From 1a98cd52b5771243cd5662e19c2162f45f09f96a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20Calvi=C3=B1o=20S=C3=A1nchez?= Date: Mon, 9 Sep 2024 13:07:14 +0200 Subject: [PATCH 1/2] fix: Fix copying or moving from shared groupfolders MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When copying or moving between two local storages the source path (on disk) to copy or move from is got from the unjailed path of the source storage. However, if the source storage has more than one jail getting the unjailed path resolves the most external jail, but the source path needs to be got from the most internal jail instead (the one closer to the local storage). This can happen, for example, with a shared groupfolder: in that case there is an external jail for the shared storage, and one internal jail for the groupfolder storage wrapped by the shared storage.
