-What's new in Samba 4.0 beta8
-=============================
+ =============================
+ Release Notes for Samba 4.1.6
+ March 11, 2014
+ =============================
+
+
+This is a security release in order to address
+CVE-2013-4496 (Password lockout not enforced for SAMR password changes) and
+CVE-2013-6442 (smbcacls can remove a file or directory ACL by mistake).
+
+o CVE-2013-4496:
+ Samba versions 3.4.0 and above allow the administrator to implement
+ locking out Samba accounts after a number of bad password attempts.
+
+ However, all released versions of Samba did not implement this check for
+ password changes, such as are available over multiple SAMR and RAP
+ interfaces, allowing password guessing attacks.
+
+o CVE-2013-6442:
+ Samba versions 4.0.0 and above have a flaw in the smbcacls command. If
+ smbcacls is used with the "-C|--chown name" or "-G|--chgrp name"
+ command options it will remove the existing ACL on the object being
+ modified, leaving the file or directory unprotected.
+
+
+Changes since 4.1.5:
+--------------------
+
+o Jeremy Allison <jra@samba.org>
+ * BUG 10327: CVE-2013-6442: ensure we don't lose an existing ACL when
+ setting owner or group owner.
+
+
+o Andrew Bartlett <abartlet@samba.org>
+ * BUG 10245: CVE-2013-4496: Enforce password lockout for SAMR password
+ changes.
+
+
+o Stefan Metzmacher <metze@samba.org>
+ * BUG 10245: CVE-2013-4496: Enforce password lockout for SAMR password

+ =============================
+ Release Notes for Samba 4.1.3
+ December 9, 2013
+ =============================
+
+
+This is a security release in order to address
+CVE-2013-4408 (DCE-RPC fragment length field is incorrectly checked) and
+CVE-2012-6150 (pam_winbind login without require_membership_of restrictions).
+
+o CVE-2013-4408:
+ Samba versions 3.4.0 and above (versions 3.4.0 - 3.4.17, 3.5.0 -
+ 3.5.22, 3.6.0 - 3.6.21, 4.0.0 - 4.0.12 and including 4.1.2) are
+ vulnerable to buffer overrun exploits in the client processing of
+ DCE-RPC packets. This is due to incorrect checking of the DCE-RPC
+ fragment length in the client code.
+
+ This is a critical vulnerability as the DCE-RPC client code is part of
+ the winbindd authentication and identity mapping daemon, which is
+ commonly configured as part of many server installations (when joined
+ to an Active Directory Domain). A malicious Active Directory Domain
+ Controller or man-in-the-middle attacker impersonating an Active
+ Directory Domain Controller could achieve root-level access by
+ compromising the winbindd process.
+
+ Samba server versions 3.4.0 - 3.4.17 and versions 3.5.0 - 3.5.22 are
+ also vulnerable to a denial of service attack (server crash) due to a
+ similar error in the server code of those versions.
+
+ Samba server versions 3.6.0 and above (including all 3.6.x versions,
+ all 4.0.x versions and 4.1.x) are not vulnerable to this problem.
+
+ In addition range checks were missing on arguments returned from calls
+ to the DCE-RPC functions LookupSids (lsa and samr), LookupNames (lsa and samr)
+ and LookupRids (samr) which could also cause similar problems.
+
+ As this was found during an internal audit of the Samba code there are
+ no currently known exploits for this problem (as of December 9th 2013).
+
+o CVE-2012-6150:
+ Winbind allows for the further restriction of authenticated PAM logins using
+ the require_membership_of parameter. System administrators may specify a list
+ of SIDs or groups for which an authenticated user must be a member of. If an
+ authenticated user does not belong to any of the entries, then login should
+ fail. Invalid group name entries are ignored.
+
+ Samba versions 3.3.10, 3.4.3, 3.5.0 and later incorrectly allow login from
+ authenticated users if the require_membership_of parameter specifies only
+ invalid group names.
+
+ This is a vulnerability with low impact. All require_membership_of group
+ names must be invalid for this bug to be encountered.
+
+
+Changes since 4.1.2:
+--------------------
+
+o Jeremy Allison <jra@samba.org>
+ * BUG 10185: CVE-2013-4408: Correctly check DCE-RPC fragment length field.
+
+
+o Stefan Metzmacher <metze@samba.org>
+ * BUG 10185: CVE-2013-4408: Correctly check DCE-RPC fragment length field.
+
+
+o Noel Power <noel.power@suse.com>
+ * BUGs 10300, 10306: CVE-2012-6150: Fail authentication if user isn't
+ member of *any* require_membership_of specified groups.

+ Release Notes for Samba 4.1.1
+ November 11, 2013
+ =============================
+
+
+This is a security release in order to address
+CVE-2013-4475 (ACLs are not checked on opening an alternate
+data stream on a file or directory) and
+CVE-2013-4476 (Private key in key.pem world readable).
+
+o CVE-2013-4475:
+ Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x,
+ 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying
+ file or directory ACL when opening an alternate data stream.
+
+ According to the SMB1 and SMB2+ protocols the ACL on an underlying
+ file or directory should control what access is allowed to alternate
+ data streams that are associated with the file or directory.
+
+ By default no version of Samba supports alternate data streams
+ on files or directories.
+
+ Samba can be configured to support alternate data streams by loading
+ either one of two virtual file system modues (VFS) vfs_streams_depot or
+ vfs_streams_xattr supplied with Samba, so this bug only affects Samba
+ servers configured this way.
+
+ To determine if your server is vulnerable, check for the strings
+ "streams_depot" or "streams_xattr" inside your smb.conf configuration
+ file.
+
+o CVE-2013-4476:
+ In setups which provide ldap(s) and/or https services, the private
+ key for SSL/TLS encryption might be world readable. This typically
+ happens in active directory domain controller setups.
+
+

+ Release Notes for Samba 4.1.0
+ October 11, 2013
+ =============================
+
+
+This is is the first stable release of Samba 4.1.
+
+Samba 4.1 will be the next version of the Samba suite and includes
+all the technology found in both the Samba4 series and the stable 3.x
+series. The primary additional features over Samba 3.6 are
support for the Active Directory logon protocols used by Windows 2000
and above.
+Major enhancements in Samba 4.1.0 include:
-WARNINGS
-========
+Client tools support SMB2/3
+===========================
-Samba 4.0 beta8 is not a final Samba release, however we are now making
-good progress towards a Samba 4.0 release. However, this is expected to be the
-last beta release before we start on our release candidate series.
+Samba 4.1.0 contains the first release of our client tools
+and client library that work over the new protocols SMB2 or SMB3.
+Note that SMB3 only works either to a Samba server version 4.0.0
+or above, or to a Windows Server running Windows 2012 or Windows 8.
-This release contains the best of all of Samba's
-technology parts, both a file server (that you can reasonably expect
-to upgrade existing Samba 3.x releases to) and the AD domain
-controller work previously known as 'samba4'.
+The default protocol for smbclient and smbcacls is still
+SMB1 (the NT1 protocol dialect). An SMB2 or SMB3 connection
+can be selected in one of two ways. The easiest way to test
+the new protocol connection is to add the -mMAX_PROTOCOL
+command line switch to either smbclient or smbcacls.
-Samba 4.0 is subjected to an awesome battery of tests on an automated
-basis, we have found Samba 4.0 to be very stable in it's behaviour.
-However, as with all our pre-releases we still recommend against
-upgrading production servers from Samba 3.x release to Samba 4.0 beta
-at this stage.
+For example, to connect using SMB3 with smbclient a user
+would type:
-If you are upgrading, or looking to develop, test or deploy Samba 4.0
-beta releases, you should backup all configuration and data.
+smbclient //server/share -Uuser%password -mSMB3
+Another example of connecting using SMB2 using smbcacls
+would be:
-UPGRADING
-=========
+smbcacls //server/share -Uuser%password -mSMB2 filename
-Users upgrading from Samba 3.x domain controllers and wanting to use
-Samba 4.0 as an AD DC should use the 'samba-tool domain
-classicupgrade' command. See the wiki for more details:
-https://wiki.samba.org/index.php/Samba4/samba3upgrade/HOWTO
+Note that when connecting using SMB2 or SMB3 protocols
+the UNIX extensions are no longer available inside the
+smbclient command set. This is due to UNIX extensions
+not yet being defined for the SMB2 or SMB3 protocols.
-Users upgrading from Samba 4.0 alpha and beta releases since alpha15
-should run 'samba-tool dbcheck --cross-ncs --fix' before re-starting
-Samba. Users upgrading from earlier alpha releases should contact the
-team for advice.
