syzbot is hitting "INFO: trying to register non-static key." message [1], for "struct l2cap_chan"->tx_q.lock spinlock is not yet initialized when l2cap_chan_del() is called due to e.g. timeout. Since "struct l2cap_chan"->lock mutex is initialized at l2cap_chan_create() immediately after "struct l2cap_chan" is allocated using kzalloc(), let's as well initialize "struct l2cap_chan"->{tx_q,srej_q}.lock spinlocks there.

hci_chan can be created in 2 places: hci_loglink_complete_evt() if it is an AMP hci_chan, or l2cap_conn_add() otherwise. In theory, Only AMP hci_chan should be removed by a call to hci_disconn_loglink_complete_evt(). However, the controller might mess up, call that function, and destroy an hci_chan which is not initiated by hci_loglink_complete_evt(). This patch adds a verification that the destroyed hci_chan must have been init'd by hci_loglink_complete_evt().

Currently l2cap_chan_set_defaults() reset chan->conf_state to zero. However, there is a flag CONF_NOT_COMPLETE which is set when creating the l2cap_chan. It is suggested that the flag should be cleared when l2cap_chan is ready, but when l2cap_chan_set_defaults() is called, l2cap_chan is not yet ready. Therefore, we must set this flag as the default.

Commit eab2404b ("Bluetooth: Add BT_PHY socket option") added a dependency between socket lock and hci_dev->lock that could lead to deadlock. It turns out that hci_conn_get_phy() is not in any way relying on hdev being immutable during the runtime of this function, neither does it even look at any of the members of hdev, and as such there is no need to hold that lock. This fixes the lockdep splat below: ====================================================== WARNING: possible circular locking dependency detected 5.12.0-rc1-00026-g73d464503354 #10 Not tainted ------------------------------------------------------ bluetoothd/1118 is trying to acquire lock: ffff8f078383c078 (&hdev->lock){+.+.}-{3:3}, at: hci_conn_get_phy+0x1c/0x150 [bluetooth] but task is already holding lock: ffff8f07e831d920 (sk_lock-AF_BLUETOOTH-BTPROTO_L2CAP){+.+.}-{0:0}, at: l2cap_sock_getsockopt+0x8b/0x610 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #3 (sk_lock-AF_BLUETOOTH-BTPROTO_L2CAP){+.+.}-{0:0}: lock_sock_nested+0x72/0xa0 l2cap_sock_ready_cb+0x18/0x70 [bluetooth] l2cap_config_rsp+0x27a/0x520 [bluetooth] l2cap_sig_channel+0x658/0x1330 [bluetooth] l2cap_recv_frame+0x1ba/0x310 [bluetooth] hci_rx_work+0x1cc/0x640 [bluetooth] process_one_work+0x244/0x5f0 worker_thread+0x3c/0x380 kthread+0x13e/0x160 ret_from_fork+0x22/0x30 -> #2 (&chan->lock#2/1){+.+.}-{3:3}: __mutex_lock+0xa3/0xa10 l2cap_chan_connect+0x33a/0x940 [bluetooth] l2cap_sock_connect+0x141/0x2a0 [bluetooth] __sys_connect+0x9b/0xc0 __x64_sys_connect+0x16/0x20 do_syscall_64+0x33/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae -> #1 (&conn->chan_lock){+.+.