Chris LuandClaude Opus 5.5 5063aa9be2 weed-vector: check master certificates against the server allowlists, read -config_dir (#12374)
* weed-vector: look for security.toml in -config_dir first

weed processes search the directory -config_dir names before ., so a
cluster keeping security.toml there left the engine in plaintext.
--config-dir (also -config_dir, WEED_VECTOR_CONFIG_DIR) does the same.

* weed-vector: dial the masters the way weed clients do

The master's certificate must chain to grpc.ca and is not checked against
the host dialed, as weed clients verify (advancedtls.CertVerification), so
masters sharing one workload certificate, or dialed by IP, register as
they do from weed. Instead, grpc.client.master_allowed_server_commonNames,
grpc.client.allowed_server_commonNames or grpc.allowed_server_commonNames
(and the wildcard domain likewise) restrict which server identities are
accepted: the common name or a DNS SAN, or an exact URI SAN, as
security.Authenticator.AuthenticateServer does. These used to be refused
at startup; --tls-server-name is gone with the host check.

The TLS runs in a connector that reads the credentials asynchronously at
every dial, so the connect timeout still covers the reads, the TCP connect
and the handshake together. An IPv6 master's brackets are stripped before
the dial.

* test/s3vectors: the hardened leg allowlists server identities for grpc.client

The gateway and the engine then accept only servers named localhost, which
exercises the engine's allowed_server_commonNames check on the master dial.

* weed-vector: parse the refresh interval with time.ParseDuration's arithmetic

The interval was summed in floating-point seconds, so 0.9ns rounded up to
1ns where Go truncates it to 0 and falls back to the 5h default, 0.3s was
off by a nanosecond, and 3000000h was accepted where Go rejects anything
past the longest time.Duration. Each part is now an integer count of
nanoseconds plus the fraction Go adds, with Go's overflow bounds, and the
value is no longer trimmed, as Go does not trim it either.

* weed-vector: test a master dial whose credential read stalls

The bounded-dial tests passed no credentials or a prebuilt endpoint, so
moving the credential read out of the connect timeout would have failed
none of them. The new test points grpc.ca at a FIFO nobody writes.

* weed-vector: dial a closed port in the stalled credential read test

Against a silent listener, a dial that never read the credentials timed
out with the same message, so the test passed without the read. Nothing
listens on the port now, so only the stalled read can time out.

* weed-vector: test that Security::load searches the config dir

Only candidates() was tested, so load dropping config_dir on the way
would have passed.

* weed-vector: expand a leading ~ in -config_dir like weed's ResolvePath

* weed-vector: hold the port in the stalled credential read test

A released port can be taken before the dial, and a dial that skipped the
read would then time out and pass. A listener that drops every connection
keeps the port and still fails such a dial at once.

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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.
