2009-12-10dm snapshot: rename dm_snap_exception to dm_exceptionJon Brassow4-28/+28
The exception structure is not necessarily just a snapshot element (especially after we pull it out of dm-snap.c). Renaming appropriately. Signed-off-by: Jonathan Brassow <jbrassow@redhat.com> Reviewed-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2009-12-10dm snapshot: consolidate insert exception functionsJon Brassow1-12/+4
Consolidate the insert_*exception functions. 'insert_completed_exception' already contains all the logic to handle 'insert_exception' (via check for a hash_shift of 0), so remove redundant function.

2009-12-10dm snapshot: simplify sector_to_chunk expressionMikulas Patocka1-1/+1
Removed unnecessary 'and' masking: The right shift discards the lower bits so there is no need to clear them. (A later patch needs this change to support a 32-bit chunk_mask.)

2009-12-10dm ioctl: prefer strlcpy over strncpyRoel Kluin1-2/+2
strlcpy() will always null terminate the string. The code should already guarantee this as the last bytes are already NULs and the string lengths were restricted before being stored in hc. Removing the '-1' becomes necessary so strlcpy() doesn't lose the last character of a maximum-length string. - agk Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Alasdair G Kergon <agk@redhat.com>

2009-12-10dm raid1: hold all write bios when leg failsMikulas Patocka1-2/+10
Hold all write bios when leg fails and errors are handled When using a userspace daemon such as dmeventd to handle errors, we must delay completing bios until it has done its job. This patch prevents the following race: - primary leg fails - write "1" fail, the write is held, secondary leg is set default - write "2" goes straight to the secondary leg Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Reviewed-by: Takahiro Yasui <tyasui@redhat.com> Tested-by: Takahiro Yasui <tyasui@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2009-12-10dm raid1: hold write bios when errors are handledMikulas Patocka1-31/+32
Hold all write bios when errors are handled. Previously the failures list was used only when handling errors with a userspace daemon such as dmeventd. Now, it is always used for all bios. The regions where some writes failed must be marked as nosync. This can only be done in process context (i.e. in raid1 workqueue), not in the write_callback function. Previously the write would succeed if writing to at least one leg succeeded. This is wrong because data from the failed leg may be replicated to the correct leg. Now, if using a userspace daemon, the write with some failures will be held until the daemon has done its job and reconfigured the array. If not using a daemon, the write still succeeds if at least one leg succeeds. This is bad, but it is consistent with current behavior.

2009-12-10dm log: use flush callback fnMikulas Patocka1-2/+15
Call the flush callback from the log. If flush failed, we have no alternative but to mark the whole log as dirty.

2009-12-10dm log: add flush callback fnMikulas Patocka3-5/+9
Introduce a callback pointer from the log to dm-raid1 layer. Before some region is set as "in-sync", we need to flush hardware cache on all the disks. But the log module doesn't have access to the mirror_set structure. So it will use this callback. So far the callback is unused, it will be used in further patches.

2009-12-10dm log: introduce flush_failed variableMikulas Patocka1-1/+4
Introduce "flush failed" variable. When a flush before clearing a bit in the log fails, we don't know anything about which which regions are in-sync and which not. So we need to set all regions as not-in-sync and set the variable "flush_failed" to prevent setting the in-sync bit in the future. A target reload is the only way to get out of this situation.

Split the variable "touched" into two, "touched_dirtied" and "touched_cleaned", set when some region was dirtied or cleaned. This will be used to optimize flushes. After a transition from "dirty" to "clean" state we don't have flush hardware cache on the log device. After a transition from "clean" to "dirty" the cache must be flushed. Before a transition from "clean" to "dirty" state we don't have to flush all the raid legs. Before a transition from "dirty" to "clean" we must flush all the legs to make sure that they are really in sync.

