crypto: Use zeroing memory allocator instead of allocator/memset

2018-01-12T12:02:56+00:00

Use dma_zalloc_coherent for allocating zeroed memory and remove unnecessary memset function. Done using Coccinelle. Generated-by: scripts/coccinelle/api/alloc/kzalloc-simple.cocci 0-day tested with no failures. Signed-off-by: Himanshu Jha Signed-off-by: Herbert Xu

crypto: crypto4xx - perform aead icv check in the driver

2018-01-05T07:43:05+00:00

The ccm-aes-ppc4xx now fails one of testmgr's expected failure test cases as such: |decryption failed on test 10 for ccm-aes-ppc4xx: |ret was 0, |expected -EBADMSG It doesn't look like the hardware sets the authentication failure flag. The original vendor source from which this was ported does not have any special code or notes about why this would happen or if there are any WAs. Hence, this patch converts the aead_done callback handler to perform the icv check in the driver. And this fixes the false negative and the ccm-aes-ppc4xx passes the selftests once again. |name : ccm(aes) |driver : ccm-aes-ppc4xx |module : crypto4xx |priority : 300 |refcnt : 1 |selftest : passed |internal : no |type : aead |async : yes |blocksize : 1 |ivsize : 16 |maxauthsize : 16 |geniv : Signed-off-by: Christian Lamparter Signed-off-by: Herbert Xu

crypto: crypto4xx - kill MODULE_NAME

KBUILD_MODNAME provides the same value. Signed-off-by: Christian Lamparter Signed-off-by: Herbert Xu

crypto: crypto4xx - fix missing irq devname

2018-01-05T07:43:04+00:00

crypto4xx_device's name variable is not set to anything. The common devname for request_irq seems to be the module name. This will fix the seemingly anonymous interrupt entry in /proc/interrupts for crypto4xx. Signed-off-by: Christian Lamparter Signed-off-by: Herbert Xu

crypto: crypto4xx - support Revision B parts

2018-01-05T07:43:03+00:00

This patch adds support for the crypto4xx RevB cores found in the 460EX, 460SX and later cores (like the APM821xx). Without this patch, the crypto4xx driver will not be able to process any offloaded requests and simply hang indefinitely. Signed-off-by: Christian Lamparter Signed-off-by: Herbert Xu

crypto: crypto4xx - shuffle iomap in front of request_irq

2018-01-05T07:43:02+00:00

It is possible to avoid the ce_base null pointer check in the drivers' interrupt handler routine "crypto4xx_ce_interrupt_handler()" by simply doing the iomap in front of the IRQ registration. This way, the ce_base will always be valid in the handler and a branch in an critical path can be avoided. Signed-off-by: Christian Lamparter Signed-off-by: Herbert Xu

crypto: crypto4xx - add aes-gcm support

crypto: crypto4xx - prepare for AEAD support

This patch enhances existing interfaces and functions to support AEAD ciphers in the next patches. Signed-off-by: Christian Lamparter Signed-off-by: Herbert Xu

crypto: crypto4xx - simplify sa and state context acquisition

2017-10-12T14:55:18+00:00

Thanks to the big overhaul of crypto4xx_build_pd(), the request-local sa_in, sa_out and state_record allocation can be simplified. There's no need to setup any dma coherent memory anymore and much of the support code can be removed. Signed-off-by: Christian Lamparter Signed-off-by: Herbert Xu
