| * crypto: caam/qi - simplify CGR allocation, freeingHoria Geantă2018-10-172-40/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CGRs (Congestion Groups) have to be freed by the same CPU that initialized them. This is why currently the driver takes special measures; however, using set_cpus_allowed_ptr() is incorrect - as reported by Sebastian. Instead of the generic solution of replacing set_cpus_allowed_ptr() with work_on_cpu_safe(), we use the qman_delete_cgr_safe() QBMan API instead of qman_delete_cgr() - which internally takes care of proper CGR deletion.

A set of dummy import/export functions were implemented in commit 9190b6fd5db9 ("crypto: mxs-dcp - Add empty hash export and import") but statesize is still zero and the driver fails to probe.

Since qat_alg_do_precomputes() is only called in the context of a setkey() operation, this should be safe.

| * | crypto: s5p-sss: Add aes-ctr supportChristoph Manszewski2018-09-281-5/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for aes counter(ctr) block cipher mode of operation for Exynos Hardware. In contrast to ecb and cbc modes, aes-ctr allows encyption/decryption for request sizes not being a multiple of 16(bytes). Hardware requires block sizes being a multiple of 16(bytes). In order to achieve this, copy request source and destination memory, and align it's size to 16. That way hardware processes additional bytes, that are omitted when copying the result back to its original destination. Tested on Odroid-U3 with Exynos 4412 CPU, kernel 4.19-rc2 with crypto run-time self test testmgr.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During PSP initialization, there is an attempt to update the SEV firmware by looking in /lib/firmware/amd/. Currently, sev.fw is the expected name of the firmware blob. This patch will allow for firmware filenames based on the family and model of the processor. Model specific firmware files are given highest priority. Followed by firmware for a subset of models. Lastly, failing the previous two options, fallback to looking for sev.fw.

Data transfers (crypto requests) are sent/received to/from CAAM crypto engine via Queue Interface (v2), this being similar to existing caam/qi. OTOH, configuration/setup (obtaining virtual queue IDs, authorization etc.) is done by sending commands to the MC f/w. Note that the CAAM accelerator included in DPAA2 platforms still has Job Rings. However, the driver being added does not handle access via this backend. Kconfig & Makefile are updated such that DPAA2-CAAM (a.k.a. "caam/qi2") driver does not depend on caam/jr or caam/qi backends - which rely on platform bus support (ctrl.c). Support for the following aead and authenc algorithms is also added in this patch: -aead: gcm(aes) rfc4106(gcm(aes)) rfc4543(gcm(aes)) -authenc: authenc(hmac({md5,sha*}),cbc({aes,des,des3_ede})) echainiv(authenc(hmac({md5,sha*}),cbc({aes,des,des3_ede}))) authenc(hmac({md5,sha*}),rfc3686(ctr(aes)) seqiv(authenc(hmac({md5,sha*}),rfc3686(ctr(aes))) Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
