233 Release Notes for Samba 4.5.3
235 =============================
238 This is a security release in order to address the following defects:
240 o CVE-2016-2123 (Samba NDR Parsing ndr_pull_dnsp_name Heap-based Buffer
241 Overflow Remote Code Execution Vulnerability).
242 o CVE-2016-2125 (Unconditional privilege delegation to Kerberos servers in
244 o CVE-2016-2126 (Flaws in Kerberos PAC validation can trigger privilege
252 The Samba routine ndr_pull_dnsp_name contains an integer wrap problem,
253 leading to an attacker-controlled memory overwrite. ndr_pull_dnsp_name
254 parses data from the Samba Active Directory ldb database. Any user
255 who can write to the dnsRecord attribute over LDAP can trigger this
258 By default, all authenticated LDAP users can write to the dnsRecord
259 attribute on new DNS objects. This makes the defect a remote privilege
263 Samba client code always requests a forwardable ticket
264 when using Kerberos authentication. This means the
265 target server, which must be in the current or trusted
266 domain/realm, is given a valid general purpose Kerberos
267 "Ticket Granting Ticket" (TGT), which can be used to
268 fully impersonate the authenticated user or service.
271 A remote, authenticated, attacker can cause the winbindd process
272 to crash using a legitimate Kerberos ticket due to incorrect
273 handling of the arcfour-hmac-md5 PAC checksum.
275 A local service with access to the winbindd privileged pipe can
276 cause winbindd to cache elevated access permissions.
282 o Volker Lendecke <vl@samba.org>
283 * BUG 12409: CVE-2016-2123: Fix DNS vuln ZDI-CAN-3995.
285 o Stefan Metzmacher <metze@samba.org>
286 * BUG 12445: CVE-2016-2125: Don't send delegated credentials to all servers.
287 * BUG 12446: CVE-2016-2126: auth/kerberos: Only allow known checksum types in
288 check_pac_checksum().

539 =============================
540 Release Notes for Samba 4.5.0
542 =============================
545 This is the first stable release of the Samba 4.5 release series.
551 NTLMv1 authentication disabled by default
552 -----------------------------------------
554 In order to improve security we have changed
555 the default value for the "ntlm auth" option from
556 "yes" to "no". This may have impact on very old
557 clients which doesn't support NTLMv2 yet.
559 The primary user of NTLMv1 is MSCHAPv2 for VPNs and 802.1x.
561 By default, Samba will only allow NTLMv2 via NTLMSSP now,
562 as we have the following default "lanman auth = no",
563 "ntlm auth = no" and "raw NTLMv2 auth = no".
569 Support for LDAP_SERVER_NOTIFICATION_OID
570 ----------------------------------------
572 The ldap server has support for the LDAP_SERVER_NOTIFICATION_OID
573 control. This can be used to monitor the Active Directory database
576 KCC improvements for sparse network replication
577 -----------------------------------------------
579 The Samba KCC will now be the default knowledge consistency checker in
580 Samba AD. Instead of using full mesh replication between every DC, the
581 KCC will set up connections to optimize replication latency and cost
582 (using site links to calculate the routes). This change should allow
583 larger domains to function significantly better in terms of replication
584 traffic and the time spent performing DRS replication.
586 VLV - Virtual List View
587 -----------------------
589 The VLV Control allows applications to page the LDAP directory in the
590 way you might expect a live phone book application to operate, without
591 first downloading the entire directory.
593 DRS Replication for the AD DC
594 -----------------------------
596 DRS Replication in Samba 4.5 is now much more efficient in handling
597 linked attributes, particularly in large domains with over 1000 group
598 memberships or other links.
600 Replication is also much more reliable in the handling of tree
601 renames, such as the rename of an organizational unit containing many
602 users. Extensive tests have been added to ensure this code remains
603 reliable, particularly in the case of conflicts between objects added
604 with the same name on different servers.
606 Schema updates are also handled much more reliably.
608 samba-tool drs replicate with new options
609 -----------------------------------------
611 'samba-tool drs replicate' got two new options:
613 The option '--local-online' will do the DsReplicaSync() via IRPC
614 to the local dreplsrv service.
616 The option '--async-op' will add DRSUAPI_DRS_ASYNC_OP to the
617 DsReplicaSync(), which won't wait for the replication result.
619 replPropertyMetaData Changes
620 ----------------------------
622 During the development of the DRS replication, tests showed that Samba
623 stores the replPropertyMetaData object incorrectly. To address this,
624 be aware that 'dbcheck' will now detect and offer to fix all objects in
625 the domain for this error.
627 For further information and instructions how to fix the problem, see
628 https://wiki.samba.org/index.php/Updating_Samba#Fixing_replPropertyMetaData_Attributes
630 Linked attributes on deleted objects
631 ------------------------------------
633 In Active Directory, an object that has been tombstoned or recycled
634 has no linked attributes. However, Samba incorrectly maintained such
635 links, slowing replication and run-time performance. 'dbcheck' now
636 offers to remove such links, and they are no longer kept after the
637 object is tombstoned or recycled.
639 Improved AD DC performance
640 --------------------------
642 Many other improvements have been made to our LDAP database layer in
643 the AD DC, to improve performance, both during 'samba-tool domain
644 provision' and at runtime.
646 Other dbcheck improvements
647 --------------------------
649 - 'samba-tool dbcheck' can now find and fix a missing or corrupted
650 'deleted objects' container.
651 - BUG 11433: samba-dbcheck no longer offers to resort auxiliary class values
652 in objectClass as these were then re-sorted at the next dbcheck indefinitely.
654 Tombstone Reanimation
655 ---------------------
657 Samba now supports tombstone reanimation, a feature in the AD DC
658 allowing tombstones, that is objects which have been deleted, to be
659 restored with the original SID and GUID still in place.
661 Multiple DNS Forwarders on the AD DC
662 ------------------------------------
664 Previously, the Samba internal DNS server supported only one DNS forwarder.
665 The "dns forwarder" option has been enhanced and now supports a space-separated
666 list of multiple DNS server IP addresses. As a result, Samba is now able to
667 fall back to alternative DNS servers. In case that a DNS query to the first
668 server timed out, it is sent to the next DNS server listed in the option.
670 Password quality plugin support in the AD DC
671 --------------------------------------------
673 The check password script now operates correctly in the AD DC.
675 pwdLastSet is now correctly honoured
676 ------------------------------------
678 BUG 9654: The pwdLastSet attribute is now correctly handled (this previously
679 permitted passwords that expire next).
681 net ads dns unregister
682 ----------------------
684 It is now possible to remove the DNS entries created with 'net ads register'
685 with the matching 'net ads unregister' command.
687 samba-tool improvements
688 ------------------------
690 Running 'samba-tool' on the command line should now be a lot snappier. The tool
691 now only loads the code specific to the subcommand that you wish to run.
693 SMB 2.1 Leases enabled by default
694 ---------------------------------
696 Leasing is an SMB 2.1 (and higher) feature which allows clients to
697 aggressively cache files locally above and beyond the caching allowed
698 by SMB 1 oplocks. This feature was disabled in previous releases, but
699 the SMB2 leasing code is now considered mature and stable enough to be
702 Open File Description (OFD) Locks
703 ---------------------------------
705 On systems that support them (currently only Linux), the fileserver now
706 uses Open File Description (OFD) locks instead of POSIX locks to implement
707 client byte range locks. As these locks are associated with a specific
708 file descriptor on a file this allows more efficient use when multiple
709 descriptors having file locks are opened onto the same file. An internal
710 tunable "smbd:force process locks = true" may be used to turn off OFD
711 locks if there appear to be problems with them.
713 Password sync as Active Directory domain controller
714 ---------------------------------------------------
716 The new commands 'samba-tool user getpassword'
717 and 'samba-tool user syncpasswords' provide
718 access and syncing of various password fields.
720 If compiled with GPGME support (--with-gpgme) it's
721 possible to store cleartext passwords in a PGP/OpenGPG
722 encrypted form by configuring the new "password hash gpg key ids"
723 option. This requires gpgme devel and python packages to be installed
724 (e.g. libgpgme11-dev and python-gpgme on Debian/Ubuntu).
726 Python crypto requirements
727 --------------------------
729 Some 'samba-tool' subcommands require python-crypto and/or
730 python-m2crypto packages to be installed.
732 SmartCard/PKINIT improvements
733 -----------------------------
735 'samba-tool user create' accepts "--smartcard-required"
736 and 'samba-tool user setpassword' accepts "--smartcard-required"
737 and "--clear-smartcard-required".
739 Specifying "--smartcard-required" results in the UF_SMARTCARD_REQUIRED
740 flags being set in the userAccountControl attribute.
741 At the same time, the account password is reset to a random
744 Interactive password logons are rejected, if the UF_SMARTCARD_REQUIRED
745 bit is set in the userAccountControl attribute of a user.
747 When doing a PKINIT based Kerberos logon the KDC adds the
748 required PAC_CREDENTIAL_INFO element to the authorization data.
749 That means the NTHASH is shared between the PKINIT based client and
750 the domain controller, which allows the client to do NTLM based
751 authentication on behalf of the user. It also allows an offline
752 logon using a smartcard to work on Windows clients.
757 * New improved 'ctdb tool'
759 'ctdb tool' has been completely rewritten using new client API.
760 Usage messages are much improved.
762 * Sample CTDB configuration file is installed as ctdbd.conf.
764 * The use of real-time scheduling when taking locks has been narrowed
765 to limit potential performance impacts on nodes.
767 * CTDB_RECOVERY_LOCK now supports specification of an external helper
768 to take and hold the recovery lock.
770 See the RECOVERY LOCK section in ctdb(7) for details. Documentation
771 for writing helpers is provided in doc/cluster_mutex_helper.txt.
773 * "ctdb natgwlist" has been replaced by a top level "ctdb natgw"
774 command that has "master", "list" and "status" subcommands.
776 * The 'onnode' command no longer supports the "recmaster", "lvs" and
777 "natgw" node specifications.
779 * Faster resetting of TCP connections to public IP addresses during
782 * Tunables MaxRedirectCount, ReclockPingPeriod,
783 DeferredRebalanceOnNodeAdd are now obsolete/ignored.
785 * "ctdb listvars" now lists all variables, including the first one.
787 * "ctdb xpnn", "ctdb rebalanceip" and "ctdb rebalancenode" have been
790 These are not needed because "ctdb reloadips" should do the correct
793 * Output for the following commands has been simplified:
803 These now simply print the requested output with no preamble. This
804 means that scripts no longer need to strip part of the output.
806 "ctdb getreclock" now prints nothing when the recovery lock is not
809 * Output for the following commands has been improved:
814 * 'ctdb process-exists' has been updated to only take a PID argument.
816 The PNN can be specified with -n <PNN>. Output also cleaned up.
818 * LVS support has been reworked - related commands and configuration
819 variables have changed.
821 'ctdb lvsmaster' and 'ctdb lvs' have been replaced by a top level
822 'ctdb lvs' command that has 'master', 'list' and 'status'
825 See the LVS sections in ctdb(7) and ctdbd.conf(5) for details,
826 including configuration changes.
828 * Improved sample NFS Ganesha call-out.
830 New shadow_copy2 options
831 ------------------------
835 With growing number of snapshots file-systems need some mechanism to
836 differentiate one set of snapshots from other, e.g. monthly, weekly, manual,
837 special events, etc. Therefore, these file-systems provide different ways to tag
838 snapshots, e.g. provide a configurable way to name snapshots, which is not just
839 based on time. With only shadow:format it is very difficult to filter these
840 snapshots. With this optional parameter, one can specify a variable prefix
841 component for names of the snapshot directories in the file-system. If this
842 parameter is set, together with the shadow:format and shadow:delimiter
843 parameters it determines the possible names of snapshot directories in the
844 file-system. The option only supports Basic Regular Expression (BRE).
848 This optional parameter is used as a delimiter between "shadow:snapprefix" and
849 "shadow:format". This parameter is used only when "shadow:snapprefix" is set.
851 Default: shadow:delimiter = "_GMT"
857 "only user" and "username" parameters
858 -------------------------------------
860 These two parameters have long been deprecated and superseded by
861 "valid users" and "invalid users".
867 Parameter Name Description Default
868 -------------- ----------- -------
869 kccsrv:samba_kcc Changed default yes
870 ntlm auth Changed default no
872 password hash gpg key ids New
873 shadow:snapprefix New
874 shadow:delimiter New _GMT
875 smb2 leases Changed default yes
882 While a lot of schema replication bugs were fixed in this release
883 Bug 12204 - Samba fails to replicate schema 69
884 (https://bugzilla.samba.org/show_bug.cgi?id=12204) is still open.
885 The replication fails if more than 133 schema objects are added
