intel partition map: implement changing the active partition

Implement the needed parts in both the userland add-on (loaded in
DriveSetup) and the kernel side one (used by disk system manager in the
kernel).

This allows changing the active partition in DriveSetup.

Intel Partition Table: Remove dummy atomic_add.

This dummy was intended for boot code, however, atomic_add seems to be
already properly defined in boot code.

Signed-off-by: Jérôme Duval <jerome.duval@gmail.com>

64-bit compilation fixes for write_overlay and intel partitioning system modules.

* Added optional partition_module_info::uninitialize() hook. It is supposed to
destroy the partitioning system's on-disk structure.
* Adjusted the existing partitioning system implementations accordingly.
Actually implemented the hook for the intel partitioning system.
* Added Uninitialize() method to KDiskSystem and KPartitioningSystem. The latter
implements the method calling the new module hook.
* _user_uninitialize_partition(): Also let the disk system uninitialize the
on-disk structure.

This fixes the failure to initialize a disk device with BFS, when it contains a
valid partition map with at least one partition.

specify the path).
* Minor cleanup.

* Removed hard coded sector size.

Added offset and size parameters to create_child_partition() and
KPartition::CreateChild(). CreateChild() calls AddChild(), which publishes
the new partition, though at that point offset and size were not set, so that
the published devices would not be usable.

* Removed SECTOR_SIZE in the read-only part of the intel partition scanner;
however, it's still used in the write part.
* Made the read-only code block size agnostic. Only tested with an Apple
iPod so far, and it recognizes its partition fine now. Next test on real
hardware.
* Cleanup.

Disabled support for nested partition maps for the time being. Since
we're quite lenient parsing the partition descriptors, we recognized
pretty much any partition that by accident has a PTS signature and that
no other disk system supports. Should fix bug #2668.

If the intel partitioning system doesn't detect any children and is not
directly on a device (i.e. has a parent), then don't indicate that we want to
support it at all, but just return -1. Most probably it is actually a
filesystem and not a partition. Indicating that we might support it a bit
could lead to the situation that the partition was associated with the intel
partitioning system in the end because the module for the actually present
filesystem wasn't yet loaded in the first initial device scan (during early
boot when looking for the boot partition).
The later rescan wouldn't touch that partition anymore as it was already
(wrongly) associated with the intel partitioning system, therefore leading to
unrecognized partitions as seen in bug #2424. By not pretending to support the
partition when we most probably don't, a later rescan that has all filesystems
available therefore has a chance of identifying that partition correctly.

* Added BDiskSystem::ShortName() and everything needed to get it there.
* Added BDiskDeviceRoster::GetDiskSystem() method, that can get a disk system
by short/pretty/module name - since they should all be unique, I put them
in a single namespace, please complain if you don't like that :-)
* Cleaned up DiskSystem.h and DiskDeviceRoster.h according to the updated
header guidelines.
* Renamed ntfs pretty name from "ntfs File System" to "Windows NT File System".

* The shadow_changed() FS and partitioning system hooks take an
additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
the kernel, since it is no input parameter. It also copies back the
actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
is returned when the buffer was too small, but then the count must be
returned too.
* Fixed several instances of syscall implementations that unloaded a disk
system, although they didn't load it in the first place. This screwed
up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
event.
* Intel partitioning module:
- The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
now, if the supplied buffer is too small.
- Implemented a part of pm_shadow_changed(), which creates and updates
the PartitionMap, so that the validate_*() hooks have a chance to
work at all.

* Added the partition size as parameter to the file and partitioning
system initialize() hooks. It's often the only info about the
partition one needs and thus locking the partition just to get it is
no longer necessary.
* intel partitioning system:
- Removed passing around block sizes. We require 512 byte sectors
anyway. In fact using the parent partition's block size was even
wrong.
- Simplified writing the partition map sector.
- Simplified and corrected the partition map initialization.
- We don't fail identifying a partition anymore, if the partition map
contains no partitions. We would never identify a freshly
initialized partition map before.
- Made pm_identify() more intelligent: It determines the priority to
return depending on whether the partition is the device itself and
whether we have recognized child partitions.

content name are supported.
* Added file_system_module_info::flags (analogously to
partition_module_info::flags) which indicate which disk device
features the FS supports.
* Replaced the
file_system_module_info/partition_module_info::supports_*()
hooks by a get_supported_operations() hook and for partitioning
systems additionally a get_supported_child_operations() hook.
* Updated file and partitioning systems accordingly.
* Updated fs_shell accordingly.
* Updated the DDM accordingly. The syscall interface remains unchanged,
though.
* _user_supports_initializing_partition() also checks whether the parent
partitioning system is content now.

