Using --locked alone provides the stricter enforcement we want -
it asserts the lockfile won't change and errors if it would.

* Fix critical certificate generation issues for macOS/iOS VPN compatibility
This commit addresses multiple certificate generation bugs in the Ansible crypto
module implementation that were causing VPN authentication failures on Apple devices.
Fixes implemented:
1. **Basic Constraints Extension**: Added missing `CA:FALSE` constraints to both
server and client certificate CSRs. This was causing certificate chain validation
errors on macOS/iOS devices.
2. **Subject Key Identifier**: Added `create_subject_key_identifier: true` to CA
certificate generation to enable proper Authority Key Identifier creation in
signed certificates.
3. **Complete Name Constraints**: Fixed missing DNS and IPv6 constraints in CA
certificate that were causing size differences compared to legacy shell-based
generation. Now includes:
- DNS constraints for the deployment-specific domain
- IPv6 permitted addresses when IPv6 support is enabled
- Complete IPv6 exclusion ranges (fc00::/7, fe80::/10, 2001:db8::/32)
These changes bring the certificate format much closer to the working shell-based
implementation and should resolve most macOS/iOS VPN connectivity issues.
**Outstanding Issue**: Authority Key Identifier still incomplete - missing DirName
and serial components. The community.crypto module limitation may require
additional investigation or alternative approaches.
Certificate size improvements: Server certificates increased from ~750 to ~775 bytes,
CA certificates from ~1070 to ~1250 bytes, bringing them closer to the expected
~3000 byte target size.

* Fix CI test failures in PKI certificate validation
Resolve Smart Test Selection workflow failures by fixing test validation logic:
**Certificate Configuration Fixes:**
- Remove unnecessary serverAuth/clientAuth EKUs from CA certificate
- CA now only has IPsec End Entity EKU for VPN-specific certificate issuance
- Maintains proper role separation between server and client certificates
**Test Validation Improvements:**
- Fix domain exclusion detection to handle both single and double quotes in YAML
- Improve EKU validation to check actual configuration lines, not comments
- Server/client certificate tests now correctly parse YAML structure
- Tests pass in both CI mode (config validation) and local mode (real certificates)
**Root Cause:**
The CI failures were caused by overly broad test assertions that:
1. Expected double-quoted strings but found single-quoted YAML
2. Detected EKU keywords in comments rather than actual configuration
3. Failed to properly parse YAML list structures
All security constraints remain intact - no actual security issues were present.
The certificate generation produces properly constrained certificates for VPN use.

* fix: Fix IPv6 address selection on BSD systems (#1843)
BSD systems return IPv6 addresses in the order they were added to the interface,
not sorted by scope like Linux. This causes ansible_default_ipv6 to contain
link-local addresses (fe80::) with interface suffixes (%em0) instead of global

- Filters out link-local addresses and interface suffixes
- Falls back to ansible_all_ipv6_addresses when needed

* Fix DigitalOcean cloud-init compatibility issue causing SSH timeout on port 4160
This commit addresses the issue described in GitHub issue #14800 where DigitalOcean
deployments fail during the "Wait until SSH becomes ready..." step due to cloud-init
not processing the write_files directive correctly.
## Problem
- DigitalOcean's cloud-init shows "Unhandled non-multipart (text/x-not-multipart) userdata" warning
- write_files module gets skipped, leaving SSH on default port 22 instead of port 4160
- Algo deployment times out when trying to connect to port 4160
## Solution
Added proactive detection and remediation to the DigitalOcean role:
1. Check if SSH is listening on the expected port (4160) after droplet creation
2. If not, automatically apply the SSH configuration manually via SSH on port 22
3. Verify SSH is now listening on the correct port before proceeding
## Changes
- Added SSH port check with 30-second timeout
- Added fallback remediation block that:
- Connects via SSH on port 22 to apply Algo's SSH configuration
- Backs up the original sshd_config
- Applies the correct SSH settings (port 4160, security hardening)
- Restarts the SSH service
- Verifies the fix worked
This ensures DigitalOcean deployments succeed even when cloud-init fails to process
the user_data correctly, maintaining backward compatibility and reliability.

