RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Neal Gompa 2022-05-18 15:46:07 UTC 
+++ This bug was initially created as a clone of Bug #2087734 +++

Description of problem:
Image build tools that use the DNF Python API directly have issues completing successfully right now because the Base object leaks page file descriptors, which locks up all the mounts and prevents successful filesystem unmounting to save the final disk.

This was fixed upstream as https://github.com/rpm-software-management/dnf/commit/5ce5ed1ea08ad6e198c1c1642c4d9ea2db6eab86

Please backport this so that this problem is fixed.

Version-Release number of selected component (if applicable):
4.10.0-5.el9_0

Additional info:
This was reported to livecd-tools here: https://github.com/livecd-tools/livecd-tools/issues/232
Comment 1 Richard W.M. Jones 2022-05-18 16:08:31 UTC 
I can do dev work here, but someone on the packaging team will need to do QE.
Obviously dnf is quite an important package so we can't leave it to chance.
Very low risk of regressions as far as we know.
Comment 3 Richard W.M. Jones 2022-05-23 13:12:42 UTC 
Yeah that'll be fine.  It's more important that we don't break dnf than
that we prove that livecd-tools is fixed :-)
Comment 4 Richard W.M. Jones 2022-05-23 17:42:05 UTC 
The baseos-ci.brew-build.ci-dnf-stack-gating.functional test failed with:

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
::   Test plugins-core/modulesync.feature
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

:: [ 17:09:42 ] :: [   FAIL   ] :: Command './container-test  run --container-arg='--security-opt' --container-arg='seccomp=unconfined' plugins-core/modulesync.feature' (Expected 0, got 1)
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
::   Duration: 3s
::   Assertions: 0 good, 1 bad
::   RESULT: FAIL (Test plugins-core/modulesync.feature)

whatever that means.  I can't believe it would be caused by this change.
Also I don't know where these tests are located.
Comment 5 Neal Gompa 2022-05-23 23:05:15 UTC 
I believe the tests come from here: https://github.com/rpm-software-management/ci-dnf-stack
Comment 6 Richard W.M. Jones 2022-05-24 09:47:01 UTC 
I ran the test 3 times and it failed each time.  It did not fail
on the previous build of this package in RHEL 9.  I don't have a
theory as to why this particular patch could cause a failure in
this particular test.  (The failure might also be caused by environment
changes, so this patch might not be the cause.)

Needs someone who is more familiar with the tests to look at this.

At the moment I don't want to waive this test, given such an important
RHEL package.
Comment 7 Richard W.M. Jones 2022-05-24 09:47:36 UTC 
OSCI tests are here FYI:

Comment 14 Pablo Greco 2022-05-30 17:36:11 UTC 
Any chance of this being backported into 9.0? it's creating problems for users trying to generate images
Comment 15 Richard W.M. Jones 2022-05-30 20:01:45 UTC 
I set zstream=? flag which should cause this bug to be evaluated for
9.0.z, but for some reason it's being ignored.
