[PATCH memcg RFC] net: set proper memcg for net_init hooks allocations

[PATCH memcg RFC] net: set proper memcg for net_init hooks allocations

[Vasily Averin]

__register_pernet_operations() executes init hook of registered
pernet_operation structure in all existing net namespaces.

Typically, these hooks are called by a process associated with
the specified net namespace, and all __GFP_ACCOUNTING marked
allocation are accounted for corresponding container/memcg.

However __register_pernet_operations() calls the hooks in the same
context, and as a result all marked allocations are accounted
to one memcg for all processed net namespaces.

This patch adjusts active memcg for each net namespace and helps
to account memory allocated inside ops_init() into the proper memcg.

Dear Vlastimil, Roman,
I'm not sure that memcg is used correctly here, 
is it perhaps some additional locking required?

memcg from obj is unstable, so you need a reference on memcg. You can
introduce get_mem_cgroup_from_kmem() which works for both
MEMCG_DATA_OBJCGS and MEMCG_DATA_KMEM. For uncharged objects (like
init_net) it should return NULL.

Could you please elaborate with more details?
It seems to me mem_cgroup_from_obj() does everything exactly as you say:
- for slab objects it returns memcg taken from according slab->memcg_data
- for ex-slab objects (i.e. page->memcg_data & MEMCG_DATA_OBJCGS)
    page_memcg_check() returns NULL
- for kmem objects (i.e. page->memcg_data & MEMCG_DATA_KMEM) 
    page_memcg_check() returns objcg->memcg
- in another cases
    page_memcg_check() returns page->memcg_data,
    so for uncharged objects like init_net NULL should be returned.

I can introduce exported get_mem_cgroup_from_kmem(), however it should only
call mem_cgroup_from_obj(), perhaps under read_rcu_lock/unlock.

Do you mean something like this?

I think I finally got your point:
Do you mean I should use css_tryget(&memcg->css) for found memcg,
like get_mem_cgroup_from_mm() does?

Thank you,

[PATCH memcg v2] net: set proper memcg for net_init hooks allocations

[Vasily Averin]

__register_pernet_operations() executes init hook of registered
pernet_operation structure in all existing net namespaces.

Typically, these hooks are called by a process associated with
the specified net namespace, and all __GFP_ACCOUNTING marked
allocation are accounted for corresponding container/memcg.

However __register_pernet_operations() calls the hooks in the same
context, and as a result all marked allocations are accounted
to one memcg for all processed net namespaces.

This patch adjusts active memcg for each net namespace and helps
to account memory allocated inside ops_init() into the proper memcg.

Signed-off-by: Vasily Averin <vvs@openvz.org>
---
v2: introduced get/put_net_memcg(),
    new functions are moved under CONFIG_MEMCG_KMEM
    to fix compilation issues reported by Intel's kernel test robot

v1: introduced get_mem_cgroup_from_kmem(), which takes the refcount
    for the found memcg, suggested by Shakeel

[PATCH memcg v3] net: set proper memcg for net_init hooks allocations

[Vasily Averin]

__register_pernet_operations() executes init hook of registered
pernet_operation structure in all existing net namespaces.

Typically, these hooks are called by a process associated with
the specified net namespace, and all __GFP_ACCOUNTING marked
allocation are accounted for corresponding container/memcg.

However __register_pernet_operations() calls the hooks in the same
context, and as a result all marked allocations are accounted
to one memcg for all processed net namespaces.

This patch adjusts active memcg for each net namespace and helps
to account memory allocated inside ops_init() into the proper memcg.

v3: put_net_memcg() replaced by an alreay existing mem_cgroup_put()

Please, rename it to get_mem_cgroup_from_obj() for consistency.

I'm not a fan of this helper: it has nothing to do with the networking,
actually it's a wrapper of get_mem_cgroup_from_kmem() replacing NULL
with root_mem_cgroup.

Overall the handling of root_mem_cgroup is very messy, I don't blame
this patch. But I wonder if it's better to simple move this code
to the call site without introducing a new function?

Alternatively, you can introduce something like:
struct mem_cgroup *mem_cgroup_or_root(struct mem_cgroup *memcg)
{
	return memcg ? memcg : root_mem_cgroup;
}

Unfortunately root_mem_cgroup is defined under CONFIG_MEMCG,
so we cannot use it outside without ifdefs.

Do we need memcg_kmem_enabled() check here or maybe
mem_cgroup_from_obj() should be doing memcg_kmem_enabled() instead of

I reckon such a guard is on the charge side and readers should treat
NULL and root_mem_group equally. Or is there a case when these two are
different? 

(I can see it's different semantics when stored in current->active_memcg
(and active_memcg() getter) but for such "outer" callers like here it
seems equal.)

Michal

I was more thinking about possible shortcut optimization and unrelated
to this patch.

Vasily, can you please add documentation for get_mem_cgroup_from_obj()
similar to get_mem_cgroup_from_mm()? Also for mem_cgroup_or_root().
Please note that root_mem_cgroup can be NULL during early boot.

