Some of the most difficult to debug issues in Samba development are around
timing, so this changes our default logging format in the selftest system
to include a high-resolution timestamp to help correlate bad events with
what else is going on at the same time.
This fits in well with the timestamps already logged into st/subunit
and may assist with correlation.

This one is tricky. It sends SMB2 DFS pathnames to a non-DFS
share, and sets the SMB2 flag FLAGS2_DFS_PATHNAMES in the SMB2
packet.
Windows will have non of it and (correctly) treats the pathnames
as local paths (they're going to a non-DFS share). Samba fails.
This proves the server looks as the share DFS capability to
override the flag in the SMB2 packet.
Passes against Windows. Added knownfail for Samba.

Passes fully against Windows.
This shows that DFS paths on Windows on SMB2 must
be of the form:
SERVER\SHARE\PATH
but the actual contents of the strings SERVER and
SHARE don't need to match the given server or share.
The algorithm the Windows server uses is the following:
Look for a '\\' character, and assign anything before
that to the SERVER component. The characters in this
component are not checked for validity.
Look for a second '\\' character and assign anything
between the first and second '\\' characters to the
SHARE component. The characters in the share component
are checked for validity, but only ':' is flagged as
an illegal sharename character despite what:
[MS-FSCC] https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-fscc/dc9978d7-6299-4c5a-a22d-a039cdc716ea
says.
Anything after the second '\\' character is assigned
to the PATH component and becomes the share-relative
path.
If there aren't two '\\' characters it removes
everything and ends up with the empty string as
the share relative path.
To give some examples, the following pathnames all map
to the directory at the root of the DFS share:
SERVER\SHARE
SERVER
""
ANY\NAME
ANY
::::\NAME
the name:
SERVER\:
is illegal (sharename contains ':') and the name:
ANY\NAME\file
maps to a share-relative pathname of "file",
despite "ANY" not being the server name, and
"NAME" not being the DFS share name we are
connected to.
Adds a knownfail for smbd as our current code
in parse_dfs_path() is completely incorrect
here and tries to map "incorrect" DFS names
into local paths. I will work on fixing this
later, but we should be able to remove parse_dfs_path()
entirely and move the DFS pathname logic before
the call to filename_convert_dirfsp() in the
same way Volker suggested and was able to achieve
for extract_snapshot_token() and the @GMT pathname
processing.
Also proves the "target" paths for SMB2_SETINFO
rename and hardlink must *not* be DFS-paths.
Next I will work on a torture tester for SMB1
DFS paths.

When using vfs_streams_xattr, for a pathref handle of a stream the system fd
will be a fake fd created by pipe() in vfs_fake_fd().
For the following callchain we wrongly pass a stream fsp to
SMB_VFS_FGET_NT_ACL():
SMB_VFS_CREATE_FILE(..., "file:stream", ...)
=> open_file():
if (open_fd):
-> taking the else branch:
-> smbd_check_access_rights_fsp(stream_fsp)
-> SMB_VFS_FGET_NT_ACL(stream_fsp)
This is obviously wrong and can lead to strange permission errors when using
vfs_acl_xattr:
in vfs_acl_xattr we will try to read the stored ACL by calling
fgetxattr(fake-fd) which of course faild with EBADF. Now unfortunately the
vfs_acl_xattr code ignores the specific error and handles this as if there was
no ACL stored and subsequently runs the code to synthesize a default ACL
according to the setting of "acl:default acl style".
As the correct access check for streams has already been carried out by calling
check_base_file_access() from create_file_unixpath(), the above problem is not
a security issue: it can only lead to "decreased" permissions resulting in
unexpected ACCESS_DENIED errors.
The fix is obviously going to be calling
smbd_check_access_rights_fsp(stream_fsp->base_fsp).
This test verifies that deleting a file works when the stored NT ACL grants
DELETE_FILE while the basic POSIX permissions (used in the acl_xattr fallback
code) do not.

This still applies to testing the build with system krb5 libraries
but without relying on a running ad dc.
As a domain member setup requires a running winbindd, we should test it
that way, in order to reflect a valid setup.
As a side effect it provides a way to demonstrate that we can accept
smb connections authenticated via kerberos, but no connection to
a domain controller! In order get this working offline, we need an
