73f3ece8b2 s4-drs: Make drs_ObjectIdentifier_to_dn() safer and able to cope with DummyDN values
We want to totally ignore the string DN if there is a GUID,
as clients like "Microsoft Azure AD connect cloud sync" will
set a literal "DummyDN" string.

aee2039e63 s4-dsdb: rework drs_ObjectIdentifier_to_dn() into drs_ObjectIdentifier_to_dn_and_nc_root()
This make this funciton the gatekeeper between the wire format and the
internal struct ldb_dn, checking if the DN exists and which NC
it belongs to along the way, and presenting only a DB-returned
DN for internal processing.

3d3d01cda8 s3: smbd: Tweak openat_pathref_dirfsp_nosymlink() to NULL out fsp->fsp_name after calling fd_close() on intermediate directories, rather than before.
vfs_virusfilter expects a non-NULL fsp->fsp_name to use for printing debugs
(it always indirects fsp->fsp_name). vfs_fruit also does the same, so would
also crash in fruit_close() with 'debug level = 10' and vfs_default:VFS_OPEN_HOW_RESOLVE_NO_SYMLINKS = no
set (we don't test with that which is why we haven't noticed
this before).

The use of reload_services() has a lot of side effects, e.g. reopen of

It was also unloading the user and registry shares we loaded a few lines
above.

17bbd6ec4c smbd: Add "posix" flag to openat_pathref_dirfsp_nosymlink()
Don't do the get_real_filename() retry if we're in posix context of if
the connection is case sensitive.

The whole concept of case sensivity blows my brain. In SMB1 without
posix extensions it's a per-request thing. In SMB2 without posix
extensions this should just depend on "case sensitive = yes/no", and
in future SMB2 posix extensions this will become a per-request thing
again, depending on the existence of the posix create context.

Then there are other semantics that are attached to posix-ness, which
have nothing to do with case sensivity. See for example merge request
2819 and bug 8776, or commit f0e1137425. Also see
check_path_syntax_internal().

This patch uses the same flags as openat_pathref_fsp_case_insensitive()
does, but I am 100% certain this is wrong in a subtle way.

fde745ec34 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.

The intention of this option was to hide *files*. Before this patch we
also hide directories where new files are dropped.

This is a change in behaviour, but I think this option is niche enough
to justify not adding another parameter that we then need to test. If
workflows break with this change and people depend on directories also
to be hidden, we can still add the additional option value required.

We later subtract 8 when calculating the length of the output message
buffer. If padlength is excessively high, this calculation can underflow
and result in a very large positive value.

Now we properly constrain the value of padlength so underflow shouldn't
be possible.

e232ba946f 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().

8591d94243 smbXsrv_client: notify a different node to drop a connection by client guid.
If a client disconnected all its interfaces and reconnects when

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

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

caused a connection with the same client-guid to be rejected by
ctdb node 1. Node 1 rejects the SMB2 Negotiate with
NT_STATUS_NOT_SUPPORTED, because passing the multi-channel connection
to a different node is not supported.

a8ed244148 s3: torture: Add a comprehensive SMB1 DFS path torture tester.
smbtorture3 test is: SMB1-DFS-PATHS

Tests open, and then all 4 methods of renaming/hardlinking
files:

1). SMBmv
2). SMBtrans2 SETPATHINFO
3). SMBtrans2 SETFILEINFO
4). SMBntrename

Also added a test for SMB1findfirst.

smbtorture3 test is: SMB1-DFS-SEARCH-PATHS.

What this shows is that Windows strips off the
SMB1findfirst mask *before* calling the DFS path
parser (smbd currently does not).

Added so we know how to fix the server code to match Windows
behavior in parsing DFS paths in different calls going forward.

Passes fully against Windows. Adds knownfails for smbd.

e492986661 s3: torture: Add a comprehensive SMB2 DFS path torture tester.
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.

- 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

96e2a82760 s3:smbd: only clear LEASE_READ if there's no read lease is left
If contend_level2_oplocks_begin_default() skips break it's
own lease, we should not clear SHARE_MODE_LEASE_READ
in share_mode_data->flags.

Otherwise that lease won't see any lease break notifications
for writes from other clients (file handles not using the same lease
key).

So we need to count the number existing read leases (including
the one with the same lease key) in order to know it's
safe to clear SMB2_LEASE_READ/SHARE_MODE_LEASE_READ.

Otherwise the next run (likely from another client)
will get the wrong result from file_has_read_lease().

