Currently, invoke rcu_tasks_rude_wait_gp() to wait one rude
RCU-tasks grace period, if __num_online_cpus == 1, will return
directly, indicates the end of the rude RCU-task grace period.
suppose the system has two cpus, consider the following scenario:
CPU0 CPU1 (going offline)
migration/1 task:
cpu_stopper_thread
-> take_cpu_down
-> _cpu_disable
(dec __num_online_cpus)
->cpuhp_invoke_callback
preempt_disable
access old_data0
task1
del old_data0 .....
synchronize_rcu_tasks_rude()
task1 schedule out
....
task2 schedule in
rcu_tasks_rude_wait_gp()
->__num_online_cpus == 1
->return
....
task1 schedule in
->free old_data0
preempt_enable
when CPU1 dec __num_online_cpus and __num_online_cpus is equal one,
the CPU1 has not finished offline, stop_machine task(migration/1)
still running on CPU1, maybe still accessing 'old_data0', but the
'old_data0' has freed on CPU0.
In order to prevent the above scenario from happening, this commit
remove check for __num_online_cpus == 0 and add handling of calling
synchronize_rcu_tasks_generic() during early boot(when the
rcu_scheduler_active variable is RCU_SCHEDULER_INACTIVE, the scheduler
not yet initialized and only one boot-CPU online).

Very good, thank you! I did the usual wordsmithing, including to that
error message, so as usual please check to make sure that I didn't mess
something up.

commit 033ddc5d337984e20b9d49c8af4faa4689727626
Author: Zqiang <qiang1.zhang@intel.com>
Date: Thu Dec 1 07:45:33 2022 +0800
rcu-tasks: Make rude RCU-Tasks work well with CPU hotplug
The synchronize_rcu_tasks_rude() function invokes rcu_tasks_rude_wait_gp()
to wait one rude RCU-tasks grace period. The rcu_tasks_rude_wait_gp()
function in turn checks if there is only a single online CPU. If so, it
will immediately return, because a call to synchronize_rcu_tasks_rude()
is by definition a grace period on a single-CPU system. (We could
have blocked!)
Unfortunately, this check uses num_online_cpus() without synchronization,
which can result in too-short grace periods. To see this, consider the
following scenario:
CPU0 CPU1 (going offline)
migration/1 task:
cpu_stopper_thread
-> take_cpu_down
-> _cpu_disable
(dec __num_online_cpus)
->cpuhp_invoke_callback
preempt_disable
access old_data0
task1
del old_data0 .....
synchronize_rcu_tasks_rude()
task1 schedule out
....
task2 schedule in
rcu_tasks_rude_wait_gp()
->__num_online_cpus == 1
->return
....
task1 schedule in
->free old_data0
preempt_enable
When CPU1 decrements __num_online_cpus, its value becomes 1. However,
CPU1 has not finished going offline, and will take one last trip through
the scheduler and the idle loop before it actually stops executing
instructions. Because synchronize_rcu_tasks_rude() is mostly used for
tracing, and because both the scheduler and the idle loop can be traced,
this means that CPU0's prematurely ended grace period might disrupt the
tracing on CPU1. Given that this disruption might include CPU1 executing
instructions in memory that was just now freed (and maybe reallocated),
this is a matter of some concern.
This commit therefore removes that problematic single-CPU check from the
rcu_tasks_rude_wait_gp() function. This dispenses with the single-CPU
optimization, but there is no evidence indicating that this optimization
is important. In addition, synchronize_rcu_tasks_generic() contains a
similar optimization (albeit only for early boot), which also splats.
(As in exactly why are you invoking synchronize_rcu_tasks_rude() so
early in boot, anyway???)
It is OK for the synchronize_rcu_tasks_rude() function's check to be
unsynchronized because the only times that this check can evaluate to
true is when there is only a single CPU running with preemption
disabled.
While in the area, this commit also fixes a minor bug in which a
call to synchronize_rcu_tasks_rude() would instead be attributed to
synchronize_rcu_tasks().

This is not a bug. this is caused by grace period taking too long time, the previous callback
has not been completed. from the dmesg, can be found that the cpuhotplug test is being
performed periodically, this may cause the rude RCU-Tasks grace period to take more time,
due to we need to acquire the cpus_read_lock, and the CPU0 always bootup failed, that is to
say, only one CPU of your system is online at this time.
Thanks

Onlining of a CPU failing with EIO is a new one on me. Especially
persistent failure.

I use the kernel configuration file in the attachment and base on:
https://git.kernel.org/cgit/linux/kernel/git/paulmck/linux-rcu.git dev
use "echo 1 > /sys/devices/system/cpu/cpu0/online" can reproduce this problem,
the CPU0 always fails to go online.
Debug found CPU0 is always not set in cpu_initialized_mask.
causes the do_boot_cpu() to return -1.
do_boot_cpu()
wakeup_cpu_via_init_nmi();
if (!boot_error) {
/*
* Wait 10s total for first sign of life from AP
*/
boot_error = -1;
timeout = jiffies + 10*HZ;
while (time_before(jiffies, timeout)) {
if (cpumask_test_cpu(cpu, cpu_initialized_mask)) {
/*
* Tell AP to proceed with initialization
*/
cpumask_set_cpu(cpu, cpu_callout_mask);
boot_error = 0;
break;
}
schedule();
}
}
This looks related to this modification e1c467e69040c("x86, hotplug:
Wake up CPU0 via NMI instead of INIT, SIPI, SIPI ").
The following modification can make CPU0 go online successfully(This
is just a test, not sure if there are other effects).

Thank you for tracking this down!!!
Huh. CPU 0 is normally the boot CPU. Back in the day, it could not
be offlined. Given that your testing indicates that CPU 0 can now be
taken offline, maybe this "if" statement is a holdover that someone
forgot to remove?
But I must defer to those who know a lot more about this level of
x86 code than I do.
Thanx, Paul

commit e1c467e69040c3be68959332959c07fb3d818e87
Author: Fenghua Yu <fenghua.yu@intel.com>
Date: Wed Nov 14 04:36:53 2012 -0800
x86, hotplug: Wake up CPU0 via NMI instead of INIT, SIPI, SIPI
Instead of waiting for STARTUP after INITs, BSP will execute the BIOS boot-strap
code which is not a desired behavior for waking up BSP. To avoid the boot-strap
code, wake up CPU0 by NMI instead.
This works to wake up soft offlined CPU0 only. If CPU0 is hard offlined (i.e.
physically hot removed and then hot added), NMI won't wake it up. We'll change
this code in the future to wake up hard offlined CPU0 if real platform and
request are available.
AP is still waken up as before by INIT, SIPI, SIPI sequence.

Interesting!
When I run rcutorture on x86 (under qemu/KVM), it refuses to attempt to
offline CPU 0. The reason is that cpu_is_hotpluggable(0) returns false.
If I comment out that check, I get this:
rcu-torture:torture_onoff task: offline 0 failed: errno -1
A bit of digging turned up the CONFIG_BOOTPARAM_HOTPLUG_CPU0 Kconfig
option. Setting that causes CPU 0 to be offlined.
I clearly need to add this to one of the scenarios. I arbitrarily
chose TREE01, but please let me know if some other scenario or
group of scenarios would be better.

commit 6c11be38a0363b61db36352555e6746920711a1f
Author: Paul E. McKenney <paulmck@kernel.org>
Date: Mon Jan 9 21:01:12 2023 -0800
rcutorture: Set CONFIG_BOOTPARAM_HOTPLUG_CPU0 to offline CPU 0
There is now a BOOTPARAM_HOTPLUG_CPU0 Kconfig option that allows CPU 0
to be offlined on x86 systems. This commit therefore sets this option in
the TREE01 rcutorture scenario in order to regularly test this capability.

You can use the kvm.sh --kconfig parameter to make this happen in your
own testing. Or you can hand-edit the TREE* files. The kvm.sh script
sets onoff_interval for you, so that should be OK. If you are testing
using modprobe, then yes, you need to set up this in your kernel build
and using the modprobe arguments.
It looks like x86 kernels build with CONFIG_BOOTPARAM_HOTPLUG_CPU0=n,
mostly, anyway, so most of the by-default rcutorture testing should also
build this way.
But again, you have a couple of ways to override this in your own testing.

And I cannot reproduce the CPU-hotplug online error under qemu/KVM.
Which might be expected behavior, given that you ran your tests using
specific qemu arguments that kvm.sh does not provide.
Nevertheless, CPU 0 really does go through the "Wake up BSP by nmi"
portion of wakeup_cpu_via_init_nmi() at runtime, and this works fine.
On the other hand, it also works fine if I comment out that "if (cpu)"
check.
This sounds like a question for your colleagues at Intel. ;-)

Hi Paul
After I enable the following options, CPU0 goes online successfully.
if the following options are disabled, CPU0 fails to go online.
(CONFIG_BOOTPARAM_HOTPLUG_CPU0 always enabled)
CONFIG_X86_X2APIC = y
CONFIG_X86_NUMACHIP = y
CONFIG_X86_UV = y
Thanks

Again, I must defer to people who know more about x86 than do I,
but should the BOOTPARAM_HOTPLUG_CPU0 Kconfig option select these?
The help text of some of them gives me pause, though.
For example, on CONFIG_X86_NUMACHIP, were you running a system with more
than 168 cores? For its part, CONFIG_X86_UV is supposed to be only for
the SGI Ultraviolet systems. I am not sure what conclusion to draw from
the CONFIG_X86_X2APIC help text. ;-)
Plus my runs don't have any of these three Kconfig options set. On the
other hand, I am running TREE01 on qemu/KVM with maxcpus=8 and nr_cpus=43,
so not a big system.
