94 Release Notes for Samba 4.1.1
96 =============================
99 This is a security release in order to address
100 CVE-2013-4475 (ACLs are not checked on opening an alternate
101 data stream on a file or directory) and
102 CVE-2013-4476 (Private key in key.pem world readable).
105 Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x,
106 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying
107 file or directory ACL when opening an alternate data stream.
109 According to the SMB1 and SMB2+ protocols the ACL on an underlying
110 file or directory should control what access is allowed to alternate
111 data streams that are associated with the file or directory.
113 By default no version of Samba supports alternate data streams
114 on files or directories.
116 Samba can be configured to support alternate data streams by loading
117 either one of two virtual file system modues (VFS) vfs_streams_depot or
118 vfs_streams_xattr supplied with Samba, so this bug only affects Samba
119 servers configured this way.
121 To determine if your server is vulnerable, check for the strings
122 "streams_depot" or "streams_xattr" inside your smb.conf configuration
126 In setups which provide ldap(s) and/or https services, the private
127 key for SSL/TLS encryption might be world readable. This typically
128 happens in active directory domain controller setups.

140 * BUG 10234: CVE-2013-4476: Private key in key.pem world readable.

166 =============================
167 Release Notes for Samba 4.1.0
169 =============================
172 This is is the first stable release of Samba 4.1.
174 Samba 4.1 will be the next version of the Samba suite and includes
175 all the technology found in both the Samba4 series and the stable 3.x
176 series. The primary additional features over Samba 3.6 are
177 support for the Active Directory logon protocols used by Windows 2000
180 Major enhancements in Samba 4.1.0 include:
182 Client tools support SMB2/3
183 ===========================
185 Samba 4.1.0 contains the first release of our client tools
186 and client library that work over the new protocols SMB2 or SMB3.
187 Note that SMB3 only works either to a Samba server version 4.0.0
188 or above, or to a Windows Server running Windows 2012 or Windows 8.
190 The default protocol for smbclient and smbcacls is still
191 SMB1 (the NT1 protocol dialect). An SMB2 or SMB3 connection
192 can be selected in one of two ways. The easiest way to test
193 the new protocol connection is to add the -mMAX_PROTOCOL
194 command line switch to either smbclient or smbcacls.
196 For example, to connect using SMB3 with smbclient a user
199 smbclient //server/share -Uuser%password -mSMB3
201 Another example of connecting using SMB2 using smbcacls
204 smbcacls //server/share -Uuser%password -mSMB2 filename
206 Note that when connecting using SMB2 or SMB3 protocols
207 the UNIX extensions are no longer available inside the
208 smbclient command set. This is due to UNIX extensions
209 not yet being defined for the SMB2 or SMB3 protocols.
211 The second way to select SMB2 or SMB3 connections is to
212 set the "client max protocol" parameter in the [global]
213 section of your smb.conf.
215 Setting this parameter will cause all client connections
216 from Samba and its client tools to offer the requested
217 max protocol to a server on every connection request.
219 For example, to cause all client tools (including winbindd,
220 rpcclient, and the libsmbclient library) to attempt use SMB3
221 by default add the line:
223 client max protocol = SMB3
225 to the [global] section of your smb.conf. This has not
226 been as widely tested as the -mPROTOCOL options, but
227 is intended to work correctly in the final release of
233 Although Samba servers have supported encrypted transport
234 connections using the UNIX extensions for many years,
235 selecting SMB3 transport allows encrypted transport
236 connections to Windows servers that support SMB3, as
237 well as Samba servers.
239 In order to enable this, add the "-e" option to the
240 smbclient command line.
242 For example, to connect to a Windows 2012 server over
243 SMB3 and select an encrypted transport you would use
244 the following command line:
246 smbclient //Win2012Server/share -Uuser%password -mSMB3 -e
249 Directory database replication (AD DC mode)
250 ===========================================
252 Directory replication has been reworked in order to improve the
253 correctness and efficiency.
254 As a net effect of it, replication with other domain controllers with
255 a heavily modified schema is now possible (ie. Windows 2012 DCs or
256 other Windows DC with exchange installed) and replication didn't fail
257 anymore in such environments.
260 Server-Side Copy Support
261 ========================
263 Samba 4.1.0 adds support for server-side copy operations via the SMB2
264 FSCTL_SRV_COPYCHUNK request. Clients making use of server-side copy
265 support, such as Windows Server 2012, should experience considerable
266 performance improvements for file copy operations, as file data need not
267 traverse the network.
268 This feature is enabled by default on the smbd file server.
271 Btrfs Filesystem Integration
272 ============================
274 The Btrfs VFS module provided with Samba 4.1.0 further improves the
275 performance of server-side copy operations on shares backed by a Btrfs
276 filesystem. It does so by allowing multiple files to share the same
277 on-disk extents, avoiding the unnecessary duplication of source and
278 destination file data during a server-side copy operation.
280 This feature can be explicitly enabled on smbd shares backed by a Btrfs
281 filesystem with the smb.conf parameter:
288 The Samba Web Administration Tool (SWAT) has been removed.
289 Details why SWAT has been removed can be found on the samba-technical mailing
