cipso_v4_req_setattr(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

cipso_v4_req_setattr — bestie, this is the one that adds a CIPSO option to a connection request socket ✨

(also hi, this page lives in the Kernel API Manual, so you already know it's kernel-tier 💅)

🦋 SYNOPSIS 🦋

int cipso_v4_req_setattr (struct request_sock *req , const struct
cipso_v4_doi *doi_def , const struct netlbl_lsm_secattr *secattr );

🎀 ARGUMENTS 🎀

  • req — the connection request socket, like the actual socket-in-progress we're doing all this for 🫶
  • doi_def — the CIPSO DOI to use, this is the definition, the blueprint, the moment 👑
  • secattr — the specific security attributes of the socket, i.e. the lore 🌈

💖 DESCRIPTION 💖

Okay so what this does: it sets the CIPSO option on the given socket, using the DOI definition and the security attributes you passed in. Both. Together. Iconic teamwork fr fr 💅

And the return value? Zero on success — slay — and negative values on failure, which is your little sign that it did not, in fact, eat 😭
