cifs: Fix struct FILE_ALL_INFO
struct FILE_ALL_INFO for level 263 (0x107) used by QPathInfo does not have any IndexNumber, AccessFlags, IndexNumber1, CurrentByteOffset, Mode or AlignmentRequirement members. So remove all of them. Also adjust code in move_cifs_info_to_smb2() function which converts struct FILE_ALL_INFO to struct smb2_file_all_info. Fixed content of struct FILE_ALL_INFO was verified that is correct against: * [MS-CIFS] section 2.2.8.3.10 SMB_QUERY_FILE_ALL_INFO * Samba server implementation of trans2 query file/path for level 263 * Packet structure tests against Windows SMB servers This change fixes CIFSSMBQFileInfo() and CIFSSMBQPathInfo() functions which directly copy received FILE_ALL_INFO network buffers into kernel structures of FILE_ALL_INFO type. struct FILE_ALL_INFO is the response structure returned by the SMB server. So the incorrect definition of this structure can lead to returning bogus information in stat() call. Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
