crypto: caam - add allocation failure handling in SPRINTFCAT macro

2014-04-28T10:17:18+00:00

GFP_ATOMIC memory allocation could fail. In this case, avoid NULL pointer dereference and notify user. Cc: # 3.2+ Cc: Kim Phillips Signed-off-by: Horia Geanta Signed-off-by: Herbert Xu

crypto: caam - add missing key_dma unmap

2014-03-21T13:54:28+00:00

(struct caam_ctx) ctx->key_dma needs to be unmapped when context is cleaned up. Signed-off-by: Horia Geanta Signed-off-by: Herbert Xu

crypto: caam - add support for aead null encryption

2014-03-21T13:54:27+00:00

Add support for the following combinations: -encryption: null -authentication: md5, sha* (1, 224, 256, 384, 512) Signed-off-by: Tudor Ambarus Signed-off-by: Horia Geanta Signed-off-by: Herbert Xu

crypto: caam - remove error propagation handling

2014-03-21T13:54:24+00:00

Commit 61bb86bba169507a5f223b94b9176c32c84b4721 ("crypto: caam - set descriptor sharing type to SERIAL") changed the descriptor sharing mode from SHARE_WAIT to SHARE_SERIAL. All descriptor commands that handle the "ok to share" and "error propagation" settings should also go away, since they have no meaning for SHARE_SERIAL.

crypto: caam - Fix first parameter to caam_init_rng

2014-03-21T13:32:54+00:00

Found by the kbuild test robot, the first argument to caam_init_rng has a spurious ampersand. Reported-by: kbuild test robot Signed-off-by: Herbert Xu

crypto: caam - Dynamic memory allocation for caam_rng_ctx object

2014-03-10T12:17:12+00:00

This patch allocates memory from DMAable region to the caam_rng_ctx object, earlier it had been statically allocated which resulted in errorneous behaviour on inserting the caamrng module at the runtime. Signed-off-by: Nitesh Lal Acked-by: Ruchika Gupta Signed-off-by: Herbert Xu

crypto: caam - writel() arguments are swapped

2014-02-26T21:56:59+00:00

My guess is that this little endian configuration is never found in real life, but if it were then the writel() arguments are in the wrong order so the driver would crash immediately. Signed-off-by: Dan Carpenter Acked-by: Kim Phillips Signed-off-by: Herbert Xu

crypto: caam - fix ERA retrieval function

2014-02-09T01:59:27+00:00

SEC ERA has to be retrieved by reading the "fsl,sec-era" property from the device tree. This property is updated/filled in by u-boot. Signed-off-by: Alex Porosanu Reviewed-by: Horia Geanta Signed-off-by: Herbert Xu

crypto: caam - Fix job ring discovery in controller driver

2014-02-09T01:59:13+00:00

The SEC Controller driver creates platform devices for it's child job ring nodes. Currently the driver uses for_each_compatible routine which traverses the whole device tree to create the job rings for the platform device. The patch changes this to search for the compatible property of job ring only in the child nodes i.e., the job rings are created as per the number of children associated with the crypto node.

crypto: caam - simplify and harden key parsing

2013-12-20T12:06:27+00:00

Use the common helper function crypto_authenc_extractkeys() for key parsing. Also fix the key buffer overflow condition: use split key pad length instead of authentication key length. Signed-off-by: Horia Geanta Signed-off-by: Herbert Xu
