I'm getting lots of journal messages like this:
Feb 21 22:04:33 ubos-container systemd[1]: File /usr/lib/systemd/system/systemd-journald.service:33 configures an IP firewall (IPAddressDeny=any), but the local system does not support BPF/cgroup based firewalling.
Feb 21 22:04:33 ubos-container systemd[1]: Proceeding WITHOUT firewalling in effect!
According to this issue [1]:
Solved by setting CONFIG_BPF_SYSCALL=y in the Linux kernel configuration.
So ... does it make sense to make this the default for future kernels?

I guess I'm too late :-)

You did not specify what kernel or version you were using so I linked the config for the linux kernel in core that already has CONFIG_BPF_SYSCALL so that does not seem to be the cause of your issue.
