[PATCH] blkcg: allocate struct blkcg_gq outside request queue spinlock

[PATCH] blkcg: allocate struct blkcg_gq outside request queue spinlock

[Tahsin Erdogan]

blkg_conf_prep() currently calls blkg_lookup_create() while holding
request queue spinlock. This means allocating memory for struct
blkcg_gq has to be made non-blocking. This causes occasional -ENOMEM
failures in call paths like below:

  pcpu_alloc+0x68f/0x710
  __alloc_percpu_gfp+0xd/0x10
  __percpu_counter_init+0x55/0xc0
  cfq_pd_alloc+0x3b2/0x4e0
  blkg_alloc+0x187/0x230
  blkg_create+0x489/0x670
  blkg_lookup_create+0x9a/0x230
  blkg_conf_prep+0x1fb/0x240
  __cfqg_set_weight_device.isra.105+0x5c/0x180
  cfq_set_weight_on_dfl+0x69/0xc0
  cgroup_file_write+0x39/0x1c0
  kernfs_fop_write+0x13f/0x1d0
  __vfs_write+0x23/0x120
  vfs_write+0xc2/0x1f0
  SyS_write+0x44/0xb0
  entry_SYSCALL_64_fastpath+0x18/0xad

In the code path above, percpu allocator cannot call vmalloc() due to
queue spinlock.

A failure in this call path gives grief to tools which are trying to
configure io weights. We see occasional failures happen shortly after
reboots even when system is not under any memory pressure. Machines
with a lot of cpus are more vulnerable to this condition.

Do struct blkcg_gq allocations outside the queue spinlock to allow blocking
during memory allocations.

Hello,

Overall, the approach looks good to me but please see below.

Pulling this out of the queue_lock doesn't seem safe to me.  This
function may end up calling into callbacks of disabled policies this
way.

Hmm... how about adding @new_blkg to blkg_lookup_create() and calling
it with non-NULL @new_blkg until it succeeds?  Wouldn't that be
simpler?

than duplicating the same logic here?

I will move this to within the lock. To make things safe, I am also
thinking of rechecking both blkcg_policy_enabled()  and
blk_queue_bypass() after reacquiring the locks in each iteration.

The challenge with that approach is creating a new_blkg with the right
blkcg before passing to blkg_lookup_create(). blkg_lookup_create()
walks down the hierarchy and will try to fill the first missing entry
and the preallocated new_blkg must have been created with the right
blkcg (feel free to send a code fragment if you think I am
misunderstanding the suggestion).

Ah, indeed, but we can break out allocation of blkg and its
initialization, right?  It's a bit more work but then we'd be able to
do something like.


retry:
	new_blkg = alloc;
	lock;
	sanity checks;
	blkg = blkg_lookup_and_create(..., new_blkg);
	if (!blkg) {
		unlock;
		goto retry;
	}

Thanks.

Add a flag to blkg_lookup_create() to indicate whether releasing locks
for memory allocation purposes is okay.

I tried doing it based on the sample above but I wasn't happy with the
result. The amount of code grew too big. I sent a simplified version
that does blkg allocation within blkg_lookup_create(). I think this
version is simpler, let me know what you think.

I'm okay with this direction but it probably would be better if the
parameter is gfp_mask and we branch on __GFP_WAIT in the function.

So, while I'm okay with the approach, now we're creating a hybrid
approach where we have both pre-allocation and allocation mode
altering mechanisms.  If we're going to take this route, I think the
right thing to do is passing down @gfp_mask all the way down to
blkg_create().

And let blkg_create() verify these conditions after releasing and
regrabbing the lock.

This also means that the init path can simply pass in GFP_KERNEL.

Agreed, gfp mask is better as a parameter.

I tried that approach, but I encountered two issues that complicate things:

1) Pushing down blk_queue_bypass(q) check in blkg_create() doesn't
quite work because when blkcg_init_queue() calls blkg_create(), the
queue is still in bypassing mode.

2) Pushing down blkcg_policy_enabled() doesn't work well either,
because blkcg_init_queue() doesn't have a policy to pass down. We
could let it pass a NULL parameter but that would make blkg_create
more ugly.

I see.  It kinda really bothers me that we'll have two different modes
for non-atomic allocations.  Can't we bind both to the policy
parameter?  Skip the checks if policy is NULL?

Thanks.

[PATCH v3] blkcg: allocate struct blkcg_gq outside request queue spinlock

[Tahsin Erdogan]

blkg_conf_prep() currently calls blkg_lookup_create() while holding
request queue spinlock. This means allocating memory for struct
blkcg_gq has to be made non-blocking. This causes occasional -ENOMEM
failures in call paths like below:

  pcpu_alloc+0x68f/0x710
  __alloc_percpu_gfp+0xd/0x10
  __percpu_counter_init+0x55/0xc0
  cfq_pd_alloc+0x3b2/0x4e0
  blkg_alloc+0x187/0x230
  blkg_create+0x489/0x670
  blkg_lookup_create+0x9a/0x230
  blkg_conf_prep+0x1fb/0x240
  __cfqg_set_weight_device.isra.105+0x5c/0x180
  cfq_set_weight_on_dfl+0x69/0xc0
  cgroup_file_write+0x39/0x1c0
  kernfs_fop_write+0x13f/0x1d0
  __vfs_write+0x23/0x120
  vfs_write+0xc2/0x1f0
  SyS_write+0x44/0xb0
  entry_SYSCALL_64_fastpath+0x18/0xad

In the code path above, percpu allocator cannot call vmalloc() due to
queue spinlock.

A failure in this call path gives grief to tools which are trying to
configure io weights. We see occasional failures happen shortly after
reboots even when system is not under any memory pressure. Machines
with a lot of cpus are more vulnerable to this condition.

Update blkg_create() function to temporarily drop the rcu and queue
locks when it is allowed by gfp mask.

v3:
  Pushed down all blkg allocations into blkg_create()

v2:
  Moved blkg creation into blkg_lookup_create() to avoid duplicating
  blkg_lookup_create() logic.

I'm not sure this error handling logic is correct.  We can have any

Heh, this seems a bit too fragile.  I get that this covers both call
paths into lookup_create which needs the checking, but it seems a bit
too nasty to do it this way.  Would it be ugly if we factor out both
policy enabled and bypass tests into a helper and have inner
__blkg_lookup_create() which skips it?  We can call the same helper
from blkg_create() when @pol.  Sorry that this is involving so much
bikeshedding.

Thanks!

[PATCH v4] blkcg: allocate struct blkcg_gq outside request queue spinlock

[Tahsin Erdogan]

blkg_conf_prep() currently calls blkg_lookup_create() while holding
request queue spinlock. This means allocating memory for struct
blkcg_gq has to be made non-blocking. This causes occasional -ENOMEM
failures in call paths like below:

  pcpu_alloc+0x68f/0x710
  __alloc_percpu_gfp+0xd/0x10
  __percpu_counter_init+0x55/0xc0
  cfq_pd_alloc+0x3b2/0x4e0
  blkg_alloc+0x187/0x230
  blkg_create+0x489/0x670
  blkg_lookup_create+0x9a/0x230
  blkg_conf_prep+0x1fb/0x240
  __cfqg_set_weight_device.isra.105+0x5c/0x180
  cfq_set_weight_on_dfl+0x69/0xc0
  cgroup_file_write+0x39/0x1c0
  kernfs_fop_write+0x13f/0x1d0
  __vfs_write+0x23/0x120
  vfs_write+0xc2/0x1f0
  SyS_write+0x44/0xb0
  entry_SYSCALL_64_fastpath+0x18/0xad

In the code path above, percpu allocator cannot call vmalloc() due to
queue spinlock.

A failure in this call path gives grief to tools which are trying to
configure io weights. We see occasional failures happen shortly after
reboots even when system is not under any memory pressure. Machines
with a lot of cpus are more vulnerable to this condition.

Update blkg_create() function to temporarily drop the rcu and queue
locks when it is allowed by gfp mask.

v4:
  Simplified error checking in blkg_create()
  Factored out __blkg_lookup_create()

v3:
  Pushed down all blkg allocations into blkg_create()

v2:
  Moved blkg creation into blkg_lookup_create() to avoid duplicating
  blkg_lookup_create() logic.

I have added a __blkg_lookup_create() and moved queue bypass check to
blkg_lookup_create(). This probably doesn't cover all your points but
I hope it is going towards the right direction. Do you still think we
need a helper function for policy/queue bypass checks?

[PATCH v5] blkcg: allocate struct blkcg_gq outside request queue spinlock

[Tahsin Erdogan]

blkg_conf_prep() currently calls blkg_lookup_create() while holding
request queue spinlock. This means allocating memory for struct
blkcg_gq has to be made non-blocking. This causes occasional -ENOMEM
failures in call paths like below:

  pcpu_alloc+0x68f/0x710
  __alloc_percpu_gfp+0xd/0x10
  __percpu_counter_init+0x55/0xc0
  cfq_pd_alloc+0x3b2/0x4e0
  blkg_alloc+0x187/0x230
  blkg_create+0x489/0x670
  blkg_lookup_create+0x9a/0x230
  blkg_conf_prep+0x1fb/0x240
  __cfqg_set_weight_device.isra.105+0x5c/0x180
  cfq_set_weight_on_dfl+0x69/0xc0
  cgroup_file_write+0x39/0x1c0
  kernfs_fop_write+0x13f/0x1d0
  __vfs_write+0x23/0x120
  vfs_write+0xc2/0x1f0
  SyS_write+0x44/0xb0
  entry_SYSCALL_64_fastpath+0x18/0xad

In the code path above, percpu allocator cannot call vmalloc() due to
queue spinlock.

