[Bug 2055226] Re: mount option `users` blocks ntfs to mount
In the latest man pages I recently found: Since util-linux 2.35, mount does not exit when user permissions are inadequate according to libmount’s internal security rules. Instead, it drops suid permissions and continues as regular non-root user. This behavior supports use-cases where root permissions are not necessary (e.g., fuse filesystems, user namespaces, etc). With this new rule the "regression" concerning `mount` is explainable. So please add a link to this note at the description of the `user(s)` options. Still existing: The buggy behaviour with `udisksctl mount`. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055226 Title: mount option `users` blocks ntfs to mount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/2055226/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2055226] Re: mount option `users` blocks ntfs to mount
Both options and a third exist. Extract from man mount in section FILESYSTEM-INDEPENDENT MOUNT OPTIONS: user Allow an ordinary user to mount the filesystem. The name of the mounting user is written to the mtab file (or to the private libmount file in /run/mount on systems without a regular mtab) so that this same user can unmount the filesystem again. This option implies the options noexec, nosuid, and nodev (unless overridden by subsequent options, as in the option line user,exec,dev,suid). nouser Forbid an ordinary user to mount the filesystem. This is the default; it does not imply any other options. users Allow any user to mount and to unmount the filesystem, even when some other ordinary user mounted it. This option implies the options noexec, nosuid, and nodev (unless overridden by subsequent options, as in the option line users,exec,dev,suid). gio mount is the command line variant to simulate a mount by a GUI tool like Nautilus, just used to get the error message. gio invokes udiskctl under the hood. ** Changed in: util-linux (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055226 Title: mount option `users` blocks ntfs to mount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/2055226/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2055226] Re: mount option `users` blocks ntfs to mount
Hello, thanks for the report; note that the fstab(5) and mount(8) man pages both say "user", singular, not "users", plural. That's probably why your mount command didn't work when run as a user. I don't know about the gio or udisksctl tool errors, I'm unfamiliar with their operation. Maybe they were also looking for "user"?
