Checking SIP Service Calls range

by Michal Simek

Hi, I have one question about SIP Service Calls range and it's range checking. Based on DEN0028E SIP Service Calls ranges are 0x82000000-0x8200FFFF SMC32: SiP Service Calls 0xC2000000-0xC200FFFF SMC64: SiP Service Calls That's the ranges which we are using for implementing SOC specific SMC handlers and I found that in past it was also added code which is out of this range. Specifically in Xilinx ZynqMP you can see code like this if (is_em_fid(smc_fid)) { return em_smc_handler(smc_fid, x1, x2, x3, x4, cookie, handle, flags); } where EM range is 0x820e0001- 0x820e0003 is out of our range which is assigned to us. But there is no failure at all that we are out of ranged in spec. Shouldn't this be enforced by core itself? That's why I just wanted to know your opinion about it. We will definitely implement better masking to find out that 0x00fe0000 are all zeros. But that bit 16 is based on DEN0028E related to smcccv1.3 which I think we are not supporting now that's why should be 0 too. But definitely some information about this bit should be useful.

Coding guidelines update: Discouraging usage of weak functions

by Sandrine Bailleux

Hi all, As you may know, the TF-A project historically used to make heavy use of weak functions. The code base has numerous examples of them. However, based on previous discussions, I think we have general consensus in the TF-A community that the disadvantages of weak functions outweigh their benefits and for this reason we should discourage introducing new ones. In practice, I think this policy is already enforced most of the time in code reviews but I've now posted a patch that makes it explicit in the project's coding guidelines and provide the rationale behind it. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/19398 Note that TF-A maintainers would still be responsible for enforcing this policy, as the CI system won't flag that for them, mainly because I think there might be legitimate cases for weak functions in rare instances so we'd get some false positives from such checks. We (at Arm) have got plans to gradually convert existing weak functions to strongly-defined implementations across the code base but this will take time. Like I said, I don't expect this change to be too controversial but please raise any concerns you may have in this email thread or on Gerrit. Best regards, Sandrine

[LTS v2.8.0] RC0 tag has been created

by Varun Wadekar

Hello, As announced in the last Tech forum, the code freeze date for the LTS branch was Feb 3, 2023. We have now merged all the patches published on the wiki [1]. The branch is still locked, and all the CI test runs have now been completed. We are trying to root cause one test failure, though. The RC0 tag was created today, and we request platform owners test the branch [2] on their downstream platforms if they wish. We are still on track to release on Feb 10 and will publish more updates shortly. Thanks.

Hi All, We are in the process of migrating from mbedtls-2.28 support to 3.3 support we plan to deprecate mbedtls-2.28 support for TF-A 3.0 Release but would retain support for both 2.28 and 3.3 for TF-A 2.9 lifetime. There is draft implementation available[1] for code review which cleanups and prepares for mbedtls-3.3 support but retaining backward compatibility for mbedtls-2.28. Please let us know if there any objections to deprecation of mbedtls-2.28 in TF-A 3.0. -- Thanks Govindraj [1]: https://review.trustedfirmware.org/q/topic:%2522mbedtls3.3_support%2522 <https://review.trustedfirmware.org/q/topic:%2522mbedtls3.3_support%2522>

Query BL31 version from NWd

by Varun Wadekar

Hi, Happy new year! For NVIDIA Tegra platforms, we need the capability to query the BL31 version (e.g. 2.7, 2.8, 2.8.x) from the NWd at runtime. I could not find an FID that returns this value. I propose we introduce a new runtime service in bl31 that returns the version_string to the NWd to support this requirement. Thoughts? -Varun

Post-boot loading of OP-TEE

by Jens Wiklander

Hi, The recent patch [1] for the OP-TEE Dispatcher in TF-A proposes a way of post-boot loading OP-TEE by the Linux kernel with signature verification in the normal world only. This has previously been discussed in this mail thread [2] about half a year ago. Ultimately, it was concluded that this should in principle be accepted upstream as a platform choice to allow this or not. There are concerns that what we have in upstream TF-A should serve as good examples, and trusting the normal world to verify secure world software might not meet that criterion. There are also concerns about adding signature verification to BL31 Leaving the secure world wide open until the Linux kernel has been able to successfully load and verify an OP-TEE binary seems very risky. Even if it's claimed that the normal world can be trusted at this point, we're still giving up a critical level of defense without a good reason. I've started to review [1], but it should not be accepted for merging without support and approval from other maintainers. I would like to explore other options in this mail thread. In [2] it was suggested that a remnant of bl2 could be kept to verify OP-TEE before starting to execute it. This could be taken one step further and load a limited OP-TEE at boot which later is updated live, almost like what's discussed in [3]. This should minimize the impact on TF-A and also leave OP-TEE in charge of accepting an update instead of a divided responsibility between the normal world and TF-A. [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/18635 [2] https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.… [3] https://github.com/OP-TEE/optee_os/issues/5699 Thanks, Jens

Runtime loading of SEL-1

by Jeffrey Kardatzke

Hello, I'm working on a project for ChromeOS where we would like to be able to load the BL32 payload (OpTee) for SEL-1 after the linux kernel has booted rather than during the usual BL32 stage. We would do this via an SMC we would add which would take the OpTee image from linux and then have EL3 load it and perform the init for SEL-1 at that time. The reasoning behind this is that it's much easier to update the rootfs than the FW on our devices, and we can still ensure the integrity of the OpTee image if we load it early enough after the kernel boots. The main questions I have are if there are any issues people would be aware of by loading it after linux boots rather than during the usual BL32 stage? And I would definitely want to upstream this work if it's something we can do. Thanks, Jeffrey Kardatzke Google, Inc.

Question about using rme for smmuv3

by Chenxu Wang

Hi all, I test the SMMUv3 on FVP_Base_RevC-2xAEMvA_11.20_15, and my TF-A is the branch "arm_cca_v0.3". When I boot my FVP, I set the following commands: -C pci.pci_smmuv3.mmu.SMMU_ROOT_IDR0=3 \ -C pci.pci_smmuv3.mmu.SMMU_ROOT_IIDR=0x43B \ -C pci.pci_smmuv3.mmu.root_register_page_offset=0x20000 \ -C cluster0.rme_support_level=2 \ -C cluster1.rme_support_level=2 \ Based on the FVP manual, the SMMU base is 0x2b40_0000, and I think the SMMU Root Control Page should be 0x2b42_0000. Thus, I add the mapping to this region in plat_arm_mmap[], as: MAP_REGION_FLAT(0x2b420000,(0x2b430000-0x2b420000),MT_MEMORY | MT_RW |MT_ROOT) Then I try to access the SMMU_ROOT_IDR0 register in TF-A. Based on the manual, its offset is 0x0, so I read 0x2b42_0000. However, it returns 0x0, which is not what I configured in the boot commands (I think it should be 0x3). Can someone tell me the reason for this? Sincerely, WANG Chenxu
