On connection, both sides authenticate using +their Ed25519 private keys. A MITM attacker without the private key cannot +authenticate. + +**Residual risk**: If the peer code is exchanged over an untrusted channel +(e.g., posted publicly), an attacker who controls a hostname could substitute +their public key. **Users should only share peer codes with trusted peers.** + +**Unproven**: Formal verification of the handshake protocol +(`src/session_hs/`) has not been performed. + +--- + +### T-3: Replay attacks + +**Threat**: An attacker captures and replays encrypted packets. + +**Mitigation**: Each packet includes a monotonically increasing nonce. +Packets with a nonce lower than the last accepted nonce are rejected. +libsodium's `crypto_box_open_easy` / `crypto_secretbox_open_easy` includes +an authentication tag that prevents tag forgery. + +**Residual risk**: Nonce state is not persisted across restarts; replay +across sessions is not prevented (same key pair, new session starts at nonce 0). +This is acceptable for the current LAN use case. + +--- + +### T-4: Private key theft + +**Threat**: An attacker gains read access to `~/.config/rootstream/identity.key`. + +**Mitigation**: The key file is written with `chmod 600` on creation. +File permissions prevent unprivileged processes from reading it. + +**Residual risk**: Root-level access on the host machine bypasses file +permissions. This is outside the threat model scope (physical access / +privilege escalation). + +**Recommendation**: Back up the key file and rotate it if you suspect +compromise (delete the key file; a new keypair will be generated on next +run). + +--- + +### T-5: Denial of service (DoS) + +**Threat**: An attacker floods the host UDP port to disrupt streaming. + +**Mitigation**: Packets failing authentication are dropped before +processing. The host does not allocate expensive resources before +authentication. + +**Residual risk**: High-rate UDP flood can saturate network bandwidth +or cause packet loss. RootStream does not implement rate limiting at the +network layer. Firewalling the streaming port to known peer IPs is +recommended on public networks. + +--- + +### T-6: uinput privilege escalation (host side) + +**Threat**: The host process uses `/dev/uinput` to inject input events. +If compromised, it could inject arbitrary input to the host machine. + +**Mitigation**: uinput access is limited to users in the `input` group. +The RootStream host only injects events received from authenticated peers. + +**Residual risk**: If a peer is compromised, they can inject arbitrary +input to the host display. Only connect to peers you trust. + +--- + +### T-7: Recording file exposure + +**Threat**: The `--record` flag saves stream content to disk. + +**Mitigation**: Recording is opt-in and explicit. The file path is +user-specified. Files are not encrypted at rest. + +**Recommendation**: Store recordings in an encrypted volume if stream +content is sensitive. + +--- + +## Security Controls Summary + +| Control | Implemented |

RootStream Architecture Boundary Rules + +This document defines the target architectural layering for RootStream, +the rules for crossing subsystem boundaries, and the isolation policy for +non-core surfaces. + +It is a companion to [`docs/ARCHITECTURE.md`](../ARCHITECTURE.md) (which +describes subsystem components) and +[`docs/SUPPORT_MATRIX.md`](../SUPPORT_MATRIX.md) (which defines surface +maturity). + +--- + +## Architectural Layers + +RootStream is organized into three layers: + +``` +┌─────────────────────────────────────────────────────┐ +│ PRESENTATION LAYER │ +│ GTK tray · KDE client · Web dashboard · CLI │ +│ Android app · iOS app │ +└──────────────────┬──────────────────────────────────┘ + │ rs_client_session API / vtable callbacks

discovery.* │ +└─────────────────────────────────────────────────────┘ +``` + +--- + +## Boundary Rules + +### Rule B-1: Presentation → Session + +- **Allowed**: The presentation layer may call into the session layer + **only through the public API** defined in + `include/rootstream_client_session.h` (`rs_client_session_*` functions). +- **Prohibited**: Presentation code must **not** directly call backend + functions (e.g., `audio_playback_write_alsa`, `capture_drm_frame`). +- **Rationale**: The KDE client, Android app, and web backend all share + the same session layer without needing to know which audio or capture + backend is active. + +### Rule B-2: Session → Backend + +- **Allowed**: Session code uses **vtable pointers** stored in + `rootstream_ctx_t` (`capture_backend`, `encoder_backend`, + `audio_capture_backend`, `audio_playback_backend`) to dispatch to + the selected backend. +- **Allowed**: Session code may call typed vtable functions like + `ctx->capture_backend->capture_fn(ctx, &frame)`. +- **Prohibited**: Session code must **not** call backend functions + directly by name (i.e., no `capture_drm_frame(ctx, &frame)` in + `service.c`). +- **Rationale**: Vtable dispatch enables fallback selection and testing + with stub backends. + +### Rule B-3: Backend isolation + +- **Each backend file** (`drm_capture.c`, `audio_playback_alsa.c`, etc.) + owns its own internal state via `void *` pointers inside + `rootstream_ctx_t`. +- **Backend files must not** directly include or call into sibling + backend files. +- **Backend files may** include `include/rootstream.h` for the shared + context type. + +### Rule B-4: Platform abstraction + +- Platform-specific code (Linux vs Windows) belongs in + `src/platform/platform_linux.c` and `src/platform/platform_win32.c`. +- Session and backend code includes `src/platform/platform.h` and + uses `RS_PLATFORM_*` macros rather than `#ifdef __linux__` or + `#ifdef _WIN32` inline. + +### Rule B-5: Non-core surface isolation + +- Code for **Experimental** surfaces (web backend, VR, mobile) lives + in its own subdirectory and is guarded by a CMake `option()`: + `BUILD_WEB_DASHBOARD`, `BUILD_VR_SUPPORT`. +- These surfaces **must not** introduce unconditional dependencies on + the root binary; they should be additive. +- The root `make` and `cmake` default builds must succeed without + enabling non-core options. + +--- + +## Interface Contract Reference + +| Interface | Defined in | Consumer | +|---|---|---| +| Capture backend vtable | `include/rootstream.h`
