Having just been upgraded to Windows 10 Insider Preview Build 18922.rs_prerelease.190614-1427, I decided to have another play with WSL, and trying to make it interoperate with OpenZFS.

If I launch a Ubuntu instance, it doesn't even attempt to add a ZFS dataset to the set of mountpoints (in /mnt), and if I create an NTFS junction, or symbolic link, to my ZFS directory, on an NTFS partition, before attempting to sneak in, using cd /mnt/c/Canvio, it looks like it does try to access our volume, before bailing with the following FileSpy output:

… as well as the error:

-bash: cd: /mnt/c/Canvio: Function not implemented

There's supposed to be an option to passthrough metadata, and enumerate all drives, according to https://devblogs.microsoft.com/commandline/automatically-configuring-wsl/ (which allegedly works with WinBTRFS, somehow).

Curiously, with the latest release of LxRunOffline (3.4.0), it doesn't complain about case-sensitivity problems (even on a "mixed" sensitivity dataset - older Windows/LxRunOffline versions used to complain about us not implementing the new NTFS case-sensitivity flag), but it does complain about being unable to create OS/2-style extended attributes, if I try to move a Ubuntu installation, from NTFS, to ZFS:

I:\LxRunOffline-v3.4.0>LxRunOffline.exe m -n Ubuntu -d H:\WSLBuntu
[ERROR] Couldn't set the extended attribute "LXATTRB" of the file or directory "\\?\H:\WSLBuntu\rootfs\".
Reason: {Access Denied}
A process has requested access to an object, but has not been granted those access rights.

I assume that unlike NTFS streams, this type of metadata either is unsupported, or broken?

For writing the metadata, FileSpy reports:

I haven't gotten around to seeing what happens, with WSL2 instances, yet, though...

Unsurprisingly, it looks like we can't set that case-sensitivity flag, since it's not supported, but I'm not sure if we always need it, for WSL, on other versions of Windows:

H:\>fsutil.exe file setcasesensitiveinfo CaseTest1.txt
Error:  Access is denied.
A local NTFS volume is required for this operation.

No joy with queryEA, either:

H:\>fsutil.exe file queryEA WSLBuntu
Error:  The directory is not a subdirectory of the root directory.
A local NTFS volume is required for this operation.

Did find some interesting info at microsoft/WSL#3865, and microsoft/WSL#2954, regarding the new NTFS additions, to support WSL, though.

I wonder if it simply requires IOCTL_MOUNTDEV_QUERY_STABLE_GUID although I don't think WinBTRFS implemented it either. But seeing NotImplemented is usually the clue I look for when something doesn't work.

Ah no, they do support it - I should implement that then and we can try again.

Looks like invoking the "wsl" command, vs. launching the instance from the "Ubuntu" Start Menu item will cause it to load in the wsl.conf file, and show "metadata", in the mount table, for some of my volumes (I can access the WinBTRFS-accessible Linux installation, on this machine's internal eMMC), but I still can't access the ZFS datasets, although it does "tickle" them, according to FileSpy:

FWIW, on BTRFS, the way Ubuntu is launched makes a difference, as to what happens, if I do ls /mnt/e

root@DESKTOP-E3OG0KB:~# ls /mnt/e
ls: cannot access '/mnt/e/System Volume Information': Permission denied
'$RECYCLE.BIN'   @   @home   PoolHistory128.txt  'Program Files'  'System Volume Information'

(Launched with "wsl")

With the other technique, it used to complain with some cryptic error, that I can't trigger, anymore.

If I add the following to /etc/wsl.conf, and restart WSL, I get a /mnt/i, but no files appear, if I attempt to list its contents:

[automount]
enabled = true
options = "metadata"
mountFsTab = false

If enabled = false is set, no ZFS mounts appear in /mnt, at all.

That IOCTL_VOLSNAP_QUERY_NAMES_OF_SNAPSHOTS is interesting, I'll see if I can reply to it in a valid way, maybe it'll get a little further

I wonder if they're related to Windows's "Previous Versions"/"Shadow Copies" feature, somehow? (I had some issues, with Windows's backup utilities failing to work, for a long time, since it was having problems with taking some kind of volume snapshots).

