STRUCT IB_SIG_ATTRS(9)

✨ struct ib_sig_attrs(9) ✨

okay so bestie, welcome to struct ib_sig_attrs from the Kernel API Manual — it's literally the vibe-check page for Parameters for signature handover operation 💅 this is where the kernel keeps the deets it needs when it's handing a signature over, and we're gonna walk through every single field together, no skips, no cap 🫶

🌸 NAME 🌸

struct ib_sig_attrs — Parameters for signature handover operation ✨

like, that's it, that's the whole personality: it's the little struct holding the parameters for a signature handover operation 👑

---

🎀 SYNOPSIS 🎀

struct ib_sig_attrs {
    u8 check_mask;
    struct ib_sig_domain    mem;
    struct ib_sig_domain    wire;
    int meta_length;
 };

look at her. four fields. immaculate. main character energy fr fr 🌟

💖 Members 💖

okay so here's the lineup, one by one, exactly as the page says 🧚

• check_mask — bitmask for signature byte check (8 bytes) 🔍 literally a mask of bits, one per signature byte, for checking. eight bytes of it. slay.
• mem — memory domain layout descriptor ✨ the descriptor for the memory domain's layout.
• wire — wire domain layout descriptor 🌈 the descriptor for the wire domain's layout. (yes, mem and wire are a matched set, they're giving duo energy 💜)
• meta_length — metadata length 📏 that's the length of the metadata, bestie.

ngl the whole struct is just these four — check_mask, mem, wire, and meta_length — so if you ever get quizzed on it, you're set 💀

🦋 SEE ALSO 🦋

go read these next, iykyk, they're all in the Kernel file ./include/rdma/signature.h 📚:

• enum ib_signature_type(9)
• enum ib_t10_dif_bg_type(9)
• struct ib_t10_dif_domain(9)
• struct ib_sig_domain(9)

like, the whole signature.h friend group honestly 🫶

🌟 the cute sign-off 🌟

and that's the page, bestie!! 🎀 this little icon came from ./include/rdma, dated October 2026, and she answers to the name struct ib_sig_attrs(9) — periodt 💅✨
