2022-07-17pagemap,pmem: introduce ->memory_failure()Shiyang Ruan1-0/+17
When memory-failure occurs, we call this function which is implemented by each kind of devices. For the fsdax case, pmem device driver implements it. Pmem device driver will find out the filesystem in which the corrupted page located in. With dax_holder notify support, we are able to notify the memory failure from pmem driver to upper layers. If there is something not support in the notify routine, memory_failure will fall back to the generic hanlder.

2022-07-17dax: introduce holder for dax_deviceShiyang Ruan2-2/+67
Patch series "v14 fsdax-rmap + v11 fsdax-reflink", v2. The patchset fsdax-rmap is aimed to support shared pages tracking for fsdax. It moves owner tracking from dax_assocaite_entry() to pmem device driver, by introducing an interface ->memory_failure() for struct pagemap. This interface is called by memory_failure() in mm, and implemented by pmem device. Then call holder operations to find the filesystem which the corrupted data located in, and call filesystem handler to track files or metadata associated with this page. Finally we are able to try to fix the corrupted data in filesystem and do other necessary processing, such as killing processes who are using the files affected. The call trace is like this: memory_failure() |* fsdax case |------------ |pgmap->ops->memory_failure() => pmem_pgmap_memory_failure() | dax_holder_notify_failure() => | dax_device->holder_ops->notify_failure() => | - xfs_dax_notify_failure() | |* xfs_dax_notify_failure() | |-------------------------- | | xfs_rmap_query_range() | | xfs_dax_failure_fn() | | * corrupted on metadata | | try to recover data, call xfs_force_shutdown() | | * corrupted on file data | | try to recover data, call mf_dax_kill_procs() |* normal case |------------- |mf_generic_kill_procs() The patchset fsdax-reflink attempts to add CoW support for fsdax, and takes XFS, which has both reflink and fsdax features, as an example. One of the key mechanisms needed to be implemented in fsdax is CoW. Copy the data from srcmap before we actually write data to the destination iomap. And we just copy range in which data won't be changed. Another mechanism is range comparison. In page cache case, readpage() is used to load data on disk to page cache in order to be able to compare data. In fsdax case, readpage() does not work. So, we need another compare data with direct access support. With the two mechanisms implemented in fsdax, we are able to make reflink and fsdax work together in XFS. This patch (of 14): To easily track filesystem from a pmem device, we introduce a holder for dax_device structure, and also its operation. This holder is used to remember who is using this dax_device: - When it is the backend of a filesystem, the holder will be the instance of this filesystem. - When this pmem device is one of the targets in a mapped device, the holder will be this mapped device. In this case, the mapped device has its own dax_device and it will follow the first rule. So that we can finally track to the filesystem we needed. The holder and holder_ops will be set when filesystem is being mounted, or an target device is being activated.

2022-07-17drm/amdkfd: add SPM support for SVMAlex Sierra1-13/+21
When CPU is connected throug XGMI, it has coherent access to VRAM resource. In this case that resource is taken from a table in the device gmc aperture base. This resource is used along with the device type, which could be DEVICE_PRIVATE or DEVICE_COHERENT to create the device page map region. Also, MIGRATE_VMA_SELECT_DEVICE_COHERENT flag is selected for coherent type case during migration to device.

2022-07-03zram: do not lookup algorithm in backends tableSergey Senozhatsky1-6/+5
Always use crypto_has_comp() so that crypto can lookup module, call usermodhelper to load the modules, wait for usermodhelper to finish and so on. Otherwise crypto will do all of these steps under CPU hot-plug lock and this looks like too much stuff to handle under the CPU hot-plug lock. Besides this can end up in a deadlock when usermodhelper triggers a code path that attempts to lock the CPU hot-plug lock, that zram already holds. An example of such deadlock: - path A. zram grabs CPU hot-plug lock, execs /sbin/modprobe from crypto and waits for modprobe to finish disksize_store zcomp_create __cpuhp_state_add_instance __cpuhp_state_add_instance_cpuslocked zcomp_cpu_up_prepare crypto_alloc_base crypto_alg_mod_lookup call_usermodehelper_exec wait_for_completion_killable do_wait_for_common schedule - path B. async work kthread that brings in scsi device. It wants to register CPUHP states at some point, and it needs the CPU hot-plug lock for that, which is owned by zram. async_run_entry_fn scsi_probe_and_add_lun scsi_mq_alloc_queue blk_mq_init_queue blk_mq_init_allocated_queue blk_mq_realloc_hw_ctxs __cpuhp_state_add_instance __cpuhp_state_add_instance_cpuslocked mutex_lock schedule - path C. modprobe sleeps, waiting for all aync works to finish. load_module do_init_module async_synchronize_full async_synchronize_cookie_domain schedule [senozhatsky@chromium.org: add comment] Link: https://lkml.kernel.org/r/20220624060606.1014474-1-senozhatsky@chromium.org Link: https://lkml.kernel.org/r/20220622023501.517125-1-senozhatsky@chromium.org Signed-off-by: Sergey Senozhatsky <senozhatsky@chromium.org> Cc: Minchan Kim <minchan@kernel.org> Cc: Nitin Gupta <ngupta@vflare.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2022-07-03mm: shrinkers: provide shrinkers with namesRoman Gushchin12-12/+16
Currently shrinkers are anonymous objects. For debugging purposes they can be identified by count/scan function names, but it's not always useful: e.g. for superblock's shrinkers it's nice to have at least an idea of to which superblock the shrinker belongs. This commit adds names to shrinkers. register_shrinker() and prealloc_shrinker() functions are extended to take a format and arguments to master a name. In some cases it's not possible to determine a good name at the time when a shrinker is allocated. For such cases shrinker_debugfs_rename() is provided. The expected format is: <subsystem>-<shrinker_type>[:<instance>]-<id> For some shrinkers an instance can be encoded as (MAJOR:MINOR) pair. After this change the shrinker debugfs directory looks like: $ cd /sys/kernel/debug/shrinker/ $ ls dquota-cache-16 sb-devpts-28 sb-proc-47 sb-tmpfs-42 mm-shadow-18 sb-devtmpfs-5 sb-proc-48 sb-tmpfs-43 mm-zspool:zram0-34 sb-hugetlbfs-17 sb-pstore-31 sb-tmpfs-44 rcu-kfree-0 sb-hugetlbfs-33 sb-rootfs-2 sb-tmpfs-49 sb-aio-20 sb-iomem-12 sb-securityfs-6 sb-tracefs-13 sb-anon_inodefs-15 sb-mqueue-21 sb-selinuxfs-22 sb-xfs:vda1-36 sb-bdev-3 sb-nsfs-4 sb-sockfs-8 sb-zsmalloc-19 sb-bpf-32 sb-pipefs-14 sb-sysfs-26 thp-deferred_split-10 sb-btrfs:vda2-24 sb-proc-25 sb-tmpfs-1 thp-zero-9 sb-cgroup2-30 sb-proc-39 sb-tmpfs-27 xfs-buf:vda1-37 sb-configfs-23 sb-proc-41 sb-tmpfs-29 xfs-inodegc:vda1-38 sb-dax-11 sb-proc-45 sb-tmpfs-35 sb-debugfs-7 sb-proc-46 sb-tmpfs-40 [roman.gushchin@linux.dev: fix build warnings] Link: https://lkml.kernel.org/r/Yr+ZTnLb9lJk6fJO@castle Reported-by: kernel test robot <lkp@intel.com> Link: https://lkml.kernel.org/r/20220601032227.4076670-4-roman.gushchin@linux.dev Signed-off-by: Roman Gushchin <roman.gushchin@linux.dev> Cc: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Cc: Dave Chinner <dchinner@redhat.com> Cc: Hillf Danton <hdanton@sina.com> Cc: Kent Overstreet <kent.overstreet@gmail.com> Cc: Muchun Song <songmuchun@bytedance.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

2022-06-24USB: gadget: Fix double-free bug in raw_gadget driverAlan Stern1-6/+7
Re-reading a recently merged fix to the raw_gadget driver showed that it inadvertently introduced a double-free bug in a failure pathway. If raw_ioctl_init() encounters an error after the driver ID number has been allocated, it deallocates the ID number before returning. But when dev_free() runs later on, it will then try to deallocate the ID number a second time. Closely related to this issue is another error in the recent fix: The ID number is stored in the raw_dev structure before the code checks to see whether the structure has already been initialized, in which case the new ID number would overwrite the earlier value. The solution to both bugs is to keep the new ID number in a local variable, and store it in the raw_dev structure only after the check for prior initialization. No errors can occur after that point, so the double-free will never happen.

2022-06-23dm mirror log: clear log bits up to BITS_PER_LONG boundaryMikulas Patocka1-1/+1
Commit 85e123c27d5c ("dm mirror log: round up region bitmap size to BITS_PER_LONG") introduced a regression on 64-bit architectures in the lvm testsuite tests: lvcreate-mirror, mirror-names and vgsplit-operation. If the device is shrunk, we need to clear log bits beyond the end of the device. The code clears bits up to a 32-bit boundary and then calculates lc->sync_count by summing set bits up to a 64-bit boundary (the commit changed that; previously, this boundary was 32-bit too). So, it was using some non-zeroed bits in the calculation and this caused misbehavior. Fix this regression by clearing bits up to BITS_PER_LONG boundary.

