install: resolve dependencies from every enabled repository

[andrebrait]

Refs pfBlockerNG/pfBlockerNG#3484. Source-repository counterpart: pfBlockerNG/pfBlockerNG#3486.

Problem

The published install.sh installed pfBlockerNG with pkg install -r <pfblockerng-channel> (step 9d) and pkg install -f -r <pfblockerng-channel> <pkg>-<version> (step 9c). -r confines dependency resolution to our repository, and pfBlockerNG's dependencies are only in Netgate's pfSense repository, so a fresh firewall fails with exit 5 (lighttpd, the first of 12, reported missing).

Change

• Steps 9c and 9d drop -r. Repository priority 100 selects our build; the existing step-10 check (pkg query %R must equal the channel repository, else exit 6) still proves where pfBlockerNG came from.
• The failure messages and their "finish with:" command no longer carry -r; comments reconciled.
• docs/install.sh is regenerated by the render-site workflow on merge.

Tests

tests/test_channel_install.py: the fake pkg models priority, per-repository offers, dependencies, and -r confinement. New cases cover a fresh install with a dependency only another repository offers (four channels), legacy identity replacement, reinstall with a new foreign-only dependency, a repository outranking ours (exit 6), and both failure messages.

• RED on the unmodified script: 21 failed, 75 passed (test file blob a6c77e1).
• GREEN after the fix, same blob: 96 passed; full suite 800 passed.

The live pfSense VM reproduction (red on devel, green on the fix) runs in pfBlockerNG/pfBlockerNG#3486.

Summary by CodeRabbit

• Bug Fixes
  • Fresh installs, reinstalls, upgrades, and migrations can resolve packages and required dependencies from any enabled repository.
  • Package selection follows repository priority. If a higher-priority repository supplies the main package from an unexpected source, the install check reports the mismatch.

📝 Walkthrough

Walkthrough

Fresh installs and forced reinstalls no longer restrict package resolution to the channel repository. Tests model repository priorities and dependencies, including cases where a dependency comes from another repository and where repository verification fails.

Changes

Repository-aware package installation

Layer / File(s)	Summary
Model package offers and dependency resolution tests/test_channel_install.py	The fake pkg command models offers, priorities, version selection, and dependency-plan resolution. Helpers seed repository data and inspect installed packages.
Use unqualified install commands scripts/install.sh, tests/test_channel_install.py	Fresh installs and forced reinstalls omit -r. Existing install expectations and recovery-command checks reflect the unqualified commands.
Verify cross-repository dependencies tests/test_channel_install.py	Tests cover dependency resolution across fresh installs and migration paths. They also check that a higher-priority foreign repository causes repository verification to fail.

Priority: ⬆️ High

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to bc561

The installer checks the installed package’s repository, but selection tests do not match pkg when a foreign package is newer. Correct the test model before relying on this coverage.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to bc561

Resolving dependencies from other repositories addresses the installation failure, but also permits another enabled repository to supply the main package. Verification detects the wrong source only after installation, when package files and scripts may already have changed the firewall. Exposure requires a selectable package from an enabled repository; this is not an unauthenticated remote entrypoint.

Retained concerns

• Medium · security · inferred: Removing repository confinement allows a selectable foreign canonical package to change the firewall before its repository is rejected. Exit 6 prevents a successful completion report, but is not a pre-execution trust control or rollback. Compared with the base, the main package is no longer constrained to the selected channel during installation.

Security review details

Security Blast Radius

• inferred — The independently exposed asset is each firewall executing the installer. A selected package runs through the privileged package lifecycle, potentially affecting host files, services and configuration. Broader fleet exposure depends on which firewalls enable and select the same repository; that deployment scope is not established.

Security Findings and Attack Paths

• inferred — An attacker would need control of a package offer accepted under an already enabled repository's trust policy and selected by pkg. The resulting path is foreign canonical offer, privileged installation and lifecycle execution, then repository-mismatch detection. This is a conditional architecture concern, not a reproduced malicious-package exploit.

Trust Boundaries and Controls

• observed — The strongest retained control is explicit post-install identity verification: a foreign repository or unexpected version cannot receive the installer's success report. Package-script failures are also detected. Both controls operate after pkg has executed, so they are detective rather than preventive for package side effects.

Resilience and Maintainability Implications

• inferred — Retry can repair package metadata convergence, but cannot be assumed to undo effects from a previously executed foreign package. The unchanged cleanup and verification logic therefore does not contain all consequences of the newly widened selection boundary.

Hardening Proposals

• proposed — Bind the canonical package to an authenticated selected-channel artifact before privileged mutation while retaining cross-repository dependency resolution. Validate the chosen mechanism against supported pkg versions rather than relying solely on the priority-first test model.

Through ranked repositories, none would stop.
A fresh install chose its way,
A reinstall joined the fray.
Dependencies found a home,
Then all the tests came back to roam.}

Adversarial review — condensed round 1 (contract, correctness/hostile input, test honesty, over-engineering)

• Heads reviewed: install: resolve dependencies from every enabled repository pfBlockerNG#3486 290fa70f6ca3001708f2a61a098bfe9f015b8ca3; install: resolve dependencies from every enabled repository #40 a331a7bc27b5f4a886021313b3ac51dcbfb8d773.
• Invocation: OMP reviewer agent (single condensed round), reasoning lever high.
• Verdict: no production defect in either PR. Red/green re-executed in scratch copies (source 21 failed → 108 passed; pkg 21 failed → 96 passed). Mutations: -r reintroduced in 9d (12 killed), in 9c (7–8 killed), step-10 repo check removed (killed by 1 test), -r in either failure message (killed), -f dropped (killed by argv pins).

#	Severity	Finding	Planned outcome
1	blocking	#3486 body lacks the Frozen RED test table, so Coverage pairing fails	apply (PR body)
2	nitpick	Without -r, pkg install refreshes every enabled catalogue and may upgrade out-of-date dependencies; not documented	apply (comment + architecture note)
3	nitpick	Live proof covers only the 9d path; the 9c/legacy/channel-move/nightly-downgrade repo legs were not run on the head	apply (full repo marker run on the fixed head)
4	nitpick	Hermetic foreign offer (3.2.14) is below ours, so "priority beats version" is a stub tie-break artefact	apply (foreign offer 9.9.9, red/green re-run)
5	nitpick	Nightly-policy phrase "repository-qualified downgrade" is now loose	skip: release-policy wording pinned by tests/test_release_skill_contract*.py, not a description of install.sh flags
6	nitpick	Step 10 is detective: a higher-priority foreign repo could install its build before exit 6	skip: accepted by the owner decision on #3484; pinned by the new R4 test
7	nitpick	Live test emulates a fresh box by removing one leaf dependency, not all 12	skip in code; real Fresh v2 lab confirmation requested from the owner
8	nitpick	Two test names still say "qualified"; R2 overlaps R1	skip: renaming churns frozen hashes; R2 is a brief coverage row

7. One-dependency fresh-box emulation — skipped in code; Fresh v2 lab confirmation requested from the owner after merge.
8. "qualified" test names / R2 overlap — skipped: renames churn frozen hashes; R2 is a brief coverage row.
