Testing

-------



Next to the BPF toolchain, the kernel also ships a test module that contains

various test cases for classic and internal BPF that can be executed against

the BPF interpreter and JIT compiler. It can be found in lib/test_bpf.c and

enabled via Kconfig:



  CONFIG_TEST_BPF=m



After the module has been built and installed, the test suite can be executed

via insmod or modprobe against 'test_bpf' module. Results of the test cases

including timings in nsec can be found in the kernel log (dmesg).
