crypto: ccree - fix PM race condition

2020-02-11T12:35:22+00:00

commit 15fd2566bf54ee4d4781d8f170acfc9472a1541f upstream. The PM code was racy, possibly causing the driver to submit requests to a powered down device. Fix the race and while at it simplify the PM code.

crypto: ccree - drop legacy ivgen support

2019-07-26T04:51:55+00:00

ccree had a mechanism for IV generation which was not compatible with the Linux seqiv or echainiv iv generator and was never used in any of the upstream versions so drop all the code implementing it. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - add HW engine config check

2019-06-27T06:28:00+00:00

Add check to verify the stated device tree HW configuration matches the HW. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - check that cryptocell reset completed

2019-06-27T06:28:00+00:00

In case of driver probe and pm resume we need to check that the cryptocell hardware reset cycle is completed. during the reset cycle that Cryptocell provide read only access to the APB interface which allows to verify through the CC registers that the reset is completed. Until reset completion we assume that any write/crypto operation is blocked. Signed-off-by: Ofir Drang Signed-off-by: Herbert Xu

crypto: ccree - don't map AEAD key and IV on stack

2019-04-25T07:38:16+00:00

The AEAD authenc key and IVs might be passed to us on stack. Copy it to a slab buffer before mapping to gurantee proper DMA mapping. Signed-off-by: Gilad Ben-Yossef Cc: stable@vger.kernel.org # v4.19+ Signed-off-by: Herbert Xu

crypto: ccree - simplify fragment ICV detection

2019-04-25T07:38:15+00:00

The code detecting whether the ICV is fragmented was overly complex and limited the number of fragments an ICV may be comprised of with no reason in the current code, casuing the new testmgr tests to fail. This patch removes this legacy limitation and greatly simplifies the code. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - copyright header update

2019-04-25T07:38:14+00:00

This sacrificial copyright header update is offered to the legal department as atonement for any changes made in this driver files in the course of the current year which have not been duly recorded as such. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - add CPP completion handling

2019-04-25T07:38:13+00:00

Add the logic needed to track and report CPP operation rejection. The new logic will be used by the CPP feature introduced later. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - add support for sec disabled mode

2019-04-25T07:38:13+00:00

Add support for the Security Disabled mode under which only pure cryptographic functionality is enabled and protected keys services are unavailable. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - remove legacy leftover

Remove legacy code no longer in use. Signed-off-by: Hadar Gat Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu
