Mike Fleetwood 99ff0c7628 Add PartitionLUKS class and create objects (#760080)
Absolute minimum implementation of a PartitionLUKS class which can be
constructed, polymorphically copied and destroyed.  Contains an
"encrypted" member of type Partition to represent the encrypted file
system within the LUKS format.

Create PartitionLUKS objects instead of base Partition objects when a
LUKS formatted partition is found.  Only the base Partition object
member values have been populated, and the "encrypted" member remains
blank at this point.

Mike Fleetwood 070d734e57 Add busy detection of LUKS mapping (#760080)
Provide a minimal implementation of a luks file system class which only
does busy detection.

NOTE:
For now, read-only LUKS support, a LUKS partition will be busy when a
dm-crypt mapping exists.  Later when read-write LUKS support is added
GParted will need to look at the busy status of the encrypted file
system within the open LUKS partition and map LUKS partition busy status
to encryption being open or closed.

Mike Fleetwood b77a6be76b Add initial loading of LUKS mapping details (#760080)
Load basic details of active Device-mapper encryption mappings from the
kernel.  Use dmsetup active targets.

    # cryptsetup luksFormat /dev/sdb5
    # cryptsetup luksFormat /dev/sdb6
    # cryptsetup luksOpen /dev/sdb6 sdb6_crypt
    # ls -l /dev/mapper/sdb6_crypt /dev/dm-0
    lrwxrwxrwx. 1 root root 7 Nov 15 09:03 /dev/mapper/sdb6_crypt -> ../dm-0
    brw-rw----. 1 root disk 253, 0 Nov 15 09:03 /dev/dm-0
    # ls -l /dev/sdb6
    brw-rw----. 1 root disk 8, 22 Nov 15 09:02 /dev/sdb6
    # dmsetup table --target crypt
    sdb6_crypt: 0 1044480 crypt aes-cbc-essiv:sha256 0000000000000000000000000000000000000000000000000000000000000000 0 8:22 4096

So far just load the mapping name and underlying block device reference
(path or major, minor pair).

Note that all supported kernels appear to report the underlying block
device as major, minor pair in the dmsetup output.  Underlying block
device paths are added to the cache when found during a search to avoid
stat(2) call on subsequent searches for the same path.

Prints debugging to show results, like this:

Mike Fleetwood fa98273445 Create PartitionVector class (#759726)
Just creates PartitionVector class and includes it in partition.h so
that it is built and validated by the compiler.  Not used anywhere yet.

Implementation strategy is to create a PartitionLUKS class derived from
the Partition class.  This implies polymorphism of Partition objects,
which in C++ requires using pointers and references to objects, and not
using objects directly.  (See C++ object slicing).  Later this
PartitionVector class will be modified to use pointers to Partition
objects and act as the owner of the pointed to Partition objects.

Mike Fleetwood 5f02bcf463 Detect Linux SWRaid members by querying mdadm (#756829)
Detection of Linux SWRaid members currently fails in a number of cases:

1)  Arrays which use metadata type 0.90 or 1.0 store the super block at
    the end of the partition.  So file system signatures in at least
    linear and mirrored arrays occur at the same offsets in the
    underlying partitions.  As libparted only recognises file systems
    this is what is detected, rather than an SWRaid member.

    # mdadm -E -s -v
    ARRAY /dev/md/1  level=raid1 metadata=1.0 num-devices=2 UUID=15224a42:c25bbcd9:15db6000:4e5fe53a name=chimney:1
       devices=/dev/sda1,/dev/sdb1
    ...
    # wipefs /dev/sda1
    offset               type
    ----------------------------------------------------------------
    0x438                ext4   [filesystem]
                         LABEL: chimney-boot
                         UUID:  10ab5f7d-7d8a-4171-8b6a-5e973b402501

    0x1fffe000           linux_raid_member   [raid]
                         LABEL: chimney:1
                         UUID:  15224a42-c25b-bcd9-15db-60004e5fe53a

    # parted /dev/sda print
    Model: ATA VBOX HARDDISK (scsi)
    Disk /dev/sda: 34.4GB
    Sector size (logical/physical): 512B/512B
    Partition Table: msdos

    Number  Start   End     Size    Type      File system  Flags
     1      1049kB  538MB   537MB   primary   ext4         boot, raid
    ...

2)  Again with metadata type 0.90 or 1.0 arrays blkid may report the
    contained file system instead of an SWRaid member.  Have a single
    example of this configuration with a mirrored array containing the
    /boot file system.  Blkid reports one member as ext4 and the other as
    SWRaid!

    # blkid | egrep 'sd[ab]1'
    /dev/sda1: UUID="10ab5f7d-7d8a-4171-8b6a-5e973b402501" TYPE="ext4" LABEL="chimney-boot"
    /dev/sdb1: UUID="15224a42-c25b-bcd9-15db-60004e5fe53a" UUID_SUB="0a095e45-9360-1b17-0ad1-1fe369e22b98" LABEL="chimney:1" TYPE="linux_raid_member"

    Bypassing the blkid cache gets the correct result.

    # blkid -c /dev/null /dev/sda1
    /dev/sda1: UUID="15224a42-c25b-bcd9-15db-60004e5fe53a" UUID_SUB="d0460f90-d11a-e80a-ee1c-3d104dae7e5d" LABEL="chimney:1" TYPE="linux_raid_member"

    However this can't be used because if a user has a floppy configured
    in the BIOS but no floppy attached, GParted will wait for minutes as
    the kernel tries to access non-existent hardware on behalf of the
    blkid query.  See commit:
        18f863151c
        Fix long scan problem when BIOS floppy setting incorrect

3)  Old versions of blkid don't recognise SWRaid members at all so always
    report the file system when found.  Occurs with blkid v1.0 on
    RedHat / CentOS 5.

The only way I can see how to fix all these cases is to use the mdadm
command to query the configured arrays.  Then use this information for
first choice when detecting partition content, making the order: SWRaid
members, libparted, blkid and internal.

GParted shell wrapper already creates temporary blank udev rules to
prevent Linux Software RAID arrays being automatically started when
GParted refreshes its device information[1].  However an administrator
could manually stop or start arrays or change their configuration
between refreshes so GParted must load this information every refresh.
On my desktop with 4 internal hard drives and 3 testing Linux Software
RAID arrays, running mdadm adds between 0.20 and 0.30 seconds to the
device refresh time.

Michael Zimmermann 1f5841b4ad Add support for GPT partition names (#741424)
Embedded devices (Android) use GPT partition names to identify
partitions, instead of file system labels.  Add support for viewing and
changing them.

As partition names are used to provide unique identification they are
never copied when copying the contents of one partition to another.

Note that GNU/Linux uses file system labels, UUIDs or device names for
identification during the boot process and afterwards so while partition
names can be used, they are optional and purely for user information.

Only supports detection and creation of f2fs file systems.  Requires
f2fs-tools and a blkid with f2fs support, util-linux > 2.22.2.

f2fs-tools v1.1.0 only supports file system creation.
Currently requires util-linux directly from the git repository as f2fs
support was only committed on 5 Feb 2013 and it has not yet been
released.

Phillip Susi 52a2a9b00a Reduce threading (#685740)
Win_Gparted and Dialog_Progress were creating threads to perform most
functions in the background.  Most of the time, the only reason the
threads blocked was to execute an external command.  The external command
execution has been changed to spawn the command asynchronously and wait
for completion with a nested main loop.  While waiting for completion,
the pipe output is captured via events.  In the future, this will allow
for it to be parsed in real time to obtain progress information.

Those tasks in GParted_Core that still block now spawn a background thread
and wait for it to complete with a nested main loop to avoid hanging the
gui.

Curtis Gedak de99c530d4 Remove SWRaid method as it is no longer needed (#678379)
Active Linux software RAID devices are detected in the
Proc_Partitions_Info method.  Hence the SWRaid method is no longer
required.

Removal of the SWRaid method fixes the problem with the error message:

  Could not stat device /dev/md/0 - No such file or directory

This fixes the problem because we no longer use "mdadm --examine
--scan" in an attempt to detect Linux software RAID devices.  The
mdadm command was returning device names such as /dev/md/0, which are
incorrect for GParted.

NOTE:  With this change, GParted no longer requires the mdadm command
       to detect Linux software RAID devices.

Closes Bug #678379 - Could not stat device /dev/md/0 - No such file or
                     directory

Curtis Gedak 1607d13a06 Added auto detection of Linux software RAID devices
Auto detection of Linux software RAID devices was lost in GParted
0.3.8.  This was because device scanning by the libparted device
call ped_device_probe_all() was replaced with custom code within
GParted to scan /proc/partitions for devices.

The reason the libparted call was replaced was due to a long
scanning problem with ped_device_probe_all(), a non-existent
physical floppy device, and a BIOS setting indicating a floppy
drive existed.  See bug #351753:
