Ok, so I recently landed this: damn das a patch I did this because I saw this and I then wanted to add arm64 support to it.

struct bpf_reg_state (kernel/bpf/bpf_verifier.h) Ok so this isn’t really a function, but rather a struct.

I’ll be analysing BPF JIT today.

Note: This will be a casual blog, so excuse my language.

This patch is currently on it’s v4 and I’m pretty interested in it because I want to try adding ARM JIT support for it.

I was going through verifier.c and found a peculiar global variable struct btf *btf_vmlinux.

I was reading the verifier.c file when I found BPF_FEAT_STREAMS specifically mentioned in the bpf_features enum.

The goal Rn, we gotta understand the working of the verifier and hopefully find errors. bpf_check This is the holy grail where it all starts. bpf_verifier_env is similarly the holy grail struct where it all begins. bpf_features I still do not fully unders…

I found this weird pattern I did not understand in the kernel: static const struct bpf_verifier_ops * const bpf_verifier_ops[] = { #define BPF_PROG_TYPE(_id, _name, prog_ctx_type, kern_ctx_type) \ [_id] = & _name ## _verifier_ops, #define BPF_MAP_TYPE(_i…
