2023-04-26blk-integrity: register sysfs attributes on struct deviceThomas Weißschuh
The "integrity" kobject only acted as a holder for static sysfs entries. It also was embedded into struct gendisk without managing it, violating assumptions of the driver core. Instead register the sysfs entries directly onto the struct device. Also drop the now unused member integrity_kobj from struct gendisk.

2023-04-27xfs: fix livelock in delayed allocation at ENOSPCDave Chinner
On a filesystem with a non-zero stripe unit and a large sequential write, delayed allocation will set a minimum allocation length of the stripe unit. If allocation fails because there are no extents long enough for an aligned minlen allocation, it is supposed to fall back to unaligned allocation which allows single block extents to be allocated. When the allocator code was rewritting in the 6.3 cycle, this fallback was broken - the old code used args->fsbno as the both the allocation target and the allocation result, the new code passes the target as a separate parameter. The conversion didn't handle the aligned->unaligned fallback path correctly - it reset args->fsbno to the target fsbno on failure which broke allocation failure detection in the high level code and so it never fell back to unaligned allocations. This resulted in a loop in writeback trying to allocate an aligned block, getting a false positive success, trying to insert the result in the BMBT. This did nothing because the extent already was in the BMBT (merge results in an unchanged extent) and so it returned the prior extent to the conversion code as the current iomap. Because the iomap returned didn't cover the offset we tried to map, xfs_convert_blocks() then retries the allocation, which fails in the same way and now we have a livelock.

2023-04-26KVM: x86: Preserve TDP MMU roots until they are explicitly invalidatedSean Christopherson
Preserve TDP MMU roots until they are explicitly invalidated by gifting the TDP MMU itself a reference to a root when it is allocated. Keeping a reference in the TDP MMU fixes a flaw where the TDP MMU exhibits terrible performance, and can potentially even soft-hang a vCPU, if a vCPU frequently unloads its roots, e.g. when KVM is emulating SMI+RSM. When KVM emulates something that invalidates _all_ TLB entries, e.g. SMI and RSM, KVM unloads all of the vCPUs roots (KVM keeps a small per-vCPU cache of previous roots). Unloading roots is a simple way to ensure KVM flushes and synchronizes all roots for the vCPU, as KVM flushes and syncs when allocating a "new" root (from the vCPU's perspective). In the shadow MMU, KVM keeps track of all shadow pages, roots included, in a per-VM hash table. Unloading a shadow MMU root just wipes it from the per-vCPU cache; the root is still tracked in the per-VM hash table. When KVM loads a "new" root for the vCPU, KVM will find the old, unloaded root in the per-VM hash table. Unlike the shadow MMU, the TDP MMU doesn't track "inactive" roots in a per-VM structure, where "active" in this case means a root is either in-use or cached as a previous root by at least one vCPU. When a TDP MMU root becomes inactive, i.e. the last vCPU reference to the root is put, KVM immediately frees the root (asterisk on "immediately" as the actual freeing may be done by a worker, but for all intents and purposes the root is gone). The TDP MMU behavior is especially problematic for 1-vCPU setups, as unloading all roots effectively frees all roots. The issue is mitigated to some degree in multi-vCPU setups as a different vCPU usually holds a reference to an unloaded root and thus keeps the root alive, allowing the vCPU to reuse its old root after unloading (with a flush+sync). The TDP MMU flaw has been known for some time, as until very recently, KVM's handling of CR0.WP also triggered unloading of all roots. The CR0.WP toggling scenario was eventually addressed by not unloading roots when _only_ CR0.WP is toggled, but such an approach doesn't Just Work for emulating SMM as KVM must emulate a full TLB flush on entry and exit to/from SMM. Given that the shadow MMU plays nice with unloading roots at will, teaching the TDP MMU to do the same is far less complex than modifying KVM to track which roots need to be flushed before reuse. Note, preserving all possible TDP MMU roots is not a concern with respect to memory consumption. Now that the role for direct MMUs doesn't include information about the guest, e.g. CR0.PG, CR0.WP, CR4.SMEP, etc., there are _at most_ six possible roots (where "guest_mode" here means L2): 1. 4-level !SMM !guest_mode 2. 4-level SMM !guest_mode 3. 5-level !SMM !guest_mode 4. 5-level SMM !guest_mode 5. 4-level !SMM guest_mode 6. 5-level !SMM guest_mode And because each vCPU can track 4 valid roots, a VM can already have all 6 root combinations live at any given time. Not to mention that, in practice, no sane VMM will advertise different guest.MAXPHYADDR values across vCPUs, i.e. KVM won't ever use both 4-level and 5-level roots for a single VM. Furthermore, the vast majority of modern hypervisors will utilize EPT/NPT when available, thus the guest_mode=%true cases are also unlikely to be utilized.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Split dm-bufio's rw_semaphore and rbtree. Offers improvements to dm-bufio's locking to allow increased concurrent IO -- particularly for read access for buffers already in dm-bufio's cache. - Also split dm-bio-prison-v1's spinlock and rbtree with comparable aim at improving concurrent IO (for the DM thinp target). - Both the dm-bufio and dm-bio-prison-v1 scaling of the number of locks and rbtrees used are managed by dm_num_hash_locks(). And the hash function used by both is dm_hash_locks_index(). - Allow DM targets to require DISCARD, WRITE_ZEROES and SECURE_ERASE to be split at the target specified boundary (in terms of max_discard_sectors, max_write_zeroes_sectors and max_secure_erase_sectors respectively). - DM verity error handling fix for check_at_most_once on FEC. - Update DM verity target to emit audit events on verification failure and more. - DM core ->io_hints improvements needed in support of new discard support that is added to the DM "zero" and "error" targets. - Fix missing kmem_cache_destroy() call in initialization error path of both the DM integrity and DM clone targets. - A couple fixes for DM flakey, also add "error_reads" feature. - Fix DM core's resume to not lock FS when the DM map is NULL; otherwise initial table load can race with FS mount that takes superblock's ->s_umount rw_semaphore. - Various small improvements to both DM core and DM targets. * tag 'for-6.4/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (40 commits) dm: don't lock fs when the map is NULL in process of resume dm flakey: add an "error_reads" option dm flakey: remove trailing space in the table line dm flakey: fix a crash with invalid table line dm ioctl: fix nested locking in table_clear() to remove deadlock concern dm: unexport dm_get_queue_limits() dm: allow targets to require splitting WRITE_ZEROES and SECURE_ERASE dm: add helper macro for simple DM target module init and exit dm raid: remove unused d variable dm: remove unnecessary (void*) conversions dm mirror: add DMERR message if alloc_workqueue fails dm: push error reporting down to dm_register_target() dm integrity: call kmem_cache_destroy() in dm_integrity_init() error path dm clone: call kmem_cache_destroy() in dm_clone_init() error path dm error: add discard support dm zero: add discard support dm table: allow targets without devices to set ->io_hints dm verity: emit audit events on verification failure and more dm verity: fix error handling for check_at_most_once on FEC dm: improve hash_locks sizing and hash function ...

