glm-5.1 54f1725173 Decompose security review #003 findings into 17 fix tasks and 1 review task
Address 4 critical, 8 warning, and 5 suggestion findings from the
security and bug review by creating atomic, dependency-ordered tasks:

Critical fixes (C1-C4): rate limiter IP source (ADR-025), InFlightCounter
increment + drain interval, connector timeout ceiling (ADR-026), JSON format
without log file.

Validation tightening (W1, W2): upstream host validation, ACME contact email
validation.

Robustness (W3, W4, W5, W12): upstream URI error handling (502 not silent
drop), admin socket resource limits (ADR-027), TlsMode wildcard mismatch,
http_port u32→u16.

Code quality (W6, W10, W11, S1, S3, W8/W9): config type consolidation,
TokenBucket field visibility, reload_mutex #[cfg(test)], dead code removal,
root cert count logging, misleading test names.

Test coverage (S10): rate limiter ConnectInfo tests (depends on C1 fix).

Review: post-security-fix-review checkpoint covering all critical fixes
and sensitive config consolidation path.

fix/log-root-cert-count Log system root certificate count at startup (S3) pending
single trivial isolated implementation
S3

Description

root_certs() loads native certificates silently — only logs errors. If the system has zero root certificates (misconfigured CA bundle), all HTTPS upstream connections will fail with opaque TLS errors and no diagnostic message.

Changes Required

src/proxy/handler.rsroot_certs() function (lines 246-258):

  • Add an info-level log with cert count and warn if zero:
    fn root_certs() -> rustls::RootCertStore {
        let mut roots = rustls::RootCertStore::empty();
        let result = rustls_native_certs::load_native_certs();
        for cert in result.certs {
            roots.add(cert).ok();
        }
        let cert_count = roots.len();
        let error_count = result.errors.len();
        if cert_count == 0 {
            warn!(certs_loaded = cert_count, errors = error_count,
                "no system root certificates loaded — HTTPS upstream connections will fail");
        } else {
            info!(certs_loaded = cert_count, errors = error_count,
                "loaded system root certificates");
        }
        for err in &result.errors {
            warn!(error = %err, "failed to load native certificate");
        }
        roots
    }
    

Acceptance Criteria

  • Info-level log with cert count when certs > 0
  • Warn-level log when cert count is 0
  • Error count included in log output
  • Individual cert load errors still logged at warn level
  • cargo test passes
  • cargo clippy passes with no warnings
