git://git.linaro.org/people/jens.wiklander/linux-tee into arm/drivers Enable multi-stage OP-TEE bus enumeration Probes drivers on the OP-TEE bus in two steps. First for drivers which do not depend on tee-supplicant. After tee-supplicant has been started probe the devices which do depend on tee-supplicant. Also introduces driver which uses an OP-TEE based fTPM Trusted Application depends on tee-supplicant NV RAM implementation based on RPMB secure storage. * tag 'optee-bus-for-v5.9' of git://git.linaro.org/people/jens.wiklander/linux-tee: tpm_ftpm_tee: register driver on TEE bus optee: enable support for multi-stage bus enumeration optee: use uuid for sysfs driver entry Link: https://lore.kernel.org/r/20200710085230.GA1312913@jade Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2020-07-10optee: enable support for multi-stage bus enumerationMaxim Uvarov3-22/+44
Some drivers (like ftpm) can operate only after tee-supplicant runs because of tee-supplicant provides things like storage services (rpmb, shm).  This patch splits probe of non tee-supplicant dependable drivers to the early stage, and after tee-supplicant run probe other drivers.

2020-07-10optee: use uuid for sysfs driver entryMaxim Uvarov1-3/+6
With the evolving use-cases for TEE bus, now it's required to support multi-stage enumeration process. But using a simple index doesn't suffice this requirement and instead leads to duplicate sysfs entries. So instead switch to use more informative device UUID for sysfs entry like: /sys/bus/tee/devices/optee-ta-<uuid> Signed-off-by: Maxim Uvarov <maxim.uvarov@linaro.org> Reviewed-by: Sumit Garg <sumit.garg@linaro.org> Reviewed-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> Tested-by: Sumit Garg <sumit.garg@linaro.org> Signed-off-by: Jens Wiklander <jens.wiklander@linaro.org>

2020-05-11tee: add support for session's client UUID generationVesa Jääskeläinen2-0/+153
TEE Client API defines that from user space only information needed for specified login operations is group identifier for group based logins. REE kernel is expected to formulate trustworthy client UUID and pass that to TEE environment. REE kernel is required to verify that provided group identifier for group based logins matches calling processes group memberships. TEE specification only defines that the information passed from REE environment to TEE environment is encoded into on UUID. In order to guarantee trustworthiness of client UUID user space is not allowed to freely pass client UUID. UUIDv5 form is used encode variable amount of information needed for different login types.

This will permit us to use the generic device property layer for parsing additional properties, regardless of whether DT or ACPI is being used.

2019-11-15tee: optee: fix device enumeration error handlingJens Wiklander1-8/+12
Prior to this patch in optee_probe() when optee_enumerate_devices() was called the struct optee was fully initialized. If optee_enumerate_devices() returns an error optee_probe() is supposed to clean up and free the struct optee completely, but will at this late stage need to call optee_remove() instead. This isn't done and thus freeing the struct optee prematurely. With this patch the call to optee_enumerate_devices() is done after optee_probe() has returned successfully and in case optee_enumerate_devices() fails everything is cleaned up with a call to optee_remove().

2019-10-23compat_ioctl: move more drivers to compat_ptr_ioctlArnd Bergmann1-1/+1
The .ioctl and .compat_ioctl file operations have the same prototype so they can both point to the same function, which works great almost all the time when all the commands are compatible. One exception is the s390 architecture, where a compat pointer is only 31 bit wide, and converting it into a 64-bit pointer requires calling compat_ptr(). Most drivers here will never run in s390, but since we now have a generic helper for it, it's easy enough to use it consistently. I double-checked all these drivers to ensure that all ioctl arguments are used as pointers or are ignored, but are not interpreted as integer values.
