crypto: ccp - Fix double add when creating new DMA command

2017-02-14T23:25:33Z

commit e5da5c5667381d2772374ee6a2967b3576c9483d upstream. Eliminate a double-add by creating a new list to manage command descriptors when created; move the descriptor to the pending list when the command is submitted.

crypto: ccp - Fix DMA operations when IOMMU is enabled

2017-02-14T23:25:33Z

commit 500c0106e638e08c2c661c305ed57d6b67e10908 upstream. An I/O page fault occurs when the IOMMU is enabled on a system that supports the v5 CCP. DMA operations use a Request ID value that does not match what is expected by the IOMMU, resulting in the I/O page fault. Setting the Request ID value to 0 corrects this issue.

crypto: qat - zero esram only for DH85x devices

2017-02-14T23:25:33Z

commit 685ce0626840e2673fe64ea8807684f7324fec5f upstream. Zero embedded ram in DH85x devices. This is not needed for newer generations as it is done by HW. Signed-off-by: Giovanni Cabiddu Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: qat - fix bar discovery for c62x

2017-02-14T23:25:33Z

commit 3484ecbe0e9deb94afb0b9b6172d77e98eb72b94 upstream. Some accelerators of the c62x series have only two bars. This patch skips BAR0 if the accelerator does not have it. Signed-off-by: Giovanni Cabiddu Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: chcr - Check device is allocated before use

2017-02-14T23:25:32Z

crypto: caam - fix AEAD givenc descriptors

2017-01-06T09:40:13Z

commit d128af17876d79b87edf048303f98b35f6a53dbc upstream. The AEAD givenc descriptor relies on moving the IV through the output FIFO and then back to the CTX2 for authentication. The SEQ FIFO STORE could be scheduled before the data can be read from OFIFO, especially since the SEQ FIFO LOAD needs to wait for the SEQ FIFO LOAD SKIP to finish first. The SKIP takes more time when the input is SG than when it's a contiguous buffer. If the SEQ FIFO LOAD is not scheduled before the STORE, the DECO will hang waiting for data to be available in the OFIFO so it can be transferred to C2. In order to overcome this, first force transfer of IV to C2 by starting the "cryptlen" transfer first and then starting to store data from OFIFO to the output buffer.

crypto: caam - fix pointer size for AArch64 boot loader, AArch32 kernel

2016-12-07T11:55:17Z

Start with a clean slate before dealing with bit 16 (pointer size) of Master Configuration Register. This fixes the case of AArch64 boot loader + AArch32 kernel, when the boot loader might set MCFGR[PS] and kernel would fail to clear it.

crypto: marvell - Don't corrupt state of an STD req for re-stepped ahash

2016-12-07T11:55:17Z

mv_cesa_hash_std_step() copies the creq->state into the SRAM at each step, but this is only required on the first one. By doing that, we overwrite the engine state, and get erroneous results when the crypto request is split in several chunks to fit in the internal SRAM. This commit changes the function to copy the state only on the first step. Fixes: commit 2786cee8e50b ("crypto: marvell - Move SRAM I/O op...")
