-
-New Security Defaults for Authentication
-========================================
+Samba 4.2 will be the next version of the Samba suite.
-Support for LanMan passwords is now disabled in both client and server
-applications. Additionally, clear text authentication requests are
-disabled by default in client utilities such as smbclient and all
-libsmbclient based applications. This will affect connection both
-to and from hosts running DOS, Windows 9x/ME, and OS/2. Please refer
-to the "Changes" section for details on the exact parameters that were
-updated.
+UPGRADING
+=========
-Registry Configuration Backend
-==============================
+Read the "Winbindd/Netlogon improvements" section (below) carefully!
-Samba is now able to use a registry based configuration backed to
-supplement smb.conf settings. This feature may be enabled by setting
-"config backend = registry" in the [global] section of smb.conf for a
-registry only configuration, or by specifying "include = registry" to
-include global options from registry for a mixed setup.
-The new parameter "registry shares = yes" in the [global] section of
-smb.conf can be used to activate share definitions from registry.
-These shares are loaded on demand by the server. Registry shares are
-automatically activated by the global registry options above.
+NEW FEATURES
+============
-The configuration stored in registry can be conveniently managed using
-the "net conf" command.
+Transparent File Compression
+============================
-More information may be obtained from the smb.conf(5) and net(8) man
-pages.
+Samba 4.2.0 adds support for the manipulation of file and folder
+compression flags on the Btrfs filesystem.
+With the Btrfs Samba VFS module enabled, SMB2+ compression flags can
+be set remotely from the Windows Explorer File->Properties->Advanced
+dialog. Files flagged for compression are transparently compressed
+and uncompressed when accessed or modified.
+Previous File Versions with Snapper
+===================================
-Removed Features
-================
+The newly added Snapper VFS module exposes snapshots managed by
+Snapper for use by Samba. This provides the ability for remote
+clients to access shadow-copies via Windows Explorer using the
+"previous versions" dialog.
-Both the Python bindings and the libmsrpc shared library have been
-removed from the tree due to lack of an official maintainer.
-
-As smbfs is no longer supported in current kernel versions, smbmount has
-been removed in this Samba version. Please use cifs (mount.cifs) instead.
-See examples/scripts/mount/mount.smbfs as an example for a wrapper which
-calls mount.cifs instead of smbmount/mount.smbfs.
-
-
-Modified API for libsmbclient
-==============================================================================
-
-Maintaining ABI compatibility for libsmbclient has become increasingly
-difficult to accomplish, while also keeping the code organization such that it
-is easily readable. Towards the goal of maintaining ABI compatibility and
-also keeping the code easy to maintain and enhance, the API has been enhanced.
-In particular, the fields in the SMBCCTX context structure are no longer
-intended to be read/write by the user, and are marked as deprecated. An
-application that previously accessed the members of the SMBCCTX context
-structure will now encounter warnings if recompiled. This is intentional, to
-encourage implementation of the small changes required for the new interface.
-The number of changes is expected to be quite small for the vast majority of
-applications, and no changes need be made for many applications. The changes
-required for KDE (konqueror) to conform to the new interface, for example, are
-only four lines in only one file.
-
-Instead of the application manually changing or reading values in the context
-structure, there are now setter and getter functions for each configurable
-member in that structure. Similarly, the smbc_option_get() and
-smbc_option_set() functions are deprecated in favor of the setter/getter
-interface. The setters and getters are all documented in libsmbclient.h
-under these comment blocks:
-
- Getters and setters for CONFIGURATION
- Getters and setters for OPTIONS
- Getters and setters for FUNCTIONS
- Callable functions for files
- Callable functions for directories
- Callable functions applicable to both files and directories
-
-Example changes that may be required to eliminate "deprecated" warnings:
-
- /* Set the debug level */
- context->debug = 99;
-changes to:
- smbc_setDebug(context, 99);
-
- /* Specify the authentication callback function */
- context->callbacks.auth_fn = auth_smbc_get_data;
-changes to:
- smbc_setFunctionAuthData(context, auth_smbc_get_data);
-
- /* Specify the new-style authentication callback with context parameter */
- smbc_option_set("auth_function", auth_smbc_get_data_with_ctx);
-changes to:
- smbc_setFunctionAuthDataWithContext(context, auth_smbc_get_data_with_ctx);
-
- /* Set kerberos flags */
- context->flags = (SMB_CTX_FLAG_USE_KERBEROS |
- SMB_CTX_FLAG_FALLBACK_AFTER_KERBEROS);
-changes to:
- smbc_setOptionUseKerberos(context, 1);
- smbc_setOptionFallbackAfterKerberos(context, 1);
+Winbindd/Netlogon improvements
+==============================
+The whole concept of maintaining the netlogon secure channel
+to (other) domain controllers was rewritten in order to maintain
+global state in a netlogon_creds_cli.tdb. This is the proper fix
+for a large number of bugs:
+ https://bugzilla.samba.org/show_bug.cgi?id=6563
+ https://bugzilla.samba.org/show_bug.cgi?id=7944
+ https://bugzilla.samba.org/show_bug.cgi?id=7945
+ https://bugzilla.samba.org/show_bug.cgi?id=7568
+ https://bugzilla.samba.org/show_bug.cgi?id=8599
+In addition a strong session key is now required by default,
+which means that communication to older servers or clients
+might be rejected by default.
