| 75cb8e9 | Javier González | 28 July 2017, 13:13:16 UTC | lightnvm: pblk: advance bio according to lba index When a lba either hits the cache or corresponds to an empty entry in the L2P table, we need to advance the bio according to the position in which the lba is located. Otherwise, we will copy data in the wrong page, thus causing data corruption for the application. In case of a cache hit, we assumed that bio->bi_iter.bi_idx would contain the correct index, but this is no necessarily true. Instead, use the local bio advance counter and iterator. This guarantees that lbas hitting the cache are copied into the right bv_page. In case of an empty L2P entry, we omitted to advance the bio. In the cases when the same I/O also contains a cache hit, data corresponding to this lba will be copied to the wrong bv_page. Fix this by advancing the bio as we do in the case of a cache hit.

| 7b98da6 | Chris Wilson | 21 July 2017, 14:50:37 UTC | drm/i915: Force CPU synchronisation even if userspace requests ASYNC The goal here was to minimise doing any thing or any check inside the kernel that was not strictly required. For a userspace that assumes complete control over the cache domains, the kernel is usually using outdated information and may trigger clflushes where none were required. However, swapping is a situation where userspace has no knowledge of the domain transfer, and will leave the object in the CPU cache. The kernel must flush this out to the backing storage prior to use with the GPU. As we use an asynchronous task tracked by an implicit fence for this, we also need to cancel the ASYNC flag on the object so that the object will wait for the clflush to complete before being executed. This also absolves userspace of the responsibility imposed by commit 77ae9957897d ("drm/i915: Enable userspace to opt-out of implicit fencing") that its needed to ensure that the object was out of the CPU cache prior to use on the GPU.

| adf2783 | Chris Wilson | 21 July 2017, 14:50:36 UTC | drm/i915: Only skip updating execobject.offset after error I was being overly paranoid in not updating the execobject.offset after performing the fallback copy where we set reloc.presumed_offset to -1. The thinking was to ensure that a subsequent NORELOC execbuf would be forced to process the invalid relocations. However this is overkill so long as we *only* update the execobject.offset following a successful update of the relocation value witin the batch. If we have to repeat the execbuf due to a later interruption, then we may skip the relocations on the second pass (honouring NORELOC) since the execobject.offset match the actual offsets (even though reloc.presumed_offset is garbage). Subsequent calls to execbuf with NORELOC should themselves ensure that the reloc.presumed_offset have been corrected in case of future migration. Reporting back the actual execobject.offset, even when reloc.presumed_offset is garbage, ensures that reuse of those objects use the latest information to avoid relocations.

This fixes at least an initial YUV420 modeset (added in a follow-up patchset by Shashank) when booting with the screen off: after the initial HW readout and modeset which enables the scaler a subsequent modeset will disable the scaler which isn't properly allocated. This results in a funky HW state where the pipe scaler HW registers can't be modified and the normally black screen is grey and shifted to the right or jitters.

| 4706ca7 | Daniel Vetter | 19 July 2017, 12:54:55 UTC | drm/i915: Unbreak gpu reset vs. modeset locking Taking the modeset locks unconditionally isn't the greatest idea, because atm that part is still broken and times out (and then atomic keels over). And there's really no reason to do so, the old code didn't do that either. To make the patch a bit simpler let's also nuke 2 cases that are only around for the old mmioflip paths. Atomic nonblocking workers will not die (minus bugs) when a gpu reset happens. And of course this doesn't fix any of the gpu reset vs. modeset deadlock fun, but it at least stop modern CI machines from keeling over all over the place for no reason at all. And we still have the explicit testcases to run the fake gpu reset, so coverage isn't that much worse. v2: Split out additional changes on top, restrict this to purely reducing the critical section of modeset locks. v2: Review from Maarten - update comments - don't oops when state is NULL in intel_finish_reset, but try to at least still drop locks properly.

| d34cfeb | Ville Syrjälä | 14 July 2017, 15:52:27 UTC | drm/i915: Fix cursor updates on some platforms Turns out that just writing CURPOS isn't sufficient to move the cursor on some platforms. My 830 works just fine, but eg. 945 and PNV don't. On those platforms we need to arm even the CURPOS update with a CURBASE write. Even worse, a write to any of the cursor register apart from CURBASE will cancel an already pending cursor update. So if we have armed a CURCNTR/CURBASE update, a subsequent CURPOS write prior to vblank would cancel that armed update. Thus we're left with a cursor that doesn't appear to move, or even change shape. Fix the problem by always performing the CURBASE write after a CURPOS write. Bspec is somewhat unclear which platforms actually require this CURBASE write and which don't. So to keep it simple and to make sure we really fix the problem across all supported devices, let's just perform the CURBASE write unconditionally.

