CrowdSec's host-side install (the agent + nftables bouncer the LibrePortal
Traefik plugin talks to) had stayed on blanket sudo throughout the rootless +
de-sudo hardening: `sudo apt-get install crowdsec`, `curl | sudo bash`,
`sudo sed -i /etc/crowdsec/config.yaml`, `sudo touch + sudo chmod /var/log/
crowdsec*.log`, `echo $key | sudo tee /etc/crowdsec/traefik_bouncer.key`,
plus `sudo cscli capi register / console enroll / bouncers add`. None of
those are in the scoped LP_HELPERS / LP_SYSTEM sudoers grant the manager
now holds, so any user who enabled crowdsec would have hit hard sudo
failures on every privileged step.
Follow the libreportal-appcfg / libreportal-bininstall pattern: one new
root-owned helper at /usr/local/lib/libreportal/libreportal-crowdsec
that does every privileged op behind a fixed action vocabulary with strict
argument validation. The manager calls in via runCrowdsec — the scoped
sudoers grants exactly one binary, the same trust boundary the other
helpers rely on.
Actions:
install apt repo + agent + firewall-bouncer + enable +
crowdsecurity/{linux,sshd} collections + reload
(idempotent — skips parts already in place)
services <verb> enable | disable | restart
capi <verb> register | unregister | status
console <verb> enroll <token> | disenroll | status
token format strictly validated
bouncer-traefik-init cscli register + write the manager-owned key file
atomically (returns EXISTS or GENERATED:<key>)
bouncer-priority bouncer yaml nftables priority → -100
(moved from libreportal-appcfg; one helper for
every crowdsec root op)
bind-lapi flip listen_uri to 0.0.0.0:8080 in config.yaml
prometheus <on…|off> flip the prometheus block (validated addr/port)
touch-host-logs create + chmod 0644 /var/log/crowdsec*.log so the
libreportal container can tail them
Wired in via:
- new sudoers Cmnd_Alias entry for the helper in LP_HELPERS
- new helper baked alongside the others by initRootHelpers
(replaces __SYSTEM_DIR__ / __CONTAINERS_DIR__ / __MANAGER__ at
install, with safe runtime fallbacks if unbaked)
- new runCrowdsec dispatch in scripts/docker/command/run_privileged.sh
containers/crowdsec/scripts/crowdsec_install_host.sh now drives the whole
flow through runCrowdsec — every `sudo …` is gone, the compose-toggle sed
uses runFileOp, and the security_crowdsec CFG mirror uses runInstallOp
(configs/ is manager-owned). Net: install script shrinks ~80 lines while
gaining a single auditable trust boundary. crowdsec_fix_priority.sh swung
over to runCrowdsec bouncer-priority too — the appcfg crowdsec_priority
action drops out cleanly.

The standalone WireGuard install used to flip net.ipv4.ip_forward by
appending+uncommenting `/etc/sysctl/99-custom.conf` via blanket sudo
(sudo tee, sudo sed, sudo sysctl -p). Two problems with that on a
de-sudoed manager:
- The path is non-standard. The conventional location is
/etc/sysctl.d/*.conf (drop-ins, loaded by sysctl --system) — the
old file may not even exist, leaving forwarding silently off.
- `sudo tee /etc` and `sudo sed -i /etc` are not in LP_SYSTEM. The
manager has lost the broad sudo it once had, so this would now
fail outright on every wireguard install.
Add a `wireguard-ip-forward` action to libreportal-appcfg that:
- writes /etc/sysctl.d/99-libreportal-wireguard.conf (a drop-in we
own and rewrite idempotently), and
- reloads via `sysctl --system` (with a `sysctl -p <dropin>` fallback).
containers/wireguard/wireguard.sh now calls `runAppCfg wireguard-ip-forward`
through the existing helper-dispatch path — the whole edit runs as root
in one validated step, no `sudo` in the per-app script.
Same de-sudo pattern as adguard-auth / crowdsec-priority / owncloud-config
already use.

The rename was justified partly by an anticipated second `libreportal-regen`
unit — which we then decided not to create (the poll rides the existing task
processor). What's left is cosmetic, and it isn't worth a footprint_version bump
(which forces a root re-install on every existing box) plus the dual-name
migration cruft.
Reverting also means the rename was the ONLY footprint change in the regen work,
so the whole regen system now ships as a plain manager-owned code deploy — no
root re-install needed. footprint_version stays 2.
Kept only the accurate FOOTPRINT.md note that the service also drives the poll.

