[PATCH v2 00/20] btrfs: add fscrypt integration

[Sweet Tea Dorminy]

This is a changeset adding encryption to btrfs.

Last October, Omar Sandoval sent out a design document for having fscrypt
integration with btrfs [1]. In summary, it proposes btrfs storing its
own encryption IVs on a per-file-extent basis. fscrypt usually encrypts
files using an IV derived from per-inode information; this would prevent
snapshotting or reflinking or data relocation for btrfs. We have
refined this into a fscrypt extent context object, opaque to the
filesystem, which fscrypt uses to generate an IV associated with each
block in an extent. Thus, all the inodes sharing a particular
key and file extent may decrypt the extent.

This series implements this integration for the simple
case, non-compressed data extents. Followup changes will allow
encryption of compressed extents, inline extents, and verity items, and
will add tests around subvolume encryption. This series should provide
encryption for the simplest cases, but this series should not be used in
production, as there are likely bugs.
 
Preliminary btrfs-progs changes are available at [2]; fstests changes
are available at [3].

Changelog:

v2:
 - Amended the fscrypt side to generically add extent contexts,
   hopefully as per Eric Biggers' past comments. IVs are now entirely
   abstracted within an extent context, and there is no longer a new
   encryption policy, as DIRECT_KEY sufficiently encapsulates the
   needs of extent-based encryption. Documented its usage in btrfs
   briefly in the documentation. 
 - Adjusted the btrfs side to deal in opaque extent contexts. Improved
   optimization to skip storing inode contexts if they are the same as
   the inode's root item's inode context.
 - Combined 'add fscrypt operation table to superblock' into 'start
   using fscrypt hooks'.

[PATCH v2 01/20] fscrypt: expose fscrypt_nokey_name

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

btrfs stores its data structures, including filenames in directories, in
its own buffer implementation, struct extent_buffer, composed of
several non-contiguous pages. We could copy filenames into a
temporary buffer and use fscrypt_match_name() against that buffer, such
extensive memcpying would be expensive. Instead, exposing
fscrypt_nokey_name as in this change allows btrfs to recapitulate
fscrypt_match_name() using methods on struct extent_buffer instead of
dealing with a raw byte array.

[PATCH v2 02/20] fscrypt: add flag allowing partially-encrypted directories

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

Creating several new subvolumes out of snapshots of another subvolume,
each for a different VM's storage, is a important usecase for btrfs.  We
would like to give each VM a unique encryption key to use for new writes
to its subvolume, so that secure deletion of the VM's data is as simple
as securely deleting the key; to avoid needing multiple keys in each VM,
we envision the initial subvolume being unencrypted. However, this means
that the snapshot's directories would have a mix of encrypted and
unencrypted files. During lookup with a key, both unencrypted and
encrypted forms of the desired name must be queried.

To allow this, add another FS_CFLG to allow filesystems to opt into
partially encrypted directories.

I'm still trying to wrap my head around what this part involves exactly.  This
is a pretty big change in semantics.

Could this be moved to the end of the patchset, or is this a fundamental part of
the btrfs fscrypt support that the rest of your patchset depends on?  I'd think
it would be a lot easier to review if this change was an add-on at the end.

One thing to keep in mind is that FS_IOC_SET_ENCRYPTION_POLICY failing on
nonempty directories can actually be very useful, since it makes it possible to
detect bugs where people create files in encrypted directories (expecting that
they are encrypted) before an encryption policy actually gets assigned.  Since
FS_IOC_SET_ENCRYPTION_POLICY fails in that case, such bugs can be detected and
fixed.

If it succeeds, then everything would just silently work and some files wouldn't
be encrypted as intended.  That's kind of scary.

It might be warranted to use an encryption policy flag to explicitly indicate
that mixing encrypted and unencrypted files is being allowed.

I agree that this has risks of inadvertent misuse in that fashion.

