Windows treats Kerberos strings as UTF‐8, but by default, pyasn1 encodes
strings as ISO-8859-1. (There is a UTF8String type that gets encoded as
UTF‐8, but it has a different ASN.1 encoding from GeneralString, and so
can’t be used). asn1ate provides no way to override the encoding.
Except…
It turns out we can force UTF‐8 encoding by cunningly overriding
KerberosString.__getattribute__().

‘rfc4120_pyasn1_generated’ is not to be used directly. Its contents are
now reexported from ‘rfc4120_pyasn1’, which becomes a simple wrapper.

Use O_PATH when available; this avoids the need for READ/LIST access on
that directory. Keep using O_RDONLY if the system does not have O_PATH.

There is no claim called ‘abc’, so the condition ‘(abc)’ is always going
to fail. Replace this with a condition using ‘Member_of’.
Furthermore, an ACL containing only Deny ACEs will only ever deny. Add a
trailing Allow ACE so that the ACL might allow other principals.

This is more lines of code, but it's still a simplification. With this
patch we don't call the full openat_pathref_fsp() anymore when looking
up the last component in filename_convert_dirfsp(), instead we do the
direct SMB_VFS_OPENAT(). We don't need the whole complexity of
non_widelink_open() for this case, we do know that we have a real
non-cwd dirfsp.
The other big change that is not obvious just from looking at the
patch: This removes the special case for looking up posix
symlinks. Before this patch, filename_convert_dirfsp() returned a
proper smb_filename but without an attached fsp when a smb1 posix
client hits a symlink. This caused all sorts of special case code
everywhere. For example smbd_do_qfilepathinfo() needs to cover both
cases just for the smb1 posix symlink case. This special-case handling
can go now. We can do the path lookup in the smb1-only qpathinfo code
and call into the common code with a proper fsp.
When hitting a symlink and with O_PATH available, we'll get the
symlink opened with an O_PATH fd. Without O_PATH we obviously can't do
that, there we get fd=-1 and an indication that we don't have the
procfd fallback around.
Why all this?
I want to present FIFOs (and eventually symlinks) as reparse points as
the very next step. Without this patch, there is no real unified way
to get the file attributes from disk. Now we can use the proper logic
of fdos_mode() everywhere and not rely on special cases for fsp==NULL.
This patch also changes some error codes for smb1 posix extensions. I
chose to just change the test instead of going after each and every
change. As long as we do get an error, I'm willing to accept that we
slightly change error path behaviour for this deprecated code.
And, I tried to split this up into smaller patches but I failed.

filename_convert_dirfsp() is the only caller of
safe_symlink_target_path(). Right now this is not called with
"unparsed==0" because the last component is handled in
openat_pathref_fsp() and thus non_widelink_open(). I have code that
will change this, so that we can simplify
openat_pathref_fsp_case_insensitive() to directly call OPENAT, not
going through non_widelink_open. This will cause
safe_symlink_target_path() also be called for the last component,
which means it needs logic to distinguish between PATH_ and
NAME_NOT_FOUND.
