2013-06-05crypto: omap-aes - Don't idle/start AES device between Encrypt operationsJoel A Fernandes
Calling runtime PM API for every block causes serious perf hit to crypto operations that are done on a long buffer. As crypto is performed on a page boundary, encrypting large buffers can cause a series of crypto operations divided by page. The runtime PM API is also called those many times. We call runtime_pm_get_sync only at beginning on the session (cra_init) and runtime_pm_put at the end. This result in upto a 50% speedup as below. This doesn't make the driver to keep the system awake as runtime get/put is only called during a crypto session which completes usually quickly.

2013-05-28crypto: dcp - Added support for Freescale's DCP co-processorTobias Rauter
This patch enables the DCP crypto functionality on imx28. Currently, only aes-128-cbc is supported. Moreover, the dcpboot misc-device, which is used by Freescale's SDK tools and uses a non-software-readable OTP-key, is added. Changes of v2: - ring buffer for hardware-descriptors - use of ablkcipher walk - OTP key encryption/decryption via misc-device (compatible to Freescale-SDK) - overall cleanup The DCP is also capable of sha1/sha256 but I won't be able to add that anytime soon. Tested with built-in runtime-self-test, tcrypt and openssl via cryptodev 1.6 on imx28-evk and a custom built imx28-board.

Fixes a race on driver init with registering algorithms where the driver status flag wasn't being set before self testing started. Added the cra_alignmask field for CBC and ECB modes. Fixed a bug in GCM where AES block size was being used instead of authsize. Removed use of blkcipher_walk routines for scatterlist processing. Corner cases in the code prevent us from processing an entire scatterlist at a time and walking the buffers in block sized chunks turns out to be unecessary anyway. Fixed off-by-one error in saving off extra data in the sha code. Fixed accounting error for number of bytes processed in the sha code.

The DMA controller currently takes configuration information from information passed though dma_channel_request(), but it shouldn't. Using the API, the DMA channel should only be configured during a dma_slave_config() call. Cc: David S.

2013-05-14crypto: caam - FIX RNG init for RNG greater than equal to 4Ruchika Gupta
For SEC including a RNG block version >= 4, special initialization must occur before any descriptor that uses RNG block can be submitted. This initialization is required not only for SEC with version greater than 5.0, but for SEC with RNG version >=4. There may be a case where RNG has already been instantiated by u-boot or boot ROM code.In such SoCs, if RNG is initialized again SEC would returns "Instantiation error". Hence, the initialization status of RNG4 should be also checked before doing RNG init.

One of the larger platforms remaining is Samsung Exynos, and there are a bunch of supporting patches in this merge window for it. There was a patch in this branch to a early version of multiplatform conversion, but it ended up being reverted due to need of more bake time.

2013-04-25crypto: caam - fix job ring cleanup codeVakul Garg
The job ring init function creates a platform device for each job ring. While the job ring is shutdown, e.g. while caam module removal, its platform device was not being removed. This leads to failure while reinsertion and then removal of caam module second time. The following kernel crash dump appears when caam module is reinserted and then removed again. This patch fixes it. root@p4080ds:~# rmmod caam.ko Unable to handle kernel paging request for data at address 0x00000008 Faulting instruction address: 0xf94aca18 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=8 P4080 DS Modules linked in: caam(-) qoriq_dbg(O) [last unloaded: caam] NIP: f94aca18 LR: f94aca18 CTR: c029f950 REGS: eac47d60 TRAP: 0300 Tainted: G O (3.8.4-rt2) MSR: 00029002 <CE,EE,ME> CR: 22022484 XER: 20000000 DEAR: 00000008, ESR: 00000000 TASK = e49dfaf0[2110] 'rmmod' THREAD: eac46000 CPU: 1 GPR00: f94ad3f4 eac47e10 e49dfaf0 00000000 00000005 ea2ac210 ffffffff 00000000 GPR08: c286de68 e4977ce0 c029b1c0 00000001 c029f950 10029738 00000000 100e0000 GPR16: 00000000 10023d00 1000cbdc 1000cb8c 1000cbb8 00000000 c07dfecc 00000000 GPR24: c07e0000 00000000 1000cbd8 f94e0000 ffffffff 00000000 ea53cd40 00000000 NIP [f94aca18] caam_reset_hw_jr+0x18/0x1c0 [caam] LR [f94aca18] caam_reset_hw_jr+0x18/0x1c0 [caam] Call Trace: [eac47e10] [eac47e30] 0xeac47e30 (unreliable) [eac47e20] [f94ad3f4] caam_jr_shutdown+0x34/0x220 [caam] [eac47e60] [f94ac0e4] caam_remove+0x54/0xb0 [caam] [eac47e80] [c029fb38] __device_release_driver+0x68/0x120 [eac47e90] [c02a05c8] driver_detach+0xd8/0xe0 [eac47eb0] [c029f8e0] bus_remove_driver+0xa0/0x110 [eac47ed0] [c00768e4] sys_delete_module+0x144/0x270 [eac47f40] [c000e2f0] ret_from_syscall+0x0/0x3c Signed-off-by: Vakul Garg <vakul@freescale.com> Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Reviewed-by: Horia Geanta <horia.geanta@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
