STRUCT KLP_PATCH(9)

✨ struct klp_patch(9) ✨

okay so bestie, welcome to the glow-up era of struct klp_patch — it's the patch structure for live patching, and it's literally the main character of this whole header file 💅

🌸 SYNOPSIS 🌸

struct klp_patch {
    struct module *mod;
    struct klp_object *objs;
    struct klp_state *states;
    bool replace;
    struct list_head list;
    struct kobject kobj;
    struct list_head obj_list;
    bool enabled;
    bool forced;
    struct work_struct free_work;
    struct completion finish;
 };

🎀 Members 🎀

Here's the whole cast, no skips, no cuts 🫶

• mod — reference to the live patch module
• objs — object entries for kernel objects to be patched
• states — system states that can get modified
• replace — replace all actively used patches
• list — list node for global list of actively used patches
• kobj — kobject for sysfs resources
• obj_list — dynamic list of the object entries
• enabled — the patch is enabled (but operation may be incomplete)
• forced — was involved in a forced transition
• free_work — patch cleanup from workqueue-context
• finish — for waiting till it is safe to remove the patch module

ngl bestie, peep that enabled one — enabled does not mean "all done", it means "operation may be incomplete". do not get it twisted 😭