-######################################################################
-Changes
-#######
+For the client side we have the following new options:
+"require strong key" (yes by default), "reject md5 servers" (no by default).
+E.g. for Samba 3.0.37 you need "require strong key = no" and
+for NT4 DCs you need "require strong key = no" and "client NTLMv2 auth = no",
-smb.conf changes
-----------------
+On the server side (as domain controller) we have the following new options:
+"allow nt4 crypto" (no by default), "reject md5 client" (no by default).
+E.g. in order to allow Samba < 3.0.27 or NT4 members to work
+you need "allow nt4 crypto = yes"
+
+winbindd does not list group memberships for display purposes
+(e.g. getent group <domain\<group>) anymore by default.
+The new default is "winbind expand groups = 0" now,
+the reason for this is the same as for "winbind enum users = no"
+and "winbind enum groups = no". Providing this information is not always
+reliably possible, e.g. if there are trusted domains.

-
-Original 3.2.0pre1 commits:
----------------------------
-o Michael Adam <obnox@samba.org>
- * Unified POSIX ACL detection including support for FreeBSD and
- HP-UX.
- * Performance improvements for Winbind's lookup functions (names,
- SIDs, and group membership) when joined to an AD domain.
- * Winbind cache validation support.
- * Store domain trust passwords for Samba domain controller's in
- the domain's passdb backend.
- * Merged \winreg server code from the SAMBA_3_2 development branch.
- * Fixes for libreplace.
- * Implement new registry configuration backend.
+Please consult the smb.conf manpage for more details on these new options.
+Winbindd use on the Samba AD DC
+===============================
-o Jeremy Allison <jra@samba.org>
- * Add support for file system objectIDs.
- * Winbind cache validation support.
- * Add in the UNIX capability for 24-bit readX.
- * Improve Delete-on-Close semantics.
- * Removal of static file and path name buffers in SMB file serving
- code.
+Winbindd is now used on the Samba AD DC by default, replacing the
+partial rewrite used for winbind operations in Samba 4.0 and 4.1.
+This allows more code to be shared, more options to be honoured, and
+paves the way for support for trusted domains in the AD DC.
-o Danilo Almeida <dalmeida@centeris.com>
- * Move the machine account to the OU specified when running "net
- ads join".
+If required the old internal winbind can be activated by setting
+'server services = +winbind -winbindd'. Upgrading users with a server
+services parameter specified should ensure they change 'winbind' to
+'winbindd' to obtain the new functionality.
+The 'samba' binary still manages the starting of this service, there
+is no need to start the winbindd binary manually.
-o Andrew Bartlett <abartlet@samba.org>
- * Tighten authentication protocol defaults in client tools and
- servers.
+Winbind now requires secured connections
+========================================
+To improve protection against rouge domain controllers we now require
+that when we connect to an AD DC in our forest, that the connection be
+signed using SMB Signing. Set 'client signing = off' in the smb.conf
+to disable.
-o Gerald (Jerry) Carter <jerry@samba.org>
- * Implement support for one-way trusts and two-way cross-forest
- transitive trust in winbindd.
- * Fixes for Winbind's offline/disconnected logon support when
- using remote idmap backends.
- * Fix LookupNames and LookupSids to use the same resolution
- heuristics as Windows XP.
- * Fix lockups in Winbind when running nscd.
- * UPN logon support in pam_winbind.
