Two modes of operation being added:
Add two modes of operation:
* For prog load, allow signing a program immediately before loading. This
is essential for command-line testing and administration.
bpftool prog load -S -k <private_key> -i <identity_cert> fentry_test.bpf.o
* For gen skeleton, embed a pre-generated signature into the C skeleton
file. This supports the use of signed programs in compiled applications.
bpftool gen skeleton -S -k <private_key> -i <identity_cert> fentry_test.bpf.o
Generation of the loader program and its metadata map is implemented in
libbpf (bpf_obj__gen_loader). bpftool generates a skeleton that loads
the program and automates the required steps: freezing the map, creating
an exclusive map, loading, and running. Users can use standard libbpf
APIs directly or integrate loader program generation into their own
toolchains.