The single systemd unit is the task processor (and now also drives the periodic
regen poll), so name it for what it does instead of the ambiguous bare
"libreportal.service" — clearer now that the runtime has more than one concern.
- svc helper: SERVICE_NAME=libreportal-taskprocessor.service; _drop_legacy()
stops/removes the pre-rename unit on install (idempotent migration) so an
upgraded box never runs two processors.
- init.sh: read baked roots from the new unit (fall back to the old name);
uninstall removes both names; bump footprint_version 2 -> 3 (root-owned unit
changed, so a manager-run update flags "root re-install needed").
- check_webui_systemd: accept either name during the transition.
- docs/FOOTPRINT.md: new unit name + uninstall command.
No sudoers change — it allows /usr/bin/systemctl generically, not a named unit.

sudo_user_name (the real manager — owns the install, runs the runtime, baked as
__MANAGER__ into the root helpers) was hardcoded to 'libreportal'. Make it
configurable, consistent with the relocatable roots:
- --manager-user=NAME flag + LP_MANAGER_USER env (default libreportal); resolved
early in init.sh and in scripts/source/paths.sh (so the standalone processors
get it too), validated as a real Linux username in libreportalValidatePaths.
- Baked everywhere it must be stable: the helpers + CLI wrapper (CHECK_USER now
__MANAGER__, exports LP_MANAGER_USER) via the install-time sed; the systemd unit
exports LP_MANAGER_USER=<manager>. User creation (initUsers), the sudoers
drop-in, and ~35 call sites already used $sudo_user_name, so they follow.
- Fix the stray manager-name literals: install_crowdsec.sh chown, the
check_install_type fallback. (Brand/identity strings like the backup
engine:libreportal tag are left — they're not the username.)
Verified: resolves default/env/flag; wrapper bakes a custom name (admin) with no
placeholders left; validation rejects invalid usernames. The footprint paths
(/etc, /usr/local) stay fixed by design.

Split the single tree into three owner-isolated roots and fix the backup
permission failure (restic, running as the container user, could not write the
manager-owned /docker/backups).
Ownership helper (libreportal-ownership), rewritten for three baked roots:
SYSTEM_DIR (manager) CONTAINERS_DIR + BACKUPS_DIR (container user)
- reconcile now drives each tree to its single owner; backups + the WebUI dir go
to the container user (the actual fix). The container user reaches only the
WebUI bind-mount sources (configs/webui/*) via a scoped _webui_bind_access —
traverse the system root + configs, read configs/webui only, nothing else.
- defence-in-depth: refuse dangerous/relative roots even if mis-baked; new
backups-top action.
Baking: init.sh initRootHelpers now seds __SYSTEM_DIR__/__CONTAINERS_DIR__/
__BACKUPS_DIR__ (alongside __MANAGER__) into every helper at install — the trust
boundary stays root-controlled. svc/socket/appcfg helpers updated to derive from
the baked SYSTEM_DIR; the svc unit now exports LP_*_DIR so the processor resolves
roots authoritatively. A baking-safe '*"__"*' sentinel check survives the sed.
Install/uninstall: initFolders creates the three roots; initContainerLayer hands
containers + backups to the container user; uninstall removes all three
(idempotent on legacy single-tree installs). Remaining functional /docker
literals in init.sh (config reads, setupConfigsFromRepo, uninstall) parameterised.
Compose: the WebUI's two relative ../../configs mounts (the only cross-tree
relative mounts in the tree) are now absolute, filled at generation via a new
CONFIGS_DIR_TAG; CONTAINERS_DIR_TAG likewise for the LP_CONTAINERS_DIR env.
Live box unaffected: installed helpers + the live compose only change on reinstall/
rebuild (both of which fill the tags); the CLI-wrapper heredoc paths are baked in
phase 3.

