[Bug 2090931] Re: DPDK 24.11 unconditional increase in resident memory use for linked binaries

[Christian Ehrhardt ]

Glad you were able to fix it in OVS, I've seen your discussion upstream in DPDK channels.
Setting DPDK as invalid since the fix will be in OVS and OVS only.

** Changed in: dpdk (Ubuntu)
       Status: New => Invalid

Title:
  DPDK 24.11 unconditional increase in resident memory use for linked
  binaries

Status in dpdk package in Ubuntu:
  Invalid
Status in openvswitch package in Ubuntu:
  Fix Committed

Bug description:
  The likely cause is that DPDK 24.11 contains a commit [0] adding per-
  lcoe static memory allocation facility.

  The not so desirable side effect is however that every binary linked
  with DPDK gets affected, regardless of them initializing the library
  or not.

  This has presented itself as an issue for Open vSwitch, where the
  build time tests no longer passes in Salsa CI due to the test runner
  going OOM for the "monitor-cond-change with many sessions pending"
  test.

  Raised the issue in #openvswitch on Libera chat, and there were some
  constructive discussions on the back of it.

  Recording this bug for now to document temporary disabling of failing
  test in the name of getting to check for any other issues.