Shakeel, unfortunately I'm not ready to answer this question right now.
I even did not noticed that memcg_kmem_enabled() and mem_cgroup_disabled()
have a different nature.
If you have no objections I'm going to keep this place as is and investigate
this question later.

Dear Michal,
I may have misunderstood your point of view, so let me explain my vision
in more detail.
I do not think that NULL and root_mem_cgroup are equal here:
- we have enabled cgroups and well-defined root_mem_cgroup,
- this function is called from inside memcg-limited container,
- we tried to get memcg from net, but without success,
  and as result got NULL from  mem_cgroup_from_obj()
  (frankly speaking I do not think this situation is really possible)
If we keep memcg = NULL, then current's memcg will not be masked and
net_init's allocations will be accounted to current's memcg. 
So we need to set active_memcg to root_mem_cgroup, it helps to avoid
incorrect accounting.

Ok, thank you for the remark, I'll improve it in next patch version.

It's way out of scope of this patch, but I think we need to stop
using NULL as root_mem_cgroup/system scope indicator. Remaining use cases
will be like end of cgroup iteration, active memcg not set, parent of the
root memcg, etc.
We can point root_mem_cgroup at a statically allocated structure
on both CONFIG_MEMCG and !CONFIG_MEMCG.
Does it sound reasonable or I'm missing some important points?

Thanks!

I expect Embedded developers will be highly disagree.
Pointer only should be acceptable for them.

Patch is good as is. Just add the documentation to the functions in

I noticed that the kernel already has a function get_mem_cgroup_from_objcg(),
the name of which is very similar to my new function get_mem_cgroup_from_obj().
Maybe it's better to rename my function to get_mem_cgroup_from_ptr()?

I don’t think it’s a problem: objcg is a widely used abbreviation and in my opinion is different enough from obj. I’d keep it for the consistency with the mem_cgroup_from_obj().

Thanks!

[PATCH memcg v5] net: set proper memcg for net_init hooks allocations

[Vasily Averin]

__register_pernet_operations() executes init hook of registered
pernet_operation structure in all existing net namespaces.

Typically, these hooks are called by a process associated with
the specified net namespace, and all __GFP_ACCOUNT marked
allocation are accounted for corresponding container/memcg.

However __register_pernet_operations() calls the hooks in the same
context, and as a result all marked allocations are accounted
to one memcg for all processed net namespaces.

This patch adjusts active memcg for each net namespace and helps
to account memory allocated inside ops_init() into the proper memcg.

v5: documented get_mem_cgroup_from_obj() and for mem_cgroup_or_root()
    functions, asked by Shakeel.

v4: get_mem_cgroup_from_kmem() renamed to get_mem_cgroup_from_obj(),
    get_net_memcg() renamed to mem_cgroup_or_root(), suggested by Roman.

v3: put_net_memcg() replaced by an alreay existing mem_cgroup_put()
    It checks memcg before accessing it, this is required for
    __register_pernet_operations() called before memcg initialization.
    Additionally fixed leading whitespaces in non-memcg_kmem version
    of mem_cgroup_from_obj().

v2: introduced get/put_net_memcg(),
    new functions are moved under CONFIG_MEMCG_KMEM
    to fix compilation issues reported by Intel's kernel test robot

v1: introduced get_mem_cgroup_from_kmem(), which takes the refcount
    for the found memcg, suggested by Shakeel

[PATCH memcg v6] net: set proper memcg for net_init hooks allocations

[Vasily Averin]

__register_pernet_operations() executes init hook of registered
pernet_operation structure in all existing net namespaces.

Typically, these hooks are called by a process associated with
the specified net namespace, and all __GFP_ACCOUNT marked
allocation are accounted for corresponding container/memcg.

However __register_pernet_operations() calls the hooks in the same
context, and as a result all marked allocations are accounted
to one memcg for all processed net namespaces.

This patch adjusts active memcg for each net namespace and helps
to account memory allocated inside ops_init() into the proper memcg.

v6: re-based to current upstream (v5.18-11267-gb00ed48bb0a7)

v5: documented get_mem_cgroup_from_obj() and for mem_cgroup_or_root()
    functions, asked by Shakeel.

v4: get_mem_cgroup_from_kmem() renamed to get_mem_cgroup_from_obj(),
    get_net_memcg() renamed to mem_cgroup_or_root(), suggested by Roman.

v3: put_net_memcg() replaced by an alreay existing mem_cgroup_put()
    It checks memcg before accessing it, this is required for
    __register_pernet_operations() called before memcg initialization.
    Additionally fixed leading whitespaces in non-memcg_kmem version
    of mem_cgroup_from_obj().

v2: introduced get/put_net_memcg(),
    new functions are moved under CONFIG_MEMCG_KMEM
    to fix compilation issues reported by Intel's kernel test robot

v1: introduced get_mem_cgroup_from_kmem(), which takes the refcount
    for the found memcg, suggested by Shakeel

Roman, Shakeel, I need your help

Should we perhaps verify kaddr via virt_addr_valid() before using virt_to_page()
If so, where it should be checked?

So, the two call stacks tell the addresses belong to the kernel
modules (nfnetlink and nf_tables) whose underlying memory is allocated
through vmalloc and virt_to_page() does not work on vmalloc()
addresses.

I think virt_addr_valid() check in mem_cgroup_from_obj() should work
but I think it is expensive on the arm64 platform. The cheaper and a
bit hacky way to avoid such addresses is to directly use
is_vmalloc_addr() directly.

However in both these cases get_mem_cgroup_from_obj() -> mem_cgroup_from_obj() ->
virt_to_folio() -> virt_to_page() -> virt_to_pfn() -> __virt_to_phys() 
handles address of struct net taken from for_each_net().
The only net namespace that exists at this stage is init_net,
and dmesg output confirms this:
"virt_to_phys used for non-linear address: ffffd8efe2d2fe00 (init_net)"

I do not understand why you mean that processed address is vmalloc-specific.
As far as I understand it is valid address of static variable, and for some reason
arm64 does not consider them valid virtual addresses.

Indeed you are right as we are using the addresses of net namespaces
and the report already has the information on the address
ffffd8efe2d2fe00 which is init_net.

I don't know what is the right way to handle such addresses on arm64.
BTW there is a separate report on this issue and arm maintainers are
also CCed. Why not ask this question on that report?

Hello!

I'm unable to boot my sparc64 VM anymore (5.19 still boots, 6.0-rc1 does not),
bisected up to this patch,

mator@ttip:~/linux-2.6$ git bisect bad
1d0403d20f6c281cb3d14c5f1db5317caeec48e9 is the first bad commit
commit 1d0403d20f6c281cb3d14c5f1db5317caeec48e9
Author: Vasily Averin <vvs@openvz.org>

    net: set proper memcg for net_init hooks allocations

    __register_pernet_operations() executes init hook of registered
    pernet_operation structure in all existing net namespaces.

    Typically, these hooks are called by a process associated with the
    specified net namespace, and all __GFP_ACCOUNT marked allocation are
    accounted for corresponding container/memcg.

    However __register_pernet_operations() calls the hooks in the same
    context, and as a result all marked allocations are accounted to one memcg
    for all processed net namespaces.

    This patch adjusts active memcg for each net namespace and helps to
    account memory allocated inside ops_init() into the proper memcg.

Hello.

Thanks for the report.

The failed address falls into vmmemmap region (per your boot log
output). It looks like the respective page/folio (of init_net struct) is
unbacked there (and likely folio_test_slab fails dereferencing ->flags). 

Would you mind sharing your kernel's config?
(I'm most curious about CONFIG_SPARSMEM_VMEMMAP, I'm not familiar with
your arch at all though.)

Thanks,
Michal

Forgive my uniformed chime-in but Linus seemed happy with the size of
-rc7 and now I'm worried there won't be an -rc8. AFAICT this is a 6.0
regression. Vasily, Shakeel, do we have a plan to fix this?

I was actually waiting for Vasily to respond. Anyways, I think the
easiest way to proceed is to revert the commit 1d0403d20f6c ("net: set
proper memcg for net_init hooks allocations"). We can debug the issue
in the next cycle.

If agreeable, could someone please send along a tested and changelogged
patch to do this?

I will send this revert soon and I think Anatoly has already tested
the revert but I will let him add his tested-by tag.

Thx for getting this regression tracked using regzbot. FWIW, that went
sideways (as your already noticed and mentioned on IRC), as that made
regzbot treat *your* mail as the report of the regressions. In cases
like this you need "#regzbot ^introduced 1d0403d20f6c" (since recently
"#regzbot introduced 1d0403d20f6c ^" works, too), as then regzbot will
consider the *parent* mail the report (and then regzbot will look out
for patches that link to them using a Link: tag).

No worries, I did the same mistake a few time already :-D I send a mail
with that command now, so let's resolve this subthread by marking it invalid

#regzbot invalid: mis-used regzbot command, now properly tracked

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.

[Thorsten Leemhuis]

TWIMC: this mail is primarily send for documentation purposes and for
regzbot, my Linux kernel regression tracking bot. These mails usually
contain '#forregzbot' in the subject, to make them easy to spot and filter.

[TLDR: I'm adding this regression report to the list of tracked
regressions; all text from me you find below is based on a few templates
paragraphs you might have encountered already already in similar form.]

Hi, this is your Linux kernel regression tracker.

Thanks for the report. To be sure below issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression
tracking bot:

#regzbot ^introduced 1d0403d20f6c281cb3d14c5f1db5317caeec48e9
#regzbot title cgroups/sparc64: sparc64 fails to boot
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply -- ideally with also
telling regzbot about it, as explained here:
https://linux-regtracking.leemhuis.info/tracked-regression/

Reminder for developers: When fixing the issue, add 'Link:' tags
pointing to the report (the mail this one replies to), as explained for
in the Linux kernel's documentation; above webpage explains why this is
important for tracked regressions.
