Release Notes

Changes in CSIT-1810

  1. TEST FRAMEWORK
    • VPP_Device: Added container based functional VPP device tests integrated into LFN CI/CD infrastructure. VPP_Device tests run on 1-Node testbeds (1n-skx, 1n-arm) and rely on Linux SRIOV Virtual Function (VF), dot1q VLAN tagging and external loopback cables to facilitate packet passing over exernal physical links. Initial focus is on few baseline tests. Existing CSIT VIRL tests can be moved to VPP_Device framework by changing L1 KW(s). L2 KWs and RF test definition code stay unchanged. CSIT VIRL to VPP_Device migration is expected in the next CSIT release.
    • Bug fixes.
  2. CSIT TEST MIMGRATION
    • VPP_Path: Continuing migration of the original FD.io CSIT VIRL tests to VPP-make_test VPP integration tests for functional acceptance of VPP feature path(s) driven by use case(s). See P1 and P2 markup in CSIT_VIRL migration progress

Known Issues

List of known issues in CSIT-1810 for VPP functional tests in VIRL:

# JiraID Issue Description
1 CSIT-129 VPP-99 DHCPv4 client: Client responses to DHCPv4 OFFER sent with different XID. Client replies with DHCPv4 REQUEST message when received DHCPv4 OFFER message with different (wrong) XID.
2 CSIT-398 VPP-380 Softwire - MAP-E: Incorrect calculation of IPv6 destination address when IPv4 prefix is 0. IPv6 destination address is wrongly calculated in case that IPv4 prefix is equal to 0 and IPv6 prefix is less than 40.
3 CSIT-399 VPP-435 Softwire - MAP-E: Map domain is created when incorrect parameters provided. Map domain is created in case that the sum of suffix length of IPv4 prefix and PSID length is greater than EA bits length. IPv6 destination address contains bits writen with PSID over the EA-bit length when IPv4 packet is sent.
4 CSIT-409 VPP-406 IPv6 RA: Incorrect IPv6 destination address in response to ICMPv6 Router Solicitation. Wrong IPv6 destination address (ff02::1) is used in ICMPv6 Router Advertisement packet sent as a response to received ICMPv6 Router Solicitation packet.
5 CSIT-565 Vhost-user: QEMU reconnect does not work. QEMU 2.5.0 used in CSIT does not support vhost-user reconnect. Requires upgrading CSIT VIRL environment to QEMU 2.7.0.
