2013-07-10dm: add switch targetJim Ramsay
dm-switch is a new target that maps IO to underlying block devices efficiently when there is a large number of fixed-sized address regions but there is no simple pattern to allow for a compact mapping representation such as dm-stripe. Though we have developed this target for a specific storage device, Dell EqualLogic, we have made an effort to keep it as general purpose as possible in the hope that others may benefit. Originally developed by Jim Ramsay. Simplified by Mikulas Patocka.

2013-07-10dm: optimize reorder structureMikulas Patocka
This reorder actually improves performance by 20% (from 39.1s to 32.8s) on x86-64 quad core Opteron. I have no explanation for this, possibly it makes some other entries are better cache-aligned. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2013-07-10dm: optimize use SRCU and RCUMikulas Patocka
This patch removes "io_lock" and "map_lock" in struct mapped_device and "holders" in struct dm_table and replaces these mechanisms with sleepable-rcu. Previously, the code would call "dm_get_live_table" and "dm_table_put" to get and release table. Now, the code is changed to call "dm_get_live_table" and "dm_put_live_table". dm_get_live_table locks sleepable-rcu and dm_put_live_table unlocks it. dm_get_live_table_fast/dm_put_live_table_fast can be used instead of dm_get_live_table/dm_put_live_table. These *_fast functions use non-sleepable RCU, so the caller must not block between them. If the code changes active or inactive dm table, it must call dm_sync_table before destroying the old table.

2013-07-10dm bufio: submit writes outside lockMikulas Patocka
This patch changes dm-bufio so that it submits write I/Os outside of the lock. If the number of submitted buffers is greater than the number of requests on the target queue, submit_bio blocks. We want to block outside of the lock to improve latency of other threads that may need the lock. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2013-07-10dm cache: fix arm link errors with inlineMikulas Patocka
Use __always_inline to avoid a link failure with gcc 4.6 on ARM. gcc 4.7 is OK. It creates a function block_div.part.8, it references __udivdi3 and __umoddi3 and it is never called. The references to __udivdi3 and __umoddi3 cause a link failure.

2013-07-10dm: use __GFP_HIGHMEM in __vmallocMikulas Patocka
Use __GFP_HIGHMEM in __vmalloc. Pages allocated with __vmalloc can be allocated in high memory that is not directly mapped to kernel space, so use __GFP_HIGHMEM just like vmalloc does. This patch reduces memory pressure slightly because pages can be allocated in the high zone. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2013-07-10dm verity: fix inability to use a few specific devices sizesMikulas Patocka
Fix a boundary condition that caused failure for certain device sizes. The problem is reported at http://code.google.com/p/cryptsetup/issues/detail?id=160 For certain device sizes the number of hashes at a specific level was calculated incorrectly. It happens for example for a device with data and metadata block size 4096 that has 16385 blocks and algorithm sha256. The user can test if he is affected by this bug by running the "veritysetup verify" command and also by activating the dm-verity kernel driver and reading the whole block device. If it passes without an error, then the user is not affected. The condition for the bug is: Split the total number of data blocks (data_block_bits) into bit strings, each string has hash_per_block_bits bits. hash_per_block_bits is rounddown(log2(metadata_block_size/hash_digest_size)). Equivalently, you can say that you convert data_blocks_bits to 2^hash_per_block_bits base. If there some zero bit string below the most significant bit string and at least one bit below this zero bit string is set, then the bug happens. The same bug exists in the userspace veritysetup tool, so you must use fixed veritysetup too if you want to use devices that are affected by this boundary condition.

2013-07-10dm ioctl: set noio flag to avoid __vmalloc deadlockMikulas Patocka
Set noio flag while calling __vmalloc() because it doesn't fully respect gfp flags to avoid a possible deadlock (see commit 502624bdad3dba45dfaacaf36b7d83e39e74b2d2). This should be backported to stable kernels 3.8 and newer. The kernel 3.8 doesn't have memalloc_noio_save(), so we should set and restore process flag PF_MEMALLOC instead.

2013-07-10dm mpath: fix ioctl deadlock when no pathsHannes Reinecke
When multipath needs to retry an ioctl the reference to the current live table needs to be dropped. Otherwise a deadlock occurs when all paths are down: - dm_blk_ioctl takes a reference to the current table and spins in multipath_ioctl(). - A new table is being loaded, but upon resume the process hangs in dm_table_destroy() waiting for references to drop to zero. With this patch the reference to the old table is dropped prior to retry, thereby avoiding the deadlock.

2013-07-10arch: sparc: kernel: check the memory length before use strcpy().Chen Gang
For the related next strcpy(), the destination length is less than 512, but the source maximize length may be 'OPROMMAXPARAM' (4096) which is more than 512. One work flow may: openprom_sunos_ioctl() -> if (cmd == OPROMSETOPT) getstrings() -> will alloc buffer with size 'OPROMMAXPARAM'. opromsetopt() -> devide the buffer into 'var' and 'value' of_set_property() -> pass prom_setprop() -> pass ldom_set_var() And do not mind the additional 4 alignment buffer increasing, since 'sizeof(pkt) - sizeof(pkt.header)' is 4 alignment at least.

2013-07-10SUNRPC: Fix a deadlock in rpc_client_register()Trond Myklebust
Commit 384816051ca9125cd54750e59c780c2a2655fa4f (SUNRPC: fix races on PipeFS MOUNT notifications) introduces a regression when we call rpc_setup_pipedir() with RPCSEC_GSS as the auth flavour. By calling rpcauth_create() while holding the sn->pipefs_sb_lock, we end up deadlocking in gss_pipes_dentries_create_net(). Fix is to register the client and release the mutex before calling rpcauth_create().

2013-07-10Add trivial driver to disable Intel Smart ConnectMatthew Garrett
Intel Smart Connect is an Intel-specific ACPI interface for configuring devices to wake up at regular intervals so they can pull down mail or other internet updates, and then go to sleep again. If a user enables this in Windows and then reboots into Linux, the device may wake up if it's put to sleep. Since there's no Linux userland support for any of this, the machine will then remain awake until something else puts it back to sleep. I haven't figured out all that much about how this works (there's a bunch of different ACPI calls available on the device), but this seems to be enough to turn it off. We can add more features to this driver if anyone ever cares about figuring out what the rest of the calls do or writing some Linux userspace to implement the rest of it.

2013-07-10Add support driver for Intel Rapid Start TechnologyMatthew Garrett
Intel Rapid Start Technology is a firmware-based suspend-to-disk implementation. Once placed in S3, the device will wake once either a timeout elapses or the battery reaches a critical level. It will then resume to the firmware and copy the contents of RAM to a specialised partition, and then power off the machine. If the user turns the machine back on the firmware will copy the contents of the partition back to RAM and then resume from S3 as normal. This driver provides an interface for configuring the wakeup events and timeout. It still requires firmware support and an appropriate suspend partition.

2013-07-10CIFS: Reconnect durable handles for SMB2Pavel Shilovsky
On reconnects, we need to reopen file and then obtain all byte-range locks held by the client. SMB2 protocol provides feature to make this process atomic by reconnecting to the same file handle with all it's byte-range locks. This patch adds this capability for SMB2 shares.
