Swift container and account metadata handlers cloned the cached
BucketMetadata, set the tagging fields, and called set_bucket_metadata,
which only updates the in-memory cache map. Nothing reached
.metadata.bin, so every Swift metadata POST was lost on restart and
silently overwritten by the next disk-truth reload (a peer
LoadBucketMetadata notification or the 15-minute refresh loop) — while
the client had already been told 2xx.
Route these writes through a new metadata_sys::update_config_with: a
read-modify-write that loads the on-disk metadata and persists the
result under the same write guard metadata_sys::update uses, so the
rewrite merges against disk truth instead of a possibly stale cache and
cannot clobber a concurrent update to another config file. Peers are
notified afterwards, matching the S3 config handlers.
Persisting these writes required hardening the paths that now produce
durable state:
- Account metadata writes validate account ownership. This metadata
holds the account's TempURL signing key, so an unauthenticated write
for someone else's account would have become a durable, cluster-wide
takeover of that account's pre-signed URLs. Reads stay open because
TempURL signature validation runs before credentials exist.
- disable_versioning verifies the container exists. Without it the
metadata loader's "no metadata on disk" default would be persisted,
creating an orphan metadata file and caching a fabricated default as
authoritative.
- Container and account metadata are size- and count-limited, reusing
the Swift limits object metadata already enforces; these tags land in
the bucket metadata file that every later config write rewrites whole.
- A rewrite refuses to run when the persisted tagging config is
unreadable, instead of merging onto an empty set and wiping the
container ACL and versioning tags. It reports 409 naming the remedy.
- Storage errors are logged in full and reported generically, since they
now carry real disk and quorum detail.
The tagging arm of BucketMetadata::update_config also clears the parsed
config, as the lifecycle arm does: parse_all_configs skips empty XML
rather than clearing, so a cleared config kept serving the old tags.
Tagging is serialized with the S3 XML serializer the loader can parse
back, not quick_xml, whose output was never round-trippable.
* chore(deps): tighten crate dependency features
Narrow Tokio and dependency feature declarations for protocols, TLS runtime, utils, targets, and replication based on direct crate usage.

* chore(deps): trim hyper-rustls features
Keep direct hyper-rustls features aligned with the actual RustFS call sites. rustfs-targets only needs native root loading and the rustls provider/TLS policy features for MQTT TLS config construction, while rustfs-ecstore needs the HTTP connector protocol features but not webpki roots.

* chore(deps): remove redundant dependency features
Remove manifest feature entries that are implied by other requested features in the same dependency declaration.
Verified that the resolved Cargo feature graph is unchanged after the cleanup.

Move workspace-level dependency feature lists into the member crates that consume each dependency while keeping required default-features flags at the workspace root.
Also refresh starshard to 2.2.2 via cargo update and cargo upgrade --exclude ratelimit.

The FTPS and WebDAV authentication handlers compared the client-supplied secret
key against the stored secret with `String::eq`, which short-circuits on the
first differing byte. A network attacker who knows (or enumerates) a valid
access key can recover the secret key byte-by-byte via response-timing analysis;
neither path is rate limited.
Switch both to a constant-time comparison using `subtle::ConstantTimeEq`, the
same primitive the SFTP handler and `rustfs/src/auth.rs::constant_time_eq`
already use. `subtle` is added to the `ftps` and `webdav` feature dependency
sets (it was previously gated on `sftp` only).
Addresses GHSA-3p3x-734c-h5vx.
Drop the [target.'cfg(target_os = "linux")'.dependencies] tokio
"io-uring" feature from 6 crates and the rustfs binary. Because
.cargo/config.toml enables --cfg tokio_unstable globally, this feature
switched every Linux build's file I/O onto tokio's io_uring runtime
backend. Restricted Linux environments (Docker default seccomp, gVisor,
proot, old kernels) reject io_uring_setup with EACCES/ENOSYS, which
tokio surfaced as PermissionDenied and RustFS reported as
DiskAccessDenied at startup.
Add scripts/check_no_tokio_io_uring.sh so the feature cannot silently
return: it fails on any tokio dependency line enabling "io-uring", while
still allowing a future application-level io-uring crate dependency.
Wire it into make pre-commit/pre-pr/dev-check and CI.

The session watchdog now selects its detection method per
platform. It previously probed kernel TCP state through a
Linux-only procfs path, so on macOS every healthy idle session
was killed within a minute, and on Windows the watchdog never
spawned at all, leaving wedged sessions with no cleanup. Linux
keeps its fast-kill watchdog unchanged. Other platforms get a
silence-only backstop that kills a session only at the
documented 30-minute idle ceiling.
The host-key loader now has a Windows arm. It loads OpenSSH
format host keys from the configured directory and logs a
one-time warning to restrict NTFS ACLs on the key directory,
the same operator-managed approach FTPS, WebDAV, KMS, and IAM
already use on Windows. Startup previously aborted with
UnsupportedPlatform because the Unix mode-bit permission check
has no Windows equivalent. tokio's io-uring feature is now
enabled only in Linux builds. io-uring is a Linux kernel
interface and enabling it unconditionally broke the Windows
build.