2009-12-10dm io: remove extra bi_io_vec region hackMikulas Patocka1-34/+55
Remove the hack where we allocate an extra bi_io_vec to store additional private data. This hack prevents us from supporting barriers in dm-raid1 without first making another little block layer change. Instead of doing that, this patch eliminates the bi_io_vec abuse by storing the region number directly in the low bits of bi_private. We need to store two things for each bio, the pointer to the main io structure and, if parallel writes were requested, an index indicating which of these writes this bio belongs to. There can be at most BITS_PER_LONG regions - 32 or 64. The index (region number) was stored in the last (hidden) bio vector and the pointer to struct io was stored in bi_private. This patch now aligns "struct io" on BITS_PER_LONG bytes and stores the region number in the low BITS_PER_LONG bits of bi_private.

2009-12-10dm io: use slab for struct ioMikulas Patocka3-1/+25
Allocate "struct io" from a slab. This patch changes dm-io, so that "struct io" is allocated from a slab cache. It used to be allocated with kmalloc. Allocating from a slab will be needed for the next patch, because it requires a special alignment of "struct io" and kmalloc cannot meet this alignment.

2009-12-10dm crypt: make wipe message also wipe essiv keyMilan Broz1-4/+30
The "wipe key" message is used to wipe the volume key from memory temporarily, for example when suspending to RAM. But the initialisation vector in ESSIV mode is calculated from the hashed volume key, so the wipe message should wipe this IV key too and reinitialise it when the volume key is reinstated. This patch adds an IV wipe method called from a wipe message callback. ESSIV is then reinitialised using the init function added by the last patch.

2009-12-10dm crypt: separate essiv allocation from initialisationMilan Broz1-26/+43
This patch separates the construction of IV from its initialisation. (For ESSIV it is a hash calculation based on volume key.) Constructor code now preallocates hash tfm and salt array and saves it in a private IV structure.

2009-12-10dm snapshot: cope with chunk size larger than originMikulas Patocka1-0/+2
Under some special conditions the snapshot hash_size is calculated as zero. This patch instead sets a minimum value of 64, the same as for the pending exception table. rounddown_pow_of_two(0) is an undefined operation (it expands to shift by -1). init_exception_table with an argument of 0 would fail with -ENOMEM. The way to trigger the problem is to create a snapshot with a chunk size that is larger than the origin device.

2009-12-10dm: avoid _hash_lock deadlockMikulas Patocka2-9/+17
Fix a reported deadlock if there are still unprocessed multipath events on a device that is being removed. _hash_lock is held during dev_remove while trying to send the outstanding events. Sending the events requests the _hash_lock again in dm_copy_name_and_uuid. This patch introduces a separate lock around regions that modify the link to the hash table (dm_set_mdptr) or the name or uuid so that dm_copy_name_and_uuid no longer needs _hash_lock. Additionally, dm_copy_name_and_uuid can only be called if md exists so we can drop the dm_get() and dm_put() which can lead to a BUG() while md is being freed. The deadlock: #0 [ffff8106298dfb48] schedule at ffffffff80063035 #1 [ffff8106298dfc20] __down_read at ffffffff8006475d #2 [ffff8106298dfc60] dm_copy_name_and_uuid at ffffffff8824f740 #3 [ffff8106298dfc90] dm_send_uevents at ffffffff88252685 #4 [ffff8106298dfcd0] event_callback at ffffffff8824c678 #5 [ffff8106298dfd00] dm_table_event at ffffffff8824dd01 #6 [ffff8106298dfd10] __hash_remove at ffffffff882507ad #7 [ffff8106298dfd30] dev_remove at ffffffff88250865 #8 [ffff8106298dfd60] ctl_ioctl at ffffffff88250d80 #9 [ffff8106298dfee0] do_ioctl at ffffffff800418c4 #10 [ffff8106298dff00] vfs_ioctl at ffffffff8002fab9 #11 [ffff8106298dff40] sys_ioctl at ffffffff8004bdaf #12 [ffff8106298dff80] tracesys at ffffffff8005d28d (via system_call) Cc: stable@kernel.org Reported-by: guy keren <choo@actcom.co.il> Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
