CFQ and dm-crypt

CFQ and dm-crypt

[Richard Kralovic]

[-- Attachment #1: Type: text/plain, Size: 766 bytes --]

CFQ io scheduler relies on using task_struct current to determine which
process makes the io request. On the other hand, some dm modules (such
as dm-crypt) use separate threads for doing io. As CFQ sees only these
threads, it provides a very poor performance in such a case.

IMHO the correct solution for this would be to store, for every io
request, the process that initiated it (and preserve this information
while the request is processed by device mapper). Would that be feasible?

Other possibility is to avoid using separate threads for doing io in dm
modules. The attached patch (against 2.6.36) modifies dm-crypt in this
way, what results into much better behavior of cfq (e.g., io priorities
work correctly).

Yes, this seems to be correct solution. I think this should be
handled by core device-mapper (as you noted, more dm targets using
threads to process.)

Sorry, this completely dismantles the way how dm-crypt solves problems
with stacking dm devices.
Basically it reintroduces possible deadlocks for low memory
situations (the reason why there are these threads).

Do you think it is possible to handle this in device-mapper, without any
support from the cfq code?

I also noticed that a solution for this problem was proposed a few years
ago by Hirokazu Takahashi (a patch for linux-2.6.25,
http://lkml.org/lkml/2008/4/22/193), but there was no response to it. Is
such an approach wrong?

Would the problem with deadlock be still present if the io worker queue
was used for writes only, but reads were issued directly? (Even this
would be a significant improvement for people using cfq and a full-disk
encryption over dm-crypt, since asynchronous writes are not supported by
cfq anyway.)

Not sure but it will be discussed now.
There are more situations where the process id is lost because of other queue,
a lot of new recent code (including internal thread in dm-core).

Sorry, both must be issued from separate thread, you must not block in
common crypt_map() call:

- READ must first allocate BIO clone for ciphertext data
(it can wait here - memory allocation, imagine it waits for swap -> swap is
on another crypt device -> deadlock)

- WRITES first run encryption thus must allocate memory too.
Moreover if encryption runs in async mode, it can block when encryption queue
is full (waiting for condition triggerred from async callback) -> again,
possible deadlock if in common thread.

Of course it will work most of the time, but the design must be robust even
for not common situations.

It would probably be helpful to CC Jens (which I did).

I haven't looked very deeply at the approach in the referenced mail
thread (though I did look far enough to tell that the aio bits were
wrong), but in general I think this sort of thing is worthwhile.  I'm
not sure what the barriers are.  Jens?

Richard,

So what problem are you facing? I know you are referring to CFQ ioprio not
working with dm targets but how does it impact you? So it is not about
overall disk performance or any slow down with dm-crypt target but just
about prioritizing your IO over other?

Conceptually it makes sense to put some kind of info in bio so that we
can associate with right context. I think above thread kind of of died
down.

Re-reading the thread now, and it looks like that Hirokazu also planned
to use this info for associating IO to right cgroup for WRITES. There
was alternative approach of "IO tracking" where IO controller cgroup
info was to be put in page_cgroup structure and once the bio is submitted
to CFQ, it will trace the page/page_cgroup for bio and extract the 
cgroup info and attribute IO to right group.

Storing some info in page_cgroup makes it dependent on memory controller
and which should not be a necessary thing for READS. For WRITES it probably
is still a necessary thing as it also provides (work in progress from greg)
per cgroup dirty ratio.

Storing some kind of io context info in bio makes sense to me. Not sure
if Jens has other ideas.

Thanks
Vivek

The ioprio not working is probably the biggest problem (since it is used
quite a lot for background tasks like desktop indexing services). But
also the overall performance is worse. I didn't do a rigorous
benchmarking, but tried a following simple test to see the impact of my
dm-crypt patch:

test-write:

SIZE=640


KERN=`uname -r`
((time /bin/bash -c "dd if=/dev/zero bs=1M count=64 \
   of=normal.tst oflag=direct") 1>$KERN-write-normal 2>&1) |
((time /bin/bash -c "ionice -c 3 dd if=/dev/zero bs=1M \
   count=64 of=idle.tst oflag=direct") 1>$KERN-write-idle 2>&1)

Times for vanilla kernel (with CFQ) were 5.24s for idle and 5.38s for
normal, times for patched kernel were 4.9s for idle and 3.13s for
normal. A similar test for reading showed even bigger differences:
vanilla kernel has 8.5s for idle as well as 8.5s for normal, patched
kernel has 4.2s for idle and 2.1s for normal.

So it seems that CFQ is behaving really badly if it is not able to see
which process is doing the IO (and sees kcryptd everywhere). As far as I
understood, there is no point in using CFQ in that case and it is much
better to use other scheduler in this situation.

Ok, so are you getting better results with noop and deadline?

So your bigger concerns seems to be not necessarily making ioprio and
class working but why there is a performance drop when dm-crypt starts
submitting IOs with the help of a worker thread and we lose original
context.

If you are getting better numbers say with noop, then I would think that
somehow we are idling a lot in CFQ (with dm-crypt) and it is overshadowing
the benefits of reduced seeks due to idling (if any). 

Is it possible to capture a trace with CFQ using blktrace. Say 30 second
trace for two cases. Vanilla CFQ and patched CFQ with normal case (Will
look into the case of IDLE later). I want to compare two traces and see
what changed in terms of idling.

One explanation could that your workload is sequential (dd case), and
by exposing the context to CFQ you are getting the idling right and
reducing some seeks. By submitting everything from kcryptd, I think it
practically becomes a seeky traffic (read/write intermixed) and increased
seeks reduce throughput. But if this is the case, same should be true
for noop and i do not understand why you would get better performance
with noop.

Anyway, looking at blktrace might give some idea.

Thanks
Vivek

Sure.  Try the attached patch (still an rfc) and let us know how it
goes.  In my environment, it speed up multiple concurrent buffered
readers.  I wasn't able to do a full analysis via blktrace as 2.6.37-rc1
seems to have broken blktrace support on my system.

Thanks for the patch. Unfortunately, I got a kernel panic quite soon
after booting the patched kernel. I was not able to reproduce the
panic in a virtual machine, so I had to manually note the backtrace,
thus I apologize that it's incomplete:

Fatal exception in interupt.
...
do_invalid_op
cic_free_func 0x9d/0xb0
bio_endio 0x42/0x70
task_rq_lock
try_to_wake_up
invalid_op
cic_free_func
cfq_free_io_context
put_io_context
cfq_put_request
...

When I combined the patch with my previous hack on dm-crypt, it worked
fine; so the problem apparently goes away if cfq sees the corret io
context.

Moreover, I noticed in the sources that cfq still uses current task on
many places. For example, the CPU scheduler settings are inherited if
there is no io priority set. Hence I was wondering if it does not make
more sense to store whole task_struct of the initiating process in
bio, instead of just io_context?

Hmm, clearly a reference counting issue.  I can't reproduce it, but I'll
keep staring and trying.

OK, good to know, thanks for the info.

It's actually not that many.  elv_may_queue should also get passed the
io_context (and I've since fixed that in my local version).  The cgroup
code may actually require the task;  I'm waiting to hear back from Vivek
to see if there's a way to get from io_context to cgroup.  As for the io
priority, it may be that we can set that in the io_context as well.  I'm
not completely sure I agree with linking a task struct into a bio.  It
may make the exit path a bit tricky.  I'll think more about it if it
comes to that.

Thanks for the testing and the thoughtful comments.  I'll let you know
when I have another patch for testing (though I'm at the Linux Plumbers
Conference, so I'm not sure how much time I'll have to dedicate to the
task this week).

Cheers,
Jeff

Hi, Richard,

I have another patch for you to try.  This one holds up pretty well in
my testing using a dm-crypt target.  Without the patch, I see no
priority separation:

total data transferred: 882080
class	prio	ideal	xferred	%diff
be	0	180425	110068	-39
be	1	160378	110580	-32
be	2	140330	110068	-22
be	3	120283	110580	-9
be	4	100236	110068	9
be	5	80189	110580	37
be	6	60141	110068	83
be	7	40094	110068	174

After the patch, there is definitely differentiated service:

total data transferred: 899716
class	prio	ideal	xferred	%diff
be	0	184032	388084	110
be	1	163584	191476	17
be	2	143136	125428	-13
be	3	122688	70644	-43
be	4	102240	53976	-48
be	5	81792	36212	-56
be	6	61344	20852	-67
be	7	40896	13044	-69

I've yet to make changes to the cfq_get_cfqg function to take advantage
of the io_context passing, but it should be simple enough, and can be
added as a follow-on patch.

So, give it a try and let me know how you fare.

Cheers,
Jeff

Hello,

I am sorry for a late reply (it took me some time to try the patch on
my main machine). Thank you for your work; unfortunately, I'm still
getting a panic at early boot stages: The BUG_ON assert in
cfq-iosched.c:cic_free_func failed, with a call trace as follows:

<IRQ>
cfq_free_io_context
put_io_context
cfq_put_request
elv_put_request
blk_finish_request
...

I applied your patch at Linus's git tree (commit
b86db4744230c94e480de56f1b7f31117edbf193), it applied cleanly.

I tried a little to find the source of the problem, but without
success so far. However, I think that calling put_io_context in
bio_endio only may introduce memory leaks under certain situations
(although this is probably not related to the panic I get):

In blk-core.c:blk_rq_prep_clone, __bio_clone allocates the io_context,
but if subsequent allocations fail, bio_free in free_and_out does not
free it.

Similarly, in dm-crypt.c:crypt_alloc_buffer, bio_put does not
free the io_context.

Or have I misunderstood something?

Odd... Can you give me more information on your hardware and
device-mapper setup so I can try to reproduce it?

Sure, I am attaching my .config. I am using a full disk encryption,
raw partitions are like this:

Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          31      248976   83  Linux
/dev/sda2              32       19457   156039345   83  Linux

/dev/sda2 is physical volume for encryption via dm-crypt. There are 2
encrypted lvm partitions - root and swap. /dev/sda1 is boot partition.
(This is the setup created by debian installer.)

Let me know if I can be of any other help.
