Pull remoteproc updates from Bjorn Andersson: "This adds support to the remoteproc core for detaching Linux from a running remoteproc, e.g. to reboot Linux while leaving the remoteproc running, and it enable this support in the stm32 remoteproc driver. It also introduces a property for memory carveouts to track if they are iomem or system ram, to enable proper handling of the differences. The imx_rproc received a number of fixes and improvements, in particular support for attaching to already running remote processors and i.MX8MQ and i.MX8MM support.

Pull tracing updates from Steven Rostedt: "New feature: - A new "func-no-repeats" option in tracefs/options directory. When set the function tracer will detect if the current function being traced is the same as the previous one, and instead of recording it, it will keep track of the number of times that the function is repeated in a row. And when another function is recorded, it will write a new event that shows the function that repeated, the number of times it repeated and the time stamp of when the last repeated function occurred. Enhancements: - In order to implement the above "func-no-repeats" option, the ring buffer timestamp can now give the accurate timestamp of the event as it is being recorded, instead of having to record an absolute timestamp for all events. This helps the histogram code which no longer needs to waste ring buffer space. - New validation logic to make sure all trace events that access dereferenced pointers do so in a safe way, and will warn otherwise. Fixes: - No longer limit the PIDs of tasks that are recorded for "saved_cmdlines" to PID_MAX_DEFAULT (32768), as systemd now allows for a much larger range. This caused the mapping of PIDs to the task names to be dropped for all tasks with a PID greater than 32768. - Change trace_clock_global() to never block. This caused a deadlock. Clean ups: - Typos, prototype fixes, and removing of duplicate or unused code. - Better management of ftrace_page allocations" * tag 'trace-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (32 commits) tracing: Restructure trace_clock_global() to never block tracing: Map all PIDs to command lines ftrace: Reuse the output of the function tracer for func_repeats tracing: Add "func_no_repeats" option for function tracing tracing: Unify the logic for function tracing options tracing: Add method for recording "func_repeats" events tracing: Add "last_func_repeats" to struct trace_array tracing: Define new ftrace event "func_repeats" tracing: Define static void trace_print_time() ftrace: Simplify the calculation of page number for ftrace_page->records some more ftrace: Store the order of pages allocated in ftrace_page tracing: Remove unused argument from "ring_buffer_time_stamp() tracing: Remove duplicate struct declaration in trace_events.h tracing: Update create_system_filter() kernel-doc comment tracing: A minor cleanup for create_system_filter() kernel: trace: Mundane typo fixes in the file trace_events_filter.c tracing: Fix various typos in comments scripts/recordmcount.pl: Make vim and emacs indent the same scripts/recordmcount.pl: Make indent spacing consistent tracing: Add a verifier to check string pointers for trace events ...

Pull orangefs updates from Mike Marshall: "orangefs: implement orangefs_readahead mm/readahead.c/read_pages was quite a bit different back when I put my open-coded readahead logic into orangefs_readpage. That logic seemed to work as designed back then, it is a trainwreck now. This implements orangefs_readahead using the new xarray and readahead_expand features and removes all my open-coded readahead logic. This results in an extreme read performance improvement, these sample numbers are from my test VM: Here's an example of what's upstream in 5.11.8-200.fc33.x86_64: 30+0 records in 30+0 records out 125829120 bytes (126 MB, 120 MiB) copied, 5.77943 s, 21.8 MB/s And here's this version of orangefs_readahead on top of 5.12.0-rc4: 30+0 records in 30+0 records out 125829120 bytes (126 MB, 120 MiB) copied, 0.325919 s, 386 MB/s There are four xfstest regressions with this patch.

Pull Landlock LSM from James Morris: "Add Landlock, a new LSM from Mickaël Salaün. Briefly, Landlock provides for unprivileged application sandboxing. From Mickaël's cover letter: "The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Because Landlock is a stackable LSM [1], it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Landlock empowers any process, including unprivileged ones, to securely restrict themselves. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil. In this current form, Landlock misses some access-control features. This enables to minimize this patch series and ease review. This series still addresses multiple use cases, especially with the combined use of seccomp-bpf: applications with built-in sandboxing, init systems, security sandbox tools and security-oriented APIs [2]" The cover letter and v34 posting is here: https://lore.kernel.org/linux-security-module/20210422154123.13086-1-mic@digikod.net/ See also: https://landlock.io/ This code has had extensive design discussion and review over several years" Link: https://lore.kernel.org/lkml/50db058a-7dde-441b-a7f9-f6837fe8b69f@schaufler-ca.com/ [1] Link: https://lore.kernel.org/lkml/f646e1c7-33cf-333f-070c-0a40ad0468cd@digikod.net/ [2] * tag 'landlock_v34' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: landlock: Enable user space to infer supported features landlock: Add user and kernel documentation samples/landlock: Add a sandbox manager example selftests/landlock: Add user space tests landlock: Add syscall implementations arch: Wire up Landlock syscalls fs,security: Add sb_delete hook landlock: Support filesystem access-control LSM: Infrastructure management of the superblock landlock: Add ptrace restrictions landlock: Set up the security framework and manage credentials landlock: Add ruleset and domain management landlock: Add object management

