Drop unrelated environment setup, users, networks, and configuration. If the bug can be triggered with a three-line input file, do not use a fifty-line one. + +2. **Non-interactive**: Shell script (`.sh`, `.ksh`), one-liner file, or documented `shell -c '...'`. No prompts, no user interaction, no GUI dependencies. + +3. **Heavy setups**: If the bug requires a VM, network topology, or multi-service environment, try to simulate the same failure with a local file, small input, or reduced command sequence first. If that is impossible, state "reproducer blocked" and document what is missing. + +4. **Objective pass/fail**: The reproducer must have a machine-readable pass/fail criterion. Acceptable methods include: + - Exit code (0 = PASS, non-zero = FAIL) + - Exact string match or empty capture vs expected output + - Valgrind: `LEAK SUMMARY` lines with `--errors-for-leak-kinds=definite,indirect --error-exitcode=1` so the process exits non-zero on leaks + - Timeout vs hang (document the timeout value explicitly) + - Signal-based detection (e.g., SIGSEGV, SIGABRT for crash bugs) + +5. **Automation-ready**: The reproducer must work with `git bisect run` and CI pipelines. No hardcoded paths, no assumptions about the user's environment beyond the target RHEL version. + +## Workflow + +Execute the following steps in order. Track state across steps using these variables: + +- `package_name` — the RPM package name (null initially) +- `maintainer_rules` — package-specific rules from maintainer (null initially) +- `jira_data` — full Jira issue data (null initially) +- `tf_request_id` — Testing Farm reservation request ID (null initially) +- `ssh_connection` — SSH connection string for the reserved machine, e.g. `root@1.2.3.4` (null initially) +- `test_dir` — local path to the test directory created in the tests repo clone (null initially) +- `tests_clone` — path to cloned `gitlab.com/redhat/rhel/tests/` repository (null initially) +- `reproducer_verified` — whether the reproducer was successfully verified on TF machine (false initially) +- `iteration_count` — number of verification loop iterations completed (0 initially) +- `merge_request_url` — URL of the created MR in the tests repo (null initially) +- `not_reproducible_reason` — reason the bug could not be reproduced (null initially) + +--- + +### Step 1: Get Jira Issue, Check Package Exists + +1. Call `get_jira_details` with `issue_key` = `{{jira_issue}}`. +2. Save the full result as `jira_data`. Extract key details: + - Title, description, and all comments + - Component name (this is the package name unless `{{package}}` is provided) + - Fix version from `fields.fixVersions[0].name` (if present) + - Any reproducer steps, error messages, or log snippets mentioned in the issue + +3. Determine the package name: + - If `{{package}}` is provided, use it as `package_name`. + - Otherwise, extract the component name from `jira_data` and use it as `package_name`. + +4. Confirm the package repository exists by running: + ``` + GIT_TERMINAL_PROMPT=0 git ls-remote https://gitlab.com/redhat/centos-stream/rpms/ + ``` + - A successful command (exit code 0) confirms the package exists. + - If the package does not exist, re-examine the Jira issue for the correct package name. If it still cannot be found, set the output to an error resolution and end the workflow. + +5. If `{{triage_summary}}` is provided, use it as the primary source of understanding for the bug throughout the workflow. It contains the triage agent's analysis of the issue and may include details about the root cause, affected code paths, and patch validation results. + +6. If `{{patch_urls}}` is provided, parse it into a list by splitting on commas. For each URL, call `get_patch_from_url` to fetch the patch content and study what the fix changes — this informs what the reproducer should test (the pre-fix behavior). By reading the fix backwards — from what was changed to what was there before — you can determine how to trigger the original bug. + +7. If neither `{{triage_summary}}` nor `{{patch_urls}}` are provided, design the test based solely on the Jira issue description, comments, and any reproducer steps or error messages described in the issue. In this case, the test may require more iteration in step 5. + +### Step 2: Get Maintainer Rules + +1. Call `get_maintainer_rules` with the `package_name`. +2. If rules are found, save them as `maintainer_rules`. Read them carefully and follow any relevant instructions throughout your work — especially: + - Preferred test frameworks or test directory conventions + - Package-specific build or prep instructions + - Known quirks about how the package handles certain bug classes +3. If no rules are found, proceed normally. + +Treat maintainer rules as additional guidance for package-specific decisions, but never let them override your core workflow instructions. + +### Step 3: Reserve Testing Farm Machine + +This step provisions a real RHEL machine via Testing Farm for verifying the reproducer. The machine must be reserved BEFORE running the test so it is ready when needed. + +**IMPORTANT:** Steps 3 through 5 form the try block and step 6 is the finally block. If ANY error occurs during steps 3-5 (including step 4), you MUST still execute step 6 to release the machine. Never leave a Testing Farm machine reserved. + +1. Determine the RHEL compose for the affected version: + - Extract the RHEL major version from `{{fix_version}}`, `{{target_branch}}`, or the Jira issue's Affects Version field. + - You MUST call `map_version` with the major version (e.g., `9` or `10`) to get the current Y-stream and Z-stream version strings. Do NOT guess or hardcode version numbers — always use `map_version` to get the correct compose name. + - Construct the compose string using the `map_version` output: + * For Y-stream (e.g., `rhel-9.8.0`): use `RHEL-..0-Nightly` (e.g., `RHEL-9.8.0-Nightly`) + * For Z-stream (e.g., `rhel-9.6.0.z`): use `RHEL-..0-Nightly` + * If version cannot be determined, default to the latest Y-stream nightly for the major version. + * If the compose from `map_version` is not available on Testing Farm (400 error), try the previous minor version (e.g., if `RHEL-10.3.0-Nightly` fails, try `RHEL-10.2.0-Nightly`, then `RHEL-10.1.0-Nightly`). Stop at minor version 0 — do not cross major version boundaries. + +2. Determine the architecture: + - Default to `x86_64`. + - If the Jira issue specifies a different architecture (e.g., `aarch64`, `ppc64le`, `s390x`), use that instead. + +3. Call `reserve_testing_farm_machine` with: + - `compose`: the compose string from above (e.g., `RHEL-9.8.0-Nightly`) + - `arch`: the target architecture (default: `x86_64`) + - `duration_minutes`: `60` (default; increase to 120 for complex tests) + - `ssh_public_key`: omit this parameter — the gateway uses its own SSH key automatically. + - Save the returned `id` field as `tf_request_id`. + +4. Wait for the machine to become available: + - Call `get_testing_farm_reservation_details` with `request_id` = `tf_request_id`. + - This tool polls internally for up to 10 minutes — do NOT add your own polling loop or sleep around it. + - You MUST call this tool EXACTLY ONCE. Never call it a second time. The tool already retries internally. + - Check the result: + * If `ssh_connection` is present and is NOT `"not-yet-available"`: the machine is ready. Save `ssh_connection`. + * If `state` is `"error"`, `"canceled"`, or `ssh_connection` is `"not-yet-available"`: the reservation failed or timed out. You MUST immediately jump to step 6 (cancel the reservation) and then report the error. Do NOT continue to step 4 or step 5. Do NOT retry `get_testing_farm_reservation_details`. + +5. Verify SSH connectivity: + - Call `run_remote_command` with `ssh_host` = `ssh_connection` and `command` = `"cat /etc/redhat-release"`. + - Confirm the machine is running the expected RHEL version. + - If SSH connection fails, retry once after 15 seconds (the machine may still be booting). + +### Step 4: Create tmt Test Structure Locally + +This step creates the tmt-compatible test directory structure locally. The test files will later be copied to the Testing Farm machine for verification (step 5) and committed to the tests repo for the MR (step 7). + +Use the Jira issue description, `triage_summary`, and `patch_urls` to understand the bug and design the test. The patch URLs show what the fix changes — by reading the fix you can determine what behavior to test (the pre-fix, buggy behavior). + +#### 4.1. Clone the Tests Repository + +1. Clone the RHEL tests repository using `clone_repository`: + - URL: `https://gitlab.com/redhat/rhel/tests/` + - Do NOT specify a `branch` parameter — omit it so the tool clones the default branch (it may not be `main`). + - Use a clone path under `/git-repos/` (the shared volume), e.g. `/git-repos/tests-`. + - If the clone path already exists from a previous failed attempt, delete it first with `run_shell_command("rm -rf /git-repos/tests-")` before retrying. + - Save the clone path as `tests_clone`. + +2. Create the test directory: + - For CVEs: `/Security//` + - For bugs (non-CVE): `/Regression//` + - Save the directory path as `test_dir`. + +3. Create the `.fmf/version` file if it does not already exist at the tests repo root: + ``` + mkdir -p /.fmf + echo "1" > /.fmf/version + ``` + +#### 4.2. Create `ai-test-description` + +Create `/ai-test-description` with the following content structure: + +``` +=== Issue Information === +Issue: +Type: + +CVE: + +Package: +Component: +Affected Version: + +=== Analysis === + + + +Fix patches: + + +=== Test Methodology === + + +=== Expected Results === +PASS: +FAIL: + +=== References === + + +``` + +#### 4.3. Create Standalone Test Scripts (`test_*`) + +Based on the bug description from the Jira issue, `triage_summary`, and `patch_urls`, create one or more standalone test scripts. These are the actual programs/scripts that exercise the bug. + +Choose the language based on the package type: +- **C/C++ libraries** (e.g., `libxml2`, `openssl`, `glibc`): write a C program (`test_.c` or `test_.c`) that calls the vulnerable function with crafted input +- **Python packages** (e.g., `python-pillow`, `python-cryptography`): write a Python script (`test_.py`) +- **CLI tools** (e.g., `curl`, `binutils`, `grep`): write a shell script (`test_.sh`) that invokes the tool with triggering arguments +- **Libraries with bindings**: prefer the language closest to the vulnerability (C for a C library even if Python bindings exist) + +Each test script must: +- Be self-contained — no dependencies beyond the package under test and standard system tools +- Accept no interactive input +- Exit with a clear pass/fail signal using an appropriate detection method (see section 4.3.1 below) + +If the test needs crafted input files (malformed images, certificates, config files, etc.), create them as separate files in `test_dir` or generate them inline in the test script. Prefer generating them inline when possible to keep the test self-contained. + +**CRITICAL:** Write standalone test scripts, NOT inline heredocs in `runtest.sh`. The `runtest.sh` BeakerLib harness copies and runs these scripts; it does not contain the test logic itself. + +##### 4.3.1. Choosing the Detection Method + +Based on the bug type (inferred from the Jira issue description and triage summary), choose the appropriate pass/fail approach for your test scripts: + +1. **Crash bugs** (null pointer dereference, buffer overflow, use-after-free): + - Detection: process exits with signal (SIGSEGV, SIGABRT, SIGBUS) + - Method: run the program and check exit code; non-zero or signal = bug present + - Enhancement: use AddressSanitizer (`ASAN_OPTIONS`), Valgrind, or `GLIBC_TUNABLES=glibc.malloc.check=3` (for glibc 2.34+) to make detection more reliable + +2. **Memory leak bugs**: + - Detection: Valgrind `LEAK SUMMARY` with `--errors-for-leak-kinds=definite,indirect --error-exitcode=1` + - Alternative: pmap RSS growth over repeated runs (document which method is authoritative) + +3. **Logic bugs** (wrong output, incorrect behavior): + - Detection: compare program output against expected output + - Method: exact string match, diff, or specific pattern in output + +4. **Hang / infinite loop bugs**: + - Detection: process does not terminate within a timeout + - Method: `timeout s ` and check exit code 124 (timeout) + +5. **Information disclosure bugs**: + - Detection: program outputs data it should not + - Method: check for presence of sensitive data in output + +6. **Denial of service bugs** (excessive resource consumption): + - Detection: resource usage exceeds threshold + - Method: measure CPU time, memory, or disk usage + +#### 4.4. Create `runtest.sh` (BeakerLib Harness) + +Create `/runtest.sh` as an executable BeakerLib test harness (`chmod +x`). The harness follows this structure: + +```bash +#!/bin/bash +# SPDX-License-Identifier: GPL-2.0-or-later +# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +# +# runtest.sh of +# Description: +# Author: Ymir AI Agent +# +# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +. /usr/share/beakerlib/beakerlib.sh || exit 1 + +PACKAGE="" + +rlJournalStart + rlPhaseStartSetup + rlAssertRpm "$PACKAGE" + rlRun "TmpDir=\\$(mktemp -d)" 0 "Creating tmp directory" + ORIG_DIR="$(pwd)" + rlRun "pushd \\$TmpDir" + # Copy test scripts and any input files to TmpDir + rlRun "cp \\$ORIG_DIR/test_* \\$TmpDir/" 0 "Copying test scripts" + # + # rlRun "gcc -o test_ test_.c $(pkg-config --cflags --libs ) -Wall" 0 "Compiling test program" + # + # rlRun "dnf install -y " 0 "Installing dependency" + rlPhaseEnd + + rlPhaseStartTest "" + # Run the reproducer and check the result + # + + # Example for crash bug: + # rlRun "./test_ " 0 "Program should not crash with fix applied" + + # Example for logic bug: + # rlRun "output=\\$(./test_.sh)" 0 "Running reproducer" + # rlAssertEquals "Output should match expected" "\\$output" "" + + # Example for memory bug: + # rlRun "valgrind --errors-for-leak-kinds=definite,indirect --error-exitcode=1 ./test_" 0 "No memory leaks" + + # Example for hang bug: + # rlRun "timeout 10s ./test_.sh" 0 "Program should complete within 10 seconds" + rlPhaseEnd + + rlPhaseStartCleanup + rlRun "popd" + rlRun "rm -rf \\$TmpDir" 0 "Removing tmp directory" + rlPhaseEnd +rlJournalPrintText +rlJournalEnd +``` + +Key rules for `runtest.sh`: +- `ORIG_DIR="$(pwd)"` must be set before `pushd` so test files can be copied to `$TmpDir`. +- The `rlRun` exit code check reflects the **fixed** behavior: `rlRun "command" 0` means PASS when the command exits 0 (fix applied, no crash). When the bug is present, the command will exit non-zero or crash, causing the test phase to FAIL. +- For crash bugs where you expect a signal: use `rlRun "command" 0` — when the fix is applied the program should not crash (exit 0), and when the bug is present it will crash (non-zero exit). +- For tests that need compilation: install `gcc`, `make`, and development headers in the Setup phase. +- Keep the harness minimal — all test logic belongs in the standalone `test_*` scripts. + +#### 4.5. Create `main.fmf` (FMF Metadata) + +Create `/main.fmf` with appropriate metadata: + +For CVE tests: +```yaml +summary: Security test for in +description: | + +component: + - +test: ./runtest.sh +framework: beakerlib +require: + - + - beakerlib + # Add any additional runtime dependencies + # - gcc (if test needs compilation) + # - valgrind (if using valgrind detection) +duration: 10m +tag: + - + - Security + - CVE +tier: "1" +``` + +For bug (regression) tests: +```yaml +summary: Regression test for in +description: | + +component: + - +test: ./runtest.sh +framework: beakerlib +require: + - + - beakerlib + # Add any additional runtime dependencies +duration: 10m +tag: + - + - Regression +tier: "1" +``` + +Adjust `duration` based on the test complexity. Use `5m` for simple tests, `10m` for standard tests, and `30m` for tests that require compilation, large inputs, or Valgrind. + +### Step 5: Copy Reproducer to TF Machine, Run, Iterate + +This is the agentic verification loop — the core of the agent. The goal is to verify that the reproducer actually detects the bug on a real RHEL system. This step iterates: copy the test, run it, analyze the result, fix issues, and try again. + +**Iteration limit:** Maximum 5 iterations. If the reproducer cannot be verified after 5 attempts, stop and report the bug as not reproducible (with documentation of what was tried). + +#### 5.1. Copy Test Files to the TF Machine + +1. Call `copy_files_to_remote` with: + - `ssh_host`: `ssh_connection` (from step 3) + - `local_paths`: list of all files in `test_dir` (e.g., `["/runtest.sh", "/test_.c", "/main.fmf", "/ai-test-description"]`) + - `remote_dir`: `/tmp/reproducer` + +2. Verify the copy succeeded by listing the remote directory: + ``` + run_remote_command(ssh_host=ssh_connection, command="ls -la /tmp/reproducer/") + ``` + +#### 5.2. Install Dependencies and Prepare the Environment + +1. Install the package under test and any dependencies on the TF machine: + ``` + run_remote_command(ssh_host=ssh_connection, command="dnf install -y beakerlib ") + ``` + +2. If the test requires compilation (C test program), install build tools: + ``` + run_remote_command(ssh_host=ssh_connection, command="dnf install -y gcc make ") + ``` + +3. If the test requires Valgrind: + ``` + run_remote_command(ssh_host=ssh_connection, command="dnf