Dear Dochelp:
In [MS-SMB2], sections 2.2.1.1 and 2.2.1.2 both describe the Command field
in the SMB2 header, and both give a complete list of all SMB2 commands.
Reading section 2.2.1, however, it seems that only the SMB2_CANCEL command
uses the ASYNC header format, and that all others use the SYNC format. If
that interpretation is correct, then...
* In section 2.2.1.1, only SMB2_CANCEL should be listed as a valid command
for the Command field.
* In section 2.2.1.2, SMB2_CANCEL should be excluded from the list of
valid SYNC-format requests.
* Section 2.2.30 should indicate that the ASYNC header should be used
instead of the SYNC header.
Am I misinterpreting the information in 2.2.1? Please clarify the
circumstances under which the ASYNC header format is used, vs. the SYNC format.
Thanks.
