crypto: caam - add SPDX license identifier to all files

2018-10-17T06:16:18Z

Previously, a tree-wide change added SPDX license identifiers to files lacking licensing information: b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") To be consistent update the rest of the files: -files with license specified by means of MODULE_LICENSE() -files with complete license text -Kconfig Signed-off-by: Horia Geantă Signed-off-by: Herbert Xu

crypto: caam/qi2 - add CONFIG_NETDEVICES dependency

2018-10-05T02:22:48Z

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.

crypto: caam/qi2 - add skcipher algorithms

crypto: caam/qi2 - add DPAA2-CAAM driver

2018-09-21T05:24:51Z

Add CAAM driver that works using the DPSECI backend, i.e. manages DPSECI DPAA2 objects sitting on the Management Complex (MC) fsl-mc bus. 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 Signed-off-by: Herbert Xu

crypto: caam - fix LS1021A support on ARMv7 multiplatform kernel

2017-09-20T09:42:42Z

When built using multi_v7_defconfig, driver does not work on LS1021A: [...] caam 1700000.crypto: can't identify CAAM ipg clk: -2 caam: probe of 1700000.crypto failed with error -2 [...] It turns out we have to detect at runtime whether driver is running on an i.MX platform or not.

crypto: caam/qi - add ablkcipher and authenc algorithms

2017-03-24T14:02:59Z

Add support to submit ablkcipher and authenc algorithms via the QI backend: -ablkcipher: cbc({aes,des,des3_ede}) ctr(aes), rfc3686(ctr(aes)) xts(aes) -authenc: authenc(hmac(md5),cbc({aes,des,des3_ede})) authenc(hmac(sha*),cbc({aes,des,des3_ede})) caam/qi being a new driver, let's wait some time to settle down without interfering with existing caam/jr driver. Accordingly, for now all caam/qi algorithms (caamalg_qi module) are marked to be of lower priority than caam/jr ones (caamalg module).

crypto: caam - make aamalg_desc a proper module

2016-12-01T13:06:40Z

The drivers/crypto/caam/ directory is entered during build only for building modules when CONFIG_CRYPTO_DEV_FSL_CAAM=m, but CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_DESC is defined as a 'bool' symbol, meaning that caamalg_desc.c is always compiled into built-in code, or not at all, leading to a link failure: ERROR: "cnstr_shdsc_xts_ablkcipher_decap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_xts_ablkcipher_encap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_aead_givencap" [drivers/crypto/caam/caamalg.ko] undefined!

Making caamalg_desc itself a loadable module fixes this configuration by ensuring the driver gets built. Aside from making the symbol 'tristate', I'm adding appropriate module metadata here.
