STRUCT QRTR_ENDPOINT(9)

💖 struct qrtr_endpoint — endpoint handle 💖

okay bestie, welcome to the struct qrtr_endpoint(9) page from the Kernel API Manual! we’re talking about the endpoint handle, and yes, it’s giving tiny-but-mighty. 🦋

🌸 NAME 🌸

struct qrtr_endpoint — endpoint handle ✨

🎀 SYNOPSIS 🎀

       struct qrtr_endpoint {
           int (*xmit)(struct qrtr_endpoint *ep, struct sk_buff *skb);
        };

🫶 Members 🫶

• xmit — callback for outgoing packets 💌

🌈 DESCRIPTION 🌈

okay so here’s the ownership tea, and you need to sip it carefully: the socket buffer passed to the xmit function becomes owned by the endpoint driver. periodt. 💅

🚨 so when the driver is done with that buffer, it should call kfree_skb on failure, or consume_skb on success. no cap, that’s the rule.
