FUNCTION::KERNEL_BUFFER_QUOTED(3stap)

💖 function::kernel_buffer_quoted — like, the whole vibe

okay bestie, settle in, because this one is from the SystemTap Tapset Reference (that's the 3stap manual, iykyk) and it's literally about pulling a buffer out of kernel space and wrapping it in lil quotation marks. adorable. iconic. let's go. ✨

---

🌸 NAME 🌸

function::kernel_buffer_quoted — retrieves and quotes a buffer from kernel space 🫶

---

✨ SYNOPSIS ✨

so there's two whole flavors, pick ur fighter:

1) kernel_buffer_quoted:string(addr:long,inlen:long)

2) kernel_buffer_quoted:string(addr:long,inlen:long,outlen:long)

---

🎀 ARGUMENTS 🎀

• addr — the kernel space address you're snatching the buffer from. that's the spot. 📍
• inlen — the exact length of the buffer to read. exact, bestie. no rounding, no vibes-based guessing.
• outlen — the maximum length of the output string. it's giving "know ur limits" 💅

---

🦋 DESCRIPTION 🦋

version 1, the classic 💜

Reads inlen characters of a buffer from the given kernel space memory address, and hands you back up to MAXSTRINGLEN characters. Any ASCII characters that aren't printable? they get swapped out for the corresponding escape sequence in the returned string. no chaos allowed. 🚫

and listen — the string comes surrounded by double quotes. that's the whole point of the _quoted in the name, she's doing her job. 🎀

but here's the rare-case tea: when kernel space data is not accessible at the given address, the address itself gets returned as a string, without double quotes. so if you see a bare address just sitting there with no quotes, that's what happened. 🙈

version 2, the one with extra control ✨

Reads inlen characters of a buffer from the given kernel space memory address, and this time returns up to outlen characters (yes, you get to choose the cap, main character energy 👑). Same deal with the ASCII: anything not printable gets replaced by the corresponding escape sequence in the returned string.

and again — the string will be surrounded by double quotes. 💖

and again, the rare case: when kernel space data is not accessible at the given address, the address itself is returned as a string, without double quotes. keep that in mind, fr fr. 😭