The usecase I'm oriented towards is: someone builds an unencrypted 
subvolume with a container base filesystem, takes several snapshots of 
the subvolume, starts a container on each subvolume, and has each 
container encrypt its designated subvolume going forward with a 
different key. This usecase needs some way to mark a subvolume/directory 
already containing files as encrypted going forward; I've had a hard 
time coming up with a way to both protect users against such accidental 
misuse, but also allow this container usecase.

Could it be sufficient to check either empty or read-only, something 
like (is_empty_dir(inode) || (FS_CFLG_PARTIAL && !inode_permission(...,

unencrypted data, since they've taken an action to make the directory 
read-only, until they've set a policy and key and turned the directory 
read-write again.

In this usecase, you didn't mention if the original subvolume is
encrypted, assuming it is not, so this usecase is the same as mentioned
in the design document. Now, in this usecase, what happens if the
original subvolume is encrypted? Can we still avoid the multiple keys?
How is that going to work? Or we don't yet support subvolumes out of
snapshots of another encrypted subvolume?

Count this as the first official "email triggered by Plumbers" I
suppose, but I've been looking forward to Btrfs encryption for Fedora
for a variety of use-cases:

* Converting a disk from unencrypted to encrypted without reinstalling[1]
* Encrypting system and user data with different credentials[2][3]
* Mass managed systems with dual-credential encryption (one rooted in
org, other by user)[1]

The way I envision Fedora's usage of this feature going is as follows:

The system is shipped (OEM install; e.g. Lenovo, Slimbook, etc.) or
installed without encryption (from Anaconda). The firstboot process
helps the user get setup, and asks if they want disk encryption
(provided there is no policy forcing it on). If the answer is yes,
then the root subvolume and the home subvolume are configured to be
encrypted using the on-board secure enclave (TPM or whatever). When
the user creation step occurs, if disk encryption was set on earlier,
then the user subvolume inside the home subvolume gets configured to
be encrypted using the login credentials. If it wasn't set on earlier,
we could also still offer to encrypt the user data here. If this is a
mass-managed system, an additional decryption key would be available
for the system manager to use in the event of credential loss, damaged
TPM, etc.

For the cloudy scenario, we'd probably provide tools to orchestrate
this from cloud-init for confidential computing stuff too.

For all this to work, I expect the following:

* Encryption to support *somehow* any number of decryption keys/methods
* Nesting of subvolumes with differing encryption methods
* The ability to blindly backup and restore subvolumes without needing
to decrypt

On a personal system, I expect at most two credentials in use: one
keyed to the system and one keyed to the user. For a corporate/mass
managed system, I expect a third one: one keyed to the management
platform. This is necessary because in a lot of jurisdictions, you
don't necessarily own the data on your corporate laptop, and the owner
has the right to be able to access that data. But a more prosaic or
banal reason is that people forget their credentials and being able to
reset them without losing all their data is usually a good thing. :)

Hopefully I've transcribed what I said properly into this email. :)

[PATCH v2 03/20] fscrypt: add fscrypt_have_same_policy() to check inode compatibility

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

Btrfs will need to check whether inode policies are identical for
various purposes: if two inodes want to share an extent, they must have
the same policy, including key identifier; symlinks must not span the
encrypted/unencrypted border; and certain encryption policies will allow
btrfs to store one fscrypt_context for multiple objects. Therefore, add
a function which allows checking the encryption policies of two inodes
to ensure they are identical.

These things can return random errors, so you're mixing bool with errnos, and
then you're using this function as if it only returns bools.  I'm not sure what
the best thing to do is here for consistency, maybe return 0 for no match, 1 for
match, and then err and handle it that way.  At the very least the callers need
to be updated to handle the errors.  But I really don't like the mixing of bool
returns with ERRNO returns.  An alternative would be to have a helper do the
getting of the policies which will give you the errno's appropriately, and then
do the call to fscrypt_policies_equal with the policies you grab.  Thanks,

Josef

[PATCH v2 04/20] fscrypt: allow fscrypt_generate_iv() to distinguish filenames

[Sweet Tea Dorminy]

With the introduction of extent-based file content encryption, filenames
and file contents might no longer use the same IV generation scheme, and
so should not upass the same logical block number to
fscrypt_generate_iv(). In preparation, start passing U64_MAX as the
block number for filename IV generation, and make fscrypt_generate_iv()
translate this to 0 if extent-based encryption is not being used.

