[PATCH net-next 0/2] vsock: SO_INQ for stream sockets

From: David Carlier

Date: Mon Oct 12 2026 - 19:55:44 EST


This is the follow-up announced in the receive queue hint series [1]:
SO_INQ and SCM_INQ for AF_VSOCK stream sockets, as AF_UNIX has.

The value is the one SIOCINQ returns, so on Hyper-V it covers the
current packet only. The flag is per socket, is not inherited by
accepted sockets, and the sockmap receive path does not report it.

Tested over loopback with vsock_test and vsock_uring_test.
