From 79fecc6da7c99ce01181c3ed3effb424c3388f5a Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Fri, 24 May 2024 01:23:55 +0200 Subject: [PATCH] 00438: Fix ThreadedVSOCKSocketStreamTest (GH-119465) (GH-119479) (#119484) Fix ThreadedVSOCKSocketStreamTest: if get_cid() returns the host address or the "any" address, use the local communication address (loopback): VMADDR_CID_LOCAL. On Linux 6.9, apparently, the /dev/vsock device is now available but get_cid() returns VMADDR_CID_ANY (-1).