I had to go look at how you used this, because it seemed superflous to me, but
it's because later you put the IV generation stuff above this particular bit of
code.  You say that we set it to 0 if extent-based encryption is not being used,
but looking at this in vimdiff I don't know where that's going to be.  So
perhaps something like

I will be adding code to generate IV's for extent-based encryption before
falling through to the other policy types, and I will check for U64_MAX to skip
the extent-based generation.  At this point we'll want to switch back to 0 for
filenames.

Or some other such description.  Thanks,

Josef

[PATCH v2 05/20] fscrypt: add extent-based encryption

[Sweet Tea Dorminy]

Some filesystems need to encrypt data based on extents, rather than on
inodes, due to features incompatible with inode-based encryption. For
instance, btrfs can have multiple inodes referencing a single block of
data, and moves logical data blocks to different physical locations on
disk in the background; these two features mean inode or
physical-location-based policies will not work for btrfs.

This change introduces fscrypt_extent_context objects, in analogy to
existing context objects based on inodes. For a filesystem which uses
extents, a new hook provides a new fscrypt_extent_context. During file
content encryption/decryption, the existing fscrypt_context object
provides key information, while the new fscrypt_extent_context provides
IV information. For filename encryption, the existing IV generation
methods are still used, since filenames are not stored in extents.

As individually keyed inodes prevent sharing of extents, such policies
are forbidden for filesystems with extent-based encryption.

I really like how this abstracts away the encryption details from the
filesystem.

This makes it sounds like all filesystems that store allocations as
extents should define these, but ext4 (for example) uses extents but is
fine with inode-based encryption policies. Perhaps this can say
something like "A filesytem can opt into the extent-based encryption
policy by defining new hooks that manage a new fscrypt_extent_context."

This ends up forcing Btrfs to use Adiantum. However, I imagine that most
users would prefer to use AES if their CPU has AES instructions. From
what I understand, it should still be possible to use the AES encryption
modes with extent contexts, correct? We just need to decide how to make
that work with the encryption policy flags. I see a couple of options:

1. We add a specific FSCRYPT_POLICY_FLAG_EXTENT_BASED or something like
   that which the user must specify for filesystems requiring
   extent-based encryption.
2. The "default" mode (i.e., none of DIRECT_KEY, IV_INO_LBLK_64, nor
   IV_INO_LBLK_32 are specified) automatically opts into extent-based
   encryption for filesystems requiring it.

Either way, we should probably still disallow IV_INO_LBLK_64 and
IV_INO_LBLK_32 since neither of those make sense with per-extent IVs.

I'd love to hear what Eric would prefer here.

Thanks,
Omar

Newline between declarations and code, and since you use the warnon i'd do

int ret;

I'm on vacation at the moment, but I've been thinking about this patchset and
I'll leave some quick high-level feedback.

I think that you've sort of ended up with something reasonable in this patch,
though maybe not for exactly the reasons you thought, and it still needs to be
tweaked a bit.

Thinking abstractly, an encryption policy indicates that a set of files is
encrypted with a particular key.  That set of files contains a set of objects
containing "file contents", each containing a sequence of file contents blocks.
File contents encryption is the encryption that is applied to these objects.

With other filesystems, the "file contents objects" are inodes.  With btrfs, the
"file contents objects" are extents.

I think it's fair to say that this is just a difference in the filesystems, and
it doesn't need to be explicitly indicated in the encryption policy.

What *is* super important, though, is to keep the cryptography consistent.

Consider the existing default setting, which derives a per-inode key from the
master key and a per-inode nonce, and sets the IV to the offset into the inode.
There is a natural mapping of that to extent-based encryption: derive a
per-extent key from the master key and a per-extent nonce, and set the IV to the
offset into the extent.

But you haven't actually implemented that.  I assume that you've discarded
per-extent keys as infeasible?

