This reverts commit 2bb2b7b5. 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.

There are reports that the console kthreads block the global console lock when the system is going down, for example, reboot, panic. First part of the solution was to block kthreads in these problematic system states so they stopped handling newly added messages. Second part of the solution is to wait when for the kthreads when they are actively printing. It solves the problem when a message was printed before the system entered the problematic state and the kthreads managed to step in. A busy waiting has to be used because panic() can be called in any context and in an unknown state of the scheduler. There must be a timeout because the kthread might get stuck or sleeping and never release the lock. The timeout 10s is an arbitrary value inspired by the softlockup timeout.

There are known situations when the console kthreads are not reliable or does not work in principle, for example, early boot, panic, shutdown. For these situations there is the direct (legacy) mode when printk() tries to get console_lock() and flush the messages directly. It works very well during the early boot when the console kthreads are not available at all. It gets more complicated in the other situations when console kthreads might be actively printing and block console_trylock() in printk(). The same problem is in the legacy code as well. Any console_lock() owner could block console_trylock() in printk(). It is solved by a trick that the current console_lock() owner is responsible for printing all pending messages. It is actually the reason why there is the risk of softlockups and why the console kthreads were introduced. The console kthreads use the same approach. They are responsible for printing the messages by definition. So that they handle the messages anytime when they are awake and see new ones. The global console_lock is available when there is nothing to do. It should work well when the problematic context is correctly detected and printk() switches to the direct mode. But it seems that it is not enough in practice. There are reports that the messages are not printed during panic() or shutdown() even though printk() tries to use the direct mode here. The problem seems to be that console kthreads become active in these situation as well. They steel the job before other CPUs are stopped. Then they are stopped in the middle of the job and block the global console_lock. First part of the solution is to block console kthreads when the system is in a problematic state and requires the direct printk() mode.

This reverts commit 938ba408. The wait queue @log_wait never has exclusive waiters, so there is no need to use wake_up_interruptible_all(). Using wake_up_interruptible() was the correct function to wake all waiters. Since there are no exclusive waiters, erroneously changing wake_up_interruptible() to wake_up_interruptible_all() did not result in any behavior change. However, using wake_up_interruptible_all() on a wait queue without exclusive waiters is fundamentally wrong. Go back to using wake_up_interruptible() to wake all waiters.

Pull printk updates from Petr Mladek: - Offload writing printk() messages on consoles to per-console kthreads. It prevents soft-lockups when an extensive amount of messages is printed. It was observed, for example, during boot of large systems with a lot of peripherals like disks or network interfaces. It prevents live-lockups that were observed, for example, when messages about allocation failures were reported and a CPU handled consoles instead of reclaiming the memory. It was hard to solve even with rate limiting because it would need to take into account the amount of messages and the speed of all consoles. It is a must to have for real time. Otherwise, any printk() might break latency guarantees. The per-console kthreads allow to handle each console on its own speed. Slow consoles do not longer slow down faster ones. And printk() does not longer unpredictably slows down various code paths. There are situations when the kthreads are either not available or not reliable, for example, early boot, suspend, or panic. In these situations, printk() uses the legacy mode and tries to handle consoles immediately. - Add documentation for the printk index. * tag 'printk-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: printk, tracing: fix console tracepoint printk: remove @console_locked printk: extend console_lock for per-console locking printk: add kthread console printers printk: add functions to prefer direct printing printk: add pr_flush() printk: move buffer definitions into console_emit_next_record() caller printk: refactor and rework printing logic printk: add con_printk() macro for console details printk: call boot_delay_msec() in printk_delay() printk: get caller_id/timestamp after migration disable printk: wake waiters for safe and NMI contexts printk: wake up all waiters printk: add missing memory barrier to wake_up_klogd() printk: cpu sync always disable interrupts printk: rename cpulock functions printk/index: Printk index feature documentation MAINTAINERS: Add printk indexing maintainers on mention of printk_index

