2013-03-11libfdisk: split label and label operationsKarel Zak7-82/+277
Changes: - fdisk_label is a private label driver struct - generic header of the fdisk_label points to fdisk_label_operations - the private fdisk_label stuff is always allocated for all drivers during fdisk_context initialization - context->labels[] contains pointers to all supported labels (drivers) - context->label is a pointer to the currently used label This change allows to: - store label specific global settings (e.g. dos compatible mode, display units, ...) independently on the current label - add label specific function to the API Signed-off-by: Karel Zak <kzak@redhat.com>

Similarly to commit 1f5eb51b79275e32d045fd6718753bf04cde8374 we do not propagate problems when adding partitions to user visible api. Signed-off-by: Davidlohr Bueso <dave@gnu.org>

2012-11-30fdisk: api: move disklabel type to cxtDavidlohr Bueso10-129/+146
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>

2012-11-14fdisk: gpt: check header sizeDavidlohr Bueso1-1/+8
UEFI states that the size of the GPT header must be between 92 and the sector size. Add the check when verifying a valid header. Signed-off-by: Davidlohr Bueso <dave@gnu.org>

2012-11-02gpt: create empty disklabelsDavidlohr Bueso2-6/+200
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! ...

2012-11-02fdisk: gpt: write entire first sectorDavidlohr Bueso1-2/+5
We were writing only 1 byte in LBA0, and GPT requires dealing with an entire sector. This bug wasn't affecting when dealing with already existing devices with GPT as we weren't writing an important part of the first sector, thus leaving it unchanged. Also use write_all() wrapper from all-io.h Acked-by: Petr Uzel <petr.uzel@suse.cz> Signed-off-by: Davidlohr Bueso <dave@gnu.org>

2012-10-18fdisk: api: propagate partition deletion to usersDavidlohr Bueso8-21/+33
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.
