* libfdisk: Detect out-of-space when adding new primary partitionIan Wienand2015-10-091-1/+4
| | | | | | | | | | | | | | | | | | | | | | I got a bit confused with the interaction below: Command (m for help): p Disk /dev/sda: 41 GiB, 43965677568 bytes, 85870464 sectors ... Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 1026047 1024000 500M 83 Linux /dev/sda2 1026048 85868543 84842496 40.5G 8e Linux LVM Command (m for help): n To create more partitions, first replace a primary with an extended partition. I knew I should have had two primary partitions available, but I did not notice that the disk was seen as full (I was trying to grow it) This change detects available primary partitions, and if so indicates we are out of space, rather than out of partitions.

* lib/crc32: don't require to modify GPT headerKarel Zak2015-09-241-46/+35Star
| | | | | | | | | | This patch introduces smart crc32 function that is able to exclude specified. The advantage is that we does not have to modify GPT header (set the current in-header crc field to zero) when we count crc32. This allows to keep GPT header in read-only buffers and simplify code.

* libfdisk: ignore misaligned optimal I/O sizeKarel Zak2015-06-181-3/+12
| | | | | | | | | | | | | | | | | | For example: # modprobe scsi_debug dev_size_mb=1000 opt_blks=65535 physblk_exp=3 creates a disk with: Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 33553920 bytes where 33553920 % 4096 != 0, it means that use Optimal I/O size to align partition results that partition is not aligned to physical sector boundary.

| | | | | | | | | | | | | | | | | | | | | | | | | | * removes list() label operation from internal API The list() has been based on fdisk_info() it was useless for anything else than print on stdout... * add a new get_item() label operation and fdisk_get_disklabel_item() public API The new API provides abstract and pretty simple way how to get label specific disk label information, for example fdisk_get_disklabel_item(cxt, GPT_LABELITEM_ENTRIESLBA, &iterm); return LBA of the array with GPT entries. Note that this patch does not implement public functions to get data from the @item object. * removes get_id() label operation -- it's subset of the new get_item() * the new internal API is also used to implement backwardly compatible fdisk_list_disklabel() and fdisk_get_disklabel_id() Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's create a disk with 33553920 bytes optimal I/O size: # modprobe scsi_debug dev_size_mb=1000 opt_blks=65535 and try to create partition: echo -e 'n\n\n\n\n+512M\np\nq\n' | fdisk /dev/sdc old version: Device Boot Start End Sectors Size Id Type /dev/sdc1 65535 1114110 1048576 512M 83 Linux The next partition will be expected on sector 1114110 + 1, but it's not aligned to optimal I/O: ((1114110 + 1) * 512) % 33553920 = 8192 fixed version: Device Boot Start End Sectors Size Id Type /dev/sdc1 65535 1114094 1048560 512M 83 Linux ((1114094 + 1) * 512) % 33553920 = 0 Note that the same problem with alignment calculation has been fixed in Linux kernel by commit b8839b8c55f3fdd60dc36abcda7e0266aff7985c (Oct 2014). The patch also improves fdisk_align_lba_in_range() to not align sizes smaller than grain (default 1MiB) to make it possible to create really small partitions.

| | | | | | | | | | It is impossible to predict /dev/dm-N partition names. Use predictable and better readable /dev/mapper names instead. [kzak@redhat.com: - remove if-before-free] Signed-off-by: Stanislav Brabec <sbrabec@suse.cz> Signed-off-by: Karel Zak <kzak@redhat.com>
* Use correct partition names for /dev/mapperStanislav Brabec2015-05-261-2/+4
| | | | | | | | | | | | | | The default configuration of multipath-tools appends "-partN" to partition nodes. Follow this conventions and do the same. It fixes for example fdisk -l /dev/mapper/name_of_the_device. Note that the current implementation only partially fixes the problem. It does not reflect any udev configuration changes, as udev does not provide any function to return names of future (or current) partitions of a particular device. It also does not fix fdisk -l /dev/dm-0. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>

* libfdisk: (gpt) fix attributes endianessRuediger Meier2015-05-111-4/+4
| | | | | | | | | | | The new libfdisk/gpt test (4a4a0927) discovered that we read and write partition attributes wrongly on BE systems. Our temporarily used char[8] bits are always LE and do not need to be converted. CC: Michael Marineau <michael.marineau@coreos.com> Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* libfdisk: (gpt) add API for raw partition attributesMichael Marineau2015-05-055-0/+138
| | | | | | | | | | | | | | | | | The existing APIs can only toggle individual bits or get and set bits in a complex text representation, making it impractical to use libfdisk for manipulating the GPT partition attribute field in more complex ways such as updating a value that is multiple bits wide. For example priority based partition selection originally designed for ChromeOS includes two integer values that are 4-bits wide. http://www.chromium.org/chromium-os/chromiumos-design-docs/disk-format#TOC-Trusting-the-GPT [kzak@redhat.com: - add new symbols to .sym file and docs - remove unused variables from test program] Signed-off-by: Michael Marineau <michael.marineau@coreos.com> Signed-off-by: Karel Zak <kzak@redhat.com>
* libfdisk: (gpt) fix check for beginning of protective partitionMichael Marineau2015-05-051-7/+7
| | | | | | | | | | Search for the protective partition before attempting to validate that it covers the GPT header. Some hybrid MBRs list partitions out of order. For example, CoreOS images ship with a hybrid MBR that lists the boot partition first and the protective partition second in order to maintain compatibility with old versions of Xen's PV-GRUB.