Pull slab updates from Vlastimil Babka: - Conversion of slub_debug stack traces to stackdepot, allowing more useful debugfs-based inspection for e.g. memory leak debugging. Allocation and free debugfs info now includes full traces and is sorted by the unique trace frequency. The stackdepot conversion was already attempted last year but reverted by ae14c63a. The memory overhead (while not actually enabled on boot) has been meanwhile solved by making the large stackdepot allocation dynamic. The xfstest issues haven't been reproduced on current kernel locally nor in -next, so the slab cache layout changes that originally made that bug manifest were probably not the root cause. - Refactoring of dma-kmalloc caches creation. - Trivial cleanups such as removal of unused parameters, fixes and clarifications of comments. - Hyeonggon Yoo joins as a reviewer. * tag 'slab-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: MAINTAINERS: add myself as reviewer for slab mm/slub: remove unused kmem_cache_order_objects max mm: slab: fix comment for __assume_kmalloc_alignment mm: slab: fix comment for ARCH_KMALLOC_MINALIGN mm/slub: remove unneeded return value of slab_pad_check mm/slab_common: move dma-kmalloc caches creation into new_kmalloc_cache() mm/slub: remove meaningless node check in ___slab_alloc() mm/slub: remove duplicate flag in allocate_slab() mm/slub: remove unused parameter in setup_object*() mm/slab.c: fix comments slab, documentation: add description of debugfs files for SLUB caches mm/slub: sort debugfs output by frequency of stack traces mm/slub: distinguish and print stack traces in debugfs files mm/slub: use stackdepot to save stack trace in objects mm/slub: move struct track init out of set_track() lib/stackdepot: allow requesting early initialization dynamically mm/slub, kunit: Make slub_kunit unaffected by user specified flags mm/slab: remove some unused functions

Commit c724c866 ("linux/types.h: remove unnecessary __bitwise__") was right that there are no users of __bitwise__ in the kernel, but it turns out there are user space users of it that do expect it. It is, after all, in the uapi directory, so user space usage is to be expected. Instead of reverting the commit completely, let's just clarify the situation so that it doesn't happen again, and have some in-code explanations for why that "__bitwise__" still exists.

Pull iomap updates from Darrick Wong: "There's a couple of corrections sent in by Andreas for some accounting errors. The biggest change this time around is that writeback errors longer clear pageuptodate nor does XFS invalidate the page cache anymore. This brings XFS (and gfs2/zonefs) behavior in line with every other Linux filesystem driver, and fixes some UAF bugs that only cropped up after willy turned on multipage folios for XFS in 5.18-rc1. Regrettably, it took all the way to the end of the 5.18 cycle to find the source of these bugs and reach a consensus that XFS' writeback failure behavior from 20 years ago is no longer necessary. Summary: - Fix a couple of accounting errors in the buffered io code. - Discontinue the practice of marking folios !uptodate and invalidating them when writeback fails. This fixes some UAF bugs when multipage folios are enabled, and brings the behavior of XFS/gfs/zonefs into alignment with the behavior of all the other Linux filesystems" * tag 'iomap-5.19-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: iomap: don't invalidate folios after writeback errors iomap: iomap_write_end cleanup iomap: iomap_write_failed fix

