Mike Fleetwood aea6200d5f Recognise ATARAID members (#75)
PATCHSET OVERVIEW

A user had a Firmware / BIOS / ATARAID array of 2 devices configured as
a RAID 0 (stripe) set.  On top of that was a GPT with the OS partitions.
GParted displays the following errors on initial load and subsequent
refresh:

        Libparted Error
    (-) Invalid argument during seek for read on /dev/sda
                          [ Retry ] [ Cancel ] [ Ignore ]

        Libparted Error
    (-) The backup GPT table is corrupt, but the
        primary appears OK, so that will be used.
                              [  Ok  ] [ Cancel ]

This is an Intel Software RAID array which stores metadata at the end of
each member device, and so the first 128 KiB stripe of the set is stored
in the first 128 KiB of the first member device /dev/sda which includes
the GPT for the whole RAID 0 device.  Hence when libparted reads member
device /dev/sda it finds a GPT describing a block device twice it's
size and in results the above errors when trying to read the backup GPT.

A more dangerous scenario occurs when using 2 devices configured in an
Intel Software RAID 1 (mirrored) set with GPT on top.  On refresh
GParted display this error for both members, /dev/sda and /dev/sdb:

        Libparted Warning
    /!\ Not all of the space available to /dev/sda appears to be used,
        you can fix the GPT to use all of the space (an extra 9554
        blocks) or continue with the current setting?
                                                  [  Fix  ] [ Ignore ]

Selecting [Fix] gets libparted to re-write the backup GPT to the end of
the member device, overwriting the ISW metadata!  Do that twice and both
copies of the metadata are gone!

Worked example of this more dangerous mirrored set case.  Initial setup:

    # dmraid -s
    *** Group superset isw_caffbiaegi
    --> Subset
    name   : isw_caffbiaegi_MyMirror
    size   : 16768000
    stride : 128
    type   : mirror
    status : ok
    subsets: 0
    devs   : 2
    spares : 0

    # dmraid -r
    /dev/sda: isw, "isw_caffbiaegi", GROUP, ok, 16777214 sectors, data@ 0
    /dev/sdb: isw, "isw_caffbiaegi", GROUP, ok, 16777214 sectors, data@ 0

    # wipefs /dev/sda
    offset               type
    ---------------------------------------------
    0x200                gpt   [partition table]
    0x1fffffc00          isw_raid_member   [raid]

Run GParted and click [Fix] on /dev/sda.  Now the first member has gone:

    # dmraid -s
    *** Group superset isw_caffbiaegi
    --> *Inconsistent* Subset
    name   : isw_caffbiaegi_MyMirror
    size   : 16768000
    stride : 128
    type   : mirror
    status : inconsistent
    subsets: 0
    devs   : 1
    spares : 0

    # dmraid -r
    /dev/sdb: isw, "isw_caffbiaegi", GROUP, ok, 16777214 sectors, data@ 0

    # wipefs /dev/sda
    offset               type
    ---------------------------------------------
    0x200                gpt   [partition table]

Click [Fix] on /dev/sdb.  Now all members of the array are gone:

    # dmraid -s
    no raid disks

    # dmraid -r
    no raid disks

    # wipefs /dev/sdb
    offset               type
    ---------------------------------------------
    0x200                gpt   [partition table]

So GParted must not run libparted partition table scanning on the member
devices in ATARAID arrays.  Only on the array device itself.

In terms of the UI GParted must show disks which are ATARAID members as
whole disk devices with ATARAID member content and detect array busy
status to avoid allowing active members from being overwritten while in
use.

THIS COMMIT

Recognise ATARAID member devices and display in GParted as whole device
"ataraid" file systems.  Because they are recognised as whole device
content ("ataraid" file systems) this alone stops GParted running the
libparted partition table scanning and avoids the above errors.

The list of dmraid supported formats is matched by the signatures
recognised by blkid:

            .name           = "via_raid_member",

As they are all types of Firmware / BIOS / ATARAID arrays, report all
members as a single "ataraid" file system type.  (Except for
"linux_raid_member" in the above blkid source listing which is Linux
Software RAID).

Luca Bacci 12f08d38b8 Set the xalign property for Gtk::Labels (!40)
With the same case as from the previous commit, the very long "Mounted
on ..." text is now wrapped, but the text may not be left justified.
Slowly adjust the dialog width and see how the text wrapping is updated
to fit the size adjustment but the text is centred rather than left
justified.

