xtest_tee_test_1014 fail (CFG_SECURE_DATA_PATH)

[408419237]

Hi, excuse me.
I failed to run tee_xtest 1014.
I look at tee_register_buffer->TEEC_RegisterSharedMemoryFileDescriptor->ioctl(ctx->fd, TEE_IOC_SHM_REGISTER_FD, &data) but optee_linuxdriver does not have a TEE_IOC_SHM_REGISTER_FD definition.
I want to ask whether tee_xtest 1014 can be successfully executed?
Is the CFG_SECURE_DATA_PATH function supported?
thanks!

Can you help me answer that? Thank you very much. @etienne-lms

Hi @408419237,
Could you tell us what do you refer to when mentioning optee_linuxdriver?
CFG_SECURE_DATA_PATH is supported in OP-TEE OS but the Linux optee driver does not especially since ION staging drive rhas been removed from the kernel source tree in v5.10. See linaro-swg/linux#91 and linaro-swg/linux#101.

optee_linuxdriver hasn't been used in a long time. It was deprecated in 2016 and replaced by the OP-TEE driver in the mainline kernel.

Does that mean tee xtest 1014 is not supported yet?
I see TEE_IOC_SHM_REGISTER_FD in optee_client，But I didn't see it in the optee driver.only TEE_IOC_SHM_REGISTER.
thanks.

This version I'm looking at, I think it's new.Thanks.
