Subject: Re: [PATCH 3/5] vsock: reuse same-flow socket lookup in RX batches
Date: Sat, 03 Oct 2026 07:46:55 +0000 [thread overview]

> An RX lock batch still looks up the socket for every packet and takes a
> temporary lookup reference, even though the batch already holds a
> reference to the locked socket.
>
> Record the network namespace and packet address tuple when a batch
> starts. Reuse the batch socket for later STREAM/RW packets with the same
> tuple, and release the batch before looking up a different flow.
>
> The cached path still traces every packet, takes an skb owner reference,
> validates socket state, source and transport, updates credit, and runs
> the receive state machine. Only the socket table lookup and its temporary
> reference are skipped.