}-{3:3}: __mutex_lock+0xa3/0xa10 l2cap_chan_connect+0x322/0x940 [bluetooth] l2cap_sock_connect+0x141/0x2a0 [bluetooth] __sys_connect+0x9b/0xc0 __x64_sys_connect+0x16/0x20 do_syscall_64+0x33/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae -> #0 (&hdev->lock){+.+.}-{3:3}: __lock_acquire+0x147a/0x1a50 lock_acquire+0x277/0x3d0 __mutex_lock+0xa3/0xa10 hci_conn_get_phy+0x1c/0x150 [bluetooth] l2cap_sock_getsockopt+0x5a9/0x610 [bluetooth] __sys_getsockopt+0xcc/0x200 __x64_sys_getsockopt+0x20/0x30 do_syscall_64+0x33/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae other info that might help us debug this: Chain exists of: &hdev->lock --> &chan->lock#2/1 --> sk_lock-AF_BLUETOOTH-BTPROTO_L2CAP Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(sk_lock-AF_BLUETOOTH-BTPROTO_L2CAP); lock(&chan->lock#2/1); lock(sk_lock-AF_BLUETOOTH-BTPROTO_L2CAP); lock(&hdev->lock); *** DEADLOCK *** 1 lock held by bluetoothd/1118: #0: ffff8f07e831d920 (sk_lock-AF_BLUETOOTH-BTPROTO_L2CAP){+.+.}-{0:0}, at: l2cap_sock_getsockopt+0x8b/0x610 [bluetooth] stack backtrace: CPU: 3 PID: 1118 Comm: bluetoothd Not tainted 5.12.0-rc1-00026-g73d464503354 #10 Hardware name: LENOVO 20K5S22R00/20K5S22R00, BIOS R0IET38W (1.16 ) 05/31/2017 Call Trace: dump_stack+0x7f/0xa1 check_noncircular+0x105/0x120 ? __lock_acquire+0x147a/0x1a50 __lock_acquire+0x147a/0x1a50 lock_acquire+0x277/0x3d0 ? hci_conn_get_phy+0x1c/0x150 [bluetooth] ? __lock_acquire+0x2e1/0x1a50 ? lock_is_held_type+0xb4/0x120 ? hci_conn_get_phy+0x1c/0x150 [bluetooth] __mutex_lock+0xa3/0xa10 ? hci_conn_get_phy+0x1c/0x150 [bluetooth] ? lock_acquire+0x277/0x3d0 ? mark_held_locks+0x49/0x70 ? mark_held_locks+0x49/0x70 ? hci_conn_get_phy+0x1c/0x150 [bluetooth] hci_conn_get_phy+0x1c/0x150 [bluetooth] l2cap_sock_getsockopt+0x5a9/0x610 [bluetooth] __sys_getsockopt+0xcc/0x200 __x64_sys_getsockopt+0x20/0x30 do_syscall_64+0x33/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae RIP: 0033:0x7fb73df33eee Code: 48 8b 0d 85 0f 0c 00 f7 d8 64 89 01 48 83 c8 ff c3 66 2e 0f 1f 84 00 00 00 00 00 90 f3 0f 1e fa 49 89 ca b8 37 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 52 0f 0c 00 f7 d8 64 89 01 48 RSP: 002b:00007fffcfbbbf08 EFLAGS: 00000203 ORIG_RAX: 0000000000000037 RAX: ffffffffffffffda RBX: 0000000000000019 RCX: 00007fb73df33eee RDX: 000000000000000e RSI: 0000000000000112 RDI: 0000000000000018 RBP: 0000000000000000 R08: 00007fffcfbbbf44 R09: 0000000000000000 R10: 00007fffcfbbbf3c R11: 0000000000000203 R12: 0000000000000000 R13: 0000000000000018 R14: 0000000000000000 R15: 0000556fcefc70d0 Fixes: eab2404b ("Bluetooth: Add BT_PHY socket option") Signed-off-by:

Not cancelling it has caused a bug where passive background scanning is disabled out of the blue, preventing BLE keyboards/mice to reconnect. Here is how it happens: After hci_req_stop_discovery, there is still le_scan_restart_work scheduled. Invocation of le_scan_restart_work causes a harmful le_scan_disable_work to be scheduled. This le_scan_disable_work will eventually disable passive scanning when the timer fires.

This rewrites the Broadcom bluetooth bindings in YAML and adds a GPIO handle for the BT_RST_N line as used on some platforms. The Ingenic UART binding was using this binding in its example DTS fragment, however mistakenly using "vcc-supply" for what is called "vbat-supply". The proper DTS files and the code in the kernel all use "vbat-supply" so fix up the example in this patch so we ge a clean check. Cc: devicetree@vger.kernel.org Signed-off-by:

An issue was found, where if a bluetooth client requests a broadcast advertisement with scan response data, it will not be properly registered with the controller. This is because at the time that the hci_cp_le_set_scan_param structure is created, the scan response will not yet have been received since it comes in a second MGMT call. With empty scan response, the request defaults to a non-scannable PDU type. On some controllers, the subsequent scan response request will fail due to incorrect PDU type, and others will succeed and not use the scan response. This fix allows the advertising parameters MGMT call to include a flag to let the kernel know whether a scan response will be coming, so that the correct PDU type is used in the first place. A bluetoothd change is also incoming to take advantage of it. To test this, I created a broadcast advertisement with scan response data and registered it on the hatch chromebook. Without this change, the request fails, and with it will succeed. Reviewed-by:

During suspend, there are a few scan enable and set event filter commands that don't need to be sent unless there are actual BR/EDR devices capable of waking the system. Check the HCI_PSCAN bit before writing scan enable and use a new dev flag, HCI_EVENT_FILTER_CONFIGURED to control whether to clear the event filter. Signed-off-by:

When suspending, Bluetooth disconnects all connected peers devices. If an LE connection is started but isn't completed, we will see an LE Create Connection Cancel instead of an HCI disconnect. This just adds a check to see if an LE cancel was the last disconnected device and wake the suspend thread when that is the case. Signed-off-by:

Pull performance event updates from Ingo Molnar: - Add CPU-PMU support for Intel Sapphire Rapids CPUs - Extend the perf ABI with PERF_SAMPLE_WEIGHT_STRUCT, to offer two-parameter sampling event feedback. Not used yet, but is intended for Golden Cove CPU-PMU, which can provide both the instruction latency and the cache latency information for memory profiling events. - Remove experimental, default-disabled perfmon-v4 counter_freezing support that could only be enabled via a boot option. The hardware is hopelessly broken, we'd like to make sure nobody starts relying on this, as it would only end in tears. - Fix energy/power events on Intel SPR platforms - Simplify the uprobes resume_execution() logic - Misc smaller fixes. * tag 'perf-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/rapl: Fix psys-energy event on Intel SPR platform perf/x86/rapl: Only check lower 32bits for RAPL energy counters perf/x86/rapl: Add msr mask support perf/x86/kvm: Add Cascade Lake Xeon steppings to isolation_ucodes[] perf/x86/intel: Support CPUID 10.ECX to disable fixed counters perf/x86/intel: Add perf core PMU support for Sapphire Rapids perf/x86/intel: Filter unsupported Topdown metrics event perf/x86/intel: Factor out intel_update_topdown_event() perf/core: Add PERF_SAMPLE_WEIGHT_STRUCT perf/intel: Remove Perfmon-v4 counter_freezing support x86/perf: Use static_call for x86_pmu.guest_get_msrs perf/x86/intel/uncore: With > 8 nodes, get pci bus die id from NUMA info perf/x86/intel/uncore: Store the logical die id instead of the physical die id. x86/kprobes: Do not decode opcode in resume_execution()

