Add pre-flight check in main.yml that catches missing cryptography/SECP384R1
before deployment starts, replacing the cryptic error from community.crypto
internals with an actionable message pointing users to run ./algo or uv sync.
Root cause of the CI ipsec/both test failures: cryptography 46.0.5 wraps
the ec module with _ModuleWithDeprecations (for SECT curve deprecation),
which breaks community.crypto's ec.__dict__.get("SECP384R1") lookup.
The fix in community.crypto 3.1.1 uses getattr() instead.
Changes:
- Add SECP384R1 pre-flight check to main.yml (conditional on ipsec_enabled)
- Add cryptography>=42.0.0 as explicit dependency in pyproject.toml
- Upgrade community.crypto to >=3.1.1 (fixes __dict__ vs getattr bug)
- Add ansible-galaxy collection install step to CI
- Use venv Python interpreter for local deployments in add_host tasks

* ci: add semgrep SAST scanning to CI and pre-commit
Add semgrep static analysis to the security workflow and pre-commit
hooks. Uses `--config auto` for comprehensive coverage across Python,
Dockerfile, and GitHub Actions. The intentional `USER root` in the
Dockerfile (required for bind mount compatibility) is excluded via
`--exclude-rule`.

* fix: add explicit bool filters for Ansible 12 jinja2_native compatibility
Ansible 12 enables jinja2_native by default, which means string values
like "true"/"false" are no longer automatically coerced to booleans in
when: conditions and Jinja2 if statements. Add | bool filters to all
boolean variable references in tasks, templates, and handlers.
Also reformats long single-line Jinja2 conditionals into multi-line for
readability, fixes GCE default() calls for native mode, adds help
command to the algo script, and updates test fixtures to register the
bool filter.

pre-commit hooks, lint.yml CI, and smart-tests.yml.
Rules S3/S5/S6/S7/V1 are ignored — they enforce conventions
incompatible with Ansible's config-file-embedded templates.

* Add end-to-end VPN connectivity tests using network namespaces
Addresses #14912
Current integration tests verify that VPN services start, but don't verify
they actually work. This adds true E2E tests using Linux network namespaces
to simulate a client connecting to the server.
New tests verify:
- WireGuard handshake completes and tunnel is functional
- IPsec/StrongSwan service is configured and listening
- DNS resolution works through VPN (172.16.0.1)
- mobileconfig XML files are valid
- CA certificate chain is correct
Changes:
- Add tests/e2e/test-vpn-connectivity.sh - main E2E test script
- Add tests/e2e/README.md - documentation for running tests
- Update integration-tests.yml to run E2E tests after deployment
- Delete tests/legacy-lxd/ - replaced by new E2E tests
- Update .ansible-lint to remove legacy-lxd from excludes
- Rewrite tests/README.md for clarity

* Fix WireGuard handshake timeout by allowing VPN traffic on veth
The namespace test was timing out because the firewall was blocking
UDP traffic on the veth interface. This adds explicit INPUT rules
to allow WireGuard (51820) and IPsec (500, 4500) traffic.
Also refines the MASQUERADE rule to not apply to bridge-local traffic.

* Use -I instead of -A for iptables rules; add debug output

* Work around deployment bug where WireGuard handlers don't fire
The async role execution in server.yml causes handlers not to fire
properly. This workaround restarts WireGuard if no peers are found,
ensuring the peer configuration is loaded.
Root cause: import_role with async: 300, poll: 0 breaks handler
notification flow. The 'restart wireguard' handler is notified but
never executed because the async context loses track of handlers.

* Fix Docker --cap-drop=all and add multi-arch support
Fixes#14899
## Bug Fix: CAP_DROP_ALL Permission Denied
The `chown -R algo:algo /algo` line added in commit 2ab57c3 broke
`--cap-drop=all` functionality. When running as root with all
capabilities dropped, root loses CAP_DAC_OVERRIDE and cannot write
to files owned by other users.
The fix removes the unnecessary chown since:
- Container runs as USER root
- algo-docker.sh writes to /algo/config.cfg at runtime
- /algo must be root-owned for --cap-drop=all to work
## Multi-arch Support
The Docker image was only built for linux/amd64. Added:
- QEMU setup for ARM emulation
- Docker Buildx for multi-platform builds
- platforms: linux/amd64,linux/arm64
This enables native support for Apple Silicon Macs.

