[PATCH v4 0/8] lockdep: Change IRQ state tracking to use per-cpu variables

[PATCH v4 0/8] lockdep: Change IRQ state tracking to use per-cpu variables

[Peter Zijlstra]

Ahmed and Sebastian wanted additional lockdep_assert*() macros and ran into
header hell. I figured using per-cpu variables would cure that, and also
ran into header hell, still tracktable though.

By moving the IRQ state into per-cpu variables we remove the dependency on
task_struct.

Patches go on top of anything recent I think, an actual git tree with them
in is (for now) here:

  git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git locking/irqstate

Which 0day blessed with 0 build fails.

[PATCH v4 1/8] lockdep: Prepare for NMI IRQ state tracking

[Peter Zijlstra]

There is no reason not to always, accurately, track IRQ state.

This change also makes IRQ state tracking ignore lockdep_off().

[PATCH v4 2/8] x86/entry: Fix NMI vs IRQ state tracking

[Peter Zijlstra]

While the nmi_enter() users did
trace_hardirqs_{off_prepare,on_finish}() there was no matching
lockdep_hardirqs_*() calls to complete the picture.

Introduce idtentry_{enter,exit}_nmi() to enable proper IRQ state
tracking across the NMIs.

[PATCH v4 2/8] x86/entry: Fix NMI vs IRQ state tracking

[Peter Zijlstra]

While the nmi_enter() users did
trace_hardirqs_{off_prepare,on_finish}() there was no matching
lockdep_hardirqs_*() calls to complete the picture.

Introduce idtentry_{enter,exit}_nmi() to enable proper IRQ state
tracking across the NMIs.

[PATCH v4 4/8] powerpc64: Break asm/percpu.h vs spinlock_types.h dependency

[Peter Zijlstra]

In order to use <asm/percpu.h> in lockdep.h, we need to make sure
asm/percpu.h does not itself depend on lockdep.

The below seems to make that so and builds powerpc64-defconfig +
PROVE_LOCKING.

[PATCH v4 4/8] powerpc64: Break asm/percpu.h vs spinlock_types.h dependency

[Peter Zijlstra]

In order to use <asm/percpu.h> in lockdep.h, we need to make sure
asm/percpu.h does not itself depend on lockdep.

The below seems to make that so and builds powerpc64-defconfig +
PROVE_LOCKING.

If you define this unconditionally, then we can probably get rid of the
copy in asm/thread_info.h, rather than duplicate the same #define.

The below delta seems to build arm-allnoconfig, arm-defconfig and
arm-allmodconfig.

Although please don't ask me how asm/thread_info.h includes asm/percpu.h

Does that work for you?

[PATCH v4 7/8] lockdep: Change hardirq{s_enabled,_context} to per-cpu variables

[Peter Zijlstra]

Currently all IRQ-tracking state is in task_struct, this means that
task_struct needs to be defined before we use it.

Especially for lockdep_assert_irq*() this can lead to header-hell.

Move the hardirq state into per-cpu variables to avoid the task_struct
dependency.

[PATCH v4 7/8] lockdep: Change hardirq{s_enabled, _context} to per-cpu variables

[Peter Zijlstra]

Currently all IRQ-tracking state is in task_struct, this means that
task_struct needs to be defined before we use it.

Especially for lockdep_assert_irq*() this can lead to header-hell.

Move the hardirq state into per-cpu variables to avoid the task_struct
dependency.

Can we add a small comment on top of lockdep_off(), stating that lockdep
IRQ tracking will still be kept after a lockdep_off call?

That would only legitimize lockdep_off(). The only comment I want to put
on that is: "if you use this, you're doing it wrong'.

Well, freshly merged code is using it. For example, KCSAN:

    => f1bc96210c6a ("kcsan: Make KCSAN compatible with lockdep")
    => kernel/kcsan/report.c:

    void kcsan_report(...)
    {
	...
        /*
         * With TRACE_IRQFLAGS, lockdep's IRQ trace state becomes corrupted if
         * we do not turn off lockdep here; this could happen due to recursion
         * into lockdep via KCSAN if we detect a race in utilities used by
         * lockdep.
         */
        lockdep_off();

Marco, do you remember what exactly happened there? Because I'm about to
wreck that. That is, I'm going to make TRACE_IRQFLAGS ignore
lockdep_off().

Yeah, I was trying to squash any kind of recursion:

	lockdep -> other libs ->
		-> KCSAN
		-> print report
		-> dump stack, printk and friends
		-> lockdep -> other libs
			-> KCSAN ...