+The second way to select SMB2 or SMB3 connections is to
+set the "client max protocol" parameter in the [global]
+section of your smb.conf.
-Users upgrading an AD DC from any previous release should run
-'samba-tool ntacl sysvolreset' to re-sync ACLs on the sysvol share
-with those matching the GPOs in LDAP and the defaults from an initial
-provision. This will set an underlying POSIX ACL if required (eg not
-using the NTVFS file server).
+Setting this parameter will cause all client connections
+from Samba and its client tools to offer the requested
+max protocol to a server on every connection request.
-NEW FEATURES
-============
+For example, to cause all client tools (including winbindd,
+rpcclient, and the libsmbclient library) to attempt use SMB3
+by default add the line:
-Samba 4.0 beta supports the server-side of the Active Directory logon
-environment used by Windows 2000 and later, so we can do full domain
-join and domain logon operations with these clients.
+client max protocol = SMB3
-Our Domain Controller (DC) implementation includes our own built-in
-LDAP server and Kerberos Key Distribution Center (KDC) as well as the
-Samba3-like logon services provided over CIFS. We correctly generate
-the infamous Kerberos PAC, and include it with the Kerberos tickets we
-issue.
+to the [global] section of your smb.conf. This has not
+been as widely tested as the -mPROTOCOL options, but
+is intended to work correctly in the final release of
+4.1.0.
-Samba 4.0 beta ships with two distinct file servers. We now use the
-file server from the Samba 3.x series 'smbd' for all file serving by
-default.
+Encrypted transport
+===================
-Samba 4.0 also ships with the 'NTVFS' file server. This file server
-is what was used in all previous alpha releases of Samba 4.0, and is
-tuned to match the requirements of an AD domain controller. We
-continue to support this, not only to provide continuity to
-installations that have deployed it as part of an AD DC, but also as a
-running example of the NT-FSA architecture we expect to move smbd to in
-the longer term.
+Although Samba servers have supported encrypted transport
+connections using the UNIX extensions for many years,
+selecting SMB3 transport allows encrypted transport
+connections to Windows servers that support SMB3, as
+well as Samba servers.
-For pure file server work, the binaries users would expect from that
-series (nmbd, winbindd, smbpasswd) continue to be available. When
-running an AD DC, you only need to run 'samba' (not
-nmbd/smbd/winbind), as the required services are co-coordinated by this
-master binary.
+In order to enable this, add the "-e" option to the
+smbclient command line.
-As DNS is an integral part of Active Directory, we also provide a DNS
-solution, using the BIND DLZ mechanism in versions 9.8 and 9.9.
-During the provision, a configuration file will be generated for bind
-to make it use this plugin. We also have a project to provide a
-minimal internal DNS server from within the Samba process, for easier
-'out of the box' configuration. Note however that this is not yet
-complete (pending addition of secure DNS update support).
+For example, to connect to a Windows 2012 server over
+SMB3 and select an encrypted transport you would use
+the following command line:
-To provide accurate timestamps to Windows clients, we integrate with
-the NTP project to provide secured NTP replies. To use you need to
-start ntpd and configure it with the 'restrict ... ms-sntp' and
-ntpsigndsocket options.
+smbclient //Win2012Server/share -Uuser%password -mSMB3 -e
-Finally, a new scripting interface has been added to Samba 4, allowing
-Python programs to interface to Samba's internals, and many tools and
-internal workings of the DC code is now implemented in python.
+Directory database replication (AD DC mode)
+===========================================
-CHANGES SINCE beta7
-=====================
+Directory replication has been reworked in order to improve the
+correctness and efficiency.
+As a net effect of it, replication with other domain controllers with
+a heavily modified schema is now possible (ie. Windows 2012 DCs or
+other Windows DC with exchange installed) and replication didn't fail
+anymore in such environments.
-For a list of changes since beta7, please see the git log.

+Server-Side Copy Support
+========================
-Some major user-visible changes include:
+Samba 4.1.0 adds support for server-side copy operations via the SMB2
+FSCTL_SRV_COPYCHUNK request. Clients making use of server-side copy
+support, such as Windows Server 2012, should experience considerable
+performance improvements for file copy operations, as file data need not
+traverse the network.
+This feature is enabled by default on the smbd file server.
