Subject: [MS-SMB2:2.2.1.x] SYNC vs. ASYNC commands.
In [MS-SMB2], sections 220.127.116.11 and 18.104.22.168 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 22.214.171.124, only SMB2_CANCEL should be listed as a valid command
for the Command field.
* In section 126.96.36.199, 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.