23bc760ec5 CI: add a test trying to delete a stream on a pathref ("stat open") handle
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.

e6957c1d47 samba-tool user: Accomodate missing unicodePwd in getpassword command
To allow for the NT hash not being stored when NTLM authentication is
disabled, we use the AES256 key instead for verification against the
other packages if the unicodePwd attribute is not present.

d2a473a7b7 dsdb: Allow password history and password changes without an NT hash
We now allow this to be via the ENCTYPE_AES256_CTS_HMAC_SHA1_96 hash instead
which allows us to decouple Samba from the unsalted NT hash for
organisations that are willing to take this step (for user accounts).

(History checking is limited to the last three passwords only, as
ntPwdHistory is limited to NT hash values, and the PrimaryKerberosCtr4
package only stores three sets of keys.)

Since we don't store a salt per-key, but only a single salt, the check
will fail for a previous password if the account was renamed prior to a
newer password being set.

808a7b8b76 s3: VFS: streams_xattr: Add the same accommodation to streams_xattr_unlinkat() as used in streams_xattr_renameat().
vfs_fruit passes a synthetic filename here where smb_fname->fsp==NULL
when configured to use "fruit:resource = stream" so we need to use
synthetic_pathref() to get an fsp on the smb_fname->base_name
in order to call SMB_VFS_FREMOVEXATTR().

This is the same change we already use in streams_xattr_renameat()
and streams_xattr_stat(), the other pathname operations we implement
here.

04e0e02c69 srvsvc: Announce [username] in NetShareEnum
This patch has two flaws: First, it does not cover api_RNetShareEnum()
for SMB1, and the second one is: To make this elegant, we would have
to restructure our share handling. It is really only listing shares
for which we have to pull in everything from smb.conf, registry,
usershares and potentially printers. What we should do is modify our
loadparm handling to only load share definitions on demand and for
listing shares handle all the potential sources specially. Add code
that walks the registry shares without adding them to our services
list and so on.

This patch is the quick&dirty way to fix the bug, the alternative
would be weeks or more. And hopefully nobody notices the SMB1
problem...

A simple degenerate case for our compressor has been a large number of
repeated bytes that will match the maximum length (~64k) at all 8192
search positions, 8191 of which searches are in vain because the
matches are not of greater length than the first one.

Here we recognise the inevitable and reduce runtime proportionately.

45af51fd6e selftest: Cope with LM hash not being stored in the tombstone_reanimation test
The removal of LM hash storage changes the expected metadata.

We do not need to track these values exactly to prove the
behaviour here.

This is not due to the changes in password_hash directly, which in
update_final_msg() sets DSDB_FLAG_INTERNAL_FORCE_META_DATA to force
a push out of the removed attribute to the replication state.

However at the stage of a subsequent LDAP Delete there is no longer
a lmPwdHistory nor dBCSPwd attribute, in the directory, so there is
no subsequent version bump to remove them when building a tombstone.

Samba's behaviour is different to that seen by Metze on windows 2022,
where he sees dBCSPwd removed (for the no LM store case) but
lmPwdHistory kept.  We in Samba choose to differ, not storing an
ambiguous LM hsitory (of "" values likely), so allowing any version
for these two attributes is the sensible choice.

40f2070d3b s4:auth: let authenticate_ldap_simple_bind() pass down the mapped nt4names
authenticate_ldap_simple_bind*() needs to pass the
result of the cracknames operation into the auth stack
as user_info->client.{account,domain}_name, because
user_info->client.{account,domain}_name is also used
when forwarding the request via netrLogonSamLogon*
to a remote server, for exactly that the values are
also used in order to map a AUTH_PASSWORD_PLAIN into
AUTH_PASSWORD_RESPONSE, where the NTLMv2 response
contains the account and domain names passed in the
netr_IdentityInfo value.

Otherwise it would not be possible to forward the
LDAP simple bind authentication request to a remote
DC.

Currently this only applies to an RODC that forwards
the request to an RWDC.

But note that LDAP simple binds (as on Windows) only
work for users in the DCs forest, as the DsCrackNames
need to work and it can't work for users of remote
forests. I tested that in a DC of a forest root domain,
if rejected the LDAP simple bind against a different forest,
but allowed it for a users of a child domain in the
same forest. The NTLMSSP bind worked in both cases.

mapped_state is a special hack for authenticate_ldap_simple_bind_send()

This doesn't apply here. We should also handle wbinfo -a

even if the account belongs to the local sam.

With this change the behavior is consistent also locally on DCs and
also an RODC can handle these requests locally for cached accounts.
