Samuel Cabrero b7810f03ff selftests: Convert "net ads dns async" test to python ... The current test uses the dig tool from bind9 but this tool has been rewritten in 9.17.7 to use bind's netmgr functions instead of isc_socket (commit 94b7988efb0f9b96415dd2966e6070450d960263). The problem is that these 'netmgr' functions use libuv internally, and, on systems supporting it, they end up using the sendmmsg() syscall which is not catched by socket wrapper so the test fails. This commit converts the test to python and uses the dnspython module instead of the dig tool. Backtraces follow as reference.
