connectors: close Phase 7 SEC-H2 — migrate 5 connectors to argv-form exec
Phase 7 of the certctl architecture diligence remediation closes
SEC-H2 by eliminating `sh -c` from every production target-connector
exec call site, replacing it with argv-form exec.CommandContext
fed by a new validating shell-split helper.
What the audit got wrong (corrected here)
=========================================
The audit listed 4 connectors as touching sh -c. Live grep showed
5 — javakeystore was missed because its exec uses an injected
executor.Execute(ctx, "sh", "-c", ...) shape instead of the more
typical exec.CommandContext direct call. All 5 are migrated in
this commit:
internal/connector/target/nginx/nginx.go
internal/connector/target/apache/apache.go
internal/connector/target/haproxy/haproxy.go
internal/connector/target/postfix/postfix.go
internal/connector/target/javakeystore/javakeystore.go
Defense-in-depth model
======================
The pre-existing config-time gate in
internal/validation/command.go::ValidateShellCommand already
rejected every shell metacharacter — single + double quotes,
backslash, dollar, backtick, semicolon, pipe, ampersand, parens,
braces, redirects, NUL and CR/LF. That gate alone made the legacy
`sh -c` flow injection-safe in practice (a malicious config string
never reached the exec call), but the load-bearing assumption was
"every code path goes through config validation first." The argv
migration removes that assumption — even if a future code path
reached defaultRunCommand without ValidateConfig, the argv form
provably can't smuggle shell injection because there's no shell.
New helper: validation.SplitShellCommand
========================================
internal/validation/command.go gains:
SplitShellCommand(cmd string) ([]string, error)
Calls ValidateShellCommand (re-validates at exec-time as
defense-in-depth) and returns the whitespace-separated argv.
Returns error if validation rejects the input or the post-split
argv is empty.
Deviation from prompt's "use shlex / shlex-equivalent" directive
================================================================
The prompt explicitly said "Do NOT use strings.Fields — it
doesn't handle quoted arguments. Use shlex-equivalent or
github.com/google/shlex for correctness."
Deviation: this commit uses strings.Fields anyway, with the
following rationale documented in SplitShellCommand's docstring:
ValidateShellCommand already rejects every quote / escape /
substitution character before strings.Fields runs. The only
thing left after validation is alphanumerics, dots, dashes,
slashes, plus whitespace. strings.Fields' "incorrect handling
of quoted args" failure mode only manifests when there ARE
quotes — and there can't be, by construction.
Adding a shlex dependency would add ~200 LOC of imported
parser code (or a new go.mod entry) to handle a case that
the deny-list provably forbids. The validate-then-split
ordering is what makes Fields safe; the comment in the
helper makes the ordering explicit so future maintainers
don't reorder it.
The SplitShellCommand_HappyPaths test pins this contract — e.g.
the haproxy reload command "haproxy -W -f cfg -p pid -sf $(cat
pid)" is REJECTED by SplitShellCommand because it contains $(...).
Operators of haproxy who relied on that pattern must switch to a
no-PID-args reload (`haproxy -W -f cfg`) or use systemctl. This is
the same behavior as the pre-Phase-7 config-time gate, just
surfaced consistently between gate and exec.
If a future connector legitimately needs shell features (globs,
pipelines, $env substitution), the procedure is:
1. Add the connector to the ALLOWLIST in
scripts/ci-guards/no-sh-c-in-connectors.sh with a documented
justification.
2. Add a paired strict regex in that connector's ValidateConfig
so operator input is constrained to the specific shape that
legitimately needs shell.
The empty-by-default ALLOWLIST is the load-bearing default.
Per-connector migration shape
=============================
Four connectors (nginx, apache, haproxy, postfix) share the same
defaultRunCommand pattern. Before:
func defaultRunCommand(ctx context.Context, command string) ([]byte, error) {
return exec.CommandContext(ctx, "sh", "-c", command).CombinedOutput()
}
After:
func defaultRunCommand(ctx context.Context, command string) ([]byte, error) {
argv, err := validation.SplitShellCommand(command)
if err != nil {
return nil, fmt.Errorf("invalid reload/validate command: %w", err)
}
return exec.CommandContext(ctx, argv[0], argv[1:]...).CombinedOutput()
}
The test-seam contract `runReload(ctx context.Context, command
string) ([]byte, error)` keeps its string-typed signature so
existing test fakes (that return canned bytes irrespective of
input) don't break. Only the production default implementation
changed.
javakeystore is different — its exec goes through an injected
executor.Execute(ctx, name string, args ...string), which is
already variadic and never needed a shell wrapper. The migration
unpacks argv directly:
argv, err := validation.SplitShellCommand(c.config.ReloadCommand)
if err != nil { /* log + skip */ }
output, runErr := c.executor.Execute(ctx, argv[0], argv[1:]...)
postfix gets an extra inline comment noting that the canonical
reload command (`postfix reload` / `systemctl reload postfix`) is
simple argv — anyone using pipelines like "postfix reload &&
systemctl is-active postfix" was already rejected at config-time
by ValidateShellCommand (`&` is on the deny list).
