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.

as that is the only API where the TTFB metric is beneficial, and
capturing this for all APIs exponentially increases the response size in
large clusters.
Replace the `io.Pipe` from streamingBitrotWriter -> CreateFile with a fixed size ring buffer.
This will add an output buffer for encoded shards to be written to disk - potentially via RPC.
This will remove blocking when `(*streamingBitrotWriter).Write` is called, and it writes hashes and data.
With current settings, the write looks like this:
```
Outbound
┌───────────────────┐ ┌────────────────┐ ┌───────────────┐ ┌────────────────┐
│ │ Parr. │ │ (http body) │ │ │ │
│ Bitrot Hash │ Write │ Pipe │ Read │ HTTP buffer │ Write (syscall) │ TCP Buffer │
│ Erasure Shard │ ──────────► │ (unbuffered) │ ────────────► │ (64K Max) │ ───────────────────► │ (4MB) │
│ │ │ │ │ (io.Copy) │ │ │
└───────────────────┘ └────────────────┘ └───────────────┘ └────────────────┘
```
We write a Hash (32 bytes). Since the pipe is unbuffered, it will block until the 32 bytes have
been delivered to the TCP buffer, and the next Read hits the Pipe.
Then we write the shard data. This will typically be bigger than 64KB, so it will block until two blocks
have been read from the pipe.
When we insert a ring buffer:
```
Outbound
┌───────────────────┐ ┌────────────────┐ ┌───────────────┐ ┌────────────────┐
│ │ │ │ (http body) │ │ │ │
│ Bitrot Hash │ Write │ Ring Buffer │ Read │ HTTP buffer │ Write (syscall) │ TCP Buffer │
│ Erasure Shard │ ──────────► │ (2MB) │ ────────────► │ (64K Max) │ ───────────────────► │ (4MB) │
│ │ │ │ │ (io.Copy) │ │ │
└───────────────────┘ └────────────────┘ └───────────────┘ └────────────────┘
```
The hash+shard will fit within the ring buffer, so writes will not block - but will complete after a
memcopy. Reads can fill the 64KB buffer if there is data for it.
If the network is congested, the ring buffer will become filled, and all syscalls will be on full buffers.
Only when the ring buffer is filled will erasure coding start blocking.
Since there is always "space" to write output data, we remove the parallel writing since we are
always writing to memory now, and the goroutine synchronization overhead probably not worth taking.
If the output were blocked in the existing, we would still wait for it to unblock in parallel write, so it would
make no difference there - except now the ring buffer smoothes out the load.
There are some micro-optimizations we could look at later. The biggest is that, in most cases,
we could encode directly to the ring buffer - if we are not at a boundary. Also, "force filling" the
Read requests (i.e., blocking until a full read can be completed) could be investigated and maybe
allow concurrent memory on read and write.
Metrics being added:
- read_tolerance: No of drive failures that can be tolerated without
disrupting read operations
- write_tolerance: No of drive failures that can be tolerated without
disrupting write operations
- read_health: Health of the erasure set in a pool for read operations
(1=healthy, 0=unhealthy)
- write_health: Health of the erasure set in a pool for write operations
(1=healthy, 0=unhealthy)
Adds regression test for #19699
Failures are a bit luck based, since it requires objects to be placed on different sets.
However this generates a failure prior to #19699
* Revert "Revert "Fix incorrect merging of slash-suffixed objects (#19699)""
This reverts commit f30417d9a8.
* Don't override when suffix doesn't match. Instead rely on quorum for each.
Instead of having "online" and "healing" as two metrics, replace with a
single metric "health" which can have following values:
0 = offline
1 = healthy
2 = healing
If two objects share everything but one object has a slash prefix, those would be merged in listings,
with secondary properties used for a tiebreak.
Example: An object with the key `prefix/obj` would be merged with an object named `prefix/obj/`.
While this violates the [no object can be a prefix of another](https://min.io/docs/minio/linux/operations/concepts/thresholds.html#conflicting-objects), let's resolve these.
If we have an object with 'name' and a directory named 'name/' discard the directory only - but allow objects
of 'name' and 'name/' (xldir) to be uniquely returned.

This commit adds support for MinKMS. Now, there are three KMS
implementations in `internal/kms`: Builtin, MinIO KES and MinIO KMS.
Adding another KMS integration required some cleanup. In particular:
- Various KMS APIs that haven't been and are not used have been
removed. A lot of the code was broken anyway.
- Metrics are now monitored by the `kms.KMS` itself. For basic
metrics this is simpler than collecting metrics for external
servers. In particular, each KES server returns its own metrics
and no cluster-level view.
- The builtin KMS now uses the same en/decryption implemented by
MinKMS and KES. It still supports decryption of the previous
ciphertext format. It's backwards compatible.
- Data encryption keys now include a master key version since MinKMS
supports multiple versions (~4 billion in total and 10000 concurrent)
per key name.

