v1.4.0

UPG v1.4.0 release

Policy-based Routing

UPF forwarding policy can be used to specify routing path for particular session.
If Forwarding parameters has Forwarding Policy ID, appropriate UPF
policy with same ID will be applied to override forwarding applied
by FAR (ignoring FAR Network Instance) and using routing paths
configured for UPF forwarding policy.
Forwarding Policy applies for both IPv4 and IPv6, using the same Policy ID.
Forwarding Policy can be applied in forwarding and proxy mode.
Display forwarding policy in "show upf session"

Build UPG as an external VPP plugin

• upf plugin is now build as vpp plugin and packages as deb file

GTPU Error Indication

When UPG receives a G-PDU for which no corresponding GTP-U tunnel
exists, it must discard the G-PDU and return a GTP-U Error Indication
to the sending node.

Fix NAT Binding Port range calculation

Since port range should be exactly block_size length and start port
is included into it, calculation of end port was incorrect.
Actual calculation for binding is correct, however value for report to
CP-F should be fixed.

Add binary API for NWI and PFCP endpoint configuration

To enable runtime reconfiguration, binary API was introduced for:

• NWI creation
• PFCP endpoint definition
• PFCP server configuration
• Forwarding Policy definition

Fix crash in upf_pfcp_error_report()

• Before the fix, segmentation fault happened in upg-vpp

Fix error handling in "upf ueip pool" CLI command

• Handles UE IP pool already exists and UE IP pool does not exist

Enable interrupt-driven mode for NIC driver handling

• Instead of poll mode
• Used in e2e tests, reducing errors in CI