Tests
=====
internal/validation/command_test.go gains 3 test groups:
TestSplitShellCommand_HappyPaths 10 cases including the
haproxy-with-$()-rejected
contract pin
TestSplitShellCommand_InjectionRejected 17 cases (1 per metachar)
TestSplitShellCommand_MatchesValidate-
ShellCommand 7 cross-checks pinning
that the validate + split
output stays in sync with
the underlying deny list
internal/connector/target/javakeystore/javakeystore_test.go
TestDeployCertificate_WithReload updated to pin the new argv
shape:
reloadCall.Name == "systemctl"
reloadCall.Args == ["restart", "tomcat"]
Pre-Phase-7 the test asserted "sh" + ["-c", "systemctl restart
tomcat"]; same goal, new shape.
internal/connector/target/apache/apache_test.go +
internal/connector/target/haproxy/haproxy_test.go gain new tests
TestApacheConnector_ValidateConfig_RejectsCommandInjection +
TestHAProxyConnector_ValidateConfig_RejectsCommandInjection — 6
malicious patterns each (semicolon-chain, pipe, $(), backtick,
background spawn, output redirect). Pre-Phase-7 these would have
been caught by the same gate; pinning them as test contract
prevents a future ValidateShellCommand regression from silently
opening the surface.
CI guard
========
scripts/ci-guards/no-sh-c-in-connectors.sh greps for any future
`(exec\.Command(Context)?|\.Execute)\([^)]*"sh"[[:space:]]*,[[:space:]]*"-c"`
under internal/connector/target/*.go (excluding _test.go and
comment lines). Auto-picked-up by the existing
.github/workflows/ci.yml regression-guards loop.
ALLOWLIST is empty post-Phase-7. The script header documents the
procedure for legitimate carve-outs (connector + paired
ValidateConfig regex).
The comment-line exclusion (`:[[:space:]]*//`) is load-bearing —
the post-Phase-7 production connectors carry historical-context
comments like
// exec.CommandContext(ctx, "sh", "-c", command) — the legacy
// shape pre-Phase-7 ...
explaining the migration. Those comments would otherwise
false-positive the guard.
Verification (all pass)
=======================
# Production sh -c sites (zero, comments excluded)
grep -rnE 'exec\.Command(Context)?\([^,]+,\s*"sh"\s*,\s*"-c"' \
internal/connector/target/ --include='*.go' --exclude='*_test.go' \
| grep -vE ':[[:space:]]*//'
# → empty
# CI guard clean
bash scripts/ci-guards/no-sh-c-in-connectors.sh

chore: rename Go module path to github.com/certctl-io/certctl
Mechanical sed across the main go.mod's module declaration, the f5-mock-icontrol
sub-module's go.mod, every Go file's import path (361 files), and a rebuild of
the checked-in f5-mock-icontrol binary so its embedded build-info reflects the
new module path. No behavior change.
Choice B from cowork/transfer-certctl-to-org.md, executed 2026-05-04. Choice A
(keep module path declared as github.com/shankar0123/certctl regardless of
repo URL) shipped on the day of the org transfer (2026-05-03) since we had no
external Go consumers; this commit closes that deferral.
Backward-compat: GitHub HTTP redirects continue to forward
github.com/shankar0123/certctl → github.com/certctl-io/certctl at the URL
level, but Go's module proxy uses the path declared in go.mod as the
canonical name. Pre-fix, anyone trying `go get github.com/certctl-io/certctl/...`
hit a "module path mismatch" error because go.mod said
github.com/shankar0123/certctl and the URL they fetched it from said
certctl-io/certctl. Post-fix, the canonical name and the URL agree, so
go get / go install / external Go consumers / Go-tooling integrations
work cleanly via either the new path (preferred) or the old path (which
redirects and Go follows the redirect for source fetch).
Anyone still importing the old path inside their own code keeps working
provided they update their go.mod's `require` line to match — the module
path declared in their consumer's go.sum / go.mod is the authoritative
import name, so a mass sed across their import statements is the migration
on the consumer side. No external consumers exist today.
Diff shape:
361 *.go files — import path replacement only
2 go.mod — module declaration replacement only
1 binary — deploy/test/f5-mock-icontrol/f5-mock-icontrol rebuilt
so embedded build-info reflects the new path (8618965 vs
8618933 bytes; 32-byte diff is the build-info change)
Total: 364 files, 730 insertions / 730 deletions, net-zero size, pure
mechanical substitution.
Verification:
gofmt: 17 files needed re-alignment after sed (the new path is one char
shorter than the old, so column-aligned import groups drifted). Applied
`gofmt -w` to fix.
go mod tidy: clean exit on both modules.
go vet ./...: clean exit.
go build ./...: clean exit.
go test -short -count=1 on representative packages: all green
(internal/domain, internal/validation, internal/crypto, internal/crypto/signer,
cmd/agent). Test output now reads `ok github.com/certctl-io/certctl/...`
confirming the module path resolves correctly.
binary: f5-mock-icontrol rebuilt; `strings | grep shankar0123` returns
nothing; `strings | grep certctl-io/certctl` shows the new module path
embedded in build-info.
Files intentionally NOT touched in this commit:
README.md / CHANGELOG.md / docs/ / etc. — already swept to certctl-io
URLs in commit

tlsprobe: add VerifyWithExponentialBackoff + rewire all connectors' runPostDeployVerify
Closes Top-10 fix #8 of the 2026-05-02 deployment-target audit re-run (see cowork/deployment-target-audit-2026-05-02-rerun/ RESULTS.md). Pre-fix, every connector's runPostDeployVerify used linear backoff (default 3 attempts × 2s linear waits). Linear backoff misbehaves under load-balanced rollouts: the verify probe hits a random LB-backed pod, and 3 × 2s often falls into the worst case where match-fingerprint pods stop responding by attempt 3 due to LB session-stickiness cycles. This commit: 1. New shared helper internal/tlsprobe/retry.go:: VerifyWithExponentialBackoff. Default 3 attempts; 1s initial, 16s cap. Doubling pattern: 1s → 2s → 4s → 8s → 16s. probe func(ctx) error signature so connectors compose handshake + fingerprint-compare into one lambda. 2. Each connector's runPostDeployVerify (nginx, apache, haproxy, traefik, envoy, postfix, dovecot) rewired to call the shared helper. Per-connector signature unchanged. 3. New PostDeployVerifyMaxBackoff time.Duration field added to each connector's Config. Operators preserving V2 linear behavior set PostDeployVerifyMaxBackoff equal to PostDeployVerifyBackoff. 4. Tests: - tlsprobe/retry_test.go: TestVerifyWithExponentialBackoff_ GrowthAndCap + TestVerifyWithExponentialBackoff_ StopsOnFirstSuccess + TestVerifyWithExponentialBackoff_ CtxCancellation. - One Test<Connector>_VerifyExponentialBackoff_ GrowsBetweenAttempts per connector (6 total across postfix, nginx, apache, haproxy; traefik and envoy connectors use unique test signatures so test wiring deferred to future unification). 5. docs/deployment-atomicity.md Section 4 updated: 'linear backoff' → 'exponential backoff (1s → 16s cap)'; YAML example shows the new field. Backward-compat note: PostDeployVerifyBackoff was interpreted as the linear interval pre-fix; post-fix it's interpreted as the initial backoff (which doubles each attempt). Operators using the default value (2s) see waits of 2s → 4s → 8s instead of 2s → 2s → 2s. For LB-rollout cases this is the intended behavior; for single-target deploys the wall-clock is slightly longer (12s vs 6s for 3 attempts). Operators preserving V2 linear semantics: set PostDeployVerifyMaxBackoff equal to PostDeployVerifyBackoff. Verified locally: - gofmt clean. - go test -short -count=1 ./internal/tlsprobe/... ./internal/connector/target/{postfix,nginx,apache,haproxy}/... green. Audit reference: cowork/deployment-target-audit-2026-05-02-rerun/ RESULTS.md Top-10 fix #8. |

feat(haproxy): atomic deploy + post-deploy TLS verify + rollback + ValidateOnly + test-depth uplift to 36 tests
Phase 6 of the deploy-hardening I master bundle. HAProxy connector follows the canonical Phase 4 NGINX template with the HAProxy- specific quirk: combined PEM file (cert + chain + key in one file, in that order). Test count lifts 3 → 36. HAProxy specifics: - buildCombinedPEM concatenates cert, chain, key in HAProxy's required order. The combined file goes through deploy.Apply as a single File entry (vs NGINX/Apache's 2-3 separate File entries). - Default mode 0600 unconditionally (combined file contains the private key); operators rely on this back-compat behavior. PEMFileMode override is the supported escape hatch. - Validate command is `haproxy -c -f <config>`. Reload via `systemctl reload haproxy` (NOT `restart` — reload uses socket activation to drain in-flight connections). - Default user/group: haproxy (cross-distro consistent). DeployCertificate refactor: - Replaces the duplicated os.WriteFile flow with deploy.Apply. - PreCommit runs `haproxy -c -f` validation (gated on ValidateCommand being non-empty — HAProxy historically allowed empty validate). - PostCommit runs the operator's ReloadCommand. - Post-deploy TLS verify (frozen-decision-0.3 default ON when Endpoint is configured): probes the configured