Already the patch to make kmemcheck and kmemleak mutually exclusive is
underway. It is not surprising that kmemleak is scanning uninitialized
memory. But if you say that you have tried it before, it is strange
that it didn't appear until now.
In any case, I don't think it is very productive to run them both at
the same time, simply because kmemcheck slows every memory access down
so much and scanning memory doesn't exactly help that. It _could_ be
useful to have them compiled into the same kernel, though, e.g. a
distro "-debug" kernel.
Maybe you can just add the "depends on !KMEMLEAK" to CONFIG_KMEMCHECK
in tip/out-of-tree for now?

Why isn't it surprising? Yes, it's non-fatal for kmemleak to scan
uninitialized memory but we could be looking at non-initialized struct
member that's a bug waiting to happen elsewhere in the code (that
doesn't trigger often).

It isn't surprising to me either. Kmemleak scans the memory periodically
but it cannot know whether such memory was initialised or not to avoid
scanning it. So I would expect such warnings if both kmemleak and
kmemcheck are enabled. Scanning uninitialised memory is fine with
kmemleak, it just increases the number of false negatives (with
SLAB_DEBUG enabled, however, the allocated blocks are pre-initialised).
So kmemleak and kmemcheck should be exclusive, unless there is a way for
kmemleak to validate an address with kmemcheck before deciding whether
to scan a memory block.

It's possible. Look at the kmemcheck_shadow_lookup() and
kmemcheck_shadow_test() calls in kmemcheck_read_strict(), for example.
Vegard, what do you think? I think making kmemcheck and kmemleak play
nice with each other is useful for people like Ingo who do automated
testing.

i think it would be far more intelligent to annotate those accesses
by kmemleak as 'trust me, dont check'. Willing to test such a patch.

There's already a couple of exclusion rules in kmemcheck:
menuconfig KMEMCHECK
bool "kmemcheck: trap use of uninitialized memory"
depends on DEBUG_KERNEL
depends on !X86_USE_3DNOW
depends on SLUB || SLAB
depends on !CC_OPTIMIZE_FOR_SIZE
depends on !FUNCTION_TRACER
such type of Kconfig driven exclusion is usually a somewhat lame way
to express limitations in the software.
CC_OPTIMIZE_FOR_SIZE is an externality that cannot be eliminated,
but the others could be improved - and we should definitely not
extend the list of exclusions.

I guess something like this totally untested patch should do it. Vegard,

Looks good - but doesnt apply cleanly to -tip because i picked up a
number of kmemleak patches into tip:out-of-tree for testing - so
i'll leave it up for Vegard/Catalin to do a blessed version of it
against the kmemleak tree - which i hope will apply fine to tip too

I don't know so much about the kmemleak internals, but this I can say
about the kmemcheck part: According to your definition, an object is
initialized if all the bytes of an object are initialized.
Is it possible that because of this, if we have a partially
uninitialized object, kmemleak will not record the pointers found in
that object? If so, it might skip valid pointers, and deem an object
unreferenced. Which could make kmemleak give false-positives.
I think it would be better to ask kmemcheck on a per-pointer basis
(i.e. for each pointer-sized word in the object), whether it is
initialized or not.

Yes, that's possible.
Does kmemcheck work on a page-range basis. If an object doesn't cross
page boundaries, would it be considered fully initialised after writing
a single location?

This should work but how expensive is this check?

Everything in kmemcheck is expensive :-). kmemcheck_shadow_lookup()
needs to do PTE lookup to find the shadow page where we record object
states. I'm not sure why that's a problem, though. If you've enabled
kmemcheck, everything is already dead slow and kmemleak scanning happens
in background, no? Furthermore, I think we need to do it the way Vegard
suggested to avoid false positives.

I think this patch should work. With a few minor (aesthetic) things

There is a BYTES_PER_POINTER macro defined in the kmemleak.c file, you
could use that instead of sizeof(unsigned long).
Thanks.

Nice. In fact this improves kmemleak efficiency as it reduces the
amount of false negatives: we wont interpret a random old pointer in
already-freed memory as a true 'reference'.
kmemcheck+kmemleak combo bootups might be Da Bomb of the future, in
terms of testing ;-)

It happens in background but the scan_block() function is called, in
most cases, with interrupts disabled and a spinlock held (to avoid the
object being freed during scanning). In my kmemleak branch, queued for
the next merging window, there are patches to allow rescheduling during
object scanning (by releasing the lock temporarily), so it shouldn't be
a problem.

The problem here is that kmemleak will scan partially initialized
objects that makes kmemcheck complain. Fix that up by skipping
uninitialized memory regions when kmemcheck is enabled.

Vegard? Ingo? The patch is based on tip/out-of-tree so it probably
should go to the kmemleak tree?

With the relevant ack, I can merge it in the kmemleak tree and push it
to Linus when the window opens.

I'm testing it currently - but yeah, i'd agree that it should go
into the kmemleak tree, with a .32 merge date or so.

btw., i re-tested the original tree, and got the lockup/crash below.

Do you have the "Allow rescheduling during object scanning" patch? Apart
from that, you may need another for not holding the tasklist_lock when
scanning the task stacks - it is at the top of my kmemleak branch,
together with a patch or informing kmemleak about thread stack
allocations
(http://www.linux-arm.org/git?p=linux-2.6.git;a=shortlog;h=refs/heads/kmemleak).
With these patches, I don't get any soft lockups on my system.

Ingo/Vegard, ACK/NAK? I don't want my amazingly good patch to end up
in /dev/null so can we just shove it in kmemleak.git?
