8 months agos4:kdc: Add correct Asserted Identity SID in response to an S4U2Self request

s4:kdc: Add correct Asserted Identity SID in response to an S4U2Self request

I’m not sure exactly how this check was supposed to work. But in any
case, within fast_unwrap_request() the Heimdal KDC replaces the outer
padata with the padata from the inner FAST request. Hence, this check
does not accomplish anything useful: at no point should the KDC plugin
see the outer padata.

A couple of unwanted consequences resulted from this check. One was that
a client who sent empty FX‐FAST padata within the inner FAST request
would receive the *Authentication Authority* Asserted Identity SID
instead of the *Service* Asserted Identity SID. Another consequence was
that a client could in the same manner bypass the restriction on
performing S4U2Self with an RODC‐issued TGT.

Overall, samba_wdc_is_s4u2self_req() is somewhat of a hack. But the
Heimdal plugin API gives us nothing better to work with.

mdssvc: better support for search with mdfind from Macs

When searching Samba via Spotlight from a Mac with mdfind, only 50 results are
returned.

It seems the changes for bug #15342 where one step in the right
direction. There, a status indicator meaning "search is still being processed"
was implemented, returning a special status indicator (0x23) in a response, when
the query was still running in the backend, eg Elasticsearch, and we haven't got
any result when when the Mac already comes along asking for results of a query.

Turns out, we should also return 0x23, ie "search is still being processed" when
we have some initial search results from the backend. Otherwise mdfind will stop
querying for more results. It works in Finder, as the Finder by default employs
a "live" search where it just keeps polling for more results even after the
server returned an empty result set. The Finder just keeps on querying in some
interval, typically 4 seconds, and a Mac server Spotlight server might return
new results if new files where created that match the query, hence "live"
search.

Martin Schwenke [Tue, 15 Aug 2023 02:34:20 +0000 (12:34 +1000)]
ctdb-common: Set immediate mode for pcap capture

Fix a problem where ctdb_killtcp (almost always) fails to capture
packets with --enable-pcap and libpcap ≥ 1.9.1.  The problem is due to
a gradual change in libpcap semantics when using
pcap_get_selectable_fd(3PCAP) to get a file descriptor and then using
that file descriptor in non-blocking mode.

pcap_set_immediate_mode(3PCAP) says:

  pcap_set_immediate_mode() sets whether immediate mode should be set
  on a capture handle when the handle is activated.  In immediate
  mode, packets are always delivered as soon as they arrive, with no
  buffering.

and

  On Linux, with previous releases of libpcap, capture devices are
  always in immediate mode; however, in 1.5.0 and later, they are, by
  default, not in immediate mode, so if pcap_set_immediate_mode() is
  available, it should be used.

However, it wasn't until libpcap commit
2ade7676101366983bd4f86bc039ffd25da8c126 (before libpcap 1.9.1) that
it became a requirement to use pcap_set_immediate_mode(), even with a
timeout of 0.

More explanation in this libpcap issue comment:

  https://github.com/the-tcpdump-group/libpcap/issues/860#issuecomment-541204548

Do a configure check for pcap_set_immediate_mode() even though it has
existed for 10 years.  It is easy enough.

The issue is that without this, because the NC root was sorted
first in whatever chunk it appeared in but could have a 'high'
highwatermark, Azure AD Connect will send back the same

a zero reserved_usn, which makes Samba discard it.

The reserved_usn is now much less likely to ever be set because
the tmp_higest_usn is now always advancing.

s4-rpc_server/drsuapi: Only keep and invalidate replication cycle state for normal replication

This changes the GetNCChanges server to use a per-call state for
extended operations like RID_ALLOC or REPL_OBJ and only maintain
and (more importantly) invalidate the state during normal replication.

This allows REPL_OBJ to be called during a normal replication cycle
that continues using after that call, continuing with the same
highwatermark cookie.

Azure AD will do a sequence of (roughly)

* Normal replication (objects 1..100)
* REPL_OBJ (of 1 object)
* Normal replication (objects 101..200)

However, if there are more than 100 (in this example) objects in the
domain, and the second replication is required, the objects 1..100
are sent, as the replication state was invalidated by the REPL_OBJ call.

9 months agos3:smbd: fix multichannel connection passing race
Stefan Metzmacher [Thu, 3 Aug 2023 13:45:45 +0000 (15:45 +0200)]
s3:smbd: fix multichannel connection passing race

If a client opens multiple connection with the same
client guid in parallel, our connection passing is likely
to hit a race.

Assume we have 3 processes:

smbdA: This process already handles all connections for
       a given client guid
smbdB: This just received a new connection with an
       SMB2 neprot for the same client guid
smbdC: This also received a new connection with an
       SMB2 neprot for the same client guid

Now both smbdB and smbdC send a MSG_SMBXSRV_CONNECTION_PASS
message to smbdA. These messages contain the socket fd
for each connection.

While waiting for a MSG_SMBXSRV_CONNECTION_PASSED message
from smbdA, both smbdB and smbdC watch the smbXcli_client.tdb
record for changes (that also verifies smbdA stays alive).

Once one of them say smbdB received the MSG_SMBXSRV_CONNECTION_PASSED
message, the dbwrap_watch logic will wakeup smbdC in order to
let it recheck the smbXcli_client.tdb record in order to
handle the case where smbdA died or deleted its record.

Now smbdC rechecks the smbXcli_client.tdb record, but it
was not woken because of a problem with smbdA. It meant
that smbdC sends a MSG_SMBXSRV_CONNECTION_PASS message
including the socket fd again.

As a result smbdA got the socket fd from smbdC twice (or even more),
and creates two (or more) smbXsrv_connection structures for the
same low level tcp connection. And it also sends more than one
SMB2 negprot response. Depending on the tevent logic, it will
use different smbXsrv_connection structures to process incoming
requests. And this will almost immediately result in errors.

The typicall error is:
 smb2_validate_sequence_number: smb2_validate_sequence_number: bad message_id 2 (sequence id 2) (granted = 1, low = 1, range = 1)

But other errors would also be possible.

The detail that leads to the long delays on the client side is
that our smbd_server_connection_terminate_ex() code will close
only the fd of a single smbXsrv_connection, but the refcount
on the socket fd in the kernel is still not 0, so the tcp
connection is still alive...

Now we remember the server_id of the process that we send
the MSG_SMBXSRV_CONNECTION_PASS message to. And just keep
watching the smbXcli_client.tdb record if the server_id
don't change. As we just need more patience to wait for
the MSG_SMBXSRV_CONNECTION_PASSED message.

1. sudo samba-tool ntacl get .

gdb said it goes through aio_pthread_openat_fn() @ vfs_aio_pthread.c[2],

'sconn->client' memory is allocated when a new connection is accpeted:

While running local commands looks like it would not go through
smbXsrv_client_create so the 'client' is null, segfault might happen.
We should not dereference 'client->server_multi_channel_enabled',

ctdb-tools: Improve printing of multi-line event script output

Multi-line output currently prints like this:

  OUTPUT: aaa
bbb
ccc

This is less beautiful than it could be.

Instead, print multi-line output with no inlining and each line
indented:

  OUTPUT:
    aaa
    bbb
    ccc

However, continue to inline single line output:

  OUTPUT: foo
