2018-10-23cifs: add IOCTL for QUERY_INFO passthrough to userspaceRonnie Sahlberg
This allows userspace tools to query the raw info levels for cifs files and process the response in userspace. In particular this is useful for many of those data where there is no corresponding native data structure in linux. For example querying the security descriptor for a file and extract the SIDs.

2015-08-20Add way to query server fs info for smb3Steve French
The server exports information about the share and underlying device under an SMB3 export, including its attributes and capabilities, which is stored by cifs.ko when first connecting to the share. Add ioctl to cifs.ko to allow user space smb3 helper utilities (in cifs-utils) to display this (e.g. via smb3util). This information is also useful for debugging and for resolving configuration errors. Signed-off-by: Steve French <steve.french@primarydata.com>