If that's the case, then the alternative is to do file contents encryption with
a per-mode key, using an IV generation method that makes the IVs identify both
the file contents object *and* the offset into it, rather than just the latter.

The existing methods for that are DIRECT_KEY, IV_INO_LBLK_32, and
IV_INO_LBLK_64.  DIRECT_KEY uses a 16-byte nonce to identify the file contents
object.  IV_INO_LBLK_32 and IV_INO_LBLK_64 use a filesystem-assigned ID;
currently this ID is inode number, but if they were to be applied to
extent-based encryption, it would be an "extent number" instead.

So if you do want to implement the DIRECT_KEY method, the natural thing to do
would be to store a 16-byte nonce along with each extent, and use the DIRECT_KEY
IV generation method as-is.  It seems that you've done it a bit differently; you
store a 32-byte nonce and generate the IV as 'nonce + lblk_num', instead of
'nonce || lblk_num'.  I think that's a mistake -- it should be exactly the same.

If the issue is that the 'nonce || lblk_num' method doesn't allow for AES-XTS
support, we could extend DIRECT_KEY to do 'nonce + lblk_num' *if* the algorithm
has a 16-byte IV size and thus has to tolerate some chance of IV reuse.  Note
that this change would be unrelated to extent-based encryption, and could be
applied regardless of it.

Side note: please don't use the phrase "file-based encryption" to distinguish
from "extent-based encryption", as "file-based encryption" is already in use to
distinguish from block-device based encryption.  (See e.g. all the Android
documentation that refers to file-based encryption.)  Maybe use "inode-based
encryption", or "inode-based file contents encryption" to be extra clear.

[PATCH v2 06/20] fscrypt: document btrfs' fscrypt quirks.

[Sweet Tea Dorminy]

As btrfs has a couple of quirks in its encryption compared to other filesystems, they
should be documented like ext4's quirks. Additionally, extent-based
contents encryption, being wholly new, deserves its own section to
compare against file-based contents encryption.

[PATCH v2 07/20] btrfs: store directory's encryption state

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

For directories with encrypted files/filenames, we need to store a flag
indicating this fact. There's no room in other fields, so we'll need to
borrow a bit from dir_type. Since it's now a combination of type and
flags, we rename it to dir_flags to reflect its new usage.

The new flag, FT_FSCRYPT, indicates a (perhaps partially) encrypted
directory, which is orthogonal to file type; therefore, add the new
flag, and make conversion from directory type to file type strip the
flag.

You're already doing this just for the thing below, why not just do

		u8 ftype;

		ftype = btrfs_dir_flags_to_ftype(btrfs_dir_flags(leaf, di);

then here do

		put unaligned(fs_ftyp_to_dtype(ftype), &entry->type);

to make it a little cleaner.  Thanks,

[PATCH v2 08/20] btrfs: use fscrypt_names instead of name/len everywhere.

[Sweet Tea Dorminy]

For encryption, the plaintext filenames provided by the VFS will need to
be translated to ciphertext filenames on disk. Fscrypt provides a struct
to encapsulate a potentially encrypted filename, struct fscrypt_name.
This change converts every (name, len) pair to be a struct fscrypt_name,
statically initialized, for ease of review and uniformity.

Is there some clear boundary where the name needs to be encoded or
decoded? I don't think we should use fscrypt_name in so many functions,
namely internal helpers that really only care about the plain name +
length. Such widespread use fscrypt structure would make it hard to
synchronize with the user space sources.

What we could do to ease the integragtion with the fscrypt name is to
use the qstr structure, ie. something that's easily convertible to the
fscrypt_name::usr_fname.

This for example is a primitive helper that just hashes the correct
bytes and does not need to know anything about whether it's encrypted or
not. That should be set up higher in the call chain.

And here it needs extra structure just to pass plain strings.

Please don't use this construct to intialize compounds, we don't use it
anywhere. There are more examples for other structures too.

Please keep the specifiers and type on the same line as the function
name, the parameters can slightly overfrlow the 80 char limit if it
avoids a line break, otherwise the patameters go on the next line.