Bring the remaining deferred subsystems under the scoped sudoers, and drop
the one that's redundant.
Backup engines + app configs -> root-owned helpers (same pattern as
ownership/dns/ssh/socket/svc):
- scripts/system/libreportal-bininstall: install <restic|kopia> — does the
whole pkg-manager/signed-download install itself for a fixed, validated
engine name (no blanket sudo apt-get/install). restic_install/kopia_install
call it.
- scripts/system/libreportal-appcfg: {adguard-auth <user> <bcrypt>|
crowdsec-priority|owncloud-config <public> <host> <ip> <public_ip>} —
faithful ports of the AdGuard yaml / CrowdSec bouncer / ownCloud config.php
rewrites, fixed paths + validated args. adguard_auth/crowdsec_fix_priority/
owncloud_setup_config call it.
- run_privileged: runBinInstall / runAppCfg; init.sh installs + allowlists both.
Retire standalone (host-level) WireGuard — it's a duplicate of the
containerized containers/wireguard app (+ headscale mesh), its slirp4netns
speed rationale is largely moot with a better rootless net backend / typical
WAN-bound throughput, and it was the heaviest host-root subsystem (apt +
sysctl + iptables + /etc/wireguard), the worst fit for the rootless/
least-privilege direction:
- moved scripts/wireguard/ + manage_wireguard.sh + check_wireguard.sh to
scripts/unused/; dropped the install-path call, the Tools menu 'w' entry,
and the requirement check; removed the half-built libreportal-wg helper.
- generate_arrays.sh now also skips system/ (root-owned helpers, never
sourced); arrays regenerated (files_wireguard.sh pruned).

Move the last runtime-critical root file-primitive subsystems behind
root-owned helpers so the type switcher + task service work under a scoped
sudoers:
- scripts/system/libreportal-socket: {rootless|rooted} {on|off} chmod of
the docker sockets (paths computed from config, not caller-supplied;
exit 3 = absent so the *_found flags come from its exit code)
- scripts/system/libreportal-svc: GENERATES + installs the systemd unit
from config (mode/uid/baked manager) — never accepts unit content from
the caller (arbitrary unit = root). Idempotent install/enable/restart.
- ownership helper: add db-own + app-file <app> <relpath> actions
- run_privileged: runSocket / runSvc
- set_socket_permissions -> runSocket; webui_install_systemd -> runSvc
(+ crontab cleanup runs as the manager directly, no sudo -u self)
- before_start: db chown -> runOwnership db-own; traefik cert/yml ->
runOwnership app-file (retires updateFileOwnership/changeRootOwnedFile)
- init.sh installs all five helpers

Two more runtime root file-primitive subsystems moved behind self-
validating root-owned helpers so the scoped sudoers needn't grant blanket
sudo sed/tee/cp on /etc (which is root-equivalent — sudo arg wildcards
match across '/', so even path-scoped entries are bypassable):
- scripts/system/libreportal-dns: {clear|add <ip>} — edits /etc/resolv.conf
only, validates the IP argument
- scripts/system/libreportal-ssh-access: authorized_keys + sshd
PasswordAuthentication management, with the lockout guards moved INTO the
helper (the trust boundary) so a compromised manager can't bypass them
- run_privileged: _runRootHelper dispatcher + runResolv / runSshAccess
(runOwnership now uses it too)
- init.sh: initRootHelpers installs all three helpers root:root 0755 with
the manager name baked in
- setup_dns -> runResolv (+ ping de-sudo'd, works unprivileged); host_access
+ webui_ssh_access -> runSshAccess

Under Model A the runtime runs as the manager, so establishing the
/docker ownership model needs root. Granting the manager a blanket
'sudo chown'/'sudo chmod' in the scoped sudoers would be root-equivalent
(chown /etc/sudoers, ...). Introduce a self-contained, root-owned helper
that performs only a FIXED set of reconciles on FIXED LibrePortal paths,
with owners derived from config + a baked manager name (never the caller)
and a strictly-validated app-name argument.
- scripts/system/libreportal-ownership: the helper (actions: reconcile,
traversal, containers-top, app-perms, webui, taskdir, app-data-nobody)
- run_privileged: runOwnership wrapper (sudo the installed helper; run the
bundled copy directly when already root mid-install)
- init.sh: installOwnershipHelper bakes the manager name and installs it
root:root 0755 to /usr/local/sbin (manager can't modify it)
- libreportal_folders/app_folder/app_update_specifics/task processor:
delegate the ownership chowns to runOwnership instead of runSystem chown
This removes chown/chmod-on-/docker from the runtime sudo surface, a
prerequisite for a non-root-equivalent scoped sudoers.
