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.

`go run golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest -fix -test ./...` executed.
`go generate ./...` ran afterwards to keep generated.
This change uses the updated ldap library in minio/pkg (bumped
up to v3). A new config parameter is added for LDAP configuration to
specify extra user attributes to load from the LDAP server and to store
them as additional claims for the user.
A test is added in sts_handlers.go that shows how to access the LDAP
attributes as a claim.
This is in preparation for adding SSH pubkey authentication to MinIO's SFTP
integration.
When minio runs with MINIO_CI_CD=on, it is expected to communicate
with the locally running SUBNET. This is happening in the case of MinIO
via call home functionality. However, the subnet-related functionality inside the
console continues to talk to the SUBNET production URL. Because of this,
the console cannot be tested with a locally running SUBNET.
Set the env variable CONSOLE_SUBNET_URL correctly in such cases.
(The console already has code to use the value of this variable
as the subnet URL)
This change adds a `Secret` property to `HelpKV` to identify secrets
like passwords and auth tokens that should not be revealed by the server
in its configuration fetching APIs. Configuration reporting APIs now do
not return secrets.
* Add periodic callhome functionality
Periodically (every 24hrs by default), fetch callhome information and
upload it to SUBNET.
New config keys under the `callhome` subsystem:
enable - Set to `on` for enabling callhome. Default `off`
frequency - Interval between callhome cycles. Default `24h`
* Improvements based on review comments
- Update `enableCallhome` safely
- Rename pctx to ctx
- Block during execution of callhome
- Store parsed proxy URL in global subnet config
- Store callhome URL(s) in constants
- Use existing global transport
- Pass auth token to subnetPostReq
- Use `config.EnableOn` instead of `"on"`
* Use atomic package instead of lock
* Use uber atomic package
* Use `Cancel` instead of `cancel`

The earlier approach of using a license token for
communicating with SUBNET is being replaced
with a simpler mechanism of API keys. Unlike the
license which is a JWT token, these API keys will
be simple UUID tokens and don't have any embedded
information in them. SUBNET would generate the
API key on cluster registration, and then it would
be saved in this config, to be used for subsequent
communication with SUBNET.
