[cifs-protocol] [EXTERNAL] "Flags" field in [MS-SMB2] 2.2.2.2.1 Symbolic Link Error Response? - TrackingID#2211090040006372

[Sreekanth Nadendla]

Hello Volker,  what is the storage behind SMB server ? is it just a local disk ? Also do you see this error only on that 2016 server or you think it reproduces on other servers? E.g. Server 2019? Please share the build number of your 2016 server ( you may use winver to get that).

Regards,

Hi Dochelp,

[MS-SMB2] 2.2.2.2.1 describes the Flags field to have one of two
values: 0 (absolute symlink) and 1 (relative symlink).

Attached find a network trace of a test against Windows 2016 Standard. In frame 33 the test creates a symlink, and in frame 39 it tries to open it. Frame 40 correctly replies with NT_STATUS_STOPPED_ON_SYMLINK, but the "Flags" field has a value of 0x20000001. What is that additional bit?

Thanks,

Volker
