From 4c9a22f43f1d170f72af185e499e4ad9cdceb789 Mon Sep 17 00:00:00 2001 From: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Wed, 29 Oct 2025 06:59:22 +0000 Subject: [PATCH 1/7] Add GitHub Action workflow for TPM corruption testing This workflow provides a reproducible test case for the TPM corruption bug that occurs when filling the TPM with objects until storage exhaustion. The workflow: 1. Builds commit 1a7f7d71b98dbffbfd4ad77f0c77c8c573a2c5d2 (buggy version) 2. Runs corruption test by filling TPM with AES keys 3. Captures corrupted NVChip as artifact for analysis 4. Builds PR version of wolfPKCS11 5. Tests PR version against corrupted state This serves as a foundation for developing and testing the TPM corruption repair function.

Remove C_Finalize and unload_library calls from corruption test - These could cause metadata to fix itself upon closing - Use _exit(0) instead to avoid cleanup handlers 2. Update both test programs to use C_GetSlotList instead of hardcoded slot 1 - More robust and portable across different CI environments 3. Update access_test expectations to properly handle migration - Treat CKR_USER_PIN_NOT_INITIALIZED (0x00000102) as migration bug - Provide clear error messages distinguishing migration vs corruption issues - Expect login to succeed after proper migration is implemented These changes prepare the workflow for the upcoming migration/repair function that will detect old-format tokens and set WP11_TOKEN_STATE_INITIALIZED flag.