[PATCH v2 09/20] btrfs: setup fscrypt_names from dentrys using helper

[Sweet Tea Dorminy]

Most places that we create fscrypt_names, we are doing so from a dentry.
Fscrypt provides a helper for this common pattern:
fscrypt_setup_filename() initializes a filename to search for from a
dentry, performing encryption of the plaintext if it can and should be
done. This converts each setup of a fscrypt_name from a dentry to use
this helper; at present, since there are no encrypted directories,
nothing goes down the filename encryption paths.

[PATCH v2 10/20] btrfs: factor a fscrypt_name matching method

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

Now that everything in btrfs is dealing in fscrypt_names, fscrypt has a
useful function, fscrypt_match_name(), to check whether a fscrypt_name
matches a provided buffer. However, btrfs buffers are struct
extent_buffer rather than a raw char array, so we need to implement our
own imitation of fscrypt_match_name() that deals in extent_buffers,
falling back to a simple memcpy if fscrypt isn't compiled. We
can then use this matching method in btrfs_match_dir_item_name() and
other locations.

This also provides a useful occasion to introduce the new fscrypt file
for btrfs, handling the fscrypt-specific functions needed.

The code is fine, but I was very confused about why we do this sha256 thing.
Perhaps point at the code for fscrypt_nokey_name and indicate that it exists to
be interoperable with no-key actions on the file system.  Thanks,

Josef

The wiki is incorrect.  The SPDX tag deals with the licensing tags
only.  It is not a replacement for the copyright notice in any way, and
having been involved with Copyright enforcement I can tell you that
at least in some jurisdictions Copytight notices absolutely do matter.

I believe you and can update the wiki text so it's more explicit about
the license an copyright.

Otherwise I don't see much point in the copyright notices unless they're
complete list of every person and company that touched that file. With
that we haven't been adding that to new files for some time and I want
to be consistent with that. In each case the patch author was asked to
resubmit without the notice. It worked so far.

If not, either the patch will be respectfully rejected or somebody
else creates the file first and then the patch applied.

Can you update the wiki text to remove "SPDX" from the heading and 
remove the sentence stating, "An initiative started in 2017 [1] aims to 
unify licensing information in all files using SPDX tags, this is driven 
by the Linux Foundation."

Thanks,

This is a very good point.

The current Wiki page for btrfs (linked above) says:

…

This is admittedly a very tough problem to solve.  Nevertheless, the concern
that I have with that recommendation above is that it gives copyright holders
whose notices are grandfathered an additional notice preservation that new
copyright holders don't have equal access to.  It's particular problematic
because new contributors are unable to have contributions included unless
they remove copyright notices.

Again, I realize the trade-offs are really tough here; removing existing
copyright notices without explicit permission is a *serious* problem (both a
GPL violation and a statutory violation of copyright generally in many
jurisdictions).  OTOH, a list of every last copyright holder is painfully
unwieldy — even if you combine it into a single location.

Most importantly, I want to point out the bigger, implicit trade-off here
that some may not realize.  If you relying on Git history to have copyright
notice information, it does make the entire Git repository a required part of
the complete, corresponding source under GPLv2.  This will become even more
certain when contributors are being told that they may *not* include a
copyright notice and that their copyright information will appear in metadata
instead.  They can reasonably interpret the “appropriately publish on each
copy an appropriate copyright notice” in GPLv2§1 to mean the copyright
notices in the Git metadata.

All of that seems accurate to me.  What part is not accurate?

Splitting the information to talk about copyright and license separately
seems a good idea, but removing accurate explanations doesn't seem like a
good idea to me …

I've expanded the page hopefully correcting the confusion. It has 3
sections, about spdx, about copyright and the community perspective.

Thanks for the reply.  Oh well, so we basically don't have good options.

I can consider that if you tell me why I should do that, but I don't
find anything wrong with the sentence (and I wrote it originally). It's
merely stating that something happened and points to a well known linux
kernel related web site with more details about it.

