From 9fb7bb06986741b7fd8427fac9f22177ca38dcff Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Tue, 23 Feb 2021 14:46:43 +0000 Subject: libqtest: add qtest_socket_server() Add an API that returns a new UNIX domain socket in the listen state. The code for this was already there but only used internally in init_socket(). This new API will be used by vhost-user-blk-test.
