Re: [Samba] Operation Not Supported error for GETXATTR when VFS plugin "nfs4acl_xattr" is used




Hi All

I found there is one bug in the plugin. The name of the attribute for ACL
as per strace output of nfs4_setfacl is *system.nfs4_acl.*
The source code has defined it as
#define NFS4ACL_XATTR_NAME      ( "system.nfs4acl" )

Note there is missing underscore.

After this, the EOPNOTSUPP error is not observed.

Hope this helps
