* fix(credentials): keep secrets out of match and YAML parse errors
A match that fails to parse is no longer quoted in the Parse error, since
it may be a URL with a token in it. Userinfo is detected before the scheme
check, so ftp://user:token@host is refused as userinfo, and a match with a
query string or fragment is refused because it can never apply and a query
string is where signed URLs carry their token. Every YAML decode error is
now redacted, not only type errors: quoted scalars such as a secret under a
mismatched !!int tag are replaced and unquoted map keys are cut off.

* fix(downloads): make auth errors name the real cause and never retry unresolved secrets
AuthError now appends its cause, so a registry's DENIED or UNAUTHORIZED
detail reaches the operator. HTTP auth errors print only the status text in
place of the cause, because the downloader builds that cause from the
requested URL, which can carry a signed query string. Registry pulls say
that docker config credentials were tried too, and a download that carried
a caller-provided credential (WithBearerToken, or an explicit authorization
on gallery reads) reports that credential as rejected instead of blaming
the store.
The Range probe for a leftover partial file now returns an unresolved
secret as a permanent error, like the download request already did.

* fix(credentials): keep oras pulls anonymous on a broken docker helper and close bodies
When docker config names a credsStore helper that cannot run, the oras
credential func now logs at debug and returns no credential, so public
pulls keep working as they did before the adapter existed. The transport
closes the request body when a rule's secret cannot be resolved, as the
RoundTripper contract requires. The redirect spec now uses a custom header
rule on the origin, which net/http would not strip on its own, to prove the
transport does not carry credentials to the next hop.

* test(oci): cover FetchImageBlob authentication against a private registry
FetchImageBlob now has a spec that pulls a layer blob by digest from a
basic-auth registry through the oras credential adapter, and one that shows
the same fetch fails when no rule matches. oras only speaks HTTPS here, so
the registry serves TLS and the spec points http.DefaultTransport, which
retry.DefaultClient falls back to, at the test server's client for its
duration instead of adding a transport seam to production code.

* docs(credentials): document auth error wording, ollama manifests and registry tokens
The errors section now lists the registry and provided-credential messages
and says the server's reason is appended. ollama:// manifests are fetched
without credentials, so only blob downloads use the file. GHCR, Docker Hub
and Quay need basic auth with the token as password, and match rules must
not carry a query string or fragment. The backend gallery docs and the
container troubleshooting section now point to the private sources page.

quay.io redirects blob downloads to pre-signed S3/Akamai URLs that
expire after about 10 minutes. On a slow connection a multi-GiB
backend layer cannot finish inside that window, so the connection
drops mid-stream on every attempt. The retry added for #10577
restarted each attempt from byte zero, which replayed the same
failure until the budget ran out and the install failed with
"unexpected EOF".
A retry now keeps the bytes already on disk and re-requests the
blob with "Range: bytes=N-". Each request goes back to the
registry, so it gets a fresh redirect URL and auth token. The
retry budget only counts attempts that made no forward progress,
so a slow link that keeps advancing keeps downloading. A resumed
file is spliced from separate responses and bypasses the digest
check in layer.Compressed(), so the assembled file is re-verified
against the layer digest before it is trusted; on a mismatch the
download starts over through the verified reader.
Fixes#10577

* fix(backends): fall back to copying links when the filesystem rejects symlinks (#10890)
Backend installation extracts the OCI image tar via containerd's
archive.Apply, which calls os.Symlink directly. On filesystems that do
not support symlinks (notably CIFS/SMB mounts, commonly used to back the
/backends volume) the syscall fails with "operation not supported" and
the whole install aborts, leaving an empty backend directory. The CUDA
llama.cpp image trips this on the libcublas.so -> libcublas.so.12.x
symlink.
When archive.Apply fails with a link-unsupported error, reset the
staging directory and re-extract with a pure-Go walker that still
attempts real symlinks/hardlinks first and degrades to copying the link
target's contents in place when the filesystem rejects them.
mutate.Extract already flattened the layers, so the tar carries no
whiteouts to interpret. Link copies are deferred to a second pass so
forward references resolve.

* fix(oci): reject path-traversal tar entries in the link-copy fallback
safeJoin sanitized "../.." entries by clamping them under root instead of
rejecting them, so a malicious entry was silently redirected rather than
refused. Join without the leading-slash trick and reject any entry whose
cleaned path resolves outside root; absolute link targets are still mapped
under root (image-root relative) rather than escaping.

* fix(oci): silence gosec on the validated link-copy file ops
Use hdr.FileInfo().Mode() instead of converting the int64 tar mode to
os.FileMode (removes two G115 overflow findings), and annotate the tar
extraction file operations with justified #nosec comments: every path is
validated by safeJoin against the extraction root before use (G304/G305).

* fix(oci): build extraction image from downloaded layers
Avoid appending downloaded layers to the original remote-backed image, which duplicates the layer stack and reopens the source during extraction. Building from an empty image preserves the flattened whiteout semantics while keeping extraction local.

