optee_ftpm + ms-tpm-20-ref support for RSA key sizes 3072 or 4096 causes a panic

by Dennis Kong

Dear community: I apologize in advance if this is the incorrect place to solicit for input on an issue I am having when enabling support of RSA key sizes > 2048. The environment is described below: TI AM642-EVM board Debian Bookworm running kernel 6.6.100, tpm_ftpm_tee.ko kernel module Uboot booting from sdcard UEFI partition and rootfs partition optee_os version 4.5.0 , 4.6.0, 4.7.0 (no difference in behaviour) optee_client version 4.5.0, 4.6.0, 4.7.0 (no difference in behaviour) optee_ftpm version 4.5.0 or 4.6.0, 4.7.0 (no difference in behaviour) ms-tpm-20-ref commit id 98b60a44aba79b15fcce1c0d1e46cf5918400f6a and e9fc7b89d865536c46deb63f9c7d0121a3ded49c Due to issues with RPMB, we decided to use REE_FS instead. Everything works correctly when I create RSA 2048 keys using tpm2-openssl and related tools: sudo tpm2_createprimary -C o -G rsa2048 -g sha256 -c primary.ctx, When I try rsa3072 or 4096, I get errors from the command line response saying invalid input parameters. I changed the ms-tpm-20-ref include file TpmProfile.h to set RSA_3072 and RSA_4096 macros both to (ALG_RSA && YES). After rebuilding and running, I now get an optee panic for ANY RSA key request INCLUDING rsa2048. I read suggestions to increase the MAX_COMMAND_SIZE/MAX_RESPONSE_SIZE on both the kernel driver tpm_ftpm_tee.ko and also optee_os/optee_ftpm, as well to increase relevant TA_STACK_SIZE and TA_HEAP_SIZE and TA_DATA_SIZE, but nothing seems to change the panic output: sudo tpm2_createprimary -C o -G rsa2048 -g sha256 -c primary.ctx============================================================ E/TC:? 0 E/TC:? 0 TA panicked with code 0xffff0007 E/LD: Status of TA bc50d971-d4c9-42c4-82cb-343fb7f37896 E/LD: arch: aarch64 E/LD: region 0: va 0x40005000 pa 0x9e8b0000 size 0x002000 flags rw-s (ldelf) E/LD: region 1: va 0x40007000 pa 0x9e8b2000 size 0x008000 flags r-xs (ldelf) E/LD: region 2: va 0x4000f000 pa 0x9e8ba000 size 0x001000 flags rw-s (ldelf) E/LD: region 3: va 0x40010000 pa 0x9e8bb000 size 0x004000 flags rw-s (ldelf) E/LD: region 4: va 0x40014000 pa 0x9e8bf000 size 0x001000 flags r--s E/LD: region 5: va 0x40015000 pa 0x9e934000 size 0x011000 flags rw-s (stack) E/LD: region 6: va 0x40026000 pa 0x8ebf0000 size 0x002000 flags rw-- (param) E/LD: region 7: va 0x4006e000 pa 0x9e8c0000 size 0x058000 flags r-xs [0] E/LD: region 8: va 0x400c6000 pa 0x9e918000 size 0x01c000 flags rw-s [0] E/LD: [0] bc50d971-d4c9-42c4-82cb-343fb7f37896 @ 0x4006e000 E/LD: Call stack: E/LD: 0x4006f394 E/LD: 0x40095edc E/LD: 0x4007b5a8 E/LD: 0x400985fc E/LD: 0x40098a70 E/LD: 0x4006fae0 E/LD: 0x400a5508 E/LD: 0x40098b9c D/TC:? 0 user_ta_enter:195 tee_user_ta_enter: TA panicked with code 0xffff0007 D/TC:? 0 release_ta_ctx:670 Releasing panicked TA ctx D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.944680] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.952379] tpm tpm0: tpm_try_transmit: send(): error -53212 D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.963359] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.974241] tpm tpm0: tpm_try_transmit: send(): error -53212 D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.985675] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.993366] tpm tpm0: tpm_try_transmit: send(): error -53212 [ 218.999044] tpm tpm0: tpm2_commit_space: error -14 ERROR:tcti:src/tss2-tcti/tcti-device.c:198:tcti_device_receive()D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 Failed to get response size fd 3, got errno 14: Bad address E[ 219.015351] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 RROR:esys:src/tss2-esys/api/Esys_CreatePrimary.c:404:Esys_Create[ 219.028348] tpm tpm0: tpm_try_transmit: send(): error -53212 Primary_Finish() Received a non-TPM Error ERROR:esys:src/tss2-esys/api/Esys_CreatePrimary.c:135:Esys_CreatePrimary() Esys Finish ErrorCode (0x000a000a) ERROR: Esys_CreatePrimary(0xA000A) - tcti:IO failure ERROR:esys:src/tss2-esys/esys_iutil.c:1145:iesys_check_sequence_async() Esys called in bad sequence. ERROR:esys:src/tss2-esys/api/Esys_FlushContext.c:66:Esys_FlushContext() Error in async function ErrorCode (0x00070007) ============================================================================= The last suggestion I saw was to change my dtb file to include a reserved memory region for optee shared memory and not use the default dynamic shared memory. The issue I have is kernel 6.6.100's tpm_ftpm_tee ignores the "memory-region" dts statement that references the optee_shm reserved memory at at 0xa4000000 in my case. Below is my snippet of the dts file. I heard there are patches in the kernel ftpm driver to support the reserved shared memory, but before I try the patches, can anyone opine whether this could cause the panic that I am seeing? Thanks in advance for anyone who can share any information optee_shm: optee-shm@a4000000 { compatible = "shared-dma-pool"; reg = <0x0 0xa4000000 0x0 0x01000000>; no-map; reusable; }; .... firmware { optee { compatible = "linaro,optee-tz"; method = "smc"; memory-region = <&optee_shm>; }; } Dennis Kong, P.Eng.

Does spmd_group0_interrupt_handler_nwd() need to take into account handling of special INTIDs?

by YANG Jun

Hi there, Do spmd_group0_interrupt_handler_nwd() and spmd_handle_group0_intr_swd() need to take into account handling of special INTIDs? Like ehf_el3_interrupt_handler(): /* * Acknowledge interrupt. Proceed with handling only for valid interrupt * IDs. This situation may arise because of Interrupt Management * Framework identifying an EL3 interrupt, but before it's been * acknowledged here, the interrupt was either deasserted, or there was * a higher-priority interrupt of another type. */ intr_raw = plat_ic_acknowledge_interrupt(); intr = plat_ic_get_interrupt_id(intr_raw); if (intr == INTR_ID_UNAVAILABLE) return 0; Best Regards, Joe Yang

Contributing to Trusted Firmware Armv7-A and Armv8-A

by Waqas Mazhar

Hi all, Hope you are well. I have recently joined this mailing list and am quite keen to contribute to this project but don't know where to start. Currently, I am going through Trusted Firmware A Documentation <https://trustedfirmware-a.readthedocs.io/en/latest/index.html> document and Gerrit code reviews <https://review.trustedfirmware.org/q/status:open+-is:wip> to develop some initial understanding and familiarity about the project. As a first step, I am trying to understand areas where I can contribute. Is there any simple issue for me to pick? I am happy to volunteer. Looking forward to hearing from you, Waqas