-- A fix for a segfault/abort on startup of the 'samba' binary in the
- credentials_secrets code.
-- A fix for samba-tool classicupgrade of pdb_ldap-based domains
+Btrfs Filesystem Integration
+============================
-- A fix for samba-tool domain exportkeyab only exporting DES keys
+The Btrfs VFS module provided with Samba 4.1.0 further improves the
+performance of server-side copy operations on shares backed by a Btrfs
+filesystem. It does so by allowing multiple files to share the same
+on-disk extents, avoiding the unnecessary duplication of source and
+destination file data during a server-side copy operation.
-- Printing is now enabled on the AD DC
+This feature can be explicitly enabled on smbd shares backed by a Btrfs
+filesystem with the smb.conf parameter:
+vfs objects = btrfs
-- Fix bug #9124 - Samba fails to set "inherited" bit on inherited ACE's.
-- We now avoid printing secret attributes (such as unicodePwd and
- suppliementalCredentials) in ldb trace logs
+REMOVED COMPONENTS
+==================
-- s3-printing: fix bug 9123 lprng job tracking errors
+The Samba Web Administration Tool (SWAT) has been removed.
+Details why SWAT has been removed can be found on the samba-technical mailing
+list:
-- A fix for building with MIT Kerberos
+https://lists.samba.org/archive/samba-technical/2013-February/090572.html
-KNOWN ISSUES
-============
-- 'samba-tool domain classicupgrade' will fail when setting ACLs on
- the GPO folders with NT_STATUS_INVALID_ONWER in the default
- configuration. This happens if, as is typical a 'domain admins'
- group (-512) is mapped in the passdb backend being upgraded. This
- is because the group mapping to a GID only prevents Samba from
- allocating a uid for that group. The uid is needed so the 'domain
- admins' group can own the GPO file objects.
+######################################################################
+Changes
+#######
- To work around this issue, remove the 'domain admins' group before
- upgrade, as it will be re-created automatically. You will
- of course need to fill in the group membership again. A future release
- will make this automatic, or find some other workaround.
+smb.conf changes
+----------------
-- This release makes the s3fs file server the default, as this is the
- file server combination we will use for the Samba 4.0 release.
+ Parameter Name Description Default
+ -------------- ----------- -------
-- For similar reasons, sites with ACLs stored by the ntvfs file server
- may wish to continue to use that file server implementation, as a
- posix ACL will similarly not be set in this case.
+ acl allow execute always New False
+ password level Removed
+ set directory Removed
+ use ntdb New No
-- Replication of DNS data from one AD server to another may not work.
- The DNS data used by the internal DNS server and bind9_dlz is stored
- in an application partition in our directory. The replication of
- this partition is not yet reliable.
-- Replication may fail on FreeBSD due to getaddrinfo() rejecting names
- containing _. A workaround will be in a future beta.
+RUNNING Samba 4.1 as an AD DC
+=============================
-- upgradeprovision should not be run when upgrading to this release
- from a recent release. No important database format changes have
- been made since alpha16.
+A short guide to setting up Samba as an AD DC can be found on the wiki:
-- Installation on systems without a system iconv (and developer
- headers at compile time) is known to cause errors when dealing with
- non-ASCII characters.
+ https://wiki.samba.org/index.php/Samba_AD_DC_HOWTO
-- Domain member support in the 'samba' binary is in it's infancy, and
- is not comparable to the support found in winbindd. As such, do not
- use the 'samba' binary (provided for the AD server) on a member
- server.
-- There is no NetBIOS browsing support (network neighbourhood)
- available for the AD domain controller. (Support in nmbd and smbd
- for classic domains and member/standalone servers is unchanged).
+COMMIT HIGHLIGHTS
+=================
-- Clock Synchronisation is critical. Many 'wrong password' errors are
- actually due to Kerberos objecting to a clock skew between client
- and server. (The NTP work in the previous alphas are partly to assist
- with this problem).
+o Jeremy Allison <jra@samba.org>
+ * Add SMB2 and SMB3 support for client tools and client library.
+ * Add support for SMB3 Encrypted transport.
-- The DRS replication code may fail. Please contact the team if you
- experience issues with DRS replication, as we have fixed many issues
- here in response to feedback from our production users.
+o David Disseldorp <ddiss@samba.org>
+ * Add vfs_btrfs module.
+ * Add support for server-side copy operations via the
