The series adds support to the hmac(shaX) algorithms first, then combines both the Atmel SHA and AES hardware accelerators to implement authenc(hmac(shaX),Y(aes)) algorithms as used by IPSEC/SSL connections. It has also been tested with strongswan + xl2tpd to create an IPSEC+L2TP (transport mode) VPN and strongswan only (tunnel mode) for an IPSEC VPN. Then iperf was used to measure the bandwidth improvement in tunnel mode: drivers AES SHA SPLIP iperf half-duplex Mbit/s authenc(hmac(sha1-generic),cbc(aes)) SW SW N/A 27.7 authenc(hmac(sha1-generic),atmel-cbc-aes) HW SW N/A 30.2 (mainline) authenc(atmel-hmac-sha1,atmel-cbc-aes) HW HW no 29.1 atmel-authenc-hmac-sha1-cbc-aes HW HW yes 38.8 SPLIP: Secure Protocol Layers Improved Performances (AES+SHA combined). Some patches of this series are purely transitional: I've split the modifications into many patches to ease the review. Best regards, Cyrille ChangeLog: v1 -> v2: - add missing drivers/crypto/atmel-authenc.h file in patch 11.
