| * crypto: chelsio - Fix memory corruption in DMA Mapped buffers.Harsh Jain2018-09-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Update PCI Id in "cpl_rx_phys_dsgl" header. In case pci_chan_id and tx_chan_id are not derived from same queue, H/W can send request completion indication before completing DMA Transfer. Herbert, It would be good if fix can be merge to stable tree. For 4.14 kernel, It requires some update to avoid mege conficts.

|/ | | | | | | | | | | | | In the quest to remove all stack VLA usage from the kernel[1], this replaces struct crypto_skcipher and SKCIPHER_REQUEST_ON_STACK() usage with struct crypto_sync_skcipher and SYNC_SKCIPHER_REQUEST_ON_STACK(), which uses a fixed stack size.

* crypto: chcr - Fix txq ids.Harsh Jain2017-04-211-1/+2
| | | | | | | | | | | The patch fixes a critical issue to map txqid with flows on the hardware appropriately, if tx queues created are more than flows configured then txqid shall map within the range of hardware flows configured. This ensure that un-mapped txqid does not remain un-handled. The patch also segregated the rxqid and txqid for clarity.

* chcr: Support for Chelsio's Crypto HardwareHariprasad Shenai2016-08-181-0/+203
The Chelsio's Crypto Hardware can perform the following operations: SHA1, SHA224, SHA256, SHA384 and SHA512, HMAC(SHA1), HMAC(SHA224), HMAC(SHA256), HMAC(SHA384), HAMC(SHA512), AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-XTS, AES-256-XTS This patch implements the driver for above mentioned features. This driver is an Upper Layer Driver which is attached to Chelsio's LLD (cxgb4) and uses the queue allocated by the LLD for sending the crypto requests to the Hardware and receiving the responses from it. The crypto operations can be performed by Chelsio's hardware from the userspace applications and/or from within the kernel space using the kernel's crypto API. The above mentioned crypto features have been tested using kernel's tests mentioned in testmgr.h. They also have been tested from user space using libkcapi and Openssl.
