- fix crash in do_resizepart
+ parted-fix-end_input-usage.patch: Fix end_input usage in
do_resizepart
- update to version 3.3, noteworthy changes:
- s390: Re-enabled virtio-attached DASD heuristics by using
HDIO_GETGEO when probing device geometry. Fixes a bug with
KVM virtio-blk backed by a DASD.
Parted now recognizes NVMe devices, NVDIMM, and RAM drives.
- Fix atari disklabel false positives by probing other labels first.
- Fix resizepart to adjust the end to be -1 sector when using iec
power of 2 units so that the next partition can start immediately
following the new end, just like mkpart does.
- Fix set and disk_set to not crash when there are no flags to set.
- Fix a udev cookie leak when using resizepart on device-mapper devices.
- Fix a gettext crash/error sometimes when using localized languages.
- Fix fat resize to preverve boot code, and thus not render the
filesystem unreconized by Windows.
- Fix rescue command: the rescue command often failed to find
filesystems due to leaving on cylinder alignment.
- libparted-fs-resize: Prevent crash resizing FAT file systems with very
deep directories with path names over 512 bytes long.
- Use 512b sector size when communicating with device-mapper. Fixes
problems with partitions being created too small on dm devices
with sector sizes > 5121b
- Don't crash in the disk_set command when a disk label is not found
- libparted-fs-resize: Prevent crash resizing FAT16 file systems.
- libparted-fs-resize: Prevent crash resizing FAT16 file systems.
- If the user specifies start/end of the partition as cylinders
and a cylinder has a size which is power of 2, then such address
