* dm: introduce num_flush_requestsMikulas Patocka2009-06-222-0/+50
| | | | | | | | | | | | Introduce num_flush_requests for a target to set to say how many flush instructions (empty barriers) it wants to receive. These are sent by __clone_and_map_empty_barrier with map_info->flush_request going from 0 to (num_flush_requests - 1). Old targets without flush support won't receive any flush requests.

* dm: remove EOPNOTSUPP for barriersMikulas Patocka2009-06-221-1/+1
| | | | | | | | | | | | | If the underlying device doesn't support barriers and dm receives a barrier, it waits until all requests on that device drain so it no longer needs to report -EOPNOTSUPP to the caller. This patch deals with the confusing situation when moving a volume from one physical device to another triggers an EOPNOTSUPP on a volume that didn't report it before.

| | | | | | | | | | | If barrier request was returned with DM_ENDIO_REQUEUE, requeue it in dm_wq_work instead of dec_pending.

* dm: always hold bdev referenceMikulas Patocka2009-06-221-41/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a potential deadlock when creating multiple snapshots by holding a reference to struct block_device for the whole lifecycle of every dm device instead of obtaining it independently at each point it is needed. bdget_disk() was called while the device was being suspended, in dm_suspend(). However there could be other devices already suspended, for example when creating additional snapshots of a device. bdget_disk() can wait for IO and allocate memory resulting in waiting for the already-suspended device - deadlock. This patch changes the code so that it gets the reference to struct block_device when struct mapped_device is allocated and initialized in alloc_dev() where it is always OK to allocate memory or wait for I/O. It drops the reference when it is destroyed in free_dev(). Thus there is no call to bdget_disk() while any device is suspended. Previously unlock_fs() was called only if bdev was held. Now it is called unconditionally, but the superfluous calls are harmless because it returns immediately if the filesystem was not previously frozen. This patch also now allows the device size to be changed in a noflush suspend because the bdev is held. This has no adverse effect.

| | | | | | | | | | | | Rename suspended_bdev to bdev. This patch doesn't change any functionality, just renames the variable. In the next patch, the variable will be used even for non-suspended device. (Pre-requisite for the per-target barrier support patches.)

* dm exception store: fix exstore lookup to be case insensitiveJonathan Brassow2009-06-221-1/+1
| | | | | | | | | | | | When snapshots are created using 'p' instead of 'P' as the exception store type, the device-mapper table loading fails.

* dm: use i_size_readMikulas Patocka2009-06-223-3/+4
| | | | | | | | | | | | | | | Use i_size_read() instead of reading i_size. If someone changes the size of the device simultaneously, i_size_read is guaranteed to return a valid value (either the old one or the new one). i_size can return some intermediate invalid value (on 32-bit computers with 64-bit i_size, the reads to both halves of i_size can be interleaved with updates to i_size, resulting in garbage being returned).

* dm: avoid unsupported spanning of md stripe boundariesMikulas Patocka2009-06-221-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | A bio that has two or more vector entries, size less than or equal to page size, that crosses a stripe boundary of an underlying md device is accepted by device mapper (it conforms to all its limits) but not by the underlying device. The fix is: If device mapper selects the one-page maximum request size, it also needs to set its own q->merge_bvec_fn to reject any bios with multiple vector entries that span more pages. The problem was discovered in the following scenario: * MD - RAID-0 * LV on the top of it (raid1, snapshot or striped with chunk size/stripe larger than RAID-0 stripe) * one of the logical volumes is exported to xen domU * inside xen domU it is partitioned, the key point is that the partition must be unaligned on page boundary (fdisk normally aligns the partition to 63 sectors which will trigger it) * install the system on the partitioned disk in domU This causes I/O failures in dom0.

* dm mpath: flush keventd queue in destructorMikulas Patocka2009-06-221-0/+1
| | | | | | | | | | | | | | | | | | | | | The commit fe9cf30eb8186ef267d1868dc9f12f2d0f40835a moves dm table event submission from kmultipath queue to kernel kevent queue to avoid a deadlock. There is a possibility of race condition because kevent queue is not flushed in the multipath destructor. The scenario is: - some event happens and is queued to keventd - keventd thread is delayed due to scheuling latency or some other work - multipath device is destroyed - keventd now attempts to process work_struct that is residing in already released memory. The patch flushes the keventd queue in multipath constructor. I've already fixed similar bug in dm-raid1.

* dm raid1: keep retrying alloc if mempool_alloc failedMikulas Patocka2009-06-221-1/+1
| | | | | | | | | | | | | | If the code can't handle allocation failures, use __GFP_NOFAIL so that in case of memory pressure the allocator will retry indefinitely and won't return NULL which would cause a crash in the function. This is still not a correct fix, it may cause a classic deadlock when memory manager waits for I/O being done and I/O waits for some free memory. I/O code shouldn't allocate any memory. But in this case it probably doesn't matter much in practice, people usually do not swap on RAID.

* dm mpath: call activate fn for each path in pg_initChandra Seetharaman2009-06-221-37/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed a problem affecting reinstatement of passive paths. Before we moved the hardware handler from dm to SCSI, it performed a pg_init for a path group and didn't maintain any state about each path in hardware handler code. But in SCSI dh, such state is now maintained, as we want to fail I/O early on a path if it is not the active path. All the hardware handlers have a state now and set to active or some form of inactive. They have prep_fn() which uses this state to fail the I/O without it ever being sent to the device. So in effect when dm-multipath calls scsi_dh_activate(), activate is sent to only one path and the "state" of that path is changed appropriately to "active" while other paths in the same path group are never changed as they never got an "activate". In order make sure all the paths in a path group gets their state set properly when a pg_init happens, we need to call scsi_dh_activate() on all paths in a path group. Doing this at the hardware handler layer is not a good option as we want the multipath layer to define the relationship between path and path groups and not the hardware handler. Attached patch sends an "activate" on each path in a path group when a path group is switched. It also sends an activate when a path is reinstated.

* dm mpath: change attached scsi_dhHannes Reinecke2009-06-221-2/+13
| | | | | | | | | | | | | | | | | | | | When specifying a different hardware handler via multipath features we should be able to override the built-in defaults. The problem here is the hardware table from scsi_dh is compiled in and cannot be changed from userland. The multipath.conf OTOH is purely user-defined and, what's more, the user might have a valid reason for modifying it. (EG EMC Clariion can well be run in PNR mode even though ALUA is active, or the user might want to try ALUA on any as-of-yet unknown devices) So _not_ allowing multipath to override the device handler setting will just add to the confusion and makes error tracking even more difficult.
