intended for production environments and is designed for testing
purposes only. Please report any defects via the Samba bug reporting
system at https://bugzilla.samba.org/.

+Samba 4.7 will be the next version of the Samba suite.
UPGRADING
=========
-vfs_fruit option "fruit:resource" spelling correction
------------------------------------------------------
-
-Due to a spelling error in the vfs_fruit option parsing for the "fruit:resource"
-option, users who have set this option in their smb.conf were still using the
-default setting "fruit:resource = file" as the parser was looking for the string
-"fruit:ressource" (two "s").
-
-After upgrading to this Samba version 4.6, you MUST either remove the option
-from your smb.conf or set it to the default "fruit:resource = file", otherwise
-your macOS clients will not be able to access the resource fork data.
-
-This version Samba 4.6 accepts both the correct and incorrect spelling, but the
-next Samba version 4.7 will not accept the wrong spelling.
-
-Users who were using the wrong spelling "ressource" with two "s" can keep the
-setting, but are advised to switch to the correct spelling.
-
-ID Mapping
-----------
-We discovered that the majority of users have an invalid or incorrect
-ID mapping configuration. We implemented checks in the 'testparm' tool to
-validate the ID mapping configuration. You should run it and check if it prints
-any warnings or errors after upgrading! If it does you should fix them. See the
-'IDENTITY MAPPING CONSIDERATIONS' section in the smb.conf manpage.
-There are some ID mapping backends which are not allowed to be used for the
-default backend. Winbind will no longer start if an invalid backend is
-configured as the default backend.
-
-To avoid problems in future we advise all users to run 'testparm' after
-changing the smb.conf file!
-
NEW FEATURES/CHANGES
====================
-Kerberos client encryption types
---------------------------------
-Some parts of Samba (most notably winbindd) perform Kerberos client
-operations based on a Samba-generated krb5.conf file. A new
-parameter, "kerberos encryption types" allows configuring the
-encryption types set in this file, thereby allowing the user to
-enforce strong or legacy encryption in Kerberos exchanges.
-
-The default value of "all" is compatible with previous behavior, allowing
-all encryption algorithms to be negotiated. Setting the parameter to "strong"
-only allows AES-based algorithms to be negotiated. Setting the parameter to
-"legacy" allows only RC4-HMAC-MD5 - the legacy algorithm for Active Directory.
-This can solves some corner cases of mixed environments with Server 2003R2 and
-newer DCs.
-
-Printing
---------
-Support for uploading printer drivers from newer Windows clients (Windows 10)
-has been added until our implementation of [MS-PAR] protocol is ready.
-Several issues with uploading different printing drivers have been addressed.
-
-The OS Version for the printing server has been increased to announce
-Windows Server 2003 R2 SP2. If a driver needs a newer version then you should
-check the smb.conf manpage for details.
-
-new option for owner inheritance
---------------------------------
-The "inherit owner" smb.conf parameter instructs smbd to set the
-owner of files to be the same as the parent directory's owner.
-Up until now, this parameter could be set to "yes" or "no".
-A new option, "unix only", enables this feature only for the UNIX owner
-of the file, not affecting the SID owner in the Windows NT ACL of the
-file. This can be used to emulate something very similar to folder quotas.
-
-Multi-process Netlogon support
-------------------------------
-
-The Netlogon server in the Samba AD DC can now run as multiple
-processes. The Netlogon server is a part of the AD DC that handles
-NTLM authentication on behalf of domain members, including file
-servers, NTLM-authenticated web servers and 802.1x gateways. The
-previous restriction to running as a single process has been removed,
-and it will now run in the same process model as the rest of the
-'samba' binary.
-
-As part of this change, the NETLOGON service will now run on a distinct
-TCP port, rather than being shared with all other RPC services (LSA,
-SAMR, DRSUAPI etc).
-
-new options for controlling TCP ports used for RPC services
------------------------------------------------------------
-
-The new 'rpc server port' option controls the default port used for
-RPC services other than Netlogon. The Netlogon server honors instead
-the 'rpc server port:netlogon' option. The default value for both
-these options is the first available port including or after 1024.
-
-Improve AD performance and replication improvements
----------------------------------------------------
-
-Samba's LDB and replication code continues to improve, particularly in
-respect to the handling of large numbers of linked attributes. We now
-respect an 'uptodateness vector' which will dramatically reduce the
-over-replication of links from new DCs. We have also made the parsing
-of on-disk linked attributes much more efficient.
