2020-03-27NFSv4/pnfs: Support a list of commit arrays in struct pnfs_ds_commit_infoTrond Myklebust
When we have multiple layout segments with different lists of mirrored data, we need to track the commits on a per layout segment basis. This patch adds a list to support this tracking in struct pnfs_ds_commit_info. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
2020-03-27ring-buffer: Make resize disable per cpu buffer instead of total bufferSteven Rostedt (VMware)
When the ring buffer becomes writable for even when the trace file is read, it must still not be resized. But since tracers can be activated while the trace file is being read, the irqsoff tracer can modify the per CPU buffers, and this can cause the reader of the trace file to update the wrong buffer's resize disable bit, as the irqsoff tracer swaps out cpu buffers. By making the resize disable per cpu_buffer, it makes the update follow the per cpu_buffer even if it's swapped out with the snapshot buffer and keeps the release of the trace file modifying the same data as the open did.

2020-03-27gfs2: change from write to read lock for sd_log_flush_lock in journal replayBob Peterson
Function gfs2_recover_func grabs the sd_log_flush_lock rw_semaphore in write mode. This is unnecessary because we only need to prevent log flush from using sd_log_bio bio while it does. Therefore, a read lock will be enough. This is a small step in cleaning up log flush. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
2020-03-27gfs2: instrumentation wrt ail1 stuckBob Peterson
Before this patch, if the ail1 flush got stuck for some reason, there were no clues as to why. This patch introduces a check for getting stuck for more than a minute, and if it happens, it dumps the items still remaining on the ail1 list. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
2020-03-27gfs2: don't lock sd_log_flush_lock in try_rgrp_unlinkBob Peterson
In function try_rgrp_unlink, we added a temporary lock of the sd_log_flush_lock while searching the bitmaps. This protected us from problems in which dinodes being freed were still in a state of flux because the rgrp was in an active transaction. It was a kludge. Now that we've straightened out the code for inode eviction, deletes, and all the recovery mess, we no longer need this kludge. This patch removes it, and should improve performance.

2020-03-27gfs2: Change inode qa_data to allow multiple usersBob Peterson
Before this patch, multiple users called gfs2_qa_alloc which allocated a qadata structure to the inode, if quotas are turned on. Later, in file close or evict, the structure was deleted with gfs2_qa_delete. But there can be several competing processes who need access to the structure. There were races between file close (release) and the others. Thus, a release could delete the structure out from under a process that relied upon its existence. For example, chown. This patch changes the management of the qadata structures to be a get/put scheme. Function gfs2_qa_alloc has been changed to gfs2_qa_get and if the structure is allocated, the count essentially starts out at 1. Function gfs2_qa_delete has been renamed to gfs2_qa_put, and the last guy to decrement the count to 0 frees the memory. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
2020-03-27gfs2: eliminate gfs2_rsqa_alloc in favor of gfs2_qa_allocBob Peterson
Before this patch, multiple callers called gfs2_rsqa_alloc to force the existence of a reservations structure and a quota data structure if needed. However, now the reservations are handled separately, so the quota data is only the quota data. So we eliminate the one in favor of just calling gfs2_qa_alloc directly.

2020-03-27dm clone metadata: Fix return type of dm_clone_nr_of_hydrated_regions()Nikos Tsironis
dm_clone_nr_of_hydrated_regions() returns the number of regions that have been hydrated so far. In order to do so it employs bitmap_weight(). Until now, the return type of dm_clone_nr_of_hydrated_regions() was unsigned long. Because bitmap_weight() returns an int, in case BITS_PER_LONG == 64 and the return value of bitmap_weight() is 2^31 (the maximum allowed number of regions for a device), the result is sign extended from 32 bits to 64 bits and an incorrect value is displayed, in the status output of dm-clone, as the number of hydrated regions. Fix this by having dm_clone_nr_of_hydrated_regions() return an unsigned int.

2020-03-27dm clone: Add missing casts to prevent overflows and data corruptionNikos Tsironis
Add missing casts when converting from regions to sectors. In case BITS_PER_LONG == 32, the lack of the appropriate casts can lead to overflows and miscalculation of the device sector. As a result, we could end up discarding and/or copying the wrong parts of the device, thus corrupting the device's data.

2020-03-27dm clone: Add overflow check for number of regionsNikos Tsironis
Add overflow check for clone->nr_regions variable, which holds the number of regions of the target. The overflow can occur with sufficiently large devices, if BITS_PER_LONG == 32. E.g., if the region size is 8 sectors (4K), the overflow would occur for device sizes > 34359738360 sectors (~16TB). This could result in multiple device sectors wrongly mapping to the same region number, due to the truncation from 64 bits to 32 bits, which would lead to data corruption.

2020-03-27dm clone: Fix handling of partial region discardsNikos Tsironis
There is a bug in the way dm-clone handles discards, which can lead to discarding the wrong blocks or trying to discard blocks beyond the end of the device. This could lead to data corruption, if the destination device indeed discards the underlying blocks, i.e., if the discard operation results in the original contents of a block to be lost. The root of the problem is the code that calculates the range of regions covered by a discard request and decides which regions to discard. Since dm-clone handles the device in units of regions, we don't discard parts of a region, only whole regions. The range is calculated as: rs = dm_sector_div_up(bio->bi_iter.bi_sector, clone->region_size); re = bio_end_sector(bio) >> clone->region_shift; , where 'rs' is the first region to discard and (re - rs) is the number of regions to discard. The bug manifests when we try to discard part of a single region, i.e., when we try to discard a block with size < region_size, and the discard request both starts at an offset with respect to the beginning of that region and ends before the end of the region. The root cause is the following comparison: if (rs == re) // skip discard and complete original bio immediately , which doesn't take into account that 'rs' might be greater than 're'. Thus, we then issue a discard request for the wrong blocks, instead of skipping the discard all together. Fix the check to also take into account the above case, so we don't end up discarding the wrong blocks. Also, add some range checks to dm_clone_set_region_hydrated() and dm_clone_cond_set_range(), which update dm-clone's region bitmap. Note that the aforementioned bug doesn't cause invalid memory accesses, because dm_clone_is_range_hydrated() returns True for this case, so the checks are just precautionary.

2020-03-27Merge series "ASoC: Intel: add SoundWire machine driver" from Pierre-Louis ↵Mark Brown
Bossart <pierre-louis.bossart@linux.intel.com>: To handle multiple hardware combinations, this patchset suggests a single machine driver which will create and initialize dailinks dynamically. This allows us to support new configurations easily, as shown with the TigerLake rt5682 example. Each configuration updates the card component string, and UCM can test for the presence of components to configure them as needed. Since we use a single the machine driver name, all previous ACPI tables need to be updated. That should have no impact since the machine drivers listed at the time were not upstreamed and are no longer maintained.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk fixes from Stephen Boyd: "A handful of clk driver fixes. Mostly they're around the i.MX drivers fixing the parents of a few clks and making KASAN happy with how the message passing code works. Besides that we have a TI driver fix for the RTC parent and a fix for the basic gate type registration functions introduced this release where they didn't actually pass the arguments in the right places to the multiplexer function down below" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: imx: Align imx sc clock parent msg structs to 4 clk: imx: Align imx sc clock msg structs to 4 clk: Pass correct arguments to __clk_hw_register_gate() clk: ti: am43xx: Fix clock parent for RTC clock clk: imx8mp: Correct the enet_qos parent clock clk: imx8mp: Correct IMX8MP_CLK_HDMI_AXI clock parent
