Patch 1 moves the SOL_SOCKET option handling to a helper without functional change, patch 2 adds SO_INQ and patch 3 covers it in vsock_test. 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. v3: - split the SOL_SOCKET refactor out of the SO_INQ patch (Stefano) - rename vsock_custom_sockopt() to vsock_sol_socket_custom() (Stefano) - parse the value in vsock_sol_socket_get_bool() after the per option checks, so SO_INQ on SOCK_SEQPACKET always fails with ENOPROTOOPT (Stefano) - reflow the comment to 80 columns (Stefano) - carry Reviewed-by and Acked-by on the test patch; Bobby's Acked-by on the v2 kernel patch is dropped since it was split and reworked v2: https://lore.kernel.org/netdev/20261015154334.3217358-1-devnexen@gmail.com/ 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 (3): vsock: move SOL_SOCKET options to vsock_sol_socket_setsockopt() vsock: support SO_INQ on stream sockets vsock/test: cover SO_INQ include/net/af_vsock.h | 1 + net/vmw_vsock/af_vsock.c | 125 ++++++++++---- tools/testing/vsock/vsock_test.c | 279 +++++++++++++++++++++++++++++++ 3 files changed, 377 insertions(+), 28 deletions(-) base-commit: a4057f51efc2b74ddf46721e83f45e9efb13649d -- 2.55.0
