Few storage technology such is EMMC, UFS, and NVMe support RPMB
hardware partition with common protocol and frame layout.
The RPMB partition cannot be accessed via standard block layer, but
by a set of specific commands: WRITE, READ, GET_WRITE_COUNTER, and
PROGRAM_KEY.
Such a partition provides authenticated and replay protected access,
hence suitable as a secure storage.
A storage device registers its RPMB hardware (emmc) partition or
RPMB W-LUN (ufs) with the RPMB layer providing an implementation for
send_rpmb_req() handler.
Tere is as well simulation platform device. This is handy as an RPMB
key can be programmed only once at storage device lifetime.
ThePMB layer aims to provide in-kernel API for Trusted Execution
Environment (TEE) devices that are capable to securely compute block
frame signature. In case a TEE device wish to store a replay protected
data, it creates an RPMB frame with requested data and computes HMAC of
the frame, then it requests the storage device via RPMB layer to store
the data.
A TEE driver can claim rpmb interface, for example,
via class_interface_register ().
A parallel user space API is provided via /dev/rpmbX character
device with a single IOCTL command similar to the one provided by
mmc/ioctl. h
There is a sample tool under tools/rpmb/ directory that exercises
this interface.

Add attribute type that displays underlay storage type technology
EMMC, UFS, and attribute id, that displays underlay storage device id.
For EMMC this would be content of CID and for UFS serial number from
the device descriptor

This is simple platform device for used for testing
rpmb subystem.
The module currently suppot two configuration options
1.max_wr_blks: for specifying max blocks that can be written
in a single command and.
2. daunits: used to set storage capacity in 128K units.

Register UFS RPMB LUN with the RPMB subsystem and provide
implementation for the RPMB access operations. RPMB partition is
accessed via a sequence of security protocol in and security protocol
out commands with UFS specific parameters. This multi step process is
abstracted into 4 basic RPMB commands.

I have a UFS device emulator that has the RPMB capability. What are the expected
good results for me to validate?
Thanks.

Hi Joao, thanks for that. I'm attaching an archive with few basic

You should run the program key first (program-key.sh), just don't do it
on a real device it's one in life time operation.
Thanks
Tomas

Hi Joao, thanks for that. I'm attaching an archive with few basic
samples via user space interface.
You should run the program key first (program-key.sh), just don't do it
on a real device it's one in life time operation.
Thanks
Tomas

I have tested your patch set the following way:
Patches applied:
- Got 4.7-queue from the SCSI repo
- Applied the patch set for DW UFS support
- Applied your patch set for RPMB support
Platform (UFS IP Prototyping Kit):
- CPU: ARC CPU 32-bit
- UFS 2.0 Core running in FPGA
Results:
Kernel Build without RPMB configured: OK
Kernel Build with RPMB configured: OK
UFS Device partitions shown in UFS Host without RPMB configured: Yes
UFS Device partitions shown in UFS Host with RPMB configured: Yes
I would like to run more verifications regarding RPMB. Could you tell me what is
the procedure you suggest?
Thanks,
Joao

Managed to cross-compile to ARC and execute your test app in my platform. I made
it in Buildroot, so I have the patches to enable the tool cross-compilation if
necessary in the future.
The tool execution gives no errors, but also no info. I suggest you had success
info and maybe some statistic (e.g. bytes read or written).

Sounds like fun :)
I've just tried to follow the standard under tools, though this it's not something really generic which was surpising to me as this is in the kernel tree.

It did have some verbose print outs on both ends, but I've cleaned it out. It was meant to be an example rather than unit testing tool, but we can repurpose it.

Just to put that straight, those are issues in the testing environment
not in the patches.