(I know that Samba can be configured to passthrough specially-named ZFS snapshots, as "Shadow Copies", with some finessing - which might also be useful to do, with native ZFS snapshots, under "real Windows", at a risk of opening ourselves up to ransomware potentially trying to trash ZFS snapshots)

Dunno why it still says "Not implemented", for IOCTL_MOUNTDEV_QUERY_STABLE_GUID, when you've just gone to the trouble of implementing it, unless there's some more IOCTL flags, that it's complaining about? (I'm using my main disk, on my Mac, at the moment, since I keep getting a BSOD, when trying to mount it, under Windows, and Linux keeps hanging, randomly)...

I find it weird, how Google UK has basically no indexed results, for IOCTL_VOLSNAP_QUERY_NAMES_OF_SNAPSHOTS, beyond post-mortems of malware infestations (although Bing, of all things, turns up some stuff from OSR, and MSDN/TechNet).

Some undocumented, custom IOCTL, used only by Microsoft products, or Windows itself?

Hmm ok, there are three paths for ioctls in ZFS - the disk, then filesystem and finally ZFS ioctls. Ie, Windows talking to the virtual disk device - I added the call here, as that is what my example called.

filesystem is the requests like mkdir/rmdir, read/write etc. I suspect maybe it called IOCTL_MOUNTDEV_QUERY_STABLE_GUID here as well, so I'll add the call here too.

Last ioctl is just ZFS command line tools issuing create snapshot, attach disk etc. Windows can't call these.

As for VOLSNAPS, looks like I should reply with

// Output buffer for IOCTL_VOLSNAP_QUERY_NAMES_OF_SNAPSHOTS and
typedef struct _VOLSNAP_NAMES {
    ULONG   MultiSzLength;
    WCHAR   Names[1];
} VOLSNAP_NAMES, *PVOLSNAP_NAMES;

I absolutely love that you include the FileSpy, saves me no end of time! You should wrap them in the magic lines

Here obviously there should be no space in the three backticks, and it needs that weird blank line between the <p> and start of code three-backticks.

Yeah, it's the least that I can do, considering that I can't guarantee that everyone's using the same versions of stuff, or the same hardware configurations, or that some third-party software won't present a unique problem, that doesn't expose itself, on a virgin Windows installation.

I put up a new debug - with the stable_guid in fsIoctl, and a volsnap_query_names_of_snapshots analogue, that just returns zero and A-OK.

Heh, it looks like the weird WinBTRFS error has surfaced, when listing mountpoints, but it still doesn't mount a ZFS dataset:

Moving out the "i" directory, from /mnt (which doesn't have anything on it, but somehow contains local files), doesn't make a difference, either way.

Trying to get into the symlinked dataset, produces a very clean log, though:

Not sure if it becomes a limitation in WSL itself, then...

As an aside, trying to get into the BTRFS volume, gives us that weird ls: cannot open directory '.': Value too large for defined data type error:

It feels like something is dropping, or filtering events, though.

If NTFS can return not implemented, then we can too, and it is something else wrong.

Horribly bloated, even after trying to exclude a ton of calls made by various background services (e.g. the disk indexer, and svchost), but I managed to get a trace of what happens, when trying to launch WSL, on the NTFS system volume, when it goes to iterate for things to mount, at least.

Really hard to strike a balance between making a useful log, that contains everything necessary to debug stuff, without either making it so overwhelming, as to be a hinderance, or inadvertently leaking private information, it seems, though.

Yep that it is. FileSpy is good for comparing, but the internal ZFS debug log shows more logic decisions we make.

Shame that Windows's debugging, and reverse-engineering tools are so dire, compared with the ones on modern UNIXes (there's supposed to be a DTrace port, but it apparently requires you to attach a second machine, as a debugging terminal, and jump through a bunch of hoops, to even work!) - even having something like "strace" would be a massive boon, for figuring out how stuff works.

Doesn't help that the OS itself, is so intricately bloated, that it performs like a whale, in a VM, either.