This is because setting the halign property to Gtk::ALIGN_START does not
guarantee left alignment of text for wrapped or ellipsized Gtk::Labels.

Use the xalign property instead.

To set the xalign property there is a method in the GtkMisc (Gtk::Misc)
base class:

  gtk_misc_set_alignment (Gtk::Misc::set_alignment)

However, GtkMisc (Gtk::Misc) was deprecated in Gtk 3.14 (Gtkmm 3.14)
and in Gtk 3.16 (gtkmm 3.16) set_alignment() was replaced with the
introduction of two new methods:

  gtk_label_set_xalign (Gtk::Label::set_xalign)
  gtk_label_set_yalign (Gtk::Label::set_yalign)

Add a check for Gtkmm method Gtk::Label::set_xalign() in configure.ac
and use it when available.

Luca Bacci f252e677d4 Ensure icon sizes (#39)
Some icon themes only provide large icons for stock items.  This can
cause problems like overly large icons appearing in the GParted UI.
Found on Kubuntu 16.04 LTS with default breeze icon theme.

Be compatible with these icon themes by forcing scaling of stock icons
to the requested size.

Icons are used either by Gtk::Image widgets, or Gtk::CellRendererPixbuf
objects for comboboxes/treeviews.  For Gtk::Image widgets we add
Utils::mk_image() that constructs Gtk::Image widgets and then sets the
pixel-size property.  For Gtk::CellRendererPixbuf we add
Utils::mk_pixbuf() that first loads a Gdk::Pixbuf and then scales if
needed.

Mike Fleetwood 69c1537a38 Recognise APFS (Apple File System) (#23)
Just add detection of APFS using GParted's internal magic string
detection.  It just matches 1 byte of the 2 byte object type and the
4 byte magic field found in the super block [1].  See code comment for
more details.

Blkid has just gained recognition of APFS with util-linux v2.33 released
06-Nov-2018 [2].

This will write enough for GParted's simple internal detection to find
APFS:

Mike Fleetwood d3ef32096a Re-assign UFS to be a basic supported file system (!13)
There is no prospect of there being ufs-tools on Linux.  The was a
project which did release ufs-tools version 0.1 in 2004, but has been
inactive since then.
    http://ufs-linux.sourceforge.net/

Copying and moving is now implemented for file systems in the basic
supported category.  Also mounting and unmounting of unsupported file
system and reporting their usage while mounted has been added.  This is
all the support that GParted has ever implemented for UFS.  Therefore
re-assign UFS as a basic supported file system as it looses no
functionality.

Mike Fleetwood f61481f3ae Separate unknown file system type from unsupported actions (!13)
PATCHSET OVERVIEW:

Forum user wanted to be able to move a partition with unknown content:
    Topic: Can't move/rezise partition on android device (unknown format)
    http://gparted-forum.surf4.info/viewtopic.php?id=17742

While GParted isn't going to be able to run any sort of file system
check on the unknown content there isn't any reason why such a partition
can't be copied or moved so long as the partition stays the same size.
GParted can just use it's existing internal block copy routine it uses
for copying and moving most partition content.  This is no different to
a few of the already supported file system types which don't have a
check-repair tool: exfat, f2fs, nilfs2, udf, ufs.

This patchset introduces a third category called basic file system
support to go along with the existing full and unsupported categories.
Basic supported file systems will just use GParted's inbuilt
capabilities to perform actions so they won't need a derived FileSystem
implementation class.  Unknown file systems along with all other
recognised, but otherwise unsupported, file systems will be assigned to
this new basic supported category.

THIS PATCH:

FS_UNKNOWN is used when GParted is unable to identify the contents of a
partition.  FS_UNKNOWN is also used to generate a file system support
set with no supported actions, in the FileSystem::FS::FS() constructor
and in GParted_Core::get_fs().

As support for operations on partitions with unknown content is being
added, the second usage will be confusing or even wrong.
FS( FS_UNKNOWN ) constructs the no supported actions set, yet GParted
will support some actions for the FS_UNKNOWN file system type.
Therefore add FS_UNSUPPORTED for the second usage.

Mike Fleetwood 8dff80edc6 Add ability for small writes to stdin of child processes (#795617)
As discussed in "LUKS password handling, threats and preventative
measures" [1] GParted must be able to pass LUKS passphrases to
cryptsetup via standard input to avoid having to write passwords to the
file system and deal with additional security requirements.  Therefore
add a way to write input into created child processes.  For small
amounts of input, writing up to the pipe buffer capacity won't block
[2].  This is 64K on versions of Linux in any currently supported
distributions.

[1] LUKS password handling, threats and preventative measures
    https://bugzilla.gnome.org/show_bug.cgi?id=627701#c56

    GParted must not become a password manage so it must never save
    LUKS passwords to disk across separate invocations of GParted.
    ...

    GParted should avoid writing a temporary file containing the LUKS
    password as it introduces extra complexity with trying to safely
    handle and erase file content.  Instead GParted must
    programmatically pass the LUKS password via standard input to the
    cryptsetup command.

[2] pipe(7) manual page:

    Pipe capacity
        A pipe has a limited capacity.  If the pipe is full, then a
        write(2) will block or fail, depending on whether the O_NONBLOCK
        flag is set (see below).  ...

        In Linux versions before 2.6.11, the capacity of a pipe was the
        same as the system page size (e.g., 4096 bytes on i386).  Since
        Linux 2.6.11, the pipe capacity is 65536 bytes.

Mike Fleetwood 175d27c55d Rename enum FILESYSTEM to FSType
There are too many different types of things named "filesystem" in the
GParted code with the potential to cause confusion.  Namely:

    std::vector<FS> FILESYSTEMS
                              Vector of file system capabilities.

    class FileSystem          Base class interfacing to file system
                              specific executables for querying and
                              modification.

    enum FILESYSTEM           Symbolic constants representing each file
                              system type.

Many recent written or re-written functions already used a variable
named fstype.  Rename enum FILESYSTEM to enum FSType to clearly
distinguish it from the other things with very similar names.  Only
changing the name of the enumeration, not the name of variables of that
type too because that is a lot more lines of code and those can be
changed when the relevant code is re-written.

2018-01-28 10:09:35 -07:00
Mike Fleetwood 04535c48b3 Create separate file system limits structure and getter method (#787204)
PATCH SET OVERVIEW:

Currently the supported actions of each file system and their size
limits are stored in struct FS objects.  These are created by calling
file system specific derived implementations of
FileSystem::get_filesystem_support().  This happens when GParted is
started or when a when a rescan for supported actions is performed.  The
file system size limits are expressed as a fixed number of bytes.

The maximum UDF file system size is specified in terms of file system
block size units.  Also the file system block size must match the sector
size of the underlying device.  Typically 2K for optical media and 512
bytes or 4K for hard drives.

Therefore GParted can't properly express the true UDF file system size
limits because they depend on the block size of an existing UDF file
system or the sector size of the device for new UDF file systems.  In
fact other file systems such as EXT2/3/4 and XFS actually express their
maximum file system size in terms of numbers of file system blocks but
these tend to always be 4K and don't have to match the sector size of
the underlying device, so fixed byte values tend to suffice.

To update GParted for this, first separate file system size limits from
struct FS into struct FS_Limits and provide new
FileSystem::get_filesystem_limits() method to allow the limits to be
queried independently of the calls to get_filesystem_support().
Second, pass Partition objects and allow derived get_filesystem_limits()
implementations.

THIS PATCH:

Just creates a separate structure storing fixed value file system
minimum and maximum size limits along with getter method
get_filesystem_limits().

After removing "../include/" from the GParted header #includes, just
need to add "-I../include" to the compile command via the AM_CPPFLAGS in
src/Makefile.am.  Now the dependencies on GParted header files are
tracked under a single name (with a single "../include/" prefix).  Now
DialogFeatures.o only depends on a single name to Utils.h:

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.

Renamed from DEV_MAP_PATH to DEV_MAPPER_PATH.  Moved so that the
constant is logically intended for use outside of the DMRaid class.

Also specifically make the string constant have external linkage, rather
than the default internal (static) linkage for constants, so that there
is only one copy of the variable in the program, rather than one copy in
each compilation unit which included DMRaid.h.  Namely DMRaid.cc and
GParted_Core.cc.

Mike Fleetwood 1a4cefb960 Initialise all struct FS members
The struct FS constructor initialised every member *except* filesystem
and busy.  Then in *most* cases after declaring struct FS, assignments
followed like this:
    FS fs;
    fs.filesystem = FS_BTRFS;
    fs.busy       = FS::GPARTED;
But member busy wasn't always initialised.

Add initialisation of members filesystem and busy to the struct FS
constructor.  Specify optional parameter to the constructor to set the
filesystem member, or when left off filesystem is initialised to
FS_UNKNOWN.

