2021-03-02KVM: x86/xen: Fix return code when clearing vcpu_info and vcpu_time_infoDavid Woodhouse1-0/+4
When clearing the per-vCPU shared regions, set the return value to zero to indicate success. This was causing spurious errors to be returned to userspace on soft reset. Also add a paranoid BUILD_BUG_ON() for compat structure compatibility.

2021-03-02selftests: kvm: Mmap the entire vcpu mmap areaAaron Lewis1-2/+4
The vcpu mmap area may consist of more than just the kvm_run struct. Allocate enough space for the entire vcpu mmap area. Without this, on x86, the PIO page, for example, will be missing. This is problematic when dealing with an unhandled exception from the guest as the exception vector will be incorrectly reported as 0x0.

2021-03-02ALSA: hda/hdmi: let new platforms assign the pcm slot dynamicallyHui Wang1-1/+17
If the platform set the dyn_pcm_assign to true, it will call hdmi_find_pcm_slot() to find a pcm slot when hdmi/dp monitor is connected and need to create a pcm. So far only intel_hsw_common_init() and patch_nvhdmi() set the dyn_pcm_assign to true, here we let tgl platforms assign the pcm slot dynamically first, if the driver runs for a period of time and there is no regression reported, we could set no_fixed_assgin to true in the intel_hsw_common_init(), and then set it to true in the patch_nvhdmi(). This change comes from the discussion between Takashi and Kai Vehmanen.

ALSA/ASoC/SOF/SoundWire: fix Kconfig issues In January, Intel kbuild bot and Arnd Bergmann reported multiple issues with randconfig. This patchset builds on Arnd's suggestions to a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev and sof-pci-dev become helpers. This will result in minor changes required for developers/testers, i.e. modprobe snd-sof-pci will no longer result in a probe. The SOF CI was already updated to deal with this module dependency change and introduction of new modules. b) Fix SOF/SoundWire/DSP_config dependencies by moving the code required to detect SoundWire presence in ACPI tables to sound/hda.

2021-03-02btrfs: subpage: fix the false data csum mismatch errorQu Wenruo1-5/+16
[BUG] When running fstresss, we can hit strange data csum mismatch where the on-disk data is in fact correct (passes scrub). With some extra debug info added, we have the following traces: 0482us: btrfs_do_readpage: root=5 ino=284 offset=393216, submit force=0 pgoff=0 iosize=8192 0494us: btrfs_do_readpage: root=5 ino=284 offset=401408, submit force=0 pgoff=8192 iosize=4096 0498us: btrfs_submit_data_bio: root=5 ino=284 bio first bvec=393216 len=8192 0591us: btrfs_do_readpage: root=5 ino=284 offset=405504, submit force=0 pgoff=12288 iosize=36864 0594us: btrfs_submit_data_bio: root=5 ino=284 bio first bvec=401408 len=4096 0863us: btrfs_submit_data_bio: root=5 ino=284 bio first bvec=405504 len=36864 0933us: btrfs_verify_data_csum: root=5 ino=284 offset=393216 len=8192 0967us: btrfs_do_readpage: root=5 ino=284 offset=442368, skip beyond isize pgoff=49152 iosize=16384 1047us: btrfs_verify_data_csum: root=5 ino=284 offset=401408 len=4096 1163us: btrfs_verify_data_csum: root=5 ino=284 offset=405504 len=36864 1290us: check_data_csum: !!! root=5 ino=284 offset=438272 pg_off=45056 !!! 7387us: end_bio_extent_readpage: root=5 ino=284 before pending_read_bios=0 [CAUSE] Normally we expect all submitted bio reads to only touch the range we specified, and under subpage context, it means we should only touch the range specified in each bvec. But in data read path, inside end_bio_extent_readpage(), we have page zeroing which only takes regular page size into consideration. This means for subpage if we have an inode whose content looks like below: 0 16K 32K 48K 64K |///////| |///////| | |//| = data needs to be read from disk | | = hole And i_size is 64K initially. Then the following race can happen: T1 | T2 --------------------------------+-------------------------------- btrfs_do_readpage() | |- isize = 64K; | | At this time, the isize is | | 64K | | | |- submit_extent_page() | | submit previous assembled bio| | assemble bio for [0, 16K) | | | |- submit_extent_page() | submit read bio for [0, 16K) | assemble read bio for | [32K, 48K) | | | btrfs_setsize() | |- i_size_write(, 16K); | Now i_size is only 16K end_io() for [0K, 16K) | |- end_bio_extent_readpage() | |- btrfs_verify_data_csum() | | No csum error | |- i_size = 16K; | |- zero_user_segment(16K, | PAGE_SIZE); | !!! We zeroed range | !!! [32K, 48K) | | end_io for [32K, 48K) | |- end_bio_extent_readpage() | |- btrfs_verify_data_csum() | ! CSUM MISMATCH ! | ! As the range is zeroed now ! [FIX] To fix the problem, make end_bio_extent_readpage() to only zero the range of bvec. The bug only affects subpage read-write support, as for full read-only mount we can't change i_size thus won't hit the race condition.

