32c333def9 CVE-2020-10760 dsdb: Ensure a proper talloc tree for saved controls
Otherwise a paged search on the GC port will fail as the ->data was

91453f110f dsdb: Allow "password hash userPassword schemes = CryptSHA256" to work on RHEL7
On RHEL7 crypt_r() will set errno.  This is a problem because the implementation of crypt_r()
in RHEL8 and elsewhere in libcrypt will return non-NULL but set errno on failure.

The workaround is to use crypt_rn(), provided only by libcrypt, which will return NULL
on failure, and so avoid checking errno in the non-failure case.

3b1b2e6046 s4:torture/smb2: make smb2.lock.replay_broken_windows more obvious
This test checks the SMB 2.1.0 behaviour of lock sequence checking,
which is only turned on for resilient handles.

Even Windows Server 2019 only implements lock sequence checking only
for resilient and persistent handles as a server.
While its client side uses lock sequence checking if it negotiated
multichannel with the server.

Hopefully this will be fixed in future Windows versions.

Make it clear that this test is supposed to pass against the legacy
Windows servers which violate the specification:

  [MS-SMB2] 3.3.5.14 Receiving an SMB2 LOCK Request

  ...

  ... if Open.IsResilient or Open.IsDurable or Open.IsPersistent is
  TRUE or if Connection.Dialect belongs to the SMB 3.x dialect family
  and Connection.ServerCapabilities includes
  SMB2_GLOBAL_CAP_MULTI_CHANNEL bit, the server SHOULD<314>
  perform lock sequence verification ...

  ...

  <314> Section 3.3.5.14: Windows 7 and Windows Server 2008 R2 perform
  lock sequence verification only when Open.IsResilient is TRUE.
  Windows 8 through Windows 10 v1909 and Windows Server 2012 through
  Windows Server v1909 perform lock sequence verification only when
  Open.IsResilient or Open.IsPersistent is TRUE.

Note <314> also applies to all versions (at least) up to Windows Server v2004.

Hopefully this will be fixed in future Windows versions and they
will avoid Note <314>.

6b6086bb58 s4:torture/smb2: fix and improve the smb2.lock.replay test
The test was wrong in that it used an invalid
lock sequence bucket (65) where it actually wanted
to use a valid on (64), and hence the test results
(which were adapted to the real responses) were not
quite logical.

This patch fixes this and also improves some of
the comments so that the flow of the patch becomes
a little more obvious.

even if the tgt session key uses different hmac.

Per [MS-SFU] 2.2.1 PA-FOR-USER the checksum is
always HMAC_MD5, and that's what windows 7 client
and MIT client send.

In heimdal both the client and kdc use the checksum of
the tgt key instead and therefore work with each other
but windows and MIT clients fail against heimdal KDC.

Windows KDC allows either checksum (HMAC_MD5 or from
tgt) so we should do the same to support all clients.

8b5e764413 selftest: add python S4U2Self tests including unkeyed checksums
To test the CRC32 I reverted the unkeyed-checksum fix (43958af1)
and the weak-crypto fix (389d1b97). Note that the unkeyed-md5
still worked even with weak-crypto disabled, and that the
unkeyed-sha1 never worked but I left it anyway.

004e7a1fee s4/rpc_server/dnsserver: Allow parsing of dnsProperty to fail gracefully
On (eg) the

DC=_msdcs.X.Y,CN=MicrosoftDNS,DC=ForestDnsZones,DC=X,DC=Y

record, in domains that have had a Microsoft Windows DC an attribute:

dNSProperty:: AAAAAAAAAAAAAAAAAQAAAJIAAAAAAAAA

000000 00 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00  >................<
000010 92 00 00 00 00 00 00 00                          >........<
000018

We, until samba 4.12, would parse this as:

pull returned Success
    dnsp_DnsProperty: struct dnsp_DnsProperty
        wDataLength              : 0x00000000 (0)
        namelength               : 0x00000000 (0)
        flag                     : 0x00000000 (0)
        version                  : 0x00000001 (1)
        id                       : DSPROPERTY_ZONE_NS_SERVERS_DA (146)
        data                     : union dnsPropertyData(case 0)
        name                     : 0x00000000 (0)
dump OK

However, the wDataLength is 0.  There is not anything in
[MS-DNSP] 2.3.2.1 dnsProperty to describe any special behaviour
for when the id suggests that there is a value, but wDataLength is 0.

https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-dnsp/445c7843-e4a1-4222-8c0f-630c230a4c80

We now fail to parse it, because we expect an entry with id DSPROPERTY_ZONE_NS_SERVERS_DA
to therefore have a valid DNS_ADDR_ARRAY (section 2.2.3.2.3).

As context we changed it in our commit fee5c6a424
because of bug https://bugzilla.samba.org/show_bug.cgi?id=14206
which was due to the artificial environment of the fuzzer.

Microsoft advises that Windows also fails to parse this, but
instead of failing the operation, the value is ignored.

Reported by Alex MacCuish.  Many thanks for your assistance in
tracking down the issue.

cb59b75bee s4: torture: SMB2. Add a new test that exposes interesting SD query behavior.
If we open a file without READ_CONTROL, requesting a security
descriptor fails with ACCESS_DENIED if any of the requested
bits OWNER|GROUP|DACL are set.

However, if we send zero as the requested bits then a
security descriptor is returned containing no data,
even though reading an SD should fail based on the
access permissions we have on the handle.

This has been tested against Windows 10, and also
passes on Samba - although in smbd we actually
read the SD off disk first, before nulling out
all the data we read. We shouldn't (we have
no rights to do so) and a subsequent commit
will fix this.

This was discovered when investigating the
smb2.winattr test, which currently relies
on exactly this behavior. It shouldn't
and the next commit will fix that.

I wanted to preserve the current smb2.winattr
behavior in a test though.

c83fafacbb s4/selftest: Modify samba4.blackbox.chgdcpass to use smbclient(s3)
Test was using smbclient4 but this fails when used in environments that
don't support SMB1. We use smbclient(s3) instead. There remains one
failure due to behaviour differences between the smbclients.

The behavioural changes are related not to SMB1/SMB2 but
commits d4ea637eb8 &
fce66b22ea

Perhaps we need to modify s3 smbclient in a similar way? This is however
something that deserves further discussion.

Move this failing part to a knownfail for the moment.

Also the corrosponding entry in skip_smb1_fail has been removed

samba4.blackbox.pkinit falls to pass in environments that don't support
SMB2 because of use (s4) smbclient4. Change test to use (s3) smbclient

Additionally a test within the test script test_kinit_trusts_heimdal.sh
explicitly uses smbclient4 which can't negotiate SMB1 in environments
that don't support it. Add knownfail to cater for this & also remove entry
from the skip file

Further reference the smbclient4 specific test is associated with

60aecca9a7 torture/smb2: delayed timestamp updates test: more then one write
Verify a close updates the write-time for subsequent writes after an initial
write started the delayed update logic.

This covers a scenario that will become relevant with the two subsequent
commits. The next commit:

  smbd: let mark_file_modified() always call trigger_write_time_update()

ensures that trigger_write_time_update() is not only called for the first write
on a file. Without that preaparatory change, the second commit:

  smbd: let delayed update handler also update on-disk timestamps

alone would cause this test to fail.

6f7d1d8a37 torture/smb2: Windows 2019 15 ms timestamp resolution
This test demonstrates that Windows has a timestamp resolution of ~15ms.

When a smaller amount of time than that has passed between modifying operations
on a file, it's not necessarily detectable on a Windows 2019 server that
implements immediate timestamp updates (no delayed magic).

Note that this test relies on a low latency SMB connection. Even with a low
latency connection of eg 1m there's a chance of 1/15 that the first part of the
test expecting no timestamp change fails as the writetime is updated.

Due to this timing dependency this test is skipped in Samba CI, but it is
preserved here for future SMB2 timestamps behaviour archealogists.

73fedf014b s4/torture: fix a timestamps test to work on ext filesystem
ext filesystem has a time_t limit of 15032385535 (0x0x37fffffff). From
Documentation/filesystems/ext4/inodes.rst:

  If the inode structure size ``sb->s_inode_size`` is larger than 128 bytes and
  the ``i_inode_extra`` field is large enough to encompass the respective
  ``i_[cma]time_extra`` field, the ctime, atime, and mtime inode fields are
  widened to 64 bits. Within this “extra” 32-bit field, the lower two bits are
  used to extend the 32-bit seconds field to be 34 bit wide; the upper 30 bits
  are used to provide nanosecond timestamp accuracy. Therefore, timestamps
  should not overflow until May 2446. ...

Changing the test to use the value 0x37fffffff instead of 100000000000 allows
running the test locally on ext filesytems.

With MIT library 1.18 the KDC no longer set
KRB5_KDB_FLAG_CANONICALIZE for enterprise principals which allows
us to not canonicalize them (like in Windows / Heimdal).

However, it now breaks the PAC signature verification as it was
wrongly done using canonical client rather than ticket client name.

The talloc_steal() in pdb_samba_dsdb_enum_aliasmem() is also unnecessary
for the same reason, but also incorrect, because it should be
dereferencing pmembers:

    talloc_steal(mem_ctx, *pmembers);

Furthermore, we should only assign to *pnum_members on success; otherwise
num_members is used uninitialized.

Samba 4.10 and later versions have a process restart capability to greatly
reduce the impact of crashes due to a NULL pointer de-reference or abort().

However SIGKILL was deliberatly omitted.

Sadly this is the most likely case, due to the OOM killer, as raised here:

https://lists.samba.org/archive/samba-technical/2019-November/134529.html

Subsequent discussion (offline) has been to agree that we should restart in
this case.
