📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay so this is the Kernel API Manual page for security_inode_notifysecctx(9), and it's literally about notifying the LSM of an inode's security label 💅

security_inode_notifysecctx — Notify the LSM of an inode's security label.

🌸 SYNOPSIS 🌸

int security_inode_notifysecctx (struct inode *inode , void *ctx , u32
ctxlen );

🎀 ARGUMENTS 🎀

  • inode — inode, bestie 🫶
  • ctx — secctx
  • ctxlen — length of secctx

🦋 DESCRIPTION 🦋

okay so what this does is notify the security module of what the security context of an inode should be. It initializes the incore security context managed by the security module for this inode. Example usage: the NFS client invokes this hook to initialize the security context in its incore inode to the value provided by the server for the file when the server returned the file's attributes to the client. Must be called with inode->i_mutex locked. that part is non-negotiable, bestie 😭

💖 RETURN 💖

Returns 0 on success, error on failure. that's the whole vibe ✨
