Yeah
The scsi dissector does need some tlc
to clean up and to harmonize the dissection according to the latest
versions of the standard.
For handling flags,
you may want to look at some examples such as
...
static const int *aca_fields[] = {
&hf_scsi_inq_aerc, /* obsolete in spc3 and forward */
&hf_scsi_inq_trmtsk, /* obsolete in spc2 and forward */
&hf_scsi_inq_normaca,
&hf_scsi_inq_hisup,
&hf_scsi_inq_rdf,
NULL
};
...
/* aca flags */
proto_tree_add_bitmask(tree, tvb_v, offset_v,
hf_scsi_inq_acaflags, ett_scsi_inq_acaflags, aca_fields, FALSE);
offset_v+=1
which can simplify creating/dissecting bitfields.
this would be a reasonable summer of code project for a student,
go through all of spc/sbc/ssc/smc/mmc and update wireshark accordingly.
at the same time, and to have something to generate data to test with,
they could at the same time
enhance dbench.samba.org and its iscsi backend to be able to generate such i/o.
