This flag is currently never cleared, which can in rare cases trigger a warn-on if it is still set but the block isn't InSync. So clear it when it isn't need, which includes if the replacement device has failed. Signed-off-by: NNeilBrown <neilb@suse.com>

During a node failure, We need to suspend read balancing so that the reads are directed to the first device and stale data is not read. Suspending writes is not required because these would be recorded and synced eventually. A new flag MD_CLUSTER_SUSPEND_READ_BALANCING is set in recover_prep(). area_resyncing() will respond true for the entire devices if this flag is set and the request type is READ. The flag is cleared in recover_done(). Signed-off-by: NGoldwyn Rodrigues <rgoldwyn@suse.com> Reported-By: NDavid Teigland <teigland@redhat.com> Signed-off-by: NNeilBrown <neilb@suse.com>

bitmap_read_sb is modifying mddev->bitmap_info.offset. This works for the first bitmap read. However, when multiple bitmaps need to be opened by the same node, it ends up corrupting the offset. Fix it by using a local variable. Also, bitmap_read_sb is not required in bitmap_copy_from_slot since it is called in bitmap_create. Remove bitmap_read_sb().

request_module() can return 256 (process exited) in some cases, which is not as specified in the documentation before the request_module() definition. Convert the error to -ENOENT. The positive error number results in bitmap_create() returning a value that is meant to be an error but doesn't look like one, so it is dereferenced as a point and causes a crash.

When we get a read error from the last working device, we don't try to repair it, and don't fail the device. We simple report a read error to the caller. However the current test for 'is this the last working device' is wrong. When there is only one fully working device, it assumes that a non-faulty device is that device. However a spare which is rebuilding would be non-faulty but so not the only working device. So change the test from "!Faulty" to "In_sync". If ->degraded says there is only one fully working device and this device is in_sync, this must be the one. This bug has existed since we allowed read_balance to read from a recovering spare in v3.0 Reported-and-tested-by: NAlexander Lyakas <alex.bolshoy@gmail.com> Fixes: 76073054 ("md/raid1: clean up read_balance.")

There is a bug that the bitmap superblock isn't initialised properly for dm-raid, so a new field can have garbage in new fields. (dm-raid does initialisation in the kernel - md initialised the superblock in mdadm). This means that for dm-raid we cannot currently trust the new ->nodes field. So: - use __GFP_ZERO to initialise the superblock properly for all new arrays - initialise all fields in bitmap_info in bitmap_new_disk_sb - ignore ->nodes for dm arrays (yes, this is a hack) This bug exposes dm-raid to bug in the (still experimental) md-cluster code, so it is suitable for -stable. It does cause crashes.

'reshape_position' tracks where in the reshape we have reached. 'reshape_safe' tracks where in the reshape we have safely recorded in the metadata. These are compared to determine when to update the metadata. So it is important that reshape_safe is initialised properly. Currently it isn't. When starting a reshape from the beginning it usually has the correct value by luck. But when reducing the number of devices in a RAID10, it has the wrong value and this leads to the metadata not being updated correctly. This can lead to corruption if the reshape is not allowed to complete. This patch is suitable for any -stable kernel which supports RAID10 reshape, which is 3.5 and later.

Cache size can grow or shrink due to various pressures at any time. So when we resize the cache as part of a 'grow' operation (i.e. change the size to allow more devices) we need to blocks that automatic growing/shrinking. So introduce a mutex. auto grow/shrink uses mutex_trylock() and just doesn't bother if there is a blockage. Resizing the whole cache holds the mutex to ensure that the correct number of new stripes is allocated. This bug can result in some stripes not being freed when an array is stopped. This leads to the kmem_cache not being freed and a subsequent array can try to use the same kmem_cache and get confused. Fixes: edbe83ab ("md/raid5: allow the stripe_cache to grow and shrink.")

This patch restores the slab creation sequence that was broken by commit 4066c33d and also reverts the portions that introduced the KMALLOC_LOOP_XXX macros.

Pull libnvdimm subsystem from Dan Williams: "The libnvdimm sub-system introduces, in addition to the libnvdimm-core, 4 drivers / enabling modules: NFIT: Instantiates an "nvdimm bus" with the core and registers memory devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface table). After registering NVDIMMs the NFIT driver then registers "region" devices. A libnvdimm-region defines an access mode and the boundaries of persistent memory media. A region may span multiple NVDIMMs that are interleaved by the hardware memory controller. In turn, a libnvdimm-region can be carved into a "namespace" device and bound to the PMEM or BLK driver which will attach a Linux block device (disk) interface to the memory. PMEM: Initially merged in v4.1 this driver for contiguous spans of persistent memory address ranges is re-worked to drive PMEM-namespaces emitted by the libnvdimm-core. In this update the PMEM driver, on x86, gains the ability to assert that writes to persistent memory have been flushed all the way through the caches and buffers in the platform to persistent media. See memcpy_to_pmem() and wmb_pmem(). BLK: This new driver enables access to persistent memory media through "Block Data Windows" as defined by the NFIT. The primary difference of this driver to PMEM is that only a small window of persistent memory is mapped into system address space at any given point in time. Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access different portions of the media. BLK-mode, by definition, does not support DAX. BTT: This is a library, optionally consumed by either PMEM or BLK, that converts a byte-accessible namespace into a disk with atomic sector update semantics (prevents sector tearing on crash or power loss). The sinister aspect of sector tearing is that most applications do not know they have a atomic sector dependency. At least today's disk's rarely ever tear sectors and if they do one almost certainly gets a CRC error on access. NVDIMMs will always tear and always silently. Until an application is audited to be robust in the presence of sector-tearing the usage of BTT is recommended.

Pull tracing updates from Steven Rostedt: "This patch series contains several clean ups and even a new trace clock "monitonic raw". Also some enhancements to make the ring buffer even faster. But the biggest and most noticeable change is the renaming of the ftrace* files, structures and variables that have to deal with trace events. Over the years I've had several developers tell me about their confusion with what ftrace is compared to events. Technically, "ftrace" is the infrastructure to do the function hooks, which include tracing and also helps with live kernel patching. But the trace events are a separate entity altogether, and the files that affect the trace events should not be named "ftrace". These include: include/trace/ftrace.h -> include/trace/trace_events.h include/linux/ftrace_event.h -> include/linux/trace_events.h Also, functions that are specific for trace events have also been renamed: ftrace_print_*() -> trace_print_*() (un)register_ftrace_event() -> (un)register_trace_event() ftrace_event_name() -> trace_event_name() ftrace_trigger_soft_disabled() -> trace_trigger_soft_disabled() ftrace_define_fields_##call() -> trace_define_fields_##call() ftrace_get_offsets_##call() -> trace_get_offsets_##call() Structures have been renamed: ftrace_event_file -> trace_event_file ftrace_event_{call,class} -> trace_event_{call,class} ftrace_event_buffer -> trace_event_buffer ftrace_subsystem_dir -> trace_subsystem_dir ftrace_event_raw_##call -> trace_event_raw_##call ftrace_event_data_offset_##call-> trace_event_data_offset_##call ftrace_event_type_funcs_##call -> trace_event_type_funcs_##call And a few various variables and flags have also been updated. This has been sitting in linux-next for some time, and I have not heard a single complaint about this rename breaking anything.

Pull tracing fixes from Steven Rostedt: "This isn't my 4.2 pull request (yet). I found a few more bugs that I would have sent to fix 4.1, but since 4.1 is already out, I'm sending this before sending my 4.2 request (which is ready to go). After fixing the previous filter issue reported by Vince Weaver, I could not come up with a situation where the operand counter (cnt) could go below zero, so I added a WARN_ON_ONCE(cnt < 0). Vince was able to trigger that warn on with his fuzzer test, but didn't have a filter input that caused it. Later, Sasha Levin was able to trigger that same warning, and was able to give me the filter string that triggered it. It was simply a single operation ">". I wrapped the filtering code in a userspace program such that I could single step through the logic. With a single operator the operand counter can legitimately go below zero, and should be reported to the user as an error, but should not produce a kernel warning. The WARN_ON_ONCE(cnt < 0) should be just a "if (cnt < 0) break;" and the code following it will produce the error message for the user. While debugging this, I found that there was another bug that let the pointer to the filter string go beyond the filter string. This too was fixed. Finally, there was a typo in a stub function that only gets compiled if trace events is disabled but tracing is enabled (I'm not even sure that's possible)" * tag 'trace-fixes-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix typo from "static inlin" to "static inline" tracing/filter: Do not allow infix to exceed end of string tracing/filter: Do not WARN on operand count going below zero

I've one other new driver from freescale on my radar, it's been posted and reviewed, I'd just like to get someone to give it a last look, so maybe I'll send it or maybe I'll leave it. There is no major nouveau changes in here, Ben was working on something big, and we agreed it was a bit late, there wasn't anything else he considered urgent to merge. There might be another msm pull for some bits that are waiting on arm-soc, I'll see how we time it.
