Date: Thu, 24 Jul 2014 10:44:18 -0300 From: Leonidas Da Silva Barbosa <leosilva@...ux.vnet.ibm.com> To: Herbert Xu <herbert@...dor.apana.org.au>, "David S. Miller" <davem@...emloft.net>, linux-crypto@...r.kernel.org, linux-kernel@...r.kernel.org Cc: mhcerri@...ux.vnet.ibm.com, fin@...ux.vnet.ibm.com Subject: [PATCH 0/8] NX crypto driver reestructure This set of patches deals with the reescruture of NX driver replacing the use of spinlocks, that assure crypto context concurrency, by a copy of crypto ctx to another region of memory in order to be used by the current algorithm. As this region of memory tends to be used constantly also was added a kmemcache chunk avoiding the cost of constant allocations. Leonidas Da Silva Barbosa (8): Adding nx_copy_ctx and kmemcache to handle with crypto context Replacing spinlocks by nx_copy_ctx on NX-AES-CBC Replacing spinlocks by nx_copy_ctx on NX-AES-CCM Replacing spinlocks by nx_copy_ctx on NX-AES-CTR Replacing spinlocks by nx_copy_ctx on NX-AES-ECB Replacing spinlocks by nx_copy_ctx on NX-AES-GCM Replacing spinlocks by nx_copy_ctx on NX-AES-XCBC Replacing spinlocks by nx_copy_ctx on NX-SHA256 and NX-SHA512 drivers/crypto/nx/nx-aes-cbc.c | 20 +++++++---- drivers/crypto/nx/nx-aes-ccm.c | 42 ++++++++++++++--------- drivers/crypto/nx/nx-aes-ctr.c | 20 +++++++---- drivers/crypto/nx/nx-aes-ecb.c | 20 +++++++---- drivers/crypto/nx/nx-aes-gcm.c | 64 +++++++++++++++++++---------------- drivers/crypto/nx/nx-aes-xcbc.c | 51 ++++++++++++++++------------ drivers/crypto/nx/nx-sha256.c | 70 ++++++++++++++++++++++++--------------- drivers/crypto/nx/nx-sha512.c | 70 ++++++++++++++++++++++++--------------- drivers/crypto/nx/nx.c | 45 ++++++++++++++++++++++++- drivers/crypto/nx/nx.h | 8 +++-- 10 files changed, 259 insertions(+), 151 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