A failure in this call path gives grief to tools which are trying to
configure io weights. We see occasional failures happen shortly after
reboots even when system is not under any memory pressure. Machines
with a lot of cpus are more vulnerable to this condition.

Update blkg_create() function to temporarily drop the rcu and queue
locks when it is allowed by gfp mask.

v5:
  Removed stale blkg_alloc() in blkcg_init_queue()

  Pushed down radix_tree_preload() into blkg_create() because it
  disables preemption on return and makes it unsafe to call blocking
  memory allocations.

v4:
  Simplified error checking in blkg_create()
  Factored out __blkg_lookup_create()

v3:
  Pushed down all blkg allocations into blkg_create()

v2:
  Moved blkg creation into blkg_lookup_create() to avoid duplicating
  blkg_lookup_create() logic.

I have a general dislike for code like that, where you conditionally
drop locks. And this one seems even worse, since the knowledge of
whether the locks should/could be dropped or not is embedded in the gfp
flags.

This seems problematic, as blkcg_bio_issue_check() calls with the rcu
read lock held.

Talked to Tejun about this as well, and we both agree that the splitting
this into separate init/alloc paths would be much cleaner. I can't
apply the current patch, sorry, it's just too ugly to live.

Do you mean, you prefer the approach that was taken in v1 patch or

I can no longer find v1 of the patch, just v2 and on. Can you send a

[PATCH] blkcg: allocate struct blkcg_gq outside request queue spinlock

[Tahsin Erdogan]

blkg_conf_prep() currently calls blkg_lookup_create() while holding
request queue spinlock. This means allocating memory for struct
blkcg_gq has to be made non-blocking. This causes occasional -ENOMEM
failures in call paths like below:

  pcpu_alloc+0x68f/0x710
  __alloc_percpu_gfp+0xd/0x10
  __percpu_counter_init+0x55/0xc0
  cfq_pd_alloc+0x3b2/0x4e0
  blkg_alloc+0x187/0x230
  blkg_create+0x489/0x670
  blkg_lookup_create+0x9a/0x230
  blkg_conf_prep+0x1fb/0x240
  __cfqg_set_weight_device.isra.105+0x5c/0x180
  cfq_set_weight_on_dfl+0x69/0xc0
  cgroup_file_write+0x39/0x1c0
  kernfs_fop_write+0x13f/0x1d0
  __vfs_write+0x23/0x120
  vfs_write+0xc2/0x1f0
  SyS_write+0x44/0xb0
  entry_SYSCALL_64_fastpath+0x18/0xad

In the code path above, percpu allocator cannot call vmalloc() due to
queue spinlock.

A failure in this call path gives grief to tools which are trying to
configure io weights. We see occasional failures happen shortly after
reboots even when system is not under any memory pressure. Machines
with a lot of cpus are more vulnerable to this condition.

Do struct blkcg_gq allocations outside the queue spinlock to allow
blocking during memory allocations.

v6:
  Due to Jens' objection to conditionally dropping locks based on gfp
  flags, go back to v1 approach.
  Perform queue bypass and policy enabled checks at every iteration.
  Add blkg_lookup_check() to reduce code duplication.

v5:
  Removed stale blkg_alloc() in blkcg_init_queue()

  Pushed down radix_tree_preload() into blkg_create() because it
  disables preemption on return and makes it unsafe to call blocking
  memory allocations.

v4:
  Simplified error checking in blkg_create()
  Factored out __blkg_lookup_create()

v3:
  Pushed down all blkg allocations into blkg_create()

v2:
  Moved blkg creation into blkg_lookup_create() to avoid duplicating
  blkg_lookup_create() logic.

This looks much simpler/cleaner to me, compared to v5. Tejun, what do

So, this patch in itself looks better but now we end up with two
separate mechanisms to handle non-atomic allocations.  This drop lock
/ alloc / relock / check invariants in the main path and preallocation
logic used in the init path.  Right now, both proposed implementations
aren't that satisfactory.  Personally, I'd prefer superficial ugliness
to structural duplications, but, ideally, we shouldn't have to make
this choice.  idk, it's a bug fix.  We can always clean things up
later.

Re: [PATCH] blkcg: allocate struct blkcg_gq outside request queue spinlock

[Julia Lawall]

Is an unlock needed before line 848?  Or does blkg_lookup_check take care
of it?

Unlock is not needed. On success, function returns with locks held.
It is documented at line 805:

"... This function returns with RCU read
 * lock and queue lock held and must be paired with blkg_conf_finish()."
