Hi,
Per https://datatracker.ietf.org/doc/html/draft-tschofenig-rats-psa-token-07 (which is latest spec I can find for profile 1 token):
The Certification Reference claim is used to link the class of chip and PSA RoT of the attesting device to an associated entry in the PSA Certification database. It MUST be represented as a thirteen-digit [EAN-13<https://www.gs1.org/standards/barcodes/ean-upc>].¶<https://datatracker.ietf.org/doc/html/draft-tschofenig-rats-psa-token-07#se…>
Linking to the PSA Certification entry can still be achieved if this claim is not present in the token by making an association at a Verifier between the reference value and other token claim values - for example, the Implementation ID.¶<https://datatracker.ietf.org/doc/html/draft-tschofenig-rats-psa-token-07#se…>
psa-certification-reference-type = text .regexp "[0-9]{13}"
psa-certification-reference = (
? psa-certification-reference-key =>
psa-certification-reference-type
)
But in the tf-m-tools repo:
iat-verifier\iatverifier\psa_iot_profile1_token_claims.py it checks for PSA 2.0 profile HW version which is EAN-13 + 5.
class HardwareVersionClaim(AttestationClaim):
"""Class representing a PSA Attestation Token Hardware version claim"""
def verify(self, token_item):
self._check_type('HARDWARE_VERSION', token_item.value, str)
value_len = len(token_item.value)
expected_len = 19 # 'EAN13-Version' 13 + 1 + 5. e.g.:0604565272829-10010
if len(token_item.value) != expected_len:
msg = 'Invalid HARDWARE_VERSION length; must be {} characters, found {} characters'
self.verifier.error(msg.format(expected_len, value_len))
for idx, character in enumerate(token_item.value):
if character not in string.digits:
if idx != 13 or character not in '-':
msg = 'Invalid character {} at position {}'
self.verifier.error(msg.format(character, idx+1))
It seems like this was changed 3yrs ago:
SHA-1: 8ac8d17d15353c7f7933ae8065646946ae47f993

Hi team,
Can you help me with this statement that "Currently, the TF-M Secure Storage service implements PSA Protected Storage version 1.0-beta2. There is not yet an implementation of PSA Internal Trusted Storage in TF-M."
Our SoC does NOT have internal flash, but we have OTP where we keep the confidential data. Can you help how to handle this ITS situation. I wonder if PSA level-2 certification requires ITS? Thanks

Hi Antonio,
I figured it out. I wasn’t including secure_fw/partitions/crypto/tfm_mbedcrypto_include.h properly so attestation was linking directly to the PSA Crypto function implementation instead of the client interface. I’m surprised it did not complain about a symbol collision without having the mbedcrypto__ prefix. The PSA crypto API implementation source files were “PRIVATE” so I’m not sure how attestation was able to link to them at all.
Regards,
Brian

Hi Brian,
we can't reproduce exactly that mixture easily but I don't think that should affect how the partition code gets linked to the interface code. Regardless of the type of partition (SFN/IPC) the linking of the interfaces should remain the same, i.e. your setup should not be able to link at all directly with the crypto library that provides the PSA Crypto APIs.
Thanks, Antonio

We ran this test on a FVP model and stepped through
`tfm_attest_test_1001`. Please find attached a screenshot of the call stack.
Function in `attest_core` (in the Attestation partition) invokes
function in the `tfm_crypto_api`. This request is routed by the Secure
Partition Manager (SPM) into the Crypto partition via `psa_call()`.

Hi,
Assuming Isolation Level 1 and IPC backend, I'm using Attestation partition with SFN model with stateless handle and a custom Crypto partition using IPC model with stateless handle. My custom Crypto partition includes a PSA crypto wrapper which defines all the PSA Crypto APIs to use HW crypto. We used IPC since we want to be able to support isolation level 2-3 in the future.
When the Attestation partition make calls to PSA Crypto (psa_hash_setup for example), should it use a psa_call() to the Crypto Partition? That is what I had expected since the crypto partition is IPC model but I'm seeing it call the PSA crypto code directly. Also, it appears to provide client side psa_hash_operation_t directly to the psa_hash_setup which is expecting the full operation struct.
Is my configuration valid? How should it work?