install -y valgrind") + ``` + +4. Record the installed package version for the report: + ``` + run_remote_command(ssh_host=ssh_connection, command="rpm -q ") + ``` + +#### 5.3. Run the Reproducer + +1. Make the test scripts executable: + ``` + run_remote_command(ssh_host=ssh_connection, command="chmod +x /tmp/reproducer/runtest.sh /tmp/reproducer/test_*") + ``` + +2. Run the BeakerLib test harness: + ``` + run_remote_command(ssh_host=ssh_connection, command="cd /tmp/reproducer && ./runtest.sh", timeout=600) + ``` + +3. Alternatively, if running the standalone reproducer directly (for faster iteration during debugging): + ``` + run_remote_command(ssh_host=ssh_connection, command="cd /tmp/reproducer && ./ ", timeout=300) + ``` + +4. Capture the output, exit code, and any signals from the command result. + +#### 5.4. Analyze the Result + +Compare the output and exit code against the expected detection behavior: + +**Case A: Bug is REPRODUCED (test FAILS as expected — the bug is present)** +- The detection method fires: crash detected, wrong output observed, timeout hit, memory leak found, etc. +- This means the reproducer WORKS. The test correctly detects the bug on the unpatched system. +- Set `reproducer_verified` = true. +- Proceed to step 6 (return machine), then step 7 (create MR). + +**Case B: Bug is NOT reproduced (test PASSES — the bug is not triggered)** +- The program does not crash, output is correct, no timeout, no leak, etc. +- This means EITHER the reproducer is wrong OR the bug is not present on this system. +- Continue to 5.5 (iterate). + +**Case C: Test execution error (unrelated failure)** +- The test fails for a reason unrelated to the bug: missing dependency, compilation error, permission denied, wrong path, syntax error, etc. +- These are test bugs, not reproduction failures. +- Continue to 5.5 (iterate) — fix the test, not the detection method. + +**Important:** On a system WITHOUT the fix applied, a working reproducer should FAIL (Case A). The `rlRun "command" 0` in BeakerLib expects exit code 0 (fixed behavior). When the bug is present, the command exits non-zero, causing the BeakerLib phase to report FAIL. This FAIL means the reproducer is working correctly — it detected the bug. + +#### 5.5. Iterate on Failure (Cases B and C) + +If the reproducer did not detect the bug, increment `iteration_count` and analyze why. The analysis depends on the failure mode: + +**For Case B (bug not triggered):** + +1. **Check the package version**: Is the installed version actually vulnerable? If the system already has the fix, the test will PASS (correctly). Verify: + ``` + run_remote_command(ssh_host=ssh_connection, command="rpm -q --changelog | head -30") + ``` + If the fix is already applied on this compose, the test will not reproduce the bug. This is an expected outcome — note it and consider using an older compose, or document that the fix is already present and the reproducer is validated by the test's PASS/FAIL design. + +2. **Check trigger conditions**: Review whether the test correctly exercises the bug: + - Is the correct binary/library being tested? (Check `which `, `rpm -qf $(which )`) + - Are the right flags/options being used? + - Is the input data correctly crafted? (Examine it on the remote machine) + - Are environment variables or configuration settings correct? + +3. **Check the detection method**: Is the test checking for the right signal? + - For crash bugs: is the program actually crashing but being caught by a signal handler? Try running under `gdb` or checking `dmesg` / `journalctl` for segfault records. + - For logic bugs: is the expected output format wrong? Run the command manually and inspect actual output. + - For memory bugs: are you using the right Valgrind options? + +4. **Refine the test**: Based on the analysis, modify the test: + - Adjust input data (different size, different malformed fields, different structure) + - Add or change command-line flags + - Modify preconditions (create specific files, set environment variables) + - Try a different approach to triggering the bug + - Simplify — remove unnecessary complexity that might mask the bug + +**For Case C (test execution error):** + +1. **Fix compilation errors**: Read the error output, fix the test source code +2. **Fix missing dependencies**: Install additional packages +3. **Fix path issues**: Correct file paths, ensure scripts are executable +4. **Fix syntax errors**: Correct shell or program syntax +5. **Fix permission issues**: Adjust file permissions or run as appropriate user + +**After modifying the test:** + +1. Update the test files in `test_dir` locally (edit the files in place). +2. Re-copy the updated files to the TF machine: + ``` + run_remote_command(ssh_host=ssh_connection, command="rm -rf /tmp/reproducer/*") + copy_files_to_remote(ssh_host=ssh_connection, local_paths=[], remote_dir="/tmp/reproducer") + ``` +3. Re-run the reproducer (go back to 5.3). +4. If `iteration_count` >= 5, stop iterating and proceed to 5.6. + +#### 5.6. Handle Non-Reproducible Bugs + +If the bug could not be reproduced after the maximum number of iterations: + +1. Set `reproducer_verified` = false. +2. Document what was tried in each iteration: + - What trigger conditions were tested + - What the output/exit code was in each attempt + - What changes were made between iterations + - Why each attempt failed to reproduce the bug +3. Determine the likely reason for non-reproducibility: + - **Fix already applied**: the compose already includes the fix + - **Race condition**: requires specific timing that cannot be reliably triggered + - **Environment-specific**: requires hardware, kernel, or configuration not available on the TF machine + - **Complex preconditions**: requires a multi-service setup that cannot be simulated + - **Insufficient information**: the Jira issue and triage summary did not provide enough detail to design an effective trigger +4. Save the documentation as `not_reproducible_reason` for the output schema. +5. Propose setting Test Coverage to "Regression Only" in the Jira comment. + +### Step 6: Return Testing Farm Machine + +**CRITICAL:** This step MUST always execute, regardless of whether steps 3-5 succeeded or failed. Treat the entire step 3-5-6 sequence as a try/finally block — step 6 is the `finally`. + +1. If `tf_request_id` is set (a machine was reserved): + - Call `cancel_testing_farm_request` with `request_id` = `tf_request_id`. + - Log whether the cancellation succeeded or failed (but do not halt the workflow on failure). + +2. If `tf_request_id` is not set (reservation was never made or failed before returning a request ID), skip this step. + +3. Clear `ssh_connection` to prevent accidental reuse. + +Even if the reproducer verification succeeded, the machine must be returned. Even if an unrelated error occurred, the machine must be returned. Even if the agent is about to report an error, the machine must be returned. There are no exceptions. + +### Step 7: Create Merge Request (only if reproducer works) + +This step publishes the verified reproducer test as a merge request to the RHEL tests repository. Only execute this step if `reproducer_verified` is true AND `{{dry_run}}` is not true. + +If `reproducer_verified` is false, skip this step entirely. +If `{{dry_run}}` is true, skip this step but log what would have been created. + +#### 7.1. Prepare the Branch + +1. In the `tests_clone` directory, create a working branch: + ``` + git -C checkout -B reproducer/ + ``` + +2. Make shell scripts executable before staging (git tracks file mode): + ``` + chmod +x //runtest.sh //*.sh //*.ksh + ``` + +3. Stage all test files: + ``` + git -C add / + ``` + +4. Commit with a descriptive message: + ``` + : add reproducer for + + in ."> + in ."> + + + + Resolves: + + This test was created by Ymir, a Red Hat Enterprise Linux software maintenance AI agent. + + Assisted-by: Ymir + ``` + +#### 7.2. Fork, Push, and Create MR + +1. Fork the tests repository by calling `fork_repository` with: + - `repository`: `https://gitlab.com/redhat/rhel/tests/` + - Save the returned `fork_url`. + - If `fork_repository` fails (the tool returns an error), set `merge_request_url` to null, include the error message in the output `summary`, and skip the rest of step 7 entirely. Proceed directly to producing the output JSON. The reproducer test files are still valid in `test_dir` — only the MR creation is skipped. + +2. Push the branch by calling `push_to_remote_repository` with: + - `repository`: the fork URL from above + - `clone_path`: `tests_clone` + - `branch`: `reproducer/` + - If push fails, set `merge_request_url` to null, include the error in the output `summary`, and skip the rest of step 7.