I agree, SPDX != copyright, and they should probably be in different 
paragraphs in the wiki because it's misleading as it stands.

Signed-off-by is targeted at declaring that you have permission to put 
this code into this project, which is somewhat different from copyright.

For Meta code, I'm happy to use the git history method.  But, I'm not 
completely comfortable with enforcing that on other companies or 
individuals unless it's common practice elsewhere in the kernel.

[PATCH v2 11/20] btrfs: disable various operations on encrypted inodes

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

Initially, only normal data extents, using the normal (non-direct) IO
path, will be encrypted. This change forbids various other bits:
- allows reflinking only if both inodes have the same encryption status
- disables compressing encrypted inodes
- disables direct IO on encrypted inodes
- disable inline data on encrypted inodes

I'm not sure if we want the IS_ENCRYPTED as an explicit check or put it
to check_direct_IO, but probably to make it obvious that direct io does
not work with it a separate check is ok.

Yeah as we have something similar for verity.

The comment fits on one line (and slight 80 chars overflow is ok).

[PATCH v2 12/20] btrfs: start using fscrypt hooks.

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

In order to appropriately encrypt, create, open, rename, and various symlink
operations must call fscrypt hooks. These determine whether the inode
should be encrypted and do other preparatory actions. The superblock
must have fscrypt operations registered, so implement the minimal set
also.

Yes, and there's a fstest, generic/576, checking the hooks are in the 
right order.

In order to use them at the same time, you'd need to implement encryption of the
verity metadata, which it appears you haven't done yet.  So for now it can't be
allowed by btrfs.  ext4 and f2fs get the verity metadata encryption "for free"
because they store it appended to the file contents.  That's why ext4 and f2fs
allow fscrypt+fsverity together.  However, btrfs stores the verity metadata
separately, so it would need to handle encrypting it explicitly.

[PATCH v2 13/20] btrfs: add fscrypt_context items.

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

In order to store per-inode information such as the inode nonce and the
key identifier, fscrypt stores a context item with each encrypted inode.
This can be implemented as a new item type, as fscrypt provides an
arbitrary blob for the filesystem to store.

This also provides a good place to implement full-subvolume encryption:
a subvolume flag permits setting one context for the whole subvolume.
However, since an unencrypted subvolume would be unable to read
encrypted data, encrypted subvolumes should only be snapshottable to
other encrypted subvolumes.

Please use the following for key initialization.

	key.objectid = ...;
	key.type = ...;
	key.offset = ...;

This kind of initialization in the declaration block is ok, possibly
with only the simple initializers like btrfs_ino or normal constants.

Do we want to print that to the log? There are several EXDEV causes,
only another one prints a message and I think it should not.

The context is per inode, so OK the key is needed and the number is
leaving enough space in case we'd need to add more.

I prefer the

> +	if (ret)

Use btrfs_release_path, and then use btrfs_insert_empty_item() so you don't have
to re-allocate another path.  In fact this whole thing can be done like this

ret = search;
if (ret < 0) {
	goto out;
} else if (ret == 1) {
	btrfs_release_path(path);
	ret = btrfs_insert_empty_item();
	if (ret < 0)
		goto out;
}

leaf = path->nodes[0];
ptr = btrfs_item_ptr_offset(leaf, path->slots[0]);
write_extent_buffer(leaf, ctx, ptr, len);
btrfs_mark_buffer_dirty(leaf);
btrfs_release_path(path);

because the bit below still needs to happen, the iversion needs to change and
such even if we already have the context because we changed the context of the
inode.

Put

if (ret)
	btrfs_abort_transaction(trans, ret);

here because we'll need to abort the transaction if there was an error at this
point.  The error handling needs to be completely reworked, because we really
only need to abort if we have an error after we've inserted the context, any of
the errors before we do that are recoverable so we don't need to abort for that.

Additionally we always end the transaction.  The abort just aborts, it doesn't
end the transaction.

Ok never mind the bit above about aborting the transaction if (fs_data) since
your'e doing it here.  Thanks,

[PATCH v2 14/20] btrfs: translate btrfs encryption flags and encrypted inode flag.