So fix this by making btrfs_setxattr_trans() not start a transaction when we already have a handle on one, stored in current->journal_info, and use that handle. We are good to use the handle because at btrfs_mkdir() we did reserve space for the xattr and the inode item.

2021-03-02btrfs: don't flush from btrfs_delayed_inode_reserve_metadataNikolay Borisov2-2/+3
Calling btrfs_qgroup_reserve_meta_prealloc from btrfs_delayed_inode_reserve_metadata can result in flushing delalloc while holding a transaction and delayed node locks. This is deadlock prone. In the past multiple commits: * ae5e070eaca9 ("btrfs: qgroup: don't try to wait flushing if we're already holding a transaction") * 6f23277a49e6 ("btrfs: qgroup: don't commit transaction when we already hold the handle") Tried to solve various aspects of this but this was always a whack-a-mole game. Unfortunately those 2 fixes don't solve a deadlock scenario involving btrfs_delayed_node::mutex. Namely, one thread can call btrfs_dirty_inode as a result of reading a file and modifying its atime: PID: 6963 TASK: ffff8c7f3f94c000 CPU: 2 COMMAND: "test" #0 __schedule at ffffffffa529e07d #1 schedule at ffffffffa529e4ff #2 schedule_timeout at ffffffffa52a1bdd #3 wait_for_completion at ffffffffa529eeea <-- sleeps with delayed node mutex held #4 start_delalloc_inodes at ffffffffc0380db5 #5 btrfs_start_delalloc_snapshot at ffffffffc0393836 #6 try_flush_qgroup at ffffffffc03f04b2 #7 __btrfs_qgroup_reserve_meta at ffffffffc03f5bb6 <-- tries to reserve space and starts delalloc inodes. #8 btrfs_delayed_update_inode at ffffffffc03e31aa <-- acquires delayed node mutex #9 btrfs_update_inode at ffffffffc0385ba8 #10 btrfs_dirty_inode at ffffffffc038627b <-- TRANSACTIION OPENED #11 touch_atime at ffffffffa4cf0000 #12 generic_file_read_iter at ffffffffa4c1f123 #13 new_sync_read at ffffffffa4ccdc8a #14 vfs_read at ffffffffa4cd0849 #15 ksys_read at ffffffffa4cd0bd1 #16 do_syscall_64 at ffffffffa4a052eb #17 entry_SYSCALL_64_after_hwframe at ffffffffa540008c This will cause an asynchronous work to flush the delalloc inodes to happen which can try to acquire the same delayed_node mutex: PID: 455 TASK: ffff8c8085fa4000 CPU: 5 COMMAND: "kworker/u16:30" #0 __schedule at ffffffffa529e07d #1 schedule at ffffffffa529e4ff #2 schedule_preempt_disabled at ffffffffa529e80a #3 __mutex_lock at ffffffffa529fdcb <-- goes to sleep, never wakes up. #4 btrfs_delayed_update_inode at ffffffffc03e3143 <-- tries to acquire the mutex #5 btrfs_update_inode at ffffffffc0385ba8 <-- this is the same inode that pid 6963 is holding #6 cow_file_range_inline.constprop.78 at ffffffffc0386be7 #7 cow_file_range at ffffffffc03879c1 #8 btrfs_run_delalloc_range at ffffffffc038894c #9 writepage_delalloc at ffffffffc03a3c8f #10 __extent_writepage at ffffffffc03a4c01 #11 extent_write_cache_pages at ffffffffc03a500b #12 extent_writepages at ffffffffc03a6de2 #13 do_writepages at ffffffffa4c277eb #14 __filemap_fdatawrite_range at ffffffffa4c1e5bb #15 btrfs_run_delalloc_work at ffffffffc0380987 <-- starts running delayed nodes #16 normal_work_helper at ffffffffc03b706c #17 process_one_work at ffffffffa4aba4e4 #18 worker_thread at ffffffffa4aba6fd #19 kthread at ffffffffa4ac0a3d #20 ret_from_fork at ffffffffa54001ff To fully address those cases the complete fix is to never issue any flushing while holding the transaction or the delayed node lock. This patch achieves it by calling qgroup_reserve_meta directly which will either succeed without flushing or will fail and return -EDQUOT. In the latter case that return value is going to be propagated to btrfs_dirty_inode which will fallback to start a new transaction. That's fine as the majority of time we expect the inode will have BTRFS_DELAYED_NODE_INODE_DIRTY flag set which will result in directly copying the in-memory state.

