* libfdisk: (gpt) be more careful with 64bit constantsKarel Zak2016-06-211-29/+27Star
| | | | | | | | It's probably more robust (and readable) to be explicit when we count with constant and 64bit numbers. Addresses: http://bugzilla.redhat.com/show_bug.cgi?id=1344482 Signed-off-by: Karel Zak <kzak@redhat.com>
* fdisk: Fix typo RequiredPartiton -> RequiredPartitionSebastian Rasmussen2016-05-311-1/+6
| | | | | | | | This typo fix is backwards compatible in that fdisk will accept both the GPT attribute RequiredPartition and RequiredPartiton with the typo. Update documentation and tests to all use the new attribute name. Signed-off-by: Sebastian Rasmussen <sebras@gmail.com>

| | | | Adds a header option to alter the GPT table length
* libfdisk: Add support for altering GPT sizeSassan Panahinejad2016-05-183-0/+102
| | | | | | | | | | | | | | | | | | | | | This is useful in two situations: 1. More than 128 partitions are required. Or 2. The partition table must be restricted in size, such as when a system expects to find a bootloader at a location that would otherwise overlap the partition table. The gdisk partitioner supports this feature. libfdisk is already capable of reading and writing partition tables of any size, but previously could only create ones of 128 entries and could not resize. This change should be fairly safe, as it has no effect unless explicitly activated. Signed-off-by: Karel Zak <kzak@redhat.com>

* libfdisk: use fdisk_add_partition() for unused partnoKarel Zak2016-05-101-0/+5
| | | | | | | | | | | | For example: sfdisk -N <parno> may address unused partition. In this case we need to redirect from fdisk_set_partition() to fdisk_add_partition() and follow default setting (used all free space). Signed-off-by: Karel Zak <kzak@redhat.com>
* libfdisk: add fdisk_wipe_partition()Karel Zak2016-05-0410-50/+324
| | | | | | | | | | | | | | | | | | | Now libfdisk provides functionality wipe disk device only ([s]fdisk option --wipe). This patch allows to probe for filesystems/RAIDs on newly created partitions. It means we can remove signatures before the partition node (device) is created. This reduces udev events and it's unnecessary to call wipefs for all partitions. For example sfdisk --wipe=always --wipe-partitions=always /dev/sda <<< ... EOF is a elegant way how to create new disk layout without any obsolete filesystems/RAIDs.

| | | | | | | | | | | | Linux/glibc's qsort_r(3) has differently ordered arguments than BSD implementations. For now we undef that quick and dirty. The real fix would be to make configure check for qsort_r more carefully (AC_CHECK_FUNCS with AC_LANG_WERROR).

* | libfdisk: add API to control signatures wipingKarel Zak2016-02-186-15/+113
|/ | | | | | | | | | | | | | | | | Now libfdisk warns if another filesystem/RAID/PT signature is detected on the device. It seems better and user-friendly to make it possible to wipe the signatures when we write a new disk label to the device. This patch adds to the library API fdisk_enable_wipe() fdisk_has_wipe() fdisk_get_collision() to control this new feature. The device modification is done by libblkid (the same we use in some mkfs-like utils). Signed-off-by: Karel Zak <kzak@redhat.com>
