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.

"sudo dnf downgrade iputils" should do it for now
it works when you're back on iputils-20180629-7.el8.x86_64
And then add:
excludepkgs=iputils-20180629-8.el8.x86_64
in the [baseos] section of /etc/yum/repos.d/CentOS-Stream-BaseOS.repo
Right. After downgrading, I have
$ rpm -q --queryformat '[%{FILENAMES} %{FILECAPS}\n]' iputils | grep
/usr/bin/ping
/usr/bin/ping = cap_net_admin,cap_net_raw+p
I guess this is what was changed in the new version? (Didn't check
before downgrading, to lazy to switch back to do it.)
What I don't quite understand is why the updated iputils was released
before the systemd/kernel changes others mention...