- * Add support for GNU linker scripts when build shared libraries
- (based on work by Julien Cristau <jcristau@debian.org> and James
- Peach).
+Also and DCE/RPC pipes must be sealed, set 'require strong key =
+false' and 'winbind sealed pipes = false' to disable.
+Finally, the default for 'client ldap sasl wrapping' has been set to
+'sign', to ensure the integrity of LDAP connections. Set 'client ldap
+sasl wrapping = plain' to disable.
-o Guenther Deschner <gd@samba.org>
- * Additional support for decoding and downloading group policy
- objects from Active Directory.
- * Improvements to "net ads keytab" command.
- * Fixes for linking against Heimdal Kerberos client libs.
- * Support LDAP range retrieval searches.
- * Fixes for failure to refresh user ticket caches in Winbind.
- * UPN logon support in pam_winbind.
- * Add KDC locator plugin for MIT kerberos 1.6 or later.
+Larger IO sizes for SMB2/3 by default
+=====================================
+The default values for "smb2 max read", "smb2 max write" and "smb2 max trans"
+have been changed to 8388608 (8MiB) in order to match the default of
+Windows 2012R2.
-o Steve Langasek <vorlon@debian.org>
- * Allow SIGTERM to cause nmbd to exit while awaiting a interface
- to come up.
+Improved DCERPC man in the middle detection
+===========================================
+The DCERPC header signing has been implemented
+in addition to the dcerpc_sec_verification_trailer
+protection.
-o Volker Lendecke <vl@samba.org>
- * Merge experimental cluster support patches from the ctdb branch.
- * Add tdb storage abstraction for ctdb.
- * Use IDL for internal message passing system.
- * Add client support for the SamLogonEx() authentication request.
- * Implement RPC proxy stubs in the Samba server code to allow
- replacing implementation functions one by one.
- * Remove static incoming and outgoing buffers from core server SMB
- packet processing code.
- * Add "net sam rights" command.
+Overhauled "net idmap" command
+==============================
+The command line interface of the "net idmap" command has been
+made systematic, and subcommands for reading and writing the autorid idmap
+database have been added. Note that the writing commands should be
+used with great care. See the net(8) manual page for details.
-o Steve French <sfrench@samba.org>
- * Fixes for mount.cifs Linux utility.
+tdb improvements
+================
+The tdb library, our core mechanism to store Samba-specific data on disk and
+share it between processes, has been improved to support process shared robust
+mutexes on Linux. These mutexes are available on Linux and Solaris and
+significantly reduce the overhead involved with tdb. To enable mutexes for
+tdb, set
-o Stefan Metzmacher <metze@samba.org>
- * Fixes for libreplace.
- * Add support for LDAP digital signing policy.
- * Experimental clustered file system support.
+dbwrap_tdb_mutexes:* = yes
+in the [global] section of your smb.conf.
-o Lars Mueller <lars@samba.org>
- * Makefile and build fixes.
- * Add pam_pwd_expire for pam_winbind (original patch from Andreas
- Schneider).
+Tdb file space management has also been made more efficient. This
+will lead to smaller and less fragmented databases.
+Messaging improvements
+======================
-o James Peach <jpeach@apple.com>
- * Fixes for setgroups() and *BSD and Darwin.
- * Support membership of >16 groups on Darwin.
+Our internal messaging subsystem, used for example for things like oplock
+break messages between smbds or setting a process debug level dynamically, has
+been rewritten to use unix domain datagram messages.
+Clustering support
+==================
-o Jiri Sasek <Jiri.Sasek@Sun.COM>
- * Added vfs_zfsacl module.
+Samba's file server clustering component CTDB is now integrated in the
+Samba tree. This avoids the confusion of compatibility of Samba and CTDB
+versions as existed previously.
+To build the Samba file server with cluster support, use the configure
+command line option --with-cluster-support. This will build clustered
+file server against the in-tree ctdb. Building clustered samba with
+previous versions of CTDB is no longer supported.
-o Karolin Seeger <ks@sernet.de>
- * Add deletelocalgroup and unmapunixgroup subcommand to "net sam".
- * Cleanup internal passdb functions.
+CTDB is built separately from the ctdb/ sub-directory. To build CTDB,
+use the following steps:
+ $ cd ctdb
+ $ ./configure
+ $ make
+ # make install
-o Simo Sorce <idra@samba.org>
- * Fixes for IDmap and Passdb backends.
