Description Michael Trapp 2023-04-05 14:04:43 UTC

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

Comment 1 Michael Trapp 2023-04-24 09:23:29 UTC

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.

Comment 2 Michal Hlavinka 2023-04-26 07:37:11 UTC

reassigning to correct component

Comment 3 Karel Zak 2023-04-26 14:32:42 UTC

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 7 Karel Zak 2023-08-16 08:54:01 UTC

@michael.trapp please, can test RHEL-8 backport of the libuuidd cache in your environment? Thanks!

The rhel-8 packages are available at: https://people.redhat.com/kzak/bz2184728/x86_64/

Comment 8 Michael Trapp 2023-08-17 12:35:30 UTC

tested libuuid-2.32.1-43.el8.x86_64.rpm + uuidd-2.32.1-43.el8.x86_64.rpm on RHEL 8.8

Thanks for the backport!
