** Description changed: [Impact] OEM customers raise this issue, thinking that the error message can be misleading to inexperienced users. [Fix] See attachment and merge proposals. [Test Case] Format a SD card with NTFS, lock the SD card as write-protected, insert the card into the SD card slot. If the card is mounted as read-only, the bug is fixed. [Regression Potential] + To ensure the patch does not cause mounting to fail completely or mounting of writable devices as readonly, verification should include both writable and readonly NTFS partitions. - The fix posted looks shouldn't cause regression. + [Regression testing] + The udisks2 test suite covers both read-only and writable NTFS partitions: + http://cgit.freedesktop.org/udisks/tree/src/tests/integration-test + + You can download it and run it against the installed system binaries; it + will use scsi-debug for a virtual hard disk/CD-ROM, and not touch any of + your real partitions. + + With the current versions in the archive, you get: + + ====================================================================== + ERROR: test_ntfs (__main__.FS) + fs: NTFS + ---------------------------------------------------------------------- + Traceback (most recent call last): + File "src/tests/integration-test", line 636, in test_ntfs + self._do_fs_check('ntfs') + File "src/tests/integration-test", line 758, in _do_fs_check + self._do_udisks_check(type) + File "src/tests/integration-test", line 931, in _do_udisks_check + mount_path = cd_fs.call_mount_sync(no_options, None) + File "/usr/lib/python3/dist-packages/gi/types.py", line 47, in function + return info.invoke(*args, **kwargs) + gi._glib.GError: GDBus.Error:org.freedesktop.UDisks2.Error.Failed: Error + mounting /dev/sr1 at /media/root/2FB591B374B26011: Command-line `mount -t + "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=0,gid=0,dmask=0077,fmask=0177" + "/dev/sr1" "/media/root/2FB591B374B26011"' exited with non-zero exit status 18: + Error opening '/dev/sr1': Read-only file system + Failed to mount '/dev/sr1': Read-only file system + + With the proposed version, the test succeeds. + + If you prefer, you can also run the steps manually; described in + http://bugs.debian.org/686914 [Original Report] Mounting of read only NTFS filesystem gives a following error popup: Cannot mount volume.
