UPSTREAM: rcu: Apply RCU-bh QSes to RCU-sched and RCU-preempt when safe
One necessary step towards consolidating the three flavors of RCU is to make sure that the resulting consolidated "one flavor to rule them all" correctly handles networking denial-of-service attacks. One thing that allows RCU-bh to do so is that __do_softirq() invokes rcu_bh_qs() every so often, and so something similar has to happen for consolidated RCU. This must be done carefully. For example, if a preemption-disabled region of code takes an interrupt which does softirq processing before returning, consolidated RCU must ignore the resulting rcu_bh_qs() invocations -- preemption is still disabled, and that means an RCU reader for the consolidated flavor. This commit therefore creates a new rcu_softirq_qs() that is called only from the ksoftirqd task, thus avoiding the interrupted-a-preempted-region problem. This new rcu_softirq_qs() function invokes rcu_sched_qs(), rcu_preempt_qs(), and rcu_preempt_deferred_qs(). The latter call handles any deferred quiescent states. Note that __do_softirq() still invokes rcu_bh_qs(). It will continue to do so until a later stage of cleanup when the RCU-bh flavor is removed.

UPSTREAM: rcu: Defer reporting RCU-preempt quiescent states when disabled
This commit defers reporting of RCU-preempt quiescent states at rcu_read_unlock_special() time when any of interrupts, softirq, or preemption are disabled. These deferred quiescent states are reported at a later RCU_SOFTIRQ, context switch, idle entry, or CPU-hotplug offline operation. Of course, if another RCU read-side critical section has started in the meantime, the reporting of the quiescent state will be further deferred. This also means that disabling preemption, interrupts, and/or softirqs will act as an RCU-preempt read-side critical section. This is enforced by checking preempt_count() as needed. Some special cases must be handled on an ad-hoc basis, for example, context switch is a quiescent state even though both the scheduler and do_exit() disable preemption. In these cases, additional calls to rcu_preempt_deferred_qs() override the preemption disabling. Similar logic overrides disabled interrupts in rcu_preempt_check_callbacks() because in this case the quiescent state happened just before the corresponding scheduling-clock interrupt. In theory, this change lifts a long-standing restriction that required that if interrupts were disabled across a call to rcu_read_unlock() that the matching rcu_read_lock() also be contained within that interrupts-disabled region of code. Because the reporting of the corresponding RCU-preempt quiescent state is now deferred until after interrupts have been enabled, it is no longer possible for this situation to result in deadlocks involving the scheduler's runqueue and priority-inheritance locks. This may allow some code simplification that might reduce interrupt latency a bit. Unfortunately, in practice this would also defer deboosting a low-priority task that had been subjected to RCU priority boosting, so real-time-response considerations might well force this restriction to remain in place. Because RCU-preempt grace periods are now blocked not only by RCU read-side critical sections, but also by disabling of interrupts, preemption, and softirqs, it will be possible to eliminate RCU-bh and RCU-sched in favor of RCU-preempt in CONFIG_PREEMPT=y kernels. This may require some additional plumbing to provide the network denial-of-service guarantees that have been traditionally provided by RCU-bh. Once these are in place, CONFIG_PREEMPT=n kernels will be able to fold RCU-bh into RCU-sched. This would mean that all kernels would have but one flavor of RCU, which would open the door to significant code cleanup. Moving to a single flavor of RCU would also have the beneficial effect of reducing the NOCB kthreads by at least a factor of two. Signed-off-by: Paul E.

rcu: Print stall-warning NMI dyntick state in hexadecimal
The ->dynticks_nmi_nesting field records the nesting depth of both interrupt and NMI handlers. Because the kernel can enter interrupts and never leave them (and vice versa) and because NMIs can interrupt manipulation of the ->dynticks_nmi_nesting field, the values in this field must be both chosen and maniupated very carefully. As a result, although the value is zero when the corresponding CPU is executing neither an interrupt nor an NMI handler, it is 4,611,686,018,427,387,906 on 64-bit systems when there is a single level of interrupt/NMI handling in progress. This number is difficult to remember and interpret, so this commit switches the output to hexadecimal, resulting in the much nicer 0x4000000000000002. Signed-off-by: Paul E.

The rcu_preempt_qs() function only applies to the CPU, not the task.

rcu: Mark task as .need_qs less aggressively
If any scheduling-clock interrupt interrupts an RCU-preempt read-side critical section, the interrupted task's ->rcu_read_unlock_special.b.need_qs field is set. This causes the outermost rcu_read_unlock() to incur the extra overhead of calling into rcu_read_unlock_special(). This commit reduces that overhead by setting ->rcu_read_unlock_special.b.need_qs only if the grace period has been in effect for more than one second. Why one second? Because this is comfortably smaller than the minimum RCU CPU stall-warning timeout of three seconds, but long enough that the .need_qs marking should happen quite rarely. And if your RCU read-side critical section has run on-CPU for a full second, it is not unreasonable to invest some CPU time in ending the grace period quickly. Signed-off-by: Paul E.

rcu: Add CPU online/offline state to dump_blkd_tasks()
Interactions between CPU-hotplug operations and grace-period initialization can result in dump_blkd_tasks(). One of the first debugging actions in this case is to search back in dmesg to work out which of the affected rcu_node structure's CPUs are online and to determine the last CPU-hotplug operation affecting any of those CPUs. This can be laborious and error-prone, especially when console output is lost. This commit therefore causes dump_blkd_tasks() to dump the state of the affected rcu_node structure's CPUs and the last grace period during which the last offline and online operation affected each of these CPUs.

RCU should only be waiting on CPUs that were online at the time that the current grace period started.

rcu: Suppress false-positive splats from mid-init task resume
Consider the following sequence of events in a PREEMPT=y kernel: 1. All CPUs corresponding to a given leaf rcu_node structure are offline. 2. The first phase of the rcu_gp_init() function's grace-period initialization runs, and sets that rcu_node structure's ->qsmaskinit to zero, as it should. 3. One of the CPUs corresponding to that rcu_node structure comes back online. Note that because this CPU came online after the grace period started, this grace period can safely ignore this newly onlined CPU. 4. A task running on the newly onlined CPU enters an RCU-preempt read-side critical section, and is then preempted. Because the corresponding rcu_node structure's ->qsmask is zero, rcu_preempt_ctxt_queue() leaves the rcu_node structure's ->gp_tasks field NULL, as it should. 5. The rcu_gp_init() function continues running the second phase of grace-period initialization. The ->qsmask field of the parent of the aforementioned leaf rcu_node structure is set to not expect a quiescent state from the leaf, as is only right and proper. However, when rcu_gp_init() reaches the leaf, it invokes rcu_preempt_check_blocked_tasks(), which sees that the leaf's ->blkd_tasks list is non-empty, and therefore sets the leaf's ->gp_tasks field to reference the first task on that list. 6. The grace period ends before the preempted task resumes, which is perfectly fine, given that this grace period was under no obligation to wait for that task to exit its late-starting RCU-preempt read-side critical section. Unfortunately, the leaf's ->gp_tasks field is non-NULL, so rcu_gp_cleanup() splats. After all, it appears to rcu_gp_cleanup() that the grace period failed to wait for a task that was supposed to be blocking that grace period. This commit avoids this false-positive splat by adding a check of both ->qsmaskinit and ->wait_blkd_tasks to rcu_preempt_check_blocked_tasks(). If both ->qsmaskinit and ->wait_blkd_tasks are zero, then the task must have entered its RCU-preempt read-side critical section late (after all, the CPU that it is running on was not online at that time), which means that the upper-level rcu_node structure won't be waiting for anything on the leaf anyway. If ->wait_blkd_tasks is non-zero, then there is at least one task on ths rcu_node structure's ->blkd_tasks list whose RCU read-side critical section predates the current grace period. If ->qsmaskinit is non-zero, there is at least one CPU that was online at the start of the current grace period. Thus, if both are zero, there is nothing to wait for. Signed-off-by: Paul E.

This commit makes rcu_nocb_wait_gp() check rdp->gp_seq_needed to see if the current CPU already knows about the needed grace period having already been requested. If so, it avoids acquiring the corresponding leaf rcu_node structure's ->lock, thus decreasing contention.

rcu: Convert grace-period requests to ->gp_seq
This commit converts the grace-period request code paths from ->completed and ->gpnum to ->gp_seq. The need_future_gp_element() macro encapsulates the shift operation required to use ->gp_seq as an index to the ->need_future_gp[] array. The rcu_cbs_completed() function is removed in favor of the rcu_seq_snap() function. The rcu_start_this_gp() gets some temporary consistency checks and uses rcu_seq_done(), rcu_seq_current(), rcu_seq_state(), and rcu_gp_in_progress() in place of the earlier open-coded comparisons of ->gpnum and ->completed. The rcu_future_gp_cleanup() function replaces use of ->completed with ->gp_seq. The rcu_accelerate_cbs() function replaces a call to rcu_cbs_completed() with one to rcu_seq_snap(). The rcu_advance_cbs() function replaces an access to >completed with one to ->gp_seq and adds some temporary warnings. The rcu_nocb_wait_gp() function replaces a call to rcu_cbs_completed() with one to rcu_seq_snap() and an open-coded comparison with rcu_seq_done(). The temporary warnings will be removed when the various ->gpnum and ->completed fields are removed. Their purpose is to locate code who might still be using ->gpnum and ->completed.

