Hi Robert, Great! I gave up to convince about the first point https://developer.trustedfirmware.org/T428 As you are from ARM, hope, you will able to push through all your improvements. Thanks, Andrej Butok -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Robert Rostohar via TF-M Sent: Thursday, September 12, 2019 12:34 PM To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] TF-M / CMSIS-Pack Alignment Hi, We are looking into providing TF-M as a CMSIS-Pack [1] and have discovered a few issues in TF-M that are currently blocking us. 1. Crypto headers ./interface/include/psa clash with headers from mbed-crypto .include/psa It seems that TF-M copies the crypto headers from mbed-crypto folder ./include/psa into folder ./mbedcrypto/psa. However TF-M also provides different crypto headers in folder ./interface/include/psa. TF-M modules typically include "psa/crypto.h" except crypto service modules which include "mbedcrypto/psa/crypto.h" through "tfm_mbedcrypto_include.h". The problem is that in our tools both include folders (./include from mbed-crypto installation and ./interface/include from TF-M) are in the global search path causing wrong headers being used. Another issues is the use of "mbedcrypto" prefix in include "mbedcrypto/psa/crypto.h". We have mbed-crypto already installed and copying crypto headers would not be needed when using include "psa/crypto.h". 1. Device header TF-M currently uses "cmsis.h" as the device header. This is not compliant with CMSIS [2] which defines the naming convention for device headers, startup files and system configuration files. Silicon vendors typically define header filenames that match their device names. The device agnostic way proposed by CMSIS is to use a preprocessor define CMSIS_device_header that reflects the actual device name and is provided by the build environment. We suggest to replace: #include "cmsis.h" with: #include CMSIS_device_header This would affect the following modules: ./secure_fw/core/arch/tfm_arch_v8m_base.c ./secure_fw/core/arch/tfm_arch_v8m_main.c ./secure_fw/core/arch/include/tfm_arch.h ./platform/ext/target: various target files 1. Conditional inclusion of secure services: Storage, Crypto, Attestation Our concept is based on software components and we have described each secure service as a single component that is user selectable. This requires conditional inclusion of a secure service based on preprocessor definitions. TF-M already supports this for secure services Audit Logging (#ifdef TFM_PARTITION_AUDIT_LOG) and Platform (#ifdef TFM_PARTITION_PLATFORM) and also for all test services (#ifdef TFM_PARTITION_TEST_...). We suggest to add this also to secure services Storage (#ifdef TFM_PARTITION_STORAGE), Crypto (#ifdef TFM_PARTITION_CRYPTO) and Attestation (#ifdef TFM_PARTITION_INITIAL_ATTESTATION). This would affect the following modules: ./secure_fw/services/tfm_partition_defs.inc ./secure_fw/services/tfm_service_list.inc ./secure_fw/services/tfm_spm_db.inc ./secure_fw/ns_callable/tfm_veneers.c ./interface/include/tfm_veneers.h We are aware that those file are supposed to be autogenerated however we use them directly at this point. Adding the mentioned preprocessor defines should be trivial and would unblock us. 1. Conditional inclusion of individual test suites We have described also test suites as individual components that are user selectable. This requires conditional inclusion of test suites based on preprocessor definitions. TF-M already supports this for some test suites (#ifdef ENABLE_AUDIT_LOGGING_SERVICE_TESTS, ...). We suggest to add this also for all other test suites. Adding conditional inclusion for secure test suites: ./test/framework/secure_suites.c #ifdef ENABLE_SECURE_STORAGE_SERVICE_TESTS #ifdef ENABLE_CRYPTO_SERVICE_TESTS #ifdef ENABLE_INITIAL_ATTESTATION_SERVICE_TESTS Adding conditional inclusion for non-secure test suites: ./test/framework/non_secure_suites.c #ifdef ENABLE_SECURE_STORAGE_SERVICE_TESTS #ifdef ENABLE_CRYPTO_SERVICE_TESTS #ifdef ENABLE_INITIAL_ATTESTATION_SERVICE_TESTS #ifdef ENABLE_QCBOR_TESTS 1. Deprecated Invert Test suite Invert test suite seems to be deprecated. Tests do nothing and just return. It would make sense to remove it. When we expose it as a component to the user it unnecessary increases the complexity of having another component that does nothing. 1. Tests on non-secure side include headers from secure side Non-secure software should not include any secure side internal headers (ex: from ./secure_fw/core/include) but only those that are exposed as APIs (./interface/include). The following test suites on the non-secure side include internal headers from secure side: Attestation: attestation_ns_interface_testsuite.c #include "secure_fw/services/initial_attestation/attestation.h" Core Positive: core_ns_positive_testsuite.c #include "test/test_services/tfm_core_test/core_test_defs.h" #include "tfm_core.h" // from ./secure_fw/core/include through core_test_defs.h #include "tfm_plat_test.h // from ./platform/include Core Interactive: core_ns_interactive_testsuite.c #include "test/test_services/tfm_core_test/core_test_defs.h" #include "tfm_core.h" // from ./secure_fw/core/include through core_test_defs.h ./app/tfm_integ_test.c: #include "test/test_services/tfm_core_test/core_test_defs.h" #include "tfm_core.h" // from ./secure_fw/core/include through core_test_defs.h This actually causes a compile error in our build because tfm_core.h defines the LOG_MSG macro (through secure_utilities.h) which clashes with the inline static function LOG_MSG defined in tfm_integ_test.h. We had to patch the tfm_integ_test.c by adding #undef LOG_MSG after the secure header is indirectly included. ./app/main_ns.c: #include "target_cfg.h" // from ./platform/ext/target/<target_name> target_cfg.h from secure side also contains USART driver definitions for non-secure side. This should be decoupled and non-secure side should not include that header. 1. Dummy platform files ./platform/ext/target/<target_name>/dummy_boot_seed.c ./platform/ext/target/<target_name>/dummy_crypto_keys.c ./platform/ext/target/<target_name>/dummy_device_id.c ./platform/ext/target/<target_name>/dummy_nv_counters.c ./platform/ext/target/<target_name>/attest_hal.c Dummy platform files are intended for testing only and provide a quick way of starting to test TF-M even when the platform files are not yet ported to the platform that the customer using. They are identical and duplicated for all existing targets. We propose to remove the mentioned dummy files from each target and put them in a single folder (./platform/ext/target/template). This simplifies maintenance of the files and also provides a single location of those files that are being used as a platform independent component. 1. Console via USART Console on secure side is retargeted to CMSIS USART driver (./platform/ext/common/uart_stdout.c). USART driver Send function is called also from SVC with highest interrupt priority which blocks the USART interrupt and leads to deadlock. This is not manifested with Musca USART drivers which implement blocking send - not compliant with CMSIS USART Driver [3]. It does occur instantly with any other CMSIS compliant USART driver. As far as I understand the console on secure side will be redesigned to cope with that. There are also other issues with using the USART driver: * missing wait while busy after send * missing power on/off This is being address with: https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.tr… It also tries to address printf retargeting issues however this needs another iteration. Console on non-secure side is also retargeted to CMSIS USART driver (./app/main_ns.c) however has less constrains. It has the same issues with using the USART driver: * missing wait while busy after send * missing power on/off This is being address with: https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.tr… It also tries to address printf retargeting issues however this needs another iteration. 1. USART driver implementations for platforms included in TF-M As already mentioned all USART drivers implemented for various platforms included in TF-M are not compliant with CMSIS USART Driver specification [3]. They implement blocking send/receive and no power on/off. Drivers should be rewritten and should pass the CMSIS Driver Validation [4]. Please look into the above issues and help us to overcome them.

