From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stefan Hajnoczi Subject: [PATCH v2 0/5] VSOCK: add sock_diag interface Date: Wed, 4 Oct 2017 12:37:11 -0400 Message-ID: <20171004163716.3964-1-stefanha@redhat.com> Cc: "David S . Miller" , Jorgen Hansen , Dexuan Cui , Stefan Hajnoczi To: netdev@vger.kernel.org Return-path: Received: from mx1.redhat.com ([209.132.183.28]:50440 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1750966AbdJDQh0 (ORCPT ); Wed, 4 Oct 2017 12:37:26 -0400 Sender: netdev-owner@vger.kernel.org List-ID: v2: * Moved tests to tools/testing/vsock/. I was unable to put them in selftests/ because they require manual setup of a VMware/KVM guest. * Moved to __vsock_in_bound/connected_table() to af_vsock.h * Fixed local variable ordering in Patch 4 There is currently no way for userspace to query open AF_VSOCK sockets. This means ss(8), netstat(8), and other utilities cannot display AF_VSOCK sockets. This patch series adds the netlink sock_diag interface for AF_VSOCK. Userspace programs sent a DUMP request including an sk_state bitmap to filter sockets based on their state (connected, listening, etc). The vsock_diag.ko module replies with information about matching sockets. This userspace ABI is defined in . The final patch adds a test suite that exercises the basic cases. Jorgen and Dexuan: I have only tested the virtio transport but this should also work for VMCI and Hyper-V. Please give it a shot if you have time.
