Chris LuandClaude Opus 5.5 b9bc42c217 s3vectors: vend write credentials to index data only to the vector engine and Lance worker (#12316)
* security: share the filer admin token check

CheckGrpcAdminPeer verifies an admin Bearer token inline. Move the check
into IsFilerAdminToken so an HTTP endpoint can accept the same token.

* lance: recognize the cluster's own components by a signed token

A request whose X-Seaweedfs-Cluster-Token header carries an admin token
signed with jwt.filer_signing.key comes from a component that holds the
cluster key: the vector engine or the Lance maintenance worker. Mark such
a request as trusted. It still authenticates as an identity, which stays
the principal for vended credentials. A dedicated header leaves the
Authorization header to Lance OAuth clients. A gateway with no key
trusts no one.

* lance: vend write credentials to a vector bucket's indexes only to trusted callers

An index in a vector bucket's vector namespace is also a Lance table, so
a caller granted s3tables:UpdateTable could describe it, or declare it
again, and get credentials that write the index data without passing the
vector bucket policy. In that namespace both now vend read-only
credentials unless the caller is trusted, and a declare from anyone else
no longer writes the dataset markers.

* lance worker: prove the cluster key to the Lance namespace

The gateway now vends write credentials to a vector bucket's indexes only
to callers that send a token signed with jwt.filer_signing.key. The
worker already takes that key for the admin stream; its namespace client
now mints a token from it for every catalog request.

* weed-vector: describe the index the gateway created and prove the cluster key

CreateIndex declared a table the gateway had just created, which only
worked because declare is idempotent. Describe it instead. The Lance
namespace vends write credentials to a vector bucket's indexes only to
callers that send a token signed with jwt.filer_signing.key, so take the
key with --filer-signing-key, the same flag the Lance worker has.

* lance worker: keep the cluster key out of Debug output

* lance: answer a declare of an existing table with its own location

CreateTable succeeds for a name that already exists without looking at
the location requested, and declare kept using that location for the
dataset markers and the vended credentials. Declaring an existing table
with another table's location, such as a vector index, got credentials
to that table's data. Use the location the catalog holds, which
CreateTable now also reports for a new table.

* lance: sign cluster tokens with a key derived for the catalog

A cluster token was a filer admin token signed with jwt.filer_signing.key
and, by default, never expired. Sent to the Lance namespace on every
request, often over plain HTTP, a captured one would also authorize the
filer's IAM service. Sign it with a key derived from the cluster key for
this one use, which the admin services do not accept, and mint it with a
five minute lifetime. weed-vector drops its token lifetime flag.

* lance: follow a reloaded jwt.filer_signing.key

The Lance namespace copied the cluster key at startup. A SIGHUP reload
refreshes the gateway's filer guard but not that copy, so after a key
rotation the restarted vector engine and worker were no longer trusted.
Read the key from the guard on every check.

* iceberg: keep a vector bucket's indexes read-only

An index in a vector bucket is also a catalog table the Iceberg REST
catalog loads, and LoadTable vended credentials that could write it to
any caller granted s3tables:UpdateTable. A commit staged its metadata
file in the index directory on the same grant. Apply the vector
namespace rule to both, after the caller's own UpdateTable check.

* iceberg: confine a created table's location to its namespace before writing

Stage-create skips the registration that confines a location to the
table's namespace, yet vends write credentials for that location. A
caller allowed to create a table in any namespace of a bucket could name
another namespace's prefix, a vector index included, and get write
credentials to it. The non-staged create also wrote its first metadata
file there before the registration refused the location.

* lance: a declare that finds an existing table answers like describe

Creating a name that already exists is idempotent, so a caller allowed
only to create tables could declare someone else's table and get write
credentials to it, and clear its deregistered marker. Describe would have
vended that caller read-only credentials. A declare now looks the name up
first; when it only finds the table, writing needs UpdateTable, as it does
for describe.

Chris LuandClaude Opus 5.5 e2826c48bd s3tables: make the vector namespace of a vector bucket read-only (#12292)
* s3tables: make the vector namespace of a vector bucket read-only

S3 Vectors authorizes index operations against the vector bucket policy,
but an index is also a catalog table in the bucket's "vector" namespace,
and the S3 Tables API only checks s3tables grants. A caller the vector
policy denies DeleteIndex could still delete the index, and its data,
with DeleteTable.

Untrusted writes that name the vector namespace of a LANCE bucket now run
behind a fence that passes filer reads and refuses filer writes. The
operation's own checks still answer everything short of a write, so a
caller without the grant gets its usual denial and learns nothing about
the bucket, and a CreateTable that finds the index already there, which
is what the vector engine's declare does, still succeeds. A refused write
answers 403 AccessDenied. Trusted callers (the gateway, the shell) are
unaffected, and so is a namespace named vector in an Iceberg bucket.

* lance: refuse register and deregister in a vector bucket's vector namespace

Every catalog write the Lance namespace makes goes through the S3 Tables
handler and its vector namespace fence, but register over an existing
table at the same location and deregister only add or remove a marker
file in the dataset directory. Check the vector namespace before those
writes, after the table read that already gates them.

* s3tables: refuse deferred creates in a vector bucket's vector namespace

Manager.AuthorizeCreateTable gates the Iceberg create paths that write
metadata into the table bucket before the catalog registers the table.
Those writes never pass the handler's fence, so the gate applies the same
read-only rule once the caller's own create permission is confirmed.

* s3tables: let a declare of an existing index past the vector namespace fence

The vector engine declares every index the gateway has just created, and
that CreateTable only reaches its idempotent path. Upstream that path
writes nothing, so the fence never trips, but a build whose idempotent
path repairs table state would refuse the engine. Decide the exception
up front instead: a CreateTable naming a finished index in the vector
namespace runs unfenced, while a new name or an unfinished create stays
fenced.
