* libfdisk: don't use FAT as MBRKarel Zak2019-07-171-5/+11
| | | | | | | | | The current libfdisk MBR detection is too weak, the result is that it reuses MBR from FAT. The correct behavior is to create a new MBR, wipe first sector (on write) and warn about obsolete FAT superblock.

* libfdisk: add fdisk_disable_dialogs()Karel Zak2017-07-191-0/+34
| | | | | | | | | | | | | | | The default (for historical reasons) is to use dialog driven partitioning. It's possible to avoid dialogs by fdisk_partition template for fdisk_add_partition(). Unfortunately in some case (mostly DOS driver) it's not enough, because we need to distinguish between logical and primary partitions. If we know that dialogs are unwanted then we can default to primary partition, etc. This function simplify semantic of the library for non-interactive programs.

* libfdisk: use BLKPG ioctls to inform kernel about changesKarel Zak2017-07-141-0/+102
| | | | | | | | | | | | | This patch introduces fdisk_reread_changes(). The function is less invasive alternative to fdisk_reread_partition_table(). The new function uses BLKPG ioctls for modified partitions. The another partitions are not affected. This solution allows to successfully use fdisks on disk where some partitions are still use (mounted). For example if you want to resize the last partition on the device.

* libfdisk: fix NLS supportKarel Zak2017-04-251-0/+2
| | | | | | | | | | | | | | | | | | | The current libfdisk code uses gettext() to translate strings. It means it follows the default text domain (as set by textdomain(3) usually in the main program). This is useless for public shared library. We have call private bindtextdomain() and use dgettext() with private domain name to be independent on the main program. For this purpose include/nls.h supports UL_TEXTDOMAIN_EXPLICIT to use dgettext(). Note that libfdisk will continue to use util-linux.po, rather than keep the texts in the separate file. The nls.h has to be included only from fdiskP.h to be sure that nls.h works as expected for the library. Signed-off-by: Karel Zak <kzak@redhat.com>

* libfdisk: change the way how apply user device propertiesKarel Zak2017-01-131-6/+2Star
| | | | | | | | | | | | | | | | The current code calls fdisk_apply_user_device_properties() after label probing, because we want to overwrite label geometry by user settings (e.g. -C -H -S fdisk options). Unfortunately, this way does not work if we need to use a different sector size, because label probing depends on sector size... So, the right way is to apply user setting to the fdisk context before we start to read from device, and overwrite geometry again after label is already read. Fortunately, this shit is necessary only rarely and for SUN and SGI disk labels. Addresses: https://github.com/karelzak/util-linux/issues/396 Signed-off-by: Karel Zak <kzak@redhat.com>

* libfdisk: add fdisk_wipe_partition()Karel Zak2016-05-041-36/+21Star
| | | | | | | | | | | | | | | | | | | 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.

* libfdisk: add API to control signatures wipingKarel Zak2016-02-181-15/+89
| | | | | | | | | | | | | | | | | 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>
