[RFC PATCH v2 00/21] FUSE BPF: A Stacked Filesystem Extension for FUSE

[RFC PATCH v2 00/21] FUSE BPF: A Stacked Filesystem Extension for FUSE

[Daniel Rosenberg]

These patches extend FUSE to be able to act as a stacked filesystem. This
allows pure passthrough, where the fuse file system simply reflects the lower
filesystem, and also allows optional pre and post filtering in BPF and/or the
userspace daemon as needed. This can dramatically reduce or even eliminate
transitions to and from userspace.

For this patch set, I have removed the code related to the bpf side of things
since that is undergoing some large reworks to get it in line with the more
recent BPF developements. This set of patches implements direct passthrough to
the lower filesystem with no alteration. Looking at the v1 code should give a
pretty good idea of what the general shape of the bpf calls will look like.
Without the bpf side, it's like a less efficient bind mount. Not very useful
on its own, but still useful to get eyes on it since the backing calls will be
larglely the same when bpf is in the mix.

This changes the format of adding a backing file/bpf slightly from v1. It's now
a bit more modular. You add a block of data at the end of a lookup response to
give the bpf fd and backing id, but there is now a type header to both blocks,
and a reserved value for future additions. In the future, we may allow for
multiple bpfs or backing files, and this will allow us to extend it without any
UAPI breaking changes. Multiple BPFs would be useful for combining fuse-bpf
implementations without needing to manually combine bpf fragments. Multiple
backing files would allow implementing things like a limited overlayfs.
In this patch set, this is only a single block, with only backing supported,
although I've left the definitions reflecting the BPF case as well.
For bpf, the plan is to have two blocks, with the bpf one coming first.
Any further extensions are currently just speculative.

You can run this without needing to set up a userspace daemon by adding these
mount options: root_dir=[fd],no_daemon where fd is an open file descriptor
pointing to the folder you'd like to use as the root directory. The fd can be
immediately closed after mounting. This is useful for running various fs tests.

The main changes for v2:
-Refactored code to remove many of the ifdefs
-Adjusted attr related code per Amir's suggestions
-Added ioctl interface for responding to fuse requests (required for backing)
-Adjusted lookup add-on block for adding backing file/bpf
-Moved bpf related patches to the end of the stack (not included currently)

TODO:
override_creds to interact with backing files in the same context the daemon
would

Implement backing calls for other FUSE operations (i.e. File Locking/tmp files)

Convert BPF over to more modern version

[RFC PATCH v2 01/21] fs: Generic function to convert iocb to rw flags

[Daniel Rosenberg]

From: Alessio Balsini <balsini@google.com>

OverlayFS implements its own function to translate iocb flags into rw
flags, so that they can be passed into another vfs call.
With commit ce71bfea207b4 ("fs: align IOCB_* flags with RWF_* flags")
Jens created a 1:1 matching between the iocb flags and rw flags,
simplifying the conversion.

Reduce the OverlayFS code by making the flag conversion function generic
and reusable.

Adds structures which will be used to inform fuse about what it is being
stacked on top of. Once filters are in place, error_in will inform the

[RFC PATCH v2 04/21] fuse: Add fuse-bpf, a stacked fs extension for FUSE

[Daniel Rosenberg]

Fuse-bpf provides a short circuit path for Fuse implementations that act
as a stacked filesystem. For cases that are directly unchanged,
operations are passed directly to the backing filesystem. Small
adjustments can be handled by bpf prefilters or postfilters, with the
option to fall back to userspace as needed.

Fuse implementations may supply backing node information, as well as bpf
programs via an optional add on to the lookup structure.

This has been split over the next set of patches for readability.
Clusters of fuse ops have been split into their own patches, as well as
the actual bpf calls and userspace calls for filters.

[RFC PATCH v2 05/21] fuse-bpf: Add ioctl interface for /dev/fuse

[Daniel Rosenberg]

This introduces an alternative method of responding to fuse requests.
Lookups supplying a backing fd or bpf will need to call through the
ioctl to ensure there can be no attempts to fool priveledged processes
into inadvertantly performing other actions.

[RFC PATCH v2 06/21] fuse-bpf: Don't support export_operations

[Daniel Rosenberg]

In the future, we may choose to support these, but it poses some
challenges. In order to create a disconnected dentry/inode, we'll need
to encode the mountpoint and bpf into the file_handle, which means we'd
need a stable representation of them. This also won't hold up to cases
where the bpf is not stateless. One possibility is registering bpf
programs and mounts in a specific order, so they can be assigned
consistent ids we can use in the file_handle. We can defer to the lower
filesystem for the lower inode's representation in the file_handle.

[RFC PATCH v2 21/21] fuse-bpf: allow mounting with no userspace daemon

[Daniel Rosenberg]

When using fuse-bpf in pure passthrough mode, we don't explicitly need a
userspace daemon. This allows simple testing of the backing operations.

I hope there is a better way than this macro...
Haven't studied the patches enough to be able to suggest one.

Which tests did you run?

My recommendation (if you haven't done that already):
Add a variant to libfuse test_passthrough (test_examples.py):
@pytest.mark.parametrize("name", ('passthrough', 'passthrough_plus',
                           'passthrough_fh', 'passthrough_ll',
'passthrough_bpf'))

and compose the no_daemon cmdline for the 'passthrough_bpf' mount.

This gives pretty good basic test coverage for FUSE passthrough operations.

I've extended test_passthrough_hp() for my libfuse_passthrough patches [1],
but it's the same principle.

Thanks,
Amir.

Re: [RFC PATCH v2 00/21] FUSE BPF: A Stacked Filesystem Extension for FUSE

[Daniel Rosenberg]

I've been running the generic xfstests against it, with some
modifications to do things like mount/unmount the lower and upper fs
at once. Most of the failures I see there are related to missing
opcodes, like FUSE_SETLK, FUSE_GETLK, and FUSE_IOCTL. The main failure
I have been seeing is generic/126, which is happening due to some
additional checks we're doing in fuse_open_backing. I figured at some
point we'd add some tests into libfuse, and that sounds like a good
place to start.

I'm certainly open to suggestions there. Currently the main thing
stopping us from moving away from that macro are the four
functions/var args we pass in. We've thought about alternatives there,
but we haven't found one we like so far. Since we've refactored all
the uses of the macro into function calls, we can avoid most of it
now. The ugliest bit would be moving the var args into a struct and
passing it in as a void*. Then we could have all the function
signatures match and pass them as function pointers. The remaining
things we use the macro for could either be pushed into the struct, or
extra boilerplate around the function call.

Here is a branch of xfstests that should work with fuse and should not 
run "rm -fr /" (we are going to give it more testing this week).

Bernd, Daniel, Vivek,

Did you see LSFMMBPF 2023 CFP [1]?

Did you consider requesting an invitation?
I think it could be a good opportunity to sit in a room and discuss the
roadmap of "FUSE2" with all the developers involved.

I am on the program committee for the Filesystem track, and I encourage
you to request an invite if you are interested to attend and/or nominate
other developers that you think will be valuable for this discussion.

Thanks,
Amir.

Thanks a lot Amir, I'm going to send out an invitation tomorrow. Maybe 
Nikolaus as libfuse maintainer could also attend?


Thanks,

Since this summit is about kernel filesystem development, I am not sure
on-prem attendance will be the best option for Nikolaus as we do have
a quota for
on-prem attendees, but we should have an option for connecting specific
attendees remotely for specific sessions, so that could be great.

Two more notes:
1. We realize that companies are going through economic changes and that
    this may not be the best time to request travel approval or to be able to
    get it. This should not stop you from requesting to attend!
    Worse case, you can attend remotely. It is not the same experience, but
    it is better than not attending at all if you have something to
contribute to
    the discussion.
2. Bernd, I think you have some interesting WIP on "FUSE2" that the majority
    of fs developers are not aware of.
    It would be great if you can follow the instructions in CFP and also post
    a TOPIC suggestion to fsdevel, to get the discussion started ahead of
    the summit.
    Daniel, same request for FUSE BFP. The TOPIC suggestion should
    highlight the remaining open questions about design and API, which
    may be good to discuss in this forum.
    Please do not be intimidated by suggesting a TOPIC, you don't need
    to prepare any slides if you do not want to, nor to submit an abstract
    or anything of that sort.

Thanks,
Amir.

Not sure.  I think including non-kernel people might be beneficial to
the whole fs development community.  Not saying LSF is the best place,
but it's certainly a possibility.

Nikolaus, I don't even know where you're located.  Do you think it
would make sense for you to attend?

Thanks,
Miklos

Hi folks,

I'm located in London. 

I've never been at LHS, so it's hard for me to tell if I'd be useful there or not. If there's interest, then I would make an effort to attend. 

Are we talking about the event in Vancouver on May 8th?

Best,
-Nikolaus

Yes, that's the one.

I'd certainly think it would be useful, since there will be people
with interest in fuse filesystems and hashing out the development
direction involves libfuse as well.

Here's the CFP and attendance request if you are interested:

Attending LFS (was: [RFC PATCH v2 00/21] FUSE BPF: A Stacked Filesystem Extension for FUSE)

[Nikolaus Rath]

Hi folks,

I've looked into this in more detail.  

I wouldn't be able to get the travel funded by my employer, and I don't think I'm a suitable recipient for the Linux Foundation's travel fund. Therefore, I think it would make more sense for me to attend potentially relevant sessions remotely.

If there's anything I need to do for that, please let me know. Otherwise I'll assume that at some point I'll get a meeting invite from someone :-).

If there's a way to schedule these sessions in a Europe-friendly time that would be much appreciated!

Best,
-Nikolaus

Please use the Form in the CFP link to request to attend and specify
that you can
only  attend remotely.

This will get you subscribed to information about relevant sessions
and how to connect.

Will do my best to take that into consideration :)

Thanks,
Amir.
