* crypto: mxs-dcp - Use the devm_clk_get_optional_enabled() helperChristophe JAILLET2023-03-311-16/+5
| | | | | | | | | | Use devm_clk_get_optional_enabled() instead of hand writing it. This saves some loC and improves the semantic. update the error handling path and the remove function accordingly.

* crypto: keembay - Drop if with an always false conditionUwe Kleine-König2023-03-241-2/+0
| | | | | | | | | | | | | | A platform device's remove callback is only ever called after the probe callback returned success. In the case of kmb_ocs_aes_remove() this means that kmb_ocs_aes_probe() succeeded before and so platform_set_drvdata() was called with a non-zero argument and platform_get_drvdata() returns non-NULL. This prepares making remove callbacks return void. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: stm32 - Save and restore between each requestHerbert Xu2023-03-171-108/+56
| | | | | | | | | | | | | | | | | | | | | | The Crypto API hashing paradigm requires the hardware state to be exported between *each* request because multiple unrelated hashes may be processed concurrently. The stm32 hardware is capable of producing the hardware hashing state but it was only doing it in the export function. This is not only broken for export as you can't export a kernel pointer and reimport it, but it also means that concurrent hashing was fundamentally broken. Fix this by moving the saving and restoring of hardware hash state between each and every hashing request.

| | | | | | | | | | | | | | | | | | | | | pci_enable_pcie_error_reporting() enables the device to send ERR_* Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Also remove the corresponding pci_disable_pcie_error_reporting() from the driver .remove() path. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver.

* crypto: qat - fix concurrency issue when device state changesShashank Gupta2023-03-145-20/+73
| | | | | | | | | | | | | | | | | | | | | | | | The sysfs `state` attribute is not protected against race conditions. If multiple processes perform a device state transition on the same device in parallel, unexpected behaviors might occur. For transitioning the device state, adf_sysfs.c calls the functions adf_dev_init(), adf_dev_start(), adf_dev_stop() and adf_dev_shutdown() which are unprotected and interdependent on each other. To perform a state transition, these functions needs to be called in a specific order: * device up: adf_dev_init() -> adf_dev_start() * device down: adf_dev_stop() -> adf_dev_shutdown() This change introduces the functions adf_dev_up() and adf_dev_down() which wrap the state machine functions and protect them with a per-device lock. These are then used in adf_sysfs.c instead of the individual state transition functions.

| | | | | | | | | | | | | | The function adf_sysfs_init() is used by qat_4xxx to create sysfs attributes. This is called by the probe function before starting a device. With this sequence, there might be a chance that the sysfs entries for configuration might be changed by a user while the driver is performing a device bring-up causing unexpected behaviors.
