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. |
+---+-------------------------------------------------+----------+------------------------------------------------------+