Pull scheduler updates from Ingo Molnar: "Core scheduler updates: - Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the preempt=none/voluntary/full boot options (default: full), to allow distros to build a PREEMPT kernel but fall back to close to PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via a boot time selection. There's also the /debug/sched_debug switch to do this runtime. This feature is implemented via runtime patching (a new variant of static calls). The scope of the runtime patching can be best reviewed by looking at the sched_dynamic_update() function in kernel/sched/core.c. ( Note that the dynamic none/voluntary mode isn't 100% identical, for example preempt-RCU is available in all cases, plus the preempt count is maintained in all models, which has runtime overhead even with the code patching. ) The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast majority of distributions, are supposed to be unaffected. - Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that was found via rcutorture triggering a hang. The bug is that rcu_idle_enter() may wake up a NOCB kthread, but this happens after the last generic need_resched() check. Some cpuidle drivers fix it by chance but many others don't. In true 2020 fashion the original bug fix has grown into a 5-patch scheduler/RCU fix series plus another 16 RCU patches to address the underlying issue of missed preemption events. These are the initial fixes that should fix current incarnations of the bug. - Clean up rbtree usage in the scheduler, by providing & using the following consistent set of rbtree APIs: partial-order; less() based: - rb_add(): add a new entry to the rbtree - rb_add_cached(): like rb_add(), but for a rb_root_cached total-order; cmp() based: - rb_find(): find an entry in an rbtree - rb_find_add(): find an entry, and add if not found - rb_find_first(): find the first (leftmost) matching entry - rb_next_match(): continue from rb_find_first() - rb_for_each(): iterate a sub-tree using the previous two - Improve the SMP/NUMA load-balancer: scan for an idle sibling in a single pass. This is a 4-commit series where each commit improves one aspect of the idle sibling scan logic. - Improve the cpufreq cooling driver by getting the effective CPU utilization metrics from the scheduler - Improve the fair scheduler's active load-balancing logic by reducing the number of active LB attempts & lengthen the load-balancing interval. This improves stress-ng mmapfork performance. - Fix CFS's estimated utilization (util_est) calculation bug that can result in too high utilization values Misc updates & fixes: - Fix the HRTICK reprogramming & optimization feature - Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code - Reduce dl_add_task_root_domain() overhead - Fix uprobes refcount bug - Process pending softirqs in flush_smp_call_function_from_idle() - Clean up task priority related defines, remove *USER_*PRIO and USER_PRIO() - Simplify the sched_init_numa() deduplication sort - Documentation updates - Fix EAS bug in update_misfit_status(), which degraded the quality of energy-balancing - Smaller cleanups" * tag 'sched-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (51 commits) sched,x86: Allow !PREEMPT_DYNAMIC entry/kvm: Explicitly flush pending rcuog wakeup before last rescheduling point entry: Explicitly flush pending rcuog wakeup before last rescheduling point rcu/nocb: Trigger self-IPI on late deferred wake up before user resume rcu/nocb: Perform deferred wake up before last idle's need_resched() check rcu: Pull deferred rcuog wake up to rcu_eqs_enter() callers sched/features: Distinguish between NORMAL and DEADLINE hrtick sched/features: Fix hrtick reprogramming sched/deadline: Reduce rq lock contention in dl_add_task_root_domain() uprobes: (Re)add missing get_uprobe() in __find_uprobe() smp: Process pending softirqs in flush_smp_call_function_from_idle() sched: Harden PREEMPT_DYNAMIC static_call: Allow module use without exposing static_call_key sched: Add /debug/sched_preempt preempt/dynamic: Support dynamic preempt with preempt= boot option preempt/dynamic: Provide irqentry_exit_cond_resched() static call preempt/dynamic: Provide preempt_schedule[_notrace]() static calls preempt/dynamic: Provide cond_resched() and might_resched() static calls preempt: Introduce CONFIG_PREEMPT_DYNAMIC static_call: Provide DEFINE_STATIC_CALL_RET0() ... -

