From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sabrina Dubroca Subject: [PATCH 0/7] crypto: aesni: provide generic gcm(aes) Date: Fri, 28 Apr 2017 18:11:55 +0200 Message-ID: Cc: Sabrina Dubroca , Hannes Frederic Sowa , Herbert Xu , "David S. Miller" , Thomas Gleixner , Ingo Molnar , "H. Peter Anvin" , x86@kernel.org, linux-crypto@vger.kernel.org, linux-kernel@vger.kernel.org To: netdev@vger.kernel.org Return-path: Sender: linux-crypto-owner@vger.kernel.org List-Id: netdev.vger.kernel.org The current aesni AES-GCM implementation only offers support for rfc4106(gcm(aes)). This makes some things a little bit simpler (handling of associated data and authentication tag), but it means that non-IPsec users of gcm(aes) have to rely on gcm_base(ctr-aes-aesni,ghash-clmulni), which is much slower. This patchset adds handling of all valid authentication tag lengths and of any associated data length to the assembly code, and exposes a generic gcm(aes) AEAD algorithm to the crypto API. With these patches, performance of MACsec on a single core increases by 40% (from 4.5Gbps to around 6.3Gbps).
