Bug#877764: linux-image-amd64: cifs mount gets automatically the file_mode=0755,dir_mode=0755 options
hi, when sid pulled the 4.13 kernel, i noticed that these mounts automatically get the file_mode=0755 and dir_mode=0755 options. It appears that this indicates the server does not support Unix extensions. What is the file server running? it's the debian sid's samba daemon: Version 4.6.7-Debian And the 'nounix' confirms that. ohhh, i did not noticed this. anyway i've looked at smbd config and i contains the line unix extensions = yes. Are there any messages in the kernel log relating to cifs? nothing interesting.

Bug#877764: linux-image-amd64: cifs mount gets automatically the file_mode=0755,dir_mode=0755 options
Package: linux-image-amd64
Version: 4.13+86
Severity: normal
Dear Maintainer,
i'm mounting my shares through cifs for years.
when sid pulled the 4.13 kernel, i noticed that these mounts
automatically get the file_mode=0755 and dir_mode=0755 options.
the fstab looks like this:
//nas.mchome.nop.hu/mc36 /nfs cifs
user=mc36,password=***,uid=mc36,gid=mc36 0 0
then the resulting mount looks like this:
//nas.mchome.nop.hu/mc36 on /nfs type cifs
(rw,relatime,vers=3.0,cache=strict,username=mc36,domain=,uid=1000,forceuid,gid=1000,forcegid,addr=2001:0db8:1001:0255:0200:4eff:fe36:4e35,file_mode=0755,dir_mode=0755,nounix,serverino,mapposix,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1,user=mc36)
things look similarly if i add vers=2.0 to the fstab. only vers=1.0
solves the issue.
