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 Kai Engert (:kaie) (inactive account) 2018-03-07 18:36:23 UTC 
The nss-softokn package for RHEL 7.5.0 contains a behavior change, which affects NSS applications that access NSS databases of the SQL type that are stored on network filesystems.

Previously, in RHEL 7.4.x and earlier, NSS performed automatic probing of the filesystem speed at startup time. This allowed NSS to automatically enable a speed/caching optimization.

In the upstream NSS version that 7.5.0 ships, this probing was disabled. We hadn't notice that change.

I'd like to recommend that we undo that accidental change in RHEL 7.5.0, and restore the previous behavior. This can avoid regression bug reports from RHEL 7.x users.

The fix is simple, a very small upstream patch needs to be reverted.

A good opportunity to fix this is the rebase of nss-softokn that is planned for Firefox 60 and 7.5.z, see bug 1531060 and 1550045.
