* dm raid1: add is_remote_recovering hook for clustersJonathan Brassow2009-04-02
| | | | | | | | | | | | | | | | The logging API needs an extra function to make cluster mirroring possible. This new function allows us to check whether a mirror region is being recovered on another machine in the cluster. This helps us prevent simultaneous recovery I/O and process I/O to the same locations on disk. Cluster-aware log modules will implement this function. Single machine log modules will not. So, there is no performance penalty for single machine mirrors.

* dm table: fix upgrade mode raceAlasdair G Kergon2009-04-02
| | | | | | | | | | | | | | upgrade_mode() sets bdev to NULL temporarily, and does not have any locking to exclude anything from seeing that NULL. In dm_table_any_congested() bdev_get_queue() can dereference that NULL and cause a reported oops. Fix this by not changing that field during the mode upgrade.

* dm target: use module refcount directlyCheng Renquan2009-04-02
| | | | | | | | | | | | | | | | The tt_internal's 'use' field is superfluous: the module's refcount can do the work properly. An acceptable side-effect is that this increases the reference counts reported by 'lsmod'. Remove the superfluous test when removing a target module.

* dm snapshot: avoid having two exceptions for the same chunkMikulas Patocka2009-04-02
| | | | | | | | | | | | | | | | | | | | | | We need to check if the exception was completed after dropping the lock. After regaining the lock, __find_pending_exception checks if the exception was already placed into &s->pending hash. But we don't check if the exception was already completed and placed into &s->complete hash. If the process waiting in alloc_pending_exception was delayed at this point because of a scheduling latency and the exception was meanwhile completed, we'd miss that and allocate another pending exception for already completed chunk. It would lead to a situation where two records for the same chunk exist and potential data corruption because multiple snapshot I/Os to the affected chunk could be redirected to different locations in the snapshot.

* dm io: make sync_io uninterruptibleMikulas Patocka2009-04-02
| | | | | | | | | | | | | | | | | | | | If someone sends signal to a process performing synchronous dm-io call, the kernel may crash. The function sync_io attempts to exit with -EINTR if it has pending signal, however the structure "io" is allocated on stack, so already submitted io requests end up touching unallocated stack space and corrupting kernel memory. sync_io sets its state to TASK_UNINTERRUPTIBLE, so the signal can't break out of io_schedule() --- however, if the signal was pending before sync_io entered while (1) loop, the corruption of kernel memory will happen. There is no way to cancel in-progress IOs, so the best solution is to ignore signals at this point.

* dm raid1: switch read_record from kmalloc to slab to save memoryMikulas Patocka2009-04-02
| | | | | | | | | | | | | | | | | | With my previous patch to save bi_io_vec, the size of dm_raid1_read_record is significantly increased (the vector list takes 3072 bytes on 32-bit machines and 4096 bytes on 64-bit machines). The structure dm_raid1_read_record used to be allocated with kmalloc, but kmalloc aligns the size on the next power-of-two so an object slightly greater than 4096 will allocate 8192 bytes of memory and half of that memory will be wasted. This patch turns kmalloc into a slab cache which doesn't have this padding so it will reduce the memory consumed.

* dm: preserve bi_io_vec when resubmitting biosMikulas Patocka2009-04-02
| | | | | | | | | | | | | | | | | Device mapper saves and restores various fields in the bio, but it doesn't save bi_io_vec. If the device driver modifies this after a partially successful request, dm-raid1 and dm-multipath may attempt to resubmit a bio that has bi_size inconsistent with the size of vector. To make requests resubmittable in dm-raid1 and dm-multipath, we must save and restore the bio vector as well. To reduce the memory overhead involved in this, we do not save the pages in a vector and use a 16-bit field size if the page size is less than 65536.