Hi Roman,
I tried to look in the ELF spec that I could find by googling, but what I can find online doesn't mention the topic of alignment requirements at all other than a brief mention of how the base address and align requirements must be coherent. How the requirement on alignment propagates from sections to execution regions to load regions is still something that I am trying to understand as I can't find an exhaustive description. The info I shared below stem from a personal conversation that I had with the compiler team internally here in Arm, I have now asked for a reference, will revert back to you in case I get one.
[cid:0aef50f0-9105-480f-8090-06cfaa06b8d3]
Only explicit mention of alignment that I could find is in the armlink manual in section 3.3.3.
[cid:ef5c45ef-7d67-433c-9aba-b8fd7cf0d1c0]
The suggestion from the compiler team are as I mentioned:
1. just disable the strict checks on alignment (i.e. the linker will be then allowed to add padding as required to meet the constraint imposed by the base address of the load region and the ALIGN attributes, by suppressing the diagnostic or using --legacyalign (on a side note, I believe this is the default behaviour on GCC linker for example)
2. rewrite the scatter file to have all the input sections without alignment requirements in the output section where the vector reside, and then have another output section just after the first output section (i.e. with base address +0) to put all the other input sections with increased alignment. As a side note, the suggestion is to also align base addresses of sections using AlignExpr(+0, 4096) (for example, to align to 0x1000) rather than forcing ALIGN attributes. Note that this shouldn't be too complex to attain point 2 but it is something that at the moment we can't work on, but happily merge it in if you're willing to provide a patch for it. Your suggestion of having multiple output section is as well doable, but probably enough to have two of them.
Will get back to you in case I get some more reference about how the alignment requirements in ELF propagate from input section to output sections just to confirm on the spec itself.
Hope this helps, please let me know if any questions!
Thanks, Antonio

Subject: RE: Weird behavior of Clang linker
Hi Antonio,
We have a use case when output section has following list of input sections:
* Vectors with alignment by 0x400.
* Partitions sections with alignment by 0x1000.
As result output section alignment is 0x1000 and address is incorrect. So, probably it’s necessary to create a separate output section for each input section.
Can you share a link to ELF specification with requirements for output section alignment?
Best regards,
Roman.

Hi Bohdan,
For reference, this is due to armlink being strict on following the ELF specification for which the region alignment is derived as the maximum alignment of the input sections. You can relax this requirement with armlink by either using the --legacyalign option (although it's being deprecated) or suppressing the diagnostic --diag_suppress=6244. In the future, we could try to reorganize the scatter file for the armclang toolchain to avoid using directly ALIGN attributes and align the base address of the execution regions using AlignExpr() instead, but even with this strategy, any alignment requirement which stems from using .aligned directive in assembly or attribute __ ((aligned)) attributes will influence the input sections alignment, hence it will require a deeper restructuring of the scatter file, possibly moving sections with increased alignment in a separate load region just after LR_CODE which must have a base address that forces a natural alignment.
Hope this helps.
Thanks, Antonio

Subject: [TF-M] Weird behavior of Clang linker
Hi all,
Our platform uses 4KBs alignment in linker files (as this is the requirement of our protection HW).
For this reasons I have introduced tfm_s_linker_alignments.h.
Everything works fine with GCC but we have a problem with Clang. The problem is that Clang requires LR_CODE to have same alignment as other sections inside of it.
Following are the steps to reproduce the issue:
1. Set TFM_LINKER_DEFAULT_ALIGNMENT to 0x1000 in tfm_s_linker_alignments.h
2. Build AN521 with following command line
cmake -S . -B build_an521 -DTFM_PLATFORM=arm/mps2/an521 -DTFM_TOOLCHAIN_FILE=./toolchain_ARMCLANG.cmake
Expected result:
Everything works fine
Actual result:
Error: L6244E: Load region LR_CODE address (0x10080400) not aligned on a 4096 byte boundary.
This error is weird because there is no explicit alignment assigned to LR_CODE region.
Would appreciate a help on this as it is a blocking issue for us.

Hi, does TF-M use LTO? I didn't see any flags to disable it in toolchain_GNUARM.cmake. I think for GCC, it's enabled by default if no flag is set.

Hello,
We're kicking off the release process for TF-Mv2.2.0, starting with the TF-Mv2.2.0-RC1 tag.
As part of this release phase, we're also updating the previous version to TF-Mv2.1.2, which includes critical bug fixes and support for new platforms. New TF-Mv2.1.2-RC1 tag will follow shortly.
After completing initial testing on the reference platform and addressing all identified issues, we'll reach out to platform owners to verify TF-M on platforms not available in LAVA. Please note, the verification might be requested on a different tag by that time.
Let me remind that the code is not frozen, and development can be continued on the main branch as described in TF-M Release Process<https://tf-m-user-guide.trustedfirmware.org/releases/release_process.html#r…>.
Thanks,
Anton
