From a57cb3e23d5ac918a69d0aab918470ff0b429ff9 Mon Sep 17 00:00:00 2001 From: John Snow Date: Thu, 18 Nov 2021 15:46:20 -0500 Subject: python/aqmp: fix send_fd_scm for python 3.6.x 3.6 doesn't play keepaway with the socket object, so we don't need to go fishing for it on this version. In fact, so long as 'sendmsg' is still available, it's probably preferable to just use that method and only go fishing for forbidden details when we absolutely have to.
