security_netif_sid(9)

📦 version 7.3.1, in nixpkgs unstable

💖 security_netif_sid 💖

okay so bestie, welcome to the Kernel API Manual entry for security_netif_sid — yes that's the whole title, and yes it's a (9) page, meaning it's a kernel-internals situation, not your usual "how do I list files" moment. This one's short and sweet: it's literally just "hey, what's the SID for this network interface?" ✨

🌸 NAME 🌸

security_netif_sid — obtain the SID for a network interface. that's it, that's the whole job. no cap. 🎀

🦋 SYNOPSIS 🦋

int security_netif_sid (const char *name , u32 *if_sid );

like, look at that. three tokens of pure main-character energy. 💅

✨ ARGUMENTS ✨

  • name — the interface name, bestie. it's a const char *, so it's just lookin' at the string, not touching it. 🫶
  • if_sid — the interface SID. it's a u32 *, so this is where the answer gets written back. lowkey the whole point. 👑

🌈 SEE ALSO 🌈

okay this is the part where the page goes absolutely feral with cross-references, and i am not skipping a single one, because the way that this list just keeps going is honestly iconic. 🔥

first up, the kernel file itself:

  • Kernel file ./security/selinux/ss/services.c

and then the whole friend group:

like… twenty-six siblings. twenty-six!! a whole extended family of SID-related manpages and this one is just the netif one. iykyk. 💀💜

oh and btw — the double-underscore ones (__security_genfs_sid(9), __security_read_policy(9)) are not typos, that's literally their names, so copy them exactly if you're grepping. 🙈

that's the whole page, bestie — short, specific, and extremely on brand. 🧚

this lil writeup is straight outta the ./security/selinux/ss corner of the kernel and it's dated October 2026, so go forth and get your interface SIDs, you gorgeous nerd. slay. 💖⭐🌸🍓