KVM x86 MMU changes for 6.4: - Tweak FNAME(sync_spte) to avoid unnecessary writes+flushes when the guest is only adding new PTEs - Overhaul .sync_page() and .invlpg() to share the .sync_page() implementation, i.e. utilize .sync_page()'s optimizations when emulating invalidations - Clean up the range-based flushing APIs - Revamp the TDP MMU's reaping of Accessed/Dirty bits to clear a single A/D bit using a LOCK AND instead of XCHG, and skip all of the "handle changed SPTE" overhead associated with writing the entire entry - Track the number of "tail" entries in a pte_list_desc to avoid having to walk (potentially) all descriptors during insertion and deletion, which gets quite expensive if the guest is spamming fork() - Misc cleanups

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 updates for 6.4 - Numerous fixes for the pathological lock inversion issue that plagued KVM/arm64 since... forever. - New framework allowing SMCCC-compliant hypercalls to be forwarded to userspace, hopefully paving the way for some more features being moved to VMMs rather than be implemented in the kernel. - Large rework of the timer code to allow a VM-wide offset to be applied to both virtual and physical counters as well as a per-timer, per-vcpu offset that complements the global one. This last part allows the NV timer code to be implemented on top. - A small set of fixes to make sure that we don't change anything affecting the EL1&0 translation regime just after having having taken an exception to EL2 until we have executed a DSB. This ensures that speculative walks started in EL1&0 have completed. - The usual selftest fixes and improvements.

Pull io_uring updates from Jens Axboe: - Cleanup of the io-wq per-node mapping, notably getting rid of it so we just have a single io_wq entry per ring (Breno) - Followup to the above, move accounting to io_wq as well and completely drop struct io_wqe (Gabriel) - Enable KASAN for the internal io_uring caches (Breno) - Add support for multishot timeouts. Some applications use timeouts to wake someone waiting on completion entries, and this makes it a bit easier to just have a recurring timer rather than needing to rearm it every time (David) - Support archs that have shared cache coloring between userspace and the kernel, and hence have strict address requirements for mmap'ing the ring into userspace. This should only be parisc/hppa. (Helge, me) - XFS has supported O_DIRECT writes without needing to lock the inode exclusively for a long time, and ext4 now supports it as well. This is true for the common cases of not extending the file size. Flag the fs as having that feature, and utilize that to avoid serializing those writes in io_uring (me) - Enable completion batching for uring commands (me) - Revert patch adding io_uring restriction to what can be GUP mapped or not. This does not belong in io_uring, as io_uring isn't really special in this regard. Since this is also getting in the way of cleanups and improvements to the GUP code, get rid of if (me) - A few series greatly reducing the complexity of registered resources, like buffers or files. Not only does this clean up the code a lot, the simplified code is also a LOT more efficient (Pavel) - Series optimizing how we wait for events and run task_work related to it (Pavel) - Fixes for file/buffer unregistration with DEFER_TASKRUN (Pavel) - Misc cleanups and improvements (Pavel, me) * tag 'for-6.4/io_uring-2023-04-21' of git://git.kernel.dk/linux: (71 commits) Revert "io_uring/rsrc: disallow multi-source reg buffers" io_uring: add support for multishot timeouts io_uring/rsrc: disassociate nodes and rsrc_data io_uring/rsrc: devirtualise rsrc put callbacks io_uring/rsrc: pass node to io_rsrc_put_work() io_uring/rsrc: inline io_rsrc_put_work() io_uring/rsrc: add empty flag in rsrc_node io_uring/rsrc: merge nodes and io_rsrc_put io_uring/rsrc: infer node from ctx on io_queue_rsrc_removal io_uring/rsrc: remove unused io_rsrc_node::llist io_uring/rsrc: refactor io_queue_rsrc_removal io_uring/rsrc: simplify single file node switching io_uring/rsrc: clean up __io_sqe_buffers_update() io_uring/rsrc: inline switch_start fast path io_uring/rsrc: remove rsrc_data refs io_uring/rsrc: fix DEFER_TASKRUN rsrc quiesce io_uring/rsrc: use wq for quiescing io_uring/rsrc: refactor io_rsrc_ref_quiesce io_uring/rsrc: remove io_rsrc_node::done io_uring/rsrc: use nospec'ed indexes ...
