Hello, I am running QNAP NAS device with Marvell SoC and having issues with both AES and SHA1 when accelerated through mv_cesa. Both the encryption and hash algorithms work fine for file sizes up to 1920 bytes, while anything greater than that gets broken (comparing AES with openssl and SHA1 output with sha1sum command).
This is what I have done: Back ported the mv_cesa driver from linux-3.4.rc7 to linux-2.6.33.2 Built and insmoded the driver, which loads fine and the algorithms show up in /proc/crypto The kernel/userspace interface is provided by crypto-linux-1.4 Unfortunately, I am unable to test mv_cesa with latest kernel as this device is running linux-2.6.33.2 and QNAP has not made linux-3.x based firmware available. Here's the CPU info: [/share/HDA_DATA/Public/linux-3.4-rc7/drivers/crypto] # cat /proc/cpuinfo Processor : Feroceon 88F6281 rev 1 (v5l) BogoMIPS : 799.53 Features : swp half thumb fastmult edsp CPU implementer : 0x56 CPU architecture: 5TE CPU variant : 0x2 CPU part : 0x131 CPU revision : 1 Hardware : Feroceon-KW ARM Revision : 0000 Serial : 0000000000000000 Do you think this is a genuine bug or an artifact of running mv_cesa under linux-2.6.33.2 ? Thanks for any help/pointers or anything else I can try? --ajay Symform.com -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
