Hot load a policy document when during account authorization evaluation
to avoid returning 403 during server startup, when not all policies are
already loaded.
Add this support for group policies as well.
you can attempt a rebalance first i.e, start with 2 pools.
```
mc admin rebalance start alias/
```
and after that you can add a new pool, this would
potentially crash.

specifying customer HTTP client makes the gcs SDK

SDK manage the transport.
this PR fixes#19922 a regression from #19565
Currently, bucket metadata is being loaded serially inside ListBuckets
Objet API. Fix that by loading the bucket metadata as the number of
erasure sets * 10, which is a good approximation.
since the connection is active, the
response recorder body can grow endlessly
causing leak, as this bytes buffer is
never given back to GC due to an goroutine.
skip healing properly in scanner when drive is hotplugged
due to how the state is passed around the SkipHealing
might not be the true state() of the system always, causing
a situation where we might healing from the scanner on the
same drive which is being. Due to this competing heals get
triggered that slow each other down.
due to a historic bug in CopyObject() where
an inlined object loses its metadata, the
check causes an incorrect fallback verifying
data-dir.
CopyObject() bug was fixed in ffa91f9794 however
the occurrence of this problem is historic, so
the aforementioned check is stretching too much.
Bonus: simplify fileInfoRaw() to read xl.json as well,
also recreate buckets properly.
* Multipart SSEC checksums were not transferred.
* Remove key mismatch logging. This key is user-controlled with SSEC.
* If the source is SSEC and the destination reports ErrSSEEncryptedObject,
assume replication is good.
avoid concurrent callers for LoadUser() to even initiate
object read() requests, if an on-going operation is in progress.
this avoids many callers hitting the drives causing I/O
spikes, also allows for loading credentials faster.
the reason for this is to avoid STS mappings to be
purged without a successful load of other policies,
and all the credentials only loaded successfully
are properly handled.
This also avoids unnecessary cache store which was
implemented earlier for optimization.
Directory objects are used by applications that simulate the folder
structure of an on-disk filesystem. These are zero-byte objects with names
ending with '/'. They are only used to check whether a 'folder' exists in
the namespace.
StartSize starts with the raw free space of all disks in the given pool,
however during the status, CurrentSize is not showing the current free
raw space, as expected at least by `mc admin decom status` since it was
written.
Go's net/http is notoriously difficult to have a streaming
deadlines per READ/WRITE on the net.Conn if we add them they
interfere with the Go's internal requirements for a HTTP
connection.
Remove this support for now
fixes#19853
In the very rare case when all drives in a erasure set need to be healed,
remove .healing.bin from all drives, otherwise it will be stuck in a
loop
Also, fix a unit test that fails sometimes due to wrong test.
since #19688 there was a regression introduced during drive
lookups for single node multi-drive setups, drive replacement
would not work correctly without this PR.
This does not fix any current issue, but merging https://github.com/minio/madmin-go/pull/282
can lose the validation of the service account expiration time.
Add more defensive code for now. In the future, we should avoid doing
validation in another library.
precondition check was being honored before, validating
if anonymous access is allowed on the metadata of an
object, leading to metadata disclosure of the following
headers.

although the information presented is minimal in nature,
and of opaque nature. It still simply discloses that an
object by a specific name exists or not without even having
enough permissions.
fix: authenticate LDAP via actual DN instead of normalized DN
Normalized DN is only for internal representation, not for
external communication, any communication to LDAP must be
based on actual user DN. LDAP servers do not understand
normalized DN.
fixes#19757
This change uses the updated ldap library in minio/pkg (bumped
up to v3). A new config parameter is added for LDAP configuration to
specify extra user attributes to load from the LDAP server and to store
them as additional claims for the user.
A test is added in sts_handlers.go that shows how to access the LDAP
attributes as a claim.
This is in preparation for adding SSH pubkey authentication to MinIO's SFTP
integration.
This commit will fix one rare case of a multipart object that
can be read in theory but GetObject API returned an error.
It turned out that a six years old code was marking a drive offline
when the bitrot streaming fails to read a part in a disk with any error.
This can affect reading a subsequent part, though having enough shards,
but unable to construct because one drive was marked offline earlier.
This commit will remove the drive marking offline code. It will also
close the bitrotstreaming reader before marking it as nil.
Currently, on enabling callhome (or restarting the server), the callhome
job gets scheduled. This means that one has to wait for 24hrs (the
default frequency duration) to see it in action and to figure out if it
is working as expected.
It will be a better user experience to perform the first callhome
execution immediately after enabling it (or on server start if already
enabled).
Also, generate audit event on callhome execution, setting the error
field in case the execution has failed.
* Store ModTime in the upload ID; return it when listing instead of the current time.
* Use this ModTime to expire and skip reading the file info.
* Consistent upload sorting in listing (since it now has the ModTime).
* Exclude healing disks to avoid returning an empty list.
