2023-10-28block: assert that we're not holding open_mutex over blk_report_disk_deadChristian Brauner1-0/+7
blk_report_disk_dead() has the following major callers: (1) del_gendisk() (2) blk_mark_disk_dead() Since del_gendisk() acquires disk->open_mutex it's clear that all callers are assumed to be called without disk->open_mutex held. In turn, blk_report_disk_dead() is called without disk->open_mutex held in del_gendisk(). All callers of blk_mark_disk_dead() call it without disk->open_mutex as well. Ensure that it is clear that blk_report_disk_dead() is called without disk->open_mutex on purpose by asserting it and a comment in the code.

2023-10-28block: move bdev_mark_dead out of disk_check_media_changeChristoph Hellwig4-18/+17
disk_check_media_change is mostly called from ->open where it makes little sense to mark the file system on the device as dead, as we are just opening it. So instead of calling bdev_mark_dead from disk_check_media_change move it into the few callers that are not in an open instance. This avoid calling into bdev_mark_dead and thus taking s_umount with open_mutex held.

2023-10-28block: WARN_ON_ONCE() when we remove active partitionsChristian Brauner1-13/+17
The logic for disk->open_partitions is: blkdev_get_by_*() -> bdev_is_partition() -> blkdev_get_part() -> blkdev_get_whole() // bdev_whole->bd_openers++ -> if (part->bd_openers == 0) disk->open_partitions++ part->bd_openers In other words, when we first claim/open a partition we increment disk->open_partitions and only when all part->bd_openers are closed will disk->open_partitions be zero. That should mean that disk->open_partitions is always > 0 as long as there's anyone that has an open partition. So the check for disk->open_partitions should mean that we can never remove an active partition that has a holder and holder ops set. Assert that in the code. The main disk isn't removed so that check doesn't work for disk->part0 which is what we want. After all we only care about partition not about the main disk.

2023-10-28block: simplify bdev_del_partition()Christian Brauner1-1/+12
BLKPG_DEL_PARTITION refuses to delete partitions that still have openers, i.e., that has an elevated @bdev->bd_openers count. If a device is claimed by setting @bdev->bd_holder and @bdev->bd_holder_ops @bdev->bd_openers and @bdev->bd_holders are incremented. @bdev->bd_openers is effectively guaranteed to be >= @bdev->bd_holders. So as long as @bdev->bd_openers isn't zero we know that this partition is still in active use and that there might still be @bdev->bd_holder and @bdev->bd_holder_ops set. The only current example is @fs_holder_ops for filesystems. But that means bdev_mark_dead() which calls into bdev->bd_holder_ops->mark_dead::fs_bdev_mark_dead() is a nop. As long as there's an elevated @bdev->bd_openers count we can't delete the partition and if there isn't an elevated @bdev->bd_openers count then there's no @bdev->bd_holder or @bdev->bd_holder_ops. So simply open-code what we need to do. This gets rid of one more instance where we acquire s_umount under @disk->open_mutex.

2023-10-28fs: Avoid grabbing sb->s_umount under bdev->bd_holder_lockJan Kara3-22/+38
The implementation of bdev holder operations such as fs_bdev_mark_dead() and fs_bdev_sync() grab sb->s_umount semaphore under bdev->bd_holder_lock. This is problematic because it leads to disk->open_mutex -> sb->s_umount lock ordering which is counterintuitive (usually we grab higher level (e.g. filesystem) locks first and lower level (e.g. block layer) locks later) and indeed makes lockdep complain about possible locking cycles whenever we open a block device while holding sb->s_umount semaphore. Implement a function bdev_super_lock_shared() which safely transitions from holding bdev->bd_holder_lock to holding sb->s_umount on alive superblock without introducing the problematic lock dependency. We use this function fs_bdev_sync() and fs_bdev_mark_dead().

2023-10-28bcache: Fixup error handling in register_cache()Jan Kara1-13/+10
Coverity has noticed that the printing of error message in register_cache() uses already freed bdev_handle to get to bdev. In fact the problem has been there even before commit "bcache: Convert to bdev_open_by_path()" just a bit more subtle one - cache object itself could have been freed by the time we looked at ca->bdev and we don't hold any reference to bdev either so even that could in principle go away (due to device unplug or similar). Fix all these problems by printing the error message before closing the bdev.

2023-10-28block: Provide bdev_open_* functionsJan Kara2-0/+58
Create struct bdev_handle that contains all parameters that need to be passed to blkdev_put() and provide bdev_open_* functions that return this structure instead of plain bdev pointer. This will eventually allow us to pass one more argument to blkdev_put() (renamed to bdev_release()) without too much hassle.
