The value is the one SIOCINQ returns, so on Hyper-V it covers the current packet only. Accepted sockets inherit the flag from the listener, and the sockmap receive path does not report it. Tested over loopback with vsock_test and vsock_uring_test. v2: - move the SOL_SOCKET options to vsock_sol_socket_setsockopt(), with vsock_custom_sockopt() and a switch on optname (Stefano) - accepted sockets inherit SO_INQ from the listener, as TCP_INQ does (Stefano) - use || instead of | in recvmsg (Stefano) - test: check MSG_CTRUNC and the SCM_INQ cmsg length (Stefano) - test: cover inheritance by accepted sockets v1: https://lore.kernel.org/netdev/20261012235524.41468-1-devnexen@gmail.com/ [1] https://lore.kernel.org/netdev/20260923184008.153541-1-devnexen@gmail.com/ David Carlier (2): vsock: support SO_INQ on stream sockets vsock/test: cover SO_INQ include/net/af_vsock.h | 1 + net/vmw_vsock/af_vsock.c | 111 ++++++++---- tools/testing/vsock/vsock_test.c | 279 +++++++++++++++++++++++++++++++ 3 files changed, 363 insertions(+), 28 deletions(-) base-commit: a4057f51efc2b74ddf46721e83f45e9efb13649d -- 2.55.0