ILM actions due to ExpiredObjectDeleteAllVersions and
DelMarkerExpiration are ignored when object locking is enabled on a
bucket.
Note: This applies to object versions which may not have retention
configured on them. This applies to all object versions in this bucket,
including those created before the retention config was applied.
Per-bucket metrics endpoints always start with /bucket and the bucket
name is appended to the path. e.g. if the collector path is /bucket/api,
the endpoint for the bucket "mybucket" would be

Bonus: Add a simple tool that echoes audit logs to the console.
When listing, with drives returning `errFileNotFound,` `errVolumeNotFound`, or `errUnformattedDisk,`,
we could get below `minDisks` drives being left.
This would result in a quorum never being reachable for any object. Therefore, the listing
would continue, but no results would ever be produced.
Include `fnf` in the mindisk check since it is incremented on these errors. This will stop
listing when minDisks are left.
Allow `opts.minDisks` to not return errVolumeNotFound or errFileNotFound and return that.
That will allow for good results even if disks return something else.
We switch `errUnformattedDisk` to a regular error. If we have enough of those, we should just fail.
Typically not all drives are connected, so we delay 3 minutes before resuming.
This greatly reduces risk of starting to list unconnected drives, or drives we risk being disconnected soon.
This delay is not applied when starting with an admin call.
ConsoleUI like applications rely on combination of
ListServiceAccounts() and InfoServiceAccount() to populate
UI elements, however individually these calls can be slow
causing the entire UI to load sluggishly.
i.e., this rule element doesn't apply to DEL markers.
This is a breaking change to how ExpiredObejctDeleteAllVersions
functions today. This is necessary to avoid the following highly probable
footgun scenario in the future.
Scenario:
The user uses tags-based filtering to select an object's time to live(TTL).
The application sometimes deletes objects, too, making its latest
version a DEL marker. The previous implementation skipped tag-based filters
if the newest version was DEL marker, voiding the tag-based TTL. The user is
surprised to find objects that have expired sooner than expected.
* Add DelMarkerExpiration action
This ILM action removes all versions of an object if its
the latest version is a DEL marker.
```xml
<DelMarkerObjectExpiration>
<Days> 10 </Days>
</DelMarkerObjectExpiration>
```
1. Applies only to objects whose,
• The latest version is a DEL marker.
• satisfies the number of days criteria
2. Deletes all versions of this object
3. Associated rule can't have tag-based filtering

At server startup, LDAP configuration is validated against the LDAP
server. If the LDAP server is down at that point, we need to cleanly
disable LDAP configuration. Previously, LDAP would remain configured but
error out in strange ways because initialization did not complete
without errors.
When importing access keys (i.e. service accounts) for LDAP accounts,
we are requiring groups to exist under one of the configured group base
DNs. This is not correct. This change fixes this by only checking for
existence and storing the normalized form of the group DN - we do not
return an error if the group is not under a base DN.
Test is updated to illustrate an import failure that would happen
without this change.
Existing IAM import logic for LDAP creates new mappings when the
normalized form of the mapping key differs from the existing mapping key
in storage. This change effectively replaces the existing mapping key by
first deleting it and then recreating with the normalized form of the
mapping key.
For e.g. if an older deployment had a policy mapped to a user DN -
`UID=alice1,OU=people,OU=hwengg,DC=min,DC=io`
instead of adding a mapping for the normalized form -
`uid=alice1,ou=people,ou=hwengg,dc=min,dc=io`
we should replace the existing mapping.
This ensures that duplicates mappings won't remain after the import.
Some additional cleanup cases are also covered. If there are multiple
mappings for the name normalized key such as:
`UID=alice1,OU=people,OU=hwengg,DC=min,DC=io`
`uid=alice1,ou=people,ou=hwengg,DC=min,DC=io`
`uid=alice1,ou=people,ou=hwengg,dc=min,dc=io`
we check if the list of policies mapped to all these keys are exactly
the same, and if so remove all of them and create a single mapping with
the normalized key. However, if the policies mapped to such keys differ,
the import operation returns an error as the server cannot automatically
pick the "right" list of policies to map.
`minio_cluster_webhook_queue_length` was wrongly defined as `counter`

`counter`:
- minio_bucket_replication_sent_bytes
- minio_bucket_replication_received_bytes
- minio_bucket_replication_total_failed_bytes
- minio_bucket_replication_total_failed_count
When LDAP is enabled, previously we were:
- rejecting creation of users and groups via the IAM import functionality
- throwing a `not a valid DN` error when non-LDAP group mappings are present
This change allows for these cases as we need to support situations
where the MinIO server contains users, groups and policy mappings
created before LDAP was enabled.
instead upon any error in renameData(), we still
preserve the existing dataDir in some form for
recoverability in strange situations such as out