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

In btrfs, a file can be encrypted either if its directory is encrypted
or its root subvolume is encrypted, so translate both to the standard
flags.

[PATCH v2 15/20] btrfs: store a fscrypt extent context per normal file extent

[Sweet Tea Dorminy]

In order to encrypt data, each file extent must have its own persistent
fscrypt_extent_context, which is then provided to fscrypt upon request.
This is only needed for encrypted extents and is of variable size on
disk, so file extents must additionally keep track of their actual
length.

FSCRYPT_EXTENT_CONTEXT_MAX_SIZE is 33 and btrfs_fscrypt_extent_context
is part of extent_map, that's quite common object. Random sample from my
desktop right now is around 800k objects so this is noticeable. Needs a
second look.

What does 2 mean? It should be some symbolic define with explanation as
it's defining on-disk format.

And another embedded btrfs_fscrypt_extent_context, that can also get a
lot of slab objects.

I could certainly define fscrypt_extent_context's as a separate btree 
object type, and/or have them be separately allocated and just have a 
pointer in the various structures to keep track of them. I didn't have a 
separate object for them since its only a 17 or 33 byte object (at 
present) on a per-btrfs_file_extent basis, but maybe that would be 
better?

I could also #ifdef CONFIG_FS_ENCRYPTION the member in each structure, 
if that would help over and beyond either of the previous things.

btrfs_ordered_extent is in memory so I don't know what you mean by a
btree object here, that's used for on-disk structures. All the new
fscrypt code adds a lot of stack space and increases data structures but
that's something that needs to be effectively, so if the pointers can be
shared then please find a way. I still don't have the whole picture so
can't say what would be best, there are still other things to address so
once that's done we can focus on the memory consumption. You can keep it
as is for now but keep notes that it needs another look later.

I think all the fscrypt related code should be behind ifdef
CONFIG_FS_ENCRYPTION, so the struct members too.

[PATCH v2 16/20] btrfs: Add new FEATURE_INCOMPAT_FSCRYPT feature flag.

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

As fscrypt files will be incompatible with older filesystem versions,
new filesystems should be created with an incompat flag for fscrypt.

Shouldn't this flag be named "encrypt", to be consistent with the other

[PATCH v2 17/20] btrfs: reuse encrypted filename hash when possible.

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

For encrypted fscrypt_names, we can reuse fscrypt's precomputed hash of
the encrypted name to generate our own hash, instead of rehashing the
unencrypted name (which may not be possible if it's a nokey name).

Can you please describe how this works when the key is not available?

[PATCH v2 18/20] btrfs: adapt directory read and lookup to potentially encrypted filenames

[Sweet Tea Dorminy]

From: Omar Sandoval <osandov@osandov.com>

When filenames can be encrypted, if we don't initially match a desired
filename, we have to try decrypting it with the directory key to see if
it matches in plaintext. Similarly, for readdir, we need to read
encrypted directory items as well as unencrypted.

You have this same work in the delayed inode stuff, the only exception is that
you don't do the hash thing.  I assume with the delayed inode that
fscrypt_has_encryption_key() would be true, so you could stuff all this in a
helper and use the helper from both places?  Thanks,

Patch 8 is large and dull, and bounced from linux-fscrypt@ for size, but 
b4 gets it for me. b4 -p linux-fscrypt recreates the missing [8/20]; is 
it possible that option is set somewhere in your configuration?

I did a quick pass to check if there's anything that could be merged to
6.1 as preparatory, the fname is a candidate but I've also seen random
coding style issues that I'd like to get fixed first.

One thing I've noticed is that the incompat bit is only defined but not
used anywhere. Any functional change should be guarded behind it, and
once the implementation is complete the enabling part is in a separate
patch.

Regarding the build config options, I assume that the fscrypt support is
optional, so it should build with and without the option. I'm not sure
I've see enough ifdefs for that. For such features there should be a
line in btrfs_print_mod_info, like we have eg. for verity.

I'll post other comments under the patches.