* Implement cleaner fix for DigitalOcean cloud-init encoding issue
This replaces the previous workaround with two targeted fixes that address
the root cause of the "Unhandled non-multipart (text/x-not-multipart) userdata"
issue that prevents write_files from being processed.
## Root Cause
Cloud-init receives user_data as binary/bytes instead of UTF-8 string,
causing it to fail parsing and skip the write_files directive that
configures SSH on port 4160.
## Cleaner Solutions Implemented
### Fix 1: String Encoding (user_data | string)
- Added explicit string conversion to user_data template lookup
- Ensures DigitalOcean API receives proper UTF-8 string, not bytes
- Minimal change with maximum compatibility
### Fix 2: Use runcmd Instead of write_files
- Replaced write_files approach with runcmd shell commands
- Bypasses the cloud-init parsing issue entirely
- More reliable as it executes direct shell commands
- Includes automatic SSH config backup for safety
## Changes Made
- `roles/cloud-digitalocean/tasks/main.yml`: Added | string filter to user_data
- `files/cloud-init/base.yml`: Replaced write_files with runcmd approach
- Removed complex SSH detection/remediation workaround (no longer needed)
## Benefits
- ✅ Fixes root cause instead of working around symptoms
- ✅ Much simpler and more maintainable code
- ✅ Backward compatible - no API changes required
- ✅ Handles both potential failure modes (encoding + parsing)
- ✅ All tests pass, linters clean
This should resolve DigitalOcean SSH timeout issues while being much
cleaner than the previous workaround approach.

* Add comprehensive protection for cloud-config header format
- Add inline documentation explaining critical #cloud-config format requirement
- Exclude files/cloud-init/ from yamllint and ansible-lint to prevent automatic 'fixes'
- Create detailed README.md documenting the issue and protection measures
- Reference GitHub issue #14800 for future maintainers
This prevents regression of the critical cloud-init header format that
causes deployment failures when changed from '#cloud-config' to '# cloud-config'.

* Add test for cloud-init header format to prevent regression
This test ensures the cloud-init header remains exactly ''#cloud-config''
without a space. The regression in PR #14775 that added a space broke
DigitalOcean deployments by causing cloud-init YAML parsing to fail,
resulting in SSH timeouts on port 4160.

* Refactor SSH config template and fix MOTD task permissions
- Use dedicated sshd_config template instead of inline content
- Add explicit become: true to MOTD task to fix permissions warning

* Fix no_log variable references after renaming to algo_no_log
Update all remaining references from old 'no_log' variable to 'algo_no_log'
in WireGuard, SSH tunneling, and StrongSwan roles. This fixes deployment
failures caused by undefined variable references.

* fix: Correct YAML indentation in cloud-init template for DigitalOcean
The indent filter was not indenting the first line of the sshd_config content,
causing invalid YAML structure that cloud-init couldn't parse. This resulted
in SSH timeouts during deployment as the port was never changed from 22 to 4160.
- Add first=True parameter to indent filter to ensure all lines are indented
- Remove extra indentation in base template to prevent double-indentation
- Add comprehensive test suite to validate template rendering and prevent regressions
Fixes deployment failures where cloud-init would show:
"Invalid format at line X: expected <block end>, but found '<scalar>'"

