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.
Add combination of multiple parts.
Parts will be reconstructed and saved separately and can manually be combined to the complete object.
Parts will be named `(version_id)-(filename).(partnum).(in)complete`.
Adds `-xver` which can be used with `-export` and `-combine` to attempt to combine files across versions if data is suspected to be the same. Overlapping data is compared.
Bonus: Make `inspect` accept wildcards.
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)
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
This is to support deployments migrating from a multi-pooled
wider stripe to lower stripe. MINIO_STORAGE_CLASS_STANDARD
is still expected to be same for all pools. So you can satisfy
adding custom drive count based pools by adjusting the storage
class value.

```
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
/minio/metrics/v3/bucket/api/mybucket
Change the existing bucket api endpoint accordingly from /api/bucket to
/bucket/api
The `Token` parameter is a sensitive value that should not be output in the Audit log for STS AssumeRoleWithCustomToken API.
Bonus: Add a simple tool that echoes audit logs to the console.
Algorithms are comma separated.
Note that valid values does not in all cases represent default values.
`--sftp=pub-key-algos=...` specifies the supported client public key
authentication algorithms. Note that this doesn't include certificate types
since those use the underlying algorithm. This list is sent to the client if
it supports the server-sig-algs extension. Order is irrelevant.

`--sftp=kex-algos=...` specifies the supported key-exchange algorithms in preference order.

`--sftp=cipher-algos=...` specifies the allowed cipher algorithms.
If unspecified then a sensible default is used.

`--sftp=mac-algos=...` specifies a default set of MAC algorithms in preference order.
This is based on RFC 4253, section 6.4, but with hmac-md5 variants removed because they have
reached the end of their useful life.

endpoint: /minio/metrics/v3/system/process
metrics:
- locks_read_total
- locks_write_total
- cpu_total_seconds
- go_routine_total
- io_rchar_bytes
- io_read_bytes
- io_wchar_bytes
- io_write_bytes
- start_time_seconds
- uptime_seconds
- file_descriptor_limit_total
- file_descriptor_open_total
- syscall_read_total
- syscall_write_total
- resident_memory_bytes
- virtual_memory_bytes
- virtual_memory_max_bytes
Since the standard process collector implements only a subset of these
metrics, remove it and implement our own custom process collector that
captures all the process metrics we need.
Since the object is being permanently deleted, the lack of read quorum should not
matter as long as sufficient disks are online to complete the deletion with parity
requirements.
If several pools have the same object with insufficient read quorum, attempt to
delete object from all the pools where it exists
When inspecting files like `.minio.sys/pool.bin` that may be present on multiple sets, use signature to separate them.
Also fixes null versions to actually be useful with `-export -combine`.
instead upon any error in renameData(), we still
preserve the existing dataDir in some form for
recoverability in strange situations such as out
of disk space type errors.
Bonus: avoid running list and heal() instead allow
versions disparity to return the actual versions,
uuid to heal. Currently limit this to 100 versions
and lesser disparate objects.
an undo now reverts back the xl.meta from xl.meta.bkp
during overwrites on such flaky setups.
Bonus: Save N depth syscalls via skipping the parents
upon overwrites and versioned updates.
Flaky setup examples are stretch clusters with regular
packet drops etc, we need to add some defensive code
around to avoid dangling objects.
Keep the EC in header, so it can be retrieved easily for dynamic quorum calculations.
To not force a full metadata decode on every read the value will be 0/0 for data written in previous versions.
Size is expected to increase by 2 bytes per version, since all valid values can be represented with 1 byte each.
Example:
```
λ xl-meta xl.meta
{
"Versions": [
{
"Header": {
"EcM": 4,
"EcN": 8,
"Flags": 6,
"ModTime": "2024-04-17T11:46:25.325613+02:00",
"Signature": "0a409875",
"Type": 1,
"VersionID": "8e03504e11234957b2727bc53eda0d55"
},
...
```
Not used for operations yet.
As node metrics should be scraped per node basis, use a sample
configuartion using all the nodes in targets.

When no results match or another error occurs, add an error to the stream. Keep the "inspect-input.txt" as the only thing in the zip for reference.
Example:
```
λ mc support inspect --airgap myminio/testbucket/fjghfjh/**
mc: Using public key from C:\Users\klaus\mc\support_public.pem
File data successfully downloaded as inspect-data.enc
λ inspect inspect-data.enc
Using private key from support_private.pem
output written to inspect-data.zip
2024/04/11 14:10:51 next stream: GetRawData: No files matched the given pattern
λ unzip -l inspect-data.zip
Archive: inspect-data.zip
Length Date Time Name
--------- ---------- ----- ----
222 2024-04-11 14:10 inspect-input.txt
--------- -------
222 1 file
λ
```
Modifies inspect to read until end of stream to report the error.
Bonus: Add legacy commandline params
Add following metrics:
- used_inodes
- total_inodes
- healing
- online
- reads_per_sec
- reads_kb_per_sec
- reads_await
- writes_per_sec
- writes_kb_per_sec
- writes_await
- perc_util
To be able to calculate the `per_sec` values, we capture the IOStats-related
data in the beginning (along with the time at which they were captured),
and compare them against the current values subsequently. This is because
dividing by "time since server uptime." doesn't work in k8s environments.
