errors rebuilding kernel with bpf config #15

Open wahahawasabi opened 2 years ago

wahahawasabi commented 2 years ago

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:
