The default cache operations for ARM64 were changed during 3.15. To use coherent operations a "dma-coherent" device tree property is required. If that property is not present in the device tree node then the non-coherent operations are assigned for the device. Add support to the ccp driver to assign the AXI DMA cache settings based on whether the "dma-coherent" property is present in the device node. If present, use settings that work with the caches. If not present, use settings that do not look at the caches. Signed-off-by:

The patch corrects the security strength of the HMAC-SHA1 DRBG to 128 bits. This strength defines the size of the seed required for the DRBG. Thus, the patch lowers the seeding requirement from 256 bits to 128 bits for HMAC-SHA1. Signed-off-by:

The current locking approach of the DRBG tries to keep the protected code paths very minimal. It is therefore possible that two threads query one DRBG instance at the same time. When thread A requests random numbers, a shadow copy of the DRBG state is created upon which the request for A is processed. After finishing the state for A's request is merged back into the DRBG state. If now thread B requests random numbers from the same DRBG after the request for thread A is received, but before A's shadow state is merged back, the random numbers for B will be identical to the ones for A. Please note that the time window is very small for this scenario. To prevent that there is even a theoretical chance for thread A and B having the same DRBG state, the current time stamp is provided as additional information string for each new request. The addition of the time stamp as additional information string implies that now all generate functions must be capable to process a linked list with additional information strings instead of a scalar.

When the DRBG is initialized, the core is looked up using the DRBG name. The name that can be used for the lookup is registered in cra_driver_name. The cra_name value contains stdrng. Thus, the lookup code must use crypto_tfm_alg_driver_name to obtain the precise DRBG name and select the correct DRBG. Signed-off-by:

The CTR DRBG requires the update function to be called twice when generating a random number. In both cases, update function must process the additional information string by using the DF function. As the DF produces the same result in both cases, we can save one invocation of the DF function when the first DF function result is reused. The result of the DF function is stored in the scratchpad storage. The patch ensures that the scratchpad is not cleared when we want to reuse the DF result. For achieving this, the CTR DRBG update function must know by whom and in which scenario it is called. This information is provided with the reseed parameter to the update function. Signed-off-by:

This patch removes the build-time test that ensures at least one RNG is set. Instead we will simply not build drbg if no options are set through Kconfig. This also fixes a typo in the name of the Kconfig option CRYTPO_DRBG (should be CRYPTO_DRBG). Signed-off-by: -

The DRBG-style linked list to manage input data that is fed into the cipher invocations is replaced with the kernel linked list implementation. The change is transparent to users of the interfaces offered by the DRBG. Therefore, no changes to the testmgr code is needed. Reported-by:

For the CTR DRBG, the drbg_state->scratchpad temp buffer (i.e. the memory location immediately before the drbg_state->tfm variable is the buffer that the BCC function operates on. BCC operates blockwise. Making the temp buffer drbg_statelen(drbg) in size is sufficient when the DRBG state length is a multiple of the block size. For AES192 this is not the case and the length for temp is insufficient (yes, that also means for such ciphers, the final output of all BCC rounds are truncated before used to update the state of the DRBG!!). The patch enlarges the temp buffer from drbg_statelen to drbg_statelen + drbg_blocklen to have sufficient space. Reported-by:

The interrupt handler in the ux500 crypto driver has an obviously incorrect way to access the data buffer, which for a while has caused this build warning: ../ux500/cryp/cryp_core.c: In function 'cryp_interrupt_handler': ../ux500/cryp/cryp_core.c:234:5: warning: passing argument 1 of '__fswab32' makes integer from pointer without a cast [enabled by default] writel_relaxed(ctx->indata, ^ In file included from ../include/linux/swab.h:4:0, from ../include/uapi/linux/byteorder/big_endian.h:12, from ../include/linux/byteorder/big_endian.h:4, from ../arch/arm/include/uapi/asm/byteorder.h:19, from ../include/asm-generic/bitops/le.h:5, from ../arch/arm/include/asm/bitops.h:340, from ../include/linux/bitops.h:33, from ../include/linux/kernel.h:10, from ../include/linux/clk.h:16, from ../drivers/crypto/ux500/cryp/cryp_core.c:12: ../include/uapi/linux/swab.h:57:119: note: expected '__u32' but argument is of type 'const u8 *' static inline __attribute_const__ __u32 __fswab32(__u32 val) There are at least two, possibly three problems here: a) when writing into the FIFO, we copy the pointer rather than the actual data we want to give to the hardware b) the data pointer is an array of 8-bit values, while the FIFO is 32-bit wide, so both the read and write access fail to do a proper type conversion c) This seems incorrect for big-endian kernels, on which we need to byte-swap any register access, but not normally FIFO accesses, at least the DMA case doesn't do it either. This converts the bogus loop to use the same readsl/writesl pair that we use for the two other modes (DMA and polling). This is more efficient and consistent, and probably correct for endianess. The bug has existed since the driver was first merged, and was probably never detected because nobody tried to use interrupt mode. It might make sense to backport this fix to stable kernels, depending on how the crypto maintainers feel about that.
