netlbl_skbuff_err(9)

💖 netlbl_skbuff_err(9) 💖

okay bestie, this is the Kernel API Manual entry for netlbl_skbuff_err, and we’re folding that manual name in right near the top like a good little header — no copy-paste title line, periodt. 💅

🌸 NAME 🌸

netlbl_skbuff_err — handle a LSM error on a sk_buff 🫶

✨ SYNOPSIS ✨

void netlbl_skbuff_err (struct sk_buff *skb , u16 family , int error ,
       int gateway );

🎀 ARGUMENTS 🎀

• skb — the packet 👀 the actual data vibe we’re handling.
• family — the family 🌱
• error — the error code 🍑
• gateway — true if host is acting as a gateway, false otherwise 🚪✨

🦋 DESCRIPTION 🦋

okay so picture this: there’s a LSM problem while handling the packet in skb, and this function is the one that deals with it. Typically it’s a permission denied problem (-EACCES) 😭. The correct action gets determined according to the packet’s labeling protocol — that’s the assignment, and yes, it’s giving main character energy. 🔥
