cifs: fix file info setting in cifs_open_file()

Browse source

commit ba5d4c1596 upstream.

In cifs_open_file(), @buf must hold a pointer to a cifs_open_info_data
structure which is passed by cifs_nt_open(), so assigning @buf
directly to @fi was obviously wrong.

Fix this by passing a valid FILE_ALL_INFO structure to SMBLegacyOpen()
and CIFS_open(), and then copy the set structure to the corresponding
cifs_open_info_data::fi field with move_cifs_info_to_smb2() helper.
