Release Announcements
=====================
-This is the first preview release of Samba 4.6. This is *not*
+This is the first preview release of Samba 4.8. This is *not*
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 4.6 will be the next version of the Samba suite.
+Samba 4.8 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").
+NEW FEATURES/CHANGES
+====================
-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.
+Using x86_64 Accelerated AES Crypto Instructions
+================================================
-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.
+Samba on x86_64 can now be configured to use the Intel accelerated AES
+instruction set, which has the potential to make SMB3 signing and
+encryption much faster on client and server. To enable this, configure
+Samba using the new option --accel-aes=intelaesni.
-Users who were using the wrong spelling "ressource" with two "s" can keep the
-setting, but are advised to switch to the correct spelling.
+This is a temporary solution that is being included to allow users
+to enjoy the benefits of Intel accelerated AES on the x86_64 platform,
+but the longer-term solution will be to move Samba to a fully supported
+external crypto library.
-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.
-
-
-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.
-
-
-REMOVED FEATURES
-================
+The third_party/aesni-intel code will be removed from Samba as soon as
+external crypto library performance reaches parity.
+The default is to build without setting --accel-aes, which uses the
+existing Samba software AES implementation.
smb.conf changes
================
- Parameter Name Description Default
- -------------- ----------- -------
- kerberos encryption types New all
- inherit owner New option
- fruit:resource Spelling correction
+ Parameter Name Description Default
+ -------------- ----------- -------
+ oplock contention limit Removed
+
+NT4-style replication based net commands removed
+================================================
+The following commands and sub-commands have been removed from the
+"net" utility:
+
+net rpc samdump
+net rpc vampire ldif
+
+Also, replicating from a real NT4 domain with "net rpc vampire" and
+"net rpc vampire keytab" has been removed.
+
+The NT4-based commands were accidentially broken in 2013, and nobody
+noticed the breakage. So instead of fixing them including tests (which
+would have meant writing a server for the protocols, which we don't
+have) we decided to remove them.
+
+For the same reason, the "samsync", "samdeltas" and "database_redo"
+commands have been removed from rpcclient.
+
+"net rpc vampire keytab" from Active Directory domains continues to be
+supported.
KNOWN ISSUES
============
