Subject: CAR - missing SMB2 SetFileInfo levels


MS-SMB2 section 2.2.39 says that these are the only 12 levels for

 FileBasicInformation            4
 FileRenameInformation          10
 FileLinkInformation            11
 FileDispositionInformation     13
 FilePositionInformation        14
 FileFullEaInformation          15
 FileModeInformation            16
 FileAllocationInformation      19
 FileEndOfFileInformation       20
 FilePipeInformation            23
 FileValidDataLengthInformatio  39
 FileShortNameInformation       40

Section says that any unsupported level must respond with

A scanner in our testsuite (the SMB2-SCANSETINFO test) shows that
Vista responds to an additional 11 levels with some other error code,
indicating that the level is available.

The additional levels are

  25, 27, 29, 30, 31, 32, 36, 41, 42, 43, 44

Can you please document these additional levels?

The scan also shows that Vista responds to 4 setfsinfo levels:

 2, 6, 8, 10

but the doc only lists 6 and 8. Can you please document the extra 2

Cheers, Tridge