Re: [TF-M] Outdated pycrypto dependency in BL2's imgtool.py

by Tamas Ban

Hi all, The following change requires a change in TF-M SW requirements: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1695/ The reason of the change to replace the currently used Python crypto library(pycrypto and pycryptodome) to an actively maintained crypto library (cryptography). CI was already updated. BR, Tamas -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Kevin Townsend via TF-M Sent: 31 July 2019 16:28 To: Thomas Törnblom via TF-M <tf-m(a)lists.trustedfirmware.org> Subject: [TF-M] Outdated pycrypto dependency in BL2's imgtool.py Hi, As part of an effort to enable automatic builds of TF-M in Zephyr, I've been trying to get the TF-M + Zephyr S/NS images building and passing on Zephyr's CI system. The only missing requirements for building TF-M in a clean Zephyr SDK 0.10.1 based environment is the pycrypto module, which is used in the imgtool.py utility, specifically: https://git.trustedfirmware.org/trusted-firmware-m.git/tree/bl2/ext/mcuboot… My concern is that this module is no longer actively maintained (last release was 2013!), and it seems like a poor decision to rely on something that isn't actively maintained when more recent alternative are available. Is there a specific reason to keep this module in the script in favour of something more modern?

Reducing the stack usage of the dummy NV counters implementation

by Jamie Fox

Hi all, While optimising SST stack usage, we found that we were blocked from reducing it further by the stack usage of the dummy NV counters implementation used by all of the development platforms currently maintained in the repo. SST makes calls to the NV counter interface, so any stack used by this implementation gets allocated from the SST stack. The current dummy NV counter implementation reads the entire flash sector containing the counters (generally 4KB) into stack memory, so that it can erase the sector and then re-write the same sector with a counter incremented. It needs to do this because the sector might contain some other data, unrelated to NV counters. I am proposing that we simplify this dummy implementation to assume that the dummy NV counters are the only thing in the sector. Then only the NV counters themselves (currently 28 bytes) need to be read into memory for modification. The downside of this of course is that a whole 4KB flash sector needs to be set aside for the dummy NV counters. This seems bad, but it is worth bearing in mind that this is only a dummy implementation that should never be deployed in a real system. In practice, it seems unlikely to me that we would ever want to make use of the partial-sector left after the dummy NV counters anyway, and no platform currently does. With this change made, the stack allocated for SST can be reduced from 6KB to 2.5KB (in this patch https://review.trustedfirmware.org/c/trusted-firmware-m/+/1775). The change is currently on review here https://review.trustedfirmware.org/c/trusted-firmware-m/+/1918/ Feedback and alternative ideas are welcome 😊 Kind regards, Jamie

feature-twincpu, unable to configure & build

by Thomas Törnblom

I have been tasked with making the twincpu feature work with the IAR toolchain, and I started out trying to build it with clang and gcc but it seems there's some issues with it. I tried using the psoc6 target, but it appears that none of the v6/v7 targets are supported in configs/ConfigDefault.cmake. If I add that the build then fails with a complaint about "Armv6-M/Armv7-M can only support multi-core TF-M now." from tfm_arch_v6m_v7m.h, due to TFM_MULTI_CORE_TOPOLOGY not being set, but that appears to be set in one of the cmake files so I guess something is currently broken. Is this a known issue and is there are known fix? /Thomas -- *Thomas Törnblom*, /Product Engineer/ IAR Systems AB Box 23051, Strandbodgatan 1 SE-750 23 Uppsala, SWEDEN Mobile: +46 76 180 17 80 Fax: +46 18 16 78 01 E-mail: thomas.tornblom(a)iar.com <mailto:thomas.tornblom@iar.com> Website: www.iar.com <http://www.iar.com> Twitter: www.twitter.com/iarsystems <http://www.twitter.com/iarsystems>
