CVE-2022-38023 docs-xml/smbdotconf: change 'reject md5 clients' default to yes
AES is supported by Windows Server >= 2008R2, Windows (Client) >= 7 and Samba >= 4.0,
so there's no reason to allow md5 clients by default.
However some third party domain members may need it.

CVE-2022-44640 HEIMDAL: asn1: invalid free in ASN.1 codec
Heimdal's ASN.1 compiler generates code that allows specially
crafted DER encodings of CHOICEs to invoke the wrong free function
on the decoded structure upon decode error. This is known to impact
the Heimdal KDC, leading to an invalid free() of an address partly
or wholly under the control of the attacker, in turn leading to a
potential remote code execution (RCE) vulnerability.
This error affects the DER codec for all CHOICE types used in
Heimdal, though not all cases will be exploitable. We have not
completed a thorough analysis of all the Heimdal components
affected, thus the Kerberos client, the X.509 library, and other
parts, may be affected as well.
This bug has been in Heimdal since 2005. It was first reported by
Douglas Bagnall, though it had been found independently by the
Heimdal maintainers via fuzzing a few weeks earlier.

third_party/heimdal: Introduce macro for common plugin structure elements
Heimdal's HDB plugin interface, and hence Samba's KDC that depends upon
it, doesn't work on 32-bit builds due to structure fields being arranged
in the wrong order. This problem presents itself in the form of
segmentation faults on 32-bit systems, but goes unnoticed on 64-bit
builds thanks to extra structure padding absorbing the errant fields.
This commit reorders the HDB plugin structure fields to prevent crashes
and introduces a common macro to ensure every plugin presents a
consistent interface.

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);
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().

CVE-2022-3437 third_party/heimdal: Avoid undefined behaviour in _gssapi_verify_pad()
By decrementing 'pad' only when we know it's safe, we ensure we can't
stray backwards past the start of a buffer, which would be undefined
behaviour.
In the previous version of the loop, 'i' is the number of bytes left to
check, and 'pad' is the current byte we're checking. 'pad' was
decremented at the end of each loop iteration. If 'i' was 1 (so we
checked the final byte), 'pad' could potentially be pointing to the
first byte of the input buffer, and the decrement would put it one
byte behind the buffer.
That would be undefined behaviour.
The patch changes it so that 'pad' is the byte we previously checked,
which allows us to ensure that we only decrement it when we know we
have a byte to check.
As described by the C standard, __func__ is a variable, not a macro.
Hence this #ifndef check does not work as intended, and only serves to
unconditionally disable __func__. A nonoperating __func__ prevents
cmocka operating correctly, so remove this definition.

smbXsrv_client: handle NAME_NOT_FOUND from smb2srv_client_connection_{pass,drop}()
If we get NT_STATUS_OBJECT_NOT_FOUND from smb2srv_client_connection_{pass,drop}()
we should just keep the connection and overwrite the stale record in
smbXsrv_client_global.tdb. It's basically a race with serverid_exists()

smbXsrv_client: ignore NAME_NOT_FOUND from smb2srv_client_connection_passed
If we hit a race, when a client disconnects the connection after the initial
SMB2 Negotiate request, before the connection is completely passed to
process serving the given client guid, the temporary smbd which accepted the
new connection may already detected the disconnect and exitted before
the long term smbd servicing the client guid was able to send the
MSG_SMBXSRV_CONNECTION_PASSED message.
and all connections belonging to the client guid were dropped,
because we called exit_server_cleanly().
Now we ignore NT_STATUS_OBJECT_NAME_NOT_FOUND from
smb2srv_client_connection_passed() and let the normal
event loop detect the broken connection, so that only
that connection is terminated (not the whole smbd process).

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.

pytest: add file removal helpers for TestCaseInTempDir
In several places we end a test by deleting a number of files and
directories, but we do it rather haphazardly with unintentionally
differing error handling. For example, in some tests we currently have
something like:
where if, for example, the removal of "b" fails, the removal of "c" will
not be attempted. That will result in the tearDown method raising an
exception, and we're no better off. If the above code is replaced with
self.rm_files('b')
self.rm_dirs('a', 'c')
the failure to remove 'b' will cause a test error, *unless* the failure
was due to a FileNotFoundError (a.k.a. an OSError with errno ENOENT),
in which case we ignore it, as was probably the original intention.
