The transitional references land in one commit, because they are only correct
together: the repository is pgsty/silo, its default branch is main, and nothing
in the tree should point a user at the old names.
Changed:
- Workflow branch filters. go.yml and vulncheck.yml gated on `branches: master`
for both push and pull_request, so renaming the default branch would have
taken automatic CI offline with no error and no signal - the workflows would
simply never trigger again. They now name main.
- Release target. goreleaser's `release.github.name` becomes silo, which is
what actually decides where a tagged build publishes. sign-release-rpms.sh's
GH_REPO default follows.
- The OCI `image.source` label, the Helm chart `sources` entry, the security
advisory link in the issue-template config, and the go.mod comment citing the
LDAP TLS fix.
- 115 occurrences across README, README_ZH, SECURITY, CONTRIBUTING and 30 docs
pages, including 72 links that also carried the master branch in their path.
Those matter most: GitHub redirects clone, fetch, push and web URLs after a
rename, but raw.githubusercontent.com does not, and neither follows a branch
rename - every one of those links would 404 twice over.
- Three error strings in cmd/erasure-sets.go, cmd/storage-errors.go and
internal/config/errors.go that print an issue URL to operators. These are Go
string literals inside rebrand-guard's brand allowlist, so the baseline is
regenerated. The regeneration removes exactly those three entries and adds
none; all twelve other protected sets, including the 9014 exported symbols,
are byte-identical.
- The transitional-naming disclaimers in README, README_ZH, SECURITY and
CONTRIBUTING are dropped, since they no longer describe anything.
Deliberately unchanged, all three because they exist to reject or freeze the old
name rather than to point at it:
- buildscripts/minio-upgrade.sh pins pgsty/minio@sha256:b6bfe72... - the frozen
pre-rebrand image is the control group for the MinIO-to-Silo upgrade test.
- helm-migration-guard rejects any rendered container still pulling pgsty/minio.
- verify-rebrand.sh rejects the same in the delivery surfaces.
Also unchanged: docs/config/README.md links to pgsty/mc/blob/master, and that
repository's default branch really is still master. It moves when mc does.
verify-rebrand.sh gains three assertions so this cannot silently regress: no
source reference may name pgsty/minio outside the three allowlisted guards, no
link may target pgsty/silo's master branch, and go.yml and vulncheck.yml must
filter on main. Both new rejections were negative-tested - reintroducing a
master branch filter and adding a pgsty/minio URL each fail the gate with the
specific message.
This commit assumes the rename actually happens. Until the GitHub branch and
repository renames are executed, the links it introduces do not resolve.

Two coupled changes that must land together, because the same files carry both:
the server now identifies itself as Silo, and every path that would have called
home to a MinIO-operated service is closed.
Product identity
- build-constants.go: store name, UA name and startup banner become Silo. The
Go identifiers (MinioStoreName, MinioBannerName, ...) keep their names on
purpose - renaming exported symbols would churn the compatibility surface for
a cosmetic gain, and the rebrand guard freezes that surface.
- main.go, server-startup-msg.go, ftp-server.go and the user-visible log, help
and error strings across cmd/ and internal/ switch to Silo. Original MinIO
copyright, LICENSE, NOTICE and CREDITS are untouched; --version now prints
the upstream copyright, the pgsty modification notice, and the trademark
policy's approved "based on MinIO technology" attribution.
- api-headers.go: the HTTP Server header becomes "Silo". This is the one
externally observable identity change, so TestCommonHeadersUseSiloProductName
pins it - probes that sniff for "MinIO" must move to capability detection.
- Prometheus metric HELP strings keep their MinIO wording. They are part of the
metrics contract the guard protects, not product copy.
Configuration directory
- config-dir.go: new installs use ~/.silo. If only ~/.minio exists it is still
read, with a one-time notice and no files moved. If both exist ~/.silo wins
and an ambiguity warning is emitted; an explicit --config-dir always wins.
Covered by TestSelectDefaultConfigDir. The internal .minio.sys layout is
never renamed - this rule applies to the user config directory only.
Upstream service lockdown
- globalInplaceUpdateDisabled is now true at initialization rather than being
set from MINIO_UPDATE. common-main.go still parses MINIO_UPDATE so upgrading
nodes do not fail on an unknown key, but warns that the value is ignored;
there is no way to re-enable the updater. TestInplaceUpdateCannotBeEnabled
guards that. Without this, an admin with mc could have overwritten
/usr/bin/silo with an upstream MinIO binary.
- verifyBinary and commitBinary refuse early; the ServerUpdate v1/v2 admin
routes and the peer-rest update endpoints stay registered and keep returning
the existing programmatic error, so clients see a stable failure rather than
a 404.
- MinioReleaseBaseURL and defaultMinisignPubkey are emptied: no dl.min.io
download root, and upstream's minisign key is no longer a trust root for
anything this fork ships.
- cmd/callhome.go is deleted and internal/config/subnet/ is reduced to parsing
its old keys and reporting that the integration is disabled. config-current.go
warns instead of failing when callhome or SUBNET settings are present, so an
upgraded node with those keys still starts.
- internal/config/errors.go replaces the MinIO Slack and support entry points
with Silo documentation and issue links. Error codes and programmatic fields
are unchanged.
Verified: the compatibility baseline is unchanged except for the deliberate
removal of the /api/health/upload SUBNET route; go build, go vet and the full
cmd/ and internal/ unit suites pass; a locally built binary starts, serves
S3/Admin/metrics on the unchanged /minio/* routes, answers with Server: Silo,
and falls back to a pre-existing ~/.minio with the expected notice.

