__libeth_xdp_run_prog(9)

🦋 NAME

__libeth_xdp_run_prog — bestie, it runs an XDP program on an XDP buffer ✨ (this is from the Kernel API Manual, for the record)

🌸 SYNOPSIS

u32 __libeth_xdp_run_prog (struct libeth_xdp_buff *xdp , const struct
libeth_xdp_tx_bulk *bq );

🎀 ARGUMENTS

• xdp — the XDP buffer you're running the prog on. that's the main character of this whole thing 💅
• bq — the buffer bulk used for `XDP_TX` queueing 🫶

💖 DESCRIPTION

Okay so this one is an internal inline abstraction whose entire job is to run the XDP program. It handles `XDP_DROP` and `XDP_REDIRECT` only — everything else gets processed levels up, no cap. 🙈

Also, on errors it reports an XDP prog exception. So like, it will tell on you, but lovingly. 😭

⭐ RETURN

Returns the libeth_xdp prog verdict, depending on the prog's verdict. Yes bestie, the verdict decides the verdict — it's giving "the vibes decide the vibes" but make it kernel code 🔥
