[RFC PATCH bpf-next 00/10] bpf, mm: Add a new item bpf into memory.stat for the observability of bpf memory

[Yafang Shao]

This patchset adds a new item 'bpf' into memory.stat to show the bpf
memory usage in each memcg (except the root memcg because kmem is not
charged into root memcg now). The bpf memory usage is not trivial, so it
deserves a new item.

Patches #1 ~ #8 are from another series[1] which try to fix the pinned bpf
issues, but it seems to be a long way to go. So let's do the observability
first, which has been in my local repo for a long time.

We use the scope-based accouting/unaccouthing to track the bpf memory
usage, which is similar with the way how we charge bpf memory.

We have to annotate both allocations and releases of bpf memory because we
don't want to add something into struct page currently. The allocations
and releases of bpf memory are very clear, so it won't be a trouble.

This patchset only tracks the memory of bpf-map currently.

Future works:
- track the memory of bpf-prog
- observe system-wide bpf memory usage by adding this item into root memcg
- per-map and per-prog bpf memory usage in bpftool or something else
- give user an option to disable memcg-based bpf accouting [2]

Any feedback is welcomed.

[Yafang Shao]

We can use this helper when CONFIG_MEMCG_KMEM or CONFIG_MEMCG is not set.
It also moves bpf_map_{get,put}_memcg into include/linux/bpf.h, so
these two helpers can be used in other source files.

[RFC PATCH bpf-next 03/10] bpf: Call bpf_map_init_from_attr() immediately after map creation

[Yafang Shao]

In order to make all other map related memory allocations been allocated
after memcg is saved in the map, we should save the memcg immediately
after map creation. But the map is created in bpf_map_area_alloc(),
within which we can't get the related bpf_map (except with a pointer
casting which may be error prone), so we can do it in
bpf_map_init_from_attr(), which is used by all bpf maps.

bpf_map_init_from_attr() is executed immediately after
bpf_map_area_alloc() for almost all bpf maps except bpf_struct_ops,
devmap and hashmap, so this patch changes these three maps.

In the future we will change the return type of bpf_map_init_from_attr()
from void to int for error cases, so put it immediately after
bpf_map_area_alloc() will make it eary to handle the error case.

[RFC PATCH bpf-next 04/10] bpf: Save memcg in bpf_map_init_from_attr()

[Yafang Shao]

Move bpf_map_save_memcg() into bpf_map_init_from_attr(), then all other
map related memory allocation will be allocated after saving the memcg.
And then we can get memcg from the map in the followup memory allocation.

To pair with this change, bpf_map_release_memcg() is moved into
bpf_map_area_free(). A new parameter struct bpf_map is introduced into
bpf_map_area_free() for this purpose.

[RFC PATCH bpf-next 05/10] bpf: Use scoped-based charge in bpf_map_area_alloc

[Yafang Shao]

Currently bpf_map_area_alloc() is used to allocate a container of struct
bpf_map or members in this container.  To distinguish the map creation
and the other case, a new parameter struct bpf_map is added into
bpf_map_area_alloc(). Then for the non-map-creation case, we could get
the memcg from the map instead of using the current memcg.

[RFC PATCH bpf-next 10/10] bpf, memcg: Add new item bpf into memory.stat

[Yafang Shao]

A new item 'bpf' is introduced into memory.stat, then we can get the memory
consumed by bpf. Currently only the memory of bpf-map is accounted.
The accouting of this new item is implemented with scope-based accouting,
which is similar to set_active_memcg(). In this scope, the memory allocated
will be accounted or unaccounted to a specific item, which is specified by
set_active_memcg_item().

The result in cgroup v1 as follows,
	$ cat /sys/fs/cgroup/memory/foo/memory.stat | grep bpf
	bpf 109056000
	total_bpf 109056000
After the map is removed, the counter will become zero again.
        $ cat /sys/fs/cgroup/memory/foo/memory.stat | grep bpf
        bpf 0
        total_bpf 0

The 'bpf' may not be 0 after the bpf-map is destroyed, because there may be
cached objects.

Note that there's no kmemcg in root memory cgroup, so the item 'bpf' will
be always 0 in root memory cgroup. If a bpf-map is charged into root memcg
directly, its memory size will not be accounted, so the 'total_bpf' can't
be used to monitor system-wide bpf memory consumption yet.

Imma let memcg folks comment on the implementation. Hmm... I wonder how this
would tie in with the BPF memory allocator Alexei is working on.

What's the difference between bpf and total_bpf? Where's total_bpf
implemented? It doesn't seem to be anywhere. Please also update
Documentation/admin-guide/cgroup-v2.rst.

So, system-level accounting is usually handled separately as it's most
likely that we'd want the same stat at the system level even when cgroup is
not implemented. Here, too, it'd make sense to first implement system level
bpf memory usage accounting, expose that through /proc/meminfo and then use
the same source for root level cgroup stat.

Thanks.

BPF memory allocator is already in bpf-next [1].
It uses the same way to charge bpf memory into memcg, see also
get_memcg() in the BPF memory allocator, so it has been supported in
this patchset.

Ah, the total_* items are cgroup1-specific items. They also include
the descendants' memory.
This patchset supports both cgroup1 and cgroup2.

Sure, I will update the Document.

Sure, I will do it first. Thanks for your suggestion.
