kmemleak for MIPS

kmemleak for MIPS

[naveen yadav]

Hi all,

I want to check kmemleak for both ARM/MIPS. i am able to find kernel
patch for ARM at
http://linux.derkeiler.com/Mailing-Lists/Kernel/2009-04/msg11830.html.
But I could not able to trace patch for MIPS.

Kind Regards
Naveen

It seems that kmemleak is not supported on MIPS.

According to 'depends on' config entry it is supported on:
x86, arm, ppc, s390, sparc64, superh, microblaze and tile.

Cătălin, can you confirm this? I will send a patch to update
Documentation/kmemleak.txt.

Also, looking forward to work on making kmemleak available on MIPS.

thanks,
Daniel.

It's not supported probably because no-one tried it, kmemleak is pretty
architecture-independent. You may need to add some standard symbols to
the vmlinux.lds.S if the linker complains and possibly annotate some
false positives if you get any.

Just add "depends on MIPS" and give it a try.

symbol  _sdata ), I was able to add kmemleak support for MIPS.

You may want to disable the kmemleak testing to reduce the amount of
leaks reported.

You may want to disable the kmemleak testing to reduce the amount of
leaks reported.

These are probably false positives. Since the pointer referring this
block (udp_table) is __read_mostly, is it possible that the
corresponding section gets placed outside the _sdata.._edata range?

Re: kmemleak for MIPS

[Maxin John]

Hi,

The kmemleak results in MIPS that I have included in the previous mail
were obtained during the booting of the malta kernel.
Later, I have checked the "real" usage by using the default
"kmemleak_test" module.

Following output shows the kmemleak results when I used the "kmemleak_test.ko"

The previous results could be false positives. However, the current
results are not false positives as we have intentionally created the
memory leaks using the test module.

Yes, that's fine to test kmemleak and show that it reports issues on
MIPS. But it shouldn't report other leaks if the test module isn't
loaded at all (removing it wouldn't remove the leaks reported as they
are permanent).

I was only referring to those leaks coming from udp.c and ignored the
kmemleak tests (that's why I said that you should run it again without
the kmemleak_test.ko).

Boot the kernel with kmemleak enabled but don't load kmemleak_test.ko.
Than you can either wait 10-15 minutes or force a scan with:

echo scan > /sys/kernel/debug/kmemleak
echo scan > /sys/kernel/debug/kmemleak
cat /sys/kernel/debug/kmemleak.

Thank a lot for this information.  Based on this, I will check it
again in the MIPS platform.

The standard kmemleak test case is behaving as expected. Based on
this, I think, we can say that the kmemleak support for MIPS is
working.

If you for the kmemleak scan (via echo) a few times, do you get more
leaks? The udp_table_init() function looks like it could leak some
memory but I haven't seen it before. I'm not sure whether this is a
false positive or a real leak.

Looking again at udp_init_table it seem that a memory leak is possible.
Could you post your .config and the full output of dmesg after booting.

A situation where CONFIG_BASE_SMALL is 0, and
table->mask < UDP_HTABLE_SIZE_MIN - 1 would lead
to a memory leak.

Furthermore, you can add some printks inside udp_init_table
and check what is really happening there. ([1])

Daniel.

It's worth printing the table->mask on MIPS as well. I think have the
same configuration on ARM and put some printk's but the table->mask is
set to higher value and the second if condition is false. The checks
could be simply reordered but I don't know the reasoning behind the
current code sequence (I cc'ed Eric).

Thanks. I will check it.

Re: kmemleak for MIPS

[Daniel Baluta]

We have:

> UDP hash table entries: 128 (order: 0, 4096 bytes)
> CONFIG_BASE_SMALL=0

udp_table_init looks like:

        if (!CONFIG_BASE_SMALL)
                table->hash = alloc_large_system_hash(name, .. &table->mask);
        /*
         * Make sure hash table has the minimum size
         */

Since CONFIG_BASE_SMALL is 0, we are allocating the hash using
alloc_large_system
Then:
        if (CONFIG_BASE_SMALL || table->mask < UDP_HTABLE_SIZE_MIN - 1) {
                table->hash = kmalloc();

table->mask is 127, and UDP_HTABLE_SIZE_MIN is 256, so we are allocating again
table->hash without freeing already allocated memory.

