* libfdisk: (script) support shortcuts in the type= fieldKarel Zak2019-08-081-2/+7
| | | | | | | | | | | | | | | | | | | | The unnamed-field format supports partition type shortcuts: ",1MiB,L' but for named-field format it requires full type: (mbr) "size=1MiB,type=83" (gpt) "size=1MiB,type=0FC63DAF-8483-4772-8E79-3D69D8477DE4" This patch implements type shortcuts also for named-field format: "size=1MiB,type=L" to make it more user-friendly and unified.

* libfdisk: improve partition copy on resizeKarel Zak2019-07-221-0/+6
| | | | | | | | It seems pretty fragile to copy also reference counting and reference to table list. Addresses: https://github.com/karelzak/util-linux/pull/822 Signed-off-by: Karel Zak <kzak@redhat.com>
* libfdisk: Fix double free of *_chs strings in fdisk_partitionVojtech Trefny2019-07-191-0/+4
| | | | | | | __copy_partition doesn't duplicate these strings which leads to occasional double free. Signed-off-by: Vojtech Trefny <vtrefny@redhat.com>
* libfdisk: don't use NTFS as MBRKarel Zak2019-07-171-1/+3

* libfdisk: don't use FAT as MBRKarel Zak2019-07-172-5/+15
| | | | | | | | | 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.

| | | | | | | | | | | | This small change improves possibility to modify by script described PT and use script API in another tools as primary way to create partitions. All you need is to compose script by fdisk_script_set_header() and fdisk_script_set_table() and than apply by fdisk_apply_script().

| | | | | | | | | | The self_pte() can return NULL if partitions array is not large enough, but that should also be impossible and definitely a bug. libfdisk/src/dos.c:984:8: warning: potential null pointer dereference [-Wnull-dereference] libfdisk/src/dos.c:1031:8: warning: potential null pointer dereference [-Wnull-dereference] Signed-off-by: Sami Kerola <kerolasa@iki.fi>

| | | | | | | | Let's keep compilers and static analyzers happy. The idea is to use memcpy() to copy from buffer to variable and use all label as unsigned char rather than vectorize by unsigned short. Signed-off-by: Karel Zak <kzak@redhat.com>

* libfdisk: (dos) rewrite fist/last free sector functionsKarel Zak2019-02-251-106/+169
| | | | | | | | | | | | | | The current code uses first[] and last[] arrays to specify partition ranges. This is unnecessary as we already have all in memory. The current code offers in first and last sector dialogs ranges without care about already used areas.

| | | | | | | | | The current code counts only partition sizes when it counts possible space, but we have gaps between the partitions. It seems better to count all based on offsets rather than sizes.

* libfdisk: accept grain script headerKarel Zak2018-09-122-1/+24
| | | | | | | | | | | | The "grain" variable is used to calculate partitions alignment. The default is 1MiB (or minimal I/O size). The libfdisk provides API to overwrite this default, but this feature has been nowhere accessible for end-user. This patch support for "grain: <size>" in libfdisk scripts.

* libfdisk: Fix multipath partition seperators for user-friendly namesKyleMahlkuch2018-07-041-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | The current code assumes "-part" is the only partition sepereator but this is not true for some distros. For example in Ubuntu 18.04 fdisk does not print the correct names for mpatha: ~# ls -l /dev/mapper/mpatha* lrwxrwxrwx 1 root root 7 Feb 1 04:39 /dev/mapper/mpatha -> ../dm-0 lrwxrwxrwx 1 root root 7 Feb 1 04:38 /dev/mapper/mpatha1 -> ../dm-4 lrwxrwxrwx 1 root root 7 Feb 1 04:38 /dev/mapper/mpatha2 -> ../dm-5 lrwxrwxrwx 1 root root 7 Feb 1 04:38 /dev/mapper/mpatha3 -> ../dm-6 ~# fdisk -l /dev/mapper/mpatha Device Boot Start End Sectors Size Id Type /dev/mapper/mpatha-part1 2048 419432447 419430400 200G 83 Linux /dev/mapper/mpatha-part2 419432448 838862847 419430400 200G 83 Linux /dev/mapper/mpatha-part3 838862848 1258291199 419428352 200G 83 Linux Instead of assuming a partition seperator of "-part" this patch uses access to check the file system for a partition seperator of "p" or the absense of a partition seperator. If neither of these work the patch defaults to "-part" like we had before this patch.
