Need help enabling bpf to mount in sys/fs/bpf

Recommended Posts

I was trying to enable config for bpf in tinker_def_config.

# Bpf config
CONFIG_BPF=y
CONFIG_BPF_SYSCALL=y
CONFIG_BPF_JIT=y
CONFIG_NET_CLS_BPF=y
CONFIG_NET_CLS_ACT=y
CONFIG_NET_SCH_INGRESS=y
CONFIG_CRYPTO_SHA1=y

But came up with these errors:

                 from kernel/bpf/verifier.c:17:
