sunrpc_nl_un..._reqs_dumpit(9)

okay so bestie, this page is from the Kernel API Manual, and it’s giving “tiny but important kernel netlink dump function” energy. let’s get into it 💅

💖 NAME 💖

sunrpc_nl_unix_gid_get_reqs_dumpit — dump pending unix_gid requests. no cap, that’s the whole name 🫶

✨ SYNOPSIS ✨

int sunrpc_nl_unix_gid_get_reqs_dumpit (struct sk_buff *skb , struct
       netlink_callback *cb );

🎀 ARGUMENTS 🎀

• skb — the reply buffer. that’s where the reply goes 💌
• cb — netlink metadata and command arguments. it’s carrying the netlink context, bestie 🧚

🌸 DESCRIPTION 🌸

So this one walks the unix_gid cache’s pending request list and creates a netlink message with a nested entry for each cache_request, and each of those entries contains the seqno and uid. it’s literally making one cute nested entry per pending request 🔥

It uses cb->args[0] as a seqno cursor for dump continuation across multiple netlink messages — yes, that’s how it keeps its place when the dump spills over into more messages. iconic behavior, honestly ✨

And the return? It returns the size of the reply or a negative errno. that’s it. that’s the vibe check 💀
