also the pkey base code which offers the handler registry and
handler wrapping invocation functions is integrated there. This
module is automatically loaded in via CPU feature if the MSA feature
is available.
- pkey-cca is the CCA related handler code kernel module a offering
CCA specific implementation for pkey. This module is loaded in
via MODULE_DEVICE_TABLE when a CEX[4-8] card becomes available.
- pkey-ep11 is the EP11 related handler code kernel module offering an
EP11 specific implementation for pkey. This module is loaded in via
MODULE_DEVICE_TABLE when a CEX[4-8] card becomes available.
- pkey-pckmo is the PCKMO related handler code kernel module. This
module is loaded in via CPU feature if the MSA feature is available,
but on init a check for availability of the pckmo instruction is
performed.
The handler modules register via a pkey_handler struct at the pkey
base code and the pkey customer (that is currently the pkey api code
fetches a handler via pkey handler registry functions and calls the
unified handler functions via the pkey base handler functions.
As a result the pkey-cca, pkey-ep11 and pkey-pckmo modules get
independent from each other and it becomes possible to write new
handlers which offer another kind of implementation without implicit
dependencies to other handler implementations and/or kernel device
drivers.
For each of these 4 kernel modules there is an individual Kconfig
entry: CONFIG_PKEY for the base and api, CONFIG_PKEY_CCA for the PKEY
CCA support handler, CONFIG_PKEY_EP11 for the EP11 support handler and
CONFIG_PKEY_PCKMO for the pckmo support. The both CEX related handler
modules (PKEY CCA and PKEY EP11) have a dependency to the zcrypt api
of the zcrypt device driver.

Use the generic crypto_authenc_extractkeys helper instead of custom
parsing code that is slightly broken. Also fix a number of memory
leaks by moving memory allocation from setkey to init_tfm (setkey
can be called multiple times over the life of a tfm).
Finally accept all hash key lengths by running the digest over
extra-long keys.