* Fix with_items to loop conversion: preserve list flattening
with_items automatically flattens nested lists, but loop does NOT.
The mechanical conversion broke iteration over list variables.
Wrong:
loop:

Fixed:
loop: "{{ users }}" # Iterates over alice, bob correctly
For combined lists (users + server):
loop: "{{ users + [IP_subject_alt_name] }}"

* Fix ansible-lint failures and improve linting configuration
This PR eliminates all ansible-lint failures (9 → 0) and reduces warnings
(25 → 20). The remaining warnings are yaml[line-length] which are
intentionally in the warn_list.
Changes:
1. GitHub workflow YAML compliance
- Add document start markers (---)
- Quote 'on:' key (YAML truthy value)
2. Replace ignore_errors with failed_when
- privacy/clear_history.yml: Use failed_when: false instead of
ignore_errors for tasks that may fail on clean systems
3. Use apt module instead of shell
- privacy/auto_cleanup.yml: Replace apt-get shell command with
proper apt module (autoclean: true)
4. Add changed_when to handlers and tasks
- Handlers always run due to notifications, so changed_when: false
is appropriate for read-only operations
- Check commands that only read state get changed_when: false
- Reboot task gets changed_when: true (it actually changes state)
5. Configure ansible-lint for project structure
- Exclude CloudFormation templates (roles/cloud-*/files/) which use
AWS-specific YAML tags (!Equals, !GetAtt) that ansible-lint
cannot parse
- Add mock_modules for custom modules in library/ directory that
ansible-lint cannot auto-discover during static analysis

* Implement self-bootstrapping uv setup to resolve issue #14776
This major simplification addresses the Python setup complexity that
has been a barrier for non-developer users deploying Algo VPN.
## Revolutionary User Experience Change
**Before (complex):**
```bash
python3 -m virtualenv --python="$(command -v python3)" .env &&
source .env/bin/activate &&
python3 -m pip install -U pip virtualenv &&
python3 -m pip install -r requirements.txt
./algo
```
**After (simple):**
```bash
./algo
```
## Key Technical Changes
### Core Implementation
- **algo script**: Complete rewrite with automatic uv installation
- Detects missing uv and installs automatically via curl
- Cross-platform support (macOS, Linux, Windows)
- Preserves exact same command interface
- Uses `uv run ansible-playbook` instead of virtualenv activation
### Documentation Overhaul
- **README.md**: Reduced installation from 4 complex steps to 1 command
- **Platform docs**: Simplified macOS, Windows, Linux, Cloud Shell guides
- **Removed Python installation complexity** from all user-facing docs
### CI/CD Infrastructure Updates
- **5 GitHub Actions workflows** converted from pip to uv
- **Docker builds** updated to use uv instead of virtualenv
- **Legacy test scripts** (3 files) updated for uv compatibility
### Repository Cleanup
- **install.sh**: Updated for cloud-init/bootstrap scenarios
- **algo-showenv.sh**: Updated environment detection for uv
- **pyproject.toml**: Added all dependencies with proper versioning
- **test scripts**: Removed .env references, updated paths
## Benefits Achieved
✅ **Zero-step dependency installation** - uv installs automatically on first run
✅ **Cross-platform consistency** - identical experience on all operating systems
✅ **Automatic Python version management** - uv handles Python 3.11+ requirement
✅ **Familiar interface preserved** - existing `./algo` and `./algo update-users` unchanged
✅ **No breaking changes** - existing users see same commands, same functionality
✅ **Resolves macOS Python compatibility** - works with system Python 3.9 via uv's Python management
## Files Changed (18 total)
**Core Scripts (3)**:

* Fix linting and syntax errors caused by FreeBSD removal
- Restore missing newline in roles/dns/handlers/main.yml (broken during FreeBSD cleanup)
- Add FQCN for community.crypto modules in cloud-pre.yml
- Exclude playbooks/ directory from ansible-lint (these are task files, not standalone playbooks)
The FreeBSD removal accidentally removed a trailing newline causing YAML format errors.
The playbook syntax errors were false positives - these files contain tasks for
import_tasks/include_tasks, not standalone plays.

* Fix CI test failure: use uv-managed ansible in test script
The test script was calling ansible-playbook directly instead of 'uv run ansible-playbook',
which caused it to use the system-installed ansible that doesn't have access to the
netaddr dependency required by the ansible.utils.ipmath filter.
This fixes the CI error: 'Failed to import the required Python library (netaddr)'

* Remove unused uv installation code from PowerShell script
The PowerShell script is purely a WSL wrapper - it doesn't need to
install uv since it just passes execution to WSL/bash where the Unix
algo script handles dependency management. Removing dead code that

* Improve uv installation feedback and Docker dependency locking
- Track and display which installation method succeeded for uv
- Add --locked flag to Docker uv sync for stricter dependency enforcement
- Users now see "uv installed successfully via Homebrew\!" etc.
This addresses code review feedback about installation transparency
and dependency management strictness.

