Current design: 1. The bpf compiled object name is derived from the source name (e.g. foo.c -> foo.o). 2. Full bpf program/map name are concatenated by object name + '_' + program/map name in run-time. (e.g. obj name: x.o; program name: y_z; full bpf program name will be x_y_z) Issue: x.o with map y_z and x_y.o with map z can cause naming collision in run-time, since both result in x_y_z. This commit prevents it from happening with a build-time check. Bug: 236706995 Test: m Change-Id: Ic03bfcf07a5748ed63246b71d5ae8de0405e658a
