delete marked objects should not be considered
for listing when listing is delimited, this issue
as introduced in PR #13804 which was mainly to
address listing of directories in listing when
delimited.
This PR fixes this properly and adds tests to
ensure that we behave in accordance with how
an S3 API behaves for ListObjects() without

Return errors when untar fails at once.
Current error handling was quite a mess. Errors are written
to the stream, but processing continues.
Instead, return errors when they occur and transform
internal errors to bad request errors, since it is likely a
problem with the input.

Sometimes, we see an error message like "Server expects 'storage' API

The earlier approach of using a license token for
communicating with SUBNET is being replaced
with a simpler mechanism of API keys. Unlike the
license which is a JWT token, these API keys will
be simple UUID tokens and don't have any embedded
information in them. SUBNET would generate the
API key on cluster registration, and then it would
be saved in this config, to be used for subsequent
communication with SUBNET.
Following scenario such as objects that exist inside a
prefix say `folder/` must be included in the listObjects()
response.
```
2aa16073-387e-492c-9d59-b4b0b7b6997a v2 DEL folder/
a5b9ce68-7239-4921-90ab-20aed402c7a2 v1 PUT folder/
f2211798-0eeb-4d9e-9184-fcfeae27d069 v1 PUT folder/1.txt
```
Current master does not handle this scenario, because it
ignores the top level delete-marker on folders. This is
however unexpected. It is expected that list-objects returns
the top level prefix in this situation.
```
aws s3api list-objects --bucket harshavardhana --prefix unique/ \
--delimiter / --profile minio --endpoint-url http://localhost:9000
{
"CommonPrefixes": [
{
"Prefix": "unique/folder/"
}
]
}
```
There are applications in the wild such as Hadoop s3a connector
that exploit this behavior and expect the folder to be present
in the response.
This also makes the behavior consistent with AWS S3.

Update tests as well to handle the proper requirement. All
these changes are needed when migrating from older deployments
where we used to set N/2 quorum for reads to EC:4 parity in
newer releases.
dataDir loosely based on maxima is incorrect and does not
work in all situations such as disks in the following order
- xl.json migration to xl.meta there may be partial xl.json's
leftover if some disks are not yet connected when the disk
is yet to come up, since xl.json mtime and xl.meta is
same the dataDir maxima doesn't work properly leading to
quorum issues.
- its also possible that XLV1 might be true among the disks
available, make sure to keep FileInfo based on common quorum
and skip unexpected disks with the older data format.
Also, this PR tests upgrade from older to a newer release if the
data is readable and matches the checksum.
NOTE: this is just initial work we can build on top of this to do further tests.
there is a corner case where the new check
doesn't work where dataDir has changed, especially
when xl.json -> xl.meta healing happens, if some
healing is partial this can make certain backend
files unreadable.
This PR fixes and updates unit-tests

currently getReplicationConfig() failure incorrectly
returns error on unexpected buckets upon upgrade, we
should always calculate usage as much as possible.
listing can fail and it is allowed to be retried,
instead of returning right away return an error at
the end - heal the rest of the buckets and objects,
and when we are retrying skip the buckets that
are already marked done by using the tracked buckets.

This allows quickly parsing everything as slices of bytes (no copy).
Versions are always *saved* sorted by modTime, newest *first*.

* Allows adding/updating/deleting a version with only header deserialization.
* Reduces allocations on conversion to FileInfo(s).

default-populated during unmarshalling of the JSON.

This commit makes the MinIO server behavior more consistent
w.r.t. key usage verification.
When MinIO verifies the client certificates it also checks
that the client certificate is valid of client authentication
(or any (i.e. wildcard) usage).
However, the MinIO server used to not verify the client key usage
when client certificate verification was disabled.
Now, the MinIO server verifies the client key usage even when
client certificate verification has been disabled. This makes
the MinIO behavior more consistent from a client's perspective.
Now, a client certificate has to be valid for client authentication
in all cases.

Borrowed idea from Go's usage of this
optimization for ReadFrom() on client

io.Copy() allocates for generic copy
from a reader to writer.

- Ensure all actions accessing storage lock properly.
- Behavior change: policies can be deleted only when they
are not associated with any active credentials.
- The race happens with a goroutine that refreshes IAM cache data from storage.
- It could lead to deleted users re-appearing as valid live credentials.
- This change also causes CI to run tests without a race flag (in addition to
running it with).
deleting collection of versions belonging
to same object, we can avoid re-reading
the xl.meta from the disk instead purge
all the requested versions in-memory,
the tradeoff is to allocate a map to de-dup
the versions, allow disks to be read only
once per object.
additionally reduce the data transfer between
nodes by shortening msgp data values.
- combine similar looking functionalities into single
handlers, and remove unnecessary proxying of the
requests at handler layer.
- remove bucket forwarding handler as part of default setup
add it only if bucket federation is enabled.

