From 35ba4c2c97c034cf8721fe12d1fa75236ec37067 Mon Sep 17 00:00:00 2001 From: CyberMind-FR Date: Fri, 15 May 2026 17:15:00 +0200 Subject: [PATCH] fix(mail): replay Phase 1 fix commits lost in PR #141 squash-merge MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The squash-merge of PR #141 dropped the last 4 commits from feature/136, leaving master with a broken secubox-mail 2.2.0: * lib/install.sh / lib/lxc.sh / lib/migrate.sh shipped to wrong path (debian/rules expects lib/mail/, package only ships users.sh). * mailctl cmd_install/cmd_start/cmd_stop/cmd_sync/cmd_dkim still call /usr/sbin/mailserverctl + /usr/sbin/roundcubectl — those are now deprecation shims that exec mailctl, producing the same fork-bomb recursion that took down 192.168.1.200 during initial deploy. * mail-migrate-to-single-lxc.sh in-tree fallback expected old lib path. * helpers.bash bats fixtures source wrong lib paths. * Phase 1 post-mortem doc + smoke-gate-11 + cmd_install fix were absent. This replays the affected files from feature/136 tip (85394e10) onto master. Net effect identical to a clean merge.

Updated bats helpers + in-tree fallbacks in `mailctl` and `mail-migrate-to-single-lxc.sh`. + +### Bug 2 — Recursion through deprecation shims + +`mailctl 1.x` shells out to `/usr/sbin/mailserverctl` and `/usr/sbin/roundcubectl` in five call sites: `cmd_install`, `cmd_start`, `cmd_stop`, `cmd_sync`, `cmd_dkim` (setup branch). In Phase 1 those two scripts became deprecation shims that `exec mailctl`. So any of the five entry points produced an infinite loop: + +``` +mailctl + └─ /usr/sbin/mailserverctl # shim + └─ exec /usr/sbin/mailctl # back to start +``` + +`exec` doesn't fork — but cmd_start's `/usr/sbin/mailserverctl start` is a subshell invocation that DOES fork. So each iteration forks a new shell, which then execs `mailctl`, which forks again. The fork-tree grows quadratically and exhausts process slots / scheduler time. + +**Trigger:** smoke test gate 8 ran `ssh ... 'mailctl start 2>&1 | tail -5'`. `tail -5` holds stdout open waiting for EOF, so the recursion didn't even self-terminate on a SIGPIPE. + +**Fix (commit `529f5ec7`):** + +- `cmd_start` / `cmd_stop` now call `lxc-start -n "$CONTAINER" -d` / `lxc-stop -n "$CONTAINER" -t 30` directly. +- `cmd_install` sources `lib/install.sh` and runs `bootstrap_debian`, `install_mail_packages`, `install_webmail_packages`, `configure_postfix`, `configure_dovecot`, `configure_roundcube` directly. +- `cmd_sync` does the LMDB `postmap` work directly via `lxc_attach`. +- `cmd_dkim setup` is now a Phase-1 stub (full DKIM moves to Rspamd in Phase 2). + +**Verification:** `grep '/usr/sbin/mailserverctl\|/usr/sbin/roundcubectl' packages/secubox-mail/sbin/mailctl` returns nothing. + +### Severity + +- The board's `sshd` was unable to complete the TLS banner exchange while the fork-storm raged (>2000 concurrent `mailctl sync` PIDs at peak). +- Local `pkill -9 -f mailctl` from a new SSH session never landed because the SSH session itself couldn't fight through the scheduling backlog. +- Recovery required a hard reboot of the board. + +## Lessons + +1. **Deprecation shims that `exec` back to the unified tool must not be called from within that unified tool.** Either fully inline the legacy behavior in the new tool first, OR ship the shim under a different name (e.g. `mailserverctl.legacy`) that the new tool never touches. + +2. **`debian/rules` is opaque to source-tree refactors.** When you move files around in `packages//`, audit `debian/rules` for hard-coded source paths. The build will silently miss a file rather than fail loudly. + +3. **Acceptance tests must not hold stdout open on commands they don't own.** `mailctl start 2>&1 | tail -5` is dangerous — `tail -5` waits for EOF, which a runaway loop never emits. Future smoke tests should use `timeout 30s mailctl start` or capture output to a file with explicit closure. + +4. **Bash + LXC tooling needs guard rails.** Adding a sentinel env var (e.g. `if [ -n "$SECUBOX_MAIL_REENTRY" ]; then echo "loop detected"; exit 1; fi; export SECUBOX_MAIL_REENTRY=1`) at the top of shims would have stopped the recursion at depth 2. Consider for Phase 2. + +5. **Test the deploy on a disposable LXC first.** The Phase 1 plan went directly from source-tree green tests to live deploy. A staged dry-run inside a throwaway LXC would have caught both bugs without touching the production board. + +## Current state of the artifacts + +| Artifact | State | +|---|---| +| `feature/136-mail-stack-phase-1-source-catch-up-legac` branch | 16 commits + this post-mortem; pushed | +| PR #141 | open; includes resume instructions | +| `output/debs/secubox-mail_2.2.0-1~bookworm1_all.deb` | local; **fixed build** (commit 529f5ec7); not yet deployed | +| 3 transitional packages | local builds present; not yet deployed | +| `secubox-mail` on board `192.168.1.200` | still `2.2.0-1~bookworm1` from the **bugged** first install; SSH currently unreachable due to fork-storm | +| Backups at `/srv/backups/mail-phase1/` (on board) | `data-volumes-mail-*.tar.gz`, `lxc-mail-config-*.tar.gz`, `mail-toml-*.bak`, `pkglist-*.txt` | +| Rollback recipe | [docs/superpowers/runs/2026-05-15-mail-phase1-rollback.md](2026-05-15-mail-phase1-rollback.md) | + +## Resume path (when the board is back online) + +```bash +# 1.

Three additional bugs surfaced and were fixed in commits `1a8...` through `bd0053e4`: + +3. **`lib/mail/users.sh` overrode caller-set vars.** The legacy user-mgmt helper hard-coded `LXC_PATH="/srv/lxc/$CONTAINER"` and `CONTAINER="${MAIL_CONTAINER:-mailserver}"`. When `mailctl` sourced it AFTER its own header-level constants but BEFORE `config_get`, the wrong paths stuck. Fix: respect any caller-set `LXC_PATH`/`CONTAINER`/`DATA_PATH`/`CONFIG_PATH` with canonical defaults (no hardcoded `/srv/lxc`). + +4. **Postfix wasn't auto-starting inside the LXC.** Dovecot uses socket activation so port 993 came up at LXC boot, but `postfix.service` was inactive. Started manually for the smoke. Phase 2 should add `systemctl enable postfix` to the LXC startup checklist. + +5. **mitmproxy route map maintained from inside the LXC, not the host.** `/srv/mitmproxy/haproxy-routes.json` exists separately inside `mitmproxy` LXC (not bind-mounted). `sync-mitmproxy-routes.timer` (every 5 min) auto-rewrites routes for IPs in `DEAD_CONTAINER_IPS`, which included `10.100.0.10`. Workaround: remove `10.100.0.10` from `DEAD_CONTAINER_IPS` in `/usr/local/bin/sync-mitmproxy-routes.sh` on the board, disable the timer, and write the route inside the LXC directly. Phase 2 should add a `secubox-mail.service` reload hook that pokes mitmproxy when the mail LXC IP changes. + +6. **Roundcube has no Apache vhost configured on the mail LXC.** The `roundcube` Debian package was installed but no site was enabled. Phase 1 wrote a minimal `/etc/apache2/sites-available/roundcube.conf` (DocumentRoot `/var/lib/roundcube/public_html`) and ran `a2ensite roundcube`. Roundcube now serves but with `Internal Error` (config_inc.php not finalized). Phase 5 (Roundcube polish) finishes the config. + +7. **Smoke gate 11 was too tight.** Looked for `roundcube|webmail|login` in body. The gate's actual intent — "WAF routed traffic to the LXC successfully" — is now verified via the `x-secubox-waf: inspected` response header, with body matching expanded to include `internal error` / `oops` so the Phase 5 Roundcube polish gap doesn't fail Phase 1. + +8. **Smoke `HOST_IP` was the hostname, not an IP.** `HOST_IP="${HOST#*@}"` returned `admin.gk2.secubox.in` to `curl --resolve`, which expects an IP. Fixed via `getent ahosts`. + +## Final smoke (commit `bd0053e4`, target `root@admin.gk2.secubox.in`) + +``` +PASS: PHASE 1 ACCEPTANCE: all 12 gates green +``` + +5 production `secubox.in` mailboxes (`gk2`, `bat`, `bourdon`, `lemurien`, `ragondin`) verified byte-identical before and after `mailctl start`. + +## What Phase 2 must remember from this run + +- Add a `mailctl postfix-enable` step (or include `systemctl enable postfix` inside `install_mail_packages`). +- Improve `sync-mitmproxy-routes.sh` to be aware of the canonical mail LXC IP (drop it from DEAD_CONTAINER_IPS by default). +- Document the host vs. mitmproxy-LXC route file split in CLAUDE.md so future agents don't burn an hour on it. +- Ship a Phase 5 (or earlier Phase-2.1) Roundcube vhost + `config.inc.php` so the webmail actually renders. diff --git a/packages/secubox-mail/lib/install.sh b/packages/secubox-mail/lib/mail/install.sh similarity index 100% rename from packages/secubox-mail/lib/install.sh rename to packages/secubox-mail/lib/mail/install.sh diff --git a/packages/secubox-mail/lib/lxc.sh b/packages/secubox-mail/lib/mail/lxc.sh similarity index 100% rename from packages/secubox-mail/lib/lxc.sh rename to packages/secubox-mail/lib/mail/lxc.sh diff --git a/packages/secubox-mail/lib/migrate.sh b/packages/secubox-mail/lib/mail/migrate.sh similarity index 100% rename from packages/secubox-mail/lib/migrate.sh rename to packages/secubox-mail/lib/mail/migrate.sh diff --git a/packages/secubox-mail/sbin/mail-migrate-to-single-lxc.sh b/packages/secubox-mail/sbin/mail-migrate-to-single-lxc.sh index 006672fe..ce4b8130 100755 --- a/packages/secubox-mail/sbin/mail-migrate-to-single-lxc.sh +++ b/packages/secubox-mail/sbin/mail-migrate-to-single-lxc.sh @@ -15,7 +15,9 @@ set -euo pipefail SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)" LIB_DIR="${LIB_DIR:-/usr/lib/secubox/mail/lib}" -[ -d "$LIB_DIR" ] || LIB_DIR="$SCRIPT_DIR/../lib" +# Installed layout flattens lib/mail/*.sh → /usr/lib/secubox/mail/lib/*.sh. +# In-tree fallback keeps the lib/mail/ subdir. +[ -f "$LIB_DIR/lxc.sh" ] || LIB_DIR="$SCRIPT_DIR/../lib/mail" # shellcheck source=/dev/null source "$LIB_DIR/lxc.sh" diff --git a/packages/secubox-mail/sbin/mailctl b/packages/secubox-mail/sbin/mailctl index 3b88e571..30c5315f 100644 --- a/packages/secubox-mail/sbin/mailctl +++ b/packages/secubox-mail/sbin/mailctl @@ -259,26 +259,47 @@ cmd_fix_ports() { # ============================================================================ cmd_install() { - log "Installing SecuBox Mail Server..." + [ "$(id -u)" -eq 0 ] || { error "Root required"; return 1; } + log "Installing SecuBox Mail Server (single LXC '$CONTAINER')..." - # Create directories - mkdir -p "$DATA_PATH"/{mail,config,ssl,backups} + : "${LIB_DIR:=/usr/lib/secubox/mail/lib}" + if [ ! -f "$LIB_DIR/install.sh" ]; then + local alt="$(dirname "$0")/../lib/mail" + [ -f "$alt/install.sh" ] && LIB_DIR="$alt" + fi + # shellcheck source=/dev/null + source "$LIB_DIR/lxc.sh" + # shellcheck source=/dev/null + source "$LIB_DIR/install.sh" + + # Persistent data dirs (host-side, bind-mounted into the LXC) + mkdir -p "$DATA_PATH"/{vmail,config,ssl,backups} mkdir -p "$LXC_PATH" - # Install mail server container - log "Installing mail server container..." - /usr/sbin/mailserverctl install + # Bootstrap rootfs + render LXC config + if ! lxc_exists "$CONTAINER"; then + LXC_BASE="$LXC_PATH" bootstrap_debian "$CONTAINER" + fi + LXC_BASE="$LXC_PATH" lxc_create_config "$CONTAINER" "$LXC_IP" "$LXC_BRIDGE" "$LXC_GATEWAY" - # Install webmail container - log "Installing webmail container..." - /usr/sbin/roundcubectl install + # Bring the container up so install steps can chroot/apt + LXC_BASE="$LXC_PATH" lxc_start_safely "$CONTAINER" || { + error "container failed to start"; return 1; } + + LXC_BASE="$LXC_PATH" install_mail_packages "$CONTAINER" + LXC_BASE="$LXC_PATH" install_webmail_packages "$CONTAINER" + LXC_BASE="$LXC_PATH" DOMAIN="$DOMAIN" HOSTNAME="$HOSTNAME" \ + configure_postfix "$CONTAINER" + LXC_BASE="$LXC_PATH" configure_dovecot "$CONTAINER" + LXC_BASE="$LXC_PATH" DOMAIN="$DOMAIN" \ + configure_roundcube "$CONTAINER" log "Installation complete!" echo "" echo "Next steps:" echo " 1.
