bpf-prog-list. List bpf programs on system.
Well this is a small binary and does what I need, also a good learning exercise.
By default this targets x86_64 since a bare syscall() is used the NR for
SYS_bpf may be different on your machine.
It can be checked by inspecting the preprocessor stage of your compiler by printing
the macro defined in sys/syscall.h:
printf SYS_bpf | gcc -include sys/syscall.h -E -
for clang just swap out gcc command.
