[ Upstream commit 6cb345939b8cc4be79909875276aa9dc87d16757 ]
PCI device 0x1134 shares same register features as PCI device 0x17E0.
Hence reuse same data for the new PCI device ID 0x1134.

commit 8006aff15516a170640239c5a8e6696c0ba18d8e upstream.
According to the review by Bill Cox [1], the Atmel SHA204A random number
generator produces random numbers with very low entropy.
Set the lowest possible entropy for this chip just to be safe.

commit 07bb097b92b987db518e72525b515d77904e966e upstream.
Currently, the ASP primary device check does not have support for PCI
domains, and, as a result, when the system is configured with PCI domains
(PCI segments) the wrong device can be selected as primary. This results
in commands submitted to the device timing out and failing. The device
check also relies on specific device and function assignments that may
not hold in the future.
Fix the primary ASP device check to include support for PCI domains and
to perform proper checking of the Bus/Device/Function positions.

commit e80cf84b608725303113d6fe98bb727bf7b7a40d upstream.
If we encounter an error when registering alorithms with the crypto
framework, we just bail out and don't unregister the ones we
successfully registered in prior iterations of the loop.
Add code that goes back over the algos and unregisters them before
returning an error from qce_register_algs().

commit 49b9258b05b97c6464e1964b6a2fddb3ddb65d17 upstream.
As QCE is an order of magnitude slower than the ARMv8 Crypto Extensions
on the CPU, and is also less well tested, give it a lower priority.
Previously the QCE SHA algorithms had higher priority than the ARMv8 CE
equivalents, and the ciphers such as AES-XTS had the same priority which
meant the QCE versions were chosen if they happened to be loaded later.

[ Upstream commit fd337f852b2677b53d0859a47b58e6e6bd189f30 ]
When the AEAD algorithm is used for encryption or decryption,
the input authentication length varies, the hardware needs to
obtain the input length to pass the integrity check verification.
Currently, the driver uses a fixed authentication length,which
causes decryption failure, so the length configuration is modified.
In addition, the step of setting the auth length is unnecessary,
so it was deleted from the setkey function.

[ 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().

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

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.

[ Upstream commit b04f06fc0243600665b3b50253869533b7938468 ]
The master ooo cannot be completely closed when the
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
the released memory.

[ Upstream commit 145013f723947c83b1a5f76a0cf6e7237d59e973 ]
The timeout threshold of the hpre cluster is 16ms. When the CPU
and device share virtual address, page fault processing time may
exceed the threshold.
In the current test, there is a high probability that the
cluster times out. However, the cluster is waiting for the
completion of memory access, which is not an error, the device
does not need to be reset. If an error occurs in the cluster,
qm also reports the error. Therefore, the cluster timeout
error of hpre can be masked.

[ Upstream commit f0622894c59458fceb33c4197462bc2006f3fc6b ]
The logic that detects pending VF2PF interrupts unintentionally clears
the section of the error mask register(s) not related to VF2PF.
This might cause interrupts unrelated to VF2PF, reported through
errsou3 and errsou5, to be reported again after the execution
of the function disable_pending_vf2pf_interrupts() in dh895xcc
and GEN2 devices.
Fix by updating only section of errmsk3 and errmsk5 related to VF2PF.

During the zip probe process, the debugfs failure does not stop
the probe. When debugfs initialization fails, jumping to the
error branch will also release regs, in addition to its own

As a result, it may be released repeatedly during the regs

commit d3b17c6d9dddc2db3670bc9be628b122416a3d26 upstream.
Using completion_done to determine whether the caller has gone
away only works after a complete call. Furthermore it's still
possible that the caller has not yet called wait_for_completion,
resulting in another potential UAF.
Fix this by making the caller use cancel_work_sync and then freeing
the memory safely.

[ Upstream commit 7d42e097607c4d246d99225bf2b195b6167a210c ]
During the PCI AER system's error recovery process, the kernel driver
may encounter a race condition with freeing the reset_data structure's
memory. If the device restart will take more than 10 seconds the function
scheduling that restart will exit due to a timeout, and the reset_data
structure will be freed. However, this data structure is used for
completion notification after the restart is completed, which leads
to a UAF bug.
This results in a KFENCE bug notice.
BUG: KFENCE: use-after-free read in adf_device_reset_worker+0x38/0xa0 [intel_qat]
Use-after-free read at 0x00000000bc56fddf (in kfence-#142):
adf_device_reset_worker+0x38/0xa0 [intel_qat]
process_one_work+0x173/0x340
To resolve this race condition, the memory associated to the container
of the work_struct is freed on the worker if the timeout expired,
otherwise on the function that schedules the worker.
The timeout detection can be done by checking if the caller is
still waiting for completion or not by using completion_done() function.