We could free table->hash, before allocating the memory with kmalloc.
I don't fully understand the condition table->mask < UDP_HTABLE_SIZE_MIN - 1.

Eric?

thanks,
Daniel.

Indeed (on my ARM system the reported UDP hash table entries is 512, so
I don't get the memory leak).

We don't have the equivalent of free_large_system_hash(). Reordering the
'if' blocks may be better.

How much memory do you have exactly on this machine ?

alloc_large_system_hash() has no parameter to specify a minimum hash
table, and UDP needs one.

If you care about losing 8192 bytes of memory, you could boot with

"uhash_entries=256"

I can live with this, but is bad practice to have leaks even small ones.
Our concern was, to see if kmemleak with Maxin's patch
generates false positives.

So, I guess everything is fine regarding udp_init_table. We can move on,
integrating MIPS support for kmemleak :).

Hi,

I have compiled the kernel with below given modification in .config

CONFIG_CMDLINE="uhash_entries=256"

After booting with the new kernel, the "kmemleak" no longer complains
about the "udp_table_init".
However it do report another possible leak :)

Hmm, then MIPS kmemleak port might have a problem with percpu data ?

fcp->hash_table = kzalloc_node(sz, GFP_KERNEL, cpu_to_node(cpu));

fcp is a per cpu "struct flow_cache_percpu"

Thank you very much for the inputs. I will definitely investigate this.
However, I think, the "basic" kmemleak support for MIPS is working as
expected with the present patch.
The kmemleak test case is also working as expected in MIPS target.

So, as Daniel mentioned, shall we go ahead with integrating the
kmemleak support for MIPS ?

Please let me know your comments.

I can't figure out what it is. Kmemleak uses this block for scanning the
percpu data:

	for_each_possible_cpu(i)
		scan_block(__per_cpu_start + per_cpu_offset(i),
			   __per_cpu_end + per_cpu_offset(i), NULL, 1);

The __per_cpu_* symbols seem to be correctly defined in the MIPS
vmlinux.lds.S as it uses the PERCPU macro directly.

Other chunks allocated via pcpu_mem_alloc() should be tracked by
kmemleak and either reported as leaks or scanned (and not reporting
subsequent blocks referred from the percpu memory).

There is nothing special. UDP algo needs a minimum hash table that
alloc_large_system_hash() was not able to provide (???)

As you spotted, there is no free_large-system_hash(), so we 'leak' the
small hash table.

If machine has not enough memory to provide such a small hash table, I
suggest using CONFIG_BASE_SMALL, since :

#define UDP_HTABLE_SIZE_MIN (CONFIG_BASE_SMALL ? 128 : 256)

As Daniel suggested, this could be a real leak . However, we need to
confirm this.

 udp_table_init() -> alloc_large_system_hash() ->  alloc_pages_exact()

Kmemleak for mips

[Luis R. Rodriguez]

Curious what the limitations are on restricting kmemleak to non-mips
archs. I have a user and situation [1] where this could be helpful [1]
in debugging an issue. The user reports he cannot enable it on mips.

It may just work but cannot be enabled because I cannot test kmemleak on
such hardware. In general you need to make sure that the _sdata/_edata
and __bss_start/__bss_stop symbols are defined. If there are other ways
of allocating memory than the standard API, it would need additional
hooks. Some false-positives specific to MIPS may need to be annotated
(usually with kmemleak_not_leak).

(btw, you could also merge the kmemleak.git tree on git.kernel.org as it
has improvements on the rate of false positives; the patches will be
pushed in 2.6.33-rc1)