Pull io_uring updates from Jens Axboe: "Highlights from this cycles are things like request recycling and task_work optimizations, which net us anywhere from 10-20% of speedups on workloads that mostly are inline. This work was originally done to put io_uring under memcg, which adds considerable overhead. But it's a really nice win as well. Also worth highlighting is the LOOKUP_CACHED work in the VFS, and using it in io_uring. Greatly speeds up the fast path for file opens. Summary: - Put io_uring under memcg protection. We accounted just the rings themselves under rlimit memlock before, now we account everything. - Request cache recycling, persistent across invocations (Pavel, me) - First part of a cleanup/improvement to buffer registration (Bijan) - SQPOLL fixes (Hao) - File registration NULL pointer fixup (Dan) - LOOKUP_CACHED support for io_uring - Disable /proc/thread-self/ for io_uring, like we do for /proc/self - Add Pavel to the io_uring MAINTAINERS entry - Tons of code cleanups and optimizations (Pavel) - Support for skip entries in file registration (Noah)" * tag 'for-5.12/io_uring-2021-02-17' of git://git.kernel.dk/linux-block: (103 commits) io_uring: tctx->task_lock should be IRQ safe proc: don't allow async path resolution of /proc/thread-self components io_uring: kill cached requests from exiting task closing the ring io_uring: add helper to free all request caches io_uring: allow task match to be passed to io_req_cache_free() io-wq: clear out worker ->fs and ->files io_uring: optimise io_init_req() flags setting io_uring: clean io_req_find_next() fast check io_uring: don't check PF_EXITING from syscall io_uring: don't split out consume out of SQE get io_uring: save ctx put/get for task_work submit io_uring: don't duplicate io_req_task_queue() io_uring: optimise SQPOLL mm/files grabbing io_uring: optimise out unlikely link queue io_uring: take compl state from submit state io_uring: inline io_complete_rw_common() io_uring: move res check out of io_rw_reissue() io_uring: simplify iopoll reissuing io_uring: clean up io_req_free_batch_finish() io_uring: move submit side state closer in the ring ... -

Pull xfs updates from Darrick Wong: "There's a lot going on this time, which seems about right for this drama-filled year. Community developers added some code to speed up freezing when read-only workloads are still running, refactored the logging code, added checks to prevent file extent counter overflow, reduced iolock cycling to speed up fsync and gc scans, and started the slow march towards supporting filesystem shrinking. There's a huge refactoring of the internal speculative preallocation garbage collection code which fixes a bunch of bugs, makes the gc scheduling per-AG and hence multithreaded, and standardizes the retry logic when we try to reserve space or quota, can't, and want to trigger a gc scan. We also enable multithreaded quotacheck to reduce mount times further. This is also preparation for background file gc, which may or may not land for 5.13. We also fixed some deadlocks in the rename code, fixed a quota accounting leak when FSSETXATTR fails, restored the behavior that write faults to an mmap'd region actually cause a SIGBUS, fixed a bug where sgid directory inheritance wasn't quite working properly, and fixed a bug where symlinks weren't working properly in ecryptfs. We also now advertise the inode btree counters feature that was introduced two cycles ago. Summary: - Fix an ABBA deadlock when renaming files on overlayfs. - Make sure that we can't overflow the inode extent counters when adding to or removing extents from a file. - Make directory sgid inheritance work the same way as all the other filesystems. - Don't drain the buffer cache on freeze and ro remount, which should reduce the amount of time if read-only workloads are continuing during the freeze. - Fix a bug where symlink size isn't reported to the vfs in ecryptfs. - Disentangle log cleaning from log covering. This refactoring sets us up for future changes to the log, though for now it simply means that we can use covering for freezes, and cleaning becomes something we only do at unmount. - Speed up file fsyncs by reducing iolock cycling. - Fix delalloc blocks leaking when changing the project id fails because of input validation errors in FSSETXATTR. - Fix oversized quota reservation when converting unwritten extents during a DAX write. - Create a transaction allocation helper function to standardize the idiom of allocating a transaction, reserving blocks, locking inodes, and reserving quota. Replace all the open-coded logic for file creation, file ownership changes, and file modifications to use them. - Actually shut down the fs if the incore quota reservations get corrupted. - Fix background block garbage collection scans to not block and to actually clean out CoW staging extents properly. - Run block gc scans when we run low on project quota. - Use the standardized transaction allocation helpers to make it so that ENOSPC and EDQUOT errors during reservation will back out, invoke the block gc scanner, and try again. This is preparation for introducing background inode garbage collection in the next cycle. - Combine speculative post-EOF block garbage collection with speculative copy on write block garbage collection. - Enable multithreaded quotacheck. - Allow sysadmins to tweak the CPU affinities and maximum concurrency levels of quotacheck and background blockgc worker pools. - Expose the inode btree counter feature in the fs geometry ioctl. - Cleanups of the growfs code in preparation for starting work on filesystem shrinking. - Fix all the bloody gcc warnings that the maintainer knows about. :P - Fix a RST syntax error. - Don't trigger bmbt corruption assertions after the fs shuts down. - Restore behavior of forcing SIGBUS on a shut down filesystem when someone triggers a mmap write fault (or really, any buffered write)" * tag 'xfs-5.12-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (85 commits) xfs: consider shutdown in bmapbt cursor delete assert xfs: fix boolreturn.cocci warnings xfs: restore shutdown check in mapped write fault path xfs: fix rst syntax error in admin guide xfs: fix incorrect root dquot corruption error when switching group/project quota types xfs: get rid of xfs_growfs_{data,log}_t xfs: rename `new' to `delta' in xfs_growfs_data_private() libxfs: expose inobtcount in xfs geometry xfs: don't bounce the iolock between free_{eof,cow}blocks xfs: expose the blockgc workqueue knobs publicly xfs: parallelize block preallocation garbage collection xfs: rename block gc start and stop functions xfs: only walk the incore inode tree once per blockgc scan xfs: consolidate the eofblocks and cowblocks workers xfs: consolidate incore inode radix tree posteof/cowblocks tags xfs: remove trivial eof/cowblocks functions xfs: hide xfs_icache_free_cowblocks xfs: hide xfs_icache_free_eofblocks xfs: relocate the eofb/cowb workqueue functions xfs: set WQ_SYSFS on all workqueues in debug mode ... -

