* 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.

* 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.

Remove sshpubkeys from cloudstack extras to eliminate the vulnerable

role uses Ansible collection modules, not this Python package.
CVE-2024-23342 is a high severity Minerva timing attack affecting all

The Jinja2 template was building a string that looked like a list
instead of an actual list. When Ansible iterated over this string,
it yielded one character per iteration, causing the region prompt
to display:
1. [
2. '
3. a
...
Now follows the pattern used by other cloud providers (EC2, DigitalOcean,
etc.) by storing region objects directly and accessing .name property.

* 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
The firewall rules were being appended (-A) after existing DROP rules

- Server port listening status
- iptables INPUT chain on timeout (to verify rules)

* 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.

WireGuard only initiates a handshake when there's outgoing traffic or

Preparatory work for issue #14810 (stroke to swanctl migration).
This change adds AF_UNIX to the allowed socket address families in the
StrongSwan SystemD service hardening configuration. This is required for
the VICI socket (/var/run/charon.vici) that swanctl uses to communicate
with the charon daemon.
The change is:
- Backward-compatible (doesn't affect current stroke interface)
- Zero-risk (additive change only)
- Future-proof (enables eventual swanctl migration)
Full migration is deferred until Ubuntu 26.04 approaches, per research
findings documented in #14810.

* 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
