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