/** \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.