One place the code tested for failure was passing "0" as the GFP flags. This is most unusual and is probably meant to be GFP_NOIO, so that is changed. Also, allocation from ->extra_pool and ->prealloc_pool are repeated before releasing the previous allocation. This can deadlock if the code is servicing a write under high memory pressure. To avoid deadlocks, change these to use GFP_NOWAIT and leave the error handling in place.

| ae7a609 | John David Anglin | 25 July 2017, 21:11:26 UTC | parisc: Prevent TLB speculation on flushed pages on CPUs that only support equivalent aliases Helge noticed that we flush the TLB page in flush_cache_page but not in flush_cache_range or flush_cache_mm. For a long time, we have had random segmentation faults building packages on machines with PA8800/8900 processors. These machines only support equivalent aliases. We don't see these faults on machines that don't require strict coherency. So, it appears TLB speculation sometimes leads to cache corruption on machines that require coherency. This patch adds TLB flushes to flush_cache_range and flush_cache_mm when coherency is required. We only flush the TLB in flush_cache_page when coherency is required. The patch also optimizes flush_cache_range. It turns out we always have the right context to use flush_user_dcache_range_asm and flush_user_icache_range_asm. The patch has been tested for some time on rp3440, rp3410 and A500-44. It's been boot tested on c8000. No random segmentation faults were observed during testing.

LVM2 has to request multiple table reloads involving superblock updates in order to reflect proper size of SubLVs in the cluster. Before a stripe adding reshape starts, validate_raid_redundancy() fails as a result of that because it checks the total number of devices against the number of rebuild ones rather than the actual ones in the raid set (as retrieved from the superblock) thus resulting in failed raid4/5/6/10 redundancy checks. E.g. convert 3 stripes -> 7 stripes raid5 (which only allows for maximum 1 device to fail) requesting +4 delta disks causing 4 devices to rebuild during reshaping thus failing activation. To fix this, move validate_raid_redundancy() to get access to the current raid_set members.

Fix it by using the pdc_result struct instead when calling firmware and copy the return values back into the result struct when finished sucessfully.

| 9c5358e | James Smart | 17 July 2017, 20:59:39 UTC | nvme-fc: revise TRADDR parsing The FC-NVME spec hasn't locked down on the format string for TRADDR. Currently the spec is lobbying for "nn-<16hexdigits>:pn-<16hexdigits>" where the wwn's are hex values but not prefixed by 0x. Most implementations so far expect a string format of "nn-0x<16hexdigits>:pn-0x<16hexdigits>" to be used. The transport uses the match_u64 parser which requires a leading 0x prefix to set the base properly. If it's not there, a match will either fail or return a base 10 value. The resolution in T11 is pushing out. Therefore, to fix things now and to cover any eventuality and any implementations already in the field, this patch adds support for both formats. The change consists of replacing the token matching routine with a routine that validates the fixed string format, and then builds a local copy of the hex name with a 0x prefix before calling the system parser. Note: the same parser routine exists in both the initiator and target transports. Given this is about the only "shared" item, we chose to replicate rather than create an interdendency on some shared code.

To properly recovery/restart these i/o's we don't want to hard fail them, we want to treat them as temporary resource errors in which a delayed retry will work.

| 17024ad | Omar Sandoval | 20 July 2017, 22:10:35 UTC | Btrfs: fix early ENOSPC due to delalloc If a lot of metadata is reserved for outstanding delayed allocations, we rely on shrink_delalloc() to reclaim metadata space in order to fulfill reservation tickets. However, shrink_delalloc() has a shortcut where if it determines that space can be overcommitted, it will stop early. This made sense before the ticketed enospc system, but now it means that shrink_delalloc() will often not reclaim enough space to fulfill any tickets, leading to an early ENOSPC. (Reservation tickets don't care about being able to overcommit, they need every byte accounted for.) Fix it by getting rid of the shortcut so that shrink_delalloc() reclaims all of the metadata it is supposed to. This fixes early ENOSPCs we were seeing when doing a btrfs receive to populate a new filesystem, as well as early ENOSPCs Christoph saw when doing a big cp -r onto Btrfs.
