💅 netlbl_unlhsh_remove(9)

Okay bestie, welcome to the Kernel API Manual page for netlbl_unlhsh_remove — yes that name is a mouthful, no we're not changing it, it's iconic. This is the function that removes an entry from the unlabeled hash table, and honestly? She's giving cleanup crew main character energy. 🧹✨

🌸 NAME 🌸

netlbl_unlhsh_remove — remove an entry from the unlabeled hash table 💖

✨ SYNOPSIS ✨

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

That's the whole signature, copied exactly, not one character changed, periodt. 👑

🎀 ARGUMENTS 🎀

  • net — the network namespace, i.e. which little universe of networking we're operating in 🌈
  • dev_name — the interface name, the actual name of the netdev, not a vibe 💫
  • addr — the IP address, in network byte order (yes, that order, don't @ me) 🦋
  • mask — the address mask, also in network byte order, matching energy 💅
  • addr_len — length of the address and mask: 4 for IPv4, 16 for IPv6 ⭐
  • audit_info — the NetLabel audit information, so the audit trail stays fed 🍓

💜 DESCRIPTION 💜

So what does she do? She removes an existing entry from the unlabeled connection hash table. That's the whole gig. 🫶

Returns zero on success, and negative values on failure — so like, negative vibes mean something went wrong, lowkey important to check. 😭

🔥 SEE ALSO 🔥

The kernel file, bestie, go read it:

  • ./net/netlabel/netlabel_unlabeled.c

And the whole extended friend group, all of them, in order, no cap:

Go off, read the source, remove those entries responsibly. The unlabeled hash table is not gonna clean itself up, and that's literally why this function exists. 💀🌸

And that's a wrap, bestie! 🎀 This came from ./net/netlabel, dated October 2026, and its whole identity is netlbl_unlhsh_remove(9) — slay, take care, bye! 🦋💖✨
