OpenCrypto: Convert sessions to opaque handles instead of integers

2018-07-18T00:56:25Z

Track session objects in the framework, and pass handles between the framework (OCF), consumers, and drivers. Avoid redundancy and complexity in individual drivers by allocating session memory in the framework and providing it to drivers in ::newsession(). Session handles are no longer integers with information encoded in various high bits. Use of the CRYPTO_SESID2FOO() macros should be replaced with the appropriate crypto_ses2foo() function on the opaque session handle. Convert OCF drivers (in particular, cryptosoft, as well as myriad others) to the opaque handle interface. Discard existing session tracking as much as possible (quick pass). There may be additional code ripe for deletion. Convert OCF consumers (ipsec, geom_eli, krb5, cryptodev) to handle-style interface. The conversion is largely mechnical. The change is documented in crypto.9. Inspired by https://lists.freebsd.org/pipermail/freebsd-arch/2018-January/018835.html . No objection from: ae (ipsec portion) Reported by: jhb

Remove "HMAC" from _HMAC_BLOCK_LEN macro names

2018-07-09T07:21:37Z

The block size is a property of the underlying hash algorithm, and has nothing to do with the HMAC construction. No functional change.

Enable cesa driver to work with Linux DT binding

2018-04-09T23:36:52Z

Linux device tree binding, whose usage is obligatory, comprises faulty representation of Marvell cryptographic engine (CESA) - two engines are artificially gathered into single DT node, in order to avoid certain SW limitation. This patch improves the cesa driver to support above binding, depending on compatible string, which helps to ensure backward compatibility.

SPDX: fix wrong license ID tag in dev/cesa.

sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Enable proper configuration of CESA MBUS windows

2017-05-19T08:19:39Z

For all Marvell devices, MBUS windows configuration is done in a common place. Only CESA was an exception, so move its related code from driver to mv_common.c. This way it uses same proper DRAM information, same as all other interfaces instead of parsing DT /memory node directly.

Remove remaining ifdefs from CESA header

2017-02-02T06:07:39Z

Commit r312743 ("Use SoC ID - based detection in CESA") resulted in build failing for Marvell armv5 platforms, which don't support the newer version of CESA controller. This patch provides a fix by removing ifdefs around bitfields' definitions, so that they are known to all platforms. Submitted by: Marcin Wojtas Obtained from: Semihalf Sponsored by: Stormshield

Fix SHA256 usage on older CESA versions

2017-01-25T10:25:59Z

Adding SHA256 support to Marvell crypto driver resulted in regression for older SoC's, not capable of handling this mode in hardware. Submitted by: Emeric Poupon Obtained from: Stormshield Sponsored by: Stormshield Reviewed by: zbb Differential revision: https://reviews.freebsd.org/D9215

Use SoC ID - based detection in CESA

2017-01-25T10:22:07Z

This commit introduces following changes in order to get rid of ifdef's from all around the driver. * Introduce sc_soc_id field in cesa_softc structure - this value is obtained in cesa_attach() anyway, so make use of it. * Replace ifdefs with SoC ID checks. * Perform PM control status only for relevant SoC's.
