If it does happen that we have a lot files in '.minio.sys/tmp',
minio startup might block deleting this folder. Rename and
delete in background instead to allow Minio to start serving
requests.
To avoid a large number of concurrent connections between minio
servers and to reduce CPU pressure, it is better to limit the number
of objects healed in parallel to number_of_CPUs.
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.
Returning unexpected errors can cause problems for config handling,
which is what led gateway deployments with etcd to misbehave and
had stopped working properly
Deployment ID is not copied into new formats after healing format. Although,
this is not critical since a new deployment ID will be generated and set in the
next cluster restart, it is still much better if we don't change the deployment
id of a cluster for a better tracking.
Fix regexp matcher for special assets for the browser to clash with
less of the object namespace.
Assets should now be loaded with the /minio/ prefix. Previously,
favicon.ico (and others) could be loaded at any path matching
/minio/*/favicon.ico. This clashes with a large part of the object
namespace. With this change, /minio/favicon.ico will serve the favicon
but not /minio/mybucket/favicon.ico
Fixes#7077
This changes causes `getRootCAs` to always load system-wide CAs.
Any additional custom CAs (at `certs/CA/`) are added to the certificate pool
of system CAs.
The previous behavior was incorrect since all no system-wide CAs were
loaded if either there were CAs under `certs/CA` or the `certs/CA`
directory didn't exist at all.
Also add a cross compile script to test always cross
compilation for some well known platforms and architectures
, we support out of box compilation of these platforms even
if we don't make an official release build.
This script is to avoid regressions in this area when we
add platform dependent code.
This PR supports iam and bucket policies to have
policy variable replacements in resource and
condition key values.
For example
- ${aws:username}
- ${aws:userid}
Health checking programs very frequently use /minio/health/live
to check health, hence we can avoid doing StorageInfo() and
ListBuckets() for FS/Erasure backend.
* Use 0-byte file for bitrot verification of whole-file-bitrot files
Also pass the right checksum information for bitrot verification
* Copy xlMeta info from latest meta except []checksums and []Parts while healing
Simplify parallelReader.Read() which also fixes previous
implementation where it was returning before all the parallel
reading go-routines had terminated which caused race conditions.
When auto-encryption is turned on, we pro-actively add SSEHeader
for all PUT, POST operations. This is unusual for V2 signature
calculation because V2 signature doesn't have a pre-defined set
of signed headers in the request like V4 signature. According to
V2 we should canonicalize all incoming supported HTTP headers.
Make sure to validate signatures before we mutate http headers
Deprecate the use of Admin Peers concept and migrate all peer
communication to Notification subsystem. This finally allows
for a common subsystem for all peer notification in case of
distributed server deployments.
Before this change the CopyObjectHandler and the CopyObjectPartHandler
both looked for a `versionId` parameter on the `X-Amz-Copy-Source` URL
for the version of the object to be copied on the URL unescaped version
of the header. This meant that files that had question marks in were
truncated after the question mark so that files with `?` in their
names could not be server side copied.
After this change the URL unescaping is done during the parsing of the
`versionId` parameter which fixes the problem.
This change also introduces the same logic for the
`X-Amz-Copy-Source-Version-Id` header field which was previously
ignored, namely returning an error if it is present and not `null`
since minio does not currently support versions.

When source is encrypted multipart object and the parts are not
evenly divisible by DARE package block size, target encrypted size
will not necessarily be the same as encrypted source object.
This commit removes old code preventing PUT requests with '/' as a path,
because this is not needed anymore after the introduction of the virtual
host style in Minio server code.
'PUT /' when global domain is not configured already returns 405 Method
Not Allowed http error.
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 is part of implementation for mc admin health command. The
ServerDrivesPerfInfo() admin API returns read and write speed
information for all the drives (local and remote) in a given Minio
server deployment.
Part of minio/mc#2606
It can happen with erroneous clients which do not send `Host:`
header until 4k worth of header bytes have been read. This can lead
to Peek() method of bufio to fail with ErrBufferFull.
To avoid this we should make sure that Peek buffer is as large as
our maxHeaderBytes count.
