From Javier Godoy via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8905 SCSI OSD: per-attribute subtree
The response of the OSD-2 LIST command may contain attributes in multi-object retrieved attributes format. Currently all proto_items for that attributes are put under the SCSI Payload tree, yielding a large list of items:
Partition Id
Object Type
Attribute Page
Attribute Number
Attribute Length
(optional attribute-specific fields)
Attribute Page, ...
Partition Id
Object Type
Attribute Page, ...
...
This patch classifies the OSD-2 LIST attributes (from the Data In buffer) in one tree per object and one sub-tree per attribute
Partition Id (ett_osd_multi_object tree)
Object Type
Attribute (ett_osd_attribute tree)
Attribute Page
Attribute Number
Attribute Length
(optional attribute-specific fields)
Attribute, ...
Partition Id
Object Type
Attribute Page, ...
...
The same approach is applied to attributes in the Get/Set attributes segments.
A function *attribute_page_numbers_t lookup_osd_attribute(page,number) was created, with common code that is called from dissect_osd_attributes_list, dissect_osd_attribute_value and dissect_osd2_attribute_list_entry.
The trees are built in function dissect_osd_attribute_list_entry. That function was modified for avoiding code duplication with case 0x09 of dissect_osd_attributes_list. A missing padding was added in the process.
The function dissect_osd_partition_id now returns proto_item*, so that we can create a subtree rooted at the partition_id (previously it returned an offset, but the return value was unused).
From me:
