init_inode_smack(9)

📦 version 7.3.1, in nixpkgs unstable

💅 init_inode_smack — Kernel API Manual, section 9

Ok so bestie, we're in the Kernel API Manual (section 9, obvs) and today's main character is init_inode_smack. It's short, it's sweet, it's giving "tiny function, big responsibility" energy. Let's get into it 💖

🌸 NAME

init_inode_smack — initialize an inode security blob ✨

(Yes, that's literally the whole vibe. It initializes. It's a blob. It's inode security. Slay.)

🎀 SYNOPSIS

void init_inode_smack (struct inode *inode , struct smack_known *skp );

No cap, that's the whole signature. Returns nothing (void), takes two pointers, minds its own business. Periodt 🫶

🦋 ARGUMENTS

  • inode — the inode you're extracting the info from. Like, this is the file-system object getting its security blob set up 🗂️
  • skp — a pointer to the Smack label entry to use in the blob. This is the label that gets dropped into the blob, iykyk 🏷️
Two args, zero drama. But like — pointer to a struct inode, pointer to a struct smack_known, and the vibe check is passed. Fr fr.

👑 SEE ALSO

Ok so this is where it gets iconic. The kernel file is ./security/smack/smack_lsm.c and it is stacked with friends. Every single one of these, bestie — I'm not skipping a single one, that would be disrespectful to the source 😤

Like… the entire Smack LSM said "let me introduce you to my whole family" 😭 and honestly? Obsessed. That's the whole neighbourhood right there — inodes, files, creds, tasks, sockets, IPC, keys, audit, uring, and smack_init(9) as the final boss. No skipping, that took effort 💅

🌈 That's the page, bestie! Big love to ./security/smack — that's the source, dated October 2026 — for the lore, and to init_inode_smack(9) for being a tiny function with impeccable main character energy. Go forth and initialize those inode security blobs responsibly. Mwah 💖🎀🦋👑
