141 Release Notes for Samba 4.2.10
143 ==============================
146 This is a security release in order to address the following CVEs:
148 o CVE-2015-5370 (Multiple errors in DCE-RPC code)
150 o CVE-2016-2110 (Man in the middle attacks possible with NTLMSSP)
152 o CVE-2016-2111 (NETLOGON Spoofing Vulnerability)
154 o CVE-2016-2112 (LDAP client and server don't enforce integrity)
156 o CVE-2016-2113 (Missing TLS certificate validation)
158 o CVE-2016-2114 ("server signing = mandatory" not enforced)
160 o CVE-2016-2115 (SMB IPC traffic is not integrity protected)
162 o CVE-2016-2118 (SAMR and LSA man in the middle attacks possible)
164 The number of changes are rather huge for a security release,
165 compared to typical security releases.
167 Given the number of problems and the fact that they are all related
168 to man in the middle attacks we decided to fix them all at once
169 instead of splitting them.
171 In order to prevent the man in the middle attacks it was required
172 to change the (default) behavior for some protocols. Please see the
173 "New smb.conf options" and "Behavior changes" sections below.
181 Versions of Samba from 3.6.0 to 4.4.0 inclusive are vulnerable to
182 denial of service attacks (crashes and high cpu consumption)
183 in the DCE-RPC client and server implementations. In addition,
184 errors in validation of the DCE-RPC packets can lead to a downgrade
185 of a secure connection to an insecure one.
187 While we think it is unlikely, there's a nonzero chance for
188 a remote code execution attack against the client components,
189 which are used by smbd, winbindd and tools like net, rpcclient and
190 others. This may gain root access to the attacker.
192 The above applies all possible server roles Samba can operate in.
194 Note that versions before 3.6.0 had completely different marshalling
195 functions for the generic DCE-RPC layer. It's quite possible that
196 that code has similar problems!
198 The downgrade of a secure connection to an insecure one may
199 allow an attacker to take control of Active Directory object
200 handles created on a connection created from an Administrator
201 account and re-use them on the now non-privileged connection,
202 compromising the security of the Samba AD-DC.
206 There are several man in the middle attacks possible with
207 NTLMSSP authentication.
209 E.g. NTLMSSP_NEGOTIATE_SIGN and NTLMSSP_NEGOTIATE_SEAL
210 can be cleared by a man in the middle.
212 This was by protocol design in earlier Windows versions.
214 Windows Server 2003 RTM and Vista RTM introduced a way
215 to protect against the trivial downgrade.
217 See MsvAvFlags and flag 0x00000002 in
218 https://msdn.microsoft.com/en-us/library/cc236646.aspx
220 This new feature also implies support for a mechlistMIC
221 when used within SPNEGO, which may prevent downgrades
222 from other SPNEGO mechs, e.g. Kerberos, if sign or
223 seal is finally negotiated.
225 The Samba implementation doesn't enforce the existence of
226 required flags, which were requested by the application layer,
227 e.g. LDAP or SMB1 encryption (via the unix extensions).
228 As a result a man in the middle can take over the connection.
229 It is also possible to misguide client and/or
230 server to send unencrypted traffic even if encryption
231 was explicitly requested.
233 LDAP (with NTLMSSP authentication) is used as a client
234 by various admin tools of the Samba project,
235 e.g. "net", "samba-tool", "ldbsearch", "ldbedit", ...
237 As an active directory member server LDAP is also used
238 by the winbindd service when connecting to domain controllers.
240 Samba also offers an LDAP server when running as
241 active directory domain controller.
243 The NTLMSSP authentication used by the SMB1 encryption
244 is protected by smb signing, see CVE-2015-5296.
248 It's basically the same as CVE-2015-0005 for Windows:
250 The NETLOGON service in Microsoft Windows Server 2003 SP2,
251 Windows Server 2008 SP2 and R2 SP1, and Windows Server 2012 Gold
252 and R2, when a Domain Controller is configured, allows remote
253 attackers to spoof the computer name of a secure channel's
254 endpoint, and obtain sensitive session information, by running a
255 crafted application and leveraging the ability to sniff network
256 traffic, aka "NETLOGON Spoofing Vulnerability".
258 The vulnerability in Samba is worse as it doesn't require
259 credentials of a computer account in the domain.
261 This only applies to Samba running as classic primary domain controller,
262 classic backup domain controller or active directory domain controller.
264 The security patches introduce a new option called "raw NTLMv2 auth"
265 ("yes" or "no") for the [global] section in smb.conf.
266 Samba (the smbd process) will reject client using raw NTLMv2
267 without using NTLMSSP.
269 Note that this option also applies to Samba running as
270 standalone server and member server.
272 You should also consider using "lanman auth = no" (which is already the default)
273 and "ntlm auth = no". Have a look at the smb.conf manpage for further details,
274 as they might impact compatibility with older clients. These also
275 apply for all server roles.
279 Samba uses various LDAP client libraries, a builtin one and/or the system
280 ldap libraries (typically openldap).
282 As active directory domain controller Samba also provides an LDAP server.
284 Samba takes care of doing SASL (GSS-SPNEGO) authentication with Kerberos or NTLMSSP
285 for LDAP connections, including possible integrity (sign) and privacy (seal)
288 Samba has support for an option called "client ldap sasl wrapping" since version
289 3.2.0. Its default value has changed from "plain" to "sign" with version 4.2.0.
291 Tools using the builtin LDAP client library do not obey the
292 "client ldap sasl wrapping" option. This applies to tools like:
293 "samba-tool", "ldbsearch", "ldbedit" and more. Some of them have command line
294 options like "--sign" and "--encrypt". With the security update they will
295 also obey the "client ldap sasl wrapping" option as default.
297 In all cases, even if explicitly request via "client ldap sasl wrapping",
298 "--sign" or "--encrypt", the protection can be downgraded by a man in the
301 The LDAP server doesn't have an option to enforce strong authentication
302 yet. The security patches will introduce a new option called
303 "ldap server require strong auth", possible values are "no",
304 "allow_sasl_over_tls" and "yes".
306 As the default behavior was as "no" before, you may
307 have to explicitly change this option until all clients have
308 been adjusted to handle LDAP_STRONG_AUTH_REQUIRED errors.
309 Windows clients and Samba member servers already use
310 integrity protection.
314 Samba has support for TLS/SSL for some protocols:
315 ldap and http, but currently certificates are not
316 validated at all. While we have a "tls cafile" option,
317 the configured certificate is not used to validate
318 the server certificate.
320 This applies to ldaps:// connections triggered by tools like:
321 "ldbsearch", "ldbedit" and more. Note that it only applies
322 to the ldb tools when they are built as part of Samba or with Samba
323 extensions installed, which means the Samba builtin LDAP client library is
326 It also applies to dcerpc client connections using ncacn_http (with https://),
327 which are only used by the openchange project. Support for ncacn_http
328 was introduced in version 4.2.0.
330 The security patches will introduce a new option called
331 "tls verify peer". Possible values are "no_check", "ca_only",
332 "ca_and_name_if_available", "ca_and_name" and "as_strict_as_possible".
334 If you use the self-signed certificates which are auto-generated
335 by Samba, you won't have a crl file and need to explicitly
336 set "tls verify peer = ca_and_name".
340 Due to a regression introduced in Samba 4.0.0,
341 an explicit "server signing = mandatory" in the [global] section
342 of the smb.conf was not enforced for clients using the SMB1 protocol.
344 As a result it does not enforce smb signing and allows man in the middle attacks.
346 This problem applies to all possible server roles:
347 standalone server, member server, classic primary domain controller,
348 classic backup domain controller and active directory domain controller.
350 In addition, when Samba is configured with "server role = active directory domain controller"
351 the effective default for the "server signing" option should be "mandatory".
353 During the early development of Samba 4 we had a new experimental
354 file server located under source4/smb_server. But before
355 the final 4.0.0 release we switched back to the file server
358 But the logic for the correct default of "server signing" was not
359 ported correctly ported.
361 Note that the default for server roles other than active directory domain
362 controller, is "off" because of performance reasons.
366 Samba has an option called "client signing", this is turned off by default
367 for performance reasons on file transfers.
369 This option is also used when using DCERPC with ncacn_np.
371 In order to get integrity protection for ipc related communication
372 by default the "client ipc signing" option is introduced.
373 The effective default for this new option is "mandatory".
375 In order to be compatible with more SMB server implementations,
376 the following additional options are introduced:
377 "client ipc min protocol" ("NT1" by default) and
378 "client ipc max protocol" (the highest support SMB2/3 dialect by default).
379 These options overwrite the "client min protocol" and "client max protocol"
380 options, because the default for "client max protocol" is still "NT1".
