CI Status

--------------------------------------------------------------------------
UNH-IOL Community Lab

* Ready to deploy an internal system to periodically refresh Docker images
   * This will also update the ABI references to prevent false failures
* Refactoring Jenkins pipelines to increase efficiency of testing
   * We are actively working on reducing the backlog by optimizing allocation of resources within Jenkins
* Bare-metal downtime last week due to:
   * TRex ignoring return values indicating an error
      * This causes segfaults on any card with an xstats count > 0
      * It took a substantial amount of time to track this down
      * Upstream patch generated to TRex: https://github.com/cisco-system-traffic-generator/trex-core/pull/761
   * Changes to DTS since the last update requiring re-testing
* Bare-metal status
   * Mellanox and Broadcom on ARM are non-functional. All other NICs should be reporting up.
   * Mellanox systems updated to the latest versions of TRex (bug above didn’t impact that system), other systems were rolled back to known working versions.
   * Mellanox pass/fail criteria updated to 1.5%, per their request.
   * TRex and a couple of DTS bugs (divide by zero was reintroduced) will need to be patched, before upgrades can proceed.
* FreeBSD 13.0
   * Fix for 1 of the two unit test issues has been submitted: http://patches.dpdk.org/project/dpdk/patch/20210917150917.90892-1-bruce.richardson@intel.com/
* ABI failure 20.11
   * Need to investigate / confirm ABI failure for https://lab.dpdk.org/results/dashboard/tarballs/16879/

--------------------------------------------------------------------------
Intel Lab

* pf_smoke / test_pf_rss test case has been disabled, while waiting for a fix to be merged into the mainline.  Fixed has been merged into next-net, and should be in mainline by the end of the week.  Need to make sure we notify the Intel lab team to re-enable the test.

--------------------------------------------------------------------------
Github Actions & OBS

* OBS working on the final revisions for the patch.
* Github Actions and zero-day bot is currently down.  Server hosting the service had a hardware failure (occurred Monday).  Should be restored by next week.  The team has backups of the VM running the jobs.

==========================================================================
Test Development

* Finished categorizing the feedback DTS.  Creating an Excel (Google Sheet) issue tracker, so developers can be assigned, this may then be ported into Bugzilla
* Next DTS Meeting: TBD

==========================================================================
Any other business

* Next Meeting: October 7, 2021
