STRUCT KLP_OBJECT(9)

💅 struct klp_object(9) — the kernel API manual, bestie edition 💅

okay so this is the manual page for struct klp_object(9), which lives in the Kernel API Manual fam. It's literally the kernel object structure for live patching — like, this little struct is the main character of "which thing are we patching rn". No cap. 👑

✨ NAME ✨

struct klp_object — kernel object structure for live patching 🫶

---

🌸 SYNOPSIS 🌸

struct klp_object {
    const char *name;
    struct klp_func *funcs;
    struct klp_callbacks callbacks;
    struct kobject kobj;
    struct list_head func_list;
    struct list_head node;
    struct module *mod;
    bool dynamic;
    bool patched;
 };

🎀 Members 🎀

• name — the module name, or NULL for vmlinux. that's it, that's the assignment 💖
• funcs — function entries for functions to be patched in the object. the actual to-do list, basically ✨
• callbacks — functions to be executed pre/post (un)patching. before and after vibes 🦋
• kobj — kobject for sysfs resources. the sysfs hookup 🌸
• func_list — dynamic list of the function entries 💅
• node — list node for klp_patch obj_list 🎀
• mod — kernel module associated with the patched object (NULL for vmlinux). yeah, same NULL-for-vmlinux energy as name 🙈
• dynamic — temporary object for nop functions; dynamically allocated. temporary queen, allocated on the fly ⭐
• patched — the object's funcs have been added to the klp_ops list. it's official now, periodt 🔥

💀 friendly reminder that this is a members breakdown, so every field above is doing real work — don't touch patched or dynamic unless you actually know what you're doing, iykyk 🧚
