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 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.

What this shows is that Windows strips off the

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.

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.

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

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.

Since we don't store a salt per-key, but only a single salt, the check

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...

637e7cbdba lzxpress: compress shortcut if we've reached maximum length
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.

5fe341d2d6 s3: torture: Add 2 new tests SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-NO, SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-YES.
We currently allow setting the delete on close bit for
a directory containing only explicitly hidden/vetoed files
in the case where "delete veto files = yes" *and*
"delete veto files = no". For the "delete veto files = no"
case we should be denying setting the delete on close bit
when the client tries to set it (that's the only time Windows
looks at the bit and returns an error to the user). We
already do the in the dangling symlink case, we just
missed it in the !is_visible_fsp() case.

Mark SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-NO as knownfail
for now.

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.

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

434e6d4b4b smbd: Only file_free() a self-created fsp in create_file_unixpath()
This fixes a use-after-free in smb_full_audit_create_file() when
calling SMB_VFS_CREATE_FILE with fsp->fsp_name as smb_fname.

create_file_unixpath() has this comment:

 * This is really subtle. If someone passes in an smb_fname
 * where smb_fname actually is taken from fsp->fsp_name, then
 * the lifetime of these objects is meant to be the same.

so it seems legitimate to call CREATE_FILE this way.

When CREATE_FILE runs into an error, create_file_unixpath() does a
file_free, which also takes fsp->fsp_name with
it. smb_full_audit_create_file() wants to log the failure including
the smb_fname after NEXT_CREATE_FILE has exited, but this will then
use the already free'ed data.

Fix by only doing the file_free() on an fsp that
create_file_unixpath() created itself.

44cc9fb0e0 s3: tests: Add a new test test_msdfs_rename() that does simple renames on MSDFS root shares.
We fail this on SMB2 for a subtle reason.

Our client code called from smbclient only sets the SMB2_HDR_FLAG_DFS flag
in the outgoing packet on the SMB2_CREATE call, and SMB2 rename does the
following operations:

SMB2_CREATE(src_path) // We set SMB2_HDR_FLAG_DFS here for a MSDFS share.
SMB2_SETINFO: SMB2_FILE_RENAME_INFO(dst_path). // We don't set SMB2_HDR_FLAG_DFS

However, from smbclient, dst_path is a MSDFS path but we don't set the flag,
so even though the rename code inside smbd will cope with a MSDFS path
(as used in the SMB1 SMBmv call) it fails as the correct flag isn't set.

Add knownfail selftest/knownfail.d/msdfs-rename.

Note we need to add the new test to "selftest/knownfail.d/smb1-tests"
as test_smbclient_s3.sh is run against the (ad_member|nt4_member)
environments first using NT1 (SMB1) protocol and then using SMB3,
but the (ad_member|nt4_member) environments don't support SMB1.
Seems a bit strange to me, but all the other SMB1 tests inside
test_smbclient_s3.sh have already been added to "selftest/knownfail.d/smb1-tests"
so just go with the test environment.

This first gets the clock_gettime_mono() value, converts to an NTTIME (as
this is what is stored in the dos attribute EA), then mixes in 8 bits of
randomness shifted up by 55 bits to cope with poor resolution clocks to
avoid duplicate inodes.

Using 8 bits of randomness on top of an NTTIME gives us around 114
years headroom. We can now guarentee returning a itime-based

0a546be052 CVE-2020-25717: s3:auth: Fallback to a SID/UID based mapping if the named based lookup fails
Before the CVE-2020-25717 fixes we had a fallback from
getpwnam('DOMAIN\user') to getpwnam('user') which was very dangerous and
unpredictable.

Now we do the fallback based on sid_to_uid() followed by
getpwuid() on the returned uid.

This obsoletes 'username map [script]' based workaround adviced
for CVE-2020-25717, when nss_winbindd is not used or
idmap_nss is actually used.

In future we may decide to prefer or only do the SID/UID based
lookup, but for now we want to keep this unchanged as much as possible.

For example, with the default sPNMappings, cifs/ is an alias pointing to
host/, meaning if there is no cifs/example.com SPN, the host/example.com
one will be used instead. A user can add the cifs/example.com SPN only
if they can also change the host/example.com one (because adding the
cifs/ effectively changes the host/). The reverse is refused in all cases,
unless they happen to be on the same object. That is, if there is a

We already know duplicate sAMAccountNames and UserPrincipalNames are bad,
but we also have to check against the values these imply in each other.

For example, imagine users with SAM account names "Alice" and "Bob" in
the realm "example.com". If they do not have explicit UPNs, by the logic
of MS-ADTS 5.1.1.1.1 they use the implict UPNs "alice@example.com" and
"bob@example.com", respectively. If Bob's UPN gets set to
"alice@example.com", it will clash with Alice's implicit one.

Therefore we refuse to allow a UPN that implies an existing SAM account
name and vice versa.