* Fix Docker build: use --locked without --frozen
The --frozen and --locked flags are mutually exclusive in uv.
Using --locked alone provides the stricter enforcement we want -
it asserts the lockfile won't change and errors if it would.

* Fix setuptools package discovery error during cloud provider dependency installation
The issue occurred when uv tried to install optional dependencies (e.g., [digitalocean])
because setuptools was auto-discovering directories like 'roles', 'library', etc. as
Python packages. Since Algo is an Ansible project, not a Python package, this caused
builds to fail.
Added explicit build-system configuration to pyproject.toml with py-modules = [] to
disable package discovery entirely.

* Fix Jinja2 template syntax error in OpenSSL certificate generation
Removed inline comments from within Jinja2 expressions in the name_constraints_permitted
and name_constraints_excluded fields. Jinja2 doesn't support comments within expressions
using the # character, which was causing template rendering to fail.
Moved explanatory comments outside the Jinja2 expressions to maintain documentation
while fixing the syntax error.

* Enhance Jinja2 template testing infrastructure
Added comprehensive Jinja2 template testing to catch syntax errors early:
1. Created validate_jinja2_templates.py:
- Validates all Jinja2 templates for syntax errors
- Detects inline comments in Jinja2 expressions (the bug we just fixed)
- Checks for common anti-patterns
- Provides warnings for style issues
- Skips templates requiring Ansible runtime context
2. Created test_strongswan_templates.py:
- Tests all StrongSwan templates with multiple scenarios
- Tests with IPv4-only, IPv6, DNS hostnames, and legacy OpenSSL
- Validates template output correctness
- Skips mobileconfig test that requires complex Ansible runtime
3. Updated .ansible-lint:
- Enabled jinja[invalid] and jinja[spacing] rules
- These will catch template errors during linting
4. Added scripts/test-templates.sh:
- Comprehensive test script that runs all template tests
- Can be used in CI and locally for validation
- All tests pass cleanly without false failures
- Treats spacing issues as warnings, not failures
This testing would have caught the inline comment issue in the OpenSSL
template before it reached production. All tests now pass cleanly.

* Fix StrongSwan CRL reread handler race condition
The ipsec rereadcrls command was failing with exit code 7 when the IPsec
daemon wasn't fully started yet. This is a timing issue that can occur
during initial setup.
Added retry logic to:
1. Wait up to 10 seconds for the IPsec daemon to be ready
2. Check daemon status before attempting CRL operations
3. Gracefully handle the case where daemon isn't ready
Also fixed Python linting issues (whitespace) in test files caught by ruff.

* Fix StrongSwan CRL handler properly without ignoring errors
Instead of ignoring errors (anti-pattern), this fix properly handles the race
condition when StrongSwan restarts:
1. After restarting StrongSwan, wait for port 500 (IKE) to be listening
- This ensures the daemon is fully ready before proceeding
- Waits up to 30 seconds with proper timeout handling
2. When reloading CRLs, use Ansible's retry mechanism
- Retries up to 3 times with 2-second delays
- Handles transient failures during startup
3. Separated rereadcrls and purgecrls into distinct tasks
- Better error reporting and debugging
- Cleaner task organization
This approach ensures the installation works reliably on fresh installs
without hiding potential real errors.

* Fix StrongSwan handlers - handlers cannot be blocks
Ansible handlers cannot be blocks. Fixed by:
1. Making each handler a separate task that can notify the next handler
2. restart strongswan -> notifies -> wait for strongswan
3. rereadcrls -> notifies -> purgecrls
This maintains the proper execution order while conforming to Ansible's
handler constraints. The wait and retry logic is preserved.

* Fix StrongSwan CRL handler for fresh installs
The root cause: rereadcrls handler is notified when copying CRL files
during certificate generation, which happens BEFORE StrongSwan is installed
and started on fresh installs.
The fix:
1. Check if StrongSwan service is actually running before attempting CRL reload
2. If not running, skip reload (not needed - StrongSwan will load CRLs on start)
3. If running, attempt reload with retries
This handles both scenarios:
- Fresh install: StrongSwan not yet running, skip reload
- Updates: StrongSwan running, reload CRLs properly
Also removed the wait_for port 500 which was failing because StrongSwan
doesn't bind to localhost.