GetNotifyNATS reads user_credentials, nkey_seed and tls_handshake_first
and GetNotifyAMQP reads immediate, but none of them were registered in
DefaultNATSKVS/DefaultAMQPKVS or the help schema, so CheckValidKeys
rejected any enable=on target carrying them. Worse, the legacy config
migration wrote exactly these keys - including the env var name
MINIO_NOTIFY_NATS_USER_CREDENTIALS used as a config key, because the
NATSUserCredentials constant doubled as both - so a migrated NATS config
failed validation on every load, and the FetchEnabledTargets fail-fast
then silently disabled all bucket notification targets.
- Register user_credentials/nkey_seed/tls_handshake_first (NATS) and
immediate (AMQP) in the default KVS and help schema; split
NATSUserCredentials into a real config key plus EnvNATSUserCredentials
(all env var names byte-stable)
- Fix legacy migration: SetNotifyNATS writes the proper key;
SetNotifyAMQP no longer writes cfg.Immediate under the internal key
and now carries both immediate and internal
- Tolerate the legacy MINIO_NOTIFY_NATS_USER_CREDENTIALS key written by
pre-fix migrations (NATS-scoped, load path only) with fallback read;
env > user_credentials > legacy key
- Print key names only, never values, in the invalid-keys error of both
CheckValidKeys forms; rejected values can carry credentials
- Add an AST-based audit test asserting parser reads, migration writes
and help entries stay within the registered key set for all ten notify
subsystems, with floor assertions so collector drift fails loudly
- Document (unchanged) FetchEnabledTargets fail-fast and pin it with a
characterization test
Known same-class gap left in place and pinned by the audit's allowlist:
SetNotifyPostgres/SetNotifyMySQL write five unregistered DSN-era keys;
tracked for a follow-up issue.

The address MinIO attributes a request to is read from X-Forwarded-For,
X-Real-IP or RFC 7239 Forwarded, and never from the connection unless all
three are absent. It becomes aws:SourceIp and the audit remotehost field,
so any client that can reach the API port chooses the value an IpAddress
condition is evaluated against and the address every logged action is
attributed to.
MINIO_API_TRUSTED_PROXIES now selects who may make that claim:
unset the historical behaviour, unchanged
none no forwarded header is believed; the TCP peer wins
<CIDRs> believed only from listed peers, chains read right-to-left
Reading right-to-left is what makes an appending proxy safe: each hop
appends the peer it actually saw, so an entry a client injected can only
sit to the left of one a proxy wrote. The stock nginx recipe
$proxy_add_x_forwarded_for appends, which leaves the client's entry
left-most - exactly where the untrusted path reads - so a deployment with
no direct route to the API port was forgeable too.
_MINIO_API_XFF_HEADER is deliberately untouched, in semantics and in read
timing. Widening it to mean "trust nothing" was implemented and reverted:
it is the only part of this change that could alter a deployed
configuration, and the new variable expresses the same guarantee at no
compatibility cost. Upstream's TestXFFDisabled is retained verbatim.
Notes on the allow-list mode, all covered by tests:
- it must name proxies, not the subnet they sit in; listed entries are
skipped while walking, so a range covering clients lets them forge
- a cluster must list its own nodes, because MinIO forwards between
them and a client can force a hop via the ListObjectsV2 token
- loopback is trusted as a peer, not as a chain entry, so FTP and SFTP
keep attributing their sessions
- the node-to-node forwarder drops X-Real-IP and Forwarded from a peer
not entitled to have set them
- the walk scans the header in place and stops after 100 hops, so a
long chain costs neither allocation nor unbounded work
No behaviour change for any deployment that does not set the new
variable: the untrusted path is a verbatim copy of the previous function
body, differentially verified against it over ~5.1M header combinations.
The LDAP STS allow-list now shares the list parser as pure code motion,
verified identical across every combination of 37 allow-list values and
21 peer addresses.