* "Claude PR Assistant workflow"
* "Claude Code Review workflow"
* docs: Add CLAUDE.md for LLM guidance
This comprehensive guide captures important context and learnings for LLMs
working on the Algo VPN codebase, including:
- Project architecture and structure
- Critical dependencies and version management
- Development practices and code style
- Testing requirements and CI/CD pipeline
- Common issues and solutions
- Security considerations
- Platform support details
- Maintenance guidelines
The guide emphasizes Algo's core values: security, simplicity, and privacy.
It provides practical guidance based on extensive experience working with
the codebase, helping future contributors maintain high standards while
avoiding common pitfalls.
* feat: Configure Claude GitHub Actions with Algo-specific settings
- Add allowed_tools for running Ansible, Python, and shell linters
- Enable use_sticky_comment for cleaner PR discussions
- Add custom_instructions to follow Algo's security-first principles
- Reference CLAUDE.md for project-specific guidance
* chore: Conservative dependency updates for security
- Update Ansible from 9.1.0 to 9.2.0 (one minor version bump only)
- Update Jinja2 to ~3.1.6 to fix CVE-2025-27516 (critical security fix)
- Pin netaddr to 1.3.0 (current stable version)
This is a minimal, conservative update focused on:
1. Critical security fix for Jinja2
2. Minor ansible update for bug fixes
3. Pinning netaddr to prevent surprises
No changes to Ansible collections - keeping them unpinned for now.
* fix: Address linter issues (ruff, yamllint, shellcheck)
- Fixed ruff configuration by moving linter settings to [tool.ruff.lint] section
- Fixed ruff code issues:
- Moved imports to top of files (E402)
- Removed unused variables or commented them out
- Updated string formatting from % to .format()
- Replaced dict() calls with literals
- Fixed assert False usage in tests
- Fixed yamllint issues:
- Added missing newlines at end of files
- Removed trailing spaces
- Added document start markers (---) to YAML files
- Fixed 'on:' truthy warnings in GitHub workflows
- Fixed shellcheck issues:
- Properly quoted variables in shell scripts
- Fixed A && B || C pattern with proper if/then/else
- Improved FreeBSD rc script quoting
All linters now pass without errors related to our code changes.
* fix: Additional yamllint fixes for GitHub workflows
- Added document start markers (---) to test-effectiveness.yml
- Fixed 'on:' truthy warning by quoting as 'on:'
- Removed trailing spaces from main.yml
- Added missing newline at end of test-effectiveness.yml
This addresses the issue reported in PR #14173 where local installations
fail with 'sudo: a password is required' error. The sudo requirement is
now properly documented in the local installation guide rather than the
main README.
When installing Algo locally (on the same system where the scripts are
installed), administrative privileges are required to configure system
services and network settings.
* fix: Remove POSIX-incompatible 'local' keyword from install.sh
The install.sh script uses #\!/usr/bin/env sh (POSIX shell) but was using
the 'local' keyword in the tryGetMetadata function, which is a bash-specific
feature. This caused shellcheck to fail with SC3043 warnings in CI.
Fixed by removing 'local' keywords from variable declarations in the
tryGetMetadata function. The variables are still function-scoped in practice
since they're assigned at the beginning of the function.
This resolves the CI failure introduced in PR #14788 (run #919).
* ci: Make ansible-lint stricter and fix basic issues
- Remove || true from ansible-lint CI job to enforce linting
- Enable name[play] rule - all plays should be named
- Enable yaml[new-line-at-end-of-file] rule
- Move name[missing] from skip_list to warn_list (first step)
- Add names to plays in main.yml and users.yml
- Document future linting improvements in comments
This makes the CI stricter while fixing the easy issues first.
More comprehensive fixes for the 113 name[missing] warnings can
be addressed in future PRs.
* fix: Add name[missing] to skip_list temporarily
The ansible-lint CI is failing because name[missing] was not properly
added to skip_list. This causes 113 name[missing] errors to fail the CI.
Adding it to skip_list for now to fix the CI. The rule can be moved to
warn_list and eventually enabled once all tasks are properly named in
future PRs.
* fix: Fix ansible-lint critical errors
- Fix schema[tasks] error in roles/local/tasks/prompts.yml by removing with_items loop
- Add missing newline at end of requirements.yml
- Replace ignore_errors with failed_when in reboot task
- Add pipefail to shell command with pipes in strongswan openssl task
These fixes address all critical ansible-lint errors that were causing CI failures.
Added configurable timeouts and retry logic to all curl commands in publicIpFromMetadata():
- --connect-timeout 5: 5 seconds to establish connection
- --max-time ${METADATA_TIMEOUT:-20}: Configurable timeout (default 20 seconds)
- Retry logic: Try up to 2 times with 2-second delay between attempts
- Environment variable: METADATA_TIMEOUT can override default timeout
This prevents the installation script from hanging indefinitely when:
- Metadata services are slow or unresponsive
- Network issues cause connections to stall
- Script is run in non-cloud environments where metadata IPs don't respond
The increased timeout (20s) and retry logic ensure compatibility with:
- Azure deployments in secondary regions (known to be slower)
- High-latency environments (satellite, rural connections)
- Corporate environments with proxies or deep packet inspection
- Temporary network glitches or cloud provider maintenance
The existing fallback to publicIpFromInterface() will handle cases where
metadata endpoints are unavailable after all retry attempts.
