The package defines the Server type and its namespace — 'fs' was a
leftover name from when it only held the filesystem spec. Now it's
the server definition. File renamed spec.go → server.go to match.
- Move toolsrv logic into internal/{fs,exec,registry} packages to match
olliesrv's structure. server.go (9P protocol) stays at top level.
- Deduplicate parseKV/parsePayload: remove dead code from old spec9p.go,
single implementation in internal/fs/parse.go.
- Add structured logging via log/slog (replaces fmt.Fprintf to stderr).
- Standardize qid path hashing to fnv.New64a (matches olliesrv).
- Fix toolsrv process leaks:
- Add Pdeathsig to local spawn so toolsrv dies when olliesrv exits.
- Add idle timeout (30s with no connections after first client seen).
- ProcessKeeper.Dial() kills old process before respawning.
- Pass session ID via --session-id flag (not env var) so tool registry is configured when olliesrv spawns toolsrv
- /tools now returns JSON array with full ToolInfo including InputSchema (fixes Bedrock validation error requiring type: object)
- Implement SpawnRemote: deploy ~/.config/ollie via tarball over SSH, set XDG_CONFIG_HOME so tools/*.meta are found on remote
- Add --no-auth flag for debugging Tauth issues
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
- server.go: Full 9P2000 protocol handling
- version, auth, attach, walk, open, read, write, clunk, stat
- Uses fsedsl.Tree for all operations
- Handles directories and files
- Supports rdwr files (RequestRespMode)
- main.go: Remove placeholder serve9P, use new implementation
The toolsrv binary now serves a working 9P filesystem with the
namespace defined in toolsrv/spec9p.go:
/register, /ctl, /tools, /proc/*, /info
