Hello,
I am attempting to mount a CIFS share (SMB 1.0) onto an Ubuntu 14.04 client. I
would like to be able to map ACLs using the "cifsacl" mount option. The server
is an OpenIndiana server using the smb/server CIFS server (with ZFS as the
underlying filesystem).
Client Kernel Version: 3.13.0-24-generic
Client mount.cifs version: 6.0
I have verified that my kernel has been compiled with CIFS_XATTR and CIFS_ACL:
$ grep CIFS /boot/config-3.13.0-24-generic
CONFIG_CIFS=m
CONFIG_CIFS_STATS=y
# CONFIG_CIFS_STATS2 is not set
CONFIG_CIFS_WEAK_PW_HASH=y
CONFIG_CIFS_UPCALL=y
CONFIG_CIFS_XATTR=y
CONFIG_CIFS_POSIX=y
CONFIG_CIFS_ACL=y
CONFIG_CIFS_DEBUG=y
# CONFIG_CIFS_DEBUG2 is not set
CONFIG_CIFS_DFS_UPCALL=y
CONFIG_CIFS_SMB2=y
CONFIG_CIFS_FSCACHE=y
I have already configured winbind (getent passwd works and I verified that
cifs.idmap is set up in /etc/request-key.d/cifs.idmap.conf. I am able to mount
the share successfully, however when I attempt to list the contents of a
directory, I receive output like this:
ls: cannot access /mnt/Test/one: Input/output error
ls: cannot access /mnt/Test/two: Input/output error
ls: cannot access /mnt/Test/three: Input/output error
total 0
d????????? ? ? ? ? ? one
d????????? ? ? ? ? ? two
d????????? ? ? ? ? ? three
Here are the ACLs I have set on these directories:
A:d:OWNER@:rwaDdxtTnNcCoy
A:fi:OWNER@:rwaDdtTnNcCoy
A:dg:Domain Users@xxxxxxxx:rwaDdxtTnNcCoy
A:fig:Domain Users@xxxxxxxx:rwaDdtTnNcCoy
A:dg:GROUP@:rxtncy
A:fig:GROUP@:rtncy
D:d:EVERYONE@:rwaDxtTcCy
Errors in dmesg:
[Fri Nov 21 18:57:03 2014] CIFS VFS: cifs_acl_to_fattr: error -5 getting sec desc
[Fri Nov 21 18:57:03 2014] CIFS VFS: cifs_acl_to_fattr: error -13 getting sec desc
[Fri Nov 21 18:57:03 2014] CIFS VFS: cifs_acl_to_fattr: error -5 getting sec desc
I also grabbed the contents /f proc/fs/cifs/DebugData:
$ cat /proc/fs/cifs/DebugData

I then enabled /proc/fs/cifs/cifsFYI and captured this sample debug:

I see the error is NT_STATUS_NONE_MAPPED, but it is unclear why this is
failing. What else can I try to debug this CIFS mount?
Thanks,
Andrew Martin
