Windows 10 (1803 and higher) support and use
SMB_FILE_NORMALIZED_NAME_INFORMATION calls over the network. As a
fallback (in case the server don't support it) the client traverses all
path components, which is very expensive.
Implementing SMB_FILE_NORMALIZED_NAME_INFORMATION is very cheap for us
as the open already went through unix_convert() and we have the
information the client is asking for.

Sometimes Windows clients doesn't filter SECINFO_[UN]PROTECTED_[D|S]ACL flags
before sending the security_information to the server.
security_information = SECINFO_PROTECTED_DACL| SECINFO_DACL
results in a NULL dacl being returned from an GetSecurityDecriptor
request. This happens because posix_get_nt_acl_common()
has the following logic:
if ((security_info & SECINFO_DACL) && !(security_info & SECINFO_PROTECTED_DACL)) {
... create DACL ...
}
I'm not sure if the logic is correct or wrong in this place (I guess it's
wrong...).
But what I know is that the SMB server should filter the given
security_information flags before passing to the filesystem.
[MS-SMB2] 3.3.5.20.3 Handling SMB2_0_INFO_SECURITY
...
The server MUST ignore any flag value in the AdditionalInformation field that
is not specified in section 2.2.37.
Section 2.2.37 lists:
OWNER_SECURITY_INFORMATION
GROUP_SECURITY_INFORMATION
DACL_SECURITY_INFORMATION
SACL_SECURITY_INFORMATION
LABEL_SECURITY_INFORMATION
ATTRIBUTE_SECURITY_INFORMATION
SCOPE_SECURITY_INFORMATION
BACKUP_SECURITY_INFORMATION

Not all shares are a single volume. Some actually
expose multiple volumes under a single share. In these
cases showing the amount of space free as the space free

Do this by keeping a linked list of delete on close tokens, one for
each filename that identifies a path to the dev/inode. Use the
jenkins hash of the pathname to identify the correct token.
It turns out that the persistent handles are used by the Microsoft
redirector to index files on oplock break requests. So even if we
don't do durable handles (yet) we must set the persistent handle
on create. For now just use the same handle value as we use for
volatile.
