* 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.

* ci: add j2lint for Jinja2 template linting
Add j2lint (aristanetworks/j2lint) to catch syntax errors, spacing
issues, and operator formatting in Jinja2 templates. Integrated into
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.
Also fixes int+1 → int + 1 operator spacing in server.conf.j2.

* fix: resolve all ansible-lint warnings and enforce zero-tolerance policy
Fix 18 jinja[spacing] errors across 12 files by moving Jinja2 block
delimiters to prevent YAML >- folding from introducing trailing spaces.
Fix 27 key-order[task] warnings across 17 files by reordering task keys
to canonical order (name → when → tags → environment → become → block).
Promote key-order[task] and yaml[line-length] from warn_list to hard
errors by removing warn_list entirely from .ansible-lint.
Add zero-tolerance warning policy to CLAUDE.md explaining why warnings
are unacceptable in a security tool and documenting resolution order.

* 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:
- "{{ users }}" # ['alice', 'bob'] treated as ONE item
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

* Fix VPN routing by adding output interface to NAT rules
The NAT rules were missing the output interface specification (-o eth0),
which caused routing failures on multi-homed systems (servers with multiple
network interfaces). Without specifying the output interface, packets might
not be NAT'd correctly.
Changes:
- Added -o {{ ansible_default_ipv4['interface'] }} to all NAT rules
- Updated both IPv4 and IPv6 templates
- Updated tests to verify output interface is present
- Added ansible_default_ipv4/ipv6 to test fixtures
This fixes the issue where VPN clients could connect but not route traffic
to the internet on servers with multiple network interfaces (like DigitalOcean
droplets with private networking enabled).

* Fix VPN routing by adding output interface to NAT rules
On multi-homed systems (servers with multiple network interfaces or multiple IPs
on one interface), MASQUERADE rules need to specify which interface to use for
NAT. Without the output interface specification, packets may not be routed correctly.
This fix adds the output interface to all NAT rules:
-A POSTROUTING -s [vpn_subnet] -o eth0 -j MASQUERADE
Changes:
- Modified roles/common/templates/rules.v4.j2 to include output interface
- Modified roles/common/templates/rules.v6.j2 for IPv6 support
- Added tests to verify output interface is present in NAT rules
- Added ansible_default_ipv4/ipv6 variables to test fixtures
For deployments on providers like DigitalOcean where MASQUERADE still fails
due to multiple IPs on the same interface, users can enable the existing
alternative_ingress_ip option in config.cfg to use explicit SNAT.
Testing:
- Verified on live servers
- All unit tests pass (67/67)
- Mutation testing confirms test coverage
This fixes VPN connectivity on servers with multiple interfaces while
remaining backward compatible with single-interface deployments.

* Fix dnscrypt-proxy not listening on VPN service IPs
Problem: dnscrypt-proxy on Ubuntu uses systemd socket activation by default,
which overrides the configured listen_addresses in dnscrypt-proxy.toml.
The socket only listens on 127.0.2.1:53, preventing VPN clients from
resolving DNS queries through the configured service IPs.
Solution: Disable and mask the dnscrypt-proxy.socket unit to allow
dnscrypt-proxy to bind directly to the VPN service IPs specified in
its configuration file.
This fixes DNS resolution for VPN clients on Ubuntu 20.04+ systems.

* Restrict DNS access to VPN clients only
Security fix: The firewall rule for DNS was accepting traffic from any
source (0.0.0.0/0) to the local DNS resolver. While the service IP is
on the loopback interface (which normally isn't routable externally),
this could be a security risk if misconfigured.
Changed firewall rules to only accept DNS traffic from VPN subnets:
- INPUT rule now includes -s {{ subnets }} to restrict source IPs
- Applied to both IPv4 and IPv6 rules
- Added test to verify DNS is properly restricted
This ensures the DNS resolver is only accessible to connected VPN
clients, not the entire internet.

* Fix dnscrypt-proxy service startup with masked socket
Problem: dnscrypt-proxy.service has a dependency on dnscrypt-proxy.socket
through the TriggeredBy directive. When we mask the socket before starting
the service, systemd fails with "Unit dnscrypt-proxy.socket is masked."
Solution:
1. Override the service to remove socket dependency (TriggeredBy=)
2. Reload systemd daemon immediately after override changes
3. Start the service (which now doesn't require the socket)
4. Only then disable and mask the socket
This ensures dnscrypt-proxy can bind directly to the configured IPs
without socket activation, while preventing the socket from being
re-enabled by package updates.
Changes:
- Added TriggeredBy= override to remove socket dependency
- Added explicit daemon reload after service overrides
- Moved socket masking to after service start in main.yml
- Fixed YAML formatting issues

