55ece6d9c3 crypto: qat - fix state restore for banks with exceptions
[ Upstream commit 254923ca87 ]

Change the logic in the restore function to properly handle bank
exceptions.

The check for exceptions in the saved state should be performed before
conducting any other ringstat register checks.
If a bank was saved with an exception, the ringstat will have the
appropriate rp_halt/rp_exception bits set, causing the driver to exit
the restore process with an error. Instead, the restore routine should
first check the ringexpstat register, and if any exception was raised,
it should stop further checks and return without any error. In other
words, if a ring pair is in an exception state at the source, it should
be restored the same way at the destination but without raising an error.

Even though this approach might lead to losing the exception state
during migration, the driver will log the exception from the saved state
during the restore process.

a32cd73f66 crypto: qat - allow enabling VFs in the absence of IOMMU
[ Upstream commit 53669ff591 ]

The commit ca88a2bdd4 ("crypto: qat - allow disabling SR-IOV VFs")
introduced an unnecessary change that prevented enabling SR-IOV when
IOMMU is disabled. In certain scenarios, it is desirable to enable
SR-IOV even in the absence of IOMMU. Thus, restoring the previous
functionality to allow VFs to be enumerated in the absence of IOMMU.

e555e28232 crypto: qat - use unmanaged allocation for dc_data
[ Upstream commit 4cc871ad01 ]

The dc_data structure holds data required for handling compression
operations, such as overflow buffers. In this context, the use of
managed memory allocation APIs (devm_kzalloc() and devm_kfree())
is not necessary, as these data structures are freed and
re-allocated when a device is restarted in adf_dev_down() and
adf_dev_up().

Additionally, managed APIs automatically handle memory cleanup when the
device is detached, which can lead to conflicts with manual cleanup
processes. Specifically, if a device driver invokes the adf_dev_down()
function as part of the cleanup registered with
devm_add_action_or_reset(), it may attempt to free memory that is also
managed by the device's resource management system, potentially leading
to a double-free.

This might result in a warning similar to the following when unloading
the device specific driver, for example qat_6xxx.ko:

    qat_free_dc_data+0x4f/0x60 [intel_qat]
    qat_compression_event_handler+0x3d/0x1d0 [intel_qat]
    adf_dev_shutdown+0x6d/0x1a0 [intel_qat]
    adf_dev_down+0x32/0x50 [intel_qat]
    devres_release_all+0xb8/0x110
    device_unbind_cleanup+0xe/0x70
    device_release_driver_internal+0x1c1/0x200
    driver_detach+0x48/0x90
    bus_remove_driver+0x74/0xf0
    pci_unregister_driver+0x2e/0xb0

Use unmanaged memory allocation APIs (kzalloc_node() and kfree()) for
the dc_data structure. This ensures that memory is explicitly allocated
and freed under the control of the driver code, preventing manual
deallocation from interfering with automatic cleanup.

d765505bca crypto: qat - add shutdown handler to qat_dh895xcc
commit 2c4e8b2287 upstream.

During a warm reset via kexec, the system bypasses the driver removal
sequence, meaning that the remove() callback is not invoked.
If a QAT device is not shutdown properly, the device driver will fail to
load in a newly rebooted kernel.

This might result in output like the following after the kexec reboot:

    QAT: AE0 is inactive!!
    QAT: failed to get device out of reset
    dh895xcc 0000:3f:00.0: qat_hal_clr_reset error

    dh895xcc 0000:3f:00.0: probe with driver dh895xcc failed with error -14

Implement the shutdown() handler that hooks into the reboot notifier
list. This brings down the QAT device and ensures it is shut down
properly.

ea3c81acb0 crypto: marvell/cesa - Do not chain submitted requests
commit 0413bcf0fc upstream.

This driver tries to chain requests together before submitting them
to hardware in order to reduce completion interrupts.

However, it even extends chains that have already been submitted
to hardware.  This is dangerous because there is no way of knowing
whether the hardware has already read the DMA memory in question
or not.

Fix this by splitting the chain list into two.  One for submitted
requests and one for requests that have not yet been submitted.
Only extend the latter.

commit 8006aff155 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.

[ Upstream commit 1ddaff40c0 ]

Modifying the crypto_request turns out to be not the right way to handle
the stale value issue with the IV. Though the IV is not used for AES ECB,
it eventually get used in algorithms like LRW in the next step after
AES ECB encryption/decryption. Setting req->iv to NULL breaks the
implementation of such algorithms. Hence modify only the local reqctx
to check for IV.

Currently, the ASP primary device check does not have support for PCI

in commands submitted to the device timing out and failing. The device

This happens because the only async polling without interrupts that
iaa_crypto currently implements is with the 'sync' mode. With 'async',
iaa_crypto calls to compress/decompress submit the descriptor and return
-EINPROGRESS, without any mechanism in the driver to poll for
completions. Hence callers such as test_acomp() in crypto/testmgr.c or
zswap, that wrap the calls to crypto_acomp_compress() and
crypto_acomp_decompress() in synchronous wrappers, will block
indefinitely. Even before zswap can notice this problem, the crypto
testmgr.c's test_acomp() will fail and prevent registration of
"deflate-iaa" as a valid crypto acomp algorithm, thereby disallowing the
use of "deflate-iaa" as a zswap compress (zswap will fall-back to the
default compressor in this case).

To fix this issue, this patch modifies the iaa_crypto sync_mode set
function to treat 'async' equivalent to 'sync', so that the correct and
only supported driver async polling without interrupts implementation is
enabled, and zswap can use 'deflate-iaa' as the compressor.

Hence, with this patch, this is what will happen:

echo async > /sys/bus/dsa/drivers/crypto/sync_mode
cat /sys/bus/dsa/drivers/crypto/sync_mode
sync

There are no crypto/testmgr.c test_acomp() errors, no call traces and zswap
can use 'deflate-iaa' without any errors. The iaa_crypto documentation has
also been updated to mention this caveat with 'async' and what to expect
with this fix.

True iaa_crypto async polling without interrupts is enabled in patch
"crypto: iaa - Implement batch_compress(), batch_decompress() API in
iaa_crypto." [1] which is under review as part of the "zswap IAA compress
batching" patch-series [2]. Until this is merged, we would appreciate it if
this current patch can be considered for a hotfix.

When the AEAD algorithm is used for encryption or decryption,
the input authentication length varies, the hardware needs to

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.
