sparc64: Set CRYPTO_TFM_REQ_MAY_SLEEP consistently in CAMELLIA code.

2013-01-11T17:18:51Z

[ Upstream commit 62ba63dc892cf836ecb9ce4fdb7644d45c95070b ] We use the FPU and therefore cannot sleep during the crypto loops. Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

sparc64: Fix AES ctr mode block size.

2013-01-11T17:18:51Z

[ Upstream commit a8d97cef2168ffe5af1aeed6bf6cdc3ce53f3d0b ] Like the generic versions, we need to support a block size of '1' for CTR mode AES. This was discovered thanks to all of the new test cases added by Jussi Kivilinna. Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

sparc64: Fix unrolled AES 256-bit key loops.

2013-01-11T17:18:50Z

[ Upstream commit 9f28ffc03e93343ac04874fda9edb7affea45165 ] The basic scheme of the block mode assembler is that we start by enabling the FPU, loading the key into the floating point registers, then iterate calling the encrypt/decrypt routine for each block. For the 256-bit key cases, we run short on registers in the unrolled loops. So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that get clobbered. The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this. So if we have a mix of multi-block and single-block calls, the single-block unrolled 256-bit encrypt/decrypt can run with some of the key registers clobbered. Handle this by always explicitly loading those registers before using the non-unrolled 256-bit macro. This was discovered thanks to all of the new test cases added by Jussi Kivilinna.

sparc64: Fix build with mix of modular vs. non-modular crypto drivers.

2012-11-10T04:55:16Z

We tried linking in a single built object to hold the device table, but only works if all of the sparc64 crypto modules get built the same way (modular vs. non-modular). Just include the device ID stub into each driver source file so that the table gets compiled into the correct result in all cases. Reported-by: Meelis Roos Signed-off-by: David S. Miller

sparc64: Fix IV handling bug in des_sparc64_cbc_decrypt

2012-09-18T02:57:30Z

The IV wasn't being propagated properly past the first loop iteration. This bug lived only because the crypto layer tests for cbc(des) do not have any cases that go more than one loop. Signed-off-by: David S. Miller

sparc64: Add auto-loading mechanism to crypto-opcode drivers.

2012-09-15T16:46:25Z

Just simply provide a device table containing an entry for sun4v cpus, the capability mask checks in the drivers themselves will take care of the rest. This makes the bootup logs on pre-T4 cpus slightly more verbose, with each driver indicating lack of support for the associated opcode(s). But this isn't too much of a real problem. I toyed with the idea of using explicit entries with compatability fields of "SPARC-T4", "SPARC-T5", etc. but all future cpus will have some subset of these opcodes available and this would just be one more pointless thing to do as each new cpu is released with a new string.
