Re: [TF-A] [RFC] New feature in TF-A to load encrypted FIP payloads: address implementation concerns

For now, I've added in our internal CI a simple build test based on the build instructions you've provided in the patch set. This will at least make sure we do not break the build inadvertently in the future. But as you say, going forward, we should plan for proper testing on QEMU. I am hoping we will soon be able to extend the OpenCI [1] and add this support there.

Actually this is something you have access to, it's a matter of adding a line in docs/change-log-upcoming.rst in the TF-A source tree. Regards, Sandrine

Re: [TF-A] [RFC] New feature in TF-A to load encrypted FIP payloads: address implementation concerns

by Sumit Garg

Hi Everyone, I have tried to address most of the implementation concerns with updated patch-set [1] as follows: *Concern*: Firmware encryption bit needs to be signed *Address*: Moved the firmware encryption bit from FIP ToC header to "io_uuid_spec_t" struct which is part of "plat_io_policy" that is embedded in the boot-loader (BL1 or BL2) and hence firmware encryption bit is signed. Also, with this implementation fip_tool is no longer aware of encryption and just encrypted binaries are piped to fip_tool. *Concern*: Capability to encrypt with different keys for different images *Address*: Passed "img_id" buffer reference as an argument of "plat_get_enc_key_info()" API. So that platforms may choose to either provide a unique key per firmware image or just derive a key from HUK per firmware using "img_id" buffer as a salt. *Concern*: Coupling of FIP and encryption layer *Address*: Firstly I think we all can agree that encryption layer provides confidentiality protection specific to IO storage. Secondly FIP is actually a packaging layer that sits over actual IO layer and having the encryption layer coupled with FIP provides an abstraction layer for any FIP payload which in turn provides the following features: 1. Allows the firmware certificates to be encrypted as well to protect against cloning satisfying R050_TBBR_PROTECTION requirement. 2. Allows the firmware configuration data to be encrypted as well. 3. Provides a capability to have a secure key store as FIP payload which is protected using HUK. *Concern*: Allow usage of alternative verify-then-decrypt method *Address*: A platform could disable this encryption layer and implement decryption as part of "bl2_plat_handle_post_image_load()". Please let me know in case I missed any implementation concerns and feel free to provide your feedback on updated patch-set [1].

Re: [TF-A] Incorrect section attributes with ALLOW_RO_XLAT_TABLES=1

by Petre-Ionut Tudor

Hi Masahiro, That warning is expected. GCC complains about this, since tf_base_xlat_table is not constant and we are asking it to be put in a read-only section (see the REGISTER_XLAT_CONTEXT_RO_BASE_TABLE macro). This is fine since: * We only want the base table to be read-only after the tables have been initialized. The only time we change tf_base_xlat_table is when we initialize it, and at that point in the platform setup sequence the MMU is off, so permissions have no effect. * We never write to this with the MMU on (it's the level 1 translation table), so there is no danger of generating MMU faults. I hope this answers your question. Thanks Petre ________________________________ From: TF-A <tf-a-bounces(a)lists.trustedfirmware.org> on behalf of Masahiro Yamada via TF-A <tf-a(a)lists.trustedfirmware.org> Sent: 06 March 2020 12:30 To: tf-a(a)lists.trustedfirmware.org <tf-a(a)lists.trustedfirmware.org> Subject: [TF-A] Incorrect section attributes with ALLOW_RO_XLAT_TABLES=1 Hi.
