The current code for deleting 1000 objects simultaneously
causes significant random I/O, which on slower drives
leads to servers disconnecting in a distributed setup.
Simplify this by serially deleting and reducing the
chattiness of this operation.
Currently, requestid field in logEntry is not populated, as the
requestid field gets set at the very end.
It is now set before regular handler functions. This is also
useful in setting it as part of the XML error response.
Travis build for ppc64le has been quite inconsistent and stays queued
for most of the time. Removing this build as part of Travis.yml for
the time being.
- Add console target logging, enabled by default.
- Add http target logging, which supports an endpoint
with basic authentication (username/password are passed
in the endpoint url itself)
- HTTP target logging is asynchronous and some logs can be
dropped if channel buffer (10000) is full
In a small window, UI error tries to split lines for an eye candy
error message. However, since we show some docs.minio.io links in some
error messages, these links are actually broken and not easily selected
in a X terminal. This PR changes the behavior and won't split lines
anymore.
This commit adds basic support for SSE-C / SSE-C copy.
This includes functions for determining whether SSE-C
is requested by the S3 client and functions for parsing
such HTTP headers.
All S3 SSE-C parsing errors are exported such that callers
can pattern-match to forward the correct error to S3
clients.
Further the SSE-C related internal metadata entry-keys
are added by this commit.
This commit adds a basic KMS implementation for an
operator-specified SSE-S3 master key. The master key
is wrapped as KMS such that using SSE-S3 with master key
and SSE-S3 with KMS can use the same code.
Bindings for a remote / true KMS (like hashicorp vault)
will be added later on.
This commit updates the key derivation to reflect the
latest change of crypto/doc.go. This includes handling
the insecure legacy KDF.
Since #6064 is fixed, the 3. test case for object key
generation is enabled again.
Order for server:disk originally provided wouldn't stripe
wide and may lead to availability issues.
Also added Short-form examples using {1...n} and a
warning about {1..2} vs {1...3}
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 commit fixes the size calculation for multipart
objects. The decrypted size of an encrypted multipart
object is the sum of the decrypted part sizes.
Also fixes the key derivation in CopyObjectPart.
Instead of using the same object-encryption-key for each
part now an unique per-part key is derived.
Updates #6139
Minio server was preventing itself to start when any notification
target is down and not running. The PR changes the behavior by
avoiding startup abort in that case, so the user will still
be able to access Minio server using mc admin commands after
a restart or set config commands.
This commit fixes a weakness of the key-encryption-key
derivation for SSE-C encrypted objects. Before this
change the key-encryption-key was not bound to / didn't
depend on the object path. This allows an attacker to
repalce objects - encrypted with the same
client-key - with each other.
This change fixes this issue by updating the
key-encryption-key derivation to include:
- the domain (in this case SSE-C)
- a canonical object path representation
- the encryption & key derivation algorithm
Changing the object path now causes the KDF to derive a
different key-encryption-key such that the object-key
unsealing fails.
Including the domain (SSE-C) and encryption & key
derivation algorithm is not directly neccessary for this
fix. However, both will be included for the SSE-S3 KDF.
So they are included here to avoid updating the KDF
again when we add SSE-S3.
The leagcy KDF 'DARE-SHA256' is only used for existing
objects and never for new objects / key rotation.
Commit 0d52126023 caused a regression in setting
a new bucket policy in a distributed setup. The reason is that gob is not able
to encode fields declared as interfaces unless we provide GobEncode() and GobDecode()
This PR adds them by using json marshaller and unmarshaller that are already
implemented for Functions interface.
Certain SCSI drivers do not allow certain tuning parameters
like nr_requests, max_sectors_kb to be changed, ignore these
errors silently as this script is simply a best effort.
Fixes#6103
