Description Karel Zak 2023-04-26 14:35:15 UTC 
+++ This bug was initially created as a clone of Bug #2184728 +++

Dear Red Hat team,

we would like to ask wether you could backport the following commit 

https://github.com/util-linux/util-linux/commit/2fa4168c8bc9d5438bc1dfadda293c7c21b6fa59

to the supported RHEL 8/9 versions.
                                                                                                                                                              

Thank you
Michael

Increased severity because, this patch helps to prevent a possible performance degradation of libuuid. Depending on the workflow, uuid consumption is a critical part of a SAP system.

reassigning to correct component

The cache-related changes are relatively small, so from my point of view, it's possible to backport from the current upstream to RHEL (probably by "git diff HEAD upstream --  libuuid/src/gen_uuid.c" as there are more changes than in the commit 2fa4168c8bc9d5438bc1dfadda293c7c21b6fa59).
Comment 2 Michael Trapp 2023-05-31 08:47:25 UTC 
Can you please provide the version info of the fixed libuuid rmps.

The bugfix has not been released yet; it's planned for RHEL 9.3.
Comment 7 Karel Zak 2023-08-16 09:00:58 UTC 
@michael.trapp please, can test RHEL-9 backport of the libuuidd cache in your environment? Thanks!

The rhel-9 packages are available at: https://people.redhat.com/kzak/bz2189947/x86_64
Comment 8 Michael Trapp 2023-08-17 12:38:52 UTC 
tested libuuid-2.37.4-13.el9.x86_64.rpm + uuidd-2.37.4-13.el9.x86_64.rpm on RHEL 9.2

Thanks for the backport!