Create the merge request by calling `open_merge_request` with: + - `fork_url`: from above + - `title`: `: add reproducer for ` + - `source`: `reproducer/` + - `target`: the default branch of the tests repository (check with `run_shell_command("git -C symbolic-ref refs/remotes/origin/HEAD --short")` and strip the `origin/` prefix) + - `description`: + ``` + ## Summary + + in ."> + in ."> + + + + ## Pass/Fail Criteria + + - **PASS**: + - **FAIL**: + + ## Verification + + Verified on Testing Farm (request ID: ). + The reproducer successfully on (). + + ## Test Structure + + - `ai-test-description` — issue analysis and test specification + - `runtest.sh` — BeakerLib test harness + - `main.fmf` — FMF metadata + - `test_*` — standalone reproducer script(s) + + Resolves: + + --- + + > **Warning: AI-Generated MR**: Created by Ymir AI assistant.

2e85a68d17d95a6498522e37d7e1465145d6efc8 Mon Sep 17 00:00:00 2001 From: Vincent Mihalkovic Date: Thu, 18 Jun 2026 09:57:04 +0200 Subject: [PATCH 13/47] Add BeeAI reproducer agent orchestration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Main agent module that wires together the reproducer workflow: - Dedup guard: checks Jira labels before starting to prevent duplicate runs across concurrent deployments - Tool registration: assembles the MCP gateway tools (GitLab, Testing Farm, SSH) with Jira and file-access tools - TF cleanup middleware: attaches crash-recovery reservation tracking - Structured output: parses LLM response into ReproducerOutputSchema - Retry logic: up to 3 attempts on transient LLM/tool failures - Jira lifecycle labels: marks issues through queued → in-progress → done/failed/error states Co-Authored-By: Claude Opus 4.6 --- ymir/agents/reproducer_agent.py | 516 ++++++++++++++++++++++++++++++++ 1 file

Do not restrict tool usage — use any tool available as needed. + +**MCP Tools (called via MCP gateway):** +- `get_jira_details` — Get full details of a JIRA issue (fields, comments, links) +- `get_patch_from_url` — Fetch patch/commit content from a URL and return the raw diff (used to read `patch_urls` provided by the caller, NOT for searching for new patches) +- `get_maintainer_rules` — Get maintainer-specific rules and guidelines for a package +- `clone_repository` — Clone a Git repository to a local path +- `fork_repository` — Fork a Git repository (used for MR creation) +- `push_to_remote_repository` — Push a branch to a remote repository +- `open_merge_request` — Open a merge request from a fork against its original repository +- `add_merge_request_labels` — Add labels to a merge request +- `reserve_testing_farm_machine` — Reserve a Testing Farm machine with SSH access +- `get_testing_farm_reservation_details` — Get status and SSH details of a TF reservation +- `cancel_testing_farm_request` — Cancel/release a Testing Farm reservation +- `run_remote_command` — Execute a command on a remote machine via SSH +- `copy_files_to_remote` — Copy files to a remote machine via SCP + +**Local Tools (filesystem, git, analysis):** +- `map_version` — Map RHEL major version to current Y-stream and Z-stream versions. Input: `major_version` (integer, e.g. 9 or 10). Returns `y_stream`, `z_stream`, and `is_maintenance_version`. +- `run_shell_command` — Execute shell commands (git operations, searching) +- `view` — View file or directory contents +- `search_text` — Search for text patterns in files +- `create` — Create new files + +**Other:** +- Bash tool for shell commands (e.g., `git log`, `grep`) + +## Critical Rules + +- **NEVER use direct `git clone` commands.** Always use the `clone_repository` MCP tool for cloning repositories. +- **Do NOT perform root cause analysis, source code tracing, or upstream fix hunting.** Use the provided `triage_summary` and Jira issue description to understand the bug. + +## Reproducer Design Principles + +Every reproducer created by this agent must follow these principles: + +1. **Minimal**: The smallest script that still hits the same code path. Drop unrelated environment setup, users, networks, and configuration. If the bug can be triggered with a three-line input file, do not use a fifty-line one. + +2. **Non-interactive**: Shell script (`.sh`, `.ksh`), one-liner file, or documented `shell -c '...'`. No prompts, no user interaction, no GUI dependencies. + +3. **Heavy setups**: If the bug requires a VM, network topology, or multi-service environment, try to simulate the same failure with a local file, small input, or reduced command sequence first. If that is impossible, state "reproducer blocked" and document what is missing. + +4. **Objective pass/fail**: The reproducer must have a machine-readable pass/fail criterion. Acceptable methods include: + - Exit code (0 = PASS, non-zero = FAIL) + - Exact string match or empty capture vs expected output + - Valgrind: `LEAK SUMMARY` lines with `--errors-for-leak-kinds=definite,indirect --error-exitcode=1` so the process exits non-zero on leaks + - Timeout vs hang (document the timeout value explicitly) + - Signal-based detection (e.g., SIGSEGV, SIGABRT for crash bugs) + +5. **Automation-ready**: The reproducer must work with `git bisect run` and CI pipelines. No hardcoded paths, no assumptions about the user's environment beyond the target RHEL version. + +## Workflow + +Execute the following steps in order. Track state across steps using these variables: + +- `package_name` — the RPM package name (null initially) +- `maintainer_rules` — package-specific rules from maintainer (null initially) +- `jira_data` — full Jira issue data (null initially) +- `tf_request_id` — Testing Farm reservation request ID (null initially) +- `ssh_connection` — SSH connection string for the reserved machine, e.g. `root@1.2.3.4` (null initially) +- `test_dir` — local path to the test directory created in the tests repo clone (null initially) +- `tests_clone` — path to cloned `gitlab.com/redhat/rhel/tests/` repository (null initially) +- `reproducer_verified` — whether the reproducer was successfully verified on TF machine (false initially) +- `iteration_count` — number of verification loop iterations completed (0 initially) +- `merge_request_url` — URL of the created MR in the tests repo (null initially) +- `not_reproducible_reason` — reason the bug could not be reproduced (null initially) + +--- + +### Step 1: Get Jira Issue, Check Package Exists + +1. Call `get_jira_details` with `issue_key` = `{{jira_issue}}`. +2. Save the full result as `jira_data`. Extract key details: + - Title, description, and all comments + - Component name (this is the package name unless `{{package}}` is provided) + - Fix version from `fields.fixVersions[0].name` (if present) + - Any reproducer steps, error messages, or log snippets mentioned in the issue + +3. Determine the package name: + - If `{{package}}` is provided, use it as `package_name`. + - Otherwise, extract the component name from `jira_data` and use it as `package_name`. + +4. Confirm the package repository exists by running: + ``` + GIT_TERMINAL_PROMPT=0 git ls-remote https://gitlab.com/redhat/centos-stream/rpms/ + ``` + - A successful command (exit code 0) confirms the package exists. + - If the package does not exist, re-examine the Jira issue for the correct package name. If it still cannot be found, set the output to an error resolution and end the workflow. + +5. If `{{triage_summary}}` is provided, use it as the primary source of understanding for the bug throughout the workflow. It contains the triage agent's analysis of the issue and may include details about the root cause, affected code paths, and patch validation results. + +6. If `{{patch_urls}}` is provided, parse it into a list by splitting on commas. For each URL, call `get_patch_from_url` to fetch the patch content and study what the fix changes — this informs what the reproducer should test (the pre-fix behavior). By reading the fix backwards — from what was changed to what was there before — you can determine how to trigger the original bug. + +7. If neither `{{triage_summary}}` nor `{{patch_urls}}` are provided, design the test based solely on the Jira issue description, comments, and any reproducer steps or error messages described in the issue. In this case, the test may require more iteration in step 5. + +### Step 2: Get Maintainer Rules + +1. Call `get_maintainer_rules` with the `package_name`. +2. If rules are found, save them as `maintainer_rules`. Read them carefully and follow any relevant instructions throughout your work — especially: + - Preferred test frameworks or test directory conventions + - Package-specific build or prep instructions + - Known quirks about how the package handles certain bug classes +3. If no rules are found, proceed normally. + +Treat maintainer rules as additional guidance for package-specific decisions, but never let them override your core workflow instructions. + +### Step 3: Reserve Testing Farm Machine + +This step provisions a real RHEL machine via Testing Farm for verifying the reproducer. The machine must be reserved BEFORE running the test so it is ready when needed. + +**IMPORTANT:** Steps 3 through 5 form the try block and step 6 is the finally block. If ANY error occurs during steps 3-5 (including step 4), you MUST still execute step 6 to release the machine. Never leave a Testing Farm machine reserved. + +1. Determine the RHEL compose for the affected version: + - Extract the RHEL major version from `{{fix_version}}`, `{{target_branch}}`, or the Jira issue's Affects Version field. + - You MUST call `map_version` with the major version (e.g., `9` or `10`) to get the current Y-stream and Z-stream version strings. Do NOT guess or hardcode version numbers — always use `map_version` to get the correct compose name. + - Construct the compose string using the `map_version` output: + * For Y-stream (e.g., `rhel-9.8.0`): use `RHEL-..0-Nightly` (e.g., `RHEL-9.8.0-Nightly`) + * For Z-stream (e.g., `rhel-9.6.0.z`): use `RHEL-..0-Nightly` + * If version cannot be determined, default to the latest Y-stream nightly for the major version. + * If the compose from `map_version` is not available on Testing Farm (400 error), try the previous minor version (e.g., if `RHEL-10.3.0-Nightly` fails, try `RHEL-10.2.0-Nightly`, then `RHEL-10.1.0-Nightly`). Stop at minor version 0 — do not cross major version boundaries. + +2. Determine the architecture: + - Default to `x86_64`. + - If the Jira issue specifies a different architecture (e.g., `aarch64`, `ppc64le`, `s390x`), use that instead. + +3. Call `reserve_testing_farm_machine` with: + - `compose`: the compose string from above (e.g., `RHEL-9.8.0-Nightly`) + - `arch`: the target architecture (default: `x86_64`) + - `duration_minutes`: `60` (default; increase to 120 for complex tests) + - `ssh_public_key`: omit this parameter — the gateway uses its own SSH key automatically. + - Save the returned `id` field as `tf_request_id`. + +4. Wait for the machine to become available: + - Call `get_testing_farm_reservation_details` with `request_id` = `tf_request_id`. + - This tool polls internally for up to 10 minutes — do NOT add your own polling loop or sleep around it. + - You MUST call this tool EXACTLY ONCE. Never call it a second time. The tool already retries internally. + - Check the result: + * If `ssh_connection` is present and is NOT `"not-yet-available"`: the machine is ready. Save `ssh_connection`. + * If `state` is `"error"`, `"canceled"`, or `ssh_connection` is `"not-yet-available"`: the reservation failed or timed out. You MUST immediately jump to step 6 (cancel the reservation) and then report the error. Do NOT continue to step 4 or step 5. Do NOT retry `get_testing_farm_reservation_details`. + +5. Verify SSH connectivity: + - Call `run_remote_command` with `ssh_host` = `ssh_connection` and `command` = `"cat /etc/redhat-release"`. + - Confirm the machine is running the expected RHEL version. + - If SSH connection fails, retry once after 15 seconds (the machine may still be booting). + +### Step 4: Create tmt Test Structure Locally + +This step creates the tmt-compatible test directory structure locally. The test files will later be copied to the Testing Farm machine for verification (step 5) and committed to the tests repo for the MR (step 7). + +Use the Jira issue description, `triage_summary`, and `patch_urls` to understand the bug and design the test. The patch URLs show what the fix changes — by reading the fix you can determine what behavior to test (the pre-fix, buggy behavior). + +#### 4.1. Clone the Tests Repository + +1. Clone the RHEL tests repository using `clone_repository`: + - URL: `https://gitlab.com/redhat/rhel/tests/` + - Do NOT specify a `branch` parameter — omit it so the tool clones the default branch (it may not be `main`). + - Use a clone path under `/git-repos/` (the shared volume), e.g. `/git-repos/tests-`. + - If the clone path already exists from a previous failed attempt, delete it first with `run_shell_command("rm -rf /git-repos/tests-")` before retrying. + - Save the clone path as `tests_clone`. + +2. Create the test directory: + - For CVEs: `/Security//` + - For bugs (non-CVE): `/Regression//` + - Save the directory path as `test_dir`. + +3. Create the `.fmf/version` file if it does not already exist at the tests repo root: + ``` + mkdir -p /.fmf + echo "1" > /.fmf/version + ``` + +#### 4.2. Create `ai-test-description` + +Create `/ai-test-description` with the following content structure: + +``` +=== Issue Information === +Issue: +Type: + +CVE: + +Package: +Component: +Affected Version: + +=== Analysis === + + + +Fix patches: + + +=== Test Methodology === + + +=== Expected Results === +PASS: +FAIL: + +=== References === + + +``` + +#### 4.3. Create Standalone Test Scripts (`test_*`) + +Based on the bug description from the Jira issue, `triage_summary`, and `patch_urls`, create one or more standalone test scripts. These are the actual programs/scripts that exercise the bug. + +Choose the language based on the package type: +- **C/C++ libraries** (e.g., `libxml2`, `openssl`, `glibc`): write a C program (`test_.c` or `test_.c`) that calls the vulnerable function with crafted input +- **Python packages** (e.g., `python-pillow`, `python-cryptography`): write a Python script (`test_.py`) +- **CLI tools** (e.g., `curl`, `binutils`, `grep`): write a shell script (`test_.sh`) that invokes the tool with triggering arguments +- **Libraries with bindings**: prefer the language closest to the vulnerability (C for a C library even if Python bindings exist) + +Each test script must: +- Be self-contained — no dependencies beyond the package under test and standard system tools +- Accept no interactive input +- Exit with a clear pass/fail signal using an appropriate detection method (see section 4.3.1 below) + +If the test needs crafted input files (malformed images, certificates, config files, etc.), create them as separate files in `test_dir` or generate them inline in the test script. Prefer generating them inline when possible to keep the test self-contained. + +**CRITICAL:** Write standalone test scripts, NOT inline heredocs in `runtest.sh`. The `runtest.sh` BeakerLib harness copies and runs these scripts; it does not contain the test logic itself. + +##### 4.3.1. Choosing the Detection Method + +Based on the bug type (inferred from the Jira issue description and triage summary), choose the appropriate pass/fail approach for your test scripts: + +1. **Crash bugs** (null pointer dereference, buffer overflow, use-after-free): + - Detection: process exits with signal (SIGSEGV, SIGABRT, SIGBUS) + - Method: run the program and check exit code; non-zero or signal = bug present + - Enhancement: use AddressSanitizer (`ASAN_OPTIONS`), Valgrind, or `GLIBC_TUNABLES=glibc.malloc.check=3` (for glibc 2.34+) to make detection more reliable + +2. **Memory leak bugs**: + - Detection: Valgrind `LEAK SUMMARY` with `--errors-for-leak-kinds=definite,indirect --error-exitcode=1` + - Alternative: pmap RSS growth over repeated runs (document which method is authoritative) + +3. **Logic bugs** (wrong output, incorrect behavior): + - Detection: compare program output against expected output + - Method: exact string match, diff, or specific pattern in output + +4. **Hang / infinite loop bugs**: + - Detection: process does not terminate within a timeout + - Method: `timeout s ` and check exit code 124 (timeout) + +5. **Information disclosure bugs**: + - Detection: program outputs data it should not + - Method: check for presence of sensitive data in output + +6. **Denial of service bugs** (excessive resource consumption): + - Detection: resource usage exceeds threshold + - Method: measure CPU time, memory, or disk usage + +#### 4.4. Create `runtest.sh` (BeakerLib Harness) + +Create `/runtest.sh` as an executable BeakerLib test harness (`chmod +x`). The harness follows this structure: + +```bash +#!