Mike Fleetwood 2b57229fc2 Implement shell style exit status decoding (#754684)
Command exit status is a 1 byte value between 0 and 255. [1][2]  However
at the Unix API level the value is encoded as documented in the
waitpid(2) manual page.  This is true for the Glib API too. [3]  This is
why, for example, the comment in ext2::check_repair() reported receiving
undocumented exit status 256.  It was actually receiving exit status 1
encoded as per the waitpid(2) method.

Add shell style exit status decoding [2] to execution of all external
commands.   Return value from Utils::execute_command() and
FileSystem::execute_command() functions are now:
    0 - 125 - Exit status from the command
    126     - Error executing the command
    127     - Command not found
    128+N   - Command terminated by signal N
    255     - Unexpected waitpid(2) condition
Also adjust checking of the returned statuses as necessary.

[1] Advanced Bash-Scripting Guide: Appendix D. Exit Codes With Special
    Meanings
    http://www.linuxtopia.org/online_books/advanced_bash_scripting_guide/exitcodes.html

[2] Quote from the bash(1) manual page:

        EXIT STATUS
            ... Exit statuses fall between 0 and 255, though as
            explained below, the shell may use values above 125
            specially.  ...

            ... When a command terminates on a fatal signal N, bash uses
            the value of 128+N as the exit status.

            If a command is not found, the child process created to
            execute it returns a status of 127.  If a command is found
            but is not executable, the return status is 126.

Mike Fleetwood 0bdc1fef14 Add lookup for Linux kernel names of mountable file systems (#742741)
Function Utils::get_filesystem_kernel_name() returns the name of the
file system as needed for use in the mount command:

Needed because the kernel / mount name is 'hfsplus' where as libparted /
GParted, as reported by Utils::get_filesystem_string(), calls it 'hfs+'.
So far just added debugging when mounting a file system to test the
function works.

Mike Fleetwood b1dc9e69e3 Make partition busy detection method selectable per file system (#723842)
GParted's primary inbuilt busy detection method is "is the partition
mounted?".  A custom method is used for LVM2 PV because its not a
mounted file system.

Make busy detection selectable per file system type.

    .fs.busy = FS::NONE  (default)
        No busy detection.

    .fs.busy = FS::GPARTED
        Use internal GParted method which checks if the partition is
        mounted.

    .fs.busy = FS:EXTERNAL
        Call the file system type's member function is_busy().

LVM2 PV busy detection changes from a special case to just electing to
call the lvm2_pv::is_busy() method.  Linux Software RAID remains a
special case because it's only recognised, but not otherwise supported.

Curtis Gedak 6efa623401 Add optional yalign argument to Utils::mk_label() method
As part of the work on bug 652044 - uses deprecated APIs, selectable
vertical alignment was defaulted to ALIGN_CENTER for all labels.  The
relevant commits can be viewed in comment 26 of said bug report.
https://bugzilla.gnome.org/show_bug.cgi?id=652044#c26

For multi-line labels a vertical ALIGN_CENTER value is not
consistently aesthetically pleasing.  This becomes obvious when a
single-line heading label is paired with a multi-line value label.
To improve the aesthetics, a vertical alignment of ALIGN_TOP is
preferred.

Hence re-add the ability to optionally specify a vertical alignment for
labels.  If a yalign value is not specified a default vertical alignment
of ALIGN_CENTER is used.

This patch to btrfs-progs has been included in the integration

    # mkfs.btrfs /dev/sdb1
    ...
    /dev/sdb1 appears to contain an existing filesystem (btrfs).
    Use the -f option to force overwrite.

With this commit to btrfs-progs on 2013-02-19, mkfs.btrfs checks for
existing file system signatures, including all mirror copies of btrfs
super blocks, before writing to the partition.

    btrfs-progs: require mkfs -f force option to overwrite filesystem or partition table

Make GParted clear all the mirror copies of the btrfs file system super

Sinlu Bes 20006e1f8e Add create_with_label flag to struct FS (#701569)
It was difficult to retrieve whether a filesystem's label can be set on reformat.

The read_label flag can't be used as it decides whether to use the logic in the filesystem class
rather than the fallback in GParted::set_device_partitions, to determine the label of a partition.

The create_with_label flag is NONE for file systems that we cannot format with a
label (or that we cannot format at all).
The value is usually EXTERNAL for file systems that we can format with a label.
