I ran into this link error with the latest net-next plus linux-next trees when networking is disabled:kernel/bpf/verifier.o:(.rodata+0x2958): undefined reference to `tc_cls_act_analyzer_ops' kernel/bpf/verifier.o:(.rodata+0x2970): undefined reference to `xdp_analyzer_ops' It seems that the code was written to deal with varying contents of the arrray, but the actual #ifdef was missing. Both tc_cls_act_analyzer_ops and xdp_analyzer_ops are defined in the core networking code, so adding a check for CONFIG_NET seems appropriate here, and I've verified this with many randconfig builds Fixes: 4f9218aaf8a4 ("bpf: move knowledge about post-translation offsets out of verifier") Signed-off-by: Arnd Bergmann <[email protected]>
