✨ AI-generated root cause summary:

In __sync_rcu_exp_select_node_cpus() (kernel/rcu/tree_exp.h), the expedited RCU grace period worker thread (rcu_exp_gp_kthr) iterates over non-idle online CPUs to request quiescent states using asynchronous IPIs via smp_call_function_single(..., wait=0). Asynchronous SMP calls reuse the sender CPU's per-CPU csd_data structure (kernel/smp.c), requiring subsequent iterations to spin in csd_lock() / csd_lock_wait() with preemption disabled until the previous target CPU dequeues the CSD and executes csd_unlock(). A remote CPU failed to service its call_single_queue within the watchdog period, causing CPU 0 to spin indefinitely in csd_lock_wait(). After exceeding watchdog_thresh without scheduling, watchdog_timer_fn() detected the softlockup and triggered a kernel panic.

Technical Breakdown and Root Cause Analysis

Involved Functions, Structs, and Files

  • __sync_rcu_exp_select_node_cpus() (kernel/rcu/tree_exp.h): Drives the expedited RCU quiescent-state selection across CPUs in a leaf rcu_node.
  • smp_call_function_single() / __smp_call_function_single() (kernel/smp.c): Enqueues function execution requests on specific target CPUs.
  • csd_lock() / csd_lock_wait() / csd_unlock() (kernel/smp.c): Manages acquisition and release of call_single_data_t instances.
  • __flush_smp_call_function_queue() (kernel/smp.c): Executes pending callbacks on the target CPU and unlocks asynchronous CSD structures.
  • watchdog_timer_fn() (kernel/watchdog.c): Detects CPU softlockup when a task fails to yield the CPU within watchdog_thresh.

Failure Mechanism and Invariant Violation

  1. Expedited Grace Period Quiescent State Selection: During an expedited RCU grace period, the dedicated worker kthread (rcu_exp_gp_kthr, PID 19) executes sync_rcu_exp_select_cpus() $\to$ __sync_rcu_exp_select_node_cpus(). For non-idle, online CPUs recorded in mask_ofl_ipi, the function dispatches IPIs requesting quiescent states by invoking:

    ret = smp_call_function_single(cpu, rcu_exp_handler, NULL, 0);

    with wait = 0 (asynchronous invocation).

  2. Per-CPU CSD Reuse and Invariant Serialization: When smp_call_function_single() is called asynchronously (wait == 0), it cannot use a stack-allocated CSD. In the default configuration (where CONFIG_CSD_LOCK_WAIT_DEBUG_DEFAULT is not enabled), get_single_csd_data() returns the calling CPU's per-CPU csd_data structure:

    csd = get_single_csd_data(cpu); // returns this_cpu_ptr(&csd_data)
csd_lock(csd);

    In csd_lock(), the sender must acquire CSD_FLAG_LOCK on this shared per-CPU structure. When sending multiple asynchronous IPIs sequentially in a loop across CPUs:

    • The first target CPU is enqueued the sender's per-CPU csd_data, which has CSD_FLAG_LOCK set.
    • When the loop advances to the next CPU and calls smp_call_function_single(next_cpu, ..., wait=0), it attempts to lock the sender's csd_data again.
    • It is forced to busy-wait in csd_lock_wait() (smp_cond_load_acquire(&csd->node.u_flags, !(VAL & CSD_FLAG_LOCK))) until the previous target CPU drains its call_single_queue in __flush_smp_call_function_queue() and executes csd_unlock().

  3. Disabled Preemption and Softlockup Detection: In __sync_rcu_exp_select_node_cpus(), preemption is held disabled across the invocation (get_cpu() at line 415 and within smp_call_function_single()). Because the remote target CPU failed to process its call_single_queue (due to prolonged interrupts-disabled sections or CPU stall), CPU 0 remained trapped in the csd_lock_wait() spin loop without scheduling.

  4. Panic Manifestation: After remaining continuously stuck on CPU 0 for longer than watchdog_thresh (configured to 55 seconds), the high-resolution timer interrupt invoked watchdog_timer_fn(). With softlockup_panic configured, the watchdog triggered sys_info() to dump the timer list and running tasks before halting the kernel with panic("softlockup: hung tasks"). Due to the high number of device kthreads configured (vivid.n_devs=64), the console buffer was overwhelmed, truncating the task listing before the higher-PID tasks running on the remote target CPUs could be output.
