2013-03-11fdisk: use libfdisk label->changedKarel Zak1-46/+27
The patch is huge because it's necessary to add a pointer context to all read_<foo> functions. Signed-off-by: Karel Zak <kzak@redhat.com>

2012-11-30fdisk: api: move disklabel type to cxtDavidlohr Bueso1-94/+97
Get rid of it as a global variable as it belongs in the context. To compare a disklabel on the device, the fdisk_dev_is_disklabel() function is introduced. Also, to avoid naming issues, the fdisk_labeltype members where renamed to FDISK_DISKLABEL_<type>. Signed-off-by: Davidlohr Bueso <dave@gnu.org>

2012-11-02gpt: create empty disklabelsDavidlohr Bueso1-0/+4
This patch enables creating a new, empty, GPT disklabel from either an empty disk or one that already has a disklabel. For this purpose, a 'g' option is added to the main menu and is visible to all labels. Here's an example for a scsi_debug device (/dev/sdb): ... Device does not contain a recognized partition table Building a new DOS disklabel with disk identifier 0x20a614c8. 3696: fdisk: CONTEXT: zeroize in-memory first sector buffer Command (m for help): g 3696: fdisk: LABEL: changing to gpt label 3696: fdisk: CONTEXT: zeroize in-memory first sector buffer 3696: fdisk: LABEL: created new empty GPT disklabel (GUID: D4EA0706-F011-46DC-B7DE-6A72C7090AF8) Command (m for help): w The partition table has been altered! ...

2012-10-18fdisk: fix segfault when printing gpt raw dataDavidlohr Bueso1-1/+2
Signed-off-by: Davidlohr Bueso <dave@gnu.org>
2012-10-18fdisk: api: propagate partition deletion to usersDavidlohr Bueso1-2/+4
The generic fdisk_delete_partition() function returns 0 when a partition is correctly deleted, otherwise it's corresponding error (negative values). This, however, does not include problems that can occur in actual label specific contexts, so we need to propagate the corresponding return code, back to the user visible api. Signed-off-by: Davidlohr Bueso <dave@gnu.org>
2012-09-27fdisk: add GPT supportDavidlohr Bueso1-19/+14
This patch allows fdisk to handle GUID partition tables, based on the latest UEFI specifications version 2.3.1, from June 27th, 2012. The following operations are supported: - Probing (detects both protective and hybrid MBRs) - Writing to disk - Listing used partitions - Adding partitions - Deleting partitions - Data integrity verifications (for both headers and partitions). A few considerations: - Currently we do not fix invalid primary headers -- we just abort! - Header checksums are updated upon every change (ie: add/delete partitions), this allows us to mathematically verify the changes on-the-fly, and not only when writing to disk, like most other related tools do. - We are extremly picky when writing to disk, any error aborts the opeartion. - When creating a new partition, the following GUIDs are available: http://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs For test cases, the gpt.img from libblkid tests, scsi_debug and my own hard drive (/dev/sda) were used. For the image, all operations were tested successfully, and for /dev/sda all except write, which was not tested - hey, I'm not suicidal!
