cipso_v4_doi_remove(9)

💅 cipso_v4_doi_remove — from the Kernel API Manual

okay so bestie, welcome to the <pink>Kernel API Manual</pink>, this one's cipso_v4_doi_remove(9) and it's literally the "breakup" function of the CIPSO protocol engine 💔✨

---

✨ NAME ✨

cipso_v4_doi_remove — Remove an existing DOI from the CIPSO protocol engine 🫶

---

✨ SYNOPSIS ✨

int cipso_v4_doi_remove (u32 doi , struct netlbl_audit *audit_info );

---

✨ ARGUMENTS ✨

• doi — the DOI value 👑 (yes that's it, that's the whole description, she's mysterious)
• audit_info — NetLabel audit information 🎀

---

✨ DESCRIPTION ✨

So what does she do? She <hotpink>removes a DOI definition from the CIPSO engine</hotpink> 🧚 That's the whole gig. No cap.

The way this works: the NetLabel routines will be called to release their own LSM domain mappings as well as our own domain list 💅 So it's not just a delete-and-dip, bestie, she cleans up after herself. Iconic behavior honestly.

Returns zero on success and negative values on failure 😭 (so like, 0 = slay, negative = not slay).
