With CoreDNS now supporting etcdv3 as the DNS backend, we
can update our federation target to etcdv3. Users will now be
able to use etcdv3 server as the federation backbone.
Minio will update bucket data to etcdv3 and CoreDNS can pick
that data up and serve it as bucket style DNS path.
This change updates the vendor'd x/crypto/blake2b package and
adds x/sys/cpu.
This change fixes an issue for Go1.11 affecting x/crypto/blake2b
since G1.11 removes the runtime-internal functions `suports_avx()` and
`supports_avx2()`.
This change adds some security headers like Content-Security-Policy.
It does not set the HSTS header because Content-Security-Policy prevents
mixed HTTP and HTTPS content and the server does not use cookies.
However it is a header which could be added later on.
It also moves some header added by #5805 from a vendored file
to a generic handler.
Fixes ##5813
Some HTTP security headers in Minio.
To avoid problems with XSS and Clickjacking attacks.
X-Frame-Options
X-Frame-Options response header improve the protection
of web applications against Clickjacking. It declares a
policy communicated from a host to the client browser
on whether the browser must not display the transmitted
content in frames of other web pages.
X-XSS-Protection
This header enables the Cross-site scripting (XSS) filter in your browser.
This PR adds disk based edge caching support for minio server.
Cache settings can be configured in config.json to take list of disk drives,
cache expiry in days and file patterns to exclude from cache or via environment
variables MINIO_CACHE_DRIVES, MINIO_CACHE_EXCLUDE and MINIO_CACHE_EXPIRY
Design assumes that Atime support is enabled and the list of cache drives is
fixed.
- Objects are cached on both GET and PUT/POST operations.
- Expiry is used as hint to evict older entries from cache, or if 80% of cache
capacity is filled.
- When object storage backend is down, GET, LIST and HEAD operations fetch
object seamlessly from cache.
Current Limitations
- Bucket policies are not cached, so anonymous operations are not supported in
offline mode.
- Objects are distributed using deterministic hashing among list of cache
drives specified.If one or more drives go offline, or cache drive
configuration is altered - performance could degrade to linear lookup.

Currently minio master requires 4 servers, we
have decided to run on a minimum of 2 servers
instead - fixes a regression from previous
releases where 3 server setups were supported.
In current implementation we used as many dsync clients
as per number of endpoints(along with path) which is not
the expected implementation. The implementation of Dsync
was expected to be just for the endpoint Host alone such
that if you have 4 servers and each with 4 disks we need
to only have 4 dsync clients and 4 dsync servers. But
we currently had 8 clients, servers which in-fact is
unexpected and should be avoided.
This PR brings the implementation back to its original
intention. This issue was found #5160
This change adds the HighwayHash256 PRF as bitrot protection / detection
algorithm. Since HighwayHash256 requires a 256 bit we generate a random
key from the first 100 decimals of π - See nothing-up-my-sleeve-numbers.
This key is fixed forever and tied to the HighwayHash256 bitrot algorithm.
Fixes#5358
Internally, triton-go, what manta minio is built on, changed it's internal
error handling. This means we no longer need to unwrap specific error types
This doesn't change any manta minio functionality - it just changes how errors are
handled internally and adds a wrapper for a 404 error
Manta has the ability to allow users to authenticate with a
username other than the main account. We want to expose
this functionality to minio manta gateway.
- Update startup banner to print storage class in capitals. This
makes it easier to identify different storage classes available.
- Update response metadata to not send STANDARD storage class.
This is in accordance with AWS S3 behaviour.
- Update minio-go library to bring in storage class related
changes. This is needed to make transparent translation of
storage class headers for Minio S3 Gateway.
Manta is an Object Storage by [Joyent](https://www.joyent.com/)
This PR adds initial support for Manta. It is intended as non-production
ready so that feedback can be obtained.
This PR allows 'minio update' to not only shows update banner
but also allows for in-place upgrades.
Updates are done safely by validating the downloaded
sha256 of the binary.
Fixes#4781
- Adds a metadata argument to the CopyObjectPart API to facilitate
implementing encryption for copying APIs too.
- Update vendored minio-go - this version implements the
CopyObjectPart client API for use with the S3 gateway.
Fixes#4885
This change adds server-side-encryption support for HEAD, GET and PUT
operations. This PR only addresses single-part PUTs and GETs without
HTTP ranges.
Further this change adds the concept of reserved object metadata which is required
to make encrypted objects tamper-proof and provide API compatibility to AWS S3.
This PR adds the following reserved metadata entries:
- X-Minio-Internal-Server-Side-Encryption-Iv ('guarantees' tamper-proof property)
- X-Minio-Internal-Server-Side-Encryption-Kdf (makes Key-MAC computation negotiable in future)
- X-Minio-Internal-Server-Side-Encryption-Key-Mac (provides AWS S3 API compatibility)
The prefix `X-Minio_Internal` specifies an internal metadata entry which must not
send to clients. All client requests containing a metadata key starting with `X-Minio-Internal`
must also rejected. This is implemented by a generic-handler.
This PR implements SSE-C separated from client-side-encryption (CSE). This cannot decrypt
server-side-encrypted objects on the client-side. However, clients can encrypted the same object
with CSE and SSE-C.
This PR does not address:
- SSE-C Copy and Copy part
- SSE-C GET with HTTP ranges
- SSE-C multipart PUT
- SSE-C Gateway
Each point must be addressed in a separate PR.
Added to vendor dir:

This PR addresses a long standing dependency on
`gopkg.in/check.v1` project used for our tests.
All tests are re-written to use the go default
testing framework instead.
There was no reason for us to use an external
package where Go tools are sufficient for this.
The reedsolomon library now avoids allocations during reconstruction.
This change exploits that to reduce memory allocs and GC preasure during
healing and reading.
- Region handling can now use region endpoints directly.
- All uploads are streaming no more large buffer needed.
- Major API overhaul for CopyObject(dst, src)
- Fixes bugs present in existing code for copying
- metadata replace directive CopyObject
- PutObjectPart doesn't require md5Sum and sha256
NOTE: This doesn't validate that minio will work fine
on these platforms and is tested. Since we do not validate
on these architectures this is to be treated as just a build fix.
Fixes#4858
Bcrypt is not neccessary and not used properly. This change
replace the whole bcrypt hash computation through a constant time
compare and removes bcrypt from the code base.
This change provides new implementations of the XL backend operations:
- create file
- read file
- heal file
Further this change adds table based tests for all three operations.
This affects also the bitrot algorithm integration. Algorithms are now
integrated in an idiomatic way (like crypto.Hash).
Fixes#4696Fixes#4649Fixes#4359
* Prevent unnecessary verification of parity blocks while reading erasure
coded file.
* Update klauspost/reedsolomon and just only reconstruct data blocks while
reading (prevent unnecessary parity block reconstruction)
* Remove Verification of (all) reconstructed Data and Parity blocks since
in our case we are protected by bit rot protection. And even if the
verification would fail (essentially impossible) there is no way to
definitively say whether the data is still correct or not, so this call
make no sense for our use case.
