Fix a large number of bzs:

Browse Source 
- Fix Monitor mode sometimes crashes when a resync completes
- Fix missing symlink for mdadm container device when incremental creates
  the array
- Make sure when creating a second array in a container that the second
  array uses all available space since leaving space for a third array
  is invalid
- Validate the number of imsm volumes per controller
- Fix issues with imsm arrays and disks larger than 2TB
- Add support for expanding imsm arrays/containers
- The support for expanding imsm arrays/containers was accepted upstream,
  update to the official patches from there

Subject: [PATCH] Bitmap_offset is a signed number
As the bitmap can be before the superblock, bitmap_offset is signed.
But some of the code didn't honour that :-(

Subject: [PATCH 14/14] FIX: Assembled second array is in read only state
during reshape
When arrays using external metadata are assembled, and one of array
in container is under reshape, second array will remain in read only
state (not auto read only). It is caused by array fact that array
is frozen and mdmon doesn't has opportunity to switch array in r/w mode.
Freezing not reshaped array just after it is being assembled allows mdmon
to enable it for writing.

It is used to apply changes rollback in error case also.
As change (apply and rollback) can be not bi-directional reshape_super()
has to know if current action is metadata change that should be guarded
using metadata restrictions, or this is metadata rollback change
executed due to error occurrence.
In second case change has to be unconditional.

Subject: [PATCH 2/2] Introduce sysfs_set_num_signed() and use it to set
bitmap/offset
mdinfo->bitmap_offset is a signed long and needs to be treated as
such when passed to the kernel.
This resolves the problem with adding internal bitmaps to a 1.0 array.

Subject: [PATCH] Manage: allow --re-add to failed array.
If both "legs" of a RAID1 (or equivalent in RAID10) fail, then one
of the becomes available again it maybe appropriate to re-add the
failed device(s).
So remove the restriction that an array must has 'enough' devices
before being re-added, and if there is no-where to read a superblock
from for matching, then assume the kernel will do necessary checks.

When we can for devices using GET_DISK_INFO we currently
limit to 1024. But some arrays can have more than this.
So raise it to 4096 and make the constant a #define.

Subject: [PATCH 1/3] Relax restrictions on when --add is permitted.
The restriction that --add was not allowed on a device which
looked like a recent member of an array was overly harsh.
The real requirement was to avoid using --add when the array had
failed, and the device being added might contain necessary
information which can only be incorporated by stopping and
re-assembling with --force.
So change the test to reflect the need.

Subject: [PATCH] Remove avail_disks arg from 'enough'.
It can easily be calculated from 'avail' and 'raid_disks', and we
will soon have a case where we don't have it easily available to pass
in.

Subject: [PATCH] Reset bad flag on map update
Map file may miss an entry if bad flag is not cleared on update.
This happens for example when an old entry exists in map that
has no mdstat counterpart and we create a new array with the same devnum.
Newly created array will not appear in map if update doesnt clear bad flag.

Functions retrieving sizes from metadata do not need to check

clear when the MPB_ATTR_2TB_DISK attribute is not set.
Therefore the following fields are cleared on metadata load
when not in use according to attribute:
struct imsm_disk.total_blocks_hi
struct imsm_map.pba_of_lba0_hi
struct imsm_map.blocks_per_member_hi

If there is no name provided for a container by the metadata it is
always appropriate to use the metadata version name. create_mddev

of confusion.
This makes the --incremental code behave the same as the --assemble code.

Raid1/10
Function imsm_num_data_members() returns wrong value for raid 1 and 10.
It returns all data member but it should return number of unique data
members (excluding mirror devices)

Date: Mon, 2 Apr 2012 10:15:03 +1000
Subject: [PATCH 1/7] imsm: avoid overflows for disks over 1TB
Calculating array_blocks using info->size causes error on activation of
volume using disks over 1 TB. unsigned long long size parameter
is used instead.
total_blocks, pba_of_lba0, blocks_per_member and num_data_stripes overflow
when using disks over 2TB.
Part of fillers in metadata is used to contain hi bits of the numbers
that are likely to go over 32 bit limit.
Functions are added to get and set such fields as the hi bits are not
adjacent with low bits in the structures.

Subject: [PATCH 2/3] imsm: fix: rebuild does not continue after reboot
If system is rebooted during rebuild, md driver changes sync_action
from 'recover' to 'idle' (during stopping all md devices).
If mdmon is still running then, it detects the change of sync_action state,
finishes rebuild and writes metadata to disks. After computer's restart
the RAID volume is in Normal state in OROM and rebuild seems to be finished.
After system's start-up RAID volume is in auto-read-only state
and metadata is in Dirty state. Rebuild seems to be finished but it is not.
Data is inconsistent (out-of-sync).
When mdmon detects the change of sync_action from 'recover' to 'idle',
it has to check if rebuild is really finished. Appropriate test was added.
Now mdmon examines each volume's member if it is being rebuilt.

Subject: [PATCH] imsm: fix: thunderdome may drop 2tb attribute
Spare superblock doesn't depend on other spares in container.
When loading container metadata thunderdome
may pick a small disk for the champion. This will result in incorrect
interpretation of sizes of other disks in container when joint superblock
is returned. If any disk in container has the 2TB attribute set, the result
must have it set too.

Subject: [PATCH 3/3] imsm: validate the number of imsm volumes per controller
IMSM OROM limits number of volumes per controller. Volumes
above the limit are blocked in OROM. mdadm should follow OROM limitations
in this area. Therefore we need to count number of volumes on the devices
attached to SATA (ahci driver) or SAS (isci) controller. Adding a new volume
must be blocked if the number of volumes on devices attached to the given
controller is exceeded.

Subject: [PATCH 3/7] simplify calculating array_blocks
no point calling info_to_blocks_per_member when it just returns size*2 for level==1
calc_array_size can be used for all levels

- Fix Monitor mode sometimes crashes when a resync completes
- Fix missing symlink for mdadm container device when incremental creates
the array
- Make sure when creating a second array in a container that the second
array uses all available space since leaving space for a third array
is invalid
- Validate the number of imsm volumes per controller
- Fix issues with imsm arrays and disks larger than 2TB
- Add support for expanding imsm arrays/containers
- The support for expanding imsm arrays/containers was accepted upstream,
update to the official patches from there
- Fix for the issue of --add not being very smart
- Fix an issue causing rebuilds to fail to restart on reboot (data
corrupter level problem)
- Reset the bad flag on map file updates
- Correctly fix failure when trying to add internal bitmap to 1.0 arrays
- Resolves: bz817023 (f17) bz817024 (f17) bz817026 (f17) bz817028 (f17)
- Resolves: bz817029 (f17) bz817032 (f17) bz817038 (f17) bz808774 (f17)
