SS_ENCRYPTION is (0 << 7 = 0), so the test can never be true. Use a direct comparison to SS_ENCRYPTION instead. The same king of test is already done the same way in sun8i_ss_run_task(). Fixes: 359e893e ("crypto: sun8i-ss - rework handling of IV") Signed-off-by:

Mendocino and later platform don't use the platform feature mailbox for communication for I2C arbitration, they rely upon ringing a doorbell. Detect the platform by the device ID of the root port and choose the appropriate method. Link: https://lore.kernel.org/linux-i2c/20220916131854.687371-3-jsd@semihalf.com/Signed-off-by:

Currently the PSP semaphore communication base address is discovered by using an MSR that is not architecturally guaranteed for future platforms. Also the mailbox that is utilized for communication with the PSP may have other consumers in the kernel, so it's better to make all communication go through a single driver. Signed-off-by:

Add some test vectors for 128-bit cmac(camellia) as found in draft-kato-ipsec-camellia-cmac96and128-01 section 6.2. The document also shows vectors for camellia-cmac-96, and for VK with a length greater than 16, but I'm not sure how to express those in testmgr. This also leaves cts(cbc(camellia)) untested, but I can't seem to find any tests for that that I could put into testmgr. Signed-off-by:

Herbert Xu authored
This patch adds the helpers crypto_clone_ahash and crypto_clone_shash. They are the hash-specific counterparts of crypto_clone_tfm. This allows code paths that cannot otherwise allocate a hash tfm object to do so. Once a new tfm has been obtained its key could then be changed without impacting other users. Note that only algorithms that implement clone_tfm can be cloned. However, all keyless hashes can be cloned by simply reusing the tfm object. Signed-off-by:

This patch adds the helper crypto_clone_tfm. The purpose is to allocate a tfm object with GFP_ATOMIC. As we cannot sleep, the object has to be cloned from an existing tfm object. This allows code paths that cannot otherwise allocate a crypto_tfm object to do so. Once a new tfm has been obtained its key could then be changed without impacting other users. Signed-off-by:

Add a crypto_tfm_get interface to allow tfm objects to be shared. They can still be freed in the usual way. This should only be done with tfm objects with no keys. You must also not modify the tfm flags in any way once it becomes shared. Signed-off-by:

The crypt_ctl structure must be exactly 64 bytes long to work correctly, and it has to be a power-of-two size to allow turning the 64-bit division in crypt_phys2virt() into a shift operation, avoiding the link failure: ERROR: modpost: "__aeabi_uldivmod" [drivers/crypto/intel/ixp4xx/ixp4xx_crypto.ko] undefined! The failure now shows up because the driver is available for compile testing after the move, and a previous fix turned the more descriptive BUILD_BUG_ON() into a link error. Change the variably-sized dma_addr_t into the expected 'u32' type that is needed for the hardware, and reinstate the size check for all 32-bit architectures to simplify debugging if it hits again.

caam driver needs to be aware of OP-TEE f/w presence, since some things are done differently: 1. there is no access to controller's register page (note however that some registers are aliased in job rings' register pages) 2 Due to this, MCFGR[PS] cannot be read and driver assumes MCFGR[PS] = b'0 - engine using 32-bit address pointers. This is in sync with the fact that: -all i.MX SoCs currently use MCFGR[PS] = b'0 -only i.MX OP-TEE use cases don't allow access to controller register page Signed-off-by:
