Subject: Re: [PATCH v4 05/24] smb: move some duplicate definitions to
common/smb1pdu.h
Greetings,
I couldn't find the definition of ATTR_VOLUME and ATTR_DEVICE in any of
the following documents:
- MS-FSCC:
https://learn.microsoft.com/pdf?url=https%3A%2F%2Flearn.microsoft.com%2Fen-us%2Fopenspecs%2Fwindows_protocols%2Fms-fscc%2Ftoc.json
- MS-CIFS:
https://learn.microsoft.com/pdf?url=https%3A%2F%2Flearn.microsoft.com%2Fen-us%2Fopenspecs%2Fwindows_protocols%2Fms-cifs%2Ftoc.json
- MS-SMB:
https://learn.microsoft.com/pdf?url=https%3A%2F%2Flearn.microsoft.com%2Fen-us%2Fopenspecs%2Fwindows_protocols%2Fms-smb%2Ftoc.json
- MS-SMB2:
https://learn.microsoft.com/pdf?url=https%3A%2F%2Flearn.microsoft.com%2Fen-us%2Fopenspecs%2Fwindows_protocols%2Fms-smb2%2Ftoc.json
- smb3-posix-spec: https://gitlab.com/samba-team/smb3-posix-spec
Are these two macro definitions (ATTR_VOLUME and ATTR_DEVICE) defined in
other documents?
PS: The following are the document locations I found for the File
Attribute flags:
/*