381 The reason for this is the fact that all SMB2/3 support SMB signing,
382 while there are still SMB1 implementations which don't offer SMB signing
383 by default (this includes Samba versions before 4.0.0).
385 Note that winbindd (in versions 4.2.0 and higher) enforces SMB signing
386 against active directory domain controllers despite of the
387 "client signing" and "client ipc signing" options.
389 o CVE-2016-2118 (a.k.a. BADLOCK):
391 The Security Account Manager Remote Protocol [MS-SAMR] and the
392 Local Security Authority (Domain Policy) Remote Protocol [MS-LSAD]
393 are both vulnerable to man in the middle attacks. Both are application level
394 protocols based on the generic DCE 1.1 Remote Procedure Call (DCERPC) protocol.
396 These protocols are typically available on all Windows installations
397 as well as every Samba server. They are used to maintain
398 the Security Account Manager Database. This applies to all
399 roles, e.g. standalone, domain member, domain controller.
401 Any authenticated DCERPC connection a client initiates against a server
402 can be used by a man in the middle to impersonate the authenticated user
403 against the SAMR or LSAD service on the server.
405 The client chosen application protocol, auth type (e.g. Kerberos or NTLMSSP)
406 and auth level (NONE, CONNECT, PKT_INTEGRITY, PKT_PRIVACY) do not matter
407 in this case. A man in the middle can change auth level to CONNECT
408 (which means authentication without message protection) and take over
411 As a result, a man in the middle is able to get read/write access to the
412 Security Account Manager Database, which reveals all passwords
413 and any other potential sensitive information.
415 Samba running as an active directory domain controller is additionally
416 missing checks to enforce PKT_PRIVACY for the
417 Directory Replication Service Remote Protocol [MS-DRSR] (drsuapi)
418 and the BackupKey Remote Protocol [MS-BKRP] (backupkey).
419 The Domain Name Service Server Management Protocol [MS-DNSP] (dnsserver)
420 is not enforcing at least PKT_INTEGRITY.
426 allow dcerpc auth level connect (G)
428 This option controls whether DCERPC services are allowed to be used with
429 DCERPC_AUTH_LEVEL_CONNECT, which provides authentication, but no per
430 message integrity nor privacy protection.
432 Some interfaces like samr, lsarpc and netlogon have a hard-coded default
433 of no and epmapper, mgmt and rpcecho have a hard-coded default of yes.
435 The behavior can be overwritten per interface name (e.g. lsarpc,
436 netlogon, samr, srvsvc, winreg, wkssvc ...) by using
437 'allow dcerpc auth level connect:interface = yes' as option.
439 This option yields precedence to the implementation specific restrictions.
440 E.g. the drsuapi and backupkey protocols require DCERPC_AUTH_LEVEL_PRIVACY.
441 The dnsserver protocol requires DCERPC_AUTH_LEVEL_INTEGRITY.
443 Default: allow dcerpc auth level connect = no
445 Example: allow dcerpc auth level connect = yes
447 client ipc signing (G)
449 This controls whether the client is allowed or required to use
450 SMB signing for IPC$ connections as DCERPC transport. Possible
451 values are auto, mandatory and disabled.
453 When set to mandatory or default, SMB signing is required.
455 When set to auto, SMB signing is offered, but not enforced and
456 if set to disabled, SMB signing is not offered either.
458 Connections from winbindd to Active Directory Domain Controllers
459 always enforce signing.
461 Default: client ipc signing = default
463 client ipc max protocol (G)
465 The value of the parameter (a string) is the highest protocol level that will
466 be supported for IPC$ connections as DCERPC transport.
468 Normally this option should not be set as the automatic negotiation phase
469 in the SMB protocol takes care of choosing the appropriate protocol.
471 The value default refers to the latest supported protocol, currently SMB3_11.
473 See client max protocol for a full list of available protocols.
474 The values CORE, COREPLUS, LANMAN1, LANMAN2 are silently upgraded to NT1.
476 Default: client ipc max protocol = default
478 Example: client ipc max protocol = SMB2_10
480 client ipc min protocol (G)
482 This setting controls the minimum protocol version that the will be
483 attempted to use for IPC$ connections as DCERPC transport.
485 Normally this option should not be set as the automatic negotiation phase
486 in the SMB protocol takes care of choosing the appropriate protocol.
488 The value default refers to the higher value of NT1 and the
489 effective value of "client min protocol".
491 See client max protocol for a full list of available protocols.
492 The values CORE, COREPLUS, LANMAN1, LANMAN2 are silently upgraded to NT1.
494 Default: client ipc min protocol = default
496 Example: client ipc min protocol = SMB3_11
498 ldap server require strong auth (G)
500 The ldap server require strong auth defines whether the
501 ldap server requires ldap traffic to be signed or
502 signed and encrypted (sealed). Possible values are no,
503 allow_sasl_over_tls and yes.
505 A value of no allows simple and sasl binds over all transports.
507 A value of allow_sasl_over_tls allows simple and sasl binds (without sign or seal)
508 over TLS encrypted connections. Unencrypted connections only
509 allow sasl binds with sign or seal.
511 A value of yes allows only simple binds over TLS encrypted connections.
512 Unencrypted connections only allow sasl binds with sign or seal.
514 Default: ldap server require strong auth = yes
518 This parameter determines whether or not smbd(8) will allow SMB1 clients
519 without extended security (without SPNEGO) to use NTLMv2 authentication.
521 If this option, lanman auth and ntlm auth are all disabled, then only
522 clients with SPNEGO support will be permitted. That means NTLMv2 is only
523 supported within NTLMSSP.
525 Default: raw NTLMv2 auth = no
529 This controls if and how strict the client will verify the peer's
530 certificate and name. Possible values are (in increasing order): no_check,
531 ca_only, ca_and_name_if_available, ca_and_name and as_strict_as_possible.
533 When set to no_check the certificate is not verified at all,
534 which allows trivial man in the middle attacks.
536 When set to ca_only the certificate is verified to be signed from a ca
537 specified in the "tls ca file" option. Setting "tls ca file" to a valid file
538 is required. The certificate lifetime is also verified. If the "tls crl file"
539 option is configured, the certificate is also verified against
542 When set to ca_and_name_if_available all checks from ca_only are performed.
543 In addition, the peer hostname is verified against the certificate's
544 name, if it is provided by the application layer and not given as
545 an ip address string.
547 When set to ca_and_name all checks from ca_and_name_if_available are performed.
548 In addition the peer hostname needs to be provided and even an ip
549 address is checked against the certificate's name.
551 When set to as_strict_as_possible all checks from ca_and_name are performed.
552 In addition the "tls crl file" needs to be configured. Future versions
553 of Samba may implement additional checks.
555 Default: tls verify peer = as_strict_as_possible
557 tls priority (G) (backported from Samba 4.3 to Samba 4.2)
559 This option can be set to a string describing the TLS protocols to be
560 supported in the parts of Samba that use GnuTLS, specifically the AD DC.
562 The default turns off SSLv3, as this protocol is no longer considered
563 secure after CVE-2014-3566 (otherwise known as POODLE) impacted SSLv3 use
564 in HTTPS applications.
566 The valid options are described in the GNUTLS Priority-Strings
567 documentation at http://gnutls.org/manual/html_node/Priority-Strings.html
569 Default: tls priority = NORMAL:-VERS-SSL3.0
575 o The default auth level for authenticated binds has changed from
576 DCERPC_AUTH_LEVEL_CONNECT to DCERPC_AUTH_LEVEL_INTEGRITY.
577 That means ncacn_ip_tcp:server is now implicitly the same
578 as ncacn_ip_tcp:server[sign] and offers a similar protection
579 as ncacn_np:server, which relies on smb signing.
581 o The following constraints are applied to SMB1 connections:
583 - "client lanman auth = yes" is now consistently
584 required for authenticated connections using the
585 SMB1 LANMAN2 dialect.
586 - "client ntlmv2 auth = yes" and "client use spnego = yes"
587 (both the default values), require extended security (SPNEGO)
588 support from the server. That means NTLMv2 is only used within
591 o Tools like "samba-tool", "ldbsearch", "ldbedit" and more obey the
592 default of "client ldap sasl wrapping = sign". Even with
593 "client ldap sasl wrapping = plain" they will automatically upgrade
594 to "sign" when getting LDAP_STRONG_AUTH_REQUIRED from the LDAP

692 Release Notes for Samba 4.2.9
694 =============================
697 This is a security release in order to address the following CVEs:
699 o CVE-2015-7560 (Incorrect ACL get/set allowed on symlink path)
700 o CVE-2016-0771 (Out-of-bounds read in internal DNS server)
707 All versions of Samba from 3.2.0 to 4.4.0rc3 inclusive are vulnerable to
708 a malicious client overwriting the ownership of ACLs using symlinks.
710 An authenticated malicious client can use SMB1 UNIX extensions to
711 create a symlink to a file or directory, and then use non-UNIX SMB1
712 calls to overwrite the contents of the ACL on the file or directory
716 All versions of Samba from 4.0.0 to 4.4.0rc3 inclusive, when deployed as
717 an AD DC and choose to run the internal DNS server, are vulnerable to an
718 out-of-bounds read issue during DNS TXT record handling caused by users
719 with permission to modify DNS records.
721 A malicious client can upload a specially constructed DNS TXT record,
722 resulting in a remote denial-of-service attack. As long as the affected
723 TXT record remains undisturbed in the Samba database, a targeted DNS
724 query may continue to trigger this exploit.
726 While unlikely, the out-of-bounds read may bypass safety checks and
727 allow leakage of memory from the server in the form of a DNS TXT reply.
729 By default only authenticated accounts can upload DNS records,
730 as "allow dns updates = secure only" is the default.
731 Any other value would allow anonymous clients to trigger this
732 bug, which is a much higher risk.

847 Release Notes for Samba 4.2.7
849 =============================
852 This is a security release in order to address the following CVEs:
854 o CVE-2015-3223 (Denial of service in Samba Active Directory
856 o CVE-2015-5252 (Insufficient symlink verification in smbd)
857 o CVE-2015-5299 (Missing access control check in shadow copy
859 o CVE-2015-5296 (Samba client requesting encryption vulnerable
861 o CVE-2015-8467 (Denial of service attack against Windows
862 Active Directory server)
863 o CVE-2015-5330 (Remote memory read in Samba LDAP server)
865 Please note that if building against a system libldb, the required
866 version has been bumped to ldb-1.1.24. This is needed to ensure
867 we build against a system ldb library that contains the fixes
868 for CVE-2015-5330 and CVE-2015-3223.
875 All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
876 ldb versions up to 1.1.23 inclusive) are vulnerable to
877 a denial of service attack in the samba daemon LDAP server.
879 A malicious client can send packets that cause the LDAP server in the
880 samba daemon process to become unresponsive, preventing the server
881 from servicing any other requests.
883 This flaw is not exploitable beyond causing the code to loop expending
887 All versions of Samba from 3.0.0 to 4.3.2 inclusive are vulnerable to
888 a bug in symlink verification, which under certain circumstances could
889 allow client access to files outside the exported share path.
891 If a Samba share is configured with a path that shares a common path
892 prefix with another directory on the file system, the smbd daemon may
893 allow the client to follow a symlink pointing to a file or directory
894 in that other directory, even if the share parameter "wide links" is
895 set to "no" (the default).
898 All versions of Samba from 3.2.0 to 4.3.2 inclusive are vulnerable to
899 a missing access control check in the vfs_shadow_copy2 module. When
900 looking for the shadow copy directory under the share path the current
901 accessing user should have DIRECTORY_LIST access rights in order to
902 view the current snapshots.
904 This was not being checked in the affected versions of Samba.
907 Versions of Samba from 3.2.0 to 4.3.2 inclusive do not ensure that
908 signing is negotiated when creating an encrypted client connection to
911 Without this a man-in-the-middle attack could downgrade the connection
912 and connect using the supplied credentials as an unsigned, unencrypted
916 Samba, operating as an AD DC, is sometimes operated in a domain with a
917 mix of Samba and Windows Active Directory Domain Controllers.
919 All versions of Samba from 4.0.0 to 4.3.2 inclusive, when deployed as
920 an AD DC in the same domain with Windows DCs, could be used to
921 override the protection against the MS15-096 / CVE-2015-2535 security
924 Prior to MS16-096 it was possible to bypass the quota of machine
925 accounts a non-administrative user could create. Pure Samba domains
926 are not impacted, as Samba does not implement the
927 SeMachineAccountPrivilege functionality to allow non-administrator
928 users to create new computer objects.
931 All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
932 ldb versions up to 1.1.23 inclusive) are vulnerable to
933 a remote memory read attack in the samba daemon LDAP server.
935 A malicious client can send packets that cause the LDAP server in the
936 samba daemon process to return heap memory beyond the length of the
939 This memory may contain data that the client should not be allowed to
940 see, allowing compromise of the server.
942 The memory may either be returned to the client in an error string, or
943 stored in the database by a suitabily privileged user. If untrusted
944 users can create objects in your database, please confirm that all DN
945 and name attributes are reasonable.
951 o Andrew Bartlett <abartlet@samba.org>
952 * BUG 11552: CVE-2015-8467: samdb: Match MS15-096 behaviour for
955 o Jeremy Allison <jra@samba.org>
956 * BUG 11325: CVE-2015-3223: Fix LDAP \00 search expression attack DoS.
957 * BUG 11395: CVE-2015-5252: Fix insufficient symlink verification (file
958 access outside the share).
959 * BUG 11529: CVE-2015-5299: s3-shadow-copy2: Fix missing access check on
962 o Douglas Bagnall <douglas.bagnall@catalyst.net.nz>
963 * BUG 11599: CVE-2015-5330: Fix remote read memory exploit in LDB.
965 o Stefan Metzmacher <metze@samba.org>

1674 Release Notes for Samba 4.2.0
1676 =============================
1679 This is is the first stable release of Samba 4.2.
1681 Samba 4.2 will be the next version of the Samba suite.
1684 Samba User Survey 2015

1689 Please take our survey. It will help us improve Samba by understanding
1690 your knowledge and needs. The survey runs until end of March 2015 and
1691 won't ask for any personal info. The full results will be shared with
1692 the Samba Team, and statistical summaries will be shared with the
1693 Samba community after the SambaXP conference (http://sambaxp.org).
1696 IMPORTANT NOTE ABOUT THE SUPPORT END OF SAMBA 3
1697 =================================================
1699 With the final release of Samba 4.2, the last series of Samba 3 has
1700 been discontinued! People still running 3.6.x or earlier,should
1701 consider moving to a more recent and maintained version (4.0 - 4.2).
1702 One of the common misconceptions is that Samba 4.x automatically
1703 means "Active Directory only": This is wrong!
1705 Acting as an Active Directory Domain Controller is just one of the
1706 enhancements included in Samba 4.0 and later. Version 4.0 was just the
1707 next release after the 3.6 series and contains all the features of the
1708 previous ones - including the NT4-style (classic) domain support. This
1709 means you can update a Samba 3.x NT4-style PDC to 4.x, just as you've
1710 updated in the past (e.g. from 3.4.x to 3.5.x). You don't have to move
1711 your NT4-style domain to an Active Directory!
1713 And of course the possibility remains unchanged, to setup a new NT4-style
1714 PDC with Samba 4.x, like done in the past (e.g. with openLDAP backend).
1715 Active Directory support in Samba 4 is additional and does not replace
1716 any of these features. We do understand the difficulty presented by
1717 existing LDAP structures and for that reason there isn't a plan to
1718 decommission the classic PDC support. It remains tested by the continuous
1721 The code that supports the classic Domain Controller is also the same
1722 code that supports the internal 'Domain' of standalone servers and
1723 Domain Member Servers. This means that we still use this code, even
1724 when not acting as an AD Domain Controller. It is also the basis for
1725 some of the features of FreeIPA and so it gets development attention
1726 from that direction as well.
1732 Read the "Winbindd/Netlogon improvements" section (below) carefully!
1738 Transparent File Compression
1739 ============================
1741 Samba 4.2.0 adds support for the manipulation of file and folder
1742 compression flags on the Btrfs filesystem.
1743 With the Btrfs Samba VFS module enabled, SMB2+ compression flags can
1744 be set remotely from the Windows Explorer File->Properties->Advanced
1745 dialog. Files flagged for compression are transparently compressed
1746 and uncompressed when accessed or modified.
1748 Previous File Versions with Snapper
1749 ===================================
1751 The newly added Snapper VFS module exposes snapshots managed by
1752 Snapper for use by Samba. This provides the ability for remote
1753 clients to access shadow-copies via Windows Explorer using the
1754 "previous versions" dialog.
1756 Winbindd/Netlogon improvements
1757 ==============================
1759 The whole concept of maintaining the netlogon secure channel
1760 to (other) domain controllers was rewritten in order to maintain
1761 global state in a netlogon_creds_cli.tdb. This is the proper fix
1762 for a large number of bugs:
1764 https://bugzilla.samba.org/show_bug.cgi?id=6563
1765 https://bugzilla.samba.org/show_bug.cgi?id=7944
1766 https://bugzilla.samba.org/show_bug.cgi?id=7945
1767 https://bugzilla.samba.org/show_bug.cgi?id=7568
1768 https://bugzilla.samba.org/show_bug.cgi?id=8599
1770 In addition a strong session key is now required by default,
1771 which means that communication to older servers or clients
1772 might be rejected by default.
1774 For the client side we have the following new options:
1775 "require strong key" (yes by default), "reject md5 servers" (no by default).
1776 E.g. for Samba 3.0.37 you need "require strong key = no" and
1777 for NT4 DCs you need "require strong key = no" and "client NTLMv2 auth = no",
1779 On the server side (as domain controller) we have the following new options:
1780 "allow nt4 crypto" (no by default), "reject md5 client" (no by default).
1781 E.g. in order to allow Samba < 3.0.27 or NT4 members to work
1782 you need "allow nt4 crypto = yes"
1784 winbindd does not list group memberships for display purposes
1785 (e.g. getent group <domain\<group>) anymore by default.
1786 The new default is "winbind expand groups = 0" now,
1787 the reason for this is the same as for "winbind enum users = no"
1788 and "winbind enum groups = no". Providing this information is not always
1789 reliably possible, e.g. if there are trusted domains.
1791 Please consult the smb.conf manpage for more details on these new options.
1793 Winbindd use on the Samba AD DC
1794 ===============================
1796 Winbindd is now used on the Samba AD DC by default, replacing the
1797 partial rewrite used for winbind operations in Samba 4.0 and 4.1.
1799 This allows more code to be shared, more options to be honoured, and
1800 paves the way for support for trusted domains in the AD DC.
1802 If required the old internal winbind can be activated by setting
1803 'server services = +winbind -winbindd'. Upgrading users with a server
1804 services parameter specified should ensure they change 'winbind' to
1805 'winbindd' to obtain the new functionality.
1807 The 'samba' binary still manages the starting of this service, there
1808 is no need to start the winbindd binary manually.
1810 Winbind now requires secured connections
1811 ========================================
1813 To improve protection against rogue domain controllers we now require
1814 that when we connect to an AD DC in our forest, that the connection be
1815 signed using SMB Signing. Set 'client signing = off' in the smb.conf
1818 Also and DCE/RPC pipes must be sealed, set 'require strong key =
1819 false' and 'winbind sealed pipes = false' to disable.
1821 Finally, the default for 'client ldap sasl wrapping' has been set to
1822 'sign', to ensure the integrity of LDAP connections. Set 'client ldap
1823 sasl wrapping = plain' to disable.
1825 Larger IO sizes for SMB2/3 by default
1826 =====================================
1828 The default values for "smb2 max read", "smb2 max write" and "smb2 max trans"
1829 have been changed to 8388608 (8MiB) in order to match the default of
1835 The SMB2 protocol allows clients to aggressively cache files
1836 locally above and beyond the caching allowed by SMB1 and SMB2 oplocks.
1838 Called SMB2 leases, this can greatly reduce traffic on an SMB2
1839 connection. Samba 4.2 now implements SMB2 leases.
1841 It can be turned on by setting the parameter "smb2 leases = yes"
1842 in the [global] section of your smb.conf. This parameter is set
1843 to off by default until the SMB2 leasing code is declared fully stable.
1845 Improved DCERPC man in the middle detection
1846 ===========================================
1848 The DCERPC header signing has been implemented
1849 in addition to the dcerpc_sec_verification_trailer
1852 Overhauled "net idmap" command
1853 ==============================
1855 The command line interface of the "net idmap" command has been
1856 made systematic, and subcommands for reading and writing the autorid idmap
1857 database have been added. Note that the writing commands should be
1858 used with great care. See the net(8) manual page for details.
1863 The tdb library, our core mechanism to store Samba-specific data on disk and
1864 share it between processes, has been improved to support process shared robust
1865 mutexes on Linux. These mutexes are available on Linux and Solaris and
1866 significantly reduce the overhead involved with tdb. To enable mutexes for
1869 dbwrap_tdb_mutexes:* = yes
1871 in the [global] section of your smb.conf.
1873 Tdb file space management has also been made more efficient. This
1874 will lead to smaller and less fragmented databases.
1876 Messaging improvements
1877 ======================
1879 Our internal messaging subsystem, used for example for things like oplock
1880 break messages between smbds or setting a process debug level dynamically, has
1881 been rewritten to use unix domain datagram messages.
1886 Samba's file server clustering component CTDB is now integrated in the
1887 Samba tree. This avoids the confusion of compatibility of Samba and CTDB
1888 versions as existed previously.
1890 To build the Samba file server with cluster support, use the configure
1891 command line option --with-cluster-support. This will build clustered
1892 file server against the in-tree CTDB and will also build CTDB.
1893 Building clustered samba with previous versions of CTDB is no longer
1896 Samba Registry Editor
1897 =====================
1899 The utitlity to browse the samba registry has been overhauled by our Google
1900 Summer of Code student Chris Davis. Now samba-regedit has a
1901 Midnight-Commander-like theme and UI experience. You can browse keys and edit
1902 the diffent value types. For a data value type a hexeditor has been
1905 Bad Password Lockout in the AD DC
1906 =================================
1908 Samba's AD DC now implements bad password lockout (on a per-DC basis).
1910 That is, incorrect password attempts are tracked, and accounts locked
1911 out if too many bad passwords are submitted. There is also a grace
1912 period of 60 minutes on the previous password when used for NTLM
1913 authentication (matching Windows 2003 SP1: https://support2.microsoft.com/kb/906305).
1915 The relevant settings can be seen using 'samba-tool domain
1916 passwordsettings show' (the new settings being highlighted):
1918 Password informations for domain 'DC=samba,DC=example,DC=com'
1920 Password complexity: on
1921 Store plaintext passwords: off
1922 Password history length: 24
1923 Minimum password length: 7
1924 Minimum password age (days): 1
1925 Maximum password age (days): 42
1926 * Account lockout duration (mins): 30 *
1927 * Account lockout threshold (attempts): 0 *
1928 * Reset account lockout after (mins): 30 *
1930 These values can be set using 'samba-tool domain passwordsettings set'.
1932 Correct defaults in the smb.conf manpages
1933 =========================================
1935 The default values for smb.conf parameters are now correctly specified
1936 in the smb.conf manpage, even when they refer to build-time specified
1937 paths. Provided Samba is built on a system with the right tools
1938 (xsltproc in particular) required to generate our man pages, then
1939 these will be built with the exact same embedded paths as used by the
1940 configuration parser at runtime. Additionally, the default values
1941 read from the smb.conf manpage are checked by our test suite to match
1942 the values seen in testparm and used by the running binaries.
1944 Consistent behaviour between samba-tool testparm and testparm
1945 =============================================================
1947 With the exception of the registry backend, which remains only
1948 available in the file server, the behaviour of the smb.conf parser and
1949 the tools 'samba-tool testparm' and 'testparm' is now consistent,
1950 particularly with regard to default values. Except with regard to
1951 registry shares, it is no longer needed to use one tool on the AD
1952 DC, and another on the file server.
1957 A VFS module for basic WORM (Write once read many) support has been
1958 added. It allows an additional layer on top of a Samba share, that provides
1959 a basic set of WORM functionality on the client side, to control the
1960 writeability of files and folders.
1962 As the module is simply an additional layer, share access and permissions
1963 work like expected - only WORM functionality is added on top. Removing the
1964 module from the share configuration, removes this layer again. The
1965 filesystem ACLs are not affected in any way from the module and treated
1968 The module does not provide complete WORM functions, like some archiving
1969 products do! It is not audit-proof, because the WORM function is only
1970 available on the client side, when accessing a share through SMB! If
1971 the same folder is shared by other services like NFS, the access only
1972 depends on the underlying filesystem ACLs. Equally if you access the
1973 content directly on the server.
1975 For additional information, see
1976 https://wiki.samba.org/index.php/VFS/vfs_worm
1978 vfs_fruit, a VFS module for OS X clients
1979 ========================================
1981 A new VFS module that provides enhanced compatibility with Apple SMB
1982 clients and interoperability with a Netatalk 3 AFP fileserver.
1984 The module features enhanced performance with reliable named streams
1985 support, interoperability with special characters commonly used by OS
1986 X client (eg '*', '/'), integrated file locking and Mac metadata
1987 access with Netatalk 3 and enhanced performance by implementing
1988 Apple's SMB2 extension codenamed "AAPL".
1990 The modules behaviour is fully configurable, please refer to the
1991 manpage vfs_fruit for further details.
1993 smbclient archival improvements
1994 ===============================
1996 Archive creation and extraction support in smbclient has been rewritten
1997 to use libarchive. This fixes a number of outstanding bugs in Samba's
1998 previous custom tar implementation and also adds support for the
1999 extraction of zipped archives.
2000 smbclient archive support can be enabled or disabled at build time with
2001 corresponding --with[out]-libarchive configure parameters.