Pull iomap updates from Darrick Wong: "The big change in this cycle is some new code to make it possible for XFS to try unaligned directio overwrites without taking locks. If the block is fully written and within EOF (i.e. doesn't require any further fs intervention) then we can let the unlocked write proceed. If not, we fall back to synchronizing direct writes. Summary: - Adjust the final parameter of iomap_dio_rw. - Add a new flag to request that iomap directio writes return EAGAIN if the write is not a pure overwrite within EOF; this will be used to reduce lock contention with unaligned direct writes on XFS. - Amend XFS' directio code to eliminate exclusive locking for unaligned direct writes if the circumstances permit" * tag 'iomap-5.12-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: reduce exclusive locking on unaligned dio xfs: split the unaligned DIO write code out xfs: improve the reflink_bounce_dio_write tracepoint xfs: simplify the read/write tracepoints xfs: remove the buffered I/O fallback assert xfs: cleanup the read/write helper naming xfs: make xfs_file_aio_write_checks IOCB_NOWAIT-aware xfs: factor out a xfs_ilock_iocb helper iomap: add a IOMAP_DIO_OVERWRITE_ONLY flag iomap: pass a flags argument to iomap_dio_rw iomap: rename the flags variable in __iomap_dio_rw -

Pull fsverity updates from Eric Biggers: "Add an ioctl which allows reading fs-verity metadata from a file. This is useful when a file with fs-verity enabled needs to be served somewhere, and the other end wants to do its own fs-verity compatible verification of the file. See the commit messages for details. This new ioctl has been tested using new xfstests I've written for it" * tag 'fsverity-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt: fs-verity: support reading signature with ioctl fs-verity: support reading descriptor with ioctl fs-verity: support reading Merkle tree with ioctl fs-verity: add FS_IOC_READ_VERITY_METADATA ioctl fs-verity: don't pass whole descriptor to fsverity_verify_signature() fs-verity: factor out fsverity_get_descriptor()
