* | crypto: qat - fix device reset flowAllan, Bruce W2015-01-138-47/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Instead of a watchdog timer we now use a completion mechanism in the queue manager thread.

| * | crypto: caam - fix error reportingCristian Stoica2014-11-061-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error code returned by hardware is four bits wide with an expected zero MSB. A hardware error condition where the error code can get between 0x8 and 0xf will trigger an out of bound array access on the error message table. This patch fixes the invalid array access following such an error and reports the condition.

| * | crypto: caam - add support for givencrypt cbc(aes) and rfc3686(ctr(aes))Catalin Vasile2014-11-061-4/+281
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for one-shot givencrypt algorithms. Givencrypt algorithms will generate their IV and encrypt data within the same shared job descriptors. Current algorithms merged from ablkcipher to givencrypt are: - AES Cipher Block Chaining (CBC) - AES Counter Mode (CTR) compliant with RFC3686 Signed-off-by: Catalin Vasile <catalin.vasile@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | crypto: caam - add support for rfc3686 with authenc md5, sha1 and sha2Catalin Vasile2014-11-061-26/+236
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for AES Counter Mode (CTR) compliant with RFC3686 to be used along with authenc algorithms (md5, sha1, sha224, sha256, sha384, sha512) as one-shot aead algorithms.
