Hi all

Maybe someone run's into same issue - here my workaround:

"zypper ps -sss" don't work as expected after upgrade 15.5 to 15.6

My system:
* proxmox 8.2 up-to-date
* LXC unprivileged
* LXC nesting=1
* upgrade opensuse 15.5 -> 15.6, and upgraded, minimal system (238 rpm packages)
Important news:
- systemd 249 -> 254
- glibc 2.31 -> 2.38
- SE-Linux disabled (default)

After upgrade some containers (LXC) based on openSUSE 15.5 to openSUSE 15.6 all works fine and all services running as expected. Seems perfect.
After some days later and newer updates "zypper ps -sss| xargs systemctl restart " always tried to restart same services again and again , eg systemd-logind,postfix
on this minimalistic environment.

(loop)
# zypper ps -sss| xargs -r systemctl restart

# zypper ps -s
postfix
systemd-logind

# zypper ps -s

The following running processes use deleted files:

....

I find out, that package only "lsof" (changed during upgrade on openSUSE from 4.91 to 4.99, some small changes against libselinux ??) produced these output.

# id -a
uid=0(root) gid=0(root) groups=0(root)

# lsof -p $(pgrep master) ... > "Operation not permitted" ... !!????

# rpm -q --changelog lsof
* Sat Nov 11 2023 andreas.stieger@gmx.de
- lsof 4.99.0:
* Do not hard-code fd numbers in epoll test
* --with-selinux configure option.
* Improve performance by using closefrom()
* Introduce liblsof for programmatic access over spawning lsof
in a subprocess
- build with libtirpc
- switch to upstream tarball again as it dropped proprietary code
....

Workaround:
Backport LSOF from 4.99 (openSUSE15.6) to 4.91 (openSUSE15.5)

Btw:
VMs not affected / bare-metal systems not affected

Mfg/Regards
 
Hey there,

thank you for the analysis, running into the same issue in my Ansible playbooks.
Could you specify the steps to install the backported version of lsof?
I only get version 4.99 when I run zypper se -s lsof.

EDIT:
For reference my repos:
Code: 
ansible:/ansible # zypper lr

Hello,

for somebody to search the same question how to backport this ... here is the solution:
Code: 
echo -e '[lsof-bug]\nname=lsof is bugged, that is why this repo is here\nenabled=1\nautorefresh=1\nbaseurl=http://download.opensuse.org/distribution/leap/15.5/repo/oss/' > /etc/zypp/repos.d/lsof-bug.repo
zypper ref
zypper install --oldpackage lsof-4.91-1.11.x86_64
zypper al lsof

Best regards,
Ex
