From 7d71108e527223076ab8ae8b5f711adb189c2a0b Mon Sep 17 00:00:00 2001 From: codehippie1 Date: Fri, 29 May 2026 14:33:49 -0400 Subject: [PATCH 01/23] v0.9.3: Rust 2024 edition, optional build features, SQLite + security hardening - Migrate to the Rust 2024 edition; declare an MSRV; move lint policy into Cargo.toml. - Add optional build features (audit/mcp/observe/logscrape/waste), all default-on; `cargo build --no-default-features` now produces a lean core-proxy build. - Make path/command security rules case- and separator-insensitive so `~/.SSH` and mixed-separator Windows paths cannot bypass a `~/.ssh` deny rule. - Forward --upstream-google and --rewrite-anthropic-cache through `start --daemon`. - Add opt-in cost-spiral enforcement via [loop_detection].cost_spiral_enforce (off by default). - Harden SQLite (WAL + busy_timeout, poisoned-lock recovery, response-path writes off the async runtime). - Deduplicate repository.rs row-mappers. --- CHANGELOG.md | 26 ++++++ CLAUDE.md | 8 ++ Cargo.lock | 2 +- Cargo.toml | 26 +++++- editor/vscode/package.json | 2 +- packaging/mcp/server.json | 2 +- src/budget/loop_detector.rs | 68 ++++++++++++++++ src/cli/daemon.rs | 5 ++ src/cli/mod.rs | 27 +++++++ src/cli/start.rs | 6 +- src/cli/status.rs | 123 +++++++++++++++++++---------- src/config/types.rs | 8 ++ src/lib.rs | 7 +- src/logscrape/aider.rs | 2 +- src/proxy/forwarding.rs | 12 ++- src/proxy/handler.rs | 21 ++++- src/proxy/mod.rs | 2 + src/proxy/streaming.rs | 4 +- src/security/rules.rs | 99 ++++++++++++++++++----- src/storage/mod.rs | 21 ++++- src/storage/repository.rs | 104 +++++++++--------------- src/waste/rules.rs | 12 +-- src/waste/types.rs | 2 +- tests/integration/budget_test.rs | 1 + tests/integration/daemon_test.rs | 6 +- tests/integration/init_test.rs | 6 +- tests/integration/pipeline_test.rs | 2 + tests/unit/logscrape_test.rs | 6 +- 28 files changed, 455 insertions(+), 155 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index b60c34b..73cfc5c 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -2,6 +2,32 @@ All notable changes to Burnwall. +## [0.9.3] — 2026-05-29 + +### Fixed + +- **Path/command security rules are now case- and separator-insensitive**, so an + access to `~/.SSH/id_rsa` — or a mixed `\`/`/` Windows path — can no longer slip + past a `~/.ssh` deny rule on case-insensitive filesystems (Windows, default macOS). +- **`start --daemon`** now forwards the `--upstream-google` and + `--rewrite-anthropic-cache` flags to the background process instead of dropping them. + +### Added + +- **Opt-in cost-spiral enforcement** — set `[loop_detection].cost_spiral_enforce = true` + to block the next request once rolling spend exceeds `max_cost_per_window`.

Now: - `stop` pauses routing: active env files become a paused stub (distinct from disable-routing's explicit stub), with a warning that already- open terminals keep the vars plus the exact unset command - one that does NOT flip the persistent state, unlike `disable-routing --eval`. Runs even when no proxy was found (a crashed daemon strands routing too). Opt out with --keep-routing. - `start` resumes routing once the port is bound: paused/missing env files are re-enabled, active ones refreshed with the current proxy URL (picks up a port change), and an explicit disable-routing is respected and reported. Never wires up a never-configured shell. Opt out with --no-routing. A foreground start pauses routing again on its way out (Ctrl-C), mirroring stop. - `start --daemon`: the launcher resumes routing after the child reports ready (the detached child gets --no-routing, its output goes nowhere). - `upgrade` keeps routing across its transient stop/restart, but pauses it on every path that ends with the proxy still down (--no-restart or a failed restart). `sidecar` never touches local shell routing; `uninstall` skips the pause since it tears routing down fully anyway. - `status`'s not-routed hint now points at `burnwall start` when routing is merely paused, instead of enable-routing. --- CHANGELOG.md | 25 +++++ src/cli/daemon.rs | 26 +++++- src/cli/routing.rs | 211 ++++++++++++++++++++++++++++++++++++++++++- src/cli/sidecar.rs | 3 + src/cli/start.rs | 69 ++++++++++++++ src/cli/status.rs | 26 +++++- src/cli/stop.rs | 96 ++++++++++++++++---- src/cli/uninstall.rs | 6 +- src/cli/upgrade.rs | 17 +++- 9 files changed, 442 insertions(+), 37 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index b4a8192..d91cd1b 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -2,6 +2,31 @@ All notable changes to Burnwall. +## [Unreleased] + +### Fixed + +- **Talking *about* a denied path or command no longer blocks the request.** + The proxy's security scan previously applied every rule to every string in + the request body, so a system prompt, chat message, tool definition, or tool + result that merely *mentioned* `~/.ssh` or `rm -rf` returned a 403 — e.g. a + project's CLAUDE.md documenting a deny list made every Claude Code request + from that repo fail (surfacing in the client as a bogus "run /login" auth + error).