* fix(oci): materialize chained links in dependency order
Retry deferred link copies until their targets exist so soname chains work on filesystems without symlink support. Document that copied links can increase backend storage usage on CIFS and SMB mounts.

Installing large backend images (e.g. vLLM/vLLM-omni, several GiB) over
the Web UI could fail with "failed to download layer 0: unexpected EOF"
when a single connection to the registry dropped mid-stream. The whole
install then failed with no recovery, and since the download is not
resumable, retrying from the UI restarted from zero and usually hit the
same blip again - so users saw it as a consistent, size-correlated
failure (issue #10577).
The registry transport already retries manifest/digest fetches via
defaultRetryPredicate (GetImage/GetImageDigest), but the per-layer data
stream in DownloadOCIImageTar bypassed it entirely: layer.Compressed()
+ xio.Copy ran exactly once.
Extract the per-layer copy into downloadLayerToFile, which retries on the
same transient errors (unexpected EOF, EOF, EPIPE, ECONNRESET, connection
refused) with exponential backoff, truncating any partial data before
each retry. Non-retryable errors and context cancellation still fail
fast.

LocalAI pulls models from OCI registries (via go-containerregistry), the
Ollama registry, and OCI blob stores (via oras), but every request went
out with the underlying library's generic User-Agent, so registry
operators had no way to attribute traffic to LocalAI.
Add an oci.UserAgent() helper that returns "LocalAI" (or
"LocalAI/<version>" when the binary is built with a version stamp via
internal.Version) and wire it into all three pull paths:
- pkg/oci/image.go: remote.WithUserAgent on the go-containerregistry
image and digest requests
- pkg/oci/ollama.go: a User-Agent header on the Ollama manifest request
- pkg/oci/blob.go: a LocalAI User-Agent on the oras blob client. This
mirrors oras' auth.DefaultClient (same retry.DefaultClient policy);
only the advertised User-Agent changes.
Implements #6258.

* feat: add backend versioning data model foundation
Add Version, URI, and Digest fields to BackendMetadata for tracking
installed backend versions and enabling upgrade detection. Add Version
field to GalleryBackend. Add UpgradeAvailable/AvailableVersion fields
to SystemBackend. Implement GetImageDigest() for lightweight OCI digest
lookups via remote.Head. Record version, URI, and digest at install time
in InstallBackend() and propagate version through meta backends.
* feat: add backend upgrade detection and execution logic
Add CheckBackendUpgrades() to compare installed backend versions/digests
against gallery entries, and UpgradeBackend() to perform atomic upgrades
with backup-based rollback on failure. Includes Agent A's data model
changes (Version/URI/Digest fields, GetImageDigest).
* feat: add AutoUpgradeBackends config and runtime settings
Add configuration and runtime settings for backend auto-upgrade:
- RuntimeSettings field for dynamic config via API/JSON
- ApplicationConfig field, option func, and roundtrip conversion
- CLI flag with LOCALAI_AUTO_UPGRADE_BACKENDS env var
- Config file watcher support for runtime_settings.json
- Tests for ToRuntimeSettings, ApplyRuntimeSettings, and roundtrip
* feat(ui): add backend version display and upgrade support
- Add upgrade check/trigger API endpoints to config and api module
- Backends page: version badge, upgrade indicator, upgrade button
- Manage page: version in metadata, context-aware upgrade/reinstall button
- Settings page: auto-upgrade backends toggle
* feat: add upgrade checker service, API endpoints, and CLI command
- UpgradeChecker background service: checks every 6h, auto-upgrades when enabled
- API endpoints: GET /backends/upgrades, POST /backends/upgrades/check, POST /backends/upgrade/:name
- CLI: `localai backends upgrade` command, version display in `backends list`
- BackendManager interface: add UpgradeBackend and CheckUpgrades methods
- Wire upgrade op through GalleryService backend handler
- Distributed mode: fan-out upgrade to worker nodes via NATS
* fix: use advisory lock for upgrade checker in distributed mode
In distributed mode with multiple frontend instances, use PostgreSQL
advisory lock (KeyBackendUpgradeCheck) so only one instance runs
periodic upgrade checks and auto-upgrades. Prevents duplicate
upgrade operations across replicas.
Standalone mode is unchanged (simple ticker loop).
* test: add e2e tests for backend upgrade API
- Test GET /api/backends/upgrades returns 200 (even with no upgrade checker)
- Test POST /api/backends/upgrade/:name accepts request and returns job ID
- Test full upgrade flow: trigger upgrade via API, wait for job completion,
verify run.sh updated to v2 and metadata.json has version 2.0.0
- Test POST /api/backends/upgrades/check returns 200
- Fix nil check for applicationInstance in upgrade API routes

We can't use the mutate.Extract written bytes as current status as that
will be bigger than the compressed image size. Image manifest don't have
any guarantee of the type of artifact (can be compressed or not) when
showing the layer size.
Split the extraction process in two parts: Downloading and extracting as
a flattened system, in this way we can display the status of downloading
and extracting accordingly.
This change also fixes a small nuance in detecting installed backends,
now it's more consistent and looks if a metadata.json and/or a path with
a `run.sh` file is present.
