21 * Lustre wire protocol definitions.
23 * All structs passing over the wire should be declared here (lov_mds_md
24 * being the lone exception). Structs must be properly aligned to put
25 * 64-bit values on an 8-byte boundary. Any structs being added here
26 * must also be added to utils/wirecheck.c and "make newwiretest" run
27 * to regenerate the utils/wiretest.c sources. This allows us to verify
28 * that wire structs have the proper alignment/size on all architectures.
30 * We assume all nodes are either little-endian or big-endian, and we
31 * always send messages in the sender's native format. The receiver
32 * detects the message format by checking the 'magic' field of the message
33 * (see lustre_msg_swabbed() below).
35 * Each wire type has corresponding 'lustre_swab_xxxtypexxx()' routines,
36 * implemented either here, inline (trivial implementations) or in
37 * ptlrpc/pack_generic.c. These 'swabbers' convert the type from "other"
38 * endian, in-place in the message buffer.
40 * A swabber takes a single pointer argument. The caller must already have
41 * verified that the length of the message buffer >= sizeof (type).
43 * For variable length types, a second 'lustre_swab_v_xxxtypexxx()' routine
44 * may be defined that swabs just the variable part, after the caller has
45 * verified that the message buffer is large enough.
