[PATCH v3] lib: stackdepot: Add support to configure STACK_HASH_SIZE

[PATCH v3] lib: stackdepot: Add support to configure STACK_HASH_SIZE

[vjitta]

From: Yogesh Lal <ylal@codeaurora.org>

Add a kernel parameter stack_hash_order to configure STACK_HASH_SIZE.

Aim is to have configurable value for STACK_HASH_SIZE, so that one
can configure it depending on usecase there by reducing the static
memory overhead.

One example is of Page Owner, default value of STACK_HASH_SIZE lead
stack depot to consume 8MB of static memory. Making it configurable
and use lower value helps to enable features like CONFIG_PAGE_OWNER
without any significant overhead.

Can we go with a static CONFIG_ parameter instead?
Guess most users won't bother changing the default anyway, and for
CONFIG_PAGE_OWNER users changing the size at boot time is not strictly
needed.

Please initialize with MAX_STACK_HASH_ORDER instead.

Looks like you are assuming stack_table_def already contains some data
by this point.
But if STACK_HASH_SIZE shrinks this memcpy() above will just copy some
part of the table, whereas the rest will be lost.
We'll need to:
- either explicitly decide we can afford losing this data (no idea how
bad this can potentially be),
- or disallow storing anything prior to full stackdepot initialization
(then we don't need stack_table_def),
- or carefully move all entries to the first part of the table.

Thanks for review.

One advantage of having run time parameter is we can simply set it to a
lower value at runtime if page_owner=off thereby reducing the memory
usage or use default value if we want to use page owner so, we have some
some flexibility here. This is not possible with static parameter as we
have to have some predefined value.

The hash for stack_table_def is computed using the run time parameter
stack_hash_order, though stack_table_def is a bigger array it will only
use the entries that are with in the run time configured STACK_HASH_SIZE
range. so, there will be no data loss during copy.

If we are talking about a configuration in which page_owner is the
only stackdepot user in the system, then for page_owner=off it
probably makes more sense to disable stackdepot completely instead of
setting it to a lower value. This is a lot easier to do in terms of
correctness.
But if there are other users (e.g. KASAN), their stackdepot usage may
actually dominate that of page_owner.

Do we expect any data to be stored into stack_table_def before
setup_stack_hash_order() is called?
If the answer is no, then we could probably drop stack_table_def and
allocate the table right in setup_stack_hash_order()?

Yes, we do see an allocation from stack depot even before init is called
from kasan, thats the reason for having stack_table_def.
This is the issue reported due to that on v2, so i added stack_table_def.

But at that point STACK_HASH_SIZE is still equal to 1L <<
MAX_STACK_HASH_ORDER, isn't it?
Then we still need to take care of the records that fit into the
bigger array, but not the smaller one.

At this point early_param is already called which sets stack_hash_order.
So, STACK_HASH_SIZE will be set to this updated value and not
MAX_STACK_HASH_SIZE.So, no additional entires in the bigger array.

[-- Attachment #1: Type: text/plain, Size: 5104 bytes --]

Greeting,

FYI, we noticed the following commit (built with gcc-9):

commit: 1333d0ba67aa139cd33d20039e3a1dd9c79ec546 ("[PATCH v3] lib: stackdepot: Add support to configure STACK_HASH_SIZE")
url: https://github.com/0day-ci/linux/commits/vjitta-codeaurora-org/lib-stackdepot-Add-support-to-configure-STACK_HASH_SIZE/20201210-130554
base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git a2f5ea9e314ba6778f885c805c921e9362ec0420

in testcase: locktorture
version: 
with following parameters:

	runtime: 300s
	test: default

test-description: This torture test consists of creating a number of kernel threads which acquire the lock and hold it for specific amount of time, thus simulating different critical region behaviors.
test-url: https://www.kernel.org/doc/Documentation/locking/locktorture.txt

I still think there are implicit assumptions that should at least be
written down in the comments.
As far as I understand the code, here is what happens here:

0. No stacks are recorded.
1. early_param is called to set stack_hash_order to a value
potentially smaller than MAX_STACK_HASH_SIZE.
2. KASAN (or other users) records some stacks into stack_table_def
(capped at new STACK_HASH_SIZE)
3. init_stackdepot() allocates a new stack_table and copies the
contents of stack_table_def into it
4. Further stacks are recorded into the new stack_table

If this is how the things work, I agree we don't need to account for
the part of stack_table_def past STACK_HASH_SIZE.
Not allocating stack_table when setting stack_hash_order is probably
also justified, as we don't have SLAB or vmalloc at that point.

But I am still curious if a runtime parameter that disables the
stackdepot completely will solve your problem.
Allocating a small amount of memory when you actually don't want to
allocate any sounds suboptimal.

