33 * This file is part of Lustre, http://www.lustre.org/
34 * Lustre is a trademark of Sun Microsystems, Inc.
36 * lustre/include/lustre/lustre_idl.h
38 * Lustre wire protocol definitions.
41 * We assume all nodes are either little-endian or big-endian, and we
42 * always send messages in the sender's native format. The receiver
43 * detects the message format by checking the 'magic' field of the message
44 * (see lustre_msg_swabbed() below).
45 * ALL structs passing over the wire should be declared here. Structs
46 * that are used in interfaces with userspace should go in lustre_user.h.
48 * All structs being declared here should be built from simple fixed-size
49 * types (__u8, __u16, __u32, __u64) or be built from other types or
50 * structs also declared in this file. Similarly, all flags and magic
51 * values in those structs should also be declared here. This ensures
52 * that the Lustre wire protocol is not influenced by external dependencies.
54 * The only other acceptable items in this file are VERY SIMPLE accessor
55 * functions to avoid callers grubbing inside the structures, and the
56 * prototypes of the swabber functions for each struct. Nothing that
57 * depends on external functions or definitions should be in here.
59 * Structs must be properly aligned to put 64-bit values on an 8-byte
60 * boundary. Any structs being added here must also be added to
61 * utils/wirecheck.c and "make newwiretest" run to regenerate the
62 * utils/wiretest.c sources. This allows us to verify that wire structs
63 * have the proper alignment/size on all architectures.
65 * DO NOT CHANGE any of the structs, flags, values declared here and used
66 * in released Lustre versions. Some structs may have padding fields that
67 * can be used. Some structs might allow addition at the end (verify this
68 * in the code to ensure that new/old clients that see this larger struct
69 * do not fail, otherwise you need to implement protocol compatibility).
71 * Each wire type has corresponding 'lustre_swab_xxxtypexxx()' routines,
72 * implemented either here, inline (trivial implementations) or in
73 * ptlrpc/pack_generic.c. These 'swabbers' convert the type from "other"
74 * endian, in-place in the message buffer.
76 * A swabber takes a single pointer argument. The caller must already have
77 * verified that the length of the message buffer >= sizeof (type).
79 * For variable length types, a second 'lustre_swab_v_xxxtypexxx()' routine
80 * may be defined that swabs just the variable part, after the caller has
81 * verified that the message buffer is large enough.