2021-03-02btrfs: fix spurious free_space_tree remount warningBoris Burkov1-2/+2
The intended logic of the check is to catch cases where the desired free_space_tree setting doesn't match the mounted setting, and the remount is anything but ro->rw. However, it makes the mistake of checking equality on a masked integer (btrfs_test_opt) against a boolean (btrfs_fs_compat_ro). If you run the reproducer: $ mount -o space_cache=v2 dev mnt $ mount -o remount,ro mnt you would expect no warning, because the remount is not attempting to change the free space tree setting, but we do see the warning. To fix this, add explicit bool type casts to the condition. I tested a variety of transitions: sudo mount -o space_cache=v2 /dev/vg0/lv0 mnt/lol (fst enabled) mount -o remount,ro mnt/lol (no warning, no fst change) sudo mount -o remount,rw,space_cache=v1,clear_cache (no warning, ro->rw) sudo mount -o remount,rw,space_cache=v2 mnt (warning, rw->rw with change) sudo mount -o remount,ro mnt (no warning, no fst change) sudo mount -o remount,rw,space_cache=v2 mnt (no warning, no fst change) Reported-by: Chris Murphy <lists@colorremedies.com> CC: stable@vger.kernel.org # 5.11 Signed-off-by: Boris Burkov <boris@bur.io> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and intel-dspconfig, move the ACPI scan helpers to a dedicated module. This follows the same idea as NHLT helpers which are already handled as a dedicated module. The only functional change is that the kernel parameter to filter links is now handled by a different module, but that was only provided for developers needing work-arounds for early BIOS releases.

The Kconfig file is way too convoluted. Track platforms where SoundWire is supported, and add simpler conditions to make sure there is no module/built-in issue. The use of 'depends on' is less intuitive if a required 'depend' is missing, but that's a small price to pay for clarity and simplicity.

2021-03-02ASoC: SOF: ACPI: avoid reverse module dependencyArnd Bergmann9-176/+215
The SOF-ACPI driver is backwards from the normal Linux model, it has a generic driver that knows about all the specific drivers, as opposed to having hardware specific drivers that link against a common framework. This requires ugly Kconfig magic and leads to missed dependencies as seen in this link error: arm-linux-gnueabi-ld: sound/soc/sof/sof-pci-dev.o: in function `sof_acpi_probe': sof-pci-dev.c:(.text+0x1c): undefined reference to `snd_intel_dsp_driver_probe' Change it to use the normal probe order of starting with a specific device in a driver, turning the sof-acpi-dev.c driver into a library (exported symbols are name-spaced to avoid symbol pollution). For backwards-compatibility with previous Kconfigs, the default values for platform drivers uses the top-level ACPI configurations. The modules were also renamed to allow for gradual transitions in test scripts.

2021-03-02ALSA: hda: intel-nhlt: verify config typePierre-Louis Bossart2-9/+50
Multiple bug reports report issues with the SOF and SST drivers when dealing with single microphone cases. We currently read the DMIC array information unconditionally but we don't check that the configuration type is actually a mic array. When the DMIC link does not rely on a mic array configuration, the recommendation is to check the format information to infer the maximum number of channels, and map this to the number of microphones. This leaves a potential for a mismatch between actual microphones available in hardware and what the ACPI table contains, but we have no other source of information. Note that single microphone configurations can alternatively be handled with a 'mic array' configuration along with a 'vendor-defined' geometry.
