backlog#1052 S3, third slice — the hard blocker for a second embedded
server's service stage. GLOBAL_BUCKET_METADATA_SYS was a process-global
OnceLock whose init ran .set().unwrap(): a second instance's service
startup panicked the whole process. The system it guards is inherently
per-store (it holds the store handle and that store's bucket→metadata
cache), so it now lives on the store's own InstanceContext:
- init_bucket_metadata_sys writes the cell of the store it was handed
(api.ctx) — no signature change — and keeps the double-init fail-fast,
now scoped to the instance (assert on the per-context set). The
dist-erasure check for the refresh loop reads the same context.
- get_global_bucket_metadata_sys / the crate-private getter behind the
~20 get_*_config helpers resolve through the current_ctx() facade —
the published store's context, or bootstrap before that — so every
existing reader keeps its exact single-instance behavior.
- New acceptance test: two real stores in one process each initialize
their own metadata system (the old global cell panicked right there),
plus a shared builder extracted from the store-graph test.
201 bucket/metadata regression tests green.
* refactor(app): give each context's server-config handle its own copy
backlog#1052 S3, first slice: establish the per-context state pattern on
the smallest subsystem. ServerConfigHandle was a unit struct forwarding
both get and set to the process-global GLOBAL_SERVER_CONFIG, so every
AppContext shared one config regardless of which context a caller held.
The handle now keeps its own copy: a set lands on the owning context and
on the process global (ambient readers — the config loader path, the
scanner — keep working), and a get prefers the owned copy, falling back
to the global while the initial load still publishes there. Single
instance: the owned copy and the global are written together, so reads
are unchanged. Two contexts that both published stay isolated even though
the shared global only remembers the last write (covered by a new test).
The global write in set() is the transitional bridge for ambient readers;
it goes away when those readers migrate and multi-instance flips on
(backlog#1052 S5).
* refactor(notify): hand out the notification system as an owned Arc
backlog#1052 S3, second slice. GLOBAL_NOTIFICATION_SYS stored the
NotificationSys by value and every accessor returned
Option<&'static NotificationSys> — a process-lifetime borrow that a
per-server AppContext can never hold. The global now stores an Arc and
the accessor chain (ecstore runtime sources, ECStore::notification_system,
the iam forwarders, the rustfs shims, NotificationSystemInterface and the
AppContext resolvers) hands out owned Arcs instead.
Call sites are unchanged apart from two borrow adjustments in the
rebalance admin handler (pass &Arc where a reference is expected; borrow
with as_ref() so the handle survives to the second use). Behavior is
identical — same single global instance, first init still wins — but the
type now permits a future per-server context to own its notification
system (backlog#1052 S3 follow-up).
backlog#1052 S2, second slice: admin request dispatch.
Admin operations are registered as &'static dyn Operation, so unlike FS
they cannot carry per-server state. Instead, the (per-server) S3Router now
holds the server's ServerContextSlot and injects it into every request's
extensions at both dispatch points (check_access and call) — the same
extensions channel already used for ReqInfo/RemoteAddr.
- make_admin_route binds the slot; the HTTP builder passes the same slot
the S3 service (FS) uses, so both paths dispatch to the same server.
- admin/runtime_sources gains object_store_from_req / an extensions-based
variant for handlers that have already moved request fields out; both
fall back to the ambient process context when no slot was injected
(direct handler tests, non-router paths) — single-instance unchanged.
- 27 handler resolution sites across 12 files now resolve per-request;
helper functions without request access (11 sites: site_replication
state helpers, quota/table_catalog internals, object_zip_download
workers) stay on the ambient path until app subsystems become
per-server (backlog#1052 S3).
- One site (site-replication resync) resolves before the request body is
consumed, keeping the original error precedence.
New test: the router injects its slot into request extensions by pointer
identity. Embedded e2e (basic S3 + deferred-IAM recovery) still green.
Two follow-up fixes to #4607 (both verified real bugs, each with a regression
test):
1. The in-call server_info retry did not re-dial on network errors. A
network-like first failure runs through `finalize_result`, which sets the
client's `offline` gate; the retry then called `evict_connection` and
re-invoked `server_info`, but `get_client` short-circuits on that gate and
returns "temporarily offline" without dialing. Only the async recovery
monitor would clear it. So the retry re-dialed only in the timeout branch and
was a no-op in the transport/half-open branch it was meant to cover. Add
`PeerRestClient::prepare_retry` (evict + clear the offline gate) and use it
before the retry.
2. Synthesized/degraded drive lists went empty on hostname deployments.
`PeerRestClient::host` is an `XHost` that `hosts_sorted` builds via
`XHost::try_from` -> `to_socket_addrs`, so it is the resolved `IP:port`; but
`synthesized_disks`/`peer_disk_health` compared it against
`Endpoint::host_port()`, which is the raw `hostname:port`. On hostname
clusters the compare missed, the drive list came back empty, and
`unknownDisks` stayed 0 — reproducing the "drives vanish from the summary"
regression #4607 fixed (also affected the pre-existing offline path). Compare
through a shared `endpoint_host_matches` helper that canonicalizes the
endpoint side through the same `XHost` resolution.
Tests: `peer_rest_client_prepare_retry_clears_offline_gate`,
`endpoint_host_matches_direct_and_canonicalized` (uses localhost, no external
DNS).
Follow-up to rustfs/rustfs#4607; tracked in rustfs/backlog#1049.

fix(ecstore): read the persisted SSE-C nonce in the GET decrypt resolver
#4576 moved SSE-C encryption to a random per-encryption nonce persisted
in object metadata and taught the rustfs-layer decrypt resolver to read
it back — but the byte-level GET decryption resolves its material in
crates/ecstore object_api/readers.rs, a duplicated twin that still
recomputed the deterministic legacy nonce. Encrypt with the random
nonce, decrypt with the deterministic one: the first AEAD block fails
and every SSE-C GET aborts its body after the response headers
(IncompleteRead(0 bytes) on clients; all 8 SSE-C cases in the
implemented s3-tests whitelist), which is what has been driving the
"S3 Implemented Tests" CI job into its 60-minute timeout since
2026-07-09.
Resolve the base nonce like the encrypt side: prefer the persisted IV
(x-rustfs-encryption-iv, then the case-insensitive MinIO interop key),
fall back to the deterministic nonce only for legacy objects with no
stored IV or an undecodable value. Full implemented s3-tests whitelist
is back to 451 passed / 0 failed against the fixed binary.
* feat(helm): support multiple server pools for capacity expansion
The server already understands multiple pools (RUSTFS_VOLUMES is split on
spaces, one pool expression each; rc admin pool/expand/rebalance/
decommission exist), but the chart could only render a single StatefulSet.
Add an opt-in pools mode:
- pools.enabled=false (default) renders byte-identical output to the
current chart (verified against five values variants)
- pools.list renders one StatefulSet per entry; entries may set
replicaCount (4 or 16) and a storageclass block, everything else is
inherited from the top-level values
- pool 0 keeps the legacy StatefulSet/pod/PVC names and its (immutable)
selector, so existing single-pool deployments can be expanded in place
without renaming or data loss; additional pools render as
<fullname>-poolN with a rustfs.com/pool label in their selector
- RUSTFS_VOLUMES and RUSTFS_SERVER_DOMAINS enumerate every pool
- pod anti-affinity is scoped per pool so pools may share nodes while
each pool still spreads its own pods across distinct nodes
- template validation fails fast on unsupported replicaCount, an empty
pools.list, or pools in standalone mode
- pools are append-only by design (list index = identity), documented in
values.yaml and the README
* fix(helm): truncate pool names DNS-safely, document PDB pool scope
Truncate <fullname>-poolN to 63 chars by shortening the base name rather
than the suffix, so the pool index always survives and two pools of a
max-length release cannot collide. Document that the single
PodDisruptionBudget deliberately spans all pools.
* fix(helm): pool-mode anti-affinity must be preferred, not required
Found by live-testing in-place expansion on a 5-node cluster (4-replica
pool 0 + 4-replica pool 1): with requiredDuringScheduling anti-affinity
the expansion deadlocks in a cycle that cannot self-heal -
1. the not-yet-rolled pool-0 pods still carry the unscoped required
rule and repel every rustfs pod from their nodes, so part of pool 1
stays Pending (no IP, no headless-DNS record);
2. every pod that already has the new RUSTFS_VOLUMES exits fatally on
'failed to lookup address information' for those Pending peers;
3. the StatefulSet rolling update is gated on the crashing pod going
Ready, so the remaining pool-0 pods never roll and keep repelling.
Because StatefulSets assign revisions per ordinal, even a subsequent
template fix cannot rescue a wedged rollout (Pending ordinals are only
recreated with the new template after the higher ordinals go Ready) -
the new pool's StatefulSet has to be recreated. Shipping the soft
affinity from the start avoids the state entirely; expansion was
re-tested end-to-end with it and converges.
Pool-mode rendering only - pools.enabled=false still renders the
existing required anti-affinity byte-identically.

test(e2e): align object-lock overwrite tests with AWS new-version semantics
PR #3179 made put-like writes (PUT, CopyObject, multipart create/complete)
on versioned object-lock buckets create a new version instead of being
blocked by the current version's legal hold or COMPLIANCE retention, which
is the correct AWS behavior. Six e2e assertions in object_lock_test.rs
still encoded the old blocking semantics and, because e2e_test is excluded
from the CI test run, stayed red unnoticed since 2026-06-03.
Verified against a real server built from current main: all six failed at
their "should be blocked" assertions. Rewritten to assert the AWS
contract: the write succeeds with a distinct new version id, the new
content is current, the protected version keeps its content and lock
metadata, and version-targeted deletion of the protected version stays
blocked (for COMPLIANCE even with bypass_governance). Full object_lock
module is green again (33/33).
PR #4468 removed the last use of wildmatch (crates/notify swapped it for a
hand-rolled star-only glob matcher), but the workspace dependency declaration
in the root Cargo.toml was left behind as an orphan. cargo shear flags it as
not used by any workspace member. Drop the stray line.
Also refresh the comments in crates/notify/src/rules/pattern.rs that still
referred to the removed wildmatch crate, so they describe the current
hand-rolled matcher instead of a dependency that no longer exists.

fix(admin): report unreachable info members as `unknown` with balanced drive counts
`GET /rustfs/admin/v3/info` synthesizes an entry for every peer, but a peer
whose properties RPC failed below the offline threshold with no cached snapshot
was reported as `initializing` with an empty drive list. That drive list being
empty meant its drives disappeared from the backend summary entirely, so
`onlineDisks + offlineDisks` no longer equaled `totalDrivesPerSet` (an operator
sees `onlineDisks: 3, offlineDisks: 0` for a 4-drive set), and `initializing` is
a misleading state for a member that has been running for hours — it reads like
a node was ejected when nothing is wrong (upstream rustfs/rustfs#4566).
Changes:
- madmin: add `ItemState::Unknown` ("unknown") and an `unknownDisks` bucket on
`ErasureBackend` (serde `default`, so older payloads still deserialize).
- ecstore diagnostics: `get_online_offline_disks_stats` now returns a third
`unknown` bucket instead of folding those drives into `offline`, keeping
`online + offline + unknown == totalDrivesPerSet`.
- ecstore notification_sys: a probe miss below the failure threshold with no
cache is now reported as `unknown` (not `initializing`) and carries the host's
drives from the pool topology (tagged `unknown`) so the summary stays balanced;
drive synthesis is factored into `synthesized_disks(host, endpoints, state)`,
shared by the offline and unknown paths.
Tracked in rustfs/backlog#1049 (P1-A + P0-A).

* feat(utils): make DNS resolver cache TTL configurable via RUSTFS_DNS_CACHE_TTL_SECS
The resolver cache in crates/utils/src/net.rs had a hardcoded 300s TTL with
no way to tune or disable it. On orchestrated networks (Docker Swarm,
Kubernetes) a peer's DNS name is its only durable identity while its container
IP changes on reschedule, and the platform DNS always serves the current
answer. A fixed 300s application-side cache can keep a member dialing a dead IP
for up to five minutes after a peer restarts. Rust has no runtime DNS cache, so
on musl images this was the only cache in the stack and the only one that could
not be turned off.
Read the TTL from RUSTFS_DNS_CACHE_TTL_SECS (u64, default 300), matching the
existing RUSTFS_INTERNODE_* transport knobs. `0` disables caching entirely so
every get_host_ip consults the system resolver. The resolved value is logged
once at first use, removing an invisible cache from the triage surface. Change
is backward-compatible and confined to net.rs.
Also drop the two per-lookup info! logs on the resolve path: they would flood
the log when caching is disabled and added hot-path noise otherwise.

fix(ecstore): emit CommonPrefix for object with same-named prefix in non-recursive listings (backlog#1042)
On single-disk / consistent deployments a non-recursive scan_dir that finds a/xl.meta classifies `a` as an object and does not descend, so the source never emits the prefix `a/`, dropping the CommonPrefix from delimiter listings even when `a/b` exists. This is the single-disk follow-up to backlog#880 (the multi-disk merge path was fixed in #4563).
Fix: in the scan_dir Ok branch, for a non-recursive listing of a plain object, probe whether `a/` holds a listing entry other than the object itself (new object_prefix_has_sibling_listing_entry, reusing directory_has_visible_listing_entry and skipping the object's own xl.meta and data dirs); if so, additionally schedule the prefix dir `a/`. The upstream fold in from_meta_cache_entries_sorted_infos already emits object `a` as Contents and dir `a/` as a CommonPrefix, so nothing changes there. Leaf objects (the common case) pay a single list_dir and return false immediately.
Verification: new scan_dir unit test (positive: `a` + `a/b` coexist; negative: leaf `c` produces no spurious `c/`); new end-to-end e2e (object `a` + `a/b` with delimiter "/" -> Contents `a` + CommonPrefix `a/`); existing list_objects_duplicates e2e (#1797 / #2439 regressions) stays green; set_disk::read 114 passed.
Note: lib-test compilation depends on #4573 (now merged), which added the allow_inplace_legacy_fallback argument to the codec streaming arity tests after #4560 / backlog#879.

The three store::bucket::tests::bucket_delete_* tests drive make_bucket /
delete_bucket through the process-global local-disk registry
(GLOBAL_LOCAL_DISK_MAP) and lock client, and through Sets::new which reads the
process-global erasure mode. Under `cargo test` (single process, many threads)
they race other global-touching tests and fail deterministically with
InsufficientWriteQuorum.
serial_test's #[serial] with the crate default key serializes them across the
in-process suite. Measured at --test-threads=16: baseline fails all three every
round; with #[serial] all three pass every round. nextest's per-test processes
are covered separately by the ecstore-serial-flaky test-group in
.config/nextest.toml (#4558). Full instance-level isolation remains a backlog
#939 (InstanceContext) concern and is not attempted here.

fix(rustfs): sanitize user-metadata in metadata=true object listing (#2743)
The console listing path (`list-type=2&metadata=true`) serializes each
object's user-metadata key as a raw XML *element name* and its value as
XML text without validation. User-metadata keys derived from HTTP
headers can legally contain characters that are illegal in an XML `Name`
(space, `$`, `%`, `#`, a leading digit, control bytes), and values can
contain C0 control characters that are illegal in XML 1.0 text.
A single object carrying such a key or value produced a malformed
`ListBucketResult` document, which the console's XML parser rejected
wholesale — so every object under that prefix vanished from the Web UI,
while plain `ListObjectsV2` (which never serializes user metadata) kept
working. The breakage appeared the moment any one object in a prefix had
XML-unsafe metadata and cleared once that object was removed, matching
the report.
Guard the serialization in `ObjectMetadataExtension::serialize_content`
(shared by the list-objects and list-versions metadata outputs): skip
entries whose key is not a valid XML element name, and strip
XML-1.0-illegal control characters from values. A single poison object
can no longer corrupt the whole listing document.
fix(ecstore): only evict remote lock channel on transport failures (#4567)
The remote lock RPC path evicted the cached gRPC channel on *any*
`tonic::Status`. Genuine transport failures (connect refused/reset,
keepalive/deadline) surface that way, but so do server-produced
application statuses on a perfectly healthy channel: `Unauthenticated`
/`PermissionDenied` from the signature interceptor, `Internal`
/`FailedPrecondition` when the peer lock service is not ready yet,
`InvalidArgument`, `ResourceExhausted`, `Unimplemented`, and so on.
Evicting the channel for those cannot help — the channel is fine — and
each spurious eviction re-dials the connection and advances the peer
toward the offline threshold via `record_peer_unreachable`, producing
background channel churn on an otherwise healthy cluster.
Classify the tonic status with `is_transport_failure` (underlying
transport source present, or one of `Unavailable`/`DeadlineExceeded`
/`Unknown`/`Cancelled`) and only evict the cached channel when it is a
real transport failure. The client-side timeout arm still evicts. This
mirrors the transport-vs-application distinction already used on the
remote-disk RPC path.
* refactor(ecstore): migrate the background-services cancel token into InstanceContext (Phase 5 Slice 13)
Phase 5 Slice 13 (backlog#939): move the background-services cancellation token
out of the process static into the per-instance InstanceContext, so cancelling
one instance's background workers (scanner/heal/tier/lifecycle) no longer
touches another instance.
- InstanceContext gains `background_cancel_token: OnceLock<CancellationToken>`
with `init_background_cancel_token` (set-once) and `background_cancel_token()`
returning an owned clone.
- global.rs `init_/get_/create_/shutdown_` helpers keep their signatures and
route through the current instance's context; the static is removed. The
getter now returns an owned `Option<CancellationToken>` instead of a
`Option<&'static _>`, which is what lets the token live in the context.
- Callers adapt to the owned token: the metadata-refresh loop drops `.cloned()`;
the lifecycle worker/loops take the owned token (a shared fallback is cloned
when the token is somehow uninitialized). No Arc cycle is introduced —
workers hold a token clone, not the instance context.
Single-instance behavior is unchanged: startup creates one token in the
bootstrap context the ECStore adopts, and shutdown cancels that same token.
Tests: the token is set-once and cancelling one instance's token leaves a
distinct instance uninitialized.
Verification: cargo test -p rustfs-ecstore (23 instance-context tests green),
cargo clippy -p rustfs-ecstore --all-targets (clean), make pre-commit (pass).

* test(ecstore): prove multi-instance isolation; document embedded guard retention (Phase 5 Slice 14) (#4588)
Phase 5 (backlog#939) capstone. The prior 13 slices moved every piece of
per-instance runtime state out of process globals into ECStore's
InstanceContext. This slice proves the result and records the remaining work.
- Add `two_instances_isolate_all_migrated_state`: an end-to-end acceptance test
that constructs two independent InstanceContexts and verifies NONE of the
migrated state is shared — erasure setup, lock manager, region, deployment id,
the four service handles (tier/notifier/expiry/transition), the local disk
registry, the bucket monitor, and the background cancel token. This is the
object-graph isolation carrier working end to end.
- Document why the embedded single-instance guard (EMBEDDED_SERVER_STARTED) is
intentionally retained: storage startup still publishes into the process-level
bootstrap context (write-once region/endpoints/deployment id) and the single
GLOBAL_OBJECT_API handle, so a second startup would fail-fast on that shared
state. Lifting the guard requires threading a per-instance context through
startup — a follow-up beyond migrating the globals. The guard is NOT removed:
rejecting the second start is safer than the panic it would otherwise become.
Verification: cargo test -p rustfs-ecstore (acceptance test + all instance-context
tests green), cargo clippy -p rustfs-ecstore --all-targets (clean), make
pre-commit (pass).
Refs: backlog#939 (Phase 5, Slice 14). Stacked on Slice 13 (#4586).
The internode HTTP/2 window/keepalive tuning (apply_http_client_tuning +
http2_keep_alive_* in build_http_client) only takes effect when the connection
negotiates HTTP/2, which happens via TLS-ALPN. Over plaintext internode
transport the connection is HTTP/1.1 and all the tuning is silently inert,
with no signal to the operator.
Make this honest without changing protocol behavior (no h2c, no
prior_knowledge, no opt-in flag):
- InternodeHttpClientTuning gains h2_tuning_explicit, true when the operator
set a window size, a non-default tuning profile, or the keepalive env.
- Add pure predicate should_warn_h2_inert(negotiated_is_http2,
h2_tuning_explicit, already_warned) and maybe_warn_h2_inert, gated by a
process-lifetime AtomicBool so the warn fires at most once.
- Call maybe_warn_h2_inert at both record_internode_http_version sites using
the actual negotiated resp.version().
- Document the TLS-ALPN requirement at apply_http_client_tuning and near the
ENV_INTERNODE_HTTP2_* constants.
Tests cover the should_warn_h2_inert truth table and that h2_tuning_explicit
reflects explicit windows and a non-default profile.
fix(server): count in-flight HTTP requests with an RAII guard (backlog#806-35)
The active-requests gauge was maintained with tower-http TraceLayer hooks:
on_request (+1), on_response (-1) and on_failure (-1). With the default
ServerErrorsAsFailures classifier a 5xx response fires BOTH on_response and
on_failure, so every 5xx decremented the gauge twice (net -1); a streaming
200 that failed mid-body did the same. The gauge drifted downward and
saturated at zero, corrupting the readiness busy-protection signal
(alias_busy_threshold_exceeded).
Replace the hook arithmetic with an InFlightGuard (RAII): InFlightLayer wraps
each request future, incrementing on entry and decrementing exactly once when
the future resolves (any status) or errors/cancels. Removed the +1 from both
on_request hooks and the -1 from trace_on_response and both on_failure hooks,
keeping their tracing and failure-metric work intact. Applied to both the
external and internode stacks.
Added a test driving the layer for 2xx, 5xx and a no-response service error,
asserting the gauge nets to zero in every case (the 5xx path is the fix).
fix(ecstore): age LastMinuteLatency samples individually (backlog#806-16)
The rolling one-minute latency window stored bare Duration samples plus a
single, never-updated start_time. Its retain predicate ignored the element
and evaluated the constant now.duration_since(start_time) < 60s, so once the
window had existed for 60s every add() dropped ALL samples and the average
degenerated to the latest single sample.
Each sample now carries its own Instant and is retained by its individual
age. The type backs only in-memory EpHealth + admin display (the wire shape
is target::LatencyStat with curr/avg/max), so Serialize/Deserialize is kept
only to satisfy the enclosing LatencyStat derive; the sample Instant is
serde(skip) and restarts aging on reload.
fix(io-metrics): drop client-controlled bucket label from rustfs_s3_operations_total (backlog#806-22)
The bucket dimension on the rustfs_s3_operations_total counter is
client-controlled and unbounded, letting any client explode metric
cardinality (a Prometheus/OTEL cardinality DoS that grows the in-process
OTEL aggregation store even without a scrape). Drop the bucket label so the
series is keyed by the bounded op dimension only (<=122 variants), matching
MinIO which never labels its default operation counters with bucket.
BREAKING: rustfs_s3_operations_total no longer carries a "bucket" label.
record_s3_op(op, bucket) -> record_s3_op(op); all call sites in
rustfs/src/storage/{ecfs.rs,helper.rs} updated (bucket bindings retained
where still used by audit/notify paths). Add metrics-util debugging recorder
dev-dep and tests asserting the series carries only the op label and that
series count equals distinct-op count.
DeleteServiceAccount looked up the target service account and, on any
get_service_account error OTHER than not-found (e.g. a stored-credential decode
error), set svc_account = None and continued. The non-admin owner guard then
used svc_account.is_some_and(|v| v.parent_user != user), which is FALSE for a
None target, so the guard was skipped and the code fell through to the delete —
a non-owner could delete a service account whose stored credential failed to
decode (authz bypass, fail-open).
Extract a fail-closed helper non_admin_may_delete_service_account(caller, target)
that returns true only when the target loaded AND is owned by the caller; a None
target (unverifiable ownership) or an owner mismatch now denies. Admins (holding
RemoveServiceAccount) are unaffected. + unit test.

fix(rio): typed-first internode HTTP error classification (backlog#805)
classify_reqwest_error matched reqwest/hyper error text by English
substrings, brittle to library/OS-locale wording. Refactor to a pure,
testable classify_transport_error(err, is_timeout, is_connect, is_body)
that trusts structured signals first: caller timeout, then the io::Error
kind found anywhere in the source chain (typed wins over any string/body
signal so a real ConnectionRefused is never mislabeled DnsResolutionFailed),
then a DNS-only string heuristic gated behind is_connect, then body, then
Unknown.
Flip DnsResolutionFailed to retryable, mirroring MinIO IsNetworkOrHostDown
(*net.DNSError => network-or-host-down => retryable); RustFS already retries
transient DNS at endpoints.rs, and bounded retries cost at most one extra
attempt on permanent NXDOMAIN.
Swap the ecstore remote_disk non-retryable exemplar from DnsResolutionFailed
to Unknown accordingly.
Add a default-on multi-role adversarial validation policy to the root
AGENTS.md (risk tiers, six reviewer roles, findings protocol, exit
criteria), a shared adversarial-validation skill with repo-specific
attack probes grounded in shipped bugs, seven audit fixes to the root
instruction files, and an actionlint gate for workflow changes.
In the default (non-rio-v2) build, SSE-C encrypted with AES-256-GCM using a deterministic nonce derived from MD5("{bucket}-{key}"), and decrypt recomputed it. Overwriting the same object under the same SSE-C key reused an identical (key, nonce) pair, breaking AES-GCM confidentiality and integrity. The base nonce was never persisted.
Generate a fresh random 12-byte nonce for every single-PUT and multipart session, persist it under both x-rustfs-encryption-iv and the MinIO interop key, and resolve it from stored metadata on decrypt and multipart part encryption. Objects written before this change carry no stored IV and fall back to generate_ssec_nonce, so existing objects still decrypt.