Remove the per-username LDAP STS throttle bucket and keep the limiter keyed only by source IP. A username bucket is shared across all clients and lets one source keep a known account's bucket drained with bad-password attempts, locking the legitimate user out before LDAP bind.
For trusted proxies, stop trusting the left-most forwarded address. Resolve X-Forwarded-For right-to-left, skip trusted proxy hops, reject catch-all trusted-proxy CIDRs, and intentionally ignore RFC 7239 Forwarded for this security-sensitive bucket. Document that X-Real-IP is trusted verbatim and must be overwritten by the trusted proxy, not passed through from clients.
Update focused limiter, source-IP, trusted-proxy, and LDAP config tests to cover source-only buckets, spoofed appended XFF, multi-hop trusted proxies, Forwarded fallback, catch-all rejection, and the X-Real-IP deployment contract.

Update the STS, security, select, and Docker documentation to reflect the recent hardening work, including LDAP STS throttling details, OIDC JWT verification changes, and the new pgsty-specific security policy and advisory index.
Rewrite repository and raw-document links that still pointed at minio/minio so the docs consistently reference pgsty/minio instead.
The core idea is to keep the documentation aligned with the fork's actual security behavior, ownership, and upgrade guidance without mixing in unrelated code changes.
Prevent LDAP STS reservation cancel paths from over-crediting rate-limit buckets by capping refill and refund capacity against in-flight reservations.
Add an explicit trusted-proxy allowlist for LDAP STS source bucketing, prefer clean X-Real-IP values on trusted peers, and extend tests/docs for the new behavior.
Prevent username enumeration in AssumeRoleWithLDAPIdentity by returning the same external STS error for unknown users and invalid passwords, while preserving LDAP infrastructure failures as upstream errors so they continue to surface as 500s and remain visible in server logs.
Add a small in-memory rate limiter for LDAP STS login attempts, keyed by source IP and normalized username, and add regression coverage for auth failure classification, throttling, and Docker-backed LDAP end-to-end flows.

Close the OIDC JWT algorithm confusion flaw in AssumeRoleWithWebIdentity by restoring a JWKS-only verification path. Stop injecting the client secret into the verifier keyring and restrict accepted signing methods to the asymmetric algorithms already supported by the existing JWKS flow.
Add regression coverage to verify HS256 tokens are rejected, RS256 tokens remain valid, and JWKS refresh and retry logic cannot bypass the method allowlist.

Commit b6eb8dff64 renamed compression
setting environment variables to follow consistent style.
Although it preserved backward compatibility for the most part (i.e. it
handled MINIO_COMPRESS_ALLOW_ENCRYPTION, MINIO_COMPRESS_EXTENSIONS, and
MINIO_COMPRESS_MIME_TYPES), MINIO_COMPRESS_ENABLE was left behind.
Additionally, due to incorrect fallback ordering, and DefaultKVS
containing enable=off allow_encryption=off (so kvs.Get should've been
tried last), that commit broke MINIO_COMPRESS_ALLOW_ENCRYPTION (even
though it appeared to be handled), and even older MINIO_COMPRESS, too.
The legacy MIME types and extensions variables take precedence over both
config and new variables, so they don't need fixing.
`go run golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest -fix -test ./...` executed.
`go generate ./...` ran afterwards to keep generated.
This commit removes FIPS 140-2 related code for the following
reasons:
- FIPS 140-2 is a compliance, not a security requirement. Being
FIPS 140-2 compliant has no security implication on its own.
From a tech. perspetive, a FIPS 140-2 compliant implementation
is not necessarily secure and a non-FIPS 140-2 compliant implementation
is not necessarily insecure. It depends on the concret design and
crypto primitives/constructions used.
- The boringcrypto branch used to achieve FIPS 140-2 compliance was never
officially supported by the Go team and is now in maintainance mode.
It is replaced by a built-in FIPS 140-3 module. It will be removed
eventually. Ref: https://github.com/golang/go/issues/69536
- FIPS 140-2 modules are no longer re-certified after Sep. 2026.

These are needed checks for the functions to be un-crashable with any input
given to `msgUnPath` (tested with fuzzing).
Both conditions would result in a crash, which prevents that. Some
additional upstream checks are needed.

This commit replaces the LDAP client TLS config and
adds a custom list of TLS cipher suites which support
RSA key exchange (RSA kex).
Some LDAP server connections experience a significant slowdown
when these cipher suites are not available. The Go TLS stack
disables them by default. (Can be enabled via GODEBUG=tlsrsakex=1).
fixes https://github.com/minio/minio/issues/20214
With a custom list of TLS ciphers, Go can pick the TLS RSA key-exchange
cipher. Ref:
```
if c.CipherSuites != nil {
return c.CipherSuites
}
if tlsrsakex.Value() == "1" {
return defaultCipherSuitesWithRSAKex
}