* Use systemd socket activation properly for dnscrypt-proxy
Instead of fighting systemd socket activation, configure it to listen
on the correct VPN service IPs. This is more systemd-native and reliable.
Changes:
- Create socket override to listen on VPN IPs instead of localhost
- Clear default listeners and add VPN service IPs
- Use empty listen_addresses in dnscrypt-proxy.toml for socket activation
- Keep socket enabled and let systemd manage the activation
- Add handler for restarting socket when config changes
Benefits:
- Works WITH systemd instead of against it
- Survives package updates better
- No dependency conflicts
- More reliable service management
This approach is cleaner than disabling socket activation entirely and
ensures dnscrypt-proxy is accessible to VPN clients on the correct IPs.

* Fix DNS resolution for VPN clients by enabling route_localnet
The issue was that dnscrypt-proxy listens on a special loopback IP
(randomly generated in 172.16.0.0/12 range) which wasn't accessible
from VPN clients. This fix:
1. Enables net.ipv4.conf.all.route_localnet sysctl to allow routing
to loopback IPs from other interfaces
2. Ensures dnscrypt-proxy socket is properly restarted when its
configuration changes
3. Adds proper handler flushing after socket configuration updates
This allows VPN clients to reach the DNS resolver at the local_service_ip
address configured on the loopback interface.

* Improve security by using interface-specific route_localnet
Instead of enabling route_localnet globally (net.ipv4.conf.all.route_localnet),
this change enables it only on the specific interfaces that need it:
- WireGuard interface (wg0) for WireGuard VPN clients
- Main network interface (eth0/etc) for IPsec VPN clients
This minimizes the security impact by restricting loopback routing to only
the VPN interfaces, preventing other interfaces from being able to route
to loopback addresses.
The interface-specific approach provides the same functionality (allowing
VPN clients to reach the DNS resolver on the local_service_ip) while
reducing the potential attack surface.

* Revert to global route_localnet to fix deployment failure
The interface-specific route_localnet approach failed because:
- WireGuard interface (wg0) doesn't exist until the service starts
- We were trying to set the sysctl before the interface was created
- This caused deployment failures with "No such file or directory"
Reverting to the global setting (net.ipv4.conf.all.route_localnet=1) because:
- It always works regardless of interface creation timing
- VPN users are trusted (they have our credentials)
- Firewall rules still restrict access to only port 53
- The security benefit of interface-specific settings is minimal
- The added complexity isn't worth the marginal security improvement
This ensures reliable deployments while maintaining the DNS resolution fix.

* Fix dnscrypt-proxy socket restart and remove problematic BPF hardening
Two important fixes:
1. Fix dnscrypt-proxy socket not restarting with new configuration
- The socket wasn't properly restarting when its override config changed
- This caused DNS to listen on wrong IP (127.0.2.1 instead of local_service_ip)
- Now directly restart the socket when configuration changes
- Add explicit daemon reload before restarting
2. Remove BPF JIT hardening that causes deployment errors
- The net.core.bpf_jit_enable sysctl isn't available on all kernels
- It was causing "Invalid argument" errors during deployment
- This was optional security hardening with minimal benefit
- Removing it eliminates deployment errors for most users
These fixes ensure reliable DNS resolution for VPN clients and clean

* 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.

* Fix cloud-init header format for DigitalOcean compatibility
The space in '# cloud-config' (introduced in PR #14775) breaks cloud-init
YAML parsing on DigitalOcean, causing SSH configuration to be skipped.
Cloud-init documentation requires '#cloud-config' without a space.

* Revert to write_files approach for SSH configuration
Using write_files is more maintainable and Ansible-native than runcmd.
The root cause was the cloud-config header format, not write_files itself.

* Fix Ansible deprecation and variable warnings
- Replace deprecated network filters with ansible.utils equivalents:
- ipaddr → ansible.utils.ipaddr
- ipmath → ansible.utils.ipmath
- ipv4 → ansible.utils.ipv4
- ipv6 → ansible.utils.ipv6
- next_nth_usable → ansible.utils.next_nth_usable
- Fix reserved variable name: no_log → algo_no_log
- Fix SSH user groups warning by explicitly specifying groups parameter
Addresses deprecation warnings that would become errors after 2024-01-01.
All linter checks pass with only cosmetic warnings remaining.

* 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.

* 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>'"

* 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.
With preexisting wait_for implementation, deployment to Ubuntu on Lightsail failed with a connection reset error on this task. It appears that Ansible’s wait_for_connection is the recommended way. I have successfully gotten past this task after this change, however I’d appreciate more eyes on this.
