2022-05-26perf test: Add checking for perf stat CSV output.Claire Jensen2-0/+195
Counts expected fields for various commands. No testing added for summary mode since it is broken. An example of the summary output is: summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle ,,,,,1.37,stalled cycles per insn This should be: summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle summary,,,,,,1.37,stalled cycles per insn The output has 7 fields when it should have 8. Additionally, the newline spacing is wrong, so it was excluded from testing until a fix is made. Committer testing: $ perf test "perf stat CSV output" 88: perf stat CSV output linter : Ok $ $ perf test -v "perf stat CSV output" Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc 88: perf stat CSV output linter : --- start --- test child forked, pid 2622839 Checking CSV output: no args [Success] Checking CSV output: system wide [Skip] paranoid and not root Checking CSV output: system wide [Skip] paranoid and not root Checking CSV output: interval [Success] Checking CSV output: event [Success] Checking CSV output: per core [Skip] paranoid and not root Checking CSV output: per thread [Skip] paranoid and not root Checking CSV output: per die [Skip] paranoid and not root Checking CSV output: per node [Skip] paranoid and not root Checking CSV output: per socket [Skip] paranoid and not root test child finished with 0 ---- end ---- perf stat CSV output linter: Ok $ I did a s/parnoia/paranoid/g on the [Skip] lines.

Currently, user_requested_cpus supplants system-wide CPUs when the evlist has_user_cpus. Change that so that system-wide events retain their own CPUs and they are added to all_cpus.

2022-05-26perf stat: Add requires_cpu flag for uncoreAdrian Hunter5-6/+7
Uncore events require a CPU i.e. it cannot be -1. The evsel system_wide flag is intended for events that should be on every CPU, which does not make sense for uncore events because uncore events do not map one-to-one with CPUs. These 2 requirements are not exactly the same, so introduce a new flag 'requires_cpu' for the uncore case.

Add mmap_needed to auxtrace_mmap_params. Currently an auxtrace mmap is always attempted even if the event is not an auxtrace event. That works because, when AUX area tracing, there is always an auxtrace event first for every mmap.

The btf__load_from_kernel_by_id() only takes one arg, not two. Committer notes: I tested it just with an older libbpf, one where btf__load_from_kernel_by_id() wasn't introduced yet. A test with a newer dynamic libbpf would fail because the btf__load_from_kernel_by_id() is there, but takes just one arg.

2022-05-26Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linuxLinus Torvalds104-2675/+4689
Pull xfs updates from Dave Chinner: "This is a big update with lots of new code. The summary below them all, so I'll just touch on teh higlights. The two main new features are Large Extent Counts and Logged Attribute Replay - these are two new foundational features that we are building more complex future features on top of. For upcoming functionality, we need to be able to store hundreds of millions of xattrs per inode. The Large Extent Count feature removes the limits that prevent this scale of xattr storage, and while we were modifying the on disk extent count format we also increased the number of data extents we support per inode from 2^32 to 2^47. We also need to be able to modify xattrs as part of larger atomic transactions rather than as standalone transactions. The Logged Attribute Replay feature introduces the infrastructure that allows us to use intents to record the attribute modifications in the journal before we start them, hence allowing other atomic transactions to log attribute modification intents and then defer the actual modification to later. If we then crash, log recovery then guarantees that the attribute is replayed in the context of the atomic transaction that logged the intent. A significant chunk of the commits in this merge are for the base attribute replay functionality along with fixes, improvements and cleanups related to this new functioanlity. Allison deserves a big round of thanks for her ongoing work to get this functionality into XFS. There are also many other smaller changes and improvements, so overall this is one of the bigger XFS merge requests in some time. I will be following up next week with another smaller pull request - we already have another round of fixes and improvements to the logged attribute replay functionality just about ready to go. They'll soak and test over the next week, and I'll send a pull request for them near the end of the merge window. Summary: - support for printk message indexing. - large extent counts to provide support for up to 2^47 data extents and 2^32 attribute extents, allowing us to scale beyond 4 billion data extents to billions of xattrs per inode. - conversion of various flags fields to be consistently declared as unsigned bit fields. - improvements to realtime extent accounting and converts them to per-cpu counters to match all the other block and inode accounting. - reworks core log formatting code to reduce iterations, have a shorter, cleaner fast path and generally be easier to understand and maintain. - improvements to rmap btree searches that reduce overhead by up to 30% resulting in xfs_scrub runtime reductions of 15%. - improvements to reflink that remove the size limitations in remapping operations and greatly reduce the size of transaction reservations. - reworks the minimum log size calculations to allow us to change transaction reservations without changing the minimum supported log size. - removal of quota warning support as it has never been used on Linux. - intent whiteouts to allow us to cancel intents that are completed entirely in memory rather than having use CPU and disk bandwidth formatting and writing them into the journal when it is not necessary. This makes rmap, reflink and extent freeing slightly more efficient, but provides massive improvements for.... - Logged Attribute Replay feature support. This is a fundamental change to the way we modify attributes, laying the foundation for future integration of attribute modifications as part of other atomic transactional operations the filesystem performs. - Lots of cleanups and fixes for the logged attribute replay functionality" * tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (124 commits) xfs: can't use kmem_zalloc() for attribute buffers xfs: detect empty attr leaf blocks in xfs_attr3_leaf_verify xfs: ATTR_REPLACE algorithm with LARP enabled needs rework xfs: use XFS_DA_OP flags in deferred attr ops xfs: remove xfs_attri_remove_iter xfs: switch attr remove to xfs_attri_set_iter xfs: introduce attr remove initial states into xfs_attr_set_iter xfs: xfs_attr_set_iter() does not need to return EAGAIN xfs: clean up final attr removal in xfs_attr_set_iter xfs: remote xattr removal in xfs_attr_set_iter() is conditional xfs: XFS_DAS_LEAF_REPLACE state only needed if !LARP xfs: split remote attr setting out from replace path xfs: consolidate leaf/node states in xfs_attr_set_iter xfs: kill XFS_DAC_LEAF_ADDNAME_INIT xfs: separate out initial attr_set states xfs: don't set quota warning values xfs: remove warning counters from struct xfs_dquot_res xfs: remove quota warning limit from struct xfs_quota_limits xfs: rework deferred attribute operation setup xfs: make xattri_leaf_bp more useful ...

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux 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

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 ae14c63a9f20. 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
2022-05-25linux/types.h: reinstate "__bitwise__" macro for user space useLinus Torvalds1-0/+3
Commit c724c866bb70 ("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
