4413c277ef s4-dsdb: Make dsdb_find_nc_root() first try and use DSDB_CONTROL_CURRENT_PARTITION_OID
This allows lookup of a DN with a GUID only or GUID and string,
possibly not yet in the database, yet still getting the correct result.

also crash in fruit_close() with 'debug level = 10' and vfs_default:VFS_OPEN_HOW_RESOLVE_NO_SYMLINKS = no

2d1f56c67e CVE-2022-37966 s4:kdc: announce PA-SUPPORTED-ETYPES like windows.
We need to take the value from the msDS-SupportedEncryptionTypes
attribute and only take the default if there's no value or
if the value is 0.

For krbtgt and DC accounts we need to force support for
ARCFOUR-HMAC-MD5 and AES encryption types and add the related bits
in addtition. (Note for krbtgt msDS-SupportedEncryptionTypes is
completely ignored the hardcoded value is the default, so there's
no AES256-SK for krbtgt).

For UF_USE_DES_KEY_ONLY on the account we reset
the value to 0, these accounts are in fact disabled completely,
as they always result in KRB5KDC_ERR_ETYPE_NOSUPP.

Then we try to get all encryption keys marked in
supported_enctypes, and the available_enctypes
is a reduced set depending on what keys are
actually stored in the database.

We select the supported session key enctypes by the available
keys and in addition based on AES256-SK as well as the
"kdc force enable rc4 weak session keys" option.

b615bf4333 lib/tsocket: avoid endless cpu-spinning in tstream_bsd_fde_handler()
There were some reports that strace output an LDAP server socket is in
CLOSE_WAIT state, returning EAGAIN for writev over and over (after a call to
epoll() each time).

In the tstream_bsd code the problem happens when we have a pending
writev_send, while there's no readv_send pending. In that case
we still ask for TEVENT_FD_READ in order to notice connection errors
early, so we try to call writev even if the socket doesn't report TEVENT_FD_WRITE.
And there are situations where we do that over and over again.

It happens like this with a Linux kernel:

    tcp_fin() has this:
        struct tcp_sock *tp = tcp_sk(sk);

        inet_csk_schedule_ack(sk);

        sk->sk_shutdown |= RCV_SHUTDOWN;
        sock_set_flag(sk, SOCK_DONE);

        switch (sk->sk_state) {
        case TCP_SYN_RECV:
        case TCP_ESTABLISHED:
                /* Move to CLOSE_WAIT */
                tcp_set_state(sk, TCP_CLOSE_WAIT);
                inet_csk_enter_pingpong_mode(sk);
                break;

It means RCV_SHUTDOWN gets set as well as TCP_CLOSE_WAIT, but
sk->sk_err is not changed to indicate an error.

    tcp_sendmsg_locked has this:
    ...
        err = -EPIPE;
        if (sk->sk_err || (sk->sk_shutdown & SEND_SHUTDOWN))
                goto do_error;

        while (msg_data_left(msg)) {
                int copy = 0;

                skb = tcp_write_queue_tail(sk);
                if (skb)
                        copy = size_goal - skb->len;

                if (copy <= 0 || !tcp_skb_can_collapse_to(skb)) {
                        bool first_skb;

    new_segment:
                        if (!sk_stream_memory_free(sk))
                                goto wait_for_space;

    ...

    wait_for_space:
                set_bit(SOCK_NOSPACE, &sk->sk_socket->flags);
                if (copied)
                        tcp_push(sk, flags & ~MSG_MORE, mss_now,
                                 TCP_NAGLE_PUSH, size_goal);

                err = sk_stream_wait_memory(sk, &timeo);
                if (err != 0)
                        goto do_error;

It means if (sk->sk_err || (sk->sk_shutdown & SEND_SHUTDOWN)) doesn't
hit as we only have RCV_SHUTDOWN and sk_stream_wait_memory returns
-EAGAIN.

    tcp_poll has this:

        if (sk->sk_shutdown & RCV_SHUTDOWN)
                mask |= EPOLLIN | EPOLLRDNORM | EPOLLRDHUP;

So we'll get EPOLLIN | EPOLLRDNORM | EPOLLRDHUP triggering
TEVENT_FD_READ and writev/sendmsg keeps getting EAGAIN.

So we need to always clear TEVENT_FD_READ if we don't
have readable handler in order to avoid burning cpu.
But we turn it on again after a timeout of 1 second
in order to monitor the error state of the connection.

And now that our tsocket_bsd_error() helper checks for POLLRDHUP,
we can check if the socket is in an error state before calling the
writable handler when TEVENT_FD_READ was reported.
Only on error we'll call the writable handler, which will pick
the error without calling writev().

We open a transaction when we have seen the hint that this user
has recorded a bad password.  This allows us to avoid always
needing one, while not missing a possible lockout.

We also go back and get a transation if we did not take out
one out but we chose to do a write (eg for lastLogonTimestamp)

71c94a076b smbXsrv_client: notify a different node to drop a connection by client guid.
If a client disconnected all its interfaces and reconnects when
the come back, it will likely start from any ip address returned
dns, which means it can try to connect to a different ctdb node.
The old node may not have noticed the disconnect and still holds
the client_guid based smbd.

Up unil now the new node returned NT_STATUS_NOT_SUPPORTED to
the SMB2 Negotiate request, as messaging_send_iov[_from]() will
return -1/ENOSYS if a file descriptor os passed to a process on
a different node.

Now we tell the other node to teardown all client connections
belonging to the client-guid.

Note that this is not authenticated, but if an attacker can
capture the client-guid, he can also inject TCP resets anyway,
to get the same effect.

Commit d71ef1365cdde47aeb3465699181656b0655fa04 caused a regression where the
creation date on streams wasn't updated anymore on the stream fsp.

By adding a simple wrapper vfs_fget_dos_attributes() that takes care of

- passing only the base_fsp to the VFS, so the VFS can be completely agnostic of
  all the streams related complexity like fake fds,

- propagating any updated btime from the base_fsp->fsp_name to the
  stream_fsp->fsp_name
