copy_notes_elf32(9)

💫 copy_notes_elf32(9)

okay so bestie, welcome to the Kernel API Manual entry for copy_notes_elf32 — yes that's the function name AND the man page title, we're keeping it, it's iconic 💅

---

✨ NAME ✨

copy_notes_elf32 — literally copies ELF note segments into a buffer you hand it 🎀

---

🌸 SYNOPSIS 🌸

int copy_notes_elf32 (const Elf32_Ehdr *ehdr_ptr , char *notes_buf );

---

🦋 ARGUMENTS 🦋

• ehdr_ptr — the ELF header, bestie. that's the whole vibe of this arg 🫶
• notes_buf — the buffer where all the ELF note segments get copied into ✨

---

💖 DESCRIPTION 💖

so here's the tea: this function copies the ELF note segment from the 1st kernel into the buffer notes_buf in the 2nd kernel. like, it's a whole note-segment handoff between kernels and honestly? slay 🔥

it is assumed that the size of the buffer notes_buf is equal to or larger than the sum of the real ELF note segment headers and data. so pls pls pls make sure your buffer is big enough — no cap, this is a real assumption you gotta satisfy 🙈

also assumed: the program headers with PT_NOTE type pointed to by ehdr_ptr have already been updated by update_note_header_size_elf32. and each of those PT_NOTE program headers has the actual ELF note segment size sitting in its p_memsz member 🧚

so yeah — if you skipped update_note_header_size_elf32, or p_memsz isn't carrying the real note segment size yet, this whole thing is built on vibes that aren't there. do the prep work first, bestie 💀
