Structs - * that are used in interfaces with userspace should go in lustre_user.h. - * - * All structs being declared here should be built from simple fixed-size - * types (__u8, __u16, __u32, __u64) or be built from other types or - * structs also declared in this file. Similarly, all flags and magic - * values in those structs should also be declared here. This ensures - * that the Lustre wire protocol is not influenced by external dependencies. - * - * The only other acceptable items in this file are VERY SIMPLE accessor - * functions to avoid callers grubbing inside the structures. Nothing that - * depends on external functions or definitions should be in here. - * - * Structs must be properly aligned to put 64-bit values on an 8-byte - * boundary. Any structs being added here must also be added to - * utils/wirecheck.c and "make newwiretest" run to regenerate the - * utils/wiretest.c sources. This allows us to verify that wire structs - * have the proper alignment/size on all architectures. - * - * DO NOT CHANGE any of the structs, flags, values declared here and used - * in released Lustre versions. Some structs may have padding fields that - * can be used. Some structs might allow addition at the end (verify this - * in the code to ensure that new/old clients that see this larger struct - * do not fail, otherwise you need to implement protocol compatibility). - * - * @{ - */ - -#ifndef _LUSTRE_IDL_H_ -#define _LUSTRE_IDL_H_ - -#include <asm/byteorder.h> -#include <linux/types.h> - -#include <uapi/linux/lnet/lnet-types.h> -/* Defn's shared with user-space. */ -#include <uapi/linux/lustre/lustre_user.h> -#include <uapi/linux/lustre/lustre_ver.h> - -/* - * GENERAL STUFF - */ -/* FOO_REQUEST_PORTAL is for incoming requests on the FOO - * FOO_REPLY_PORTAL is for incoming replies on the FOO - * FOO_BULK_PORTAL is for incoming bulk on the FOO - */ - -/* Lustre service names are following the format - * service name + MDT + seq name - */ -#define LUSTRE_MDT_MAXNAMELEN 80 - -#define CONNMGR_REQUEST_PORTAL 1 -#define CONNMGR_REPLY_PORTAL 2 -/*#define OSC_REQUEST_PORTAL 3 */ -#define OSC_REPLY_PORTAL 4 -/*#define OSC_BULK_PORTAL 5 */ -#define OST_IO_PORTAL 6 -#define OST_CREATE_PORTAL 7 -#define OST_BULK_PORTAL 8 -/*#define MDC_REQUEST_PORTAL 9 */ -#define MDC_REPLY_PORTAL 10 -/*#define MDC_BULK_PORTAL 11 */ -#define MDS_REQUEST_PORTAL 12 -/*#define MDS_REPLY_PORTAL 13 */ -#define MDS_BULK_PORTAL 14 -#define LDLM_CB_REQUEST_PORTAL 15 -#define LDLM_CB_REPLY_PORTAL 16 -#define LDLM_CANCEL_REQUEST_PORTAL 17 -#define LDLM_CANCEL_REPLY_PORTAL 18 -/*#define PTLBD_REQUEST_PORTAL 19 */ -/*#define PTLBD_REPLY_PORTAL 20 */ -/*#define PTLBD_BULK_PORTAL 21 */ -#define MDS_SETATTR_PORTAL 22 -#define MDS_READPAGE_PORTAL 23 -#define OUT_PORTAL 24 - -#define MGC_REPLY_PORTAL 25 -#define MGS_REQUEST_PORTAL 26 -#define MGS_REPLY_PORTAL 27 -#define OST_REQUEST_PORTAL 28 -#define FLD_REQUEST_PORTAL 29 -#define SEQ_METADATA_PORTAL 30 -#define SEQ_DATA_PORTAL 31 -#define SEQ_CONTROLLER_PORTAL 32 -#define MGS_BULK_PORTAL 33 - -/* Portal 63 is reserved for the Cray Inc DVS - nic@cray.com, roe@cray.com, - * n8851@cray.com - */ - -/* packet types */ -#define PTL_RPC_MSG_REQUEST 4711 -#define PTL_RPC_MSG_ERR 4712 -#define PTL_RPC_MSG_REPLY 4713 - -/* DON'T use swabbed values of MAGIC as magic! */ -#define LUSTRE_MSG_MAGIC_V2 0x0BD00BD3 -#define LUSTRE_MSG_MAGIC_V2_SWABBED 0xD30BD00B - -#define LUSTRE_MSG_MAGIC LUSTRE_MSG_MAGIC_V2 - -#define PTLRPC_MSG_VERSION 0x00000003 -#define LUSTRE_VERSION_MASK 0xffff0000 -#define LUSTRE_OBD_VERSION 0x00010000 -#define LUSTRE_MDS_VERSION 0x00020000 -#define LUSTRE_OST_VERSION 0x00030000 -#define LUSTRE_DLM_VERSION 0x00040000 -#define LUSTRE_LOG_VERSION 0x00050000 -#define LUSTRE_MGS_VERSION 0x00060000 - -/** - * Describes a range of sequence, lsr_start is included but lsr_end is - * not in the range. - * Same structure is used in fld module where lsr_index field holds mdt id - * of the home mdt. - */ -struct lu_seq_range { - __u64 lsr_start;
