According to [MS-FSCC] if the file has the REPARSE_TAG attribute, the EaSize field must be interpreted as a reparse tag for these info levels: * FileFullDirectoryInfo * FileBothDirectoryInfo * FileIdFullDirectoryInfo * FileIdBothDirectoryInfo Otherwise we have code for querying the reparse tag in smb2_query_symlink(): rc = SMB2_ioctl_init(tcon, server, &rqst[1], fid.persistent_fid, fid.volatile_fid, FSCTL_GET_REPARSE_POINT, true /* is_fctl */, NULL, 0, CIFSMaxBufSize - MAX_SMB2_CREATE_RESPONSE_SIZE - MAX_SMB2_CLOSE_RESPONSE_SIZE); -- Aurélien Aptel / SUSE Labs Samba Team GPG: 1839 CB5F 9F5B FB9B AA97 8C99 03C8 A49B 521B D5D3 SUSE Software Solutions Germany GmbH, Maxfeldstr. 5, 90409 Nürnberg, DE GF: Felix Imendörffer, Mary Higgins, Sri Rasiah HRB 247165 (AG München)
