Hi, After a recent update of gentoo-sources from 5.18.7 to 5.18.10, i can't mount anymore CIFS share. mount -t cifs -o username=${s_user},noexec,nosuid,nodev,user,rw,uid=${s_uid},gid=${s_gid},rootcontext=staff_u:object_r:cifs_t,fscontext=staff_u:object_r:cifs_t" with, 5.18.7 : it works with 5.18.9 and 5.18.9 : it does not work anymore. > /var/log/kern.log CIFS: VFS: cifs_mount failed w/return code = -22 > emerge --info Portage 3.0.30 (python 3.10.5-final-0, default/linux/amd64/17.1/hardened/selinux, gcc-11.3.0,

-22 error looks like to be a generic error for CIFS that is not helpful... could you check the error logs on the server machine ? Can you try to bisect the kernel?
also attach the kernel configuration
Created attachment 791312 [details] kernel.config from the client
> could you check the error logs on the server machine ? File server is a FreeBSD, with Active Directory authentification. samba --version Version 4.7.0 /var/log/samba4 # tail -f log.smbd [2022/07/13 12:12:50.184573, 1] ../source3/smbd/service.c:521(make_connection_snum) create_connection_session_info failed: NT_STATUS_ACCESS_DENIED > Can you try to bisect the kernel? I do not understand.
can you try to use log level 10 on the smb server for looking better in detail why is failing the authentication. also did you recently update samba server ? what version of the samba server are you using?
sorry just now I looked your smb version. 4.7.x is really old and went EOL https://wiki.samba.org/index.php/Samba_Release_Planning that's probably why recent CIFS is no more supporting it.

This is a samba problem not kernel problem here is the fix tested on 4.12.x https://git.samba.org/?p=samba.git;a=commitdiff;h=147dd9d58a429695a3b6c6e45c8b0eaafc67908a
I have the same problem. Seems to be a bug on older Samba servers. But the client stopped working. The server version did not changed for me. I found a patch for the kernel: https://patchwork.kernel.org/project/cifs-client/patch/CAH2r5mtuN-yswT5VTbNPzj02fwiHYOCe2eR8mcgRgRE8Qpkjgw@mail.gmail.com/
Testing patch on gentoo-sources 5.18.11 https://gkernelci.gentoo.org/#/builders/71/builds/14
as I have no old samba server around for testing the patch other than building it can you confirm that the patch solve the issue ?
Yes, solved the issue. Tested with 5.8.11.
do you have any way of testing if works also with newer servers?
I can provide the versions I have tested.

My workaround, i used this version option : vers=2.1 instead of none.
@yesi the CIFS patch as been added in gentoo-sources 5.18.12 can you test it? thanks
@Alice Sorry for the delay, it worked without option "vers=2.1". Thanks.