I just realized I never commited this. This enables Haiku to boot from a logical partition in an extended partition that used to be a BFS partition and has enough of the old super block left for BFS to think it's a valid BFS partition... fix found together with Ingo Weinhold

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15629 a95241bf-73f2-0310-859d-f6bbb57e9c96

* More debug output.
* We apparently cannot use constants like kPartitionTypeIntelExtended
in static array initializers in the kernel.
* Fixed misunderstanding between Axel (boot loader) and me (Intel
partitioning system module) how to deal with the cookie the
identify() hook returns. We switch to a someone cleaner method by
always invoking free_identify_cookie() for it, even if it were passed
to scan(). Since we want to keep the cookie, we add a reference
counter to it.
This should fix a couple of issues with recognizing the boot partition.

This fixes the intel/apple/amiga partitioning modules.
String references, const or not, require the static object to be initialized
by a constructor; it will be put into the BSS region.
Now, kernel modules are not linked against crtbegin.o, and the kernel does
not call any init functions on the module.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4128 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added ShadowPartitionChanged() to KDiskSystem and respective hooks
to the module interfaces. So the disk system will be informed, when a
shadow partition has changed and it is allowed to do necessary
adjustions (e.g. adjusting the cookie, the parameters, or on
partitioning system initialization even creating special child
partitions (apple partitioning system)).
* Added `int32 *index' parameter to ValidateCreateChild(). So the
partitioning system can report at which index the new child shall be
inserted.

Should have waited a few more minutes... Renamed the methods {B,K}Partition::Is{Mountable,Partitionable}() to Contains{File,Partitioning}System(). Similar change for the respective flags (B_PARTITION_{MOUNTABLE,PARTITIONABLE}).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3899 a95241bf-73f2-0310-859d-f6bbb57e9c96

ep_scan_partition(): Removed erroneous check for cookie (it's unused here), and fixed child index counting.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3511 a95241bf-73f2-0310-859d-f6bbb57e9c96

Ported the intel partitioning system module to the new interface

64-bit compilation fixes for write_overlay and intel partitioning system modules.

* Added optional partition_module_info::uninitialize() hook. It is supposed to
destroy the partitioning system's on-disk structure.
* Adjusted the existing partitioning system implementations accordingly.
Actually implemented the hook for the intel partitioning system.
* Added Uninitialize() method to KDiskSystem and KPartitioningSystem. The latter
implements the method calling the new module hook.
* _user_uninitialize_partition(): Also let the disk system uninitialize the
on-disk structure.

This fixes the failure to initialize a disk device with BFS, when it contains a
valid partition map with at least one partition.

Added offset and size parameters to create_child_partition() and
KPartition::CreateChild(). CreateChild() calls AddChild(), which publishes
the new partition, though at that point offset and size were not set, so that
the published devices would not be usable.

If the intel partitioning system doesn't detect any children and is not
directly on a device (i.e. has a parent), then don't indicate that we want to
support it at all, but just return -1. Most probably it is actually a
filesystem and not a partition. Indicating that we might support it a bit
could lead to the situation that the partition was associated with the intel
partitioning system in the end because the module for the actually present
filesystem wasn't yet loaded in the first initial device scan (during early
boot when looking for the boot partition).
The later rescan wouldn't touch that partition anymore as it was already
(wrongly) associated with the intel partitioning system, therefore leading to
unrecognized partitions as seen in bug #2424. By not pretending to support the
partition when we most probably don't, a later rescan that has all filesystems
available therefore has a chance of identifying that partition correctly.

* Added BDiskDeviceRoster::GetDiskSystem() method, that can get a disk system

* Cleaned up DiskSystem.h and DiskDeviceRoster.h according to the updated

* Renamed ntfs pretty name from "ntfs File System" to "Windows NT File System".


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25414 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The shadow_changed() FS and partitioning system hooks take an
additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
the kernel, since it is no input parameter. It also copies back the
actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
is returned when the buffer was too small, but then the count must be
returned too.
* Fixed several instances of syscall implementations that unloaded a disk
system, although they didn't load it in the first place. This screwed
up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
event.
* Intel partitioning module:
- The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
now, if the supplied buffer is too small.
- Implemented a part of pm_shadow_changed(), which creates and updates
the PartitionMap, so that the validate_*() hooks have a chance to
work at all.

- Simplified and corrected the partition map initialization.
- We don't fail identifying a partition anymore, if the partition map

* Turned on debugging in the Intel partitioning system add-on, and the partition
stuff of the boot loader to help with bug #238.
* Minor cleanup (added license headers, fixed debug output)

I just realized I never commited this. This enables Haiku to boot from a logical partition in an extended partition that used to be a BFS partition and has enough of the old super block left for BFS to think it's a valid BFS partition... fix found together with Ingo Weinhold

* More debug output.
* We apparently cannot use constants like kPartitionTypeIntelExtended
in static array initializers in the kernel.
* Fixed misunderstanding between Axel (boot loader) and me (Intel
partitioning system module) how to deal with the cookie the
identify() hook returns. We switch to a someone cleaner method by
always invoking free_identify_cookie() for it, even if it were passed
to scan(). Since we want to keep the cookie, we add a reference
counter to it.
This should fix a couple of issues with recognizing the boot partition.

Refactored a bit -- pulled the partition map parser out. Userland add-on disabled for the time being, due to build problems.

This fixes the intel/apple/amiga partitioning modules.
String references, const or not, require the static object to be initialized
by a constructor; it will be put into the BSS region.
Now, kernel modules are not linked against crtbegin.o, and the kernel does
not call any init functions on the module.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8166 a95241bf-73f2-0310-859d-f6bbb57e9c96

Removed a warning.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4562 a95241bf-73f2-0310-859d-f6bbb57e9c96

Made the module working in the boot loader.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4552 a95241bf-73f2-0310-859d-f6bbb57e9c96

Support for the added partition content size attribute.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4128 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added ShadowPartitionChanged() to KDiskSystem and respective hooks
to the module interfaces. So the disk system will be informed, when a
shadow partition has changed and it is allowed to do necessary
adjustions (e.g. adjusting the cookie, the parameters, or on
partitioning system initialization even creating special child
partitions (apple partitioning system)).
* Added `int32 *index' parameter to ValidateCreateChild(). So the
partitioning system can report at which index the new child shall be
inserted.

The content_type field in partition_data is now set by the system. Implemented querying hooks for resizing a child partition of the partition map.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4048 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some fixes of/changes to the API. Shortened names where possible.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4030 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added SupportsSetting[Content]Parameters() to the KDiskSystem interface and respective functions to the module interface. Some re-ordering of methods/functions for aesthetical reasons. :-)


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4019 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added flags for disk systems.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4009 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added a IsSubSystemFor() method to the KDiskSystem interface and respective calls for the module interfaces.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3996 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some changes to/fixes of the KDiskSystem interface and the disk system module interface.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3987 a95241bf-73f2-0310-859d-f6bbb57e9c96

Should have waited a few more minutes... Renamed the methods {B,K}Partition::Is{Mountable,Partitionable}() to Contains{File,Partitioning}System(). Similar change for the respective flags (B_PARTITION_{MOUNTABLE,PARTITIONABLE}).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3899 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed handling of partition and device flags and statuses.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3898 a95241bf-73f2-0310-859d-f6bbb57e9c96

Small fixes. Make use of the types of types defined in <DiskDeviceTypes.h>.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3613 a95241bf-73f2-0310-859d-f6bbb57e9c96

ep_scan_partition(): Removed erroneous check for cookie (it's unused here), and fixed child index counting.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3511 a95241bf-73f2-0310-859d-f6bbb57e9c96

Ported the intel partitioning system module to the new interface
(disk device manager) and moved it to a nicer place.
First tests look good, though my hard disk structure doesn't even
have extended partitions. Going to install Linux now...