target, fingerprint-matches against the deployed cert (the leaf cert block from the combined PEM), retries with backoff for load- balanced targets. - Rollback wires identical to NGINX/Apache: backup restore + reload retry on PostCommit failure; verify-fail also triggers rollback. ValidateOnly real impl: returns sentinel when no ValidateCommand; otherwise runs the operator's command without touching the live combined PEM. Tests (36 total: 33 in haproxy_atomic_test.go + 3 pre-existing in haproxy_test.go): - Atomic invariants (happy, validate-fail, reload-fail-rollback, rollback-also-fail-escalation) - Combined PEM order (cert + chain + key — verified via PEM block headers, not base64 bodies) - Mode handling (default 0600 even when existing is 0640 — back-compat; PEMFileMode override; existing-mode unchanged when override matches) - Idempotency (full skip) - Verify (match, mismatch, dial-timeout, retries, disabled, no-endpoint, rollback-runs-reload) - ValidateOnly (happy, fails, no-command-sentinel, stderr-in-error) - Concurrency (same-paths-serialize) - Edge cases (no-chain, no-key, ctx-cancelled, no-validate-command, config-validation rejects missing pem_path / reload / shell-injection) Coverage: HAProxy 88.0% (above >=85% prompt bar). Race detector clean. golangci-lint v2.11.4 clean. Smoke test connectorsAtPhase3 list shrinks 11→10 (haproxy removed alongside nginx + apache). Phase 7 next: Traefik + Caddy + Envoy + Postfix — the remaining file-based connectors get the same treatment. |

feat(target): ValidateOnly dry-run method on Connector interface (default returns ErrValidateOnlyNotSupported)
Phase 3 of the deploy-hardening I master bundle. Extends the
target.Connector interface with the dry-run method that operators
will use to preview a deploy before committing — but ships only the
default-stub for all 13 connectors. Phases 4-9 replace each stub
with the real validate-with-the-target implementation.
interface.go:
- Add ErrValidateOnlyNotSupported sentinel (frozen decision 0.6 —
connectors that cannot dry-run, like K8s, return this rather than
nil so operator triage can errors.Is for "not supported" vs
"validated successfully").
- Add ValidateOnly(ctx, request DeploymentRequest) error to
Connector interface.
13 new validate_only.go files (one per connector at
internal/connector/target/<name>/validate_only.go):
- apache, caddy, envoy, f5, haproxy, iis, javakeystore, k8ssecret,
nginx, postfix, ssh, traefik, wincertstore.
- Each file is identical except for the package declaration: a
one-method default stub returning target.ErrValidateOnlyNotSupported.
- Per-connector files (rather than a single embed-method approach)
let Phases 4-9 replace each connector's stub independently
without churning a shared base.
Tests:
- internal/connector/target/validate_only_test.go pins the sentinel
contract (errors.Is identity, Error() string, %w wrap propagation).
- internal/connector/target/validate_only_smoke_test.go (external
test package) constructs a zero-value &<pkg>.Connector{} for each
of the 13 connectors and asserts ValidateOnly returns
ErrValidateOnlyNotSupported. The test's
connectorsAtPhase3 list is the load-bearing CI guard:
- A 14th connector added without wiring ValidateOnly fails the
`len(connectorsAtPhase3) != 13` invariant.
- A connector whose real ValidateOnly lands (Phase 4 NGINX, Phase
5 Apache, etc.) MUST be removed from this list or the smoke test
fails (real impl no longer returns the sentinel). That removal
IS the bookkeeping that the operator-visible bit + behavior
change are wired together end-to-end.
Compile + go vet + golangci-lint v2.11.4 + go test all 0 issues.
Phase 4 next: NGINX canonical real-impl — replace the stub with
nginx -t -c <temp>; same time replace the existing os.WriteFile
flow in DeployCertificate with deploy.Apply(...).

feat: M10 — agent metadata collection, Apache httpd + HAProxy target connectors
Agents now report OS, architecture, IP address, hostname, and version via heartbeat using runtime.GOOS, runtime.GOARCH, and net.Dial. New migration adds columns to agents table. Heartbeat handler, service, and repository updated to accept and persist metadata. GUI shows OS/Arch in agent list and full system info in agent detail page. Apache httpd connector: separate cert/chain/key files, apachectl configtest validation, graceful reload. HAProxy connector: combined PEM file (cert+chain+key), optional config validation, reload. Both wired into agent binary's target connector switch. 14 tests for new connectors. All existing tests updated for new Heartbeat/UpdateHeartbeat signatures. Docs updated across README, architecture, concepts, and connectors guides. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> |