The generic/464 xfstest causes kAFS to emit occasional warnings of the form: kAFS: vnode modified {100055:8a} 30->31 YFS.StoreData64 (c=6015) This indicates that the data version received back from the server did not match the expected value (the DV should be incremented monotonically for each individual modification op committed to a vnode). What is happening is that a lookup call is doing a bulk status fetch speculatively on a bunch of vnodes in a directory besides getting the status of the vnode it's actually interested in. This is racing with a StoreData operation (though it could also occur with, say, a MakeDir op). On the client, a modification operation locks the vnode, but the bulk status fetch only locks the parent directory, so no ordering is imposed there (thereby avoiding an avenue to deadlock). On the server, the StoreData op handler doesn't lock the vnode until it's received all the request data, and downgrades the lock after committing the data until it has finished sending change notifications to other clients - which allows the status fetch to occur before it has finished. This means that: - a status fetch can access the target vnode either side of the exclusive section of the modification - the status fetch could start before the modification, yet finish after, and vice-versa. - the status fetch and the modification RPCs can complete in either order. - the status fetch can return either the before or the after DV from the modification. - the status fetch might regress the locally cached DV. Some of these are handled by the previous fix[1], but that's not sufficient because it checks the DV it received against the DV it cached at the start of the op, but the DV might've been updated in the meantime by a locally generated modification op. Fix this by the following means: (1) Keep track of when we're performing a modification operation on a vnode. This is done by marking vnode parameters with a 'modification' note that causes the AFS_VNODE_MODIFYING flag to be set on the vnode for the duration. (2) Alter the speculation race detection to ignore speculative status fetches if either the vnode is marked as being modified or the data version number is not what we expected. Note that whilst the "vnode modified" warning does get recovered from as it causes the client to refetch the status at the next opportunity, it will also invalidate the pagecache, so changes might get lost.

Merge tag 'for-5.13/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Improve scalability of DM's device hash by switching to rbtree - Extend DM ioctl's DM_LIST_DEVICES_CMD handling to include UUID and allow filtering based on name or UUID prefix. - Various small fixes for typos, warnings, unused function, or needlessly exported interfaces. - Remove needless request_queue NULL pointer checks in DM thin and cache targets. - Remove unnecessary loop in DM core's __split_and_process_bio(). - Remove DM core's dm_vcalloc() and just use kvcalloc or kvmalloc_array instead (depending whether zeroing is useful). - Fix request-based DM's double free of blk_mq_tag_set in device remove after table load fails. - Improve DM persistent data performance on non-x86 by fixing packed structs to have a stated alignment. Also remove needless extra work from redundant calls to sm_disk_get_nr_free() and a paranoid BUG_ON() that caused duplicate checksum calculation. - Fix missing goto in DM integrity's bitmap_flush_interval error handling. - Add "reset_recalculate" feature flag to DM integrity. - Improve DM integrity by leveraging discard support to avoid needless re-writing of metadata and also use discard support to improve hash recalculation. - Fix race with DM raid target's reshape and MD raid4/5/6 resync that resulted in inconsistant reshape state during table reloads. - Update DM raid target to temove unnecessary discard limits for raid0 and raid10 now that MD has optimized discard handling for both raid levels. * tag 'for-5.13/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (26 commits) dm raid: remove unnecessary discard limits for raid0 and raid10 dm rq: fix double free of blk_mq_tag_set in dev remove after table load fails dm integrity: use discard support when recalculating dm integrity: increase RECALC_SECTORS to improve recalculate speed dm integrity: don't re-write metadata if discarding same blocks dm raid: fix inconclusive reshape layout on fast raid4/5/6 table reload sequences dm raid: fix fall-through warning in rs_check_takeover() for Clang dm clone metadata: remove unused function dm integrity: fix missing goto in bitmap_flush_interval error handling dm: replace dm_vcalloc() dm space map common: fix division bug in sm_ll_find_free_block() dm persistent data: packed struct should have an aligned() attribute too dm btree spine: remove paranoid node_check call in node_prep_for_write() dm space map disk: remove redundant calls to sm_disk_get_nr_free() dm integrity: add the "reset_recalculate" feature flag dm persistent data: remove unused return from exit_shadow_spine() dm cache: remove needless request_queue NULL pointer checks dm thin: remove needless request_queue NULL pointer check dm: unexport dm_{get,put}_table_device dm ebs: fix a few typos ...

This mostly affects the Freescale PAMU driver. - New IOMMU driver for Unisoc SOCs - ARM SMMU Updates from Will: - Drop vestigial PREFETCH_ADDR support (SMMUv3) - Elide TLB sync logic for empty gather (SMMUv3) - Fix "Service Failure Mode" handling (SMMUv3) - New Qualcomm compatible string (SMMUv2) - Removal of the AMD IOMMU performance counter writeable check on AMD. It caused long boot delays on some machines and is only needed to work around an errata on some older (possibly pre-production) chips. If someone is still hit by this hardware issue anyway the performance counters will just return 0. - Support for targeted invalidations in the AMD IOMMU driver. Before that the driver only invalidated a single 4k page or the whole IO/TLB for an address space.

Core changes: - A semantic change to handle pinmux and pinconf in explicit order while up until now we depended on the semantic order in the device tree. The device tree is a functional programming language and does not imply any order, so the right thing is for the pin control core to provide these semantics. - Add a new pinmux-select debugfs file which makes it possible to go in and select functions for a pin manually (iteratively, at the prompt) for debugging purposes. - Fixes to gpio regmap handling for a new pin control driver making use of regmap-gpio. - Use octal permissions on debugfs files. New drivers: - A massive rewrite of the former custom pin control driver for MIPS Broadcom devices to instead use the pin control subsystem. New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368, BCM63268 and BCM6318 SoC variants are implemented. - Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B in the Qualcomm PMIC GPIO driver.
