xs_error_report(9)

okay bestie, you’ve found the xs_error_report(9) page from the Kernel API Manual 💅✨

🌸 NAME 🌸

xs_error_report — callback to handle TCP socket state errors. that’s the whole job, and it’s lowkey iconic 💖

✨ SYNOPSIS ✨

void xs_error_report (struct sock *sk );

🎀 ARGUMENTS 🎀

• sk — socket. yes bestie, that’s the argument: a socket 🫶

💀 NOTE 💀

⚠️ okay this part matters: xs_error_report does not call sock_error, because there may be an rpc_task using the socket, and so we don’t want to clear sk->sk_err. no touchy the error, bestie 😭
