🌸 __libeth_xsk_run_prog(9) 🌸

okay bestie, welcome to the Kernel API Manual — this is the page for __libeth_xsk_run_prog, and honestly? it's a little internal gem. 💎

✨ NAME ✨

__libeth_xsk_run_prog — run XDP program on XSk buffer 🏃‍♀️💨

🦋 SYNOPSIS 🦋

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

like, that's the whole signature. no cap. 🤞

🎀 ARGUMENTS 🎀

  • xdp — the XSk buffer you're running the prog on, the main character of this whole operation 💅
  • bq — the buffer bulk, there for the XDP_TX queueing moment 🫶

💖 DESCRIPTION 💖

so basically this is an internal inline abstraction — it's giving "behind the scenes, don't @ me" energy — and its whole job is running the XDP program on the XSk Rx path. 🧚

it handles only the most common XDP_REDIRECT inline, periodt. everything else gets processed externally, so don't come for it about the rest, iykyk. 🙈

and on errors? it reports an XDP prog exception. loud and clear, fr fr. 📣

🔥 RETURN 🔥

it returns the libeth_xdp prog verdict, which depends on the prog's verdict — i.e. whatever the prog decided, that's what you get back. main character energy from the prog, honestly. 👑

💀 no seriously, that's it — the verdict comes from the verdict. the vibes are recursive and we respect it.
