💅 x25_parse_facilities(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — grab your strawberry matcha 🍓 because we're about to read some facilities off an skb and it's honestly giving lowkey iconic 🎀

🌸 NAME 🌸

x25_parse_facilities — parses facilities from skb straight into the facilities structs, no cap 🫶

---

✨ SYNOPSIS ✨

int x25_parse_facilities (struct sk_buff *skb , struct x25_facilities
*facilities , struct x25_dte_facilities *dte_facs , unsigned long
*vc_fac_mask );

like literally that's the whole signature, nothing else, periodt 💅

---

🦋 ARGUMENTS 🦋

• skb — the sk_buff we're parsing, bestie. that's the one. 👑
• facilities — the regular facilities 🧚 — this one gets updated as facilities are found, so it's very much main character energy.
• dte_facs — the ITU DTE facilities 🌈 — also updated as DTE facilities are found, same vibe check, different struct.
• vc_fac_mask — the mask 🔥 and yes, it's updated with all facilities found. every single one. it ate.

---

💖 DESCRIPTION 💖

so here's the tea ☕ — the return codes, and you need to know them:

• -1 — Parsing error 😭 the caller should drop the call and clean up. like, pack it up, it's over.
• 0 — Parse OK, but this skb has no facilities. it's giving "nothing to see here" 🙈
• >0 — Parse OK, and it returns the length of the facilities header ⭐ slay.

ngl bestie, if you get that -1 you gotta drop the call and clean up. don't leave it hanging, that's not the move 💀
