[Bug 1886548] [NEW] setcifsacl: fix adding ACE when owner sid in unexpected location
Public bug reported: For Bionic release, current cifs-utils package version is 6.8-1. This version is missing an ACL tools fix that is needed for Azure xSMB. Commit in question which needs to be backported: 0feb1a80f3777f4c244b46958aa9f730de9e18b6 setcifsacl: fix adding ACE when owner sid in unexpected location [Impact] * The bug shows up with mounted cifs/smb filesystem, when a user tries to modify the DACL for the files/directories in the mount. If the owner/group ACEs do not appear first in the DACL (happens quite easily with Azure file shares). The setcifsacl command in cifs-utils fails in that case: $ setcifsacl -a ‘ACL:MYDOMAIN\domuser:DENIED/0x0/FULL’ /mnt/test/abc main: setxattr error: Invalid argument * With the fix available in commit 0feb1a80f3777f4c244b46958aa9f730de9e18b6, the above error is not returned, and the command works. ** Affects: cifs-utils (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886548 Title: setcifsacl: fix adding ACE when owner sid in unexpected location To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/1886548/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
