Subject: CAR - missing SMB2 GetFileInfo levels
Hi,
MS-SMB2 section 2.2.37 says that these are the only 19 levels for
getfileinfo:
FileBasicInformation
FileStandardInformation
FileInternalInformation
FileEaInformation
FileAccessInformation
FilePositionInformation
FileFullEaInformation
FileModeInformation
FileAlignmentInformation
FileAllInformation
FileAlternateNameInformation
FileStreamInformation
FilePipeInformation
FilePipeLocalInformation
FilePipeRemoteInformation
FileCompressionInformation
FileQuotaInformation
FileNetworkOpenInformation
FileAttributeTagInformation
Section 3.3.5.20.1 says that any unsupported level must respond with
STATUS_INVALID_INFO_CLASS
A scanner in our testsuite (the SMB2-SCANGETINFO test) shows that
Vista responds to a total of 31 levels with some other error code,
indicating that the level is available.
The levels our scanner finds are:
4, 5, 6, 7, 8, 9, 14, 15, 16, 17, 18, 21, 22, 23, 24, 25, 26, 28, 29,
32, 33, 34, 35, 41, 43, 44, 45, 46, 47, 48, 49
Can you please document the missing levels?
The scan also shows that Vista responds to 9 getfsinfo levels:
1, 3, 4, 5, 6, 7, 8, 9, 10
but the doc only lists 6 levels. Can you please document the extra 3
levels?
Cheers, Tridge
