2014-08-25crypto: drbg - remove configuration of fixed valuesStephan Mueller2-46/+6
SP800-90A mandates several hard-coded values. The old drbg_cores allows the setting of these values per DRBG implementation. However, due to the hard requirement of SP800-90A, these values are now returned globally for each DRBG. The ability to set such values per DRBG is therefore removed.

2014-08-25crypto: drbg - remove unnecessary sanity checksStephan Mueller1-9/+0
The drbg_make_shadow function contains sanity checks which are not needed as the function is invoked at times where it is ensured that the checked-for variables are available. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2014-08-25crypto: drbg - use kmalloc instead of kzalloc for V and CStephan Mueller1-3/+8
When allocating V, C, the zeroization is only needed when allocating a new instance of the DRBG, i.e. when performing an initial seeding. For all other allocations, the memcpy implemented in drbg_copy_drbg ensures that the memory is filled with the correct information.

2014-08-25crypto: drbg - kzfree does not need a check for NULL pointerStephan Mueller1-12/+6
The kzfree function already performs the NULL pointer check. Therefore, the DRBG code does not need to implement such check. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2014-08-25crypto: drbg - replace int2byte with cpu_to_beStephan Mueller1-16/+18
The DRBG requires the conversion of an integer into a string representation of that integer. The previous implementation converted the given integer byte-wise. However, the kernel offers the cpu_to_be function which already re-arranges the memory representation of an integer such that it applies when interpreting the same memory as character string. The change therefore uses an integer-cast / union of the target character array together with the cpu_to_be function to convert an integer into its string representation. Tests show that the Hash and CTR DRBG implementations (the HMAC DRBG does not require such conversion) is about 10% faster (or requires less computing power, respectively).

2014-08-25crypto: caam - remove duplicated sg copy functionsCristian Stoica2-62/+14
Replace equivalent (and partially incorrect) scatter-gather functions with ones from crypto-API. The replacement is motivated by page-faults in sg_copy_part triggered by successive calls to crypto_hash_update. The following fault appears after calling crypto_ahash_update twice, first with 13 and then with 285 bytes: Unable to handle kernel paging request for data at address 0x00000008 Faulting instruction address: 0xf9bf9a8c Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=8 CoreNet Generic Modules linked in: tcrypt(+) caamhash caam_jr caam tls CPU: 6 PID: 1497 Comm: cryptomgr_test Not tainted 3.12.19-rt30-QorIQ-SDK-V1.6+g9fda9f2 #75 task: e9308530 ti: e700e000 task.ti: e700e000 NIP: f9bf9a8c LR: f9bfcf28 CTR: c0019ea0 REGS: e700fb80 TRAP: 0300 Not tainted (3.12.19-rt30-QorIQ-SDK-V1.6+g9fda9f2) MSR: 00029002 <CE,EE,ME> CR: 44f92024 XER: 20000000 DEAR: 00000008, ESR: 00000000 GPR00: f9bfcf28 e700fc30 e9308530 e70b1e55 00000000 ffffffdd e70b1e54 0bebf888 GPR08: 902c7ef5 c0e771e2 00000002 00000888 c0019ea0 00000000 00000000 c07a4154 GPR16: c08d0000 e91a8f9c 00000001 e98fb400 00000100 e9c83028 e70b1e08 e70b1d48 GPR24: e992ce10 e70b1dc8 f9bfe4f4 e70b1e55 ffffffdd e70b1ce0 00000000 00000000 NIP [f9bf9a8c] sg_copy+0x1c/0x100 [caamhash] LR [f9bfcf28] ahash_update_no_ctx+0x628/0x660 [caamhash] Call Trace: [e700fc30] [f9bf9c50] sg_copy_part+0xe0/0x160 [caamhash] (unreliable) [e700fc50] [f9bfcf28] ahash_update_no_ctx+0x628/0x660 [caamhash] [e700fcb0] [f954e19c] crypto_tls_genicv+0x13c/0x300 [tls] [e700fd10] [f954e65c] crypto_tls_encrypt+0x5c/0x260 [tls] [e700fd40] [c02250ec] __test_aead.constprop.9+0x2bc/0xb70 [e700fe40] [c02259f0] alg_test_aead+0x50/0xc0 [e700fe60] [c02241e4] alg_test+0x114/0x2e0 [e700fee0] [c022276c] cryptomgr_test+0x4c/0x60 [e700fef0] [c004f658] kthread+0x98/0xa0 [e700ff40] [c000fd04] ret_from_kernel_thread+0x5c/0x64 Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2014-08-25crypto: caam - enable raw data instead of von Neumann dataAlex Porosanu2-1/+20
The sampling of the oscillator can be done in multiple modes for generating the entropy value. By default, this is set to von Neumann. This patch changes the sampling to raw data, since it has been discovered that the generated entropy has a better 'quality'.

2014-08-25crypto: caam - change starting entropy delay valueAlex Porosanu2-1/+10
The entropy delay (the length in system clocks of each entropy sample) for the RNG4 block of CAAM is dependent on the frequency of the SoC. By elaborate methods, it has been determined that a good starting value for all platforms integrating the CAAM IP is 3200. Using a higher value has additional benefit of speeding up the process of instantiating the RNG, since the entropy delay will be increased and instantiation of the RNG state handles will be reattempted by the driver. If the starting value is low, for certain platforms, this can lead to a quite lengthy process. This patch changes the starting value of the length of the entropy sample to 3200 system clocks. In addition to this change, the attempted entropy delay values are now printed on the console upon initialization of the RNG block. While here, a safeguard for yielding the processor was added for ensuring that in very adverse cases, the CPU isn't hogged by the instantiation loop.

2014-08-25crypto: caam - disable RNG oscillator maximum frequency checkAlex Porosanu2-2/+3
The rtfrqmax & rtfrqmin set the bounds of the expected frequency of the oscillator, when SEC runs at its maximum frequency. For certain platforms (f.i. T2080), the oscillator is very fast and thus if the SEC runs at a lower than normal frequency, the ring oscillator is incorrectly detected as being out of bounds. This patch effectively disables the maximum frequency check, by setting a high enough maximum allowable frequency for the oscillator. The reasoning behind this is that usually a broken oscillator will run too slow (i.e. not run at all) rather than run too fast.

2014-08-25crypto: sha-mb - multibuffer crypto infrastructureTim Chen5-0/+857
This patch introduces the multi-buffer crypto daemon which is responsible for submitting crypto jobs in a work queue to the responsible multi-buffer crypto algorithm. The idea of the multi-buffer algorihtm is to put data streams from multiple jobs in a wide (AVX2) register and then take advantage of SIMD instructions to do crypto computation on several buffers simultaneously. The multi-buffer crypto daemon is also responsbile for flushing the remaining buffers to complete the computation if no new buffers arrive for a while.

2014-08-16thinkpad_acpi: Mark volume_alsa_control_{vol,mute} as __initdataMathias Krause1-2/+2
Mark volume_alsa_control_vol and volume_alsa_control_mute as __initdata, as snd_ctl_new1() will copy the relevant parts, so there is no need to keep the master copies around after initialization.

2014-08-16fujitsu-laptop: Mark fujitsu_dmi_table[] DMI table as __initconstMathias Krause1-5/+5
The DMI table is only ever used during initialization. Mark it as __initconst so its memory can be released afterwards -- roughly 1.5 kB. In turn, the callback functions can be marked with __init, too.

2014-08-16hp-wmi: Add missing __init annotations to initialization codeMathias Krause1-3/+3
These functions are only called from other initialization routines, so can be marked __init, too. Signed-off-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
