📦 version 7.3.1, in nixpkgs unstable

💅 netlbl_unlhsh_add(9) — live from the Kernel API Manual 🎀

okay so bestie, welcome to netlbl_unlhsh_add(9), straight out of the Kernel API Manual ✨ this one's a kernel-side function, not a command you type, so no shell prompt energy here — it's for the devs wiring up NetLabel internals 🧚

✨ NAME ✨

netlbl_unlhsh_add — adds a brand new entry to the unlabeled connection hash table 💖 like, it's literally the "put this in the table" function, no cap.

🌸 SYNOPSIS 🌸

int netlbl_unlhsh_add (struct net *net , const char *dev_name , const
void *addr , const void *mask , u32 addr_len , u32 secid , struct
netlbl_audit *audit_info );

she takes seven arguments and returns an int, periodt 💅

🦋 ARGUMENTS 🦋

  • net — the network namespace, aka which little network world we're doing this in 🌈
  • dev_name — the interface name, you know, the device's lil name tag 🎀
  • addr — the IP address, and it's gotta be in network byte order (yes, seriously, network byte order 🫶)
  • mask — the address mask, also in network byte order, matching energy fr fr
  • addr_len — length of the address/mask — it's 4 for IPv4 and 16 for IPv6, iykyk ⭐
  • secid — the LSM secid value for this entry 👑
  • audit_info — the NetLabel audit information, for the receipts 📝

💜 DESCRIPTION 💜

So what she does: adds a new entry to the unlabeled connection hash table 🗂️✨ and that's the whole vibe. Returns zero on success, and negative values on failure — so like, zero is the slay outcome, negatives are the 😭 outcome.

🔥 SEE ALSO 🔥

The kernel file lives at ./net/netlabel/netlabel_unlabeled.c — go read her, she's iconic 👑

and then the whole friend group of related functions, all here, all accounted for 💖:

and that's the whole page bestie 🫶 this one's sourced from ./net/netlabel, dated October 2026, and it's giving kernel API realness 💀✨ mwah, go add some hash entries responsibly 💜
