From a37c07022b44e4fc29238deca7588406d081e6c2 Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Tue, 3 Jan 2017 17:28:44 +0100 Subject: [PATCH] tests: virtio-9p: ".." cannot be used to walk out of the shared directory According to the 9P spec at http://man.cat-v.org/plan_9/5/intro, the parent directory of the root directory of a server's tree is itself. This test hence checks that the qid of the root directory as returned by attach is the same as the qid of ".." when walking from the root directory.