2022-06-23dm: fix BLK_STS_DM_REQUEUE handling when dm_io represents split bioMing Lei2-4/+8
Commit 7dd76d1feec7 ("dm: improve bio splitting and associated IO accounting") removed using cloned bio when dm io splitting is needed. Using bio_trim()+bio_inc_remaining() rather than bio_split()+bio_chain() causes multiple dm_io instances to share the same original bio, and it works fine if IOs are completed successfully. But a regression was caused for the case when BLK_STS_DM_REQUEUE is returned from any one of DM's cloned bios (whose dm_io share the same orig_bio). In this BLK_STS_DM_REQUEUE case only the mapped subset of the original bio for the current exact dm_io needs to be re-submitted. However, since the original bio is shared among all dm_io instances, the ->orig_bio actually only represents the last dm_io instance, so requeue can't work as expected. Also when more than one dm_io is requeued, the same original bio is requeued from all dm_io's completion handler, then race is caused. Fix this issue by still allocating one clone bio for completing io only, then io accounting can rely on ->orig_bio being unmodified. This is needed because the dm_io's sector_offset and sectors members are recorded relative to an unmodified ->orig_bio. In the future, we can go back to using bio_trim()+bio_inc_remaining() for dm's io splitting but then delay needing a bio clone only when handling BLK_STS_DM_REQUEUE, but that approach is a bit complicated (so it needs a development cycle): 1) bio clone needs to be done in task context 2) a block interface for unwinding bio is required Fixes: 7dd76d1feec7 ("dm: improve bio splitting and associated IO accounting") Reported-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Mike Snitzer <snitzer@kernel.org>

This reverts commit 2bb2b7b57f81255c13f4395ea911d6bdc70c9fe2. The testing of 5.19 release candidates revealed missing synchronization between early and regular console functionality. It would be possible to start the console kthreads later as a workaround. But it is clear that console lock serialized console drivers between each other. It opens a big area of possible problems that were not considered by people involved in the development and review. printk() is crucial for debugging kernel issues and console output is very important part of it. The number of consoles is huge and a proper review would take some time. As a result it need to be reverted for 5.19.

2022-06-23gpio: grgpio: Fix device removingUwe Kleine-König1-13/+1
If a platform device's remove callback returns non-zero, the device core emits a warning and still removes the device and calls the devm cleanup callbacks. So it's not save to not unregister the gpiochip because on the next request to a GPIO the driver accesses kfree()'d memory. Also if an IRQ triggers, the freed memory is accessed. Instead rely on the GPIO framework to ensure that after gpiochip_remove() all GPIOs are freed and so the corresponding IRQs are unmapped. This is a preparation for making platform remove callbacks return void.

2022-06-23xen/gntdev: Avoid blocking in unmap_grant_pages()Demi Marie Obenour2-51/+113
unmap_grant_pages() currently waits for the pages to no longer be used. In https://github.com/QubesOS/qubes-issues/issues/7481, this lead to a deadlock against i915: i915 was waiting for gntdev's MMU notifier to finish, while gntdev was waiting for i915 to free its pages. I also believe this is responsible for various deadlocks I have experienced in the past. Avoid these problems by making unmap_grant_pages async. This requires making it return void, as any errors will not be available when the function returns. Fortunately, the only use of the return value is a WARN_ON(), which can be replaced by a WARN_ON when the error is detected. Additionally, a failed call will not prevent further calls from being made, but this is harmless. Because unmap_grant_pages is now async, the grant handle will be sent to INVALID_GRANT_HANDLE too late to prevent multiple unmaps of the same handle. Instead, a separate bool array is allocated for this purpose. This wastes memory, but stuffing this information in padding bytes is too fragile. Furthermore, it is necessary to grab a reference to the map before making the asynchronous call, and release the reference when the call returns. It is also necessary to guard against reentrancy in gntdev_map_put(), and to handle the case where userspace tries to map a mapping whose contents have not all been freed yet.

Add usb product id of the Quectel RM500K module. RM500K provides 2 mandatory interfaces to Linux host after enumeration. - /dev/ttyUSB5: this is a serial interface for control path. User needs to write AT commands to this device node to query status, set APN, set PIN code, and enable/disable the data connection to 5G network. - ethX: this is the data path provided as a RNDIS devices. After the data connection has been established, Linux host can access 5G data network via this interface.
