CSIT Release Notes ================== Changes in CSIT |release| ------------------------- #. VPP functional test framework changes: - Upgrade of tb4-virl1 and tb4-virl2 hosts; - OS version to Ubuntu 16.04.02; - VIRL version to Mitaka; - Implemented load balance mechanism for VIRL hosts; - Implemented waiting mechanism on VIRL host if there is not enough resources available to successfully start simulation; #. Code updates and optimizations in CSIT functional framework: - Complete CSIT framework code revision and optimizations as descried on CSIT wiki page _`Design_Optimizations `_; - For more detail see the CSIT Framework Design section in this report; Known Issues ------------ Here is the list of known issues in CSIT |release| for VPP functional tests in VIRL: +---+-------------------------------------------------+----------+------------------------------------------------------+ | # | Issue | Jira ID | Description | +---+-------------------------------------------------+----------+------------------------------------------------------+ | 1 | DHCPv4 client: Client responses to DHCPv4 OFFER | CSIT-129 | Client replies with DHCPv4 REQUEST message when | | | sent with different XID. | | received DHCPv4 OFFER message with different (wrong) | | | | | XID. | +---+-------------------------------------------------+----------+------------------------------------------------------+ | 2 | Softwire - MAP-E: Incorrect calculation of IPv6 | CSIT-398 | IPv6 destination address is wrongly calculated in | | | destination address when IPv4 prefix is 0. | | case that IPv4 prefix is equal to 0 and IPv6 prefix | | | | | is less than 40. | +---+-------------------------------------------------+----------+------------------------------------------------------+ | 3 | Softwire - MAP-E: Map domain is created when | CSIT-399 | Map domain is created in case that the sum of suffix | | | incorrect parameters provided. | | 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 | CSIT-409 | Wrong IPv6 destination address (ff02::1) is used in | | | response to ICMPv6 Router Solicitation. | | 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 | -- | There are used default conf settings so IPSEC tests | | | | | use old security code not the new Crypto SW code. | +---+-------------------------------------------------+----------+------------------------------------------------------+
