The patch ad511e260a27b8e35d273cc0ecfe5a8ff9543181 (crypto: qat - Fix incorrect uses of memzero_explicit) broke hashing because the code was in fact overwriting the qat_auth_state variable. In fact there is no reason for the variable to exist anyway since all we are using it for is to store ipad and opad. So we could simply create ipad and opad directly and avoid this whole mess.

2015-01-13crypto: qat - fix device reset flowAllan, Bruce W
When the device needs a reset, e.g. when an uncorrectable PCIe AER event occurs, various services/data structures need to be cleaned up, the hardware reset and the services/data structures initialized and started. The code to perform the cleanup and initialization was not performed when a device reset was done. This patch moves some of the initialization code out of the .probe entry- point into a separate function that is now called during probe as well as after the hardware has been reset. Similarly, a new function is added for first cleaning up these services/data structures prior to resetting. The new functions are adf_dev_init() and adf_dev_shutdown(), respectively, for which there are already prototypes but no actual functions just yet and are now called when the device is reset and during probe/cleanup of the driver. The down and up flows via ioctl calls has similarly been updated. In addition, there are two other bugs in the reset flow - one in the logic for determining whether to schedule a device reset upon receiving an uncorrectable AER event which prevents the reset flow from being initiated, and another with clearing the status bit indicating a device is configured (when resetting the device the configuration remains across the reset so the bit should not be cleared, otherwise, the necessary services will not be re-started in adf_dev_start() after the reset - clear the bit only when actually deleting the configuration).

2015-01-08crypto: qat - Fix incorrect uses of memzero_explicitHerbert Xu
memzero_explicit should only be used on stack variables that get zapped just before they go out of scope. This patch replaces all unnecessary uses of memzero_explicit with memset, removes two memzero_explicit calls altogether as the tfm context comes pre-zeroed, and adds a missing memzero_explicit of the stack variable buff in qat_alg_do_precomputes. The memzeros on ipad/opad + digest_size/auth_keylen are also removed as the entire auth_state is already zeroed on entry.

2014-12-03crypto: sahara - replace tasklets with kthreadSteffen Trumtrar
In preparation for SHA support, replace the tasklets with a kthread that manages one crypto_queue for the core. As the Sahara can only process one AES or SHA request at a time, we make sure that the queue serializes all requests from userspace. Instead of a watchdog timer we now use a completion mechanism in the queue manager thread. This makes the control flow more obvious and guarantees, that only one request is dequeued until the completion is completed.
