move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

auto-generated by the following:

for i in `git grep -l -w asm/unaligned.h`; do
	sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
done
for i in `git grep -l -w asm-generic/unaligned.h`; do

crypto: caam/qi* - Use cpumask_var_t instead of cpumask_t

2024-08-10T04:25:34+00:00

Switch cpumask_t to cpumask_var_t as the former may be too big
for the stack:

Also fix the error path handling in qi.c.

crypto: caam: Unembed net_dev structure in dpaa2

2024-07-04T17:19:24+00:00

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_devices from struct dpaa2_caam_priv_per_cpu by
converting them into pointers, and allocating them dynamically. Use the
leverage alloc_netdev_dummy() to allocate the net_device object at
dpaa2_dpseci_setup().

The free of the device occurs at dpaa2_dpseci_disable().

crypto: caam - fix asynchronous hash

2024-01-26T08:35:55+00:00

ahash_alg->setkey is updated to ahash_nosetkey in ahash.c
so checking setkey() function to determine hmac algorithm is not valid.

to fix this added is_hmac variable in structure caam_hash_alg to determine
whether the algorithm is hmac or not.

results in wrong output for encryption/decryption operation.

bus: fsl-mc: Make remove function return void

2023-05-30T23:58:43+00:00

The value returned by an fsl-mc driver's remove function is mostly
ignored.  (Only an error message is printed if the value is non-zero
and then device removal continues unconditionally.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

crypto: caam - Use ahash_request_complete

Instead of calling the base completion function directly, use the
correct ahash helper which is ahash_request_complete.

crypto: caam - Remove GFP_DMA and add DMA alignment padding

2023-01-06T09:15:47+00:00

GFP_DMA does not guarantee that the returned memory is aligned
for DMA.  It should be removed where it is superfluous.

However, kmalloc may start returning DMA-unaligned memory in future
so fix this by adding the alignment by hand.

crypto: caam - Set DMA alignment explicitly

2022-12-02T10:12:41+00:00

This driver has been implicitly relying on kmalloc alignment
to be sufficient for DMA.  This may no longer be the case with
upcoming arm64 changes.

This patch changes it to explicitly request DMA alignment from
the Crypto API.

crypto: caam/qi2 - switch to netif_napi_add_tx_weight()

2022-07-15T08:43:21+00:00

caam has its own special NAPI weights. It's also a crypto device
so presumably it can't be used for packet Rx. Switch to the (new)
correct API.