Pull erofs (and fscache) updates from Gao Xiang: "After working on it on the mailing list for more than half a year, we finally form 'erofs over fscache' feature into shape. Hopefully it could bring more possibility to the communities. The story mainly started from a new project what we called "RAFS v6" [1] for Nydus image service almost a year ago, which enhances EROFS to be a new form of one bootstrap (which includes metadata representing the whole fs tree) + several data-deduplicated content addressable blobs (actually treated as multiple devices). Each blob can represent one container image layer but not quite exactly since all new data can be fully existed in the previous blobs so no need to introduce another new blob. It is actually not a new idea (at least on my side it's much like a simpilied casync [2] for now) and has many benefits over per-file blobs or some other exist ways since typically each RAFS v6 image only has dozens of device blobs instead of thousands of per-file blobs. It's easy to be signed with user keys as a golden image, transfered untouchedly with minimal overhead over the network, kept in some type of storage conveniently, and run with (optional) runtime verification but without involving too many irrelevant features crossing the system beyond EROFS itself. At least it's our final goal and we're keeping working on it. There was also a good summary of this approach from the casync author [3]. Regardless further optimizations, this work is almost done in the previous Linux release cycles. In this round, we'd like to introduce on-demand load for EROFS with the fscache/cachefiles infrastructure, considering the following advantages: - Introduce new file-based backend to EROFS. Although each image only contains dozens of blobs but in densely-deployed runC host for example, there could still be massive blobs on a machine, which is messy if each blob is treated as a device. In contrast, fscache and cachefiles are really great interfaces for us to make them work. - Introduce on-demand load to fscache and EROFS. Previously, fscache is mainly used to caching network-likewise filesystems, now it can support on-demand downloading for local fses too with the exact localfs on-disk format. It has many advantages which we're been described in the latest patchset cover letter [4]. In addition to that, most importantly, the cached data is still stored in the original local fs on-disk format so that it's still the one signed with private keys but only could be partially available. Users can fully trust it during running. Later, users can also back up cachefiles easily to another machine. - More reliable on-demand approach in principle. After data is all available locally, user daemon can be no longer online in some use cases, which helps daemon crash recovery (filesystems can still in service) and hot-upgrade (user daemon can be upgraded more frequently due to new features or protocols introduced.) - Other format can also be converted to EROFS filesystem format over the internet on the fly with the new on-demand load feature and mounted. That is entirely possible with on-demand load feature as long as such archive format metadata can be fetched in advance like stargz. In addition, although currently our target user is Nydus image service [5], but laterly, it can be used for other use cases like on-demand system booting, etc. As for the fscache on-demand load feature itself, strictly it can be used for other local fses too. Laterly we could promote most code to the iomap infrastructure and also enhance it in the read-write way if other local fses are interested. Thanks David Howells for taking so much time and patience on this these months, many thanks with great respect here again! Thanks Jeffle for working on this feature and Xin Yin from Bytedance for asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and Yan Song for testing, much appeciated.

Pull fs idmapping updates from Christian Brauner: "This contains two minor updates: - An update to the idmapping documentation by Rodrigo making it easier to understand that we first introduce several use-cases that fail without idmapped mounts simply to explain how they can be handled with idmapped mounts. - When changing a mount's idmapping we now hold writers to make it more robust. This is similar to turning a mount ro with the difference that in contrast to turning a mount ro changing the idmapping can only ever be done once while a mount can transition between ro and rw as much as it wants. The vfs layer itself takes care to retrieve the idmapping of a mount once ensuring that the idmapping used for vfs permission checking is identical to the idmapping passed down to the filesystem. All filesystems with FS_ALLOW_IDMAP raised take the same precautions as the vfs in code-paths that are outside of direct control of the vfs such as ioctl()s. However, holding writers makes this more robust and predictable for both the kernel and userspace. This is a minor user-visible change. But it is extremely unlikely to matter. The caller must've created a detached mount via OPEN_TREE_CLONE and then handed that O_PATH fd to another process or thread which then must've gotten a writable fd for that mount and started creating files in there while the caller is still changing mount properties. While not impossible it will be an extremely rare corner-case and should in general be considered a bug in the application. Consider making a mount MOUNT_ATTR_NOEXEC or MOUNT_ATTR_NODEV while allowing someone else to perform lookups or exec'ing in parallel by handing them a copy of the OPEN_TREE_CLONE fd or another fd beneath that mount. I've pinged all major users of idmapped mounts pointing out this change and none of them have active writers on a mount while still changing mount properties. It would've been strange if they did. The rest and majority of the work will be coming through the overlayfs tree this cycle. In addition to overlayfs this cycle should also see support for idmapped mounts on erofs as I've acked a patch to this effect a little while ago" * tag 'fs.idmapped.v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fs: hold writers when changing mount's idmapping docs: Add small intro to idmap examples