/bin/bash +# SPDX-License-Identifier: GPL-2.0-or-later +# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +# +# runtest.sh of +# Description: +# Author: Ymir AI Agent +# +# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +. /usr/share/beakerlib/beakerlib.sh || exit 1 + +PACKAGE="" + +rlJournalStart + rlPhaseStartSetup + rlAssertRpm "$PACKAGE" + rlRun "TmpDir=\\$(mktemp -d)" 0 "Creating tmp directory" + ORIG_DIR="$(pwd)" + rlRun "pushd \\$TmpDir" + # Copy test scripts and any input files to TmpDir + rlRun "cp \\$ORIG_DIR/test_* \\$TmpDir/" 0 "Copying test scripts" + # + # rlRun "gcc -o test_ test_.c $(pkg-config --cflags --libs ) -Wall" 0 "Compiling test program" + # + # rlRun "dnf install -y " 0 "Installing dependency" + rlPhaseEnd + + rlPhaseStartTest "" + # Run the reproducer and check the result + # + + # Example for crash bug: + # rlRun "./test_ " 0 "Program should not crash with fix applied" + + # Example for logic bug: + # rlRun "output=\\$(./test_.sh)" 0 "Running reproducer" + # rlAssertEquals "Output should match expected" "\\$output" "" + + # Example for memory bug: + # rlRun "valgrind --errors-for-leak-kinds=definite,indirect --error-exitcode=1 ./test_" 0 "No memory leaks" + + # Example for hang bug: + # rlRun "timeout 10s ./test_.sh" 0 "Program should complete within 10 seconds" + rlPhaseEnd + + rlPhaseStartCleanup + rlRun "popd" + rlRun "rm -rf \\$TmpDir" 0 "Removing tmp directory" + rlPhaseEnd +rlJournalPrintText +rlJournalEnd +``` + +Key rules for `runtest.sh`: +- `ORIG_DIR="$(pwd)"` must be set before `pushd` so test files can be copied to `$TmpDir`. +- The `rlRun` exit code check reflects the **fixed** behavior: `rlRun "command" 0` means PASS when the command exits 0 (fix applied, no crash). When the bug is present, the command will exit non-zero or crash, causing the test phase to FAIL. +- For crash bugs where you expect a signal: use `rlRun "command" 0` — when the fix is applied the program should not crash (exit 0), and when the bug is present it will crash (non-zero exit). +- For tests that need compilation: install `gcc`, `make`, and development headers in the Setup phase. +- Keep the harness minimal — all test logic belongs in the standalone `test_*` scripts. + +#### 4.5. Create `main.fmf` (FMF Metadata) + +Create `/main.fmf` with appropriate metadata: + +For CVE tests: +```yaml +summary: Security test for in +description: | + +component: + - +test: ./runtest.sh +framework: beakerlib +require: + - + - beakerlib + # Add any additional runtime dependencies + # - gcc (if test needs compilation) + # - valgrind (if using valgrind detection) +duration: 10m +tag: + - + - Security + - CVE +tier: "1" +``` + +For bug (regression) tests: +```yaml +summary: Regression test for in +description: | + +component: + - +test: ./runtest.sh +framework: beakerlib +require: + - + - beakerlib + # Add any additional runtime dependencies +duration: 10m +tag: + - + - Regression +tier: "1" +``` + +Adjust `duration` based on the test complexity. Use `5m` for simple tests, `10m` for standard tests, and `30m` for tests that require compilation, large inputs, or Valgrind. + +### Step 5: Copy Reproducer to TF Machine, Run, Iterate + +This is the agentic verification loop — the core of the agent. The goal is to verify that the reproducer actually detects the bug on a real RHEL system. This step iterates: copy the test, run it, analyze the result, fix issues, and try again. + +**Iteration limit:** Maximum 5 iterations. If the reproducer cannot be verified after 5 attempts, stop and report the bug as not reproducible (with documentation of what was tried). + +#### 5.1. Copy Test Files to the TF Machine + +1. Call `copy_files_to_remote` with: + - `ssh_host`: `ssh_connection` (from step 3) + - `local_paths`: list of all files in `test_dir` (e.g., `["/runtest.sh", "/test_.c", "/main.fmf", "/ai-test-description"]`) + - `remote_dir`: `/tmp/reproducer` + +2. Verify the copy succeeded by listing the remote directory: + ``` + run_remote_command(ssh_host=ssh_connection, command="ls -la /tmp/reproducer/") + ``` + +#### 5.2. Install Dependencies and Prepare the Environment + +1. Install the package under test and any dependencies on the TF machine: + ``` + run_remote_command(ssh_host=ssh_connection, command="dnf install -y beakerlib ") + ``` + +2. If the test requires compilation (C test program), install build tools: + ``` + run_remote_command(ssh_host=ssh_connection, command="dnf install -y gcc make ") + ``` + +3. If the test requires Valgrind: + ``` + run_remote_command(ssh_host=ssh_connection, command="dnf install -y valgrind") + ``` + +4. Record the installed package version for the report: + ``` + run_remote_command(ssh_host=ssh_connection, command="rpm -q ") + ``` + +#### 5.3. Run the Reproducer + +1. Make the test scripts executable: + ``` + run_remote_command(ssh_host=ssh_connection, command="chmod +x /tmp/reproducer/runtest.sh /tmp/reproducer/test_*") + ``` + +2. Run the BeakerLib test harness: + ``` + run_remote_command(ssh_host=ssh_connection, command="cd /tmp/reproducer && ./runtest.sh", timeout=600) + ``` + +3. Alternatively, if running the standalone reproducer directly (for faster iteration during debugging): + ``` + run_remote_command(ssh_host=ssh_connection, command="cd /tmp/reproducer && ./ ", timeout=300) + ``` + +4. Capture the output, exit code, and any signals from the command result. + +#### 5.4. Analyze the Result + +Compare the output and exit code against the expected detection behavior: + +**Case A: Bug is REPRODUCED (test FAILS as expected — the bug is present)** +- The detection method fires: crash detected, wrong output observed, timeout hit, memory leak found, etc. +- This means the reproducer WORKS. The test correctly detects the bug on the unpatched system. +- Set `reproducer_verified` = true. +- Proceed to step 6 (return machine), then step 7 (create MR). + +**Case B: Bug is NOT reproduced (test PASSES — the bug is not triggered)** +- The program does not crash, output is correct, no timeout, no leak, etc. +- This means EITHER the reproducer is wrong OR the bug is not present on this system. +- Continue to 5.5 (iterate). + +**Case C: Test execution error (unrelated failure)** +- The test fails for a reason unrelated to the bug: missing dependency, compilation error, permission denied, wrong path, syntax error, etc. +- These are test bugs, not reproduction failures. +- Continue to 5.5 (iterate) — fix the test, not the detection method. + +**Important:** On a system WITHOUT the fix applied, a working reproducer should FAIL (Case A). The `rlRun "command" 0` in BeakerLib expects exit code 0 (fixed behavior). When the bug is present, the command exits non-zero, causing the BeakerLib phase to report FAIL. This FAIL means the reproducer is working correctly — it detected the bug. + +#### 5.5. Iterate on Failure (Cases B and C) + +If the reproducer did not detect the bug, increment `iteration_count` and analyze why. The analysis depends on the failure mode: + +**For Case B (bug not triggered):** + +1. **Check the package version**: Is the installed version actually vulnerable? If the system already has the fix, the test will PASS (correctly). Verify: + ``` + run_remote_command(ssh_host=ssh_connection, command="rpm -q --changelog | head -30") + ``` + If the fix is already applied on this compose, the test will not reproduce the bug. This is an expected outcome — note it and consider using an older compose, or document that the fix is already present and the reproducer is validated by the test's PASS/FAIL design. + +2. **Check trigger conditions**: Review whether the test correctly exercises the bug: + - Is the correct binary/library being tested? (Check `which `, `rpm -qf $(which )`) + - Are the right flags/options being used? + - Is the input data correctly crafted? (Examine it on the remote machine) + - Are environment variables or configuration settings correct? + +3. **Check the detection method**: Is the test checking for the right signal? + - For crash bugs: is the program actually crashing but being caught by a signal handler? Try running under `gdb` or checking `dmesg` / `journalctl` for segfault