aesbs_ecb_encrypt(), aesbs_ecb_decrypt(), aesbs_xts_encrypt(), and aesbs_xts_decrypt() are called via indirect function calls. Therefore they need to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause their type hashes to be emitted when the kernel is built with CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure if the compiler doesn't happen to optimize out the indirect calls. Fixes: c50d3285 ("arm64: Add types to indirect called assembly functions") Cc: stable@vger.kernel.org Signed-off-by:

For multithreaded jobs the computed chunk size is rounded up by the caller-specified alignment. However, the number of worker threads to use is computed using the minimum chunk size without taking alignment into account. A sufficiently large alignment value can result in too many worker threads being allocated for the job. Signed-off-by:

The added 'qcom,qce' compatible value will serve as a sole QCE IP family compatible, since a particular QCE IP version is discoverablem thus, if it'd be needed to differentiate various IP versions, it can be obtained in runtime. Two IP version based compatibles are left untouched to preserve backward DTB ABI compatibility. Signed-off-by:

On certain Snapdragon processors, the crypto engine clocks are enabled by default by security firmware and the driver should not handle the clocks. Make acquiring of all the clocks optional in crypto engine driver, so that the driver initializes properly even if no clocks are specified in the dt. Tested-by:

Crypto engine on certain Snapdragon processors like sm8150, sm8250, sm8350 etc. requires interconnect path between the engine and memory to be explicitly enabled and bandwidth set prior to any operations. Add support in the qce core to enable the interconnect path appropriately. Tested-by:

On newer Qualcomm SoCs the crypto engine clocks are enabled by default by security firmware. To drop clocks and clock-names from the list of required properties use 'qcom,sm8150-qce' compatible name.

Introduce a generic IP family compatible 'qcom,qce' and its two derivatives based on SoC names rather than on IP versions. Having a generic compatible is only partially sufficient, the QCE IP version can be discovered in runtime, however there are two known groups of QCE IP versions, which require different DT properties, these two groups are populated with SoC based compatibles known at the moment. Keep the old compatible 'qcom,crypto-v5.1' and document an existing and already used but not previously documented compatible 'qcom,crypto-v5.4' for backward compatibility of DTB ABI, mark both of the compatibles as deprecated. The change is based on the original one written by Bhupesh Sharma, adding a generic family compatible is suggested by Neil Armstrong.

Move all stat code specific to rng into the rng code. While we're at it, change the stats so that bytes and counts are always incremented even in case of error. This allows the reference counting to be removed as we can now increment the counters prior to the operation. After the operation we simply increase the error count if necessary. This is safe as errors can only occur synchronously (or rather, the existing code already ignored asynchronous errors which are only visible to the callback function). Signed-off-by: -

The stats code resurrected the unions from the early days of kernel crypto. This patch starts the process of moving them out to the individual type structures as we do for everything else. In particular, add a report_stat function to cra_type and call that from the stats code if available. This allows us to move the actual code over one-by-one. Signed-off-by: -

Returning an error value in a platform driver's remove callback results in a generic error message being emitted by the driver core, but otherwise it doesn't make a difference. The device goes away anyhow. As the driver already emits a better error message than the core, suppress the generic error message by returning zero unconditionally. Signed-off-by:

Instead of ignoring errors returned by devm_clk_get() and manually enabling the clk for the whole lifetime of the bound device, use devm_clk_get_optional_enabled(). This is simpler and also more correct as it doesn't ignore errors. This is also more correct because now the call to clk_disable_unprepare() can be dropped from xgene_rng_remove() which happened while the hwrn device was still registered. With the devm callback disabling the clk happens correctly only after devm_hwrng_register() is undone. As a result struct xgene_rng_dev::clk is only used in xgene_rng_probe, and so the struct member can be replaced by a local variable. Signed-off-by:

dev_err_probe simplifies the idiom: if (ret != -EPROBE_DEFER) dev_err(...) return ret; , emits the error code in a human readable way and even yields a useful entry in /sys/kernel/debug/devices_deferred in the EPROBE_DEFER case. So simplify and at the same time improve the driver by using dev_err_probe(). Signed-off-by:

The request flags for acompress is split into two parts. Part of it may be set by the user while the other part (ALLOC_OUTPUT) is managed by the API. This patch makes the split more explicit by not touching the other bits at all in the two "set" functions that let the user modify the flags. Signed-off-by:
