kasan, arm64, scs, stacktrace: collect stack traces from Shadow Call Stack

Currently, KASAN always uses the normal stack trace collection routines,
which rely on the unwinder, when saving alloc and free stack traces.

Instead of invoking the unwinder, collect the stack trace by copying
frames from the Shadow Call Stack whenever it is enabled. This reduces
boot time by 30% for all KASAN modes when Shadow Call Stack is enabled.

Stack staces are collected from the Shadow Call Stack via a new
stack_trace_save_shadow() interface.

Note that the frame of the interrupted function is not included into
the stack trace, as it is not yet saved on the SCS when an interrupt
happens.

---

To deal with this last thing, we could save the interrupted frame address
in another per-CPU variable. I'll look into implementing this for v3.

I decided to postpone the changes to stack depot that avoid copying
frames twice until a planned upcoming update for stack depot.

Changes v1->v2:
- Provide a kernel-wide stack_trace_save_shadow() interface for collecting
  stack traces from shadow stack.
- Use ptrauth_strip_insn_pac() and READ_ONCE_NOCHECK, see the comments.
- Get SCS pointer from x18, as per-task value is meant to save the SCS
  value on CPU switches.
- Collect stack frames from SDEI and IRQ contexts.

Andrey Konovalov (4):
  stacktrace: add interface based on shadow call stack
  arm64, scs: save scs_sp values per-cpu when switching stacks
  arm64: implement stack_trace_save_shadow
  kasan: use stack_trace_save_shadow

[PATCH v2 1/4] stacktrace: add interface based on shadow call stack

[andrey.konovalov]

From: Andrey Konovalov <andreyknvl@google.com>

Add a new interface stack_trace_save_shadow() for collecting stack traces
by copying frames from the Shadow Call Stack.

Collecting stack traces this way is significantly faster: boot time
of a defconfig build with KASAN enabled gets descreased by ~30%.

The few patches following this one add an implementation of
stack_trace_save_shadow() for arm64.

The implementation of the added interface is not meant to use
stack_trace_consume_fn to avoid making a function call for each
collected frame to further improve performance.

[PATCH v2 2/4] arm64, scs: save scs_sp values per-cpu when switching stacks

[andrey.konovalov]

From: Andrey Konovalov <andreyknvl@google.com>

When an interrupt happens, the current Shadow Call Stack (SCS) pointer
is switched to a per-interrupt one stored in a per-CPU variable. The old
pointer is then saved on the normal stack and restored when the interrupt
is handled.

To collect the current stack trace based on SCS when the interrupt is
being handled, we need to know the SCS pointers that belonged to the
task and potentially other interrupts that were interrupted.

Instead of trying to retrieve the SCS pointers from the stack, change
interrupt handlers (for hard IRQ, Normal and Critical SDEI) to save the
previous SCS pointer in a per-CPU variable.

Note that interrupts stack. A task can be interrupted by a hard IRQ,
which then can interrupted by a normal SDEI, etc. This is handled by
using a separate per-CPU variable for each interrupt type.

Also reset the saved SCS pointer when exiting the interrupt. This allows
checking whether we should include any interrupt frames when collecting
the stack trace. While we could use in_hardirq(), there seems to be no
easy way to check whether we are in an SDEI handler. Directly checking
the per-CPU variables for being non-zero is more resilient.

Also expose both the the added saved SCS variables and the existing SCS
base variables in arch/arm64/include/asm/scs.h so that the stack trace
collection impementation can use them.

[PATCH v2 3/4] arm64: implement stack_trace_save_shadow

[andrey.konovalov]

From: Andrey Konovalov <andreyknvl@google.com>

Implement the stack_trace_save_shadow() interface that collects stack
traces based on the Shadow Call Stack (SCS) for arm64.

The implementation walks through available SCS pointers (the per-task one
and the per-interrupt-type ones) and copies the frames.

Note that the frame of the interrupted function is not included into
the stack trace, as it is not yet saved on the SCS when an interrupt
happens.

From: Andrey Konovalov <andreyknvl@google.com>

Now that stack_trace_save_shadow() is implemented by arm64, use it
whenever CONFIG_HAVE_SHADOW_STACKTRACE is enabled. This improves the
boot time of a defconfig build by ~30% for all KASAN modes.

That's fair.

Do any of these new changes introduce new (noticeable) overhead (in
particular patch 2)?

Why did this variable name change?

Would it be more reliable to check the return-code? I.e. do:

  int size;

  size = stack_trace_save_shadow(...)
  if (size < 0)
    size = stack_trace_save(...);

This is done deliberately to mimic stack_trace_save_tsk_reliable().
I'll mention this in the changelog.

My bad, I ran it on diff instead of the patch. Will fix in v3. Thanks!

So the lines below fit within one line. It won't be needed with the
other change you suggested.

Sounds good, will do in v3.

Hm, looks like the overhead is overly significant: ~5%. I'll explore a
different approach in v3 instead.

Hmm... just to check, do ou know if that's just because of hte linear copy, or
because we're skipping other work we have to do in the regular stacktrace?

... because we could easily provide an inline-optimized stack copy *without*
having to write a distinct unwinder, and I'd *really* like to avoid having a
bunch of distinct unwinders for arm64, as it really hinders maintenance. We're
working on fixing/improving the arm64 unwinder for things like
RELIABLE_STACKTRACE, and I know that some of that work is non-trivial to make
work with an SCS-based unwind rather than an FP-based unwind, and/or will
undermine the saving anyway.

If we really need this, can we make it an __always_inline in a header so that
we can avoid the skip? Generally the skipping is problematic due to
inlining/outlining and LTO, and I'd like to avoid adding more of it
unnecessarily.

I'm *really* not keen on *always* poking this in the entry code for the
uncommon case of unwind. It complicates the entry code and means we're always
paying a cost for potentially no benefit. At a high-level, I don't think this
is the right approach.

For the regular unwinder, I want to rework things such that we can identify
exception boundaries and look into the regs (e.g. so that we can recover the
PC+LR+FP and avoid duplicating part of this in a frame record), and I'd much
prefer that we did the same here.

Thanks,
Mark.

This doesn't do any of the trampoline repatinting (e.g. for kretprobes or
ftrace graph caller) that the regular unwinder does, so if either of those are
in use this is going to produce bogus results.

I really don't want to have to duplicate this logic.

This doesn't look necessary; it's certinaly not needed for the regular unwinder.

Critically, in the common case of unwinding just the task stack, we don't need
to look at any of the per-cpu stacks, and so there's no need to disable
preemption. See the stack nesting logic in the regular unwinder.

If we *do* need to unwind per-cpu stacks, we figure that out and verify our
countext *at* the transition point.

Does the compiler guarantee where this happens relative to any prologue
manipulation of x18?

This seems like something we should be using a compilar intrinsic for, or have
a wrapper that passes this in if necessary.

We have a number of portential stack nesting orders (and may need to introduce
more stacks in future), so I think we need to be more careful with this. The
regular unwinder handles that dynamically.

That is an impressive number. TBH, I'm shocked that this has *that* much of an
improvement, and I suspect this means we're doing something unnecssarily
expensive in the regular unwinder.

I've given some specific comments on patches, but a a high-level, I don't want
to add yet another unwind mechanism. For maintenance and correctness reasons,
we've spent the last few years consolidating various unwinders, which this
unfortunately goes against.

I see that there are number of cases this unwinder will fall afoul of (e.g.
kretprobes and ftrace graph trampolines), and making those work correctly will
require changes elsewhere (e.g. as we rely upon a snapshot of the FP to
disambiguate cases today).

I'm also very much not keen on having to stash things in the entry assembly for
this distinct unwinder.

Going forward, I'm also planning on making changes to the way we unwind across
exception boundaries (e.g. to report the LR and FP), and as that depends on
finding the pt_regs based on the FP, that's not going to work with SCS.

So at a high level, I don't want to add an SCS based unwinder.

However, I'm very much open to how we could improve the standard unwinder to be
faster, which would be more generally beneficial. I can see that there are some
things we could reasonably do with simple refactoring.

Thanks,
Mark.

I've had a quick look into this, to see what we could do to improve the regular
unwinder, but I can't reproduce that 30% number.

In local testing the worst can I could get to was 6-13% (with both the
stacktrace *and* stackdepot logic hacked out entirely).

I'm testing with clang 13.0.0 from the llvm.org binary releases, with defconfig
+ SHADOW_CALL_STACK + KASAN_<option>, using a very recent snapshot of mainline
(commit d888c83fcec75194a8a48ccd283953bdba7b2550). I'm booting a
KVM-accelerated QEMU VM on ThunderX2 with "init=/sbin/reboot -- -f" in the
kernel bootargs, timing the whole run from the outside with "perf stat --null".

The 6% figure is if I count boot as a whole including VM startup and teardown
(i.e. an under-estimate of the proportion), the 13% figure is if I subtract a
baseline timing from a run without KASAN (i.e. an over-estimate of the
proportion).

Could you let me know how you're measuring this, and which platform+config
you're using?

I'll have a play with some configs in case there's a pathological
configuration, but if you could let me know how/what you're testing that'd be a
great help.

Thanks,
Mark.

Do I understand correctly that kretprobes and ftrace modify frames
saved on SCS? So, if either is enabled, SCS frames might contain their
addresses instead of actual PCs?

If so, this is good enough for our use case. Having kretprobes or
ftrace enabled is an unusual setting and there's no requirement to
support it.

The goal is to have stack trace collection working in most cases
during a normal usage of an Android device. Being not feature-complete
and not covering all possible peculiar cases is fine.

I'll drop these changes, I'll respond on that patch.

The intention of adding an SCS-based unwinder it to use in production
together with MTE-based KASAN. Thus, it needs to be as fast as
possible. I doubt even a very optimized FP-based unwinder will compare
with a simple loop over SCS frames.

It seems a pity to let the kernel maintain the current call trace via
SCS and then not to use it to collect stack traces.

Would it be acceptable if we keep the SCS unwinder code in mm/kasan
and not integrate with the common stacktrace machanisms?

Thanks!

I think this is the reason for the limited improvement that you
observe. If you measure the time throughout VM startup and teardown,
you include the time required for userspace apps, which is irrelevant.

I measure boot time until a certain point during kernel boot. E.g.,
with the attached config, I measure the time until test_meminit start
running.

It takes 6 seconds for the kernel to reach test_meminit as is, and 4
seconds with kasan_save_stack() commented out. Only commenting out
__stack_depot_save() gives 5.9 seconds, so stack_trace_save() is the
slow part.

> Could you let me know how you're measuring this, and which platform+config

I've attached the config that I use. It's essentially defconfig + SCS
+ KASAN + maybe a few other options.

This also gives a 5% slowdown, which is not acceptable.

What we can do instead, is to not collect frames from the higher
exception levels at all. This would leave SCS-based stack collection
method impaired, but this is probably fine for KASAN's use case:
currently, stack depot filters out higher-level frames anyway, so
KASAN never saves them. And the lower-level part of the stack trace is
enough to identify the allocation.

Thanks!

Yes, I think this should work.

However, if we keep the implementation in mm/kasan, this integration
will not be required.

Thanks!

The common unwinder doesn't access per-cpu variables, so
preempt_disable() is not required.

Although, in this case, the per-cpu variable is read-only, so
preempt_disable() is probably also not required. Unless LOCKDEP or
some other tools complain about this.

I'm not sure I understand this statement. You mean we need to keep the
currently relevant SCS stack base and update it in interrupt handlers?
This will require modifying the entry code.

This is a good point, I'll investigate this.

I'll rewrite this part based on the other comments, so let's discuss it then.

Yes, that's the case for the 6% figure. However I also mentioned how I
accounted for that to get the 13% figure, which does not include those
irrelevant timings (and is an over-estimate of that proportion).

I think the discrepancy lies elsewhere, e.g. kernel version, boot arguments,
platform (and hence driver / subsystem behaviour), etc.

Can you share any of those details? Are you able to test with a mainline
kernel, e.g. v5.18-rc1?

I have a bunch of numbers below, and I think those imply one of the following:

* In your test setup, there are significantly more allocs/frees for which a
  stacktrace is being recorded. That could be down to the platform you're
  testing on, and the drivers that are in use.

* In your test setup, for some reason, some aspect of the stacktrace is
  signficantly more expensive than in my setup. There's the potential that a
  hardware quirk has some impact here, so knowing which hardware you're testing
  on would be very helpful.

* There is a secondary effect at play. There are a number of potential things
  here (e.g. console accesses, the number of stacktraces taken in interrupt
  context, etc).

I'd like to figure out which (if any) of those apply.

How exactly are you measuring the point at which test_meminit() starts running?
Are you looking through dmesg, or passing some debug options? I ask because
that doesn't seem to dump anything into dmesg until at least one test has run.

FWIW, I was measuring the kernel boot up-to the point we'd run the userspace
init program, by booting the kernel with:

	init=/sbin/reboot -- -f

... which I think is more representative of the full boot time.

I can instead avoid that by not passing a filesystem and booting with:

	panic=-1

... to trigger an instant reboot when we'd normally mount the filesystem, but
the numbers as similar either way for me.

I've followed the latter approach for my numbers below, since it's easier to
reproduce.

As above, how are you measuring this?

... and since your config has CONFIG_KASAN_KUNIT_TEST=y, which console
options (e.g. 'quiet', 'loglevel=') are you passing on the kernel command line?

I ask because in my local testing, that options results in a load of test
results being dumped to the console, and the time taken to do so dominates
everything else. Hacking out the stack sampling reduces the amount of data we
log to the console, and this secondary effect reduces boot time.

I'm afraid from local testing (atop v5.18-rc1), with your config, I still can't
get anywhere near your figures. I've tried to match toolchain versions with
what was in your .config file, so I'm using clang 12.0.0 from the llvm.org
binary releases, and binutils from the kernel.org crosstool 11.1.0 release.

I took baselines with defconfig and defconfig + SHADOW_CALL_STACK, with console
output completely suppressed with 'quiet loglevel=0':

Then I tried the same with your config, without your patches:

| [mark@gravadlaks:~/repro]% taskset -c 64 ./vmboot.sh --perf-trials 50 -s -k ~/kernel-images/andrey-unwind-v5.18-rc1-andrey.config/Image

Then with your config, without your patches, with the stacktrace hacked out:

| [mark@gravadlaks:~/repro]% taskset -c 64 ./vmboot.sh --perf-trials 50 -s -k ~/kernel-images/andrey-unwind-v5.18-rc1-andrey.config-nostacktrace/Image

If I use those number to estimate the proportion of time spent stacktracing,
with the baseline SCS number discounted to remove the hypervisor+VMM overheads,
I get:

	(1.994692366 - 0.523245952) - (1.861823869 - 0.523245952)
        ---------------------------------------------------------  = 0.09029788358
	(1.994692366 - 0.523245952)

So roughly 9% when I try to maximize that figure. When actually poking hardware
and doing real work, that figure goes down. For example, if just using "quiet":

Which gives an estimate of:

	(4.653286475 - 0.523245952) - (4.585750154 - 0.523245952)
	---------------------------------------------------------  = 0.01635245964
	(4.653286475 - 0.523245952)

... or ~1.6% time spent backtracing:

FWIW, applying your patches do show some benefit, but not as drastic as I was
expecting:

With console output suprressed:

| [mark@gravadlaks:~/repro]% taskset -c 64 ./vmboot.sh --perf-trials 50 -s -k ~/kernel-images/andrey-unwind-v5.18-rc1+scs-unwind-andrey.config/Image

... down from ~9% to ~4%

With console output merely reduced:

| [mark@gravadlaks:~/repro]% taskset -c 64 ./vmboot.sh --perf-trials 50 -q -k ~/kernel-images/andrey-unwind-v5.18-rc1+scs-unwind-andrey.config/Image > /dev/null

... down from 1.6% to 0.6%

Given the above I still think we need to understand this a bit better before we
consider pursuing the SCS unwinder, given the issues I laid out in my prior mails.

My hope is that we can improve the regular unwinder or other code such that
this becomes moot. I'm aware of a few things we could try, but given it's very
easy to sink a lot of time and effort into this, I'd like to first get some
more details, as above.

Thanks,
Mark.

Hi Mark,

I'm about to publish v3, where I'll include a detailed description of
how I measured the performance.

Perhaps we see different performance numbers because you're using
KVM-enabled VM on an Arm host and I'm using QEMU on x86-64 host.
Although, it's suspicious that the difference is so drastic. I'll try
to get my hands on some Arm hardware in the next few days and do the
measurements there.

This new version also will not be making any changes to the entry
code, as these changes add unwanted additional slowdown. That would be
great, if you could check the performance impact of v3 with your
setup.

Thanks!

Hold on; are you using QEMU in TCG mode? If so that's in no way representative
of real HW performance, and there are operations it simply cannot make as fast
as HW can (e.g. pointer authentication using the architected QARMA variants).

> Although, it's suspicious that the difference is so drastic.

I'm not surprised at all. Some operations can be *orders of magnitude slower*
under TCG than on real HW even when considered relative to other operations,
and this can drasticaly skew benchmarks. We recently hit a case when PACIASP
and AUTIASP were so slow under TCG mode they appeared to be causing a boot
hang, and we eventually figured out that they were just *very* slow, adding
minutes to the boot time. Richard Henderson added options to QEMU to mitigate
that (either disabling authentication, or using an IMPLEMENTATION DEFINED
algorithm).

The bottom line is that QEMU TCG mode is in no way representative of real-world
performance, and *cannot* be used for benchmarking.

I think we first need to understand *what* is so slow under QEMU TCG mode, and
*why* TCG mode performance matters. I suspect there are other ways we could
avoid this overhead *without* adding another unwinder, but even then we need a
justification for *why* we should care.

I'll take a look at the series, but as before I do not think we should add
another unwinder. As above, I *certainly* do not think we should add another
unwinder based on TCG performance.
