2022-05-26libperf evlist: Allow mixing per-thread and per-cpu mmapsAdrian Hunter1-29/+7
mmap_per_evsel() will skip events that do not match the CPU, so all CPUs can be iterated in any case.

2022-05-26perf tools: Allow all_cpus to be a superset of user_requested_cpusAdrian Hunter3-13/+19
To support collection of system-wide events with user requested CPUs, all_cpus must be a superset of user_requested_cpus. In order to support all_cpus to be a superset of user_requested_cpus, all_cpus must be used instead of user_requested_cpus when dealing with CPUs of all events instead of CPUs of requested events.

2022-05-26perf intel-pt: Track sideband system-wide when neededAdrian Hunter1-8/+10
User space tasks can migrate between CPUs, so when tracing selected CPUs, sideband for all CPUs is still needed. This is in preparation for allowing system-wide events on all CPUs while the user requested events are on only user requested CPUs.

2022-05-26perf auxtrace: Add mmap_needed to auxtrace_mmap_paramsAdrian Hunter4-6/+21
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. Prepare for that not being the case, which it won't be when sideband tracking events are allowed on all CPUs even when auxtrace is limited to selected CPUs.

2022-05-26NFSD: Fix possible sleep during nfsd4_release_lockowner()Chuck Lever1-8/+4
nfsd4_release_lockowner() holds clp->cl_lock when it calls check_for_locks(). However, check_for_locks() calls nfsd_file_get() / nfsd_file_put() to access the backing inode's flc_posix list, and nfsd_file_put() can sleep if the inode was recently removed. Let's instead rely on the stateowner's reference count to gate whether the release is permitted. This should be a reliable indication of locks-in-use since file lock operations and ->lm_get_owner take appropriate references, which are released appropriately when file locks are removed.

2022-05-26scsi: storvsc: Removing Pre Win8 related logicSaurabh Sengar1-116/+39
The latest storvsc code has already removed the support for windows 7 and earlier. There is still some code logic remaining which is there to support pre Windows 8 OS. This patch removes these stale logic. This patch majorly does three things : 1. Removes vmscsi_size_delta and its logic, as the vmscsi_request struct is same for all the OS post windows 8 there is no need of delta. 2. Simplify sense_buffer_size logic, as there is single buffer size for all the post windows 8 OS. 3. Embed the vmscsi_win8_extension structure inside the vmscsi_request, as there is no separate handling required for different OS.

2022-05-25Merge 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 ...

2022-05-25kcov: update pos before writing pc in trace functionCongyu Liu1-2/+12
In __sanitizer_cov_trace_pc(), previously we write pc before updating pos. However, some early interrupt code could bypass check_kcov_mode() check and invoke __sanitizer_cov_trace_pc(). If such interrupt is raised between writing pc and updating pos, the pc could be overitten by the recursive __sanitizer_cov_trace_pc(). As suggested by Dmitry, we cold update pos before writing pc to avoid such interleaving. Apply the same change to write_comp_data().

2022-05-25ocfs2: dlmfs: fix error handling of user_dlm_destroy_lockJunxiao Bi via Ocfs2-devel1-1/+15
When user_dlm_destroy_lock failed, it didn't clean up the flags it set before exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of lock is still in used, next time when unlink invokes this function, it will return succeed, and then unlink will remove inode and dentry if lock is not in used(file closed), but the dlm lock is still linked in dlm lock resource, then when bast come in, it will trigger a panic due to user-after-free. See the following panic call trace. To fix this, USER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink fail. For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN, USER_LOCK_BUSY is also required to be cleared. Even though spin lock is released in between, but USER_LOCK_IN_TEARDOWN is still set, for USER_LOCK_BUSY, if before every place that waits on this flag, USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow waits on the busy flag set by user_dlm_destroy_lock(), then we can simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails. Fix user_dlm_cluster_lock() which is the only function not following this.