rcu: Make rcu_start_future_gp() caller select grace period
The rcu_accelerate_cbs() function selects a grace-period target, which it uses to have rcu_segcblist_accelerate() assign numbers to recently queued callbacks. Then it invokes rcu_start_future_gp(), which selects a grace-period target again, which is a bit pointless. This commit therefore changes rcu_start_future_gp() to take the grace-period target as a parameter, thus avoiding double selection. This commit also changes the name of rcu_start_future_gp() to rcu_start_this_gp() to reflect this change in functionality, and also makes a similar change to the name of trace_rcu_future_gp().

rcu: Make rcu_gp_cleanup() more accurately predict need for new GP
Currently, rcu_gp_cleanup() scans the rcu_node tree in order to reset state to reflect the end of the grace period. It also checks to see whether a new grace period is needed, but in a number of cases, rather than directly cause the new grace period to be immediately started, it instead leaves the grace-period-needed state where various fail-safes can find it. This works fine, but results in higher contention on the root rcu_node structure's ->lock, which is undesirable, and contention on that lock has recently become noticeable. This commit therefore makes rcu_gp_cleanup() immediately start a new grace period if there is any need for one. It is quite possible that it will later be necessary to throttle the grace-period rate, but that can be dealt with when and if. Reported-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Paul E.

To improve maintainability, this commit adds need_future_gp_mask() to compute the indexing mask from the array size, need_future_gp_element() to access the element corresponding to the specified grace-period number, and need_any_future_gp() to determine if any future grace period is needed. This commit also applies need_future_gp_element() to existing open-coded single-element accesses. Signed-off-by: Paul E.

rcu: Add leaf-node macros
This commit adds rcu_first_leaf_node() that returns a pointer to the first leaf rcu_node structure in the specified RCU flavor and an rcu_is_leaf_node() that returns true iff the specified rcu_node structure is a leaf. This commit also uses these macros where appropriate. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Tested-by: Nicholas Piggin <npiggin@gmail.com> |

rcu: Update rcu_bind_gp_kthread() header comment
The header comment for rcu_bind_gp_kthread() refers to sysidle, which is no longer with us. However, it is still important to bind RCU's grace-period kthreads to the housekeeping CPU(s), so rather than remove rcu_bind_gp_kthread(), this commit updates the comment. Signed-off-by: Paul E.

rcu: Move __rcu_read_lock() and __rcu_read_unlock() to tree_plugin.h
The __rcu_read_lock() and __rcu_read_unlock() functions were moved to kernel/rcu/update.c in order to implement tiny preemptible RCU. However, tiny preemptible RCU was removed from the kernel a long time ago, so this commit belatedly moves them back into the only remaining preemptible-RCU code. Signed-off-by: Paul E.

rcu: Call wake_nocb_leader_defer() with 'FORCE' when nocb_q_count is high
If an excessive number of callbacks have been queued, but the NOCB leader kthread's wakeup must be deferred, then we should wake up the leader unconditionally once it is safe to do so. This was handled correctly in commit |

rcu: Remove obsolete callback-invocation statistics for debugfs
The debugfs interface displayed statistics on RCU callback invocation but this interface has since been removed. This commit therefore removes the no-longer-used rcu_data structure's ->n_cbs_invoked and ->n_nocbs_invoked fields along with their updates. If this information proves necessary in the future, the corresponding event traces will be added. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> |

rcu: Call touch_nmi_watchdog() while printing stall warnings
When RCU stall warning triggers, it can print out a lot of messages while holding spinlocks.

rcu: Fix CPU offload boot message when no CPUs are offloaded
In CONFIG_RCU_NOCB_CPU=y kernels, if the boot parameters indicate that none of the CPUs should in fact be offloaded, the following somewhat obtuse message appears: Offload RCU callbacks from CPUs: . This commit therefore makes the message at least grammatically correct in this case: Offload RCU callbacks from CPUs: (none) Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> |

rcu: Remove have_rcu_nocb_mask from tree_plugin.h
Currently have_rcu_nocb_mask is used to avoid double allocation of rcu_nocb_mask during boot up. Due to different representation of cpumask_var_t on different kernel config CPUMASK=y(or n) it was okay. But now we have a helper cpumask_available(), which can be utilized to check whether rcu_nocb_mask has been allocated or not without using a variable. Removing the variable also reduces vmlinux size.

rcu: Shrink ->dynticks_{nmi_,}nesting from long long to long
Because the ->dynticks_nesting field now only contains the process-based nesting level instead of a value encoding both the process nesting level and the irq "nesting" level, we no longer need a long long, even on 32-bit systems. This commit therefore changes both the ->dynticks_nesting and ->dynticks_nmi_nesting fields to long. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> |
