Chris LuandClaude Opus 5.5 eeb8aefe70 weed-vector: gRPC TLS to the masters and for the gateway (#12368)
* weed-vector: read the cluster's security.toml

The engine finds security.toml where weed processes do (., ~/.seaweedfs,
/usr/local/etc/seaweedfs, /etc/seaweedfs) with WEED_* environment
variables over it, and builds gRPC client and server credentials by the
rules of security.LoadClientTLS and LoadServerTLS: a dedicated client
certificate is preferred, both halves of a pair must be set, and grpc.ca
is required once either is.

* weed-vector: gRPC TLS to the masters and from the gateway

The masters are dialed with [grpc.client]'s credentials when the cluster
has them, the master's certificate checked against the host dialed or
--tls-server-name. The engine's own listener takes its identity from
[grpc.vector] and then requires a client certificate chaining to grpc.ca,
which is how the gateway, dialing with [grpc.client], reaches it. The
rustls provider is pinned before the first TLS use, as the other binaries
linking both aws-lc-rs and ring do.

* test/s3vectors: put every gRPC hop under mutual TLS in the hardened leg

VECTOR_TLS=1 now also writes [grpc.master], [grpc.volume], [grpc.filer],
[grpc.s3], [grpc.client] and [grpc.vector], and probes the master's and
the engine's gRPC ports: plaintext HTTP/2 and a client without a
certificate are refused, the client certificate gets a SETTINGS frame.

* test/s3vectors: give the test volume server 64 volume slots

Every collection grows 7 volumes and test_vector_bucket_encryption opens
two buckets while the previous test's bucket is still being torn down, so
16 slots were marginal: the Go legs failed CreateIndex now and then with
"failed to find writable volumes" and master.log showing "create 7
volume, created 4: Not enough data nodes found!".

* weed-vector: reload the listener's certificates and enforce allowed_commonNames

The listener now runs the way weed servers run theirs. The certificate, key
and CA files are re-read every WEED_TLS_CERT_REFRESH_INTERVAL (weed's
default of 5h) and on SIGHUP, and new handshakes use the changed files
without a restart; a file that no longer parses is logged and the working
configuration stays. [grpc.vector] allowed_commonNames and
grpc.allowed_wildcard_domain restrict which client certificates are served,
checked against the subject common name as security.Authenticator and the
Rust volume server's CommonNameVerifier do.

* test/s3vectors: the engine's allowlist keeps an outsider certificate out

The hardened leg sets [grpc.vector] allowed_commonNames = "localhost" and
probes the engine with a second certificate the same CA signed for
CN=outsider: the handshake must be refused, while the gateway's certificate
still gets an HTTP/2 SETTINGS frame.

* weed-vector: take the master's TLS name from the parsed endpoint

A master given without a port (https://master.example) had the whole URL
checked against its certificate.

* weed-vector: bound the master TLS handshake

connect_timeout covers only the TCP connect, so a master that accepted the
connection and never answered the handshake held up the other masters.

* weed-vector: look up security.toml keys the way viper does

An empty WEED_* variable no longer hides the file's value, and keys match
regardless of case, as for weed processes.

* weed-vector: refuse master allowlists it cannot enforce

weed checks a dialed server against allowed_server_commonNames and
allowed_server_wildcard_domain on top of grpc.ca. The engine's master dial
accepted every certificate the CA signed even when one was set; it now
fails at startup and names the key.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* weed-vector: read the master dial credentials only when given masters

A standalone engine never dials with grpc.client, so its settings no longer
stop it from starting.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* weed-vector: run each listener TLS handshake on its own task

The accept loop awaited every handshake before accepting the next
connection, so a peer that connected and sent nothing stopped every
gateway connection after it. Handshakes now run concurrently, each under a
10s timeout.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* weed-vector: read the master dial's TLS files at every dial

The client certificate, key and CA were read once at startup, so after the
files rotated a reconnect still presented the old pair. Each dial now reads
them, as the listener re-reads its own.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* weed-vector: read every unit Go durations accept in the refresh interval

WEED_TLS_CERT_REFRESH_INTERVAL values in ns, us or a leading + fell back
to five hours in the engine while weed servers honored them.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* weed-vector: fall back on a refresh interval too long to hold