RenameData could start operating on inline data after timing out
and the call returned due to WithDeadline.
This could cause a buffer to write to the inline data being written.
Since no writes are in `RenameData` and the call is canceled,

should be fixed.
Copy inline data to a fresh buffer.
This PR makes a feasible approach to handle all the scenarios
that we must face to avoid returning "panic."
Instead, we must return "errServerNotInitialized" when a
bucketMetadataSys.Get() is called, allowing the caller to
retry their operation and wait.
Bonus fix the way data-usage-cache stores the object.
Instead of storing usage-cache.bin with the bucket as
`.minio.sys/buckets`, the `buckets` must be relative
to the bucket `.minio.sys` as part of the object name.
Otherwise, there is no way to decommission entries at
`.minio.sys/buckets` and their final erasure set positions.
A bucket must never have a `/` in it. Adds code to read()
from existing data-usage.bin upon upgrade.

If there are multiple existing DN mappings for the same normalized DN,
if they all have the same policy mapping value, we pick one of them of
them instead of returning an import error.
This is a change to IAM export/import functionality. For LDAP enabled
setups, it performs additional validations:
- for policy mappings on LDAP users and groups, it ensures that the
corresponding user or group DN exists and if so uses a normalized form
of these DNs for storage
- for access keys (service accounts), it updates (i.e. validates
existence and normalizes) the internally stored parent user DN and group
DNs.
This allows for a migration path for setups in which LDAP mappings have
been stored in previous versions of the server, where the name of the
mapping file stored on drives is not in a normalized form.
An administrator needs to execute:
`mc admin iam export ALIAS`
followed by
`mc admin iam import ALIAS /path/to/export/file`
The validations are more strict and returns errors when multiple
mappings are found for the same user/group DN. This is to ensure the
mappings stored by the server are unambiguous and to reduce the
potential for confusion.
Bonus **bug fix**: IAM export of access keys (service accounts) did not
export key name, description and expiration. This is fixed in this
change too.
Reading the list metacache is not protected by a lock; the code retries when it fails
to read the metacache object, however, it forgot to re-read the metacache object
from the drives, which is necessary, especially if the metacache object is inlined.
This commit will ensure that we always re-read the metacache object from the drives
when it is retrying.
When resuming a versioned listing where `version-id-marker=null`, the `null` object would
always be returned, causing duplicate entries to be returned.

This fixes a regression from #19358 which prevents policy mappings
created in the latest release from being displayed in policy entity
listing APIs.
This is due to the possibility that the base DNs in the LDAP config are
not in a normalized form and #19358 introduced normalized of mapping
keys (user DNs and group DNs). When listing, we check if the policy
mappings are on entities that parse as valid DNs that are descendants of
the base DNs in the config.
Test added that demonstrates a failure without this fix.
Create new code paths for multiple subsystems in the code. This will
make maintaing this easier later.
Also introduce bugLogIf() for errors that should not happen in the first
place.
This commit replaces the `KMS.Stat` API call with a
`KMS.GenerateKey` call. This approach is more reliable
since data key generation also works when the KMS backend
is unavailable (temp. offline), but KES has cached the
key. Ref: KES offline caching.
With this change, it is less likely that MinIO readiness
checks fail in cases where the KMS backend is offline.

Make sure to pass a nil pointer as a Transport to minio-go when the API config
is not initialized, this will make sure that we do not pass an interface
with a known type but a nil value.
This will also fix the update of the API remote_transport_deadline
configuration without requiring the cluster restart.
Use `ODirectPoolSmall` buffers for inline data in PutObject.
Add a separate call for inline data that will fetch a buffer for the inline data before unmarshal.
This fixes a bug where STS Accounts map accumulates accounts in memory
and never removes expired accounts and the STS Policy mappings were not
being refreshed.
The STS purge routine now runs with every IAM credentials load instead
of every 4th time.
The listing of IAM files is now cached on every IAM load operation to
prevent re-listing for STS accounts purging/reload.
Additionally this change makes each server pick a time for IAM loading
that is randomly distributed from a 10 minute interval - this is to
prevent server from thundering while performing the IAM load.
On average, IAM loading will happen between every 5-15min after the
previous IAM load operation completes.
If site replication enabled across sites, replicate the SSE-C
objects as well. These objects could be read from target sites
using the same client encryption keys.

Instead of relying on user input values, we use the DN value returned by
the LDAP server.
This handles cases like when a mapping is set on a DN value
`uid=svc.algorithm,OU=swengg,DC=min,DC=io` with a user input value (with
unicode variation) of `uid=svc﹒algorithm,OU=swengg,DC=min,DC=io`. The
LDAP server on lookup of this DN returns the normalized value where the
unicode dot character `SMALL FULL STOP` (in the user input), gets
replaced with regular full stop.
Bonus: remove persistent md5sum calculation, turn-off
sha256 as well. Instead we always enable crc32c which
is enough for payload verification also support for
trailing headers checksum.
