s4:kdc: fix user2user tgs-requests for normal user accounts

User2User tgs requests use the session key of the additional
ticket instead of the long term keys based on the password.

In addition User2User also asserts that client and server
are the same account (cecked based on the sid).

TODO lorikeet-first HEIMDAL:kdc: introduce HDB_F_USER2USER_PRINCIPAL

This allows HDB backends to do special handling for
User2User TGS-REQs. The main reason is to let
the HDB_F_GET_SERVER lookup to succeed even for
non-computer accounts. In Samba these are typically
not returned in HDB_F_GET_SERVER in order to avoid
generating tickets with the user password.

But for User2User the account password is not used,
so it is safe to return the server entry.

Otherwise it's possible to get a different behavior

This allows KRB5_VERIFY_AP_REQ_SKIP_TRANSITED_CHECK (on the acceptor)

Members of Active Directory domains should just rely on there
KDCs (domain controllers) to do SID-Filtering (and name checking)
on trust boundaries, I have verified this with a modified Samba KDC
and a Windows 2012R2 DC. The Windows DC rejects invalid cross-realm tickets
with KRB5KDC_ERR_POLICY, before generating a new (service or referral)
ticket. So any service ticket is already policy checked by the KDC
even if this does not result in setting the transited_policy_checked in the ticket.

This means an accepting service can tell gss_accept_sec_context()
to skip any transited checking, as the trust topoligy is only
fully known to the KDC anyway.

s3: smbd: Ignore fstat() error on deleted stream in fd_close().

In the fd_close() fsp->fsp_flags.fstat_before_close code path.

If this is a stream and delete-on-close was set, the
backing object (an xattr from streams_xattr) might
already be deleted so fstat() fails with
NT_STATUS_NOT_FOUND. So if fsp refers to a stream we
ignore the error and only bail for normal files where
an fstat() should still work. NB. We cannot use
fsp_is_alternate_stream(fsp) for this as the base_fsp
has already been closed at this point and so the value
fsp_is_alternate_stream() checks for is already NULL.

Remove knownfail.

ctdb-daemon: Call setproctitle_init()

Commit 19c82c19c009eefe975ae95c8b709fc93f5f4c39 changed the behaviour
of prctl_set_comment() so it now calls setproctitle(3bsd) by default.

In some Linux distributions (e.g. Rocky Linux 8.8), this results in
messages like this spamming the logs:

  ctdbd: setproctitle not initialized, please either call setproctitle_init() or link against libbsd-ctor.

Most Samba daemons seem to call setproctitle_init(), so do it here.

In the longer term CTDB should also switch to using lib/util's
process_set_title(), like the rest of Samba, for more flexible process
names.

CVE-2023-42670 s3-rpc_server: Remove cross-check with "samba" EPM lookup

We now have ensured that no conflicting services attempt to start
so we do not need the runtime lookup and so avoid the risk that
the lookup may fail.

This means that any duplicates will be noticed early not just
in a race condition.