An oversized WEED_TLS_CERT_REFRESH_INTERVAL panicked the engine at
startup; weed servers reject it and keep the default.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* weed-vector: refuse allowed_commonNames without the listener's certificate

With [grpc.vector] allowed_commonNames set but no cert and key, the
listener served plaintext and checked no client at all.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* weed-vector: read the master dial's credentials inside its connect timeout

The CA, certificate and key were read synchronously before the timeout
started, so a stalled credential path held up every other master.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* weed-vector: let a set key win over an empty spelling of it

With allowed_server_commonNames = "" beside allowed_server_commonnames
= "master", the lookup stopped at the empty exact match and the
allowlist went unnoticed.

Chris LuandClaude Opus 5.5 e5bc658eb7 test/s3vectors: a hardened cluster with TLS volume servers, read JWTs and encrypted chunks (#12356)
* test/s3vectors: a hardened cluster, with TLS volume servers, read JWTs and encrypted chunks

Three switches on the test cluster: VECTOR_TLS=1 puts the volume servers
behind HTTPS requiring client certificates and enables https.client for
every process; VECTOR_READ_JWT=1 gives every process a jwt.signing.read.key,
so volume reads need a token; VECTOR_ENCRYPT_VOLUMES=1 starts the gateway
with -encryptVolumeData. The integration matrix gains a hardened leg per
volume server with all three on.

* test/s3vectors: the hardened cluster proves its enforcement

Once the gateway is up, the harness checks that the hardening holds, not
only that it is configured: a TLS volume server refuses plain HTTP (Go
with HTTP 400, Rust with a TLS alert) and a connection without the client
certificate, and answers with it; under a read key an unsigned read of a
real chunk, written through the gateway and located through the filer,
gets 401.

Claude-Session: https://claude.ai/code/session_011UpvafvK8JpagF94MHWqwK

* test/s3vectors: the hardened cluster proves its chunks are encrypted

With VECTOR_ENCRYPT_VOLUMES the probe reads the stored chunk straight
from the volume server, signing the read when a read key is set, and
requires a recorded cipher key and bytes that differ from the plaintext.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* test/s3vectors: the signed probe read must return the chunk

An empty 200 passed both branches; an unencrypted read now has to return
the bytes written, and an encrypted one has to return something else.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* test/s3vectors: a read key in the caller's environment does not leak into the cluster

Only VECTOR_READ_JWT turns read JWTs on; an inherited
WEED_JWT_SIGNING_READ_KEY made the volume servers refuse the probe's
unsigned read in an encrypt-only run.

* test/s3vectors: quote certificate paths as TOML strings in security.toml

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* test/s3vectors: keep non-ASCII certificate paths as UTF-8 in security.toml

TOML has no surrogate-pair escapes, and the Rust volume server reads the
quoted value without decoding escapes at all.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* test/s3vectors: an encrypted probe chunk must not be a readable gzip stream

The gateway may gzip the body before encrypting it, so a chunk uploaded
compressed but unencrypted would differ from the body and still pass.

Chris LuandClaude Opus 5.5 54777d7fb9 vector: build weed-vector without a system protoc (#12317)
* vector: build without a system protoc

lance's build scripts run $PROTOC and fail without one. Point it at the
protoc that protoc-bin-vendored ships, at the version in Cargo.lock, so
building inside seaweed-vector/ needs only the Rust toolchain. An explicit
PROTOC still wins, and a registry without the crate falls back to PATH.

Chris Lu 4ef123d764 s3vectors: fix shared API behavior and test Go/Rust volume parity (#12216)
* s3vectors: reuse shared authenticated identity context

* s3vectors: encode empty results as arrays

* test: cover S3 Vectors with Go and Rust volume servers

* ci: require both volume implementations in vector integration tests

* s3vectors: keep identityOf as a shim over the shared identity context

Concurrent branches add identityOf call sites; deleting the helper would
break the build when they merge in either order. Route it through
GetIdentityNameFromContext so every caller resolves the same identity.

* test: wait for the vector engine to register before running

The gateway resolves weed-vector lazily through the master cluster list,
so a listening port does not mean the engine is reachable yet; the first
vector write or query could race KeepConnected and fail. Restore the
cluster.ps registration wait the previous harness had, and ignore the
pytest cache directory the suite creates.

* test: wait for master registration across OSS and enterprise

Use the exact engine registration event after AddClusterNode completes. The current enterprise cluster.ps does not list vector nodes, so waiting on its output prevents the shared fixture from starting there.

* s3vectors: keep contextWithIdentity as a shim alongside identityOf

In-flight callers still write the caller name through it; route the
write through SetIdentityNameInContext so both helpers agree on the
shared key whichever lands first.

Chris Lu 190ab32cfb vector: weed-vector registers to master; s3 discovers it there (#12146)
* vector: weed-vector registers with the weed master

weed-vector-server --masters holds a KeepConnected stream to the weed
master, the same mechanism filer and s3 use via wdclient — the server
shows up in ListClusterNodes(client_type=vector). Resends registration
and rediscovers on failure.

* vector: s3 discovers weed-vector through the master

With -vectors.grpc unset the vectors gateway resolves one registered
weed-vector via ListClusterNodes on the masters it already derives
from filer config — discovery replaces the static dial for the
single-worker OSS path. The conformance harness registers the engine
to mini's master and drops -vectors.grpc.

* vector: default-fill registration fields

..Default::default() keeps the source compiling against proto variants
that carry extra fields, so the same file works in either tree.

* vector: serve the Vectors API on the main s3 port

The vectors router sits on the main -port listener behind a dispatch
that checks the SigV4 credential scope for /s3vectors/ — no separate
port needed. -port.vectors stays for explicit dedicated-port
deployments; the conformance harness now hits vectors through :8334.

* vector: drop -port.vectors entirely

It was new — no compat to preserve. The main -port listener serves the
API whenever a weed-vector backend is reachable.

* vector: drop -vectors.grpc; discovery is the only locator

weed-vector always registers to master, the gateway always resolves it
through ListClusterNodes — a static address just forks membership.

* vector: binary is weed-vector

Matches the enterprise binary; package and lib names are unchanged.

* vector: review fixes — cluster type, grpc port, lazy resolve, leader hint, advertise

- cluster: register 'vector' as a node type so ListClusterNodes returns
  weed-vector members
- s3: dial masters via ToGrpcAddress (HTTP port + 10000)
- s3: backend resolves lazily through vectorDiscovery — workers joining
  after gateway startup work on first query, and address changes re-dial
- master_client: convert master HTTP addr to grpc +10000, honor http(s)
  scheme, follow the leader hint in KeepConnectedResponse, and
  --advertise covers wildcard/unreachable listen addresses

* vector: no --advertise flag; derive the outbound address

A wildcard listen resolves to the source IP the master sees via a
route lookup, so registration always advertises something reachable
without another flag.

* vector: review fixes — plaintext dispatch, conn leaks, discovery backoff

The two plaintext http servers now serve the vectors dispatch too —
signed s3vectors calls on the main port reach the right router.
discoverVectorWorker closes each master conn and bounds lookups to 5s;
a dead or absent worker no longer re-hits master on every RPC — the
resolver backs off for 5s between rediscovery attempts.

* vector: 1 GiB grpc cap, dead-worker invalidation, CLI rename

Valid PutVectors batches exceed the tonic 4 MiB default — match the
gateway's 1 GiB cap. A replaced worker no longer sticks: any RPC error
resets the cached address and the next call rediscovers through the
master. The core CLI bin renames to weed-vector-cli so the two crates
do not collide on the same output path.

* vector: retry-only-transport reset, periodic re-resolve, cli rename

- reset() takes the failed client and runs only on transport errors —
  an InvalidArgument on a healthy conn no longer interrupts unrelated
  requests, and a concurrent re-resolve wins the race.
- cli() re-resolves once the interval passes even with a live client,
  so a worker that moves addresses is picked up.
- verify.rs spike docs use weed-vector-cli after the bin rename.

* vector: only Unavailable counts as a transport failure

A request deadline or an application error can fire on a healthy
connection — resetting the shared conn on those churned reconnects.
