A. Elleuch 2244adff07 fix: Better printing of XL config init error (#5284) 2017-12-28 23:02:48 +05:30
Harshavardhana 1d8a8c63db Simplify data verification with HashReader. (#5071)
Verify() was being called by caller after the data
has been successfully read after io.EOF. This disconnection
opens a race under concurrent access to such an object.
Verification is not necessary outside of Read() call,
we can simply just do checksum verification right inside
Read() call at io.EOF.

This approach simplifies the usage.

Harshavardhana d3eb5815d9 Avoid DDOS in PutObject() when objectName is '/' and size '0' (#4962)
It can happen that an incoming PutObject() request might
have inputs of following form eg:-

 - bucketName is 'testbucket'
 - objectName is '/'

bucketName exists and was previously created but there
are no other objects in this bucket. In a situation like
this parentDirIsObject() goes into an infinite loop.

Verifying that if '/' is an object fails on both backends
but the resulting `path.Dir('/')` returns `'/'` this causes
the closure to loop onto itself.

Fixes #4940