Removes RLock/RUnlock for updating metadata,
since we already take a write lock to update
metadata, this change removes reading of xl.meta
as well as an additional lock, the performance gain
should increase 3x theoretically for
- PutObjectRetention
- PutObjectLegalHold
This optimization is mainly for Veeam like
workloads that require a certain level of iops
from these API calls, we were losing iops.
read/writers are not concurrent in handlers
and self contained - no need to use atomics on
them.
avoids unnecessary contentions where it's not
required.
Logger targets were not race protected against concurrent updates from for example `HTTPConsoleLoggerSys`.
Restrict direct access to targets and make slices immutable so a returned slice can be processed safely without locks.
As we use etcd's watch interface, we do not need the
network notifications as they are no-ops anyway.
Bonus: Remove globalEtcdClient global usage in IAM
IAMSys is a higher-level object, that should not be called by the lower-level
storage API interface for IAM. This is to prepare for further improvements in
IAM code.
etcd operations, get/put/delete, should be logged when failed
with errors other than not found error. It will make it easier to
see connections issues from MinIO to etcd.

Looks like policy restriction was not working properly
for normal users when they are not svc or STS accounts.
- svc accounts are now properly fixed to get
right permissions when its inherited, so
we do not have to set 'owner = true'
- sts accounts have always been using right
permissions, do not need an explicit lookup
- regular users always have proper policy mapping
- avoids relying in listQuorum from the underlying listObjects()
and potentially missing entries if any.
- avoid the entire merging logic etc, listing raw set by set
and loading whatever is found is cleaner when dealing with
a large cluster for IAM metadata.

This was a regression introduced in '14bb969782'
this has the potential to cause corruption when
there are concurrent overwrites attempting to update
the content on the namespace.
This PR adds a situation where PutObject(), CopyObject()
compete properly for the same locks with NewMultipartUpload()
however it ends up turning off competing locks for the actual
object with GetObject() and DeleteObject() - since they do not
compete due to concurrent I/O on a versioned bucket it can lead
to loss of versions.
This PR fixes this bug with multi-pool setup with replication
that causes corruption of inlined data due to lack of competing
locks in a multi-pool setup.
Instead CompleteMultipartUpload holds the necessary
locks when finishing the transaction, knowing the exact
location of an object to schedule the multipart upload
doesn't need to compete in this manner, a pool id location
for existing object.
This reverts commit 91567ba916.
Revert because the error was incorrectly converted, there are
callers that rely on errConfigNotFound and it also took away
the migration code.
Instead the correct fix is PutBucketTaggingHandler() which
is already added.
also remove HealObjects() code from dataScanner running another
listing from the data-scanner is super in-efficient and in-fact
this code is redundant since we already attempt to heal all
dangling objects anyways.
- Supports object locked buckets that require
PutObject() to set content-md5 always.
- Use SSE-S3 when S3 gateway is being used instead

- globalNotificationSys
- globalTargetSys
converge them directly into single bucket metadata sys
loader, once that is loaded automatically every other
target should be loaded and configured properly.

DeleteObject() on existing objects before `xl.json` to
`xl.meta` change were not working, not sure when this
regression was added. This PR fixes this properly.
Also this PR ensures that we perform rename of xl.json
to xl.meta only during "write" phase of the call i.e
either during Healing or PutObject() overwrites.
Also handles few other scenarios during migration where
`backendEncryptedFile` was missing deleteConfig() will
fail with `configNotFound` this case was not ignored,
which can lead to failure during upgrades.
once we have competed for locks, verify if the
context is still valid - this is to ensure that
we do not start readdir() or read() calls on the
drives on canceled connections.
This commit brings two locks instead of single lock for
WalkDir() calls on top of c25816eabc.
The main reason is to avoid contention between readMetadata()
and ListDir() calls, ListDir() can take time on prefixes that
are huge for readdir() but this shouldn't end up blocking
all readMetadata() operations, this allows for more room for
I/O while not overly penalizing all listing operations.
This commit fixes an issue in the `AssumeRoleWithCertificate`
handler.
Before clients received an error when they send
a chain of X.509 certificates (their client certificate as

Now, client can send a certificate chain and the server
will only consider non-CA / leaf certificates as possible
client certificate candidates. However, the client still
can only send one certificate.

This commit adds a new STS API for X.509 certificate

The problem is that it will begin writing to the response before the
body is read after 10 seconds. This will abort the writes on the
client-side, since it assumes the server has received what it wants.
The proposed solution here is to monitor the completion of the body
before beginning to send keepalive pings.
Fixes observed high number of goroutines stuck in `io.Copy` in
`github.com/minio/minio/cmd.(*xlStorage).CreateFile` and
`(*storageRESTClient).CreateFile` stuck in `http.DrainBody`.
In the event when a lock is not refreshed in the cluster, this latter
will be automatically removed in the subsequent cleanup of non
refreshed locks routine, but it forgot to clean the local server,
hence having the same weird stale locks present.
This commit will remove the lock locally also in remote nodes, if
removing a lock from a remote node will fail, it will be anyway
removed later in the locks cleanup routine.
Currently in master this can cause existing
parent users to stop working and lead to
credentials getting overwritten.
```
~ mc admin user add alias/ minio123 minio123456
```
```
~ mc admin user svcacct add alias/ minio123 \
--access-key minio123 --secret-key minio123456
```
This PR rejects all such scenarios.
Faster healing as well as making healing more
responsive for faster scanner times.
also fixes a bug introduced in #13079, newly replaced
disks were not healing automatically.
- remove sourceCh usage from healing
we already have tasks and resp channel
- use read locks to lookup globalHealConfig
- fix healing resolver to pick candidates quickly
that need healing, without this resolver was
unexpectedly skipping.
healObject() should be non-blocking to ensure
that scanner is not blocked for a long time,
this adversely affects performance of the scanner
and also affects the way usage is updated
subsequently.
This PR allows for a non-blocking behavior for
healing, dropping operations that cannot be queued
anymore.
Synchronize bucket cycles so it is much more
likely that the same prefixes will be picked up
for scanning.
Use the global bloom filter cycle for that.
Bump bloom filter versions to clear those.
The intention is to list values of sys config that can potentially
impact the performance of minio.
At present, it will return max value configured for rlimit

proceed to heal the cluster when all the
drives in a set have failed, this is extremely
rare occurrence but even if it happens we allow
the cluster to be functional.
A recent regression caused new disks not being re-formatted. In the old
code, a disk needed be 'online' to be chosen to be formatted but the
disk has to be already formatted for XL storage IsOnline() function to
return true.
It is enough to check if XL storage is nil or not if we want to avoid
formatting root disks.

markRootDisksAsDown() relies on disk info even if the
disk is unformatted. Therefore, we should always return
DiskInfo data even when DiskInfo storage API returns
errUnformattedDisk
`mc admin heal` command will show servers/disks tolerance, for that
purpose, you need to know the number of parity disks for each storage
class.
Parity is always the same in all pools.
prefixes at top level create such as
```
~ mc mb alias/bucket/prefix
```
The prefix/ incorrect appears as prefix__XL_DIR__/
in the accountInfo output, make sure to trim '__XL_DIR__'
Objects uploaded in this format for example
```
mc cp /etc/hosts alias/bucket/foo/bar/xl.meta
mc ls -r alias/bucket/foo/bar
```
Won't list the object, handle this scenario.
Ensure that one call will succeed and others will serialize
Example failure without code in place:
```
bucket-policy-handlers_test.go:120: unexpected error: cmd.InsufficientWriteQuorum: Storage resources are insufficient for the write operation doz2wjqaovp5kvlrv11fyacowgcvoziszmkmzzz9nk9au946qwhci4zkane5-1/

bucket-policy-handlers_test.go:135: want 1 ok, got 0
```
We are observing heavy system loads, potentially
locking the system up for periods when concurrent
listing operations are performed.
We place a per-disk lock on walk IO operations.
This will minimize the impact of concurrent listing
operations on the entire system and de-prioritize
them compared to other operations.
Single list operations should remain largely unaffected.
Some applications albeit poorly written rather than using headObject
rely on listObjects to check for existence of object, this unusual
request always has prefix=(to actual object) and max-keys=1
handle this situation specially such that we can avoid readdir()
on the top level parent to avoid sorting and skipping, ensuring
that such type of listObjects() always behaves similar to a
headObject() call.
this addresses a regression from #12984
which only addresses flat key from single
level deep at bucket level.
added extra tests as well to cover all
these scenarios.
- deletes should always Sweep() for tiering at the
end and does not need an extra getObjectInfo() call
- puts, copy and multipart writes should conditionally
do getObjectInfo() when tiering targets are configured
- introduce 'TransitionedObject' struct for ease of usage
and understanding.
- multiple-pools optimization deletes don't need to hold
read locks verifying objects across namespace and pools.
baseDir is empty if the top level prefix does not
end with `/` this causes large recursive listings
without any filtering, to fix this filtering make
sure to set the filter prefix appropriately.
also do not navigate folders at top level that do
not match the filter prefix, entries don't need
to match prefix since they are never prefixed
with the prefix anyways.
The previous code removes SVC/STS accounts for ldap users that do not
exist anymore in LDAP server. This commit will actually re-evaluate
filter as well if it is changed and remove all local SVC/STS accounts
beloning to the ldap user if the latter is not eligible for the
search filter anymore.
For example: the filter selects enabled users among other criteras in
the LDAP database, if one ldap user changes his status to disabled
later, then associated SVC/STS accounts will be removed because that user
does not meet the filter search anymore.
Traffic metering was not protected against concurrent updates.

This happens because of a change added where any sub-credential
with parentUser == rootCredential i.e (MINIO_ROOT_USER) will
always be an owner, you cannot generate credentials with lower
session policy to restrict their access.
This doesn't affect user service accounts created with regular
users, LDAP or OpenID
Use `readMetadata` when reading version
information without data requested.
Reduces IO on inlined data.
Bonus: Inline compressed data as well when
compression is enabled.