Some history:

* Initial patch to fix:
	https://lore.kernel.org/lkml/20200115162512.70807-1-elver@google.com/

* KCSAN+lockdep+ftrace:
	https://lore.kernel.org/lkml/20200214211035.209972-1-elver@google.com/

lockdep now has KCSAN_SANITIZE := n, but we still need to ensure that
there are no paths out of lockdep, or the IRQ flags tracing code, that
might lead through other libs, through KCSAN, libs used to generate a
report, and back to lockdep.

I never quite figured out the exact trace that led to corruption, but
avoiding any kind of potential for recursion was the only thing that
would avoid the check_flags() warnings.

That patch is weird; just :=n on lockdep.c should've cured that, the
rest is massive overkill.

Fair enough; I'll rip it all up and boot a KCSAN kernel, see what if

Thanks!

This was happening with Qian Cai's (Cc'd) test cases. If the kernel or
this patch changed things around so this doesn't happen anymore
regardless, then I don't see a problem.

Thanks!

This was happening with Qian Cai's (Cc'd) test cases. If the kernel or

I think I just hit a genuine but unavoidable lockdep report on
report_lock.

That appears to be warning about a lockdep_recursion underflow, weird.
I'll go stare at it.

OK, so the below patch doesn't seem to have any nasty recursion issues
here. The only 'problem' is that lockdep now sees report_lock can cause
deadlocks.

It is completely right about it too, but I don't suspect there's much we
can do about it, it's pretty much the standard printk() with scheduler
locks held report.

And I figured a quick way to get rid of that would be something like the
below, seeing how volatile gets auto annotated... but that doesn't seem
to actually work.

What am I missing?

There's one more in include/linux/rcupdate.h. I suggested this at some point:

    https://lore.kernel.org/lkml/20200220213317.GA35033@google.com/

To avoid volatiles as I don't think they are needed here.

There's one more in include/linux/rcupdate.h. I suggested this at some point:

    https://lore.kernel.org/lkml/20200220213317.GA35033@google.com/

To avoid volatiles as I don't think they are needed here.

[ Still testing your other patches for KCSAN, will send another reply there. ]

Urgghh.. local_t is very expensive for this. The current code is
actually fine, even on load-store architectures. Using local_t will only
result in it being more expensive for no gain.

I'll go put data_race() around it.

Right, I think we just have to tolerate the potential risk of deadlock
until there is a way to make all the code that prints in print_report()
scheduler-safe (that includes stack_trace_print()).

Based on your suggested change to core.c, how about the below patch?
Anything we've missed? If you think it's reasonable, please carry it
with the IRQ state tracking changes.

As far as I can tell there are no more warnings together with the other
patch you sent to add '& LOCKDEP_RECURSION_MASK'.

Thanks,

Subject: [PATCH] kcsan: Make KCSAN compatible with new IRQ state tracking

The new IRQ state tracking code does not honor lockdep_off(), and as
such we should again permit tracing by using non-raw functions in
core.c. Update the lockdep_off() comment in report.c, to reflect the
fact there is still a potential risk of deadlock due to using printk()
from scheduler code.

kcsan: Make KCSAN compatible with new IRQ state tracking

The new IRQ state tracking code does not honor lockdep_off(), and as
such we should again permit tracing by using non-raw functions in
core.c. Update the lockdep_off() comment in report.c, to reflect the
fact there is still a potential risk of deadlock due to using printk()
from scheduler code.

I think it would be nice to keep the "IRQs not disabled as expected"
message. It makes the lockdep splat much more readable.

This is similarly the case for the v3 lockdep preemption macros:

  https://lkml.kernel.org/r/20200630054452.3675847-5-a.darwish@linutronix.de

I did not add a message though to get in-sync with the IRQ macros above.

Thanks,

Hurmph.. the file:line output of a splat is usually all I look at, also
__WARN_printf() generates such atrocious crap code that try and not use
it.

I suppose I should do a __WARN_str() or something, but then people are
unlikely to want to use that, too much variation etc. :/

Cursed if you do, cursed if you don't.

lockdep: Change hardirq{s_enabled,_context} to per-cpu variables

Currently all IRQ-tracking state is in task_struct, this means that
task_struct needs to be defined before we use it.

Especially for lockdep_assert_irq*() this can lead to header-hell.

Move the hardirq state into per-cpu variables to avoid the task_struct
dependency.
