cipso_v4_parsetag_enum(9)

💖 cipso_v4_parsetag_enum(9) 💖

okay bestie, welcome to the Kernel API Manual page for cipso_v4_parsetag_enum — the CIPSO enumerated-tag parser that is lowkey iconic. ✨

🌸 NAME 🌸

cipso_v4_parsetag_enum — Parse a CIPSO enumerated tag.

🎀 SYNOPSIS 🎀

int cipso_v4_parsetag_enum (const struct cipso_v4_doi *doi_def , const
       unsigned char *tag , struct netlbl_lsm_secattr *secattr );

🦋 ARGUMENTS 🦋

• doi_def — the DOI definition, literally.
• tag — the CIPSO tag.
• secattr — the security attributes.

🌈 DESCRIPTION 🌈

So basically: it parses a CIPSO enumerated tag — tag type #2 — and drops the security attributes into secattr. It returns zero on success, and negative values on failure. That's the whole contract, no cap. 💅
