💅 netlbl_domhsh_remove_af4(9) 💅

okay so bestie, you're reading a page from the Kernel API Manual — yes, that Kernel API Manual, the big serious one — and it's about netlbl_domhsh_remove_af4, which lowkey sounds like a wand spell but is actually a kernel function. let's get into it ✨

✨ NAME ✨

netlbl_domhsh_remove_af4 — Removes an address selector entry 🎀

like, it takes an address selector OUT. that's the whole job. slay.

🌸 SYNOPSIS 🌸

int netlbl_domhsh_remove_af4 (const char *domain , const struct in_addr
*addr , const struct in_addr *mask , struct netlbl_audit *audit_info );

so it returns an int, and it takes four things. no cap, that's it. 💜

🦋 ARGUMENTS 🦋

  • domain — the domain. yep. that's the domain. she's the domain. 💅
  • addr — IPv4 address. the address. the actual one.
  • mask — IPv4 address mask. the mask that goes with the address, obviously.
  • audit_info — NetLabel audit information. all the audit tea gets logged here 🍓

🔥 DESCRIPTION 🔥

okay so here's the vibe: this function removes an individual address selector from a domain mapping — and, plot twist, it may also remove the entire mapping if that mapping is empty. yes, she cleans up after herself. main character energy fr fr. 👑

it returns zero on success, and negative values on failure. that's it, that's the contract. don't come for her about it. 😭

💖 SEE ALSO 💖

first up, the source file itself — the Kernel file ./net/netlabel/netlabel_domainhash.c. go read the source bestie, it's giving transparency. 🧚

and then the whole friend group, the entire netlbl_domhsh cinematic universe:

not me listing all seventeen of them 💀 but every single one is here, iykyk. 🫶

one thing — this is kernel code, so pls be normal about it. she returns negative values on failure and she may take the whole empty mapping with her. that's not a bug, that's just her process. 💀

kisses and goodbye from ./net/netlabel, dated October 2026, page netlbl_domhsh_remove_af4(9) — catch you on the flip side bestie, mwah 💋🌈⭐