fix(object-capacity): harden clock handling in write window, background intervals and scope registry
Three low-severity robustness gaps (S32+S33+#35):
- WriteRecord keyed its 60-bucket write window by wall-clock unix
seconds while the debounce used Instant. An NTP step backwards marked
recent buckets as future and silently suppressed write-triggered
refreshes until the wall clock caught up; a forward step aged the
whole window at once. Bucket keys now derive from a monotonic
per-record epoch, immune to clock steps.
- Background refresh/metrics intervals were only clamped at zero;
RUSTFS_CAPACITY_SCHEDULED_INTERVAL=u64::MAX overflowed
Instant + Duration and panicked the spawned task, silently killing
scheduled refreshes. Intervals now clamp into [1s, 30 days] via one
helper with a structured warn.
- record_capacity_scope merged new disks into an expired entry and
refreshed its recorded_at, resurrecting a scope take_capacity_scope
would have discarded (and the merge path never pruned). Expired
entries are now replaced, not merged into.

(alpha/beta/rc tags previously overwrote the stable pointer with
release_type "stable"); drop the placeholder .asc files; build the
Linux targets only on main pushes (tags/schedule/dispatch keep the
full matrix); remove the unreachable --build clause and a needless
full-history clone
- ci.yml: event-scoped concurrency so merges stop cancelling the
weekly scheduled run; drop the redundant skip-duplicate-actions
gate job; run clippy before tests; trim the unused toolchain from
the typos job
- ci-docs-only.yml (new): satisfy the required "Test and Lint" check
on docs-only PRs that ci.yml skips via paths-ignore
- audit.yml: drop cargo-audit (cargo-deny advisories covers the same
RustSec database); same event-scoped concurrency fix
- docker.yml: job-level short-circuit for per-merge dev builds; send
the Trivy SARIF to code scanning; unify the upload-artifact pin
- performance-ab.yml: add concurrency; only re-run on labeled events
when the added label is perf-ab
- stagger the Sunday crons (build 01:00, audit 03:00,
nix-flake-update 05:00, mint 06:00)
- delete performance.yml: disabled since 2025-07; idle-server
profiling, no benchmark baseline, stale ecstore package name
fix(metrics): normalize peer-health key so servers_offline_total counts each peer once
rustfs_cluster_servers_offline_total is the count of distinct keys in the
addr-keyed CLUSTER_PEER_HEALTH map. The data path keys a peer by
endpoint.grid_host() (scheme://host:port) while the lock path keys it by
url::Url::to_string() (scheme://host:port/, trailing slash), so one physical
peer becomes two health entries and a single downed node reports 2 (2N for N).
Normalize the address (trim trailing slashes) at the map boundary in
record_peer_reachable/record_peer_unreachable/cluster_peer_is_offline/
cluster_peer_should_bypass so both forms collapse to one canonical key.
Pure observability fix; peer selection and quorum are unchanged.

The tracker never influenced traversal: walkdir's follow behavior is
fixed up front by follow_links(), and should_follow() only gated the
tracker's own bookkeeping. Its 'depth limit' compared tree depth (not
symlink chain depth), so RUSTFS_CAPACITY_MAX_SYMLINK_DEPTH was a
complete no-op while its telemetry claimed symlinks were skipped that
walkdir had in fact followed and counted; record_symlink was always
called with size 0, so tracked_bytes never left zero (S12).
Remove the tracker, its skipped/summary events, the symlink metric and
the depth env knob end to end (the env's 'as u8' truncation goes with
it), and document the real semantics at the walker: follow_links(true)
counts targets with walkdir's ancestor-loop detection breaking cycles,
follow_links(false) — the default — counts no symlink targets. The scan
root itself is pre-resolved since backlog#1015.

PR #4560 added a 15th parameter (allow_inplace_legacy_fallback) to
build_codec_streaming_part_reader while the negative arity tests from a
concurrently developed branch still call it with 14 arguments — the two
changes merged cleanly textually but broke the workspace test build on
main (E0061 in set_disk/read.rs), failing CI for every open PR.
Pass false at both call sites: these tests assert Err outcomes
(oversized part, missing quorum) that are independent of the fallback
mode, and false preserves the historical whole-request fallback
semantics used by eager first-part reads.
