This commit adds a section to the master key documentation
describing how to generate a random 256 bit master key.
Further this commit adds a warning that master keys are not
recommended for production systems because it's (currently)
not possible to replace a master key (e.g. in case of compromise).
By default when we listen on all interfaces, we print all the
endpoints that at local to all interfaces including IPv6
addresses. Remove IPv6 addresses in endpoint list to be
printed in endpoints unless explicitly specified with '--address'
This commit adds an auto-encryption feature which allows
the Minio operator to ensure that uploaded objects are
always encrypted.
This change adds the `autoEncryption` configuration option
as part of the KMS conifguration and the ENV. variable
`MINIO_SSE_AUTO_ENCRYPTION:{on,off}`.
It also updates the KMS documentation according to the
changes.
Fixes#6502
Currently we use GetObject to check if we are allowed to list,
this might be a security problem since there are many users now
who actively disable a publicly readable listing, anyone who
can guess the browser URL can list the objects.
This PR turns off this behavior and provides a more expected way
based on the policies.
This PR also additionally improves the Download() object
implementation to use a more streamlined code.
These are precursor changes to facilitate federation and web
identity support in browser.
One user reported having discovered the following error:

Hence, adding support of different xml encoding. Although there
is no clear specification about it, even setting "GARBAGE" as an xml
encoding won't change the behavior of AWS, hence the encoding seems
to be ignored.
This commit will follow that behavior and will ignore encoding field
and consider all xml as utf8 encoded.
Currently we would end up considering common prefix
buckets to be part of the same DNS service record,
which leads to Minio server wrongly forwarding the
records to incorrect IPs.
This refactors the vault configuration by moving the
vault-related environment variables to `environment.go`
(Other ENV should follow in the future to have a central
place for adding / handling ENV instead of magic constants
and handling across different files)
Further this commit adds master-key SSE-S3 support.
The operator can specify a SSE-S3 master key using
`MINIO_SSE_MASTER_KEY` which will be used as master key
to derive and encrypt per-object keys for SSE-S3
requests.
This commit is also a pre-condition for SSE-S3
auto-encyption support.
Fixes#6329
This PR implements one of the pending items in issue #6286
in S3 API a user can request CSV output for a JSON document
and a JSON output for a CSV document. This PR refactors
the code a little bit to bring this feature.
guessIsRPCReq() considers all POST requests as RPC but doesn't
check if this is an object operation API or not, which is actually
confusing bucket forwarder handler when it receives a new multipart
upload API which is a POST http request.
Due to this bug, users having a federated setup are not able to
upload a multipart object using an endpoint which doesn't actually
contain the specified bucket that will store the object.
Hence this commit will fix the described issue.
registering notFound handler more than once causes
gorilla mux to return error for all registered paths
greater than > 8. This might be a bug in the gorilla/mux
but we shouldn't be using it this way. NotFound handler
should be only registered once per root router.
Fixes#6915
When MINIO_PUBLIC_IPS is not specified and no endpoints are passed
as arguments, fallback to the address of non loop-back interfaces.
This is useful so users can avoid setting MINIO_PUBLIC_IPS in docker
or orchestration scripts, ince users naturally setup an internal
network that connects all instances.
This commit renames the env variable for vault namespaces
such that it begins with `MINIO_SSE_`. This is the prefix
for all Minio SSE related env. variables (like KMS).
clientID must be a unique `UUID` for each connections. Now, the
server generates it, rather considering the config.
Removing it as it is non-beneficial right now.
Fixes#6364
When migrating configs it happens often that some
servers fail to start due to version mismatch etc.
Hold a transaction lock such that all servers get
serialized.
