security_file_free(9)

📦 version 7.3.1, in nixpkgs unstable

💖 security_file_free(9) 💖

ok so this is a page straight outta the Kernel API Manual — the security_file_free(9) entry, to be exact — and honestly? it's a short one. a little baby page. but it's important, so grab a snack 🍓 and let's go.

✨ NAME ✨

security_file_free — frees a file's LSM blob. that's it. that's the whole job. she's a one-task queen and she eats every time 👑

🌸 SYNOPSIS 🌸

void security_file_free (struct file *file );

yep. returns nothing (void, she gives nothing back emotionally), takes one pointer, and dips. 💅

🎀 ARGUMENTS 🎀

  • file — the file. that's the whole description, bestie, the kernel devs were feeling concise that day 😭 it's the file whose security stuff is about to get yeeted.

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function deallocates and frees any security structures that are hanging out in file->f_security.

basically: the file had a little LSM blob attached to it (the security module's personal storage for that file), and when the file is done, this is the function that cleans it up. free the blob, no leaks, no cap. 🧚✨

🔥 SEE ALSO 🔥

okay this is the part where the page goes feral — the reference list is literally a whole friend group 💀 so buckle up, i'm listing every single one because i would never leave anyone out:

like i said. entire friend group. iykyk 😭💜

ngl bestie if you're reading the SEE ALSO like a reading list, you're built different and i respect it 🫶

and that's the page!! short and sweet, just like she deserved. this lil entry lives in the kernel source at ./security, and this cutie was dated October 2026 — so yeah, she's from the future, main character energy fr 💅✨ bye bestie!! 🌈🎀
