6 This is a security release containing one additional
7 regression fix for the security release 4.2.10.
9 This fixes a regression that prevents things like 'net ads join'
10 from working against a Windows 2003 domain.

23 Release Notes for Samba 4.2.10
25 ==============================
28 This is a security release in order to address the following CVEs:
30 o CVE-2015-5370 (Multiple errors in DCE-RPC code)
32 o CVE-2016-2110 (Man in the middle attacks possible with NTLMSSP)
34 o CVE-2016-2111 (NETLOGON Spoofing Vulnerability)
36 o CVE-2016-2112 (LDAP client and server don't enforce integrity)
38 o CVE-2016-2113 (Missing TLS certificate validation)
40 o CVE-2016-2114 ("server signing = mandatory" not enforced)
42 o CVE-2016-2115 (SMB IPC traffic is not integrity protected)
44 o CVE-2016-2118 (SAMR and LSA man in the middle attacks possible)
46 The number of changes are rather huge for a security release,
47 compared to typical security releases.
49 Given the number of problems and the fact that they are all related
50 to man in the middle attacks we decided to fix them all at once
51 instead of splitting them.
53 In order to prevent the man in the middle attacks it was required
54 to change the (default) behavior for some protocols. Please see the
55 "New smb.conf options" and "Behavior changes" sections below.
63 Versions of Samba from 3.6.0 to 4.4.0 inclusive are vulnerable to
64 denial of service attacks (crashes and high cpu consumption)
65 in the DCE-RPC client and server implementations. In addition,
66 errors in validation of the DCE-RPC packets can lead to a downgrade
67 of a secure connection to an insecure one.
69 While we think it is unlikely, there's a nonzero chance for
70 a remote code execution attack against the client components,
71 which are used by smbd, winbindd and tools like net, rpcclient and
72 others. This may gain root access to the attacker.
74 The above applies all possible server roles Samba can operate in.
76 Note that versions before 3.6.0 had completely different marshalling
77 functions for the generic DCE-RPC layer. It's quite possible that
78 that code has similar problems!
80 The downgrade of a secure connection to an insecure one may
81 allow an attacker to take control of Active Directory object
82 handles created on a connection created from an Administrator
83 account and re-use them on the now non-privileged connection,
84 compromising the security of the Samba AD-DC.
88 There are several man in the middle attacks possible with
89 NTLMSSP authentication.
91 E.g. NTLMSSP_NEGOTIATE_SIGN and NTLMSSP_NEGOTIATE_SEAL
92 can be cleared by a man in the middle.
94 This was by protocol design in earlier Windows versions.
96 Windows Server 2003 RTM and Vista RTM introduced a way
97 to protect against the trivial downgrade.
99 See MsvAvFlags and flag 0x00000002 in
100 https://msdn.microsoft.com/en-us/library/cc236646.aspx
102 This new feature also implies support for a mechlistMIC
103 when used within SPNEGO, which may prevent downgrades
104 from other SPNEGO mechs, e.g. Kerberos, if sign or
105 seal is finally negotiated.
107 The Samba implementation doesn't enforce the existence of
108 required flags, which were requested by the application layer,
109 e.g. LDAP or SMB1 encryption (via the unix extensions).
110 As a result a man in the middle can take over the connection.
111 It is also possible to misguide client and/or
112 server to send unencrypted traffic even if encryption
113 was explicitly requested.
115 LDAP (with NTLMSSP authentication) is used as a client
116 by various admin tools of the Samba project,
117 e.g. "net", "samba-tool", "ldbsearch", "ldbedit", ...
119 As an active directory member server LDAP is also used
120 by the winbindd service when connecting to domain controllers.
122 Samba also offers an LDAP server when running as
123 active directory domain controller.
125 The NTLMSSP authentication used by the SMB1 encryption
126 is protected by smb signing, see CVE-2015-5296.
130 It's basically the same as CVE-2015-0005 for Windows:
132 The NETLOGON service in Microsoft Windows Server 2003 SP2,
133 Windows Server 2008 SP2 and R2 SP1, and Windows Server 2012 Gold
134 and R2, when a Domain Controller is configured, allows remote
135 attackers to spoof the computer name of a secure channel's
136 endpoint, and obtain sensitive session information, by running a
137 crafted application and leveraging the ability to sniff network
138 traffic, aka "NETLOGON Spoofing Vulnerability".
140 The vulnerability in Samba is worse as it doesn't require
141 credentials of a computer account in the domain.