-
-DNS improvements
-----------------
-
-The samba-tool dns subcommand is now much more robust and can delete
-records in a number of situations where it was not possible to do so
-in the past.
-
-On the server side, DNS names are now more strictly validated.
-
-CTDB changes
-------------
+The "strict sync" global parameter has been changed from
+a default of "no" to "yes". This means smbd will by default
+obey client requests to synchronize unwritten data in operating
+system buffers safely onto disk. This is a safer default setting
+for modern SMB1/2/3 clients.
+
+Authentication and Authorization audit support
+----------------------------------------------
+
+Detailed authentication and authorization audit information is now
+logged to Samba's debug logs under the "auth_audit" debug class,
+including in particular the client IP address triggering the audit
+line. Additionally, if Samba is compiled against the jansson JSON
+library, a JSON representation is logged under the "auth_json_audit"
+debug class.
+
+Audit support is comprehensive for all authentication and
+authorisation of user accounts in the Samba Active Directory Domain
+Controller, as well as the implicit authentication in password
+changes. In the file server and classic/NT4 domain controller, NTLM
+authentication, SMB and RPC authorization is covered, however password
+changes are not at this stage, and this support is not currently
+backed by a testsuite.
-* "ctdb event" is a new top-level command for interacting with event scripts
-
- "ctdb event status" replaces "ctdb scriptstatus" - the latter is
- maintained for backward compatibility but the output format has been
- cleaned up
-
- "ctdb event run" replaces "ctdb eventscript"
-
- "ctdb event script enable" replaces "ctdb enablescript"
-
- "ctdb event script disable" replaces "ctdb disablescript"
-
- The new command "ctdb event script list" lists event scripts.
-
-* CTDB's back-end for running event scripts has been replaced by a
- separate, long-running daemon ctdbd_eventd.
-
-* Running ctdb interactively will log to stderr
-
-* CTDB logs now include process id for each process
-
-* CTDB tags log messages differently. Changes include:
-
- ctdb-recoverd: Messages from CTDB's recovery daemon
- ctdb-recovery: Messages from CTDB database recovery
- ctdb-eventd: Messages from CTDB's event daemon
- ctdb-takeover: Messgaes from CTDB's public IP takeover subsystem
-
-* The mapping between symbolic and numeric debug levels has changed
+smb.conf changes
+================
- Configurations containing numeric debug levels should be updated.
- Symbolic debug levels are recommended. See the DEBUG LEVEL section
- of ctdb(7) for details.
+ Parameter Name Description Default
+ -------------- ----------- -------
+ auth event notification New parameter no
+ auth methods Deprecated
+ map untrusted to domain Deprecated
+ strict sync Default changed yes
-* Tunable IPAllocAlgorithm replaces LCP2PublicIPs, DeterministicIPs
+Removal of lpcfg_register_defaults_hook()
+-----------------------------------------
- See ctdb-tunables(7) for details
+The undocumented and unsupported function lpcfg_register_defaults_hook()
+that was used by external projects to call into Samba and modify
+smb.conf default parameter settings has been removed. If your project
+was using this call please raise the issue on
+samba-technical@lists.samba.org in order to design a supported
+way of obtaining the same functionality.
-* CTDB's configuration tunables should be consistently set across a cluster
+Change of loadable module interface
+-----------------------------------
- This has always been the cases for most tunables but this fact is
- now documented.
+The _init function of all loadable modules in Samba has changed
+from:
-* CTDB ships with recovery lock helper call-outs for etcd and Ceph RADOS
+NTSTATUS _init(void);
- To build/install these, use the --enable-etcd-reclock and
- --enable-ceph-reclock configure options.
+to:
+NTSTATUS _init(TALLOC_CTX *);
-smb.conf changes
-================
-
- Parameter Name Description Default
- -------------- ----------- -------
- kerberos encryption types New all
- inherit owner New option
- fruit:resource Spelling correction
- lsa over netlogon New (deprecated) no
- rpc server port New 0
-
+This allows a program loading a module to pass in a long-lived
+talloc context (which must be guaranteed to be alive for the
+lifetime of the module). This allows modules to avoid use of
+the talloc_autofree_context() (which is inherently thread-unsafe)
+and still be valgrind-clean on exit. Modules that don't need to
+free long-lived data on exist should use the NULL talloc context.
