CIFS Mount Failed, Error 22

hello,

I'm trying to connect to a samba share and keep getting error 22, upon checking the logs, this is what I get:

Re: CIFS Mount Failed, Error 22

Upstream bug. I'm affected as well.
https://lore.kernel.org/all/87edz63t11.fsf@cjr.nz/T/
culprit: https://git.kernel.org/pub/scm/linux/ke … eb81c765fe

I'm using gvfs-smb (userspace) as a workaround atm.
Server 4.14.7. Client 4.16.2. Kernel 5.18.8.

Maniaxx, thanks!

I never used gvfs-smb, is there a guide/reference you can help me with as to temp mount this shares?

Thanks!

Re: CIFS Mount Failed, Error 22

An easy way is probably via file manager:
https://wiki.archlinux.org/title/Samba# … figuration

5.18.9 has no fix.
https://git.kernel.org/pub/scm/linux/ke … nux-5.18.y

Re: CIFS Mount Failed, Error 22

Maniaxx, that's good info.

based on that I decided to instead use the LTS kernel for the meantime and its indeed, "fixed".

Many thanks for saving me a night of head scratching!

I am affected with this on shares from OpenMediaVault (NAS).
Shares from Windows10 machine works.

Re: CIFS Mount Failed, Error 22

Is anyone able to apply the revert and build the cifs module for arch's linux? I tried just building the plain cifs module for 5.18.9 but I'm getting what look like linker errors in linux-stable:

$ git describe HEAD

Is our gcc too new or something?

Re: CIFS Mount Failed, Error 22

Try the other option and build with the  build headers for the installed/running kernel. This worked for me:

# https://downgit.github.io
# https://github.com/gregkh/linux/tree/v5.18.7/fs/cifs
# https://github.com/gregkh/linux/tree/v5.18.7/fs/smbfs_common
# directories: build/cifs, build/smbfs_common
# install linux-headers for your kernel
# https://docs.kernel.org/kbuild/modules.html

cd build/cifs
make -C /lib/modules/`uname -r`/build M=$PWD

Edit: In this case, building the version for v5.18.7 is the same as reverting the commits in 5.18.9.

Re: CIFS Mount Failed, Error 22

Thanks @Progandy, I did

$ git rev-list v5.18.7..v5.18.8 -- fs/cifs | xargs git revert
$ cd fs/cifs
$ make -j8 -C /lib/modules/`uname -r`/build M=$PWD
$ zstd cifs.ko
$ sudo cp cifs.ko.zst `modinfo -F filename cifs`

and it works now.

Re: CIFS Mount Failed, Error 22

Another workaround besides using gvfs-smb that also works, at least for me, is adding vers=2.0 to the options in /etc/fstab.

Re: CIFS Mount Failed, Error 22

I updated today my machine and after reboot my systemd CIFS mounts don't work anymore.
I see in journalctl that the error code is -22 " mount error(22): Invalid argument".
I changed nothing so I can only guess that something changed in CIFS and I need to adapt my mount units. But I don't know what the issue is.
This is my example unit. Actually in daily business it's started via an automount unit.
[Unit]
Description=media cifs mount
Requires=network-online.target
After=network-online.service

[Mount]
What=//myserver.mydomain.org/media
Where=/mnt/media
Type=cifs
Options=credentials=/home/user/.smb2credentials,vers=3.1.1,uid=1000,gid=1000

[Install]
WantedBy=multi-user.target

Does anybody see the issue?

Is there already an estimate when an fix can be expected?

Re: CIFS Mount Failed, Error 22

adding vers=2.0 to the options in /etc/fstab.

That's the best solution so far indeed.
vers=3.02 is working as well. vers=3.1.1 is broken.

Is anyone able to apply the revert and build the cifs module for arch's linux?

This might be a good speed/traffic (230MB) tradeoff:

git clone --depth=16 -b linux-5.18.y git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
cd linux
git revert -n 16d5d910 ca83f50b
cd fs/cifs
make -j4 -C /lib/modules/`uname -r`/build M=$PWD
strip -d cifs.ko
zstd cifs.ko
sudo cp cifs.ko.zst `modinfo -F filename cifs`

Re: CIFS Mount Failed, Error 22

Fortunately I already had a copy of linux-stable checked out. Progandy is right though it works just as well to build the 5.18.7 version with our 5.18.9 headers, which is faster than applying the reverts.

EDIT: If not, probably faster to grab the source tarball https://mirrors.edge.kernel.org/pub/lin … 8.7.tar.gz