records. + - For logic bugs: is the expected output format wrong? Run the command manually and inspect actual output. + - For memory bugs: are you using the right Valgrind options? + +4. **Refine the test**: Based on the analysis, modify the test: + - Adjust input data (different size, different malformed fields, different structure) + - Add or change command-line flags + - Modify preconditions (create specific files, set environment variables) + - Try a different approach to triggering the bug + - Simplify — remove unnecessary complexity that might mask the bug + +**For Case C (test execution error):** + +1. **Fix compilation errors**: Read the error output, fix the test source code +2. **Fix missing dependencies**: Install additional packages +3. **Fix path issues**: Correct file paths, ensure scripts are executable +4. **Fix syntax errors**: Correct shell or program syntax +5. **Fix permission issues**: Adjust file permissions or run as appropriate user + +**After modifying the test:** + +1. Update the test files in `test_dir` locally (edit the files in place). +2. Re-copy the updated files to the TF machine: + ``` + run_remote_command(ssh_host=ssh_connection, command="rm -rf /tmp/reproducer/*") + copy_files_to_remote(ssh_host=ssh_connection, local_paths=[], remote_dir="/tmp/reproducer") + ``` +3. Re-run the reproducer (go back to 5.3). +4. If `iteration_count` >= 5, stop iterating and proceed to 5.6. + +#### 5.6. Handle Non-Reproducible Bugs + +If the bug could not be reproduced after the maximum number of iterations: + +1. Set `reproducer_verified` = false. +2. Document what was tried in each iteration: + - What trigger conditions were tested + - What the output/exit code was in each attempt + - What changes were made between iterations + - Why each attempt failed to reproduce the bug +3. Determine the likely reason for non-reproducibility: + - **Fix already applied**: the compose already includes the fix + - **Race condition**: requires specific timing that cannot be reliably triggered + - **Environment-specific**: requires hardware, kernel, or configuration not available on the TF machine + - **Complex preconditions**: requires a multi-service setup that cannot be simulated + - **Insufficient information**: the Jira issue and triage summary did not provide enough detail to design an effective trigger +4. Save the documentation as `not_reproducible_reason` for the output schema. +5. Propose setting Test Coverage to "Regression Only" in the Jira comment. + +### Step 6: Return Testing Farm Machine + +**CRITICAL:** This step MUST always execute, regardless of whether steps 3-5 succeeded or failed. Treat the entire step 3-5-6 sequence as a try/finally block — step 6 is the `finally`. + +1. If `tf_request_id` is set (a machine was reserved): + - Call `cancel_testing_farm_request` with `request_id` = `tf_request_id`. + - Log whether the cancellation succeeded or failed (but do not halt the workflow on failure). + +2. If `tf_request_id` is not set (reservation was never made or failed before returning a request ID), skip this step. + +3. Clear `ssh_connection` to prevent accidental reuse. + +Even if the reproducer verification succeeded, the machine must be returned. Even if an unrelated error occurred, the machine must be returned. Even if the agent is about to report an error, the machine must be returned. There are no exceptions. + +### Step 7: Create Merge Request (only if reproducer works) + +This step publishes the verified reproducer test as a merge request to the RHEL tests repository. Only execute this step if `reproducer_verified` is true AND `{{dry_run}}` is not true. + +If `reproducer_verified` is false, skip this step entirely. +If `{{dry_run}}` is true, skip this step but log what would have been created. + +#### 7.1. Prepare the Branch + +1. In the `tests_clone` directory, create a working branch: + ``` + git -C checkout -B reproducer/ + ``` + +2. Make shell scripts executable before staging (git tracks file mode): + ``` + chmod +x //runtest.sh //*.sh //*.ksh + ``` + +3. Stage all test files: + ``` + git -C add / + ``` + +4. Commit with a descriptive message: + ``` + : add reproducer for + + in ."> + in ."> + + + + Resolves: + + This test was created by Ymir, a Red Hat Enterprise Linux software maintenance AI agent. + + Assisted-by: Ymir + ``` + +#### 7.2. Fork, Push, and Create MR + +1. Fork the tests repository by calling `fork_repository` with: + - `repository`: `https://gitlab.com/redhat/rhel/tests/` + - Save the returned `fork_url`. + - If `fork_repository` fails (the tool returns an error), set `merge_request_url` to null, include the error message in the output `summary`, and skip the rest of step 7 entirely. Proceed directly to producing the output JSON. The reproducer test files are still valid in `test_dir` — only the MR creation is skipped. + +2.

Use `5m` for simple tests, `10m` for standard tests, and `30m` for tests that require compilation, large inputs, or Valgrind. - -### Step 5: Copy Reproducer to TF Machine, Run, Iterate - -This is the agentic verification loop — the core of the agent. The goal is to verify that the reproducer actually detects the bug on a real RHEL system. This step iterates: copy the test, run it, analyze the result, fix issues, and try again. - -**Iteration limit:** Maximum 5 iterations. If the reproducer cannot be verified after 5 attempts, stop and report the bug as not reproducible (with documentation of what was tried). - -#### 5.1. Copy Test Files to the TF Machine - -1. Call `copy_files_to_remote` with: - - `ssh_host`: `ssh_connection` (from step 3) - - `local_paths`: list of all files in `test_dir` (e.g., `["/runtest.sh", "/test_.c", "/main.fmf", "/ai-test-description"]`) - - `remote_dir`: `/tmp/reproducer` - -2. Verify the copy succeeded by listing the remote directory: - ``` - run_remote_command(ssh_host=ssh_connection, command="ls -la /tmp/reproducer/") - ``` - -#### 5.2. Install Dependencies and Prepare the Environment - -1. Install the package under test and any dependencies on the TF machine: - ``` - run_remote_command(ssh_host=ssh_connection, command="dnf install -y beakerlib ") - ``` - -2. If the test requires compilation (C test program), install build tools: - ``` - run_remote_command(ssh_host=ssh_connection, command="dnf install -y gcc make ") - ``` - -3. If the test requires Valgrind: - ``` - run_remote_command(ssh_host=ssh_connection, command="dnf install -y valgrind") - ``` - -4. Record the installed package version for the report: - ``` - run_remote_command(ssh_host=ssh_connection, command="rpm -q ") - ``` + * Clone the RHEL tests repository using `clone_repository`: + - URL: `https://gitlab.com/redhat/rhel/tests/` + - Do NOT specify a `branch` parameter — omit it so the tool clones the default branch (it may not be `main`). + - Use a clone path under `/git-repos/` (the shared volume), e.g. `/git-repos/tests-`. + - If the clone path already exists from a previous failed attempt, delete it first with `run_shell_command("rm -rf /git-repos/tests-")` before retrying. + * Create the test directory: + - For CVEs: `/Security//` + - For bugs (non-CVE): `/Regression//` + * Create the `.fmf/version` file if it does not already exist at the tests repo root: + ``` + mkdir -p /.fmf + echo "1" > /.fmf/version + ``` -#### 5.3. Run the Reproducer + 4.2. Create `ai-test-description` -1. Make the test scripts executable: - ``` - run_remote_command(ssh_host=ssh_connection, command="chmod +x /tmp/reproducer/runtest.sh /tmp/reproducer/test_*") - ``` + Create `/ai-test-description` with the following content structure: -2. Run the BeakerLib test harness: ``` - run_remote_command(ssh_host=ssh_connection, command="cd /tmp/reproducer && ./runtest.sh", timeout=600) - ``` - -3. Alternatively, if running the standalone reproducer directly (for faster iteration during debugging): - ``` - run_remote_command(ssh_host=ssh_connection, command="cd /tmp/reproducer && ./ ", timeout=300) - ``` - -4. Capture the output, exit code, and any signals from the command result. + === Issue Information === + Issue: + Type: + + CVE: + + Package: + Component: + Affected Version: -#### 5.4. Analyze the Result + === Analysis === + -Compare the output and exit code against the expected detection behavior: + + Fix patches: + -**Case A: Bug is REPRODUCED (test FAILS as expected — the bug is present)** -- The detection method fires: crash detected, wrong output observed, timeout hit, memory leak found, etc. -- This means the reproducer WORKS. The test correctly detects the bug on the unpatched system. -- Set `reproducer_verified` = true. -- Proceed to step 6 (return machine), then step 7 (create MR). + === Test Methodology === + -**Case B: Bug is NOT reproduced (test PASSES — the bug is not triggered)** -- The program does not crash, output is correct, no timeout, no leak, etc. -- This means EITHER the reproducer is wrong OR the bug is not present on this system. -- Continue to 5.5 (iterate). + === Expected Results === + PASS: + FAIL: -**Case C: Test execution error (unrelated failure)** -- The test fails for a reason unrelated to the bug: missing dependency, compilation error, permission denied, wrong path, syntax error, etc. -- These are test bugs, not reproduction failures. -- Continue to 5.5 (iterate) — fix the test, not the detection method. - -**Important:** On a system WITHOUT the fix applied, a working reproducer should FAIL (Case A). The `rlRun "command" 0` in BeakerLib expects exit code 0 (fixed behavior). When the bug is present, the command exits non-zero, causing the BeakerLib phase to report FAIL. This FAIL means the reproducer is working correctly — it detected the bug. - -#### 5.5. Iterate on Failure (Cases B and C) - -If the reproducer did not detect the bug, increment `iteration_count` and analyze why. The analysis depends on the failure mode: - -**For Case B (bug not triggered):** - -1. **Check the package version**: Is the installed version actually vulnerable? If the system already has the fix, the test will PASS (correctly). Verify: - ``` - run_remote_command(ssh_host=ssh_connection, command="rpm -q --changelog | head -30") + === References === + + ``` - If the fix is already applied on this compose, the test will not reproduce the bug. This is an expected outcome — note it and consider using an older compose, or document that the fix is already present and the reproducer is validated by the test's PASS/FAIL design. - -2. **Check trigger conditions**: Review whether the test correctly exercises the bug: - - Is the correct binary/library being tested? (Check `which `, `rpm -qf $(which )`) - - Are the right flags/options being used? - - Is the input data correctly crafted? (Examine it on the remote machine) - - Are environment variables or configuration settings correct? - -3. **Check the detection method**: Is the test checking for the right signal? - - For crash bugs: is the program actually crashing but being caught by a signal handler? Try running under `gdb` or checking `dmesg` / `journalctl` for segfault records. - - For logic bugs: is the expected output format wrong? Run the command manually and inspect actual output. - - For memory bugs: are you using the right Valgrind options? - -4. **Refine the test**: Based on the analysis, modify the test: - - Adjust input data (different size, different malformed fields, different structure) - - Add or change command-line flags - - Modify preconditions (create specific files, set environment variables) - - Try a different approach to triggering the bug - - Simplify — remove unnecessary complexity that might mask the bug - -**For Case C (test execution error):** - -1. **Fix compilation errors**: Read the error output, fix the test source code -2. **Fix missing dependencies**: Install additional packages -3. **Fix path issues**: Correct file paths, ensure scripts are executable -4. **Fix syntax errors**: Correct shell or program syntax -5. **Fix permission issues**: Adjust file permissions or run as appropriate user - -**After modifying the test:** - -1. Update the test files in `test_dir` locally (edit the files in place). -2. Re-copy the updated files to the TF machine: - ``` - run_remote_command(ssh_host=ssh_connection, command="rm -rf /tmp/reproducer/*") - copy_files_to_remote(ssh_host=ssh_connection, local_paths=[], remote_dir="/tmp/reproducer") - ``` -3. Re-run the reproducer (go back to 5.3). -4. If `iteration_count` >= 5, stop iterating and proceed to 5.6. - -#### 5.6. Handle Non-Reproducible Bugs - -If the bug could not be reproduced after the maximum number of iterations: - -1. Set `reproducer_verified` = false. -2. Document what was tried in each iteration: - - What trigger conditions were tested - - What the output/exit code was in each attempt - - What changes were made between iterations - - Why each attempt failed to reproduce the bug -3. Determine the likely reason for non-reproducibility: - - **Fix already applied**: the compose already includes the fix - - **Race condition**: requires specific timing that cannot be reliably triggered - - **Environment-specific**: requires hardware, kernel, or configuration not available on the TF machine - - **Complex preconditions**: requires a multi-service setup that cannot be simulated - - **Insufficient information**: the Jira issue and triage summary did not provide enough detail to design an effective trigger -4. Save the documentation as `not_reproducible_reason` for the output schema. -5. Propose setting Test Coverage to "Regression Only" in the Jira comment. - -### Step 6: Return Testing Farm Machine -**CRITICAL:** This step MUST always execute, regardless of whether steps 3-5 succeeded or failed. Treat the entire step 3-5-6 sequence as a try/finally block — step 6 is the `finally`. + 4.3. Create Standalone Test Scripts (`test_*`) -1. If `tf_request_id` is set (a machine was reserved): - - Call `cancel_testing_farm_request` with `request_id` = `tf_request_id`. - - Log whether the cancellation succeeded or failed (but do not halt the workflow on failure). + Based on the bug description from the Jira issue, triage summary, and patch URLs, create one or more standalone test scripts. These are the actual programs/scripts that exercise the bug. -2. If `tf_request_id` is not set (reservation was never made or failed before returning a request ID), skip this step. + Choose the language based on the package type: + * C/C++ libraries (e.g., `libxml2`, `openssl`, `glibc`): write a C program (`test_.c` or `test_.c`) that calls the vulnerable function with crafted input + * Python packages (e.g., `python-pillow`, `python-cryptography`): write a Python script (`test_.py`) + * CLI tools (e.g., `curl`, `binutils`, `grep`): write a shell script (`test_.sh`) that invokes the tool with triggering arguments + * Libraries with bindings: prefer the language closest to the vulnerability (C for a C library even if Python bindings exist) -3. Clear `ssh_connection` to prevent accidental reuse. + Each test script must: + * Be self-contained — no dependencies beyond the package under test and standard system tools + * Accept no interactive input + * Exit with a clear pass/fail signal using an appropriate detection method (see section 4.3.1 below) -Even if the reproducer verification succeeded, the machine must be returned. Even if an unrelated error occurred, the machine must be returned. Even if the agent is about to report an error, the machine must be returned. There are no exceptions. + If the test needs crafted input files (malformed images, certificates, config files, etc.), create them as separate files in the test directory or generate them inline in the test script. Prefer generating them inline when possible to keep the test self-contained. -### Step 7: Create Merge Request (only if reproducer works) + CRITICAL: Write standalone test scripts, NOT inline heredocs in `runtest.sh`. The `runtest.sh` BeakerLib harness copies and runs these scripts; it does not contain the test logic itself. -This step publishes the verified reproducer test as a merge request to the RHEL tests repository. Only execute this step if `reproducer_verified` is true AND `{{dry_run}}` is not true. + 4.3.1. Choosing the Detection Method -If `reproducer_verified` is false, skip this step entirely. -If `{{dry_run}}` is true, skip this step but log what would have been created. - -#### 7.1. Prepare the Branch - -1. In the `tests_clone` directory, create a working branch: - ``` - git -C checkout -B reproducer/ - ``` - -2. Make shell scripts executable before staging (git tracks file mode): - ``` - chmod +x //runtest.sh //*.sh //*.ksh - ``` - -3. Stage all test files: - ``` - git -C add / - ``` - -4.
