42 | * | |
43 | * Lustre wire protocol definitions. | |
44 | * | |
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. | |
47 | * | |
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. | |
53 | * | |
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. | |
58 | * | |
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. | |
64 | * | |
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). | |
70 | * | |
71 | * We assume all nodes are either little-endian or big-endian, and we | |
72 | * always send messages in the sender's native format. The receiver | |
73 | * detects the message format by checking the 'magic' field of the message | |
74 | * (see lustre_msg_swabbed() below). | |
75 | * | |
76 | * Each wire type has corresponding 'lustre_swab_xxxtypexxx()' routines, | |
77 | * implemented either here, inline (trivial implementations) or in | |
78 | * ptlrpc/pack_generic.c. These 'swabbers' convert the type from "other" | |
79 | * endian, in-place in the message buffer. | |
80 | * | |
81 | * A swabber takes a single pointer argument. The caller must already have | |
82 | * verified that the length of the message buffer >= sizeof (type). | |
83 | * | |
84 | * For variable length types, a second 'lustre_swab_v_xxxtypexxx()' routine | |
85 | * may be defined that swabs just the variable part, after the caller has | |
86 | * verified that the message buffer is large enough. | |
87 | * | |
