5.2.2. Known Issues

Here is the list of known issues in CSIT rls1707 for VPP functional tests in VIRL:

# Issue Jira ID Description
1 DHCPv4 client: Client responses to DHCPv4 OFFER sent with different XID. CSIT-129 Client replies with DHCPv4 REQUEST message when received DHCPv4 OFFER message with different (wrong) XID.
2 Softwire - MAP-E: Incorrect calculation of IPv6 destination address when IPv4 prefix is 0. CSIT-398 IPv6 destination address is wrongly calculated in case that IPv4 prefix is equal to 0 and IPv6 prefix is less than 40.
3 Softwire - MAP-E: Map domain is created when incorrect parameters provided. CSIT-399 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 IPv6 RA: Incorrect IPv6 destination address in response to ICMPv6 Router Solicitation. CSIT-409 Wrong IPv6 destination address (ff02::1) is used in ICMPv6 Router Advertisement packet sent as a response to received ICMPv6 Router Solicitation packet.
5 Vhost-user: QEMU reconnect does not work. CSIT-565 Using QEMU 2.5.0 that does not support vhost-user reconnect. It requires moving CSIT VIRL environment to QEMU 2.7.0.
6 Centos7: LISP and VXLAN sporadic test failures. CSIT-566 Observing sporadic crashes of DUT1 VM during LISP and VXLAN test executions, what leads to failure of all other tests in the suite. NOTE: After upgrading one of the VIRL servers host from Ubuntu14.04 to 16.04, DUT1 VM stops crashing, but tests keep failing sporadically 1-in-100. Possible root cause identified - unexpected IPv6 RA packets upsetting some test component. Currently suspecting environment or CSIT issue, but can not exclude VPP, further troubleshooting in progress.
7 IPSEC: Tests cover old crypto code path CSIT-733 There are used default conf settings so IPSEC tests use old security code not the new Crypto SW code.