2022-05-25ocfs2: dlmfs: don't clear USER_LOCK_ATTACHED when destroying lockJunxiao Bi1-1/+0
The following function is the only place that checks USER_LOCK_ATTACHED. This flag is set when lock request is granted through user_ast() and only the following function will clear it. Checking of this flag here is to make sure ocfs2_dlm_unlock is not issued if this lock is never granted. For example, lock file is created and then get removed, open file never happens. Clearing the flag here is not necessary because this is the only function that checks it, if another flow is executing user_dlm_destroy_lock(), it will bail out at the beginning because of USER_LOCK_IN_TEARDOWN and never check USER_LOCK_ATTACHED. Drop the clear, so we don't need take care of it for the following error handling patch. int user_dlm_destroy_lock(struct user_lock_res *lockres) { ... status = 0; if (!(lockres->l_flags & USER_LOCK_ATTACHED)) { spin_unlock(&lockres->l_lock); goto bail; } lockres->l_flags &= ~USER_LOCK_ATTACHED; lockres->l_flags |= USER_LOCK_BUSY; spin_unlock(&lockres->l_lock); status = ocfs2_dlm_unlock(conn, &lockres->l_lksb, DLM_LKF_VALBLK); if (status) { user_log_dlm_error("ocfs2_dlm_unlock", status, lockres); goto bail; } ... } V1 discussion with Joseph: https://lore.kernel.org/all/[email protected]/T/ Link: https://lkml.kernel.org/r/[email protected] Signed-off-by: Junxiao Bi <[email protected]> Reviewed-by: Joseph Qi <[email protected]> Cc: Mark Fasheh <[email protected]> Cc: Joel Becker <[email protected]> Cc: Junxiao Bi <[email protected]> Cc: Changwei Ge <[email protected]> Cc: Gang He <[email protected]> Cc: Jun Piao <[email protected]> Signed-off-by: Andrew Morton <[email protected]>

Pull documentation updates from Jonathan Corbet: "It was a moderately busy cycle for documentation; highlights include: - After a long period of inactivity, the Japanese translations are seeing some much-needed maintenance and updating. - Reworked IOMMU documentation - Some new documentation for static-analysis tools - A new overall structure for the memory-management documentation. This is an LSFMM outcome that, it is hoped, will help encourage developers to fill in the many gaps. Optimism is eternal...but hopefully it will work. - More Chinese translations. Plus the usual typo fixes, updates, etc" * tag 'docs-5.19' of git://git.lwn.net/linux: (70 commits) docs: pdfdocs: Add space for chapter counts >= 100 in TOC docs/zh_CN: Add dev-tools/gdb-kernel-debugging.rst Chinese translation input: Docs: correct ntrig.rst typo input: Docs: correct atarikbd.rst typos MAINTAINERS: Become the docs/zh_CN maintainer docs/zh_CN: fix devicetree usage-model translation mm,doc: Add new documentation structure Documentation: drop more IDE boot options and ide-cd.rst Documentation/process: use scripts/get_maintainer.pl on patches MAINTAINERS: Add entry for DOCUMENTATION/JAPANESE docs/trans/ja_JP/howto: Don't mention specific kernel versions docs/ja_JP/SubmittingPatches: Request summaries for commit references docs/ja_JP/SubmittingPatches: Add Suggested-by as a standard signature docs/ja_JP/SubmittingPatches: Randy has moved docs/ja_JP/SubmittingPatches: Suggest the use of scripts/get_maintainer.pl docs/ja_JP/SubmittingPatches: Update GregKH links Documentation/sysctl: document max_rcu_stall_to_panic Documentation: add missing angle bracket in cgroup-v2 doc Documentation: dev-tools: use literal block instead of code-block docs/zh_CN: add vm numa translation ...

2022-05-25selftests: vm: add the "settings" file with timeout variablePatrick Wang1-0/+1
The default "timeout" for one kselftest is 45 seconds, while some cases in run_vmtests.sh require more time. This will cause testing timeout like: not ok 4 selftests: vm: run_vmtests.sh # TIMEOUT 45 seconds Therefore, add the "settings" file with timeout variable so users can set the "timeout" value.

The "test_hmm.sh" file used by run_vmtests.sh dose not be installed into INSTALL_PATH. Thus run_vmtests.sh can not call it in INSTALL_PATH: --------------------------- running ./test_hmm.sh smoke --------------------------- ./run_vmtests.sh: line 74: ./test_hmm.sh: No such file or directory [FAIL] ----------------------- Add "test_hmm.sh" to TEST_FILES so that it will be installed.

2022-05-25selftests: vm: check numa_available() before operating "merge_across_nodes" ↵Patrick Wang1-3/+6
in ksm_tests Patch series "selftests: vm: a few fixup patches". This series contains three fixup patches for vm selftests. They are independent. Please see the patches. This patch (of 3): Currently, ksm_tests operates "merge_across_nodes" with NUMA either enabled or disabled. In a system with NUMA disabled, these operations will fail and output a misleading report given "merge_across_nodes" does not exist in sysfs: ---------------------------- running ./ksm_tests -M -p 10 ---------------------------- f /sys/kernel/mm/ksm/merge_across_nodes fopen: No such file or directory Cannot save default tunables [FAIL] ---------------------- So check numa_available() before those operations to skip them if NUMA is disabled.
