2020-08-22chelsio/chtls: separate chelsio tls driver from crypto driverVinay Kumar Yadav1-33/+0
chelsio inline tls driver(chtls) is mostly overlaps with NIC drivers but currenty it is part of crypto driver, so move it out to appropriate directory for better maintenance. Signed-off-by: Vinay Kumar Yadav <vinay.yadav@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-11-17crypto: chelsio - switch to skcipher APIArd Biesheuvel1-1/+1
Commit 7a7ffe65c8c5 ("crypto: skcipher - Add top-level skcipher interface") dated 20 august 2015 introduced the new skcipher API which is supposed to replace both blkcipher and ablkcipher. While all consumers of the API have been converted long ago, some producers of the ablkcipher remain, forcing us to keep the ablkcipher support routines alive, along with the matching code to expose [a]blkciphers via the skcipher API. So switch this driver to the skcipher API, allowing us to finally drop the ablkcipher code in the near future.

2016-08-19chcr: Support for Chelsio's Crypto HardwareHariprasad Shenai1-0/+471
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.
