Smbd would disable "store dos attributes" on-the-fly if the attempt to set/get user.DOSATTRIB fails with ENOTSUP or ENOSYS. The rationale behind it was that the file system does not support extended attributes, so there's no need to fill up the log with failure messages. However, a "wide symlink" could point to a spot that doesn't support extended attributes. Even with the default banned wide links, we currenly allow stat'ing those files and follow the symlink, and this in turn would disable "store dos attributes" for the whole share. The user.DOSATTRIB attribute also stores file creation time, so that is also affected. Another case where this behavior would turn storage of DOS attributes off is that of the ".." entry at the root of the share, if the parent folder for the share's root path does not support extended attributes. On the other hand, the information on the file system and its support of extended attributes is readily available, so the fix for explosion of the log should be not to configure "store dos attributes" on such a share.
