Following some update or the other (I think) on my CentOS

Does anyone else see this? It it a bug, or were the
system/default
permissions deliberately changed? Can anyone suggest a
fix/workaround?
Actually, I can find several different ones via a simple web
search, but
they are generally related to other distributions, I'm not
quite sure
which would be the most appropriate for CentOS...
Thanks.

We're waiting for systemd-239-55.el8 sources to show up after
which we
will build this and publish to CentOS Stream. Right now this
appears
to be an infrastructure issue and the appropriate folks are
working on
that, but we also want this package to pass the proper checks
before
we build.
I am doing a compose with this version of systemd in it right
now. Should be released later today.
_______________________________________________
OK .. I am currently releasing an 8-stream compose with
systemd-239-55.el8 .. but it does not fix this unpriv ping issue.
I checked internally and it is also a problem on the rhel build
for this systemd version, so not an issue introduced by the
CentOS Stream build.
This version of systemd should be available in a couple hours on
mirror.centos.org.
OK .. to fix this issue until we get a build that fixes it:
Edit /usr/lib/sysctl.d/50-default.conf
take out the minus sign (-) in this line:
-net.ipv4.ping_group_range = 0 2147483647
Is this "minus" a typo? I guess ...
While yum update i get:
Couldn't write '0 2147483647' to '-net/ipv4/ping_group_range',
ignoring: No such file or directory
I do not know if it is a typo or not (maybe a functionality I don't
know about) .. but if I remove the dash and save the file,
everything works as expected.
It is the only option in that file with a dash.
OK .. the minus sign is intentional .. but the functionality to mkae
it work is not yet in the packages. See this bug for details:
https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.redhat.com%2Fshow_bug.cgi%3Fid%3D2037807&data=04%7C01%7Ctoralf.lund%40pgs.com%7C713021a8ffd245d07c2408d9dce99575%7C51d05d6147e9480b93b298dc84f1ed06%7C0%7C0%7C637783718111185241%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=p2Ym5q6fUiNWSCjBEZbI1l3nf005mRy7aZ27jMlggUU%3D&reserved=0
So the two fixes are to not upgrade iputils and exclude it in your dnf
config .. OR .. to take out he minus sign until the issue is fixed.
Both work for me. Thanks.
Or live with suod/root only for ping
Might also be OK for a short while. Irritation would probably build up
over time ;-)
