| /** \defgroup lustreidl lustreidl |
| * |
| * Lustre wire protocol definitions. |
| * |
| * ALL structs passing over the wire should be declared here. 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. |
