crypto: caam - enable prediction resistance in HRWNG

2020-03-30T00:50:50Z

Instantiate CAAM RNG with prediction resistance enabled to improve its quality (with PR on DRNG is forced to reseed from TRNG every time random data is generated). Management Complex firmware with version lower than 10.20.0 doesn't provide prediction resistance support. Consider this and only instantiate rng when mc f/w version is lower.

crypto: caam - support crypto_engine framework for SKCIPHER algorithms

2020-02-22T01:25:47Z

Integrate crypto_engine into CAAM, to make use of the engine queue. Add support for SKCIPHER algorithms. This is intended to be used for CAAM backlogging support. The requests, with backlog flag (e.g. from dm-crypt) will be listed into crypto-engine queue and processed by CAAM when free. This changes the return codes for enqueuing a request: -EINPROGRESS if OK, -EBUSY if request is backlogged (via crypto-engine), -ENOSPC if the queue is full, -EIO if it cannot map the caller's descriptor. The requests, with backlog flag, will be listed into crypto-engine queue and processed by CAAM when free. Only the backlog request are sent to crypto-engine since the others can be handled by CAAM, if free, especially since JR has up to 1024 entries (more than the 10 entries from crypto-engine).

crypto: skcipher - rename the crypto_blkcipher module and kconfig option

2019-11-01T05:42:47Z

Now that the blkcipher algorithm type has been removed in favor of skcipher, rename the crypto_blkcipher kernel module to crypto_skcipher, and rename the config options accordingly: CONFIG_CRYPTO_BLKCIPHER => CONFIG_CRYPTO_SKCIPHER CONFIG_CRYPTO_BLKCIPHER2 => CONFIG_CRYPTO_SKCIPHER2 Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: des - split off DES library from generic DES cipher driver

2019-08-22T04:57:33Z

Another one for the cipher museum: split off DES core processing into a separate module so other drivers (mostly for crypto accelerators) can reuse the code without pulling in the generic DES cipher itself. This will also permit the cipher interface to be made private to the crypto API itself once we move the only user in the kernel (CIFS) to this library interface.

crypto: caam - check key length

Check key length to solve the extra tests that expect -EINVAL to be returned when the key size is not valid. Validated AES keylen for skcipher, ahash and aead. Signed-off-by: Iuliana Prodan Reviewed-by: Horia Geanta Signed-off-by: Herbert Xu

crypto: caam - convert top level drivers to libraries

2019-05-23T06:01:03Z

Currently we allow top level code, i.e. that which sits between the low level (HW-specific) drivers and crypto API, to be built as several drivers: caamalg, caamhash, caam_pkc, caamrng, caamalg_qi. There is no advantage in this, more it interferes with adding support for deferred probing (there are no corresponding devices and thus no bus). Convert these drivers and call init() / exit() manually at the right time. Move algorithms initialization at JR probe / remove time: -the first probed JR registers the crypto algs -the last removed JR unregisters the crypto algs Note: caam_qi_init() is called before JR platform devices creation (of_populate_bus()), such that QI interface is initialized when the caam/qi algorithms are registered in the JR driver (by calling caam_qi_algapi_init(). While here, fix the Kconfig entries under CRYPTO_DEV_FSL_CAAM_JR to be aligned. Signed-off-by: Horia Geantă Signed-off-by: Herbert Xu

crypto: caam/qi2 - add CONFIG_NETDEVICES dependency

This driver implements a (part of a) network driver, and fails to build if we have turned off networking support: drivers/crypto/caam/caamalg_qi2.o: In function `dpaa2_caam_fqdan_cb': caamalg_qi2.c:(.text+0x577c): undefined reference to `napi_schedule_prep' caamalg_qi2.c:(.text+0x578c): undefined reference to `__napi_schedule_irqoff' drivers/crypto/caam/caamalg_qi2.o: In function `dpaa2_dpseci_poll': caamalg_qi2.c:(.text+0x59b8): undefined reference to `napi_complete_done' drivers/crypto/caam/caamalg_qi2.o: In function `dpaa2_caam_remove': caamalg_qi2.c:(.text.unlikely+0x4e0): undefined reference to `napi_disable' caamalg_qi2.c:(.text.unlikely+0x4e8): undefined reference to `netif_napi_del' drivers/crypto/caam/caamalg_qi2.o: In function `dpaa2_dpseci_setup': caamalg_qi2.c:(.text.unlikely+0xc98): undefined reference to `netif_napi_add' From what I can tell, CONFIG_NETDEVICES is the correct dependency here, and adding it fixes the randconfig failures.
