From ced1389549c56890a00d02940cb39f721103ffec Mon Sep 17 00:00:00 2001 From: Levi Neely Date: Mon, 10 Aug 2026 14:53:13 +0200 Subject: [PATCH 01/21] toolsrv: add 9P-based tool server foundation New files: - fs9p.go: FS9P struct with /proc-based execution model - /proc/new (rdwr): blocking tool execution - /proc/new.bg: background/detached execution - /proc//out, wait, stat, ctl: process management - /tools, /ctl, /info: tool registry and host info - Payload format: key=value lines, newline delimited - exec9p.go: Decoupled tool execution - ExecuteTool: standalone function for tool execution - executeSandboxed: sandbox execution without Server deps - executeBypassDirect: bypass broker without Server deps - fs9p_test.go: Unit tests for FS9P Design notes: - Background execution is the internal model - Foreground (/proc/new rdwr) blocks until completion - No per-connection state (cwd/env passed per-call or at attach) - Session ID scoping via registry, not env propagation This is the foundation - actual 9P serving and integration pending. --- session/session.go | 9 +- toolsrv/exec9p.go | 318 ++++++++++++++++++++++++ toolsrv/fs9p.go | 561 +++++++++++++++++++++++++++++++++++++++++++ toolsrv/fs9p_test.go | 216 +++++++++++++++++ 4 files changed, 1103 insertions(+), 1 deletion(-) create mode 100644 toolsrv/exec9p.go create mode 100644 toolsrv/fs9p.go create mode 100644 toolsrv/fs9p_test.go diff --git a/session/session.go b/session/session.go index e95d55f..fa0567e 100644 --- a/session/session.go +++ b/session/session.go @@ -276,7 +276,14 @@ func (s *Session) LoadTool(name string, ag *agent.Agent) error { if name == "" { return nil } - return LoadToolOnConn(s.ToolsConn(), name) + conn := s.ToolsConn() + if conn == nil { + return nil + } + // Ensure session ID is set on toolsrv before loading - the server uses this + // to scope the tool registry.

6fc7cf999b0bc16c80d89c721326461f13fb93ed Mon Sep 17 00:00:00 2001 From: Levi Neely Date: Mon, 10 Aug 2026 15:52:34 +0200 Subject: [PATCH 04/21] toolsrv: use fsedsl for namespace spec - spec9p.go: fsedsl-based namespace specification - ToolsrvCtx with Server, Agent, Proc - Handlers as package-level functions - Follows fs/spec.go pattern - server9p.go: simplified to state management only - Agent registration with HMAC tokens - BuildTree() creates fsedsl tree - Removed redundant 9P protocol handling The 9P protocol serving will use the same pattern as olliesrv (cmd/olliesrv/server.go), which takes a *fsedsl.Tree and handles all 9P message types generically. --- toolsrv/server9p.go | 690 +-------------------------------------- toolsrv/server9p_test.go | 126 +------ toolsrv/spec9p.go | 263

427cadeb299cd621bb3963dbd2a36c9fc481f5ff Mon Sep 17 00:00:00 2001 From: Levi Neely Date: Mon, 10 Aug 2026 16:48:40 +0200 Subject: [PATCH 05/21] toolsrv: remove JSON-RPC, add compat stubs for 9P transition BREAKING CHANGE: Removes all JSON-RPC toolsrv code. Deleted files: - server.go, rpcserver.go, rpcwire.go (JSON-RPC server) - conn.go, dial.go (JSON-RPC client) - exec.go, stream.go, detach.go (old execution tied to Server) - spawn.go, transport.go, processkeeper.go, remote.go (spawning) - shell_validate.go (tied to old Server) New/modified: - compat.go: Stub types to keep agent/session/fs packages compiling - Conn, Process, ProcessKeeper with TODO implementations - Spawn, SpawnRemote stubs - HostInfo, RemoteConfig, Option types - All marked TODO for 9P implementation - cmd/toolsrv/main.go: Updated to use 9P model - Requires TOOLSRV_SECRET env var - Builds fsedsl tree - serve9P placeholder for 9P protocol handling - exec9p.go: Added ToolResult types, limitedWriter, plan9Namespace The codebase compiles but toolsrv is non-functional until: 1. serve9P implements 9P protocol 2. Conn stubs are replaced with lib9p client 3.

11c67a7fb148bc1f21bb36d0b50ff9b35bcf8f03 Mon Sep 17 00:00:00 2001 From: Levi Neely Date: Mon, 10 Aug 2026 19:03:10 +0200 Subject: [PATCH 07/21] toolsrv: implement 9P Tauth authentication Replace HMAC-based registration with proper 9P Tauth flow: - First client to connect sets the secret via Tauth afid write - Server stores secret in memory, returns session token - Subsequent clients must provide matching secret - Secret never in env vars or disk, only transmitted over socket Changes: - server9p.go: Authenticate() replaces RegisterAgent/GetAgent - client9p.go: Dial() does Tauth handshake (write secret, read token) - spawn.go: generates secret, no longer passes via TOOLSRV_SECRET env - auth9p.go: simplified to just GenerateSecret() - spec9p.go: removed /register file, token validation at connection level - cmd/toolsrv/server.go: handleAuth/handleAuthWrite/handleAuthRead Security model: - Session generates secret on Spawn() - All agents share session's secret via ProcessKeeper - Socket permissions (local) or SSH (remote) protect transport - Secret dies with toolsrv process, new secret on respawn Added integration tests verifying: - First connection sets secret - Reconnect with same secret works - Wrong secret rejected - ProcessKeeper reconnect/respawn behavior - Concurrent connections --- agent/agent_test.go | 51 +--- cmd/toolsrv/main.go | 15 +-
