TBBR: Question about the available Non Volatile Counters

by Rares Constantin

Hi, I have a question regarding the TBBR implementation for non-volatile counters in TF-A. While looking through the code and documentation for Trusted Boot authentication options, it was not clear why there are only two non-volatile counters for the Trusted and Non-Trusted worlds (`TRUSTED_FW_NVCOUNTER` and `NON_TRUSTED_FW_NVCOUNTER`). This is true for the Arm DEN0006D specification, but it was retired and ARM DEN0072 is the current specification. Is there any specific reason why there isn't a counter for each authenticated image declared and created by `cert_create` or is the retired specification the only reason? This limits the non-volatile counter extensions for all certificates, meaning that the Trusted OS content certificate for example cannot be authenticated with another extension, unless I add a custom certificate with another non-volatile counter extension and a new command line option. To quote the ARM DEN0072 TBBR specification [source: https://developer.arm.com/documentation/den0072/latest]: "It is recommended to implement as many version counters as there are images, where each image can use a separate counter without affecting other images. However, the number of rollback counters that can practically be supported is implementation dependent.". Thank you!

question about encryption

by 林觀明

Hi I tried to turn on encryption in BL31. And, I met some trouble. Here is my code. ``` static struct plat_io_policy policies[] = { ... [BL31_IMAGE_ID] = {&enc_dev_handle, &bl31_uuid_spec, check_enc_fip}, .... [ENC_IMAGE_ID] = {&fip_dev_handle, NULL, check_fip} } int plat_get_image_source(...) { ... policy = &policies[image_id]; ret = policy->check[policy->image_spec]; ... } static int check_fip(const uintptr_t spec) { int ret; ret = io_dev_open(fip_dev_con, (uintptr_t)NULL, &fip_dev_handle); if (ret) { ERROR("io_dev_open failed for FIP (%d)\n", ret); return ret; } ret = io_dev_init(fip_dev_handle, fip_image_id); if (ret) { ERROR("io_dev_init failed for FIP image id %lu (%d)\n", fip_image_id, ret); io_dev_close(fip_dev_handle); } return ret; } static int check_enc_fip(const uintptr_t spec) { int result; uintptr_t local_image_handle; /* See if a Firmware Image Package is available */ result = io_dev_open(enc_dev_con, (uintptr_t)NULL, &enc_dev_handle); if (result) { ERROR("io_dev_open failed for FIP (%d)\n", result); return result; } result = io_dev_init(enc_dev_handle, (uintptr_t)ENC_IMAGE_ID); if (result != 0) return result; return result; } ``` But, I can't boot successfully. Below is log. ``` INFO: Image id=3 loaded: 0x40800000 - 0x4080e299 INFO: BL2: Loading image id 5 WARNING: ===== allocate_dev_info 1 ===== WARNING: ==== -12 ==== ERROR: io_dev_open failed for FIP (-12) ERROR: Image id 11 open failed with -12 WARNING: Failed to obtain reference to image id=11 (-12) ERROR: BL2: Failed to load image id 5 (-12) ``` And, I found root cause in `allocate_dev_info` and `free_dev_info` in `drivers/io/io_fip.c` In `allocate_dev_info`, there is a count, `fip_dev_count`, increasing by 1 after calling `fip_dev_open` There is a check. The value of MAX_FIP_DEVICES is 1. ``` if (fip_dev_count < (unsigned int)MAX_FIP_DEVICES) { unsigned int index = 0; result = find_first_fip_state(0, &index); assert(result == 0); /* initialize dev_info */ dev_info_pool[index].funcs = &fip_dev_funcs; dev_info_pool[index].info = (uintptr_t)&state_pool[index]; *dev_info = &dev_info_pool[index]; ++fip_dev_count; } ``` And, in `fip_dev_close`, The `fip_dev_count` will be decreased by 1. However, The root casue is it call fip_dev_open but not calling fip_dev_close. It cause the `fip_dev_count` not be decreased by 1. Now, I have two solution. 1. Increasing the MAX_FIP_DEVICES, it will be working. 2. Add the io_dev_close in `enc_dev_close` in `driver/io_/io_encrypted.c`. And, it will call the fip_dev_close. It will be working. Do you have any idea in this solution ? Which solution is more general ? Thanks !