I think disabling stack depot completely should be fine, we can make
STACK_HASH_SIZE as runtime parameter instead of stack_hash_order and set
stack_hash_size to 0 to disable stack depot completely.

Minchan,
This should be fine right ? Do you see any issue with disabling
stack depot completely ?

To reiterate, I think you don't need a tunable stack_hash_order
parameter if the only use case is to disable the stack depot.
Maybe it is enough to just add a boolean flag?
Or even go further and disable the stack depot in the same place that
disables page owner, as the user probably doesn't want to set two
flags instead of one?

There are multiple users of stackdepot they might still want to use
stack depot but with a lower memory footprint instead of MAX_SIZE
so, a configurable size might help here ?

Since, page owner is not the only user of stack depot we can't take that
decision of disabling stack depot if page owner is disabled.

Can you provide an example of a use case in which the user wants to
use the stack depot of a smaller size without disabling it completely,
and that size cannot be configured statically?
As far as I understand, for the page owner example you gave it's
sufficient to provide a switch that can disable the stack depot if
page_owner=off.

Agreed, but if multiple subsystems want to use stackdepot together, it
is even harder to estimate the total memory consumption.
How likely is it that none of them will need MAX_SIZE?

There are two use cases here,

1. We don't want to consume memory when page_owner=off ,boolean flag
would work here.

2. We would want to enable page_owner on low ram devices but we don't
want stack depot to consume 8 MB of memory, so for this case we would
need a configurable stack_hash_size so that we can still use page_owner
with lower memory consumption.

So, a configurable stack_hash_size would work for both these use cases,
we can set it to '0' for first case and set the required size for the
second case.

Can interrupts happen at this point in time? If yes, they can

Will a combined solution with a boolean boot-time flag and a static
CONFIG_STACKDEPOT_HASH_SIZE work for these cases?
I suppose low-memory devices have a separate kernel config anyway?

My concern is that exposing yet another knob to users won't really
solve their problems, because the hash size alone doesn't give enough
control over stackdepot memory footprint (we also have stack_slabs,
which may get way bigger than 8Mb).

Yes, the combined solution will also work but i think having a single
run time config is simpler instead of having two things to configure.

True, stack_slabs can consume more memory but they consume most only
when stack depot is used as they are allocated in stack_depot_save path.
when stack depot is not used they consume 8192 * sizeof(void) bytes at
max. So nothing much we can do here since static allocation is not much
and memory consumption depends up on stack depot usage, unlike
stack_hash_table where 8mb is preallocated.

To add to it we started of with a CONFIG first, after the comments from
Minchan (https://lkml.org/lkml/2020/11/3/2121) we decided to switch to
run time param.

Quoting Minchan's comments below:

"
1. When we don't use page_owner, we don't want to waste any memory for
stackdepot hash array.
2. When we use page_owner, we want to have reasonable stackdeport hash array

With this configuration, it couldn't meet since we always need to
reserve a reasonable size for the array.
Can't we make the hash size as a kernel parameter?
With it, we could use it like this.

1. page_owner=off, stackdepot_stack_hash=0 -> no more wasted memory
when we don't use page_owner
2. page_owner=on, stackdepot_stack_hash=8M -> reasonable hash size
when we use page_owner.
"

Minchan, what do you think about making the hash size itself a static
parameter, while letting the user disable stackdepot completely at
runtime?
As noted before, I am concerned that moving a low-level configuration
bit (which essentially means "save 8Mb - (1 << stackdepot_stack_hash)
of static memory") to the boot parameters will be unused by most
admins and may actually trick them into thinking they reduce the
overall stackdepot memory consumption noticeably.
I also suppose device vendors may prefer setting a fixed (maybe
non-default) hash size for low-memory devices rather than letting the
admins increase it.

PS. Sorry for being late to the party, I should have probably spoken
up in November, when you've been discussing the first version of this
patch.

I am totally fine if we could save the static memory alloation when
the page_owner is not used.

IOW, page_owner=disable, stackdepot=disable will not consume the 8M
memory.
When we want to use page_owner, we could just do like this

	page_owner=enable, stackdepot=enable

(Maybe we need something to make warning if stackdepot is disabled
but someone want to use it, for example, KASAN?)

Vijayanand, If we could work this this, should we still need the
config option, then?

Michan, We would still need config option so that we can reduce the
memory consumption on low ram devices using config.

Alex, On this,
"I also suppose device vendors may prefer setting a fixed (maybe
non-default) hash size for low-memory devices rather than letting the
admins increase it."
I see kernel param swiotlb does similar thing i.e; '0' to disable and
set a value to configure size.

I am fine with either of the approaches,

1. I can split this patch into two
   i)  A bool variable to enable/disable stack depot.
   ii) A config for the size.

(or)

2. A run time param - '0' to disable and set a valid size to enable.

Let me know your comments.

I still believe this is a more appropriate solution.

Thanks in advance!
