Make sure to skip reserved bucket names in `ListBuckets()`
current code didn't skip this properly and also generalize
this behavior for both XL and FS.
Also changes the behavior of `secretKeyHash` which is
not necessary to be sent over the network, each node
has its own secretKeyHash to validate.
Fixes#3696
Partial(fix) #3700 (More changes needed with some code cleanup)
Creds don't require secretKeyHash to be calculated
everytime, cache it instead and re-use.
This is an optimization for bcrypt.
Relevant results from the benchmark done locally, negative
value means improvement in this scenario.

* Rename GenericArgs to AuthRPCArgs
* Rename GenericReply to AuthRPCReply
* Remove authConfig.loginMethod and add authConfig.ServiceName
* Rename loginServer to AuthRPCServer
* Rename RPCLoginArgs to LoginRPCArgs
* Rename RPCLoginReply to LoginRPCReply
* Version and RequestTime are added to LoginRPCArgs and verified by
server side, not client side.
* Fix data race in lockMaintainence loop.
This change adds more richer error response
for JSON-RPC by interpreting object layer
errors to corresponding meaningful errors
for the web browser.
```go
&json2.Error{
Message: "Bucket Name Invalid, Only lowercase letters, full stops, and numbers are allowed.",
}
```
Additionally this patch also allows PresignedGetObject()
to take expiry parameter to have variable expiry.
- Adds an interface to update in-memory bucket metadata state called
BucketMetaState - this interface has functions to:
- update bucket notification configuration,
- bucket listener configuration,
- bucket policy configuration, and
- send bucket event
- This interface is implemented by `localBMS` a type for manipulating
local node in-memory bucket metadata, and by `remoteBMS` a type for
manipulating remote node in-memory bucket metadata.
- The remote node interface, makes an RPC call, but the local node
interface does not - it updates in-memory bucket state directly.
- Rename mkPeersFromEndpoints to makeS3Peers and refactored it.
- Use arrayslice instead of map in s3Peers struct
- `s3Peers.SendUpdate` now receives an arrayslice of peer indexes to
send the request to, with a special nil value slice indicating that
all peers should be sent the update.
- `s3Peers.SendUpdate` now returns an arrayslice of errors, representing
errors from peers when sending an update. The array positions
correspond to peer array s3Peers.peers
Improve globalS3Peers:
- Make isDistXL a global `globalIsDistXL` and remove from s3Peers
- Make globalS3Peers an array of (address, bucket-meta-state) pairs.
- Fix code and tests.
