Hi!

I upgraded the stock kernel on my slackware machine from 5.15.161 to 6.12.16 and I realized that I was not being able to create dot files in a cifs mounted volume. I just updated the kernel to 6.12.29 and I find the same behavior. The share is exported from a samba machine whose smb.conf file is the following (redacted for privacy) [global] security = ADS workgroup = ADDOMAIN realm = ADDOMAIN.COM username map = /etc/samba/user.map kerberos method = secrets and keytab winbind refresh tickets = Yes winbind expand groups = 2 winbind offline logon = Yes # winbind enum users = Yes # winbind enum groups = Yes dedicated keytab file = /etc/krb5.keytab idmap config * : backend = tdb idmap config * : range = 3000-7999 idmap config addomain:backend = ad idmap config addomain:schema_mode = rfc2307 idmap config addomain:range = 10000-999999 idmap config addomain:unix_nss_info = Yes vfs objects = acl_xattr map acl inherit = Yes store dos attributes = Yes printing = CUPS log level = 1 auth:3 auth_audit:3 auth_json_audit:3 rpc_server:spoolss = external rpc_daemon:spoolssd = fork spoolssd:prefork_min_children = 5 spoolssd:prefork_max_children = 25 spoolssd:prefork_spawn_rate = 5 spoolssd:prefork_max_allowed_clients = 100 spoolssd:prefork_child_min_life = 60 ntlm auth = mschapv2-and-ntlmv2-only

[printers] path = /var/spool/samba printable = Yes

[print$] path = /srv/samba/printer_drivers read only = No

[users] path = /home/users read only = No

[Publicas] path = /home/shares/publicas read only = No

The client is succesfully joined to the domain and the shares are mounted with the following parameters (redacted for privacy) //fileserver.addomain.com/Users/username on /home/username/.Documents type cifs (rw,relatime,vers=3.1.1,cache=strict,username=username,domain=ADDOMAIN,uid=11002,forceuid,gid=10513,forcegid,addr=192.168.25.6,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,reparse=nfs,rsize=4194304,wsize=4194304,bsize=1048576,retrans=1,echo_interval=60,actimeo=1,closetimeo=1) //fileserver.addomain.com/Publicas on /home/username/Public type cifs (rw,relatime,vers=3.1.1,cache=strict,username=username,domain=ADDOMAIN,uid=11002,forceuid,gid=10513,forcegid,addr=192.168.25.6,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,reparse=nfs,rsize=4194304,wsize=4194304,bsize=1048576,retrans=1,echo_interval=60,actimeo=1,closetimeo=1)

If I issue the following command cd /home/username/.Documents/ touch .foo.bar (this file doesn't exist on the volume) I get the following error "touch: cannot touch '.foo.bar': Permission denied" When I increase the debug by issuing the following command all echo 7 > /proc/fs/cifs/cifsFYI

All I get in dmesg is [ 2702.654271] CIFS: Status code returned 0xc0000034 STATUS_OBJECT_NAME_NOT_FOUND

However the even weirder part is that on the "Publicas" volume I have no such issue cd /home/username/Public/ touch ./.foo.bar ls -alt -rwxr-xr-x 1 ADDOMAIN\username ADDOMAIN\domain users 0 may 21 14:57 .foo.bar

If I boot back 5.15.161 I have no such problem.

Thanks in advance! Best regards, Dave.
