v4.1.x

  • v4.1.5
    • Schedule: targeting ~6 mon (Nov 1)
    • No driver on schedule yet.
  • Looks like 5 PRs are reviewed and ready to be merged (https://github.com/open-mpi/ompi/pulls?q=is%3Apr+is%3Aopen+base%3Av4.1.x+)
    • William Would like merged PR#10513
  • Brendan summarized 3 CVEs in libevent 2.0.x series, that are fixed in newer versions of libevent.
    • Discussed a bit on
    • Two of the CVEs are almost certainly NOT built when Open MPI builds libevent.
    • Third CVE is in some search function supporting search (haven't traced if we actually compile it in for Open MPI).
    • Fixed in libevent 2.1.8
    • Fixes DO cherry-pick to libevent embedded in v4.1.x
    • Perception problem, since CVEs are scary.
    • Found this with scans of Open MPI.
  • Would not want to try upgrading libevent to v2.1.8 for v4.1.x
    • Fixes are contained to simple fixes (bounds/range checking fix)
    • Cherry-picks is much less risky
  • Decided Brendan will PR the small cherry-picks needed to v4.1.x and try v4.0.x this week

v5.0.x

  • Schedule:
  • v5.0.x is on libevent 2.1.8 and isn't at risk for CVEs found against v4.1.x
  • PR 10442 needs review for main for session fixes.
    • Biggest OMPI Issue 9869 - external deps on mpirun
      • No one actively working right now. Some iteration a while back.
    • Quite a few doc items
    • Newish issue regarding the partition communication features.
      • Since it's a new feature try to get these in as well.
