This commit adds a new method `UpdateKey` to the KMS
interface.
The purpose of `UpdateKey` is to re-wrap an encrypted
data key (the key generated & encrypted with a master key by e.g.
Vault).
For example, consider Vault with a master key ID: `master-key-1`
and an encrypted data key `E(dk)` for a particular object. The
data key `dk` has been generated randomly when the object was created.
Now, the KMS operator may "rotate" the master key `master-key-1`.
However, the KMS cannot forget the "old" value of that master key
since there is still an object that requires `dk`, and therefore,
the `D(E(dk))`.
With the `UpdateKey` method call MinIO can ask the KMS to decrypt
`E(dk)` with the old key (internally) and re-encrypted `dk` with
the new master key value: `E'(dk)`.
However, this operation only works for the same master key ID.
When rotating the data key (replacing it with a new one) then
we perform a `UnsealKey` operation with the 1st master key ID
and then a `GenerateKey` operation with the 2nd master key ID.
This commit also updates the KMS documentation and removes
the `encrypt` policy entry (we don't use `encrypt`) and
add a policy entry for `rewarp`.
There is no reliable way to handle fallbacks for
MinIO deployments, due to various command line
options and multiple locations which require
access inside container.
Parsing command line options is tricky to figure
out which is the backend disk etc, we did try
to fix this in implementations of check-user.go
but it wasn't complete and introduced more bugs.
This PR simplifies the entire approach to rather
than running Docker container as non-root by default
always, it allows users to opt-in. Such that they
are aware that that is what they are planning to do.
In-fact there are other ways docker containers can
be run as regular users, without modifying our
internal behavior and adding more complexities.
- Snappy is not and RLE compressor, it is LZ77 based.
- Add `xz` as a common file type.
- Add most common media container types.
- Never heard of `application/x-spoon`. Google turns up a blank as well.
- Change link to minio blog post on compression & encryption.
This commit removes the encryption key section from
the certool.exe docs because:
- MinIO does not support any TLS cipher that encrypts
something with the private key. We only support PFS
ciphers.
- The doc comment is not really accurate anyway.
This PR adds support for adding session policies
for further restrictions on STS credentials, useful
in situations when applications want to generate
creds for multiple interested parties with different
set of policy restrictions.
This session policy is not mandatory, but optional.
Fixes#7732
etcd when used in federated setups, currently
mandates that all clusters should have same
config.json, which is too restrictive and makes
federation a restrictive environment.
This change makes it apparent that each cluster
needs to be independently managed if necessary
from `mc admin info` command line.
Each cluster with in federation can have their
own root credentials and as well as separate
regions. This way buckets get further restrictions
and allows for root creds to be not common
across clusters/data centers.
Existing data in etcd gets migrated to backend
on each clusters, upon start. Once done
users can change their config entries
independently.
This will allow cache to consistently work for
server and gateways. Range GET requests will
be cached in the background after the request
is served from the backend.
Fixes: #7458, #7573, #6265, #6630
- [x] Support bucket and regular object operations
- [x] Supports Select API on HDFS
- [x] Implement multipart API support
- [x] Completion of ListObjects support
- The events will be persisted in queueStore if `queueDir` is set.
- Else, if queueDir is not set events persist in memory.
The events are replayed back when the mqtt broker is back online.
This change adds support for casting strings to Timestamp via CAST:
`CAST('2010T' AS TIMESTAMP)`
It also implements the following date-time functions:
- UTCNOW()
- DATE_ADD()
- DATE_DIFF()
- EXTRACT()
For values passed to these functions, date-types are automatically
inferred.
More than one client can't use the same clientID for MQTT connection.
This causes problem in distributed deployments where config is shared
across nodes, as each Minio instance tries to connect to MQTT using the
same clientID.
This commit removes the clientID field in config, and allows
MQTT client to create random clientID for each node.
- New parser written from scratch, allows easier and complete parsing
of the full S3 Select SQL syntax. Parser definition is directly
provided by the AST defined for the SQL grammar.
- Bring support to parse and interpret SQL involving JSON path
expressions; evaluation of JSON path expressions will be
subsequently added.
- Bring automatic type inference and conversion for untyped
values (e.g. CSV data).
Requirements like being able to run minio gateway in ec2
pointing to a Minio deployment wouldn't work properly
because IAM creds take precendence on ec2.
Add checks such that we only enable AWS specific features
if our backend URL points to actual AWS S3 not S3 compatible
endpoints.
- Default support for S3 dualstack endpoints (IPv6 support)
- Support granular policy conditionals in List operations
- Support proxy cookies for stickiness
This commit adds some documentation about the design of the
SSE-C and SSE-S3 implementation. It describes how the Minio server
encrypt objects and manages keys.
This PR adds pass-through, single encryption at gateway and double
encryption support (gateway encryption with pass through of SSE
headers to backend).
If KMS is set up (either with Vault as KMS or using
MINIO_SSE_MASTER_KEY),gateway will automatically perform
single encryption. If MINIO_GATEWAY_SSE is set up in addition to
Vault KMS, double encryption is performed.When neither KMS nor
MINIO_GATEWAY_SSE is set, do a pass through to backend.
When double encryption is specified, MINIO_GATEWAY_SSE can be set to
"C" for SSE-C encryption at gateway and backend, "S3" for SSE-S3
encryption at gateway/backend or both to support more than one option.
Fixes#6323, #6696
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).
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
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 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
This PR adds support
- Request query params
- Request headers
- Response headers
AuditLogEntry is exported and versioned as well
starting with this PR.
This PR supports two models for etcd certs
- Client-to-server transport security with HTTPS
- Client-to-server authentication with HTTPS client certificates
