Enhancements in 5.1.0-SP4

Networking

ORION-173773: For clusters that use InfiniBand networking on the internal interfaces, the OpenSM service will now be automatically enabled on the cluster’s CNodes after a VAST OS upgrade.

S3

ORION-180193: Added the following user controls to turn on or off S3 Signature V2 authentication:
- In VAST CLI, the --enable-s3-block-v2-authentication and --disable-s3-block-v2-authentication options on the cluster create command
- In VAST REST API, the s3_block_v2_authentication parameter for the /clusters/ endpoint.

VMS

ORION-179577: Capacity values reported in VMS capacity validation messages during DBox migration are now in terabytes, indicated by TB. Previously, the values were in bytes.
ORION-176657: Removed the options to enable and disable a view from VAST Web UI and VAST REST API.

VAST REST API

ORION-172534: The /api/capacity/capacity_estimation/ endpoint now features a new separatorparameter that lets you specify a custom separator character for a list of paths:
```
/api/capacity/capacity_estimation/?format=api&path=<list of paths>&separator=<separator>
```
Prior to this change, the endpoint only accepted comma-separated lists of paths where directory or file names could not contain a comma.

VAST OS

ORION-172104: VAST OS now includes the OpenSCAP toolkit that lets you run configuration and vulnerability scans on your VAST cluster.

To perform a scan, ssh to the VAST cluster and run oscap, for example:

sudo oscap xccdf eval --profile xccdf_org.ssgproject.content_profile_stig_gui \
                      --cpe /usr/share/xml/scap/ssg/content/ssg-rhel8-cpe-dictionary.xml \
                      --fetch-remote-resources \
                      --oval-results --results-arf /tmp/arf.xml \
                      --report /tmp/report.html \
                      /usr/share/xml/scap/ssg/content/ssg-rl8-xccdf.xml

For how-to details on oscap, see the OpenSCAP User Manual.

Caution
Do not remediate the cluster with oscap.
