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, and the * prototypes of the swabber functions for each struct. 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). * * We assume all nodes are either little-endian or big-endian, and we * always send messages in the sender's native format. The receiver * detects the message format by checking the 'magic' field of the message * (see lustre_msg_swabbed() below). * * Each wire type has corresponding 'lustre_swab_xxxtypexxx()' routines, * implemented either here, inline (trivial implementations) or in * ptlrpc/pack_generic.c. These 'swabbers' convert the type from "other" * endian, in-place in the message buffer. * * A swabber takes a single pointer argument. The caller must already have * verified that the length of the message buffer >= sizeof (type). * * For variable length types, a second 'lustre_swab_v_xxxtypexxx()' routine * may be defined that swabs just the variable part, after the caller has * verified that the message buffer is large enough. * * @{ */ #ifndef _LUSTRE_IDL_H_ #define _LUSTRE_IDL_H_ #include /* Defn's shared with user-space. */ #include #include /* * 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 */ #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 MDS_MDS_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 SVC_KILLED 1 #define SVC_EVENT 2 #define SVC_SIGNAL 4 #define SVC_RUNNING 8 #define SVC_STOPPING 16 #define SVC_STOPPED 32 /* 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_V1 0x0BD00BD0 #define LUSTRE_MSG_MAGIC_V2 0x0BD00BD3 #define LUSTRE_MSG_MAGIC_V1_SWABBED 0xD00BD00B #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 typedef __u32 mdsno_t; typedef __u64 seqno_t; /** * 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_mdt field holds mdt id * of the home mdt. */ struct lu_seq_range { __u64 lsr_start; __u64 lsr_end; __u32 lsr_mdt; __u32 lsr_padding; }; /** * returns width of given range \a r */ static inline __u64 range_space(const struct lu_seq_range *range) { return range->lsr_end - range->lsr_start; } /** * initialize range to zero */ static inline void range_init(struct lu_seq_range *range) { range->lsr_start = range->lsr_end = range->lsr_mdt = 0; } /** * check if given seq id \a s is within given range \a r */ static inline int range_within(const struct lu_seq_range *range, __u64 s) { return s >= range->lsr_start && s < range->lsr_end; } /** * allocate \a w units of sequence from range \a from. */ static inline void range_alloc(struct lu_seq_range *to, struct lu_seq_range *from, __u64 width) { to->lsr_start = from->lsr_start; to->lsr_end = from->lsr_start + width; from->lsr_start += width; } static inline int range_is_sane(const struct lu_seq_range *range) { return (range->lsr_end >= range->lsr_start); } static inline int range_is_zero(const struct lu_seq_range *range) { return (range->lsr_start == 0 && range->lsr_end == 0); } static inline int range_is_exhausted(const struct lu_seq_range *range) { return range_space(range) == 0; } #define DRANGE "[%#16.16"LPF64"x-%#16.16"LPF64"x):%x" #define PRANGE(range) \ (range)->lsr_start, \ (range)->lsr_end, \ (range)->lsr_mdt /** \defgroup lu_fid lu_fid * @{ */ /** * Flags for lustre_mdt_attrs::lma_compat and lustre_mdt_attrs::lma_incompat. */ enum lma_compat { LMAC_HSM = 0x00000001, LMAC_SOM = 0x00000002, }; /** * Masks for all features that should be supported by a Lustre version to * access a specific file. * This information is stored in lustre_mdt_attrs::lma_incompat. * * NOTE: No incompat feature should be added before bug #17670 is landed. */ #define LMA_INCOMPAT_SUPP 0x0 /** * Following struct for MDT attributes, that will be kept inode's EA. * Introduced in 2.0 release (please see b15993, for details) */ struct lustre_mdt_attrs { /** * Bitfield for supported data in this structure.
