Description
Hello,
there seems to be some miss-configuration of the eBPF in the kernel.
For example try to run all bpftrace tools that come with the official package of PHOTON,
you will notice most of them failing or not giving any output.
Please activate the following configuration options in the kernel also.
CONFIG_CGROUP_BPF=y
CONFIG_BPFILTER=y
CONFIG_BPFILTER_UMH=m
CONFIG_NET_ACT_BPF=m

Research direction
Inspect the Photon kernel configuration and compare it with the requested CONFIG_CGROUP_BPF, CONFIG_BPFILTER, CONFIG_BPFILTER_UMH, and CONFIG_NET_ACT_BPF settings. Run the bpftrace tools from the official Photon package before and after the configuration change; done means the requested options are enabled and the tools produce their expected output.