143 This only applies to Samba running as classic primary domain controller,
144 classic backup domain controller or active directory domain controller.
146 The security patches introduce a new option called "raw NTLMv2 auth"
147 ("yes" or "no") for the [global] section in smb.conf.
148 Samba (the smbd process) will reject client using raw NTLMv2
149 without using NTLMSSP.
151 Note that this option also applies to Samba running as
152 standalone server and member server.
154 You should also consider using "lanman auth = no" (which is already the default)
155 and "ntlm auth = no". Have a look at the smb.conf manpage for further details,
156 as they might impact compatibility with older clients. These also
157 apply for all server roles.
161 Samba uses various LDAP client libraries, a builtin one and/or the system
162 ldap libraries (typically openldap).
164 As active directory domain controller Samba also provides an LDAP server.
166 Samba takes care of doing SASL (GSS-SPNEGO) authentication with Kerberos or NTLMSSP
167 for LDAP connections, including possible integrity (sign) and privacy (seal)
170 Samba has support for an option called "client ldap sasl wrapping" since version
171 3.2.0. Its default value has changed from "plain" to "sign" with version 4.2.0.
173 Tools using the builtin LDAP client library do not obey the
174 "client ldap sasl wrapping" option. This applies to tools like:
175 "samba-tool", "ldbsearch", "ldbedit" and more. Some of them have command line
176 options like "--sign" and "--encrypt". With the security update they will
177 also obey the "client ldap sasl wrapping" option as default.
179 In all cases, even if explicitly request via "client ldap sasl wrapping",
180 "--sign" or "--encrypt", the protection can be downgraded by a man in the
183 The LDAP server doesn't have an option to enforce strong authentication
184 yet. The security patches will introduce a new option called
185 "ldap server require strong auth", possible values are "no",
186 "allow_sasl_over_tls" and "yes".
188 As the default behavior was as "no" before, you may
189 have to explicitly change this option until all clients have
190 been adjusted to handle LDAP_STRONG_AUTH_REQUIRED errors.
191 Windows clients and Samba member servers already use
192 integrity protection.
196 Samba has support for TLS/SSL for some protocols:
197 ldap and http, but currently certificates are not
198 validated at all. While we have a "tls cafile" option,
199 the configured certificate is not used to validate
200 the server certificate.
202 This applies to ldaps:// connections triggered by tools like:
203 "ldbsearch", "ldbedit" and more. Note that it only applies
204 to the ldb tools when they are built as part of Samba or with Samba
205 extensions installed, which means the Samba builtin LDAP client library is
208 It also applies to dcerpc client connections using ncacn_http (with https://),
209 which are only used by the openchange project. Support for ncacn_http
210 was introduced in version 4.2.0.
212 The security patches will introduce a new option called
213 "tls verify peer". Possible values are "no_check", "ca_only",
214 "ca_and_name_if_available", "ca_and_name" and "as_strict_as_possible".
216 If you use the self-signed certificates which are auto-generated
217 by Samba, you won't have a crl file and need to explicitly
218 set "tls verify peer = ca_and_name".
222 Due to a regression introduced in Samba 4.0.0,
223 an explicit "server signing = mandatory" in the [global] section
224 of the smb.conf was not enforced for clients using the SMB1 protocol.
226 As a result it does not enforce smb signing and allows man in the middle attacks.
228 This problem applies to all possible server roles:
229 standalone server, member server, classic primary domain controller,
230 classic backup domain controller and active directory domain controller.
232 In addition, when Samba is configured with "server role = active directory domain controller"
233 the effective default for the "server signing" option should be "mandatory".
235 During the early development of Samba 4 we had a new experimental
236 file server located under source4/smb_server. But before
237 the final 4.0.0 release we switched back to the file server
240 But the logic for the correct default of "server signing" was not
241 ported correctly ported.
243 Note that the default for server roles other than active directory domain
244 controller, is "off" because of performance reasons.
248 Samba has an option called "client signing", this is turned off by default
249 for performance reasons on file transfers.
251 This option is also used when using DCERPC with ncacn_np.
253 In order to get integrity protection for ipc related communication
254 by default the "client ipc signing" option is introduced.
255 The effective default for this new option is "mandatory".
257 In order to be compatible with more SMB server implementations,
258 the following additional options are introduced:
259 "client ipc min protocol" ("NT1" by default) and
260 "client ipc max protocol" (the highest support SMB2/3 dialect by default).
261 These options overwrite the "client min protocol" and "client max protocol"
262 options, because the default for "client max protocol" is still "NT1".
263 The reason for this is the fact that all SMB2/3 support SMB signing,
264 while there are still SMB1 implementations which don't offer SMB signing
265 by default (this includes Samba versions before 4.0.0).
267 Note that winbindd (in versions 4.2.0 and higher) enforces SMB signing
268 against active directory domain controllers despite of the
269 "client signing" and "client ipc signing" options.
271 o CVE-2016-2118 (a.k.a. BADLOCK):
273 The Security Account Manager Remote Protocol [MS-SAMR] and the
274 Local Security Authority (Domain Policy) Remote Protocol [MS-LSAD]
275 are both vulnerable to man in the middle attacks. Both are application level
276 protocols based on the generic DCE 1.1 Remote Procedure Call (DCERPC) protocol.
278 These protocols are typically available on all Windows installations
279 as well as every Samba server. They are used to maintain
280 the Security Account Manager Database. This applies to all
281 roles, e.g. standalone, domain member, domain controller.
283 Any authenticated DCERPC connection a client initiates against a server
284 can be used by a man in the middle to impersonate the authenticated user
285 against the SAMR or LSAD service on the server.
287 The client chosen application protocol, auth type (e.g. Kerberos or NTLMSSP)
288 and auth level (NONE, CONNECT, PKT_INTEGRITY, PKT_PRIVACY) do not matter
289 in this case. A man in the middle can change auth level to CONNECT
290 (which means authentication without message protection) and take over
293 As a result, a man in the middle is able to get read/write access to the
294 Security Account Manager Database, which reveals all passwords
295 and any other potential sensitive information.
297 Samba running as an active directory domain controller is additionally
298 missing checks to enforce PKT_PRIVACY for the
299 Directory Replication Service Remote Protocol [MS-DRSR] (drsuapi)
300 and the BackupKey Remote Protocol [MS-BKRP] (backupkey).
301 The Domain Name Service Server Management Protocol [MS-DNSP] (dnsserver)
302 is not enforcing at least PKT_INTEGRITY.
308 allow dcerpc auth level connect (G)
310 This option controls whether DCERPC services are allowed to be used with
311 DCERPC_AUTH_LEVEL_CONNECT, which provides authentication, but no per
312 message integrity nor privacy protection.
314 Some interfaces like samr, lsarpc and netlogon have a hard-coded default
315 of no and epmapper, mgmt and rpcecho have a hard-coded default of yes.
317 The behavior can be overwritten per interface name (e.g. lsarpc,
318 netlogon, samr, srvsvc, winreg, wkssvc ...) by using
319 'allow dcerpc auth level connect:interface = yes' as option.
321 This option yields precedence to the implementation specific restrictions.
322 E.g. the drsuapi and backupkey protocols require DCERPC_AUTH_LEVEL_PRIVACY.
323 The dnsserver protocol requires DCERPC_AUTH_LEVEL_INTEGRITY.
325 Default: allow dcerpc auth level connect = no
327 Example: allow dcerpc auth level connect = yes
329 client ipc signing (G)
331 This controls whether the client is allowed or required to use
332 SMB signing for IPC$ connections as DCERPC transport. Possible
333 values are auto, mandatory and disabled.
335 When set to mandatory or default, SMB signing is required.
337 When set to auto, SMB signing is offered, but not enforced and
338 if set to disabled, SMB signing is not offered either.
340 Connections from winbindd to Active Directory Domain Controllers
341 always enforce signing.
343 Default: client ipc signing = default
345 client ipc max protocol (G)
347 The value of the parameter (a string) is the highest protocol level that will
348 be supported for IPC$ connections as DCERPC transport.
350 Normally this option should not be set as the automatic negotiation phase
351 in the SMB protocol takes care of choosing the appropriate protocol.
353 The value default refers to the latest supported protocol, currently SMB3_11.
355 See client max protocol for a full list of available protocols.
356 The values CORE, COREPLUS, LANMAN1, LANMAN2 are silently upgraded to NT1.
358 Default: client ipc max protocol = default
360 Example: client ipc max protocol = SMB2_10
362 client ipc min protocol (G)
364 This setting controls the minimum protocol version that the will be
365 attempted to use for IPC$ connections as DCERPC transport.
367 Normally this option should not be set as the automatic negotiation phase
368 in the SMB protocol takes care of choosing the appropriate protocol.
370 The value default refers to the higher value of NT1 and the
371 effective value of "client min protocol".
373 See client max protocol for a full list of available protocols.
374 The values CORE, COREPLUS, LANMAN1, LANMAN2 are silently upgraded to NT1.
376 Default: client ipc min protocol = default
378 Example: client ipc min protocol = SMB3_11
380 ldap server require strong auth (G)
382 The ldap server require strong auth defines whether the
383 ldap server requires ldap traffic to be signed or
384 signed and encrypted (sealed). Possible values are no,
385 allow_sasl_over_tls and yes.
387 A value of no allows simple and sasl binds over all transports.
389 A value of allow_sasl_over_tls allows simple and sasl binds (without sign or seal)
390 over TLS encrypted connections. Unencrypted connections only
391 allow sasl binds with sign or seal.
393 A value of yes allows only simple binds over TLS encrypted connections.
394 Unencrypted connections only allow sasl binds with sign or seal.
396 Default: ldap server require strong auth = yes
400 This parameter determines whether or not smbd(8) will allow SMB1 clients
401 without extended security (without SPNEGO) to use NTLMv2 authentication.
403 If this option, lanman auth and ntlm auth are all disabled, then only
404 clients with SPNEGO support will be permitted. That means NTLMv2 is only
405 supported within NTLMSSP.
407 Default: raw NTLMv2 auth = no
411 This controls if and how strict the client will verify the peer's
412 certificate and name. Possible values are (in increasing order): no_check,
413 ca_only, ca_and_name_if_available, ca_and_name and as_strict_as_possible.
415 When set to no_check the certificate is not verified at all,
416 which allows trivial man in the middle attacks.
418 When set to ca_only the certificate is verified to be signed from a ca
419 specified in the "tls ca file" option. Setting "tls ca file" to a valid file
420 is required. The certificate lifetime is also verified. If the "tls crl file"
421 option is configured, the certificate is also verified against
424 When set to ca_and_name_if_available all checks from ca_only are performed.
425 In addition, the peer hostname is verified against the certificate's
426 name, if it is provided by the application layer and not given as
427 an ip address string.
429 When set to ca_and_name all checks from ca_and_name_if_available are performed.
430 In addition the peer hostname needs to be provided and even an ip
431 address is checked against the certificate's name.
433 When set to as_strict_as_possible all checks from ca_and_name are performed.
434 In addition the "tls crl file" needs to be configured. Future versions
435 of Samba may implement additional checks.
437 Default: tls verify peer = as_strict_as_possible
439 tls priority (G) (backported from Samba 4.3 to Samba 4.2)
441 This option can be set to a string describing the TLS protocols to be
442 supported in the parts of Samba that use GnuTLS, specifically the AD DC.
444 The default turns off SSLv3, as this protocol is no longer considered
445 secure after CVE-2014-3566 (otherwise known as POODLE) impacted SSLv3 use
446 in HTTPS applications.
448 The valid options are described in the GNUTLS Priority-Strings
449 documentation at http://gnutls.org/manual/html_node/Priority-Strings.html
451 Default: tls priority = NORMAL:-VERS-SSL3.0
457 o The default auth level for authenticated binds has changed from
458 DCERPC_AUTH_LEVEL_CONNECT to DCERPC_AUTH_LEVEL_INTEGRITY.
459 That means ncacn_ip_tcp:server is now implicitly the same
460 as ncacn_ip_tcp:server[sign] and offers a similar protection
461 as ncacn_np:server, which relies on smb signing.
463 o The following constraints are applied to SMB1 connections:
465 - "client lanman auth = yes" is now consistently
466 required for authenticated connections using the
467 SMB1 LANMAN2 dialect.
468 - "client ntlmv2 auth = yes" and "client use spnego = yes"
469 (both the default values), require extended security (SPNEGO)
470 support from the server. That means NTLMv2 is only used within
473 o Tools like "samba-tool", "ldbsearch", "ldbedit" and more obey the
474 default of "client ldap sasl wrapping = sign". Even with
475 "client ldap sasl wrapping = plain" they will automatically upgrade
476 to "sign" when getting LDAP_STRONG_AUTH_REQUIRED from the LDAP

579 Release Notes for Samba 4.2.9
581 =============================
584 This is a security release in order to address the following CVEs:
586 o CVE-2015-7560 (Incorrect ACL get/set allowed on symlink path)
587 o CVE-2016-0771 (Out-of-bounds read in internal DNS server)
594 All versions of Samba from 3.2.0 to 4.4.0rc3 inclusive are vulnerable to
595 a malicious client overwriting the ownership of ACLs using symlinks.
597 An authenticated malicious client can use SMB1 UNIX extensions to
598 create a symlink to a file or directory, and then use non-UNIX SMB1
599 calls to overwrite the contents of the ACL on the file or directory
603 All versions of Samba from 4.0.0 to 4.4.0rc3 inclusive, when deployed as
604 an AD DC and choose to run the internal DNS server, are vulnerable to an
605 out-of-bounds read issue during DNS TXT record handling caused by users
606 with permission to modify DNS records.
608 A malicious client can upload a specially constructed DNS TXT record,
609 resulting in a remote denial-of-service attack. As long as the affected
610 TXT record remains undisturbed in the Samba database, a targeted DNS
611 query may continue to trigger this exploit.
613 While unlikely, the out-of-bounds read may bypass safety checks and
614 allow leakage of memory from the server in the form of a DNS TXT reply.
616 By default only authenticated accounts can upload DNS records,
617 as "allow dns updates = secure only" is the default.
618 Any other value would allow anonymous clients to trigger this
619 bug, which is a much higher risk.

734 Release Notes for Samba 4.2.7
736 =============================
739 This is a security release in order to address the following CVEs:
741 o CVE-2015-3223 (Denial of service in Samba Active Directory
743 o CVE-2015-5252 (Insufficient symlink verification in smbd)
744 o CVE-2015-5299 (Missing access control check in shadow copy
746 o CVE-2015-5296 (Samba client requesting encryption vulnerable
748 o CVE-2015-8467 (Denial of service attack against Windows
749 Active Directory server)
750 o CVE-2015-5330 (Remote memory read in Samba LDAP server)
752 Please note that if building against a system libldb, the required
753 version has been bumped to ldb-1.1.24. This is needed to ensure
754 we build against a system ldb library that contains the fixes
755 for CVE-2015-5330 and CVE-2015-3223.
762 All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
763 ldb versions up to 1.1.23 inclusive) are vulnerable to
764 a denial of service attack in the samba daemon LDAP server.
766 A malicious client can send packets that cause the LDAP server in the
767 samba daemon process to become unresponsive, preventing the server
768 from servicing any other requests.
770 This flaw is not exploitable beyond causing the code to loop expending
774 All versions of Samba from 3.0.0 to 4.3.2 inclusive are vulnerable to
775 a bug in symlink verification, which under certain circumstances could
776 allow client access to files outside the exported share path.
778 If a Samba share is configured with a path that shares a common path
779 prefix with another directory on the file system, the smbd daemon may
780 allow the client to follow a symlink pointing to a file or directory
781 in that other directory, even if the share parameter "wide links" is
782 set to "no" (the default).
785 All versions of Samba from 3.2.0 to 4.3.2 inclusive are vulnerable to
786 a missing access control check in the vfs_shadow_copy2 module. When
787 looking for the shadow copy directory under the share path the current
788 accessing user should have DIRECTORY_LIST access rights in order to
789 view the current snapshots.
791 This was not being checked in the affected versions of Samba.
794 Versions of Samba from 3.2.0 to 4.3.2 inclusive do not ensure that
795 signing is negotiated when creating an encrypted client connection to
798 Without this a man-in-the-middle attack could downgrade the connection
799 and connect using the supplied credentials as an unsigned, unencrypted
803 Samba, operating as an AD DC, is sometimes operated in a domain with a
804 mix of Samba and Windows Active Directory Domain Controllers.
806 All versions of Samba from 4.0.0 to 4.3.2 inclusive, when deployed as
807 an AD DC in the same domain with Windows DCs, could be used to
808 override the protection against the MS15-096 / CVE-2015-2535 security
811 Prior to MS16-096 it was possible to bypass the quota of machine
812 accounts a non-administrative user could create. Pure Samba domains
813 are not impacted, as Samba does not implement the
814 SeMachineAccountPrivilege functionality to allow non-administrator
815 users to create new computer objects.
818 All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
819 ldb versions up to 1.1.23 inclusive) are vulnerable to
820 a remote memory read attack in the samba daemon LDAP server.
822 A malicious client can send packets that cause the LDAP server in the
823 samba daemon process to return heap memory beyond the length of the
826 This memory may contain data that the client should not be allowed to
827 see, allowing compromise of the server.
829 The memory may either be returned to the client in an error string, or
830 stored in the database by a suitabily privileged user. If untrusted
831 users can create objects in your database, please confirm that all DN
832 and name attributes are reasonable.
838 o Andrew Bartlett <abartlet@samba.org>
839 * BUG 11552: CVE-2015-8467: samdb: Match MS15-096 behaviour for
842 o Jeremy Allison <jra@samba.org>
843 * BUG 11325: CVE-2015-3223: Fix LDAP \00 search expression attack DoS.
844 * BUG 11395: CVE-2015-5252: Fix insufficient symlink verification (file
845 access outside the share).
846 * BUG 11529: CVE-2015-5299: s3-shadow-copy2: Fix missing access check on
849 o Douglas Bagnall <douglas.bagnall@catalyst.net.nz>
850 * BUG 11599: CVE-2015-5330: Fix remote read memory exploit in LDB.
852 o Stefan Metzmacher <metze@samba.org>
853 * BUG 11536: CVE-2015-5296: Add man in the middle protection when forcing
854 smb encryption on the client side.

1561 Release Notes for Samba 4.2.0
1563 =============================
1566 This is is the first stable release of Samba 4.2.
1568 Samba 4.2 will be the next version of the Samba suite.
1571 Samba User Survey 2015
1572 ======================
1574 https://www.surveygizmo.com/s3/2020369/Samba-User-Survey-2015
1576 Please take our survey. It will help us improve Samba by understanding
1577 your knowledge and needs. The survey runs until end of March 2015 and
1578 won't ask for any personal info. The full results will be shared with
1579 the Samba Team, and statistical summaries will be shared with the
1580 Samba community after the SambaXP conference (http://sambaxp.org).
1583 IMPORTANT NOTE ABOUT THE SUPPORT END OF SAMBA 3
1584 =================================================
1586 With the final release of Samba 4.2, the last series of Samba 3 has
1587 been discontinued! People still running 3.6.x or earlier,should
1588 consider moving to a more recent and maintained version (4.0 - 4.2).
1589 One of the common misconceptions is that Samba 4.x automatically
1590 means "Active Directory only": This is wrong!
1592 Acting as an Active Directory Domain Controller is just one of the
1593 enhancements included in Samba 4.0 and later. Version 4.0 was just the
1594 next release after the 3.6 series and contains all the features of the
1595 previous ones - including the NT4-style (classic) domain support. This
1596 means you can update a Samba 3.x NT4-style PDC to 4.x, just as you've
1597 updated in the past (e.g. from 3.4.x to 3.5.x). You don't have to move
1598 your NT4-style domain to an Active Directory!
1600 And of course the possibility remains unchanged, to setup a new NT4-style
1601 PDC with Samba 4.x, like done in the past (e.g. with openLDAP backend).
1602 Active Directory support in Samba 4 is additional and does not replace
1603 any of these features. We do understand the difficulty presented by
1604 existing LDAP structures and for that reason there isn't a plan to
1605 decommission the classic PDC support. It remains tested by the continuous
1608 The code that supports the classic Domain Controller is also the same
1609 code that supports the internal 'Domain' of standalone servers and
1610 Domain Member Servers. This means that we still use this code, even
1611 when not acting as an AD Domain Controller. It is also the basis for
1612 some of the features of FreeIPA and so it gets development attention
1613 from that direction as well.
1619 Read the "Winbindd/Netlogon improvements" section (below) carefully!
1625 Transparent File Compression
1626 ============================
1628 Samba 4.2.0 adds support for the manipulation of file and folder
1629 compression flags on the Btrfs filesystem.
1630 With the Btrfs Samba VFS module enabled, SMB2+ compression flags can
1631 be set remotely from the Windows Explorer File->Properties->Advanced
1632 dialog. Files flagged for compression are transparently compressed
1633 and uncompressed when accessed or modified.
1635 Previous File Versions with Snapper
1636 ===================================
1638 The newly added Snapper VFS module exposes snapshots managed by
1639 Snapper for use by Samba. This provides the ability for remote
1640 clients to access shadow-copies via Windows Explorer using the
1641 "previous versions" dialog.
1643 Winbindd/Netlogon improvements
1644 ==============================
1646 The whole concept of maintaining the netlogon secure channel
1647 to (other) domain controllers was rewritten in order to maintain
1648 global state in a netlogon_creds_cli.tdb. This is the proper fix
1649 for a large number of bugs:
1651 https://bugzilla.samba.org/show_bug.cgi?id=6563
1652 https://bugzilla.samba.org/show_bug.cgi?id=7944
1653 https://bugzilla.samba.org/show_bug.cgi?id=7945
1654 https://bugzilla.samba.org/show_bug.cgi?id=7568
1655 https://bugzilla.samba.org/show_bug.cgi?id=8599
1657 In addition a strong session key is now required by default,
1658 which means that communication to older servers or clients
1659 might be rejected by default.
1661 For the client side we have the following new options:
1662 "require strong key" (yes by default), "reject md5 servers" (no by default).
1663 E.g. for Samba 3.0.37 you need "require strong key = no" and
1664 for NT4 DCs you need "require strong key = no" and "client NTLMv2 auth = no",
1666 On the server side (as domain controller) we have the following new options:
1667 "allow nt4 crypto" (no by default), "reject md5 client" (no by default).
1668 E.g. in order to allow Samba < 3.0.27 or NT4 members to work
1669 you need "allow nt4 crypto = yes"
1671 winbindd does not list group memberships for display purposes
1672 (e.g. getent group <domain\<group>) anymore by default.
1673 The new default is "winbind expand groups = 0" now,
1674 the reason for this is the same as for "winbind enum users = no"
1675 and "winbind enum groups = no". Providing this information is not always
1676 reliably possible, e.g. if there are trusted domains.
1678 Please consult the smb.conf manpage for more details on these new options.
1680 Winbindd use on the Samba AD DC
1681 ===============================
1683 Winbindd is now used on the Samba AD DC by default, replacing the
1684 partial rewrite used for winbind operations in Samba 4.0 and 4.1.
1686 This allows more code to be shared, more options to be honoured, and
1687 paves the way for support for trusted domains in the AD DC.
1689 If required the old internal winbind can be activated by setting
1690 'server services = +winbind -winbindd'. Upgrading users with a server
1691 services parameter specified should ensure they change 'winbind' to
1692 'winbindd' to obtain the new functionality.
1694 The 'samba' binary still manages the starting of this service, there
1695 is no need to start the winbindd binary manually.
1697 Winbind now requires secured connections
1698 ========================================
1700 To improve protection against rogue domain controllers we now require
1701 that when we connect to an AD DC in our forest, that the connection be
1702 signed using SMB Signing. Set 'client signing = off' in the smb.conf
1705 Also and DCE/RPC pipes must be sealed, set 'require strong key =
1706 false' and 'winbind sealed pipes = false' to disable.
1708 Finally, the default for 'client ldap sasl wrapping' has been set to
1709 'sign', to ensure the integrity of LDAP connections. Set 'client ldap
1710 sasl wrapping = plain' to disable.
1712 Larger IO sizes for SMB2/3 by default
1713 =====================================
1715 The default values for "smb2 max read", "smb2 max write" and "smb2 max trans"
1716 have been changed to 8388608 (8MiB) in order to match the default of
1722 The SMB2 protocol allows clients to aggressively cache files
1723 locally above and beyond the caching allowed by SMB1 and SMB2 oplocks.
1725 Called SMB2 leases, this can greatly reduce traffic on an SMB2
1726 connection. Samba 4.2 now implements SMB2 leases.
1728 It can be turned on by setting the parameter "smb2 leases = yes"
1729 in the [global] section of your smb.conf. This parameter is set
1730 to off by default until the SMB2 leasing code is declared fully stable.
1732 Improved DCERPC man in the middle detection
1733 ===========================================
1735 The DCERPC header signing has been implemented
1736 in addition to the dcerpc_sec_verification_trailer
1739 Overhauled "net idmap" command
1740 ==============================
1742 The command line interface of the "net idmap" command has been
1743 made systematic, and subcommands for reading and writing the autorid idmap
1744 database have been added. Note that the writing commands should be
1745 used with great care. See the net(8) manual page for details.
1750 The tdb library, our core mechanism to store Samba-specific data on disk and
1751 share it between processes, has been improved to support process shared robust
1752 mutexes on Linux. These mutexes are available on Linux and Solaris and
1753 significantly reduce the overhead involved with tdb. To enable mutexes for
1756 dbwrap_tdb_mutexes:* = yes
1758 in the [global] section of your smb.conf.
1760 Tdb file space management has also been made more efficient. This
1761 will lead to smaller and less fragmented databases.
1763 Messaging improvements
1764 ======================
1766 Our internal messaging subsystem, used for example for things like oplock
1767 break messages between smbds or setting a process debug level dynamically, has
1768 been rewritten to use unix domain datagram messages.
1773 Samba's file server clustering component CTDB is now integrated in the
1774 Samba tree. This avoids the confusion of compatibility of Samba and CTDB
1775 versions as existed previously.
1777 To build the Samba file server with cluster support, use the configure
1778 command line option --with-cluster-support. This will build clustered
1779 file server against the in-tree CTDB and will also build CTDB.
1780 Building clustered samba with previous versions of CTDB is no longer
1783 Samba Registry Editor
1784 =====================
1786 The utitlity to browse the samba registry has been overhauled by our Google
1787 Summer of Code student Chris Davis. Now samba-regedit has a
1788 Midnight-Commander-like theme and UI experience. You can browse keys and edit
1789 the diffent value types. For a data value type a hexeditor has been
1792 Bad Password Lockout in the AD DC
1793 =================================
1795 Samba's AD DC now implements bad password lockout (on a per-DC basis).
1797 That is, incorrect password attempts are tracked, and accounts locked
1798 out if too many bad passwords are submitted. There is also a grace
1799 period of 60 minutes on the previous password when used for NTLM
1800 authentication (matching Windows 2003 SP1: https://support2.microsoft.com/kb/906305).
1802 The relevant settings can be seen using 'samba-tool domain
1803 passwordsettings show' (the new settings being highlighted):
1805 Password informations for domain 'DC=samba,DC=example,DC=com'
1807 Password complexity: on
1808 Store plaintext passwords: off
1809 Password history length: 24
1810 Minimum password length: 7
1811 Minimum password age (days): 1
1812 Maximum password age (days): 42
1813 * Account lockout duration (mins): 30 *
1814 * Account lockout threshold (attempts): 0 *
1815 * Reset account lockout after (mins): 30 *
1817 These values can be set using 'samba-tool domain passwordsettings set'.
1819 Correct defaults in the smb.conf manpages
1820 =========================================
1822 The default values for smb.conf parameters are now correctly specified
1823 in the smb.conf manpage, even when they refer to build-time specified
1824 paths. Provided Samba is built on a system with the right tools
1825 (xsltproc in particular) required to generate our man pages, then
1826 these will be built with the exact same embedded paths as used by the
1827 configuration parser at runtime. Additionally, the default values
1828 read from the smb.conf manpage are checked by our test suite to match
1829 the values seen in testparm and used by the running binaries.
1831 Consistent behaviour between samba-tool testparm and testparm
1832 =============================================================
1834 With the exception of the registry backend, which remains only
1835 available in the file server, the behaviour of the smb.conf parser and
1836 the tools 'samba-tool testparm' and 'testparm' is now consistent,
1837 particularly with regard to default values. Except with regard to
1838 registry shares, it is no longer needed to use one tool on the AD
1839 DC, and another on the file server.
1844 A VFS module for basic WORM (Write once read many) support has been
1845 added. It allows an additional layer on top of a Samba share, that provides
1846 a basic set of WORM functionality on the client side, to control the
1847 writeability of files and folders.
1849 As the module is simply an additional layer, share access and permissions
1850 work like expected - only WORM functionality is added on top. Removing the
1851 module from the share configuration, removes this layer again. The
1852 filesystem ACLs are not affected in any way from the module and treated
1855 The module does not provide complete WORM functions, like some archiving
1856 products do! It is not audit-proof, because the WORM function is only
1857 available on the client side, when accessing a share through SMB! If
1858 the same folder is shared by other services like NFS, the access only
1859 depends on the underlying filesystem ACLs. Equally if you access the
1860 content directly on the server.
1862 For additional information, see
1863 https://wiki.samba.org/index.php/VFS/vfs_worm
1865 vfs_fruit, a VFS module for OS X clients
1866 ========================================
1868 A new VFS module that provides enhanced compatibility with Apple SMB
1869 clients and interoperability with a Netatalk 3 AFP fileserver.
1871 The module features enhanced performance with reliable named streams
1872 support, interoperability with special characters commonly used by OS
1873 X client (eg '*', '/'), integrated file locking and Mac metadata
1874 access with Netatalk 3 and enhanced performance by implementing
1875 Apple's SMB2 extension codenamed "AAPL".
1877 The modules behaviour is fully configurable, please refer to the
1878 manpage vfs_fruit for further details.
1880 smbclient archival improvements
1881 ===============================
1883 Archive creation and extraction support in smbclient has been rewritten
1884 to use libarchive. This fixes a number of outstanding bugs in Samba's
1885 previous custom tar implementation and also adds support for the
1886 extraction of zipped archives.
1887 smbclient archive support can be enabled or disabled at build time with
1888 corresponding --with[out]-libarchive configure parameters.
