skb_flow_get_ports(9)

okay bestie, welcome to the Kernel API Manual page for skb_flow_get_ports(9) — this one is literally about grabbing the upper layer ports and returning them. 💅

💖 NAME 💖

skb_flow_get_ports — extract the upper layer ports and return them. no cap, that's the whole assignment. ✨

✨ SYNOPSIS ✨

here's the signature, kept exactly as-is because we do not mess with code, periodt:

__be32 skb_flow_get_ports (const struct sk_buff *skb , int thoff , u8
       ip_proto , const void *data , int hlen );

🎀 ARGUMENTS 🎀

• skb — the sk_buff to extract the ports from. 🫶
• thoff — the transport header offset.
• ip_proto — the protocol for which to get the port offset.
• data — raw buffer pointer to the packet; if it's NULL, use skb->data.
• hlen — packet header length; if data is NULL, use skb_headlen(skb).

🦋 DESCRIPTION 🦋

the function will try to retrieve the ports at offset thoff + poff, where poff is the protocol port offset returned from proto_ports_offset. that's the tea. ☕